Théologien, historien, philosophe, sociologue et homme politique libéral, Ernst Troeltsch (1865-1923) fait partie du groupe des théologiens protestants allemands appelé " Ecole de l'histoire des religions ". Revendiquant l'héritage de Kant et de Schleiermacher, proche de Max Weber et du néo-kantisme de l'Ecole de Bade, Troeltsch est le théoricien classique du néo-protestantisme. Surtout connu en France comme sociologue de la religion, il est redécouvert aujourd'hui comme philosophe et théologien, éclipsé un temps par Barth, l'existentialisme et Heidegger. Les huit essais rassemblés (...) ici sont écrits à l'horizon d'une réflexion sur le religieux marquée par les sciences humaines et sociales et par une conscience accusée de la pluralité des formes de la religion. Troeltsch y dessine un programme qui inscrit délibérément la théologie dans une perspective historique, tout en s'efforçant d'articuler approche empirique et interrogation touchant les jugements de valeur. Il récuse ainsi toute tentative pour faire valoir un domaine théologique réservé : non seulement le christianisme n'est pas la religion dans sa forme achevée ou " absolue ", mais les tentatives pour déterminer une " essence " du christianisme par-delà ses inscriptions socioculturelles diverses devront également être refusées. En désenclavant la réflexion théologique, Troeltsch oblige à redéfinir son objet et son statut : elle ne sera plus explicitation du croire, mais devra esquisser une théorie du christianisme précisant le statut, la fonction et les limites du religieux dans une modernité marquée par la diversification des instances de rationalisation et de légitimité. Ce faisant, son propos tranche avec les discours théologiques dominants dans la seconde moitié du XXe siècle, tant en protestantisme qu'en catholicisme. Et il ouvre à nouveau la question d'une pertinence sociale et culturelle du religieux et du théologique. A l'heure où les paradigmes modernes se trouvent en profonde interrogation sur eux-mêmes et où la question religieuse fait retour - peut-être pour le meilleur mais souvent pour le pire -, la lecture de Troeltsch peut apporter une contribution bienvenue à un ensemble de questions parmi les plus centrales de notre temps. Publiés pour la première fois en français, les textes présentés ici sont accompagnés d'un important appareil de commentaires historiques aidant le lecteur à reconstituer le contexte et la genèse des débats en cause.

How do scientific innovations spread within and across scientific communities? In this paper, we propose a general account of the diffusion of scientific innovations. This account acknowledges that novel ideas must be elaborated on and conceptually translated before they can be adopted and applied to field-specific problems. We motivate our account by examining an exemplary case of knowledge diffusion, namely, the early spread of theories of rational decision-making. These theories were grounded in a set of novel mathematical tools (...) and concepts that originated in John von Neumann and Oskar Morgenstern's Theory of Games and Economic Behavior and subsequently spread widely across the social and behavioral sciences. Introducing a network-based diffusion measure, we trace the spread of those tools and concepts into distinct research areas. We furthermore present an analytically tractable typology for classifying publications according to their roles in the diffusion process. The proposed framework allows for a systematic examination of the conditions under which scientific innovations spread within and across preexisting and newly emerging scientific communities.

The recent wave of generative AI (GAI) systems like Stable Diffusion that can produce images from human prompts raises controversial issues about creatorship, originality, creativity and copyright. This paper focuses on creatorship: who creates and should be credited with the outputs made with the help of GAI? Existing views on creatorship are mixed: some insist that GAI systems are mere tools, and human prompters are creators proper; others are more open to acknowledging more significant roles for GAI, but most (...) conceive of creatorship in an all-or-nothing fashion. We develop a novel view, called CCC (collective-centered creation), that improves on these existing positions. On CCC, GAI outputs are created by collectives in the first instance. Claims to creatorship come in degrees and depend on the nature and significance of individual contributions made by the various agents and entities involved, including users, GAI systems, developers, producers of training data and others. Importantly, CCC maintains that GAI systems can sometimes be part of a co-creating collective. We detail how CCC can advance existing debates and resolve controversies around creatorship involving GAI. (shrink)

