A Papyrus commentary on Alcman published in 19571 brings us news of a poem in which Alcman “physiologized”. The lemmata and commentary together witness to a semi-philosophical cosmogony unlike any other hitherto known from Greece. The evidence is meagre, but it seems worth while to see what can be made of it; for it is perhaps possible to go a little farther than has so far been done.

Quantum electrodynamics is the theory of electrons and other elementary charged particles, interacting through the exchange of light quanta. Albert Einstein introduced the light quantum in 1905, but for about three decades physicists applied quantum ideas mainly in theories of the structure and behavior of matter, not to electromagnetic radiation itself, which was always treated semi-classically. This began to change after 1923 with the discovery of the Compton effect and its kinematic description by Arthur Compton and Peter Debye, based on (...) the light quantum. In this paper we review the study of high-energy radiation that led to Compton's discovery. We discuss the analysis of the intensity distribution of Compton-scattered radiation that together with the ''new'' quantum theory beginning in 1925, resulted in the development, especially by Pascual Jordan and Paul Dirac, of a quantum theory of electromagnetic radiation in interaction with matter.

What if human joy went on endlessly? Suppose, for example, that each human generation were followed by another, or that the Western religions are right when they teach that each human being lives eternally after death. If any such possibility is true in the actual world, then an agent might sometimes be so situated that more than one course of action would produce an infinite amount of utility. Deciding whether to have a child born this year rather than next is (...) a situation wherein an agent may face several alternatives whose effects could well ramify endlessly on such suppositions, for the child born this year would be a different person—one who preferred different things, performed different actions, and had different descendants—from a child born next year. It has recently been suggested that traditional utilitarianism stumbles on such cases of infinite utility. Specifically, utilitarianism seems to require, for its application, that all experience of pleasure and pain cease at some time in the future or asymptotically approach zero.2 If neither of these conditions holds, then the utility produced by each of two alternative actions may turn out to be infinite, and utilitarianism thus loses its ability to discriminate morally between them.

Maternity careproviders often have strong views concerning a woman’s choice of where to give birth. These views may be based on the ethical principle of autonomy, or on the principle of beneficence. The authors propose that an approach utilizing shared decision making allows careproviders and women to move beyond disagreements regarding which evidence on risk should “count,” instead adopting a process of increased knowledge and support for women and their partner while they make choices regarding place of birth.

On 31 December 1957 the deputy director of the Institute of Philosophy of the USSR Academy of Science, A. F. Okulov, informed me that I had been hired as a junior research fellow. In the following year, Voprosy filosofii published my first article, which was followed by other articles. Since then I have left the Institute several times and have published a lot in other journals and publishing houses, but for me the Institute and Voprosy remain forever my philosophical Home, (...) an axis around which my intricate fate took shape. Hence, for me the journal's fiftieth anniversary is not simply one more anniversary, however solemn and honored it may be, but an emotional and joyful event in my own life, an existential frontier.

In CQ 20 , 277–87, 1 argued for dating Corinna to the third century B.C. In my Greek Metre , p. 141, I continued to assume this date, observing that not everyone accepted it but that I knew of no attempt to answer my arguments. I must confess to having overlooked at least one such attempt, by A. Allen in CJ 68 , 26–8; and now M. Davies has mounted another in SIFC 81 , 186–94, largely repeating Allen's points but (...) with some new touches. Allen upholds the traditional fifth-century date. Davies has yet to come to a decision, but meanwhile he is eager to discredit what he regards as an unsatisfactory case for a Hellenistic dating. (shrink)

The first critical edition of the _Syncategoreumata_ by the thirteenth-century philosopher Peter of Spain, accompanied by a facing-page English translation to make its contents accessible to modern readers. The introduction gives an account of all the manuscripts used for the edition. Extensive indexes have been added to facilitate the reader's orientation in the book.

