Oxford Scholarly Classics is a new series that makes available again great academic works from the archives of Oxford University Press. Reissued in uniform series design, the reissues will enable libraries, scholars, and students to gain fresh access to some of the finest scholarship of the last century.

The paper is concerned with explaining some of the principal theoretical developments in elementary particle physics and discussing the associated methodological problems both in respect of heuristics and appraisal. Particular reference is made to relativistic quantum field theory, renormalization, Feynman diagram techniques, the analytic S-matrix and the Chew — Frautschi bootstrap.

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)

Objective—To explore the opinions of unpaid healthy volunteers on the payment of research subjects.Design—Prospective cohort.Setting—Southern Alberta, Canada.Participants—Medically eligible persons responding to recruiting advertisements for a randomised vaccine trial were invited to take part in a study of informed consent at the point at which they formally consented or refused trial participation. Of 72 invited, 67 returned questionnaires at baseline and 54 at follow-up.Outcome measures—Proportions of persons who agreed or disagreed with three close-ended statements on the payment of research subjects; themes (...) and categories identified by content analysis of responses to an open-ended question.Results—A minority agreed with paying either patient or healthy volunteer participants. Opinions did not change over time. Participants' comments addressed: benefits and drawbacks to research participation; benefits and drawbacks to paying research participants; conditions under which payment of research subjects would be acceptable, and the nature of acceptable recognition. Acceptable conditions were to improve problematic recruitment, to reimburse costs, and to recognise participants, particularly for their time investment. Both non-monetary and monetary recognition of volunteers were thought to be appropriate.Conclusions—Most unpaid volunteers disagreed with paying research participants. The themes arising from their comments are similar to those that have been raised by ethicists and suggest that recognising the time and effort of participants should receive greater emphasis than presently occurs.

Since its inception in 1968, the concept of whole-brain death has been contentious, and four decades on, controversy concerning the validity and coherence of whole-brain death continues unabated. Although whole-brain death is legally recognized and medically entrenched in the United States and elsewhere, there is reasonable disagreement among physicians, philosophers, and the public concerning whether brain death is really equivalent to death as it has been traditionally understood. A handful of states have acknowledged this plurality of viewpoints and enacted “conscience (...) clauses” that require “reasonable accommodation” of religious and moral objections to the determination of death by neurological criteria. This paper argues for the universal adoption of “reasonable accommodation” policies using the New Jersey statute as a model, in light of both the ongoing controversy and the recent case of Jahi McMath, a child whose family raised religious objections to a declaration of brain death. Public policies that accommodate reasonable, divergent viewpoints concerning death provide a practical and compassionate way to resolve those conflicts that are the most urgent, painful, and difficult to reconcile.

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.

In the long section of anapaests with which they make their entry, the old men of Argos methodically deliver three essential messages to the audience: 40–71. It is the tenth year of the Trojan War. 72–82. We are men who were too old to go and fight in it. 83–103. Some new situation seems to be indicated by the fact that Clytemnestra is organizing sacrifices throughout the town.

Some people have supposed that utility is good in itself, non-in-strumentally good, as distinct from good because conducive to other good things. And in modern versions of this view, utility often means want-satisfaction, as distinct from pleasure or happiness. For your want that p to be satisfied, is it necessary that you know or believe that p, or sufficient merely that p is true? However that question is answered, there are problems with the view that want-satisfaction is a non-instrumental good. (...) What if you want something only because you have a false belief? What if the time at which you want that p is fifty or five hundred years before the time to which p itself refers? To meet these difficulties, qualifications have to be introduced, and much has been written about how exactly these qualifications are to be framed.1 There is however what may be a rather more serious objection to the view that want-satisfaction is a non-instrumental good, or rather to the combination of that view with the principle that it is sufficient for your want that p to be satisfied simply that p is true. The objection is that this combination forces you to give undue weight to the mere acquisition of desires when you come to make judgements about changes in the value of things. It forces you to say that for any true proposition p, which initially you do not want to be true, your mere acquisition of a desire that p will, other things being equal, make the world better. Non-instrumental value can be increased merely by multiplying desires, even though everything else remains the same. Surely, however, improving the world is not as easy as that. (shrink)

It is generally accepted that the Homeric Hymn to Apollo was not conceived as a single poem but is a combination of two: a Delian hymn, D, performed at Delos and concerned with the god's birth there, and a Pythian hymn, P, concerned with his arrival and establishment at Delphi. What above all compels us to make a dichotomy is not the change of scene in itself, but the way D ends. The poet returns from the past to the present, (...) and takes leave of his audience; farewell, he says, and remember me ever after. He is quite clearly finishing. Whereupon there is an abrupt and unsatisfactory transition to P. (shrink)

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)

The work of many scholars in the last hundred years has helped us to understand the nature and origins of the treatise which we know for short as the Contest of Homer and Hesiod. The present state of knowledge may be summed up as follows. The work in its extant form dates from the Antonine period, but much of it was taken over bodily from an earlier source, thought to be the Movaelov of Alcidamas. Some of the verses exchanged in (...) the contest were current even earlier, and some scholars have supposed that the story of a contest went back to the fifth, sixth, or even eighth century; but this is now much doubted.

