With the assumption of inactivation of small traits in bacteriophages “chromosomes” by ultraviolet irradiation the probability of multiplicity reactivation of irradiated phages is calculated. The result appears to be in agreement with the experimental results ofDulbecco.In the mathematical treatment of the problem a distinction is made between ordinary genes, with probability of inactivation negligible relative to the probability of inactivation of the whole phage, and a few vulnerable centers or genes whose probability of inactivation is not negligible. The hypothesis of (...) the existence of vulnerable centers appears necessary in order to explainDulbecco's experimental results.Postulant que de petites sections des „chromosomes” du bactériophage sont inactivés par l'irradiation ultraviolette, on a calculé la probabilité de réactivation par infection multiple des bactériophages traités par les rayons ultraviolets. Les résultats obtenus s'accordent avec les résultats expérimentaux de M.Dulbecco.Dans la tractation mathématique des problèmes une distinction a été faite entre les gènes ordinaires — dont la probabilité d'inactivation prise individuellement peut Être négligée relativement à la probabilité d'inactivation du phage entier — et quelques centres vulnérables ou gènes dont la probabilité d'inactivation ne pourrait Être négligée.L'hypothèse de l'existance des centres vulnérables s'est démontrée nécessaire à l'explication des résultats expérimentaux de M.Dulbecco.Die Wahrscheinlichkeit der Reaktivation durch multiplen Infektionen ist unter Voraussetzung, dass die Ultraviolett-Bestrahlung kleine Teile der Bakteriophagenchromosomen inaktiviert, berechnet. Das Ergebnis entspricht den experimentellen ResultatenDulbecco's.In der mathematischen Behandlung des Problems ist ein Unterschied gemacht worden zwischen gewöhnlichen Genen — wovon jeder eine geringe Wahrscheinlichkeit der Inaktivierung hat, in Bezug auf die Wahrscheinlichkeit der Inaktivierung der ganzen Bakteriophage — und einige verletzbare Stellen oder Genen, wovon die Wahrscheinlichkeit der Inaktivierung grössenordnungsmÄssig höher liegt. Die Hypothese über die verletzbaren Stellen war notwendig um die experimentellen ResultateDulbecco's zu erklÄren. (shrink)

In order to explain several discrepancies between the gene-recombination phenomena in phages and in higher organisms, we assume that theT 2 phage, after entering the bacterium, divides in three parts corresponding to the three “chromosomes' whichHershey andRotman have traced in this phage. The three parts are supposed to be able to divide further by rupture or by the action of other “chromosome fragments”. Each fragment is supposed able to reproduce inside the bacterium as a more or less independent unit and (...) before lysis of the bacterium the various parts are assumed to reunite in complete sets of genes each forming a new phage.After discussing the experimental facts supporting these assumptions, we show that the assumptions are in perfect agreement with the theory of the symbiosis of genes, a theory which seems necessary in order to explain the ability of the “chromosome-fragments” to reunite into complete phages.Also the problems arising with respect to the sexual reproduction in bacteria is discussed under the point of view of the symbiosis theory. The assumption is made that the hereditary material is transduced from bacterium to bacterium by ultramicroscopic virus-like particles “genophores”. In several lysogenic bacteria the genophores are supposed still able to act as parasites instead of symbiontes towards some other sensitive bacteria. The experimental facts supporting this assumption are analyzed, and new experimental tests suggested. (shrink)

An interpretive system for the IBM 704 computer permitting interpretation of the genetic pattern of a numeric symbioorganism as a game strategy has been developed. Selection for best performance in a simple game has been applied in a preliminary experiment. An objective method to measure the quality of a game played is described. The results presented in the article show a small but significant improvement of game quality during a period of 2300 generations.The general characteristics of the phenomena observed are (...) similar to those of preceding evolution experiments . However, a startling infection process caused by a parasite whose behaviour was influenced by the game competition is described. The parasite never developed an independent game strategy to any degree of efficiency and was entirely dependent on its host organism for game competitions with, and transmission of the infection to, uninfected hosts.The consequences of substituting the reproduction and mutation rules used in the preceding evolution experiments are discussed. Particularly, the use of rules applying the reproduction pattern ofDNA-molecules is considered, and the theoretic aspects of symbiogenetic evolution experiments based onDNA-norm are discussed. A few inferences concerning the origin and history of terrestrial life suggested by the results of the symbiogenesis experiments are presented.Ein interpretierendes System für die IBM 704 Rechenmaschine, dass Interpretation des genetischen Modells von einem numerischen Symbio-organismus wie eine Spiel Strategie, erlaubt, wurde entwickelt. Eine Forführung für Fähigkeit in einem einfachen Spiel wurde angewandt in einem preliminarisches Experiment. Eine objektive Methode zur Messung der Qualität des betreffenden Spiels wurde beschrieben. Die in dem Artikel angegebenen Resultate zeigen eine kleine, aber bedeutende Verbesserung der Spiel-Qualität während einr Periode von 2300 Generationen.Die allgemeinen Kennziechen von den beobachteten Phänomenen sind denen von vorhergehenden Evolutions-Experimenten ähnlich . Jedoch, ein überraschender Infektions-Prozess, verursacht durch einen Parasit, wessen Verhalten beinflusst wurde durch die Spiel-Konkurrenz, wurde beschrieben. Der Parasit entwickelte niemals eine unabhängige Spiel-Strategie zu irgendeinem Masze von Fähigkeit und war ganz abhängig von seinem Gastherr-Organismus für Spiel-Konkurrenz mit, und Überbringung von der Infektion auf, uninfektierte Gäste.Die Folgerungen von dem Ersetzen der Fortpflanzung und Mutations-Regeln , angewandt in vorhergehenden Evolutions-Experimente wurden besprochen. Besonders der Gebrauch von Regeln welche das FortpflanzungsModell von DNA-Molekülen anwenden wurde betrachtet, und die theorethischen Aspekte von Symbiogenetischen Evolutions-Experimenten basiert auf DNA-Norm wurden besprochen. Einige Schlussfolgerungen in Bezug auf die Entstehung und Geschichte von dem Erdenleben suggeriert durch die Resultate von den Symbiogenese-Experimenten wurden gezeigt. (shrink)