Histories of literature tend to treat Stesichorus as just one of the lyric poets, like Alcman or Anacreon. But the vast scale of his compositions puts him in a category of his own. It has always been known that his Oresteia was divided into more than one book; P. Oxy, 2360 gave us fragments of a narrative about Telemachus of a nearly Homeric amplitude; and from P. Oxy. 2617 it was learned that the Geryoneis contained at least 1,300 verses, the (...) total being perhaps closer to two thousand. Even allowing for the shorter lines, this was as long as many an epic poem. Indeed, these were epic poems, in subject and style as well as in length: epics to be sung instead of recited. What was behind them ? Who was this Stesichorus, and how did he come to be, in Quintilian's phrase, ‘sustaining on the lyre the weight of epic song’ ? The biographical problem must be tackled first. The question of Stesichorus’ historical setting and date is confused by legendary elements as well as by contradiction in the sources. On the whole scholars remain spellbound by the specious precision of the Suda's dates , although it has long been realized that they are founded on nothing but the assumption that Stesichorus was younger than Alcman and older than Simonides. There have been excellent discussions by Wilamowitz and Maas, but they seem to have had little influence. (shrink)

Résumé : Le PPBS a été conçu comme un instrument destiné à ceux qui décident de l'allocation des ressources publiques : il doit leur permettre de prendre de meilleures décisions. S'il est très difficile de repérer et de juger les choix que le développement du système a inspirés aux Etats-Unis, il n'en est pas mains certain que ses résultats tangibles sant maigres car la masse des anciens programmes, principale source potentielle de moyens nouveaux, n'a guère été remise en question.La valeur (...) intrinsèque du PPBS ne peut être mise en cause. Ce qui doit l'être, c'est la lenteur de son développement, qui demeure peu avancé. Cette lenteur s'explique, car le système ne peut produire des fruits dans une terre stérile qu'on n'a pas préparée.La brutalité et les maladresses de l'opération déclenchée en 1965 dans le gouvernement fédéral américain ne pouvaient que renforcer la résistance au changement et retarder, sinon compromettre, le succès final. Les perspectives demeurent heureusement favorables, puisque la nouvelle administration ne semble pas décidée à faire machine arrière et que les Etats et Villes ont démarré sous de bien meilleurs auspices.La principale conclusion qu'imposent les expériences américaines est que toute juridiction intéressée par le PPBS doit impérativement développer, de la façon la plus générale, la volonté d'instaurer le système et s'assurer les moyens de le faire. C'est dire qu'il est peu sage d'engager la bataille sur tous les fronts à la fois : il faut tenter des percées. Mais c'est dire aussi combi en l'information et la formation sant essentielles. A cet égard, l'installation généralisée de certains éléments du système, à savoir la structure de programmes et le budget-programme, loin de présenter des inconvénients, peut constituer un excellent exercice en dehors de son utilité directe pour le preneur de décision. La bataille en cause est surtout celle de la conviction: l'outil est prêt, il est bon, encore faut-il que l' ouvrier accepte de s'en servir.Samenvatting:Planning-programming-budgeting werd ontworpen als een instrument voor diegenen die beslissen over de toewijzing van de overheidsmiddelen.Dit instrument moet de beslissers in staat stellen betere beslissingen te treffen. Het is niet makkelijk deze beslissingen op te sporen en te beoordelen welke in de Verenigde Staten getroffen werden onder invloed van de ontwikkeling van deze systeembenadering. Toch is het met vrij grote zekerheid te stellen dat de tastbare resultaten gering zijn omdat de veelheid aan oude programma's die tenslotte toch de voornaamste potentiële bronnen zijn van nieuwe middelen, nooit werden aangevochten.De intrinsieke waarde van PPBS kan daarom evenwel niet worden genegeerd. Wat wel dient aangeklaagd is de traagheid van zijn aanslepende ontwikkeling. Deze traagheid is te verklaren door het feit dat het systeem slechts vruchten kan afwerpen zo het ingeplant wordt in degelijk voorbereid terrein.De brutaliteit en de onhandigheden bij de operatie die in 1965 werd ingezet in het amerikaans federaal overheidsbestel konden niets anders dan de weerstand tegen de verandering versterken en afbreuk doen aan het uiteindelijk slagen van het systeem. Gelukkiglijk blijven de vooruitzichten gunstig want de nieuwe beleidsvoerders sinds de presidentsverkiezingen, blijken ermee te willen doorgaan en de staten en lokale overheden zijn ermee van wal gestoken onder veel betere omstandigheden. Het doorslaggevend besluit uit de amerikaanse ervaringen terzake is wel dat elke instantie welke belangstelling heeft voor PPBS, nodig moet op zo breed mogelijk vlak de wil doen groeien om het systeem te ontwikkelen en er ook de nodige middelen toe ter beschikking stellen. Dit betekent tevens dat het weinig aan te bevelen is de strijd op alle fronten terzelvertijd aan te binden maar wel geleidelijk doorbraken te verwezenlijken. Dit brengt dan evenwel ook met zich dat informatie en vorming essentieel zijn bij deze strategie. In dit verband moet dan ook gezegd worden dat reeds het invoeren van sommige deelementen van het systeem, zoals de programmastructuur en het programmabudget, voor de beslisser nuttig kan zijn voor zijn persoonlijk inzicht en vorming.De te voeren actie dient nog slechts te worden toegespitst op het overtuigen van de verantwoordelijken. Het instrument is immers gebruiksklaar en degelijk, er is alleen nog het wachten op de wil van de gebruiker dit instrument ter hand te nemen. (shrink)

