The complex chaotic dynamics and multistability of financial system are some important problems in micro- and macroeconomic fields. In this paper, we study the influence of two-delay feedback on the nonlinear dynamics behavior of financial system, considering the linear stability of equilibrium point under the condition of single delay and two delays. The system undergoes Hopf bifurcation near the equilibrium point. The stability and bifurcation directions of Hopf bifurcation are studied by using the normal form method and central manifold theory. (...) The theoretical results are verified by numerical simulation. Furthermore, one feature of the proposed financial chaotic system is that its multistability depends extremely on the memristor initial condition and the system parameters. It is shown that the nonlinear dynamics of financial chaotic system can be significantly changed by changing the values of time delays. (shrink)

Die sekundäre Forschungsnutzung von Behandlungsdaten hat großes Potenzial, biomedizinisches Wissen zu erweitern und die Patientenversorgung zu verbessern. Gleichzeitig sind für eine bessere Ausschöpfung dieses Potenzials diverse Herausforderungen zu bewältigen. Dies gilt insbesondere in Deutschland, wo im Vergleich zu anderen Ländern, wie z.B. Dänemark oder Finnland, die sekundäre Forschungsnutzung von Behandlungsdaten unterentwickelt ist. Die Intensivierung der Nutzung der Daten aus Diagnose und Therapie von Patienten und die Entwicklung der dafür notwendigen Strukturen in Deutschland ist ethisch und politisch geboten: für die Verbesserung (...) der Gesundheitsversorgung durch neue Erkenntnisse, Therapien und Qualitätssicherung. Aus diesem Grund fordern die Autor:innen alle Akteure des Gesundheitssystems, von der Bundes- und den Landesregierungen über die Krankenkassen, Kliniken, Ärzt:innen und Patient:innen dazu auf, einen Beitrag dazu leisten, eine Kultur der sekundären Forschungsnutzung von Behandlungsdaten zu etablieren. Basierend auf den Ergebnissen eines dreijährigen Verbundprojekts beantworten die Autor:innen aus den Bereichen Medizin, Rechtswissenschaften, Ethik und Sozialwissenschaften die Frage was notwendig ist, damit in Deutschland die Daten von Patient:innen systematisch für medizinische Forschung und die Analyse der klinischen Versorgungsqualität verwendet werden können und wirklich auch verwendet werden. Sie nennen zehn zentrale Forderungen und legen eine Liste von 23 Empfehlungen mit konkreten Maßnahmen vor, welche von den genannten Akteuren umgesetzt werden sollten. (shrink)

La philosophie de la religion de Wittgenstein et des philosophes analytiques qui l’ont suivi est-elle ou non un fidéisme ? Le livre est né d’une rencontre tardive entre deux penseurs qui ont engagé le débat, indépendamment l’un de l’autre, au milieu des années soixante. Au terme d’une douzaine de chapitres composés en alternance, à l’écriture toujours serrée et au ton parfois vif, les auteurs n’abandonnent pas leurs positions initiales, même si elles se sont nuancées avec les années.

I thought the paper by Kai-yee Wong and Chris Fraser was fascinating and insightful. Two things I especially appreciated are the clarity with which they summarize my views. I think they are quite fair and accurate. Second, I appreciate their suggestion that the way to deal with the practical problem of weakness of will has much to do with the role of the Background in shaping our actions. I think they are especially on the right track when they say that (...) the improvement of Background skills may actually narrow the range of real options for action, (p. 21) nonetheless, they do not decrease freedom. As they say, “It is a process of strengthening the self, and the agent is likely to experience the concomitant restriction of ‘live’ options not as a limitation but as strength of character.” (p. 21). That seems to me very much on the right track. What they are suggesting, and it is a powerful addition to my own writings, is that we should not just think of the Background as facilitating languages, games and social practices generally, but for morality as well (p. 23).

We investigate whether ordinary quantification over objects is an extensional phenomenon, or rather creates non-extensional contexts; each claim having been propounded by prominent philosophers. It turns out that the question only makes sense relative to a background theory of syntax and semantics (here called a grammar) that goes well beyond the inductive definition of formulas and the recursive definition of satisfaction. Two schemas for building quantificational grammars are developed, one that invariably constructs extensional grammars (in which quantification, in particular, thus (...) behaves extensionally) and another that only generates non-extensional grammars (and in which quantification is responsible for the failure of extensionality). We then ask whether there are reasons to favor one of these grammar schemas over the other, and examine an argument according to which the proper formalization of deictic utterances requires adoption of non-extensional grammars.

