A repulsive core force is derived which, assuming π mesons are the field particles, gives binding energies in good agreement with binding energies per nucleon of heavy nuclei. The physical model consists of a field of relatively short range, in which emission of a π meson by a nucleon and subsequent absorption by a neighboring nucleon is equivalent to a potential well. The binding energy at the equilibrium spacing of the nucleons is the self-energy of the π mesons, which is (...) calculated by analogy with classical electric fields. (shrink)

A book which might well become a classic on Heidegger. Richardson discusses most of Heidegger's works in chronological order, offering a close analysis of each. Most chapters include a general exposition of the argument of the work discussed, a detailed analysis of the problems of Thought, Being and Dasein in the work, and a résumé. While maintaining very high standards of scholarly precision in the rendering of Heidegger's ideas and terminology, Richardson yet succeeds in making his book very readable and (...) lucid. Without "supplementing" Heidegger in any way, refraining from explanatory speculations and staying always very close to the text, he manages to clarify some of the most difficult passages of Heidegger's works. His frequent cross-references make the commentary of genuine value to the advanced student as well as to the novice. Heidegger, in his own preface to the book, criticizes Richardson for the sharp distinction between Heidegger I and Heidegger II, but gives a most important substantiation to two of the author's main theories, viz., the difference between Heidegger's Seinsdenken and Husserl's phenomenology, and the central status of the concept of Ereignis in Heidegger's philosophy. Richardson regrettably does not pursue the Heidegger III suggested by Vycinas, the Heidegger of the Geviert, the question of the nature of Being as such. In some chapters at least this omission makes the interpretation seem partial and sometimes inexact. One hopes for a sequel as good and illuminating.—E. M. Z. (shrink)

Unlike most anthologies in aesthetics and the philosophy of art, the present selection does not try to collect representative extracts from the writings of most, or even many, important aestheticians throughout the ages. It aims for depth rather than width and tries to do as much justice as possible to those aestheticians which it does include, without bothering much about those left out. The result is really impressive. No less than 138 pages are devoted to Plato and Aristotle alone, where (...) the reader may find not only the usual passages from the Poetics and the Rhetoric but also relevant material from De Partibus Animalium and Politica. Such an anthology, so it seems, must be an opinionated one. Thus, while it contains some 70 pages of Dewey's Art as Experience, there is not a single line of Santayana in it. Although I disagree with the choice made in this case, I cannot but admire the courage it took to make it. Another surprise is the inclusion of the relatively obscure mediaeval thinker, Marsilio Ficino, in an anthology which excludes Baumgarten, Lessing, Burke, Schiller, Coleridge, Bosanquet and Alexander, to mention but few, and whose sole contemporary representative is Heidegger. The extracts from Ficino's commentary on Plato prove, however, to be highly interesting and relatively original, too. Thus, even if Ficino is not as great as some of the aestheticians not included in this volume, I, for one, would not regret this mark of personal, off-beat, taste. The last selection, Heidegger's "The Origin of the Work of Art," appearing for the first time in English translation, comes as special bonus to the reader. The editors' introductions to each selection are generally concise, precise, and very helpful. Sometimes, however, one may find an exception: in their introduction to the Heidegger translation, the editors characterize the Kehre as a "reversal... from the stress on anxiety, nothingness... to a stress on more affirmative moods." This is, to say the least, a grossly misleading remark, which is likely to confuse the student of the later Heidegger rather than help him.—E. M. Z. (shrink)

A collection of commentaries on various theories in aesthetics, similar in method and aim to Kainz's Vorlesungen. Far from placing "the study of aesthetics on a new footing" or grasping "the scope of the subject as a whole," as the dust jacket declares, it is still a useful, well organized and often illuminating manual for the student of aesthetics. Sparshott treats some problems clearly and succinctly, but many other questions, such as the mode of being of the work of art (...) or the possibility of regarding art as a cognitive form, are not even mentioned. It also seems that some familiarity with at least the main currents in aesthetics on the continent and a more systematic conception of the field of aesthetics as a whole would have brought Sparshott closer to his stated aims.—E.

