We establish that for every computably enumerable (c.e.) Turing degree b the upper cone of c.e. Turing degrees determined by b is the degree spectrum of the successor relation of some computable linear ordering. This follows from our main result, that for a large class of linear orderings the degree spectrum of the successor relation is closed upward in the c.e. Turing degrees.

We study the implications of model completeness of a theory for the effectiveness of presentations of models of that theory.

We study the weak truth-table and truth-table degrees of the images of subsets of computable structures under isomorphisms between computable structures. In particular, we show that there is a low c.e. set that is not weak truth-table reducible to any initial segment of any scattered computable linear ordering. Countable $\Pi _{1}^{0}$ subsets of 2ω and Kolmogorov complexity play a major role in the proof.

After a discussion of the possible connections between quantum mechanics and consciousness, and an examination of the circumstances under which some properties of a macroscopic system may be described by a quantum mechanical wave function, we propose three types of experiments in which one may search for the possible existence of quantal interference in mental events.

A defining characteristic of Alzheimer’s disease is difficulty in retrieving semantic memories, or memories encoding facts and knowledge. While it has been suggested that this impairment is caused by a degradation of the semantic store, the precise ways in which the semantic store is degraded are not well understood. Using a longitudinal corpus of semantic fluency data, we derive semantic network representations of patients with Alzheimer’s disease and of healthy controls. We contrast our network-based approach with analyzing fluency data with (...) the standard method of counting the total number of items and perseverations in fluency data. We find that the networks of Alzheimer’s patients are more connected and that those connections are more randomly distributed than the connections in networks of healthy individuals. These results suggest that the semantic memory impairment of Alzheimer’s patients can be modeled through the inclusion of spurious associations between unrelated concepts in the semantic store. We also find that information from our network analysis of fluency data improves prediction of patient diagnosis compared to traditional measures of the semantic fluency task. (shrink)

We re-express a previous general result in a way which seems easier to remember, using the terminology of infinite games. We show how this can be applied to construct recursive linear orderings, showing, for example, that if there is a ▵ 0 2β + 1 linear ordering of type τ, then there is a recursive ordering of type ω β · τ.

The texts before us are relatively early works. They predate the famous Manifesto of the Communist Party of 1848. Their importance lies in this: that here historical materialism is outlined and defended for the first time. This new philosophy is elaborated in the course of Marx and Engels' effort to settle accounts with previous German philosophy—and, perhaps, with philosophy as such. The new outlook is developed, therefore, in the context of polemic against Hegel and Feuerbach, precisely the thinkers that they (...) most admired earlier in fact. (shrink)

Those rights are human rights which, in Professor Gewirth's phrase, “all persons equally have simply insofar as they are human.” His task is to demonstrate that there are human rights, and to demonstrate that such demonstration is necessary to the very existence of these rights. “That human rights exist…is a proposition whose truth depends upon the possibility, in principle, of constructing a body of moral justificatory argument from which that proposition follows as a logical consequence.” As philosophers we should no (...) doubt like to be able to prove the existence of human rights – prove that there are such rights in the event that the fool shall have said in his heart that there are none, even using his folly against him by showing his denial to entail its denial – but it is a bold claim that rights are things whose esse est demonstrari.

Yvonne C. Zimmerman offers a groundbreaking exploration of the relationship between freedom and sexual regulation in American approaches to human trafficking.

In the majority of academic institutions nursing and medical students receive a traditional education, the content of which tends to be specific to their future roles as health care professionals. In essence, each curriculum design is independent of each course. Over the last decade, however, interest has been accumulating in relation to interprofessional and multiprofessional learning at student level. With the view that learning together during their student training would not only encourage and strengthen future collaboration in practice settings but (...) also enhance patient care, the University of Dundee decided to run a pilot study to explore shared teaching in ethics between medical and nursing students. This article presents a report on the reasons for selecting health care ethics as a precursor for shared teaching, the educational tool used for the sessions, and the results of student and facilitator evaluation of the short course. Overall, despite problems such as poor attendance by some students, and facilitation and timetable difficulties, most of the feedback from students and facilitators has been positive. In essence the ‘idea’ has gone from strength to strength and there are now three levels of shared teaching in ethics between nursing and medical students, with plans to include further sessions with students from other disciplines. Within the text, ‘health care ethics’ will be referred to as ‘ethics’; nursing students/nurses encompasses midwifery students/midwives. (shrink)