This article deals with the control of chaos on the convective motion in a ferrofluid filled in a rotating porous medium and under the helical force effect. We performed a truncated expansion of Galerkin and found the Lorenz-type model which described the system. The dynamical system is characterized using appropriate and subsequent criteria. We noticed that the system presents regular and chaotic behaviors according to the parameters at present. A considerable reduction of the chaotic domain is noticed with the increase (...) of the intensity of the helical force and of the Darcy number, thus making it possible to delay the heat transfer in the system. The increase in the viscosity ratio and the Taylor number widen the chaotic domain leading to an acceleration of the heat transfer in the system. (shrink)

The context shows that the intention of the lines was to bring out the surpassing beauty of a certain girl and its value to the chorus as a whole. When the Pleiades rise up the sky, they are followed by a star that far outshines them all: Sirius. In Alcman's image, then, the Pleiades should correspond to the chorus and Sirius to the girl. The point of opdpiaiis that the comparison is not chosen at random, but suggested by something to (...) be seen during the current ceremonies: the Pleiades rise up the sky before dawn when we carry the plough, with Sirius down below them, and they seem like a rival group. There is no reference to Ortheia, and no rival chorus. We may translate: ‘For the Pleiades range themselves against us, before dawn, as we bear the plough through the ambrosial night, bringing Sirius up with them as they do.’. (shrink)

It is universally recognized that the Hymn to Ares stands apart from all the other poems in the Homeric collection, and that it was composed centuries later than any of those that can be assigned to a particular period with any degree of confidence. Many older scholars classed it or even printed it with the Orphic Hymns, which are transmitted together with the Homeric Hymns as well as with the hymns of Callimachus and Proclus. But the similarity with the Orphic (...) Hymns is only superficial. It merely consists in the stylistic feature of accumulated epithets, a common characteristic of late hymns. There are three reasons for not lumping the Hymn to Ares with the very homogeneous Orphic series. First, the Orphic Hymns are courteous invocations of different gods to come to a ceremony described as τєλєτή or τєλєτταί, while the Hymn to Ares is an intensely personal prayer for the poet's own soul. Secondly, the Orphic collection already contains a hymn to Ares , and duplications are avoided. Thirdly, in the Homeric hymn Ares is addressed as a planetary god. In the Orphic hymn to Ares, this aspect is totally absent, and the same is true of the hymns to Hermes, Aphrodite, Zeus, and Kronos. (shrink)