Parry’s volume is not an elementary book, but it is apparently intended as an introduction to Locke’s political thought for students. While he definitely has a point of view of his own, he attempts to draw together much of the recent critical thought on Locke. Parry’s volume differs from much of the recent work on Locke in being, one might say, "sweet-tempered." He is sweet-tempered in the first place toward Locke. Unlike so much of the recent scholarly-historical literature, he clearly (...) respects Locke. In a field marked by acrimony among scholars, Parry is also remarkably sweet tempered toward other Locke scholars; he builds on the work of others where possible, rather than emphasizing his own novelty and uniqueness. He thus produces a far more balanced treatment than most. For example, he accepts willingly the Laslett-sponsored arguments that the Second Treatise is aimed against Filmer as was the First, but he refuses to toss out entirely the older view that it is aimed in some measure against Hobbes. Although Parry is probably least tolerant towards the Strauss approach to Locke, he is even able to find large areas where he endorses moderate versions of that position, for example, on the important range of similarities between Hobbes and Locke. Parry’s "harmonizing approach" shows up also in the unusually wide range of Lockean sources from which he draws. He uses not only the standard fare of the Second Treatise and the Essays on the Law of Nature, but also the works on education, toleration, and economics to good effect. Disappointingly scanty, however, is the place of the First Treatise and even the Essay. His harmonizing approach shows up most importantly, however, in his attempt to combine the two chief sorts of attention Locke has received in recent years. On the one hand, there is the Locke scholarship properly so-called. While there are several varieties and orientations within this literature, no doubt the leading one has taken a very historical approach—attempting to understand Locke in his historical context and deploying religious or theological categories as the chief means for doing so. This approach shuns "present-mindedness" above all other intellectual vices. While Parry announces his general adherence to this approach he attempts to take account of the other main sort of interest in Locke today—as a source and inspiration for a very live contemporary tradition of political thinking, represented by Nozick and Rawls. Parry uses these contemporary "Lockeans" to help interpret the Second Treatise, leaning for example on Rawls’s formulation of the problem social contact theory attempts to answer, and Nozick’s doctrine of "entitlements." Parry’s refusal to be terrified by the strictures against "present-mindedness" produce some of the best and most valuable features of the book, as when he seriously asks what Locke means today, or how other contemporary political views differ from Locke’s. On the other hand, his reading of Locke on political economy suffers a bit perhaps from over-domination by Nozick’s restatement. Parry attempts to give both devils their due by agreeing with the historical school that Locke’s thought must be read historically, as Christian or theological, in a form that could hardly be acceptable to any contemporary political thinkers, and agreeing with the contemporary Lockean tradition that "to a very considerable extent" Locke’s position "can and must be…assessed and understood apart from its theological substructure." Those theological foundations are, Parry admits, very problematical. In fact, with a post-Humean eye, "it can become difficult to persuade oneself even that Locke could have found his position consistent." Yet Parry affirms "there is no doubt that Locke found the argument satisfying." But he supplies no reason—other than the fact that Locke deployed such arguments on more than one occasion—for this conclusion. Surely gross inconsistencies in argument are grounds for doubt. Parry should have at the least entertained Leo Strauss’s hypothesis about Locke’s manner of expression in light of his own views that Locke’s expressed theological underpinnings are unacceptable philosophically, and that Locke’s position can rest on altogether independent nontheological grounds. Moreover, Parry’s concession that Locke cannot move successfully from those religious underpinnings to the all-important content of the law of nature supplies further grounds for considering the same hypothesis. Parry’s treatment shares with most of the historical approaches to Locke the defect of "slackness"—when we come to something inconsistent or difficult to understand, we write it off as the product of Locke’s faith, internally meaningful, believable to him. Only in Parry’s case this is more problematical yet, for he rightly insists that we see Locke’s position as nonarchaic, and thus makes the reader eager for probing analysis and justification rather than loose appeals to Locke’s times. In order to connect the theological underpinnings to the political arguments, Parry is driven to some most un-Lockean notions such as the duty of "an individual to stretch himself to the full." For a similar reason, we suspect, freedom, which plays an extremely large part in Parry’s exposition, nowhere receives an adequate rooting in Locke’s discussion in the Essay, nor does Locke’s hedonism play a sufficient part in Parry’s interpretation.—M.Z.