It is not quite as easy to see that there is in fact no formula of this modal language having the same truth conditions (in terms of S5 Kripke semantics) as (1). This was rst conjectured by Allen Hazen2 and later proved by Harold Hodes3. We present a simple direct proof of this result and discuss some consequences for the logical analysis of ordinary modal discourse.

African ethics is primarily concerned with community and harmonious communal relationships. The claim is frequently made on behalf of African moral beliefs and customs that, in stark contrast with Western moral attitudes and practices, there is no comparable objectification and exploitation of other-than-human animals and nature. This article investigates whether this claim is correct by examining the status of animals in religious and philosophical thought, as well as traditional cultural practices, in Africa. I argue that moral perceptions and attitudes on (...) the African continent remain resolutely anthropocentric. Although values like ubuntu or ukama have been expanded to include nonhuman nature, animals are characteristically not seen to have any rights, and human duties to them are almost exclusively “indirect.” I conclude by asking whether those who, following their own liberation, continue to exploit and oppress other creatures—simply because they can—are not thereby contributing to their own dehumanization.

On the dominant contemporary accounts of how practical considerations affect what we ought to believe, practical considerations either encroach on epistemic rationality by affecting whether a belief is epistemically justified, or constitute distinctively practical reasons for belief which can only affect what we ought to believe by conflicting with epistemic rationality. This paper argues that Søren Kierkegaard offers a promising alternative view on which practical considerations can affect what we ought to believe without either encroaching on or (necessarily) conflicting with (...) epistemic rationality by determining which among the epistemically permitted outright doxastic attitudes one should all‐things‐considered adopt.

The sense of agency is a basic feature of our subjective experience. Experimental studies usually focus on either its attributional aspects or on its motoric aspects. Here, we combine both aspects and focus on the subjective experience of the time between action and effect. Previous studies [Haggard, P., Aschersleben, G., Gehrke, J., & Prinz, W.. Action, binding and awareness. In W. Prinz, & B. Hommel, Common mechanisms in perception and action: Attention and performance. Oxford: Oxford University Press] have shown a (...) temporal attraction in the perceived times of actions and effects, but did directly not study the relation between them. In three experiments, time estimates of an interval between an action and its subsequent sensory effect were obtained. The actions were either voluntary key press actions performed by the participant or kinematically identical movements applied passively to the finger. The effects were either auditory or visual events or a passive movement induced to another finger. The results first indicated a shortening of the interval between one’s own voluntary action and a subsequent effect, relative to passive movement conditions. Second, intervals initiated by observed movements, either of another person or of an inanimate object, were always perceived like those involving passive movements of one’s own body, and never like those involving active movements. Third, this binding effect was comparable for auditory, somatic and visual effects of action. Our results provide the first direct evidence that agency involves a generalisable relation between actions and their consequences, and is triggered by efferent motor commands. (shrink)

Drawing on insights of thinkers in the natural rights tradition, Draper analyzes numerous hypothetical cases including those involving a runaway trolley, then seeks to determine if killing civilians in war is ever justified. In his consideration of this issue he avoids appealing to the principle of double effect. Having considered hypothetical cases at length, he leaves it to others to decide if any option to go to war is justifiable. In this regard he himself is sceptical.

The aim of this Web-based survey of 15 German companies with an international profile was to identify which higher-level values serve as a basis for a company culture that promotes integrity and can thereby also be used to promote crime prevention. Results on about 2000 managers in German parent companies and almost 600 managers in Central and North European branch offices show that a major preventive role can be assigned to a company culture that promotes integrity. This requires a ‘tone (...) from the top’, ‘ethical leadership’ from the direct superior, and a general set of values that can be encouraged through training courses. Moreover, employees have to perceive these values as promoting their careers. The survey reveals that the companies in this study have basically succeeded in establishing their system of values in their Central and North European as well as their Asian branch offices. Moreover, it shows that the main values preventing crime on the management level are trustworthiness and consistency. Open communication is an important value on all levels of a company, and this is supplemented by transparency, compliance with the rules, and a rejection of behaving in one’s own interest. It is concluded that in spite of regional differences, major international companies can possibly make an important contribution to bringing about cultural change in regions with an affinity for corruption by implementing a culture that promotes integrity in both their company and their daily business.