This paper examines the adoption of ISO 14001, which is known as the most famous voluntary environmental program. The data of this paper pertain to Korean [Throughout this paper, Korea refers to the Republic of Korea ] firms in manufacturing industries from 1996 to 2011. Event-history modeling to examine firms’ adoption of ISO 14001 finds that both resource-based factors and institutional factors have influenced the diffusion of ISO 14001 in Korea. By exploring time-related effects, I also find that while (...) resource-based factors are important in the early periods of the diffusion, institutional factors become important in the later periods of the diffusion. This confirms the findings of previous studies that a firm’s motivation to adopt organizational policies varies according to different diffusion periods. The paper concludes with a brief discussion of what this study tells us about the institutional context of ISO 14001 in Korea and Asia more broadly. (shrink)

Social media is a prominent communication platform. Its active usage permeates all generations and it is imperative that the platform be fully optimized for knowledge transfer and innovation diffusion. However, there are several considerations regarding platform usage, including media affordances. Social media affordances enable users to interact with the world around them through features of modality, agency, interactivity, and navigation. Previous studies have indicated that social media affordances significantly influence user behavior and usage. However, research exploring the effect of (...) social media affordances on knowledge acquisition and the reduction of decision-making complexities is limited. Therefore, focusing on 179 paddy farmers in Malaysia, this study examined the effect of social media affordances on information quality, knowledge acquisition, and complexity reduction regarding innovation adoption decisions using a quantitative approach. This study’s findings reveal that social media affordances have a significant effect on perceived information quality, knowledge acquisition, and complexity reduction. (shrink)

"Diffusion – Disjunktion – Distanz Erwin Panofskys kulturmorphologische Grundierung oder Nachdenken über Renaissanceand Renascences (1944) Der vorliegende Beitrag skizziert den ersten Teil eines Forschungsentwurfs, in dessenZentrum Erwin Panofskys Artikel Renaissance and Renascences aus dem Jahr 1944steht. Die Analyse des Textes fokussiert Panofskys historische Formel des sog. ›Disjunktionsprinzips‹zur Antikenrezeption und beleuchtet das inliegende Verständniskultureller Prozesse und Zusammenhänge. Der Blick wird auf die kulturtheoretischenImplikationen gelenkt, die in Panofskys Formel enthalten sind. Diese impliziertnämlich eine grundsätzliche Mobilität antiker Kulturelemente. Mit Nähezum ethnologischen Modell (...) der Diffusion wird ein kulturtheoretischer Zugangzu Panofskys Arbeit ermöglicht, der bisher ebenso wenig beachtet wie ideengeschichtlichkontextualisiert wurde. Dabei wird deutlich, dass kulturelle Tradierungsich anhand diffusionistischer Erklärungsmuster mit dem Ziel formiert, einehierarchische Ordnung europäischer (Kultur‑)Epochen am Beispiel der Antikenrezeptionzu postulieren. Der Ansatz zeigt das Potenzial, welches sich im Vergleichdominanter Strömungen der deutschen Ethnologie und der Kunstgeschichte imfrühen 20. Jahrhundert verbirgt. This article sketches the first part of a research project centred on Erwin Panofsky’s article»Renaissance and Renascences« from 1944. The analysis of the text focuses on Panofsky’shistorical formula of the so-called ›principle of disjunction‹ for the reception of antiquity andsheds light on the internal understanding of cultural processes and contexts. The view is directedto the cultural-theoretical implications contained in Panofsky’s formula. This implies afundamental mobility of classical cultural elements. The proximity to the ethnological modelof diffusion enables a cultural-theoretical approach to Panofsky’s work that has so far beenignored, nor has it been contextualized in terms of a history of ideas. It becomes clear thatcultural tradition is formed on the basis of diffusionist explanatory patterns with the aim ofpostulating a hierarchical order of European (cultural) epochs using the example of the receptionof antiquity. The approach shows the potential hidden in the comparison of dominantcurrents in German ethnology and art history in the early 20th century ". (shrink)