This book contains twenty-two papers by K. Ajdukiewicz, an outline of his memoir and philosophical evolution by J. Giedymin, and a bibliography of Ajdukiewicz’s works compiled by T. Czezowski. In the colorful introductory paper, Giedymin characterizes the personality of the famous Polish philosopher-logician as a person open not only to philosophical investigations but also to contemplation of the beauty contained in music, literature, and nature. The sketch of Ajdukiewicz’s scientific activity presents him as an excellent teacher, open-minded in understanding different (...) viewpoints but simultaneously as an independent and uncompromising thinker.

The first six chapters of this book present and criticize six views of the nature of proper names, among which are theories that proper names have no meaning or connotation, that proper names have more meaning than other signs or that their meaning is infinite, that ordinary proper names should be analysed into "logically" proper names, etc. This part of the book is the best. One may find in these chapters several well-reasoned arguments which seem to totally demolish the theories (...) under investigation. Chapters seven to nine present the author's own solution to the problem. Sørensen holds that a proper name does have a meaning—otherwise it would not have been a part of language at all. The meaning of a linguistic sign, he argues, is a set of conditions to be satisfied by an extra-linguistic entity, such that this entity may be identified as denoted by the said sign. A proper name is an individual name, and its meaning is a series of necessary and sufficient conditions for the identification of the individual entity which this name is intended to denote. It is Sørensen's view that this series consists of a definite description of final length including space and time indicators. The definiens formula for proper names is thus 'P' = 'the x that... t... p....' The discussion of this proposal is, however, greatly impaired by Sørensen's utter disregard for the rich philosophical literature existing on the subject: no attempt is made to confront his view with the now standard arguments against theories of that type. Even many inner difficulties of the proposed solution are ignored. E.g., one may ask what values do 't' and 'p' take in the definition of 'Zeus'. Or take the following puzzle: are 'The x that taught Aristotle in p at t' and 'The x that studied with Socrates in p at t' both the meaning of 'Plato'? Sørensen's view that "A national register may be looked upon as a dictionary of proper names" suggests a positive answer, but surely R and S cannot be the same meaning. Many similar problems bother the reader of Sørensen's book, but, unfortunately, they are nowhere discussed.—E. M. Z. (shrink)

Rudolf Carnap, remembering in his Autobiography a visit to Warsaw in November 1930, and recalling animated discussions with Lesniewski, Kotarbinski, and Tarski, expressed deep regret that stimulating and fruitful works in the field of logic and theory of knowledge, published only in the Polish language, were inaccessible to the philosophical world. An analogous opinion is expressed by Karl R. Popper who has stated that his methodological solutions were influenced by Alfred Tarski more than by anybody else. Regarding similar appraisals and (...) trying to partially eliminate the mentioned barrier of the language, D. Reidel Publishing Company has edited an anthology of methodological papers published in Poland between 1947-72. The anthology consists of thirty-three articles by twenty Polish logicians investigating the issues of the general methodology of empirical sciences. (shrink)

