The hydrolyzing actions of various preparations of the adult eel were studied on ten esters in the usual way. The results are presented in the form of curves for the relative actions and in a table for the absolute actions obtained in one complete experiment. The separation of the enzyme material in some cases into an active portion and a co-enzyme, the mixture showing greater actions on some esters than the sums of the individual actions, is described and discussed.

When assessing any security technology which impacts upon privacy, whether this constitutes a new technology or the novel application of existing technologies, we should do so by examining the combined effect of all security interventions currently employed within a society. This contrasts with the prevailing system whereby the impact of a new security technology is predominantly assessed on an individual basis by a subjective balancing of the security benefits of that technology against any reductions in concomitant rights, such as privacy and liberty. I contend that by continuing to focus on the individual effect, as opposed to the combined effects, of security technologies within a society the likelihood of sleep-walking into (or indeed waking-up in) an absolute surveillance society moves from a possible future to the logically inevitable future. This conclusion is based on two underlying assertions. Firstly that assessing a technology often entails a judgement of whether any loss in privacy is legitimised by a justifiable increase in security; however one fundamental difference between these two rights is that privacy is a finite resource with identifiable end-states (i.e. absolute privacy through to the absolute absence of privacy) whereas security does not have two finite end-states (while there exists the absolute absence of security, absolute security is an unobtainable yet desired goal). The second assertion, which relies upon the validity of the first, holds that one consequence of absolute security being unobtainable yet desirable is that new security interventions will continuously be developed, each potentially trading a small measure of privacy for a small rise in security. Examined individually each intervention may constitute a justifiable trade-off. However this approach of combining interventions in the search for ever greater security will ultimately reduce privacy to zero.

Abstract In the presented text the author points out to anthropological as well as axiological foundations of the boxing fight from the viewpoint of Hegel’s philosophy. In the genial idealist’s views it is possible to perceive the appreciation of the body, which constitutes a necessary basis for the man’s physical activity, for his work oriented towards the self-transformation and the transformation of the external world, as well as for rivalry and the hand-to-hand fight. While focusing our attention on the issue of rivalry and on the situation of the fight - and regarding it from the viewpoint of the master - slave theory (included in the phenomenology of spirit), it is possible to proclaim that even a conventionalised boxing fight - that is, restricted by cultural and sports rules of the game - has features of the fight to the death between two Hegelian forms of selfknowledge striving for self-affirmation and self-realisation. In the boxing fight, similarly as in the above mentioned Hegelian theory, a problem of work and of the development of the human individual (that is, of the subject, self-knowledge, the participant of the fight) appears. There appears also a prospect of death as a possible end of merciless rivalry. The fight revalues the human way in an important way, whereas the prospect for death, the awareness of its proximity, the feeling that its close and possible, saturates the life with additional values. It places the boxer, just like every subject fighting in a similar or a different way, on the path towards absolute abstraction - that is, it brings him closer to his self-fulfilment in the Absolute, to the absolute synthesis. The Hegelian viewpoint enables also to appreciate the boxing fight as a manifestation of low culture (being in contrast with high culture), to turn attention to the relations which - according to Hegel - take place between the Absolute and the man, as well as to show which place is occupied by the subject both in the process of the Absolute’s self-realisation and in the German thinker’s philosophical system. Independently of the dialectical, simultaneously pessimistic and optimistic overtone of considerations connected with the very boxing fight (regarding destruction and spiritualisation on a higher level), it is possible to perceive farreaching appreciation of the human individual in Hegel’s philosophy since the Absolute cannot make its own self-affirmation without the individual, without the human body, without the fight aimed at the destruction of the enemy and without the subjective consciousness and the collective consciousness which appear thanks to this fight. Thus, it is justified to suppose that the foundation of the whole Hegel’s philosophy is constituted by anthropology and that in the framework of this anthropology a special role is played by the fight and by work, which changes the subject and his(her) environment. Admittedly Hegel does not emphasise it explicitly, nevertheless his views (with their centre, which, according to Hegel himself and his interpreters, is constituted by the Absolute) have, as a matter of fact, an anthropocentric character and the main source of the subject’s development is the struggle which, irrespectively of its result, always primarily leads to the destruction or even to the death of one of the sides, just like in the boxing fight. However, it is also a germ of the positive re-orientation of the subject, the beginning and a continuation of that what the phenomenology of the spirit describes as a movement towards absolute abstraction.