An interaction between the ways morality and society develop in the face of the challenges they are exposed to seems consistent with empirical evidence. However, within this frame man's instinct of self preservation and his individualism seem to play an important part. The former by its influence on the evolution of what I refer to as 'our social morality'. The latter by finding its expression in conservative and radical ideologies whose political confrontation appears to give rise to an evolutionary develop (...) ment. The paper draws attention to the fact that in the face of contemporary challenges the evolutionary development of our morals may determine whether the corresponding evolutionary development of our societies will approach the patterns of those of insects, or whether our highly developed individual istic traits will result in new moral trends creating a society which is better suited to the present characteristics of humankind. It is also argued that the present growth of international organizations for cooperation and peaceful co-existence should make it possible to build a society worthy of the human race, but that it could be done only if we are able to develop a sufficient sense of responsibility to deliberately keep over-consumption and human population within a natural balance.

Les Prolegomenes a la Philosophie de Platon sont un manuel d'ecole neoplatonicien. Il s'inspire d'un modele dont Proclus a du etre l'auteur, mais l'origine de ce texte est presque surement alexandrine et doit dater de la premiere moitie du Vle siecle. Cette oeuvre est essentielle pour comprendre comment etait diffuse l'enseignement platonicien, et pour mieux saisir le mouvement des idees de l'Antiquite finissante. Dans une importante introduction, L. O. Westerink a retrace l'histoire de l'ecole d'Alexandrie et celle du genre litteraire (...) de ces introductions a Platon et a Aristote. (shrink)

Modern scholars have been concerned with the hostility shown to Alexander by the Hellenistic schools of philosophy. Two literary portraits have been distinguished, the Peripatetic and the Stoic, the former deriving from Theophrastus' book on Callisthenes, or starting with this work the Peripatetics worked out a theory of and applied it to Alexander, in order to belittle his achievements. It was a case of giving sophisticated expression to the kind of crude resentment expressed by Demades.

The locus classicus for Plutarch's own views on his methods is in the Alexander He has begun by asking for the indulgence of his readers if they do not find all the exploits of Alexander and Caesar recounted by the biographer or if they discover him not reporting some famous incident in detail (); and he goes on to compare his own search for evidence which will indicate the kind of soul, with the activity of the painter, who, in order (...) to create a likeness, concentrates on the eyes and pays little attention to the other parts. Commentators and critics have been right to take this as a key text for the purpose of understanding Plutarch's attitude towards his biographical work; nevertheless there are other passages in the Lives where we can at least glimpse his attitude to his subject, and we can only see the Alexander-remarks in correct perspective if we take these other passages into account. I propose therefore, starting with the Alexander, to see how far these critical remarks apply to Plutarch's theory and practice elsewhere in the Lives. (shrink)

According to the Ars Amatoria the notorious rape took place on the occasion of a primitive dramatic entertainment staged in a theatre, in which the seats and furnishings were also primitive. There is no time for a description of the arts of the performers—a tibicen and a ludius—before the Romans, impatient for action, receive their signal from Romulus. Nor is there any mention of a god in whose honour the entertainment had been provided.

Tuberculosis (TB) is a potentially fatal infectious disease that, in Aotearoa New Zealand (NZ), inequitably affects Asian, Pacific, Middle Eastern, Latin American, and African (MELAA), and Māori people. Medical research involving genome sequencing of TB samples enables more nuanced understanding of disease strains and their transmission. This could inform highly specific health interventions. However, the collection and management of TB isolate samples for research are currently informed by monocultural biomedical models often lacking key ethical considerations. Drawing on a qualitative kaupapa (...) Māori–consistent study, this paper reports on preliminary discussions with groups of Māori, Pacific, and Afghan people in NZ, whose communities have been harmed by TB and TB stigma. Participants’ discussions highlight key concerns and meanings that ought to inform the development of guidelines and a more robust consultative process for the governance of how TB isolate samples are collected and used both retrospectively and in future research. We argue for ethical processes to be culturally nuanced and community-generated, flexible and meaningful, and situated in relation to the physical and symbolic effects of TB. We discuss the significance of Indigenous data sovereignty, rights, and kāwanatanga (governorship) in shaping a multicultural data sovereignty model. (shrink)

De Interpretatione is among Aristotle's most influential and widely read writings; C. W. A. Whitaker presents the first systematic study of this work, and offers a radical new view of its aims, its structure, and its place in Aristotle's system. He shows that De Interpretatione is not a disjointed essay on ill-connected subjects, as traditionally thought, but a highly organized and systematic treatise on logic, argument, and dialectic.