Although some of Helmholtz’s scientific suggestions are dated with the progress of science, his ontological statements as well as his epistemological studies are still an object of philosophical controversy. The selection of Helmholtz’s epistemological writings, edited as volume 79 in the Synthese Library, contains four papers originally published in German between 1868 and 1887. In these papers are considered among others the epistemological aspects of measuring and numbering, the issues of perceptual cognition, the theory of geometrical knowledge, and the relationship (...) between science and metaphysics. The present collection of the Helmholtz’s articles was previously edited in German, on the centenary of his birth, under the title Schriften zur Erkenntnistheorie. The editors, M. Schlick and P. Hertz, sharing the opinion that Helmholtz’s name is a symbol of a union between epistemologically oriented philosophy and science, had selected from his many epistemological writings only four—the most representative and the most complete. In order to make the papers intelligible not only to philosophers but also to general readers, Schlick and Hertz supplemented the primary texts with explanatory remarks and comments. Some of them have a general introductory character, explaining, for instance, the difference between induction and deduction or elucidating Locke’s conception of two kinds of properties; the others present useful syntheses of methodological solutions, comparing, e.g., Carnap’s or Reichenbach’s ideas with Helmholtz’s.

To consider power as not only the direct physical oppression of others, but as a production of authority through discursive knowledge and a claimed ‘expertise’ of the world, has been one of Foucault’s great legacies to critical work on mental health and illness. As arbiters of the ‘truth’ on what is and what is not mental pathology, I agree with Swerdfager that the privileged knowledge of the mental health professions and the consequential marginalization of other forms of knowledge on distress (...) can be better theorized through an investigation of the power/knowledge nexus. Practically, scholars and researchers can begin to address these... (shrink)

In the rapidly evolving field of wireless power transfer (WPT), achieving systems that combine efficiency with reliability is crucial. This paper presents a simulation-based approach using CST Studio Suite to optimize WPT systems for wireless battery chargers in electric bikes. The study fixes the size of both the transmitter and receiver coils, the spacing between turns, and the number of coil turns, with a set distance of 20mm between the transmitter and receiver coils. CST Studio Suite is employed to determine (...) the parameters of resonance capacitors and the optimal switching frequency to enhance WPT efficiency. This powerful simulation tool allows researchers and engineers to design resonance compensation circuits more effectively, optimizing power transfer efficiency. The simulation conducted with CST Studio Suite confirms its effectiveness in designing a WPT system, achieving an impressive peak efficiency of 99.61% at the resonant frequency. The paper demonstrates CST Studio Suite's capability to accurately predict WPT system performance by developing detailed electromagnetic models and fine-tuning simulation parameters to reflect real operating conditions. Iterative simulations resulted in optimized practices, validated by select results that highlight the method's effectiveness and showcase an optimal balance between system complexity and efficiency. These findings provide a strategic framework for future WPT system development, offering practical guidance for researchers and industry professionals aiming to advance WPT technology. (shrink)

The complexity of biobank research raises concerns about individuals’ understanding of the information conveyed in the consent process for such research.. We report the results of a qualitative, cognitive interview study with an ethnically, linguistically, and educationally diverse sample of 43 respondents to assess the clarity and utility of a multimedia tool developed for a biobank. Using weighted randomization, respondents were assigned to either view the multimedia tool or read a written consent document . The study illustrates the utility of (...) cognitive interviews for gaining insights from prospective research participants about the clarity of informed consent tools. Findings suggest that a multimedia tool is useful for communicating key messages but should be combined with a written consent document and personal interaction with the study staff. We recommend that the potential value of multimedia tools should be more rigorously tested in a randomized controlled trial. (shrink)

A considerable section of the population in India accesses the services of individual private medical practitioners (PMPs) for primary level care. In rural areas, these providers include MBBS doctors, practitioners of alternative systems of medicine, herbalists, indigenous and folk practitioners, compounders and others. This paper describes the profile, knowledge and some practices of the rural doctor in India and then discusses the reasons for lack of equity in health care access in rural areas and possible solutions to the problem.