Abstract According to a well-known problem in climate ethics, individual actions cannot be wrong due to their impact on climate change since the individual act does not make a difference. By referring to the practical interpretation of the categorical imperative, the author argues that certain actions lead to a contradiction in conception in light of the climate crisis. Universalizing these actions would cause foreseeable climate impacts, making it impossible to pursue the original maxim effectively. According to the practical interpretation, such actions are morally wrong. The wrongness of these actions does not depend on making a difference, rather these actions are wrong because they make it impossible for others to act accordingly. Thus, apart from imperfect duties, for which has been argued convincingly elsewhere (Henning 2016; Alberzart 2019), we also have perfect duties to refrain from certain actions in the face of the climate crisis.

15 catalogues produced in the eighties and 12 catalogues of the sixties-seventies have been used to assess the consistency of the FK5 system with observations in the declination zone from −30° to 30°. Positions of the FK4-based catalogues have been transformed at the equinox and equator J2000.0. Classical δ-dependent and α-dependent systematic differences (Cat-FK5) have been formed for individual instrumental systems of the catalogues by a method close to the classical Numerical Method. The weighted mean instrumental systems for the two subsets of catalogues centered at the epochs 1970 (MIS 60–70) and 1987 (MIS 80) and for all types of systematic differences have been constructed. The mean errors of the total systematic differences in α and δ have been estimated as 14 mas and 21 mas, respectively, for the catalogues of the 60-70ies, and 10 mas in both α and δ for the catalogues of the 80ies.It has been found that the mutual consistency of individual instrumental systems of catalogues of the 80ies with respect to δ-dependent systematic differences is superior by the factor 1.5 comparing with the catalogues of 60-70ies, while the consistency of both catalogue selections with respect to α-dependent systematic differences is comparable. Random accuracy of the FK5 positions and proper motions at the epochs under analysis has been assessed as close to expected from the formal considerations. Actual systematic discrepancies of the FK5 with observations at the respective epochs have been detected. For systematic differences δαδ cosδ and δδδ, the absolute deviations of the MIS 80 are, in general, within 40 mas, those of the MIS 60-70 are within 30 mas. For systematic differences δαα cosδ and δδα, the absolute deviations reach 30-40 mas for both MIS. For total systematic differences, local deformations of the FK5 system in the equatorial zone in both right ascension and declination has been found exceeding expected ones from the formal errors of the FK5 system by a factor about 1.5 for the MIS 60-70, and by a factor about 2 for the MIS 80. Consistency in area distribution between both MIS for the total systematic differences δαcosδ has been detected. Quick degradation of the FK5 system with time due to optimistic estimation of the errors of its proper motion system is supposed to be one of the main causes of its discrepancies with observations. The results in declination are recognized to be less reliable due to larger inconsistency of the individual instrumental systems.Before the next space astrometric mission will be realized, ground-based observations will continue to be the only available check of an external systematic accuracy of the HIPPARCOS catalogue. Evidently, random and, possibly, systematic accuracy of each individual catalogue observed from the Earth surface would be inferior to that of the HIPPARCOS catalogue. Taken as an ensemble, however, a certain selection of catalogues might give a rather definite idea about the actual distortions of the HIPPARCOS system. This study shows to which level of accuracy such ensembles of different selections of catalogues might check the HIPPARCOS system in the equatorial zone. The analysis of the FK5 gives also an idea about levels of random and systematic discrepancies which may be expected in the equatorial zone when the HIPPARCOS catalogue will be compared with the FK5 at different epochs.