Im vorliegenden Artikel wird anhand von detailliertem klinischem Material beschrieben, wie »harte« Ideologien oft als mental-autistische, fetischistische, schalenartige Objekte fungieren, durch die die Kommunikation blockiert wird, aber tief­reichende, archaische osmotisch-diffuse Ängste gelindert werden. Diese Ängste entstehen, weil das Gefühl, als eine abgegrenzte Einheit in Zeit und Raum zu existieren, brüchig ist. »Harte« Ideologien schützen vor diesen Ängsten, greifen aber gleichzeitig sowohl die geistige Gesundheit des Patienten als auch die des Analytikers an und führen zu einem Zustand des psychischen Nirgendwoseins. Menschen, (...) die sich an diese defensiv organisierten »harten Ideologien« halten, sind innerlich häufig aufgewühlt, für sie gibt es keine Balance zwischen ihren psychotischen und nicht-psychotischen Persönlichkeitsanteilen. Darüber hinaus leiden sie an einer autistischen »Verkapselung«, die durch ein starkes Gefühl des Nirgendwoseins gekennzeichnet ist. Sie sind daher rigide auf Themen wie den Schutz der Heimat, der nationalen Grenzen und Identität fixiert und mit den extremen konkreten Maßnahmen beschäftigt, die zu deren Aufrechterhaltung erforderlich sind.

The present study examines the 3-dimensional data of human crania from the Yayoi period (800 BC to AD 250) of the Japanese archipelago by geometric morphometrics to investigate demic diffusion patterns. This is the first study on the Yayoi crania using their 3D data and geometric morphometrics with a much larger number of skeletal remains outside of the Kyushu regions than previous studies. The comparative results between the Jōmon and Yayoi samples show that the Yayoi people not only in (...) the eastern parts but also in the western parts of the archipelago are significantly different from the final Jōmon people and the Yayoi people were not strongly affected by the Jōmon people. A relatively gradual geological cline is also found among the Yayoi population, suggesting that the immigrants from the continental East Asia moved from the western parts to the eastern parts of the archipelago though the causes of the morphological changes are unclear.

The adoption of the codex for literature in the Roman world was one of the most significant developments in the history of the book, yet remains poorly understood. Physical evidence seems to contradict literary evidence from Martial's epigrams. Near-total adoption of the codex for early Christian works, even as the book roll dominated non-Christian book forms in the first centuries of our era, has led to endless speculation about possible ideological motives for adoption. What has been unquestioned is the importance (...) of Christian scribes in the surge of adoption from 300 C.E. onward. This article reexamines the foundation of many theories, the timeline for non-Christian adoption sketched by Roberts and Skeat in their study, The Birth of the Codex, and reevaluates it through the lens of “diffusion of innovations theory” in order to reconcile the evidence and elevate practical considerations once and for all over ideological motives.

Diffusion theory explains in physical terms how materials move through a medium, e.g. water or a biological fluid. There are strong and widely acknowledged grounds for doubting the applicability of this theory in biology, although it continues to be accepted almost uncritically and taught as a basis of both biology and medicine. Our principal aim is to explore how this situation arose and has been allowed to continue seemingly unchallenged for more than 150 years. The main shortcomings of (...) class='Hi'>diffusion theory will be briefly reviewed to show that the entrenchment of this theory in the corpus of biological knowledge needs to be explained, especially as there are equally valid historical grounds for presuming that bulk fluid movement powered by the energy of cell metabolism plays a prominent note in the transport of molecules in the living body. First, the theory's evolution, notably from its origins in connection with the mechanistic materialist philosophy of mid nineteenth century physiology, is discussed. Following this, the entrenchment of the theory in twentieth century biology is analyzed in relation to three situations: the mechanism of oxygen transport between air and mammalian tissues; the structure and function of cell membranes; and the nature of the intermediary metabolism, with its implicit presumptions about the intracellular organization and the movement of molecules within it. In our final section, we consider several historically based alternatives to diffusion theory, all of which have their precursors in nineteenth and twentieth century philosophy of science. (shrink)

