A gas in a box is perhaps the most important model system studied in thermodynamics and statistical mechanics. Usually, studies focus on the gas, whereas the box merely serves as an idealized confinement. The present article focuses on the box as the central object and develops a thermodynamic theory by treating the geometric degrees of freedom of the box as the degrees of freedom of a thermodynamic system. Applying standard mathematical methods to the thermody- namics of an empty box allows (...) equations with the same structure as those of cosmology and classical and quantum mechanics to be derived. The simple model system of an empty box is shown to have interesting connections to classical mechanics, special relativity, and quantum field theory. (shrink)

The special composition question, which asks under which conditions objects compose a further object, establishes a central debate in modern metaphysics. Recent successes of inductive metaphysics, which studies the implications of the natural sciences for metaphysical problems, suggest that insights into the SCQ can be gained by investigating the physics of composite systems. In this work, I show that the minus first law of thermodynamics, which is concerned with the approach to equilibrium, leads to a new approach to the SCQ, (...) the thermodynamic composition principle : Multiple systems in thermal contact compose a single system. This principle, which is justified based on a systematic classification of possible mereological models for thermodynamic systems, might form the basis of an inductive argument for universalism. A formal analysis of the TCP is provided on the basis of mereotopology, which is a combination of mereology and topology. Here, “thermal contact” can be analyzed using the mereotopological predicate “self-connectedness”. Self-connectedness has to be defined in terms of mereological sums to ensure that scattered objects cannot be self-connected. (shrink)

Explaining the emergence of stochastic irreversible macroscopic dynamics from time-reversible deterministic microscopic dynamics is one of the key problems in philosophy of physics. The Mori-Zwanzig projection operator formalism, which is one of the most important methods of modern nonequilibrium statistical mechanics, allows for a systematic derivation of irreversible transport equations from reversible microdynamics and thus provides a useful framework for understanding this issue. However, discussions of the MZ formalism in philosophy of physics tend to focus on simple variants rather than (...) on the more sophisticated ones used in modern physical research. In this work, I will close this gap by studying the problems of probability and irreversibility using the example of Grabert’s time-dependent projection operator formalism. This allows to better understand how general proposals for understanding probability in statistical mechanics, namely quantum approaches and almost-objective probabilities, can be accomodated in the MZ formalism. Moreover, I will provide a detailed physical analysis, based on the MZ formalism, of various proposals from the philosophical literature, such as Robertson’s theory of justifying coarse-graining via autonomous macrodynamics, Myrvold’s problem of explaining autonomous macrodynamics, and Wallace’s simple dynamical conjecture.

This article explores the discursive uses of a self-quotation in adolescent talk. The self-quotation uses the quotative marker be + like to convey or project bold statements as part of a larger narrative. We will demonstrate how the preface leading up to the self-quotation is designed as hard to counter, and instructs the hearer how to understand what comes next. The self-quotation, on the other hand, constitutes the assessment as a `mere characterization' that provides the speaker with a number of (...) opportunities for testing the proposed view. Speakers are thus able to bolster potentially controversial views against refutation while also giving them a preliminary status. These features make for an interesting conversational resource that enables speakers and recipients to engage in a collaborative process of putting potentially bold statements to the test. (shrink)

In the United States, final amendments to the Federal Policy for the Protection of Human Subjects (“the Common Rule”) were published on January 19, 2017, and they will take effect on January 21, 2019. One of the most widely discussed provisions is that for the first time, federal regulations governing research with humans authorize the use of broad consent for future, unspecified research on individually identifiable biospecimens and associated data. Many questions have been raised about broad consent, including what effect (...) it will have on research and whether it adequately protects the interests of research participants.There are lessons to be learned for the U.S. and other countries by looking to countries that already have experience with broad consent for biobank collection and with the storage and subsequent use of the biospecimens and data. This article describes how broad consent works in five countries—Canada (in Quebec), Israel, Nigeria, Taiwan, and the United Kingdom—and with different types of biobanks: national biobanks, federated biobanks, and regional biobanks. Evaluating the provisions and challenges of the broad consent approaches in these countries can inform policies for this increasingly used approach to biobank regulation. (shrink)

SummaryIntense, sustained nursing lengthens inter-birth intervals and is causally linked with low natural fertility. However, in traditional settings, the effects of such nursing on fertility are difficult to disentangle from those of nutrition. Results from an prospective, direct observational study of reproductive function in well-nourished Amele women who nurse intensively and persistently but who also have high fertility are here presented. Endocrine measures show that ovarian activity resumes by median 11·0 months postpartum. Median duration of postpartum amenorrhoea is 11·3 months, (...) time to next conception is 19·0 months, and the inter-birth interval is 28·0 months. Average life time fertility is 6·8. High fertility in Amele women is due both to refractoriness of reproductive function to suckling stimuli, and to maintenance of equivalent age-specific fertility rates across the reproductive life span.