Many find the prospect of death distressing at least partly because they believe that death deprives its subject of life’s benefits. Properly qualified, the belief is surely true. But should its truth lead us to conclude that there is something dreadful or awful about death, something that merits distress?

The human self model comprises essential features such as the experiences of ownership, of body-centered spatial perspectivity, and of a long-term unity of beliefs and attitudes. In the pathophysiology of schizophrenia, it is suggested that clinical subsyndromes like cognitive disorganization and derealization syndromes reflect disorders of this self model. These features are neurobiologically instantiated as an episodically active complex neural activation pattern and can be mapped to the brain, given adequate operationalizations of self model features. In its unique capability of (...) integrating external and internal data, the prefrontal cortex (PFC) appears to be an essential component of the neuronal implementation of the self model. With close connections to other unimodal association cortices and to the limbic system, the PFC provides an internally represented world model and internal milieu data of the organism, both serving world orientation. In the pathophysiology of schizophrenia, it is the dysfunction of the PFC that is suggested to be the neural correlate for the different clinical schizophrenic subsyndromes. The pathophysiological study of psychiatric disorders may contribute to the theoretical debate on the neuronal basis of the self model. (shrink)

In this paper, we discuss three probabilistic arguments for the existence of multiple universes. First, we provide an analysis of total evidence and use that analysis to defend Roger White's "this universe" objection to a standard fine-tuning argument for multiple universes. Second, we explain why Rodney Holder's recent cosmological argument for multiple universes is unconvincing. Third, we develop a "Cartesian argument" for multiple universes. While this argument is not open to the objections previously noted, we show that, given certain highly (...) plausible assumptions about evidence and epistemic probability, the proposition which it treats as evidence cannot coherently be regarded as evidence for anything. This raises the question of whether to reject the assumptions or accept that such a proposition cannot be evidence. (shrink)

Hitchcock advances a diachronic Dutch Book argument (DDB) for a 1/3 answer to the Sleeping Beauty problem. Bradley and Leitgeb argue that Hitchcock’s DDB argument fails. We demonstrate the following: (a) Bradley and Leitgeb’s criticism of Hitchcock is unconvincing; (b) nonetheless, there are serious reasons to worry about the success of Hitchcock’s argument; (c) however, it is possible to construct a new DDB for 1/3 about which such worries cannot be raised.

The claim is frequently made on behalf of African moral beliefs and customs that African society does not objectify and exploit nature and natural existents, unlike Western moral attitudes and practices. This book investigates whether this claim is correct by examining religious and philosophical thought, as well as traditional cultural practices in Africa.

Animals and African Ethics concludes by asking whether those who, following their own liberation, continue to exploit and oppress other creatures, are not thereby contributing to their own dehumanization.

The subjective experience of time is a fundamental constituent of human consciousness and can be disturbed under conditions of mental disorders such as schizophrenia or affective disorders. Besides the scientific domain of psychiatry, time consciousness is a topic that has been extensively studied both by theoretical philosophy and cognitive neuroscience. It can be shown that both approaches exemplified by the philosophical analysis of time consciousness and the neuroscientific theory of cross-temporal contingencies as the neurophysiological basis of human consciousness implemented in (...) the prefrontal cortex converge in 2 respects. Firstly, a tripartite conception of consciousness divides human cognition in 3 different temporal domains comprising retention, presentation, and protention and the past, the present, and the future corresponding to working memory, interference control, and preparatory set. Secondly, both concepts refer to the present as an extended duration that integrates information from the recent past and the future. We propose that the integration of phenomenological and neuroscientific approaches can stimulate the development of enriched pathophysiological concepts of mental disorders. This approach appears to be particularly fruitful with respect to schizophrenia that is interpreted as a structural disturbance of time consciousness. (shrink)

This paper studies the state of charge estimation of supercapacitors and lithium batteries in the hybrid energy storage system of electric vehicles. According to the energy storage principle of the electric vehicle composite energy storage system, the circuit models of supercapacitors and lithium batteries were established, respectively, and the model parameters were identified online using the recursive least square method and Kalman filtering algorithm. Then, the online estimation of SOC was completed based on the Kalman filtering algorithm and unscented Kalman (...) filtering algorithm. Finally, the experimental platform for SOC estimation was built and Matlab was used for calculation and analysis. The experimental results showed that the SOC estimation results reached a high accuracy, and the variation range of estimation error was [−0.94%, 0.34%]. For lithium batteries, the recursive least square method is combined with the 2RC model to obtain the optimal result, and the estimation error is within the range of [−1.16%, 0.85%] in the case of comprehensive weighing accuracy and calculation amount. Moreover, the system has excellent robustness and high reliability. (shrink)