Der vorliegende Beitrag setzt die Überlegungen eines Forschungsentwurfs fort, dessen erster Teil im Band 63/2 dieser Zeitschrift erschien. Die historische Formel des sog. ›Disjunktionsprinzps‹ entwickelt Panofsky u.a. in dem 1944 im Kenyon Review erschienenen Artikel Renaissance and Renascences. Die grundsätzliche Mobilität antiker Kulturelemente, die er seiner Formel zuschreibt, impliziert einen bei ihm bisher unbenannten kulturtheoretischen Zugang mit deutlicher Nähe zum ethnologischen Modell der Diffusion. Ausgehend davon entwirft Panofsky mittels einer kulturmorphologischen Vorgehensweise ein transepochales Modell kultureller Tradierung. Dies ermöglicht es (...) ihm, seine Vorstellung einer hierarchischen Gliederung menschlicher (Kultur‑)Epochen am Beispiel der Antikenrezeption zu festigen. Um sich den kulturtheoretischen Implikationen in Panofskys Ausführungen zu nähern, sollen hier jene Stationen beleuchtet werden, die Panofskys intellektuellen Horizont möglicherweise mitgeformt haben – so z.B. die Prägung durch Aby Warburg, der seine Ausbildung in Bonn u.a. unter der Lehre Karl Lamprechts absolvierte. Zum anderen wird Panofskys Argumentation mit den Ideen deutscher Diffusionisten verglichen. Die vergleichende Methode offenbart nicht nur erstmalig deutliche Analogien, sondern zeigt, wie Panofsky mittels Antikenrezeption eine spezifische Vorstellung von der menschlichen Kulturgeschichte vorgibt. The article continues the considerations of a research draft, the first part of which was published in volume 63/2 of this journal. Panofsky develops the historical formula of the socalled ›principle of disjunction‹ in the article ›Renaissance and Renascences‹ published in the Kenyon Review in 1944. The fundamental mobility of ancient cultural elements, which he ascribes to his formula, implies a previously unnamed cultural-theoretical approach with a clear proximity to the ethnological model of diffusion. On this basis, Panofsky uses a cultural morphological approach to design a transepochal model of cultural transmission. This enables him to consolidate the idea of a hierarchical structure of human (cultural) epochs using the example of the reception of antiquity. In order to approach the cultural-theoretical implications in Panofsky’s remarks, those stations that may have shaped Panofsky’s intellectual horizon will be examined – e.g. the influence of Aby Warburg, who completed his education in Bonn under the teachings of Karl Lamprecht, among others. On the other hand, Panofsky’s argumentation is compared with the ideas of German diffusionists. The comparative method not only reveals clear analogies for the first time, but also shows how Panofsky uses the reception of antiquity to provide a specific idea of human cultural history. (shrink)

Threshold models and their dynamics may be used to model the spread of ‘behaviors’ in social networks. Regarding such from a modal logical perspective, it is shown how standard update mechanisms may be emulated using action models – graphs encoding agents’ decision rules. A small class of action models capturing the possible sets of decision rules suitable for threshold models is identified, and shown to include models characterizing best-response dynamics of both coordination and anti-coordination games played on graphs. We conclude (...) with further aspects of the action model approach to threshold dynamics, including broader applicability and logical aspects. Hereby, new links between social network theory, game theory and dynamic ‘epistemic’ logic are drawn. (shrink)

SummaryA kinetic theory of permeability is developed both for the case where the cell membrane is a distinct phase and where it is simply the interface between cell and environment. A general expression for the diffusion current of a substance across the membrane is derived, which depends on two “coefficients of permeability” rather than one. Solubility and adsorption theories of permeability are shown to be special cases of the formulas. The permeability coefficients are expressed in terms of the difference (...) of potential energy of the diffusing substance in the two phases; for a membrane of finite thickness they also involve the thickness, and the diffusion coefficient of the solute in the membrane.

