scholarly journals Geometry on plane and optimal linear prognosis

In the article we consider a new scalar production in the linear subspace of n vectors (by analogy with the geometry of Lobachevsky, all two vectors are orthogonal as projections of the third vector). With help of the production we obtain a new form of linear projection of the additional vector to the subspace. The rapid algorithm of finding of optimum linear estimation of additional vector on the known vectors ensues from the projection.

This article is a comment on Peta Spyrou’s article in this volume entitled ‘Civil Liability for Negligence: An Analysis of Cyberbullying Policies in South Australian Schools’. It considers three aspects of the problem: the first focuses on the implications of the fact that  cyberbullying is not a new form of social activity but is rather a new form of bullying; the second explores some of the possible policy and social responses to the problem; and the third draws from the insights of evolutionary economics and underlines the importance of respecting the rights of children both to be protected from bullying as well as to develop their identities.

As mentioned in Chapter II, there are two kinds of LDA approaches: classification- oriented LDA and feature extraction-oriented LDA. In most chapters of this session of the book, we focus our attention on the feature extraction aspect of LDA for SSS problems. On the other hand,, with this chapter we present our studies on the pattern classification aspect of LDA for SSS problems. In this chapter, we present three novel classification-oriented linear discriminant criteria. The first one is large margin linear projection (LMLP) which makes full use of the characteristic of the SSS problems. The second one is the minimum norm minimum squared-error criterion which is a modification of the minimum squared-error discriminant criterion. The third one is the maximum scatter difference which is a modification of the Fisher discriminant criterion.

In the days before the Third Programme changed its name and nature to those of Radio 3, there were occasional broadcast discussions by a group called the Epiphany Philosophers. Since 1966 they have been publishing a journal whose title and sub-title point to the large questions with which the group has continued to be concerned: Theoria to Theory: An International Journal of Science, Philosophy and Contemplative Religion. The editors are conscious of the risks but also of the need to take them:‘We are not now seen as so “way out” as we used to be, because more people are realizing that one has got to go “way out”, and that what is “in” is culturally more dated than some powerful forces would have us believe’. The latest issue (June 1981) is also to be the last, though there is hope of continuing the good work in other ways. The journal itself may be revived ‘in a new form as a much cheaper production’ (the current subscription is £30 for a volume of four issues of 88 pages). There is also a plan under which the publishers, Gordon and Breach, will publish a series of books designed to ‘promote the exploration of new ideas and new applications in philosophy and science through continuing co-operation between philosophers and scientists in different disciplines’. Among the halfpromised volumes is one on The Athletics of Old Age, ‘seen as a spiritual as well as a mental and physical matter’. Others are Revisionary Metaphysics and Revisionary Science, What is Wrong with Contemporary Physics? and How can we move beyond Neo-Darwinism in Biology?.

In the Quart. Journ. Geol. Soc, vol. xxxvi. 1880, p. 617, Mr. John B. Marr mentions having examined three specimens of a Phyllopodiform Crustacean discovered by Mr. Martin Dusl in the strata of “Colonie Haidinger,” situated not far from the village of Gross-chuchle, south of Prague.The specimens were then identified with Discinocaris Browniana, H. Woodw., figured and described in the same Journal, vol. xxii. 1866, p. 503, pi. 25, figs. 4, 5, and 7. They are also mentioned by Dr. H. Woodward and Prof. T. Eupert Jones in the Third Eeport of the Committee on the Fossil Pliyllopoda of the Palaeozoic Eocks, 1885, p. 2, under Mr. Marr's specific determination.

This paper investigates differing forms of attention entailed by the ecphrastic gaze in epic and epigram as a way of considering issues of time and narrative as crucial elements of ecphrasis. Its first section focuses particularly on Paulinus of Nola, who has been almost wholly ignored in recent discussions of ecphrasis, but who not only provides the first example of an ecphrasis of an ecphrasis – the description of an ecphrastic inscription attached to a work of art – but also provides a set of poems which construct the viewer's experience of visiting a church. This is taken as exemplary of a new development of a Christian gaze, a new form of attention. The second section looks specifically at temporality in ecphrasis (through Pliny, Virgil, and epigram), to see how different ideas of time and the experience of looking are inscribed in different genres – which in turn expect and create different forms of knowing. The third section looks particularly at later Greek epigrams, Callistratus and Achilles Tatius, to see how different authors play with ideas of temporality and narrative explored in the first two sections of the paper. Together, these interrelated arguments demonstrate how investigating forms of attention and modes of temporality allows us to develop a more nuanced comprehension of ecphrasis as a historical and aesthetic expression.