Background: Homeless persons in the United States have disproportionately high rates of illness, injury, and mortality and tend to believe that the quality of their end-of-life care will be poor. No studies were found as to whether nurses or nursing students require moral courage to help homeless persons or members of any other demographic complete advance directives. Research hypothesis: We hypothesized that baccalaureate nursing students require moral courage to help homeless persons complete advance directives. Moral courage was defined as a (...) trait of a person or an action that overcomes fears or other challenges to achieve something of great moral worth. Research design: The hypothesis was investigated through a qualitative descriptive study. Aside from the pre-selection of a single variable to study (i.e. moral courage), our investigation was a naturalistic inquiry with narrative hues insofar as it attended to specific words and phrases in the data that were associated with that variable. Participants and research context: A total of 15 baccalaureate nursing students at a public university in the United States responded to questionnaires that sought to elicit fears and other challenges that they both expected to experience and actually experienced while helping homeless persons complete advance directives at a local, non-profit service agency. Ethical considerations: The study was approved by the Internal Review Board of the authors’ university, and each participant signed an informed consent form, which stated that the study involved no reasonably foreseeable risks and that participation was voluntary. Findings: Before meeting with homeless persons, participants reported that they expected to experience two fears and a challenge: fear of behaving in ways that a homeless person would deem inappropriate, fear of discussing a homeless person’s dying and death, and the challenge of adequately conveying the advance directive’s meaning and accurately recording a homeless person’s end-of-life wishes. In contrast, after their meetings with homeless persons, relatively few participants reported having encountered those obstacles. So, while participants required moral courage to assist homeless persons with advance directives, they required greater moral courage as they anticipated their meetings than during those meetings. Discussion: Our study breaks new ground at the intersection of nursing, moral courage, and advance directives. It might also have important implications for how to improve the training that US nursing students receive before they provide this service. Conclusion: Our results cannot be generalized, but portions of our approach are likely to be transferable to similar social contexts. For example, because homeless persons are misunderstood and marginalized throughout the United States, our design for training nursing students to provide this service is also likely to be useful across the United States. Internationally, however, it is not yet known whether our participants’ fears and the challenge they faced are also experienced by those who assist homeless persons or members of other vulnerable populations in documenting healthcare wishes.

Stem cells are likely to be used as an alternate source of biological material for neural transplantation to treat Parkinson’s disease in the not too distant future. Among the several ethical criteria that must be fulfilled before proceeding with clinical research, a favourable benefit to risk ratio must be obtained. The potential benefits to the participant and to society are evaluated relative to the risks in an attempt to offer the participants a reasonable choice. Through examination of preclinical studies transplanting (...) stem cells in animals and the transplantation of fetal tissue in patients with Parkinson’s disease, a current set of potential benefits and risks for neural transplantation of stem cells in clinical research of Parkinson’s disease are derived. The potential benefits to research participants undergoing stem cell transplantation are relief of parkinsonian symptoms and decreasing doses of parkinsonian drugs. Transplantation of stem cells as a treatment for Parkinson’s disease may benefit society by providing knowledge that can be used to help determine better treatments in the future. The risks to research participants undergoing stem cell transplantation include tumour formation, inappropriate stem cell migration, immune rejection of transplanted stem cells, haemorrhage during neurosurgery and postoperative infection. Although some of these risks are general to neurosurgical transplantation and may not be reduced for participants, the potential risk of tumour formation and inappropriate stem cell migration must be minimised before obtaining a favourable potential benefit to risk calculus and to provide participants with a reasonable choice before they enrol in clinical studies.

This paper is going to re-read Imam Mohammad al-Ghazali’s moral ideas in order to find the responses to the questions of moral psychology. Al-Ghazali, following the Greek and Islamic philosophers, relates each virtue or vice to a particular faculty in man’s soul. Moreover, following the Asharites, he considers the basis of moral good and badness to be religious. Furthermore, having mentioned al-Ghazali and Hume’s opinions as well as their similarities, this writing explains why al-Ghazali’s view on the moral motivation has (...) not encountered Hume’s objections. And finally, it presents the differences between al-Ghazali and the Greek philosophers’ views on virtues and vices as well as evaluates al-Ghazali’s psychological opinions in ethics. (shrink)