I shall argue for two complementary theses: firstly that ‘Homer’ was not the name of a historical poet, but a fictitious or constructed name, and secondly that for a century or more after the composition of the Iliad and Odyssey there was little interest in the identity or the person of their author or authors. This interest only arose in the last decades of the sixth century; but once it did, ‘Homer’ very quickly became an object of admiration, criticism, and (...) biographical construction. (shrink)

The total and the sharp character of orthodox quantum logic has been put in question in different contexts. This paper presents the basic ideas for a unified approach to partial and unsharp forms of quantum logic. We prove a completeness theorem for some partial logics based on orthoalgebras and orthomodular posets. We introduce the notion of unsharp orthoalgebra and of generalized MV algebra. The class of all effects of any Hilbert space gives rise to particular examples of these structures. Finally, (...) we investigate the relationship between unsharp orthoalgebras, generalized MV algebras, and orthomodular lattices. (shrink)

City archives, mined by Aristotle for his Didaskaliai, preserved a reasonably complete record of dramatic productions in the fifth century. But how far back did these archives go? The so-called Fasti, an inscription set up c. 346 and listing dithyrambic, comic and tragic victors year by year, must have been based on the same archives, but went back, it is thought, only as far as 502/1. Its heading πρ]τον κμοι ἦσαν τ[ι διονσ]ωι τραγωιδο δ[, however supplemented, implies an intention of (...) going back to the beginning of things, in other words to the beginning of the archival record. This raises serious doubt as to whether that record went back to the alleged date of Thespis' première, or indeed to those given for Choerilus' and Phrynichus'. (shrink)

Two problems are considered here. One relates to who has moral status, and the other relates to who has moral responsibility. The criteria for mattering morally have long been disputed, and many humans and nonhuman animals have been considered “marginal cases,” on the contested edges of moral considerability and concern. The marginalization of humans and other species is frequently the pretext for denying their rights, including the rights to health care, to reproductive freedom, and to bodily autonomy. There is broad (...) agreement across cultural and philosophical traditions about the capacities and responsibilities of moral agents. I propose an inclusive and expansive way of thinking about moral status, situating it not in the characteristics or capacities of individuals, but in the responsibilities and obligations of moral agents. Moral agents, under this view, are not privileged or entitled to special treatment but rather have responsibilities. I approach this by considering some African communitarian conceptions of moral status and moral agency. I propose that moral agency can also be more expansive and include not just individual moral agents but collective entities that have some of the traits of moral agents: power, freedom, and the capacity to recognize and act on the demands of morality and acknowledge and respect the rights of others. Expanding who and what is a moral agent correspondingly extends moral responsibility for respecting rights and fostering the conditions for the health and well-being of humans and animals onto the collective entities who uniquely have the capacity to attend to global-scale health threats such as pandemics and human-caused climate change.

Aims and background: The present work assessed the impact of two decrees on ethics committees in Italy, aimed at bringing the national laws on the conduct of clinical trials into line with the rest of the EC, and regulating and facilitating not-for-profit research.Material and methods: Prospectively collected data from an Italian multicentre study were examined with respect to the ethics review process. Administrative and time elements of the review process were audited. Main outcome measures were time between the application submission (...) and the ethics committee definitive opinion, type and number of application submission forms, number of ethics committees that refused fee exemption, and time between the ethics committee approval and the administrative authorisation.Results: A total of 134 local research ethics committees were approached. Application submission procedures and application forms varied greatly; paper submission was mandatory. The median time from submission to approval was 72 days. Only two LRECs refused the fee exemption. The median time from LREC approval to administrative agreement was 50 days and only 9.6% of local authorities came to a verbal agreement with the sponsor.Conclusions: Italian LRECs are still not sufficiently efficient in complying with the Directive 2001/20/EC requirement . Better coordination of LRECs work is needed although the optimal level of coordination between them is still not known. In the meantime, national guidelines are needed concerning the application of Directive 2001/20/EC. The behaviour of Italian LRECs towards not-for-profit research was excellent although only the fee exemption was requested. (shrink)