This qualitative study indentifies how corporate responsibility (CR) practices are diffused to companies, as well as the factors that influence this diffusion process. Forest companies, industry associations, non-governmental organizations, and academics in Brazil, Canada, and the United States participated in this interview-based study. Data emerging from a grounded theory approach revealed three factors influencing the diffusion of CR practices to companies: (1) external contextual characteristics, (2) connectors, and (3) experts and expert organizations. These three factors influence each other, (...) meaning that the diffusion process of CR practices is somewhat cyclic. These interactions are usually manifested by companies and expert organizations influencing each other’s actions, being influenced by the external environment, and contributing to the CR trends that are observed in the external environment.

La diffusion des révisions hiéronymiennes des Bibles latines s’est faite notamment à travers les textes liturgiques latins. La présente communication s’intéresse à l’utilisation de l’oeuvre du moine de Bethléem dans les prières des livres liturgiques (missels, sacramentaires et bénédictions pontificales). Elle est centrée sur les citations des livres dits “des petits prophètes”. Si l’oeuvre de Jérôme s’impose progressivement dans la vie liturgique occidentale à partir de la deuxième moitié du VIIe et du VIIIe siècle, plusieurs missels et sacramentaires comportent (...) aussi bien des citations de la révision de Jérôme que de versions des Vieilles latines. C’est notamment le cas de sacramentaires irlandais de la fin du VIIe siècle et du missel gallican dit Missale Gothicum, datant des années 700. À cette époque, l’oeuvre de Jérôme n’est donc pas encore utilisée par la liturgie comme un ensemble unifié. La citation et l’allusion aux anciennes traductions latines persiste même dans la péninsule ibérique et la liturgie mozarabe jusqu’au XIIe siècle. Une étude détaillée des allusions au livre II de Jonas montre que des morceaux de versets issus des Vieilles latines se sont maintenus pendant tout le Moyen-Âge dans des livres ayant recours à la Vulgate, peut-être parce qu’ils étaient passés dans la culture biblique collective. Cet article souligne donc la nécessité d’une analyse détaillée, livre liturgique par livre liturgique, pour étudier les citations de la Bible dans la liturgie latine, car une même pièce liturgique peut emprunter à plusieurs traductions différentes.

This article presents a new hypothesis on the origin of life on Earth. According to this hypothesis, life arose within the limits of a particular material system representing a set of specific local environments integrated by a common circulating liquid medium where relatively short RNA molecules, viroid-like particles, are replicated with great accuracy. In each of the local environments, the synthesis of certain substances that are required for accurate replication and survival of the RNAs is carried out. The system, which (...) we called “diffuse organism,” is, in essence, a very rough and bulky analog of the structural-functional organization of the cell’s biosynthetic machinery. The diffuse organism was an organismal and evolving system at the same time. It seems that only such a system that has emerged in the only specimen as a result of a set of chance events operating under a system of universal physical and chemical laws was able to give rise to life and evolution by means of biological selection. The outlined scenario for the origin of life allows us to narrow down the still insuperable gap between prebiological chemistry and the first living systems without devising conceptions unrelated to the realities of life.

In previous work the author was able to derive the Schrödinger equation by an analytical approach built around a physical model that featured a special diffusion process in an ensemble of particles. In the present work, this approach is extended to include the derivation of the Dirac equation. To do this, the physical model has to be modified to make provision for intrinsic electric and magnetic dipoles to be associated with each ensemble particle.

In 1965, the discovery of a new type of uniform radiation, located between radiowaves and infrared light, was accidental. Known today as Cosmic Microwave background, this diffuse radiation is commonly interpreted as a fossil light released in an early hot and dense universe and constitutes today the main ’pilar’ of the big bang cosmology. Considerable efforts have been devoted to derive fundamental cosmological parameters from the characteristics of this radiation that led to a surprising universe that is shaped by at (...) least three major unknown components: inflation, dark matter and dark energy. This is an important weakness of the present consensus cosmological model that justifies raising several questions on the CMB interpretation. Can we consider its cosmological nature as undisputable? Do other possible interpretations exist in the context of other cosmological theories or simply as a result of other physical mechanisms that could account for it? In an effort to questioning the validity of scientific hypotheses and the under-determination of theories compared to observations, we examine here the difficulties that still exist on the interpretation of this diffuse radiation and explore other proposed tracks to explain its origin. We discuss previous historical concepts of diffuse radiation before and after the CMB discovery and underline the limit of our present understanding. (shrink)

