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)

An overview of the current epistemic literature concerning conspiracy theories, as well as indications for future research avenues on the topic.

Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, (...) it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

By the colours and decoration of a vase fragment one determines the period and style to which the original belonged; while its physical contours show from what part of the original it comes. The material may be insufficient for a reconstruction of the whole design. But it is often legitimate to go beyond what is actually contained in the preserved pieces.

The manuscript tradition of the Theogony is not as good as that of the Erga, a poem which has always been more popular. The earliest complete manuscripts of the Theogony date only from the end of the thirteenth century, while those upon which the recensio must chiefly be based are of the fourteenth and fifteenth. The number of extant manuscripts, however, especially of the fifteenth century, is not inconsiderable, and knowledge of them has hitherto been far from complete. What is (...) known is known largely in consequence of the labours of Alois Rzach. Rzach collated many of the manuscripts, and tried, with some success, to establish the relationships between them. He published his conclusions in Wiener Studien xix, 15–70, and used them as the basis for his great edition of 1902. (shrink)

For more than sixty years, surgeons have used bioethical strategies to promote patient self‐determination, many of these now collectively described as “informed consent.” Yet the core framework—understanding, risks, benefits, and alternatives—fails to support patients in deliberation about treatment. We find that surgeons translate this framework into an overly complicated technical explanation of disease and treatment and an overly simplified narrative that surgery will “fix” the problem. They omit critical information about the goals and downsides of surgery and present untenable options (...) as a matter of patient choice. We propose a novel framework called “better conversations.” Herein, surgeons provide context about clinical norms, establish the goals of surgery, and comprehensively delineate the downsides of surgery to generate a deliberative space for patients to consider whether surgery is right for them. This paradigm shift meets the standards for informed consent, supports deliberation, and allows patients to anticipate and prepare for the experience of treatment. (shrink)

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)

Background: The factors influencing parents’ willingness to enroll their children in biobanks are poorly understood. This study sought to assess parents’ willingness to enroll their children, and their perceived benefits, concerns, and information needs under different consent and data-sharing scenarios, and to identify factors associated with willingness. Methods: This large, experimental survey of patients at the 11 eMERGE Network sites used a disproportionate stratified sampling scheme to enrich the sample with historically underrepresented groups. Participants were randomized to receive one of (...) three consent and data-sharing scenarios. Results: In total, 90,000 surveys were mailed and 13,000 individuals responded (15.8% response rate). 5737 respondents were parents of minor children. Overall, 55% (95% confidence interval 50–59%) of parents were willing to enroll their youngest minor child in a hypothetical biobank; willingness did not differ between consent and data-sharing scenarios. Lower educational attainment, higher religiosity, lower trust, worries about privacy, and attitudes about benefits, concerns, and information needs were independently associated with less willingness to allow their child to participate. Of parents who were willing to participate themselves, 25% were not willing to allow their child to participate. Being willing to participate but not willing to allow one’s child to participate was independently associated with multiple factors, including race, lower educational attainment, lower annual household income, public health care insurance, and higher religiosity. Conclusions: Fifty-five percent of parents were willing to allow their youngest minor child to participate in a hypothetical biobank. Building trust, protecting privacy, and addressing attitudes may increase enrollment and diversity in pediatric biobanks. (shrink)

The introduction of novel diagnostic techniques in clinical domains such as genomics and radiology has led to a rich ethical debate on how to handle unsolicited findings that result from these innovations. Yet while unsolicited findings arise in both genomics and radiology, most of the relevant literature to date has tended to focus on only one of these domains. In this article, we synthesize and critically assess similarities and differences between “scanning the body” and “sequencing the genome” from an ethical (...) perspective. After briefly describing the novel diagnostic contexts leading to unsolicited findings, we synthesize and reflect on six core ethical issues that relate to both specialties: terminology; benefits and risks; autonomy; disclosure of unsolicited findings to children; uncertainty; and filters and routine screening. We identify ethical rationales that pertain to both fields and may contribute to more ethically sound policies. Considerations of preserving public trust and ensuring that people perceive healthcare policies as fair also support the need for a combined debate. (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)

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.

On the fundamentals of Advaita and Viśiṣṭādvaita philosophy.

Purpose. The research is devoted to the analysis of the urgent problem of the information society: the overload of a person with information and, as a result, the impossibility of adequate formation and development of the personality; as well as the problem of "digitization" of human existence and the formation of a new reality of dataism. Theoretical basis. A lot of modern scientific works are devoted to the analysis of the information society, its problems and features. The information society is (...) a logical continuation of the scientific and technological revolution, which led to the rapid growth of scientific knowledge and the technology development. In the 20th century, technologies have touched the sphere of knowledge and information, as a result of which the formation and development of the information society, or "knowledge society", takes place. Information becomes the main resource in it, and, one way or another, a person’s life is inextricably connected with the information space. With the information society formation, the problem of information search and processing becomes one of the most urgent. It turns out that despite the abundance and availability of information, it is very difficult to determine its relevance. A lot of effort is spent on developing information retrieval algorithms. Another problem is related to the person’s inability to process large amounts of data. This situation begins to influence not only the education process and professional activity, but also the formation of a person’s personality. A person is "lost" in the information space and gradually loses his/her "I". Algorithms for data analysis come to the rescue, but gradually, instead of giving a person material for thought, they begin to make decisions on their own, and therefore, live life instead of a person. With the advent of Big Data processing algorithms, a new ideological paradigm appears – dataism, which predicts the merger of a person with the general data flow. Originality. The authors make assumptions that the dataistic future is "natural". A lot of works, including in the framework of philosophy, are focused on the problem of "dissolving" a person in the information space and finding ways to overcome it. But, in our opinion, this process is a completely logical continuation of human evolution. Conclusions. Existence of a person as a data flow is not a problem and a threat, but a new dimension of his/her being, and, therefore, requires a careful study and formulation of the main principles of this form of existence.