Professor Austin explores four main areas in this paper. First of all he outlines the physical development of sex differentiation in the embryo. He develops this by describing the clinical manifestations of abnormality which can appear at that stage. Professor Austin points out that there are relatively few people with abnormalities and that those who do show homosexual tendencies are not noticeably different from the norm in terms of their sexual equipment and hormone levels. It is much more likely that (...) their psychological and social development has a greater influence in differentiating them sexually. The last section of the paper is a synopsis of society's reactions to homosexuality or bisexuality which term in Professor Austin's opinion is more accurate and descriptive of the condition.

In lieu of an abstract, here is a brief excerpt of the content:Response to Eva Alerby and Cecilia Ferm, “Learning Music: Embodied Experience in the Life-World”C. Victor FungThe authors' choice of using phenomenology as a foundation of their inquiry is appropriate and appealing. They have, to a great extent, achieved their goal to explain music learning from a life-world approach. Descriptions of absolute musicality and relativistic musicality in the opening paragraphs remind me of the good old "nature versus nurture" argument. (...) Do the authors intend to relate musicality to musical ability or aptitude as defined by psychologists? If musicality is "the ability to make something of one's own," does it mean that the authors have taken on a relativistic view and believe that musicality can be acquired?At the onset of the essay, musicality is described as emotional or cognitive phenomena. I would be interested to know what role a psychomotor phenomenon plays in musicality. The authors later describe "motor knowledge" in the context of Merleau-Ponty's "maximum grip." Does it mean that "motor knowledge" or "maximum grip" in music is outside the realm of musicality?I have attempted to follow the authors' logic in answering the question: What is learning of music? The authors postulate that "knowledge does not always, and not in any way automatically, become exactly the same as the learning situation aimed for" and that "the aim of music education is to produce music knowledge." These propositions lead me to believe that the learning of music occurs in experiencing all types of musical activities, regardless of the musician's level of proficiency. In all types of musical activities, including different performances of the same repertoire by the same performer, the musician would find new knowledge that is being produced in his/her body. Therefore, I agree with the authors in that "bodily experience is the foundation for learning."I would like to respond to the issue of whether music learning occurs within [End Page 206] or outside of the human being. I enjoy reading how the authors borrow Merleau-Ponty's analogy of the blind man and his stick. They put it so beautifully that "the piano becomes an extension of the pianist's body, and the pianist can 'feel' its limitation." This leads me to ponder if there could be further extensions beyond the physical piano. We know that pianists make the strings in the piano vibrate through a lever mechanism. These vibrations travel through the air and arrive at the audience's ears. Then the vibrating energies are transmitted as electrical energies in the audience's nerve cells. The audience in turn may behave differently after such a complex transmission of energies at a performance. My question is: Is there an end to the "extension" of a musician's body? If so, where should it end? There is no doubt that the pianist relates to the world and learns about the world through the piano. Could the pianist learn about the world through the vibrations that the piano strings generate, through the air, and through the audience's hearing mechanism, brain cells, and behaviors? Is this what the authors meant by "the human ego is boundaryless and cannot be localized, and the ego is immanent in the whole system"? Regardless of how far the "extension" goes, how do we know if an "extension" has occurred? How can we validate an "extension" of a musician's ego"?It seems to me that the authors' discussions have focused on the tactile extension of the body. If the body can be extended like the stick for the blind man, would the air surrounding the blind man, including its smell, temperature, humidity, wind, and sound, be his extension too? When this question is transferred to a musician, would the total context of the musical event be the musician's extension of the body too? By "total context," I mean the cultural context, the environment (smell, temperature,...), and the people in the musical event.We are certain that music learning takes place when experiences and knowledge are incorporated in the body. We still have not solved the problem of whether music learning occurs within or outside of the human being, because the boundary of the... (shrink)

We extend the work of Ivancovsky et al. by proposing that in addition to novelty seeking, mood regulation goals – including enhancing positive mood and repairing negative mood – motivate both creativity and curiosity. Additionally, we discuss how the effects of mood on state of mind are context-dependent (not fixed), and how such flexibility may impact creativity and curiosity.