SummaryThe transmission of ideas about sovereignty and its related practices from one time, place, or intellectual context to another is sometimes characterised as a process of ‘diffusion’ or even ‘contagion’. Intellectual historians may use such metaphors but the explanations they provide are historical, not scientific. Sovereignty was transmitted when European states brought their forms of government to other peoples and when those peoples embraced such forms in declaring their independence from imperial rule. It was also transmitted when the idea (...) of sovereignty was itself transformed in the course of these and other historical passages. In Foundations of Modern International Thought, David Armitage explores some of these historical passages, the outcome of which he sees as the world of sovereign states that defines the modern period and the disappearance of which would signal its end. In doing so, he illuminates the larger enterprise of writing the history of international thought or, as he prefers to call it, international intellectual history, inviting reflection on its relationship to other kinds of historical inquiry and the opportunities and dangers it poses.

The diffusion of technology in the US has taken place in an environment of both regulation and free enterprise. Each has been subject to manipulation by doctors and medical administrators that has fostered unprecedented ethical dilemmas and legal challenges. Understanding these developments and historical precedents may allow a more rational diffusion policy for medical technology in the future.

In Everett’s many-worlds interpretation, where quantum measurements are seen as decoherence events, inexact decoherence may let large worlds mangle the memories of observers in small worlds, creating a cutoff in observable world measure. I solve a growth–drift–diffusion–absorption model of such a mangled worlds scenario, and show that it reproduces the Born probability rule closely, though not exactly. Thus, inexact decoherence may allow the Born rule to be derived in a many-worlds approach via world counting, using a finite number of (...) worlds and no new fundamental physics. (shrink)

Social-bots-mediated information manipulation is influencing the public opinion environment, and their role and behavior patterns in news proliferation are worth exploring. Based on the analysis of bots' posting frequency, influence, and retweeting relationship, we take the diffusion of The New York Times' coverage of Xinjiang issue on the overseas social platform Twitter as an example and employ the two-step flow model. It is found that in the role of second-step diffusion, unlike posting news indiscriminately in first-step diffusion, (...) social bots are more inclined to postcontroversial information in second-step diffusion; in terms of diffusion patterns, although social bots are more engaged in first-step diffusion than in second-step diffusion and can trigger human users to retweet, they are still inferior to humans in terms of influence.

According to the Welfare Diffusion Objection, we should reject Prioritarianism because it implies the ‘desirability of welfare diffusion’: the claim that it can be better for there to be less total wellbeing spread thinly between a larger total number of people, rather than for there to be more total wellbeing, spread more generously between a smaller total number of people. I argue that while Prioritarianism does not directly imply the desirability of welfare diffusion, Prioritarians are nevertheless implicitly (...) committed to certain principles for comparing different-number populations which, together with the Prioritarian same-person axiology, imply the desirability of welfare diffusion.

We take a logical approach to threshold models, used to study the diffusion of opinions, new technologies, infections, or behaviors in social networks. Threshold models consist of a network graph of agents connected by a social relationship and a threshold value which regulates the diffusion process. Agents adopt a new behavior/product/opinion when the proportion of their neighbors who have already adopted it meets the threshold. Under this diffusion policy, threshold models develop dynamically towards a guaranteed fixed point. (...) We construct a minimal dynamic propositional logic to describe the threshold dynamics and show that the logic is sound and complete. We then extend this framework with an epistemic dimension and investigate how information about more distant neighbors’ behavior allows agents to anticipate changes in behavior of their closer neighbors. Overall, our logical formalism captures the interplay between the epistemic and social dimensions in social networks. (shrink)