This article re-examines the role of the brain in self-recognition. It reconsiders the idea that the frontal and cortical midline structures are important for self-specific experience in light of several recent reviews of neuroscience literature. The findings suggests that the frontal cortex and the cortical midline structure are not the only areas involved in self-related tasks and that these areas may be involved not because the tasks are self-specific, but because they are tasks that involve a specific kind of cognitive (...) operation, specifically reflective evaluation.

We see a systematic set of cut-free axiomatisations for all the basic normal modal logics formed by some combination the axioms d, t, b, 4, 5. They employ a form of deep inference but otherwise stay very close to Gentzen’s sequent calculus, in particular they enjoy a subformula property in the literal sense. No semantic notions are used inside the proof systems, in particular there is no use of labels. All their rules are invertible and the rules cut, weakening and (...) contraction are admissible. All systems admit a straightforward terminating proof search procedure as well as a syntactic cut elimination procedure. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:On Substance Being the Same As Its Essence in Metaphysics Z 6: The Pale Man ArgumentNorman O. Dahlin general Aristotle’s account of substance in the Categories is clear. Primary substances, the basic constitutents of the world, are independently existing individuals, paradigm examples of which are particular living organisms. However, the later use to which Aristotle puts matter and form provides him with two new candidates for primary substance.1 A (...) reconsideration of substance is in order, and Aristotle begins it in Metaphysics Z. The status of matter soon becomes clear. It can’t be substance because it isn’t a “this” and separate (Z 3, 1029a26–28). The status of form, however, is another story. Aristotle argues in Z 6 that substances are the same as their essences. While the evidence isn’t unequivocal, Z 4, 10, 11, and 15 take essence to be form, where form is universal. Z 13, however, argues that no universal is substance. Aristotle thus appears caught in an inconsistency. Substance is universal form because it is the same as universal form; however, no universal is substance. This and other problems have led to as wide a variety of interpretations of Metaphysics Z as one will find of any philosophical text. Virtually all of them end up attributing to Aristotle one of [End Page 1] three views about substance—substances are universal forms, particular forms, or composites of matter and form.2This paper takes a first step in a project that promises to remove the above inconsistency while allowing but not requiring Aristotle to take concrete particular substances (composite substances involving both matter and form) to be substances. The project looks at the first of the three claims that lead to the above apparent inconsistency and asks whether the sameness relation in it should be understood as identity or a weaker relation that could hold between concrete particular substances and their universal essences. It is the latter possibility that promises to avoid the above contradiction. If concrete particular substances can be the same as their universal essences, then the essences of substances can be universals without necessarily turning substances into universals. Nevertheless, granting this possibility wouldn’t require Aristotle to take concrete particular substances to be substances. Forms of concrete particular substances will also be the same as their essences in this weaker sameness relation, and considerations other than those at work in Z 6 could still lead Aristotle to rule out concrete individuals as substances.1Although Aristotle has standardly been interpreted as arguing in Z 6 that substances are identical with their essences,3 two considerations allow the question of this paper to be raised. [End Page 2]The first is the variety of uses to which Aristotle puts such notions as the same (tauto) or one (hen). Aristotle’s concern in Z 6 is with whether certain things are or are not the same (tauto), one (hen), or one and the same (hen kai auto and to auto kai hen) as their essences.4 He argues that kata sumbebēkos legomena (things said to be what they are with respect to an accident) are not the same as their essences, but that kath’ hauta legomena (things said to be what they are with respect to themselves), a class of things that includes substances,5 are the same as their essences. However, when Aristotle says that one thing and another are the same or one, there is more than one kind of claim he can be making. Some of them apply to things that are identical; others do not.For example, things can be the same in number, species, and genus. A doublet and a cloak are the same in number, a man and another man are the same in species, and a man and a horse are the same in genus.6 Although a doublet and a cloak are identical, a man and another man, and a man and a horse, are not.Things can also be accidentally the same, or the same in definition, substance, or essence,7 where these two ways of being the same cut across the previous ways of being the same. For example... (shrink)
