Last year's meetings of the leaders of the party and government with groups of creative artists caused a stir in the field of esthetics, placed in the foreground discussion of questions concerning the theory of the realistic image, and led to an examination of the experience accumulated in the party's struggle for socialist realism. In recent years, as a consequence of the spread of mathematical methods of research into the social sciences and even into creative work, old doubts with respect (...) to the specific significance of the creative image in art have again arisen. For several years now, efforts have been made in esthetics to emphasize, as distinctive features of art, other factors in artistic creativity, more accessible to study by the techniques of the natural sciences.

Polyclonal antibodies raised against the human erythrocyte nucleoside transporter were used to investigate the distribution of the nucleoside transporters in the placenta. Immunoblots of brush-border membranes isolated from the human syncytiotrophoblast revealed a cross-reactive species that co-migrated with the erythrocyte nucleoside transporter as a broad band of apparent M(r) 55,000. In contrast, no labelling was detected in basal membranes containing a similar number of equilibrative nucleoside transporters as assessed by nitrobenzylthioinosine (NBMPR)-binding. The absence of cross-reactive epitopes in basal membranes and (...) their presence in brush-border membranes was confirmed by confocal immunofluorescence microscopy. The results suggest that at least two isoforms of the NBMPR-sensitive nucleoside transporter are present in the human placenta. The lumenal surfaces of fetal capillaries, small placental vessels and umbilical vein ware also strongly labelled by the antibody, a finding that suggests that the high fetal-placental adenosine uptake previously reported is due to endothelial transporters.

In recent years interest in studies of the interrelation of the categories of quality and property has risen in the Soviet philosophical literature. Indeed, this cardinal problem requires further study. The concepts of "quality" and "property" are so close to each other in content in a number of meanings that they are sometimes used as synonyms.1 For further theoretical inquiry it is necessary to define the philosophical meaning of these categories accurately, since otherwise, as Francis Bacon wrote, they will become (...) idols and give rise to errors in our thinking instead of preventing them.

The relation between Jesus and the Spirit appears in diverse occasions and in different contexts in Gregory. Jesus has sanctified the waters in his baptism, from his body springs the Spirit whom he has received in the Jordan, he is the «anointed», the «Christ» par excellence who gives the Holy Spirit to people at Pentecost. The theology of the baptism of the Lord calls for special attention; it takes place at an interesting moment of transition. On the one hand, the (...) effusion of the Spirit on the humanity of Jesus does not create any problem for Gregory who distinguishes it clearly from the incarnation of the Son. On the other hand, the initiative of the Father in this unction is not paid special attention to, nor does it seem that it has a special significance for Jesus himself and the beginning of his mission in the world. However, much stress is given to the ecclesiological dimension of the descent of the Spirit in the baptism of Christ. On him comes the Spirit in fullness, as he will also abide in fullness in the whole Church which is his Body. Each of the Christians receives only a partial gift which must contribute to the perfection of the whole. (shrink)

In the anthropology of Gregory of Elvira there converge different lines of thought. On the one hand he is very dependent on Origen, on the other there is to be found in him the mental framework of Irenaeus and he quotes word for word long passages from Tertullian. The article attempts to determine to what extent, starting from those influences he encountered, Gregory has developed a personal vision of the relationship between Adam and Christ along the double line of the (...) Pauline parallel : sin and grace, initial creation and eschatological fulfilment. If some characteristic passages stress much this second aspect, the majority of the texts analyzed concentrate primarily on the theme of redemption. The reason for the prefiguration of Christ in the creation of Adam, so important for Irenaeus and Tertullian, does not have in Gregory the prominent place which one might have expected to find.

Quine and others have put many problems to quantified modal logic. Their purpose is to show the logic to be paradoxical or at least very peculiar. Many of these problems center around the interplay between modality, quantification and identity.
