Phenomenological model of variant change during magnetization of martensite

The present study deals with the straining of ferromagnetic martensite in a magnetizing field. A phenomenological model of the movement of the interface between martensitic variants is developed for calculation of the strength of the magnetic field required for a variant change. The effect of uniaxial stress on interface movement is also examined. The results are applied to the martensite phases of NiMnGa and FePd ferromagnetic shape-memory alloys.     

Entropy,information and predictability of evolutionary systems

We investigate first several entropy concepts, from static to dynamic entropy. Dynamic entropy is introduced as a measure of predictability. Then the relation between entropy and information is studied. Following Wiener information is considered as a non‐physical quantity, not matter or energy. Information is understood as a binary relation between a sender and a receiver. We differentiate between bound and free information. Information can be created by selforganization, historically it is connected with the origin of life. The structure and predictability of informational strings is investigated. For example we study symbolic sequences generated by evolution, as e.g. texts. It is shown that several information carriers show criticality connected with the existence of long‐range correlations, long memory in time and historical behaviour (self‐tuned criticality). The higher order Shannon entropies and the conditional entropies (dynamical entropies and there limit) are calculated, characteristic scaling laws are found.     

Mapping the Structure of Semantic Memory

Aggregating snippets from the semantic memories of many individuals may not yield a good map of an individual’s semantic memory. The authors analyze the structure of semantic networks that they sampled from individuals through a new snowball sampling paradigm during approximately 6 weeks of 1‐hr daily sessions. The semantic networks of individuals have a small‐world structure with short distances between words and high clustering. The distribution of links follows a power law truncated by an exponential cutoff, meaning that most words are poorly connected and a minority of words has a high, although bounded, number of connections. Existing aggregate networks mirror the individual link distributions, and so they are not scale‐free, as has been previously assumed; still, there are properties of individual structure that the aggregate networks do not reflect. A simulation of the new sampling process suggests that it can uncover the true structure of an individual’s semantic memory.     

How the Free Spirit Became Free: Sickness and Romanticism in Nietzsche's 1886 Prefaces

This paper explores Nietzsche's account of the free spirit's genesis, as primarily given in the 1886 prefaces written for the works of his ‘free spirit trilogy’. In particular, it will focus on how what will be argued is the free spirit's distinguishing capacity for radical questioning is created out of the process described there. That is, it will examine how what Nietzsche calls, ‘the experience of sickness’, in enabling the free spirit's liberation, helps forge a mode of philosophical awareness which is not otherwise attainable. However, the second half of this paper goes on to explore how the success of this process is endangered by a certain psychological tendency to which free spirits are susceptible. In other words, the free spirit's chance of enduring those painful depths of sickness necessary for liberation is threatened by the appeal of ‘romantic pessimism’; a perspective which offers consolation by idealizing the sufferer's state. As such, then, in our final section, we will examine Nietzsche's efforts to combat this phenomenon. In particular, we will look at his advocacy of a specific kind of asceticism for this purpose, and with it his attempt to show how a true liberation of the spirit can be achieved.     

Four models of the functional contribution of mirror systems

In this paper we raise three questions of clarification about Alfred Mele's fine recent book, Free Will and Luck. Our questions concern the following topics: (i) Mele's combination of ‘luck’ and ‘Frankfurt-style’ objections to libertarianism, (ii) Mele's stipulations about ‘compatibilism’ and the relation between questions about free action and questions about moral responsibility, and (iii) Mele's treatment of the Consequence Argument.     

Objective Evaluation of Performance Stress in Musicians With Focal Hand Dystonia: A Case Series

Five musicians suffering from focal dystonia participated in a pilot study that examined the feasibility of an experimental protocol designed to assess musicians' motor performance under stress. Electrocardiography, free cortisol levels, and subjective assessments were used to monitor alterations of the hypothalamic-pituitary-adrenal axis. As measures of motor outcome, temporal variability of finger movements and muscular cocontraction of the wrist flexor and extensor were assessed. Findings suggest that the specific experimental design could be successfully applied. Several methodological issues such as carryover effects, the use of free cortisol, the inclusion of a double baseline, and the classification of dystonic patients into stress responders and nonresponders are analyzed and discussed.     

Linking mind,body and language: free association revisited

Psychoanalysis differs from other theories because of the great significance it attributes to a man's unconscious. Psychoanalysis differs fundamentally from other therapeutic methods in its use of free association and the significance and power it gives to this method when investigating unconscious phenomena. The present article begins with a brief review of the history of free association and its use as a method. After that, I discuss the relationship between free association and memory, neuropsychoanalysis and semiotics. Free association is linked with implicit memory and seen as a way of remembering; unconscious experiences are given a verbal form with the help of free association. The psychoanalytical setting and transference together constitute a psychic space, in which it becomes possible for the patient to get into touch with his or her bodily, psychic and verbal experiences and material simultaneously. The author sees free association specifically as a form of mental processing which is typical to psychoanalysis; it is a core process where the experiences of mind, body and language and their expressions link together. Free association is simultaneously the result of a memory activity and creative activity and, above all, a combination or synthesis of these two processes.     

Reply to Nadler: Spinoza and the metaphysics of suicide

Steven Nadler has argued that Spinoza can, should, and does allow for the possibility of suicide committed as a free and rational action. Given that the conatus is a striving for perfection, Nadler argues, there are cases in which reason guides a person to end her life based on the principle of preferring the lesser evil. If so, Spinoza’s disparaging statements about suicide are intended to apply only to some cases, whereas in others (such as the case of Seneca) he would grant that suicide is dictated by reason. Here, I object to Nadler’s interpretation by showing that it conflicts with Spinoza’s metaphysical psychology. Even given Nadler’s interpretation of the conatus doctrine, the possibility that reason could guide a person to commit suicide is incompatible with the conatus of the mind. Spinoza holds that the mind cannot contain an adequate idea ‘that excludes the existence of our body’ (E3p10). Yet, as I argue, in order for reason to guide a person voluntarily to end her life, she would need to have an adequate idea representing her death – an idea that excludes the existence of her body. For this reason, Spinoza's system rules out the possibility of rational suicide.     

PASTORAL COUNSEL FOR THE ANXIOUS NATURALIST: DANIEL DENNETT'S FREEDOM EVOLVES

Abstract: Daniel Dennett's Freedom Evolves is a rhetorically powerful but philosophically unconvincing attempt to show that a deterministic and ontologically reductionist, but epistemologically pluralist, outlook may peacefully coexist with a robust acceptance of human freedom and moral responsibility. The key to understanding the harmony rests in recognizing that freedom is not a metaphysical or physical condition but is instead a product of deeply embedded social practices. I argue that Dennett's project rests on an unargued and implausible deflationary stance toward basic metaphysics.     

COMPATIBILISM EVOLVES?: ON SOME VARIETIES OF DENNETT WORTH WANTING

Abstract: I examine the extent to which Dennett's account in Freedom Evolves might be construed as revisionist about free will or should instead be understood as a more traditional kind of compatibilism. I also consider Dennett's views about philosophical work on free agency and its relationship to scientific inquiry, and I argue that extant philosophical work is more relevant to scientific inquiry than Dennett's remarks may suggest.