This narrative review of the literature assessed whether regular physical exercise and sleep patterns, fasting and autophagy, altogether can be an adequate strategy for achieving healthy longevity and well-being within different stage of life. There are a large number of studies dealing with well-being and healthy longevity; however, few of them have given us a specific formula for how to live long and healthy. Despite all the advances that have been made to create adequate physical exercise programs, sleep patterns or (...) nutritional protocols, the relation between different types of fasting, nutritional supplementation as well as regular physical exercise and sleep patterns have not yet been satisfactorily resolved to cause the best effects of autophagy and, therefore, well-being and healthy longevity. In this way, future studies should clarify more efficiently the relationship between these variables to understand the association between regular physical exercise, sleep patterns, fasting and autophagy for healthy longevity and well-being.

Anonymous commentary on Jaimini's Mīmāṃsāsūtra, aphoristic work setting forth the tenets of the Mīmāṃsā school in Hindu philosophy.

Looking at the recent spate of claims about “fake news” which appear to be a new feature of political discourse, I argue that fake news presents an interesting problem in epistemology. Te phenomena of fake news trades upon tolerating a certain indiference towards truth, which is sometimes expressed insincerely by political actors. Tis indiference and insincerity, I argue, has been allowed to fourish due to the way in which we have set the terms of the “public” epistemology that maintains what (...) is considered “rational” public discourse. I argue one potential salve to the problem of fake news is to challenge this public epistemology by injecting a certain ethical consideration back into the discourse. (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)

Tradicionalmente se ha entendido que la mejor teoría de la responsabilidad extracontractual es aquella que mejor explica los rasgos centrales de la práctica. En este sentido, los defensores de las teorías deontológicas, basadas en principios de justicia, han rechazado el poder explicativo del análisis económico del derecho. Han sostenido que no logra reconstruir la práctica dando sentido a sus conceptos centrales, ni al modo en que están relacionados. Por lo tanto, no puede explicar la pauta de inferencias que llevan a (...) un juicio de responsabilidad. En este trabajo me propongo mostrar que ambas teorías son capaces de explicar aspectos diferen- tes de la práctica. En contra de lo que se asume generalmente, el análisis económico del derecho y las teorías deontológicas no son teorías rivales, sino compatibles, puesto que tienen por objeto responder a preguntas distintas.

In De schijn-élite van de valse munters laat Martin Bosma, Tweede-Kamerlid voor de PVV, zien dat de anti-immigratiepolitiek van die partij in lijn ligt met het socialisme van Jacques de Kadt en Willem Drees. Hij deconstrueert het multiculturalisme van Nieuw Links, dat daarna kwam, en wijst erop dat het blind was voor steeds nijpender immigratie- en criminaliteitskwesties. In de eigen ideologie van de PVV die Bosma vervolgens tentoonspreidt, zijn echter eveneens de nodige witte vlekken aan te wijzen.

So Hall and Geldart's text and critical note. The latter needs a correction and an addition: R gives (so, too, ΣR, which has ; γ is found only in B and the Aldine edition, R and V omit it. What is the object of Van Leeuwen says ‘mente suppl.xwhich seems to me inconsequent if not nonsensical. Starkie, printing a dash after the word, notes ‘as the sentence is interrupted by Philocleon, it is impossible to know what was meant to be (...) the object of this verb’. This does not seem very satisfactory. Rogers apparently takes the verb as used absolutely and translates ‘you'll strike by and by’. Coulon, not unnaturally dissatisfied with these explanations, reads and translates ‘tu vas te faire lapider’, adding a note ‘on jetait des pierres aux fous; cf. Otseaux 524’. Starkie also mentions this possibility and attributes its origin to the scholiast—wrongly, for the gloss shows that the scholiast did not take as meaning ‘will be pelted as a madman’. In any case all this is very far-fetched. And there is a further point: the strange future active, is found elsewhere only at line 222 of this same play and nowhere else in Greek. It is therefore rash to postulate an entirely unparalleled middle form of this, and that, too, in a passive sense. Had he intended this meaning Aristophanes would surely have written. (shrink)