Professor Jon Elster advances the proposal that Marx – and Marxists–really stand for ‘methodological individualism,’ as opposed to ‘methodological collectivism.’ He defines ‘methodological individualism’ in the following terms: Social science explanations are seen as three-tiered. First, there is a causal explanation of mental states, such as desires and beliefs … Next, there is intentional explanation of individual action in terms of the underlying beliefs and desires … Finally, there is causal explanation of aggregated phenomena in terms of the individual actions that go into them. The last form is the specifically Marxist contribution to the methodology of the social sciences.1

We conducted a dynamic common pool resource experiment and found large differences among groups in the total benefits (surplus) obtained from the resource. To shed light on the factors underlying the differences, we characterized individual appropriation decisions as irresponsible, sustainable, or constructive, and defined a measure of the intensity of such actions. We then examined the relationships between group-level success and the frequency and intensity of the individual actions, finding that the average intensity of irresponsible actions was the best predictor of group success. We interpreted this as suggestive evidence that policies aimed at preserving and maximizing the benefits of renewable resources should above all else aim to reduce the intensity of irresponsible actions.

Fichte’s ethics changed in many ways between 1794 and 1812: in the first place spiritual life replaced the transformation of nature; individual supersession was radicalized; and ethics was linked with first philosophy. In 1812 it was no longer a matter of inflecting natural necessity by means of the model image of an ideal world (Vorbild). The theme of image reappears as an externalizing of absolute life. Ethical action becomes a moment of this manifestation: a return to unity, following the process of fragmentation of the originary phenomenon (the I or the I-one), into an infinity of individual I’s. This fragmentation is fondamental: life is self-consciousness only in this individual form. The ethical act manifests the concept or image of God with the self-annihilation of individuality. Fichte had already written, in part XI of the Second Introduction, that the I, “only reasonnable”, “is no longer an individual”, and in the first Sittenlehre, § 18 : “We are all supposed to act identically”. Fichte’s final Ethics thus does not radicalize the supersession of the individual. It defines the rational individual by this supersession of himself [or herself], making ethics into a moment [stage] of the absolute life. The matter is not to merge the individual into the whole, but to partake in a living order, in the activity of the whole, which reaches out to each of its members, only to return to the first unity, by forming the whole as such.De 1794 à 1812, l’éthique de Fichte connaît plusieurs évolutions : abandon de la transformation de la nature au profit de la vie spirituelle, radicalisation du dépassement de l’individu, et rapprochement entre éthique et philosophie première. En 1812 il n’est plus question d’infléchir la nécessité naturelle par l’image modeèe (Vorbild) d’un monde idéal. La thématique de l’image apparaît comme extériorisation de la vie absolue. L’action éthique devient un moment de cette manifestation : le retour vers l’un, au terme d’un morcellement du phénomène originaire (le »Moi« ou »Moi un«) en une infinité de Moi(s) individuels. Cette diffraction est essentielle : la vie ne peut être consciente d’elle-même que dans cette forme individuelle. L’agir éthique manifeste le concept ou l’image de Dieu en anéantissant l’individualité. Mais la XIe section de la Seconde Introduction précisait déjà, que dans le monde moral, le Moi »uniquement raisonnable«, »a cessé d’être un individu« et dans la première Sittenlehre, § 18, Fichte écrivait : »Nous devons tous agir de la même manière«. L’éthique tardive ne radicalise donc pas le dépassement de l’individu. Elle définit l’individu rationnel par le dépassement de soi, en faisant de l’éthique un moment de la vie absolue. La question est donc moins de fondre l’individu dans un tout que de participer à un ordre vivant, à l’activité du tout qui va jusqu’à chacun des membres pour revenir vers l’unité première en constituant la totalité comme telle.

Abstract:If group members aim to fulfil a collective obligation, they must act in such a way that the composition of their individual actions amounts to a group action that fulfils the collective obligation. We study a strong sense of joint action in which the members of a group design and then publicly adopt a group plan that coordinates the individual actions of the group members. We characterize the conditions under which a group plan successfully coordinates the group members’ individual actions, and study how the public adoption of a plan changes the context in which individual agents make a decision about what to do.

In this paper, we investigate the absolute nodal coordinate finite element (FE) formulations for modeling multi-flexible-body systems in a divide-and-conquer framework. Large elastic deformations in the individual components (beams and plates) are modeled using the absolute nodal coordinate formulation (ANCF). The divide-and-conquer algorithm (DCA) is utilized to model the constraints arising due to kinematic joints between the flexible components. We develop necessary equations of the new algorithm and present numerical examples to test and validate the method.