Si bien es cierto que la técnica es una de las dimensiones fundamentales de la condición humana, sólo contemporáneamente ha adquirido el rango de característica “epocal” por excelencia: vivimos en la “era de la técnica”. De ahí que la mayoría de los principales filósofos de nuestro tiempo le hayan prestado una muy especial atención. Su penetrante mirada busca, detrás de lo más tópico y visible, lo más profundo. Y, por eso, lo que ellos han visto, o entrevisto, ha de sernos (...) de gran ayuda para entender mejor la encrucijada en que nos encontramos, así como para repensarnos una vez más a nosotros mismos. La oportunidad y la singularidad de esta obra consisten en sintetizar, exponer y comentar las ideas de José Ortega y Gasset, Martin Heidegger, Jan Patocka, Jacques Ellul, Hannah Arendt, Hans Jonas, Jürgen Habermas y Peter Sloterdijk sobre la configuración técnica (y tecnológica) del mundo. Como, además, la cuestión de la técnica es nuclear en todos estos autores, tenemos con ella una buena puerta de acceso a cada una de sus respectivas filosofías. (shrink)

Three experiments are reported which show that in certain contexts subjects reject instances of the valid modus ponens and modus tollens inference form in conditional arguments. For example, when a conditional premise, such as: If she meets her friend then she will go to a play, is accompanied by a conditional containing an additional requirement: If she has enough money then she will go to a play, subjects reject the inference from the categorical premise: She meets her friend, to the (...) conclusion: She will go to a play. Other contexts suppress the conditional fallacies. The first experiment demonstrates the effects of context on conditional reasoning. The second experiment shows that the inference suppression disappears when the categorical premise refers to both of the antecedents, such as: She meets her friend and she has enough money. In this case, subjects make both the valid inferences and the fallacies, regardless of the contextual information. The third experiment establishes that when subjects are given general information about the duration of a situation in which a conditional inducement was uttered, such as: If you shout then I will shoot you, they reject both the valid inferences and the fallacies. The results suggest that the interpretation of premises plays an even more central role in reasoning than has previously been admitted. Trois expériences montrent que dans certains contextes les sujets rejettent des instances valides de modus ponens et de modus tollens dans des énoncés conditionnels. Par exemple, quand une prémisse conditionnelle comme: Si elle rencontre son ami, alors elle ira jouer, est accompagnée par une phrase contenant une condition supplémentaire: Si elle a assez d'argent, alors elle ira jouer, les sujets rejettent l'inférence liant la prémisse catégorielle: Elle rencontre son ami, à la conclusion: Elle ira jouer. D'autres contextes éliminent également les inférences conditionnelles fallacieuses. La premiére expérience démontre l'effet du contexte sur la raisonnement conditionnel. La deuxiéme expérience montre que la suppression de l'inférence disparait quand la prémisse catégorielle fait référence aux deux antécédants, comme: Elle rencontre son ami et elle a assez d'argent. Dans ce cas, les sujets font aussi bien les inférences valides et fallacieuses, quelle que soit l'information contextuelle. La troisiéme expérience établit que quand l'on donne aux sujets des informations générales à propos de la durée d'une situation dans laquelle une conditionnelle a été prononcée, comme Si tu cries, alors je te tire dessus, ils rejettent autant les inférences valides que les inférences fallacieuses. Ces résultats suggèrent que l'interprétation des prémisses joue un rŏle encore plus central dans le raisonnement que l'on admettait auparavant. (shrink)

Originally the Adoro te devote was not a liturgical hymn but a prayer, probably intended by Thomas Aquinas for personal use when attending mass. Quoting the at present most reliable version of the poem, the author studies Adoro te devote from the angle of transformation: poetic, Eucharistic and mystic or eschatological transformation. Structure and form are analysed, and a number of themes discussed: two alternative interpretations of adoration, several concepts of truth intended in the poem, the good thief and doubting (...) Thomas as symbols of moral and spiritual imperfection, and living in connection, in union with God. (shrink)

Leadership plays an essential part in creating competitive advantage and well-being among employees. One way in which formal leaders can deal with the variety of responsibilities that comes with their role is to share their responsibilities with team members (i.e., shared leadership). Although there is abundant literature on how high-quality peer leadership benefits team effectiveness (TE) and well-being, there is only limited evidence about the underpinning mechanisms of these relationships and how the formal leader can support this process. To address (...) this lacuna, we conducted an online survey study with 146 employees from various organizations. The results suggest that an empowering leadership style of the formal leader is associated with higher perceived peer leadership quality (PLQ) on four different leadership roles (i.e., task, motivational, social, and external leader). In addition, formal leaders who empower their team members are also perceived as better leaders themselves. Moreover, the improved PLQ was in turn positively related to TE and work satisfaction, while being negatively related to burnout. In line with the social identity approach, we found that team identification mediated these relationships. Thus, high-quality peer leaders succeeded in creating a shared sense of “us” in the team, and this team identification in turn generated all the positive outcomes. To conclude, by sharing their lead and empowering the peer leaders in their team, formal leaders are key drivers of the team’s effectiveness, while also enhancing team members’ health and well-being.
