A molecular dynamics (MD) approach which determines automatically the complex magnetic structures in itinerant electron systems is applied to Fe-Cr alloys with use of 250 atoms in a MD unit cell (5×5×5 bcc lattice). It is demonstrated that the Fe-Cr alloys show various complex magnetic structures due to competing interactions: the collinear ferromagnetism (F) of matrix Fe with antiparallel Cr moments beyond 80 at.% Fe, the coexistence of non-collinear structure of Cr and collinear F of Fe between 50 and 75 (...) at.% Fe, the coexistence of broken antiferromagnetism (AF) of Cr and the F of Fe between 25 and 45 at.% Fe, the coexistence of F of Fe and antiferromagnetic long-range order of Cr around 20 at.% Fe, the AF of Cr matrix with non-collinear Fe moments (spin-glass like structure) between 5 and 15 at.% Fe, and the AF below 5 at.% Fe. In the concentration region between 5 and 20 at.% Fe, ferromagnetic Fe pairs which are stabilized with different amplitudes of local moments are found. The magnetic phase diagram and calculated magnetic moments are shown to be consistent with the neutron, Mössbauer, and photoemission experiments. (shrink)

The Bose-Einstein condensation of free relativistic particles [ε=(M 2 c 4 +c 2 p 2 ) 1/2 −Mc 2 ] is studied rigorously. For massless bosons (ε=cp), the condensation transition of third (second) order occurs in2 (3) dimensions (D). The molar heat capacity follows the T 2 (T 3 ) law below the condensation temperature Tc [k B Tc=(2πħ 2 c 2 n/1.645) 1/2 [(π 2 ħ 3 c 3 n/1.202) 1/3 ], reaches4.38 (10.8) R at T=Tc, and approaches the (...) high-temperature-limit value2 (3) R with no jump (a jump equal to6.75R) in2 (3)D. For finite-mass (M) bosons, the phase transition occurs only in3D with the condensation temperature Tc always smaller than that of the corresponding nonrelativistic bosons [ε=(2M) −1 p 2 ]. If the mass M is reduced to zero, the condensation temperature Tc grows monotonically and reaches eventually that of massless relativistic bosons. This mass-dependence of Tc is therefore distinct from the case of nonrelativistic bosons, where Tc grows to infinity as M →0. A brief discussion is given for a possible connection with the normal-to-super transition of the independently moving Cooper pairs (bosons). (shrink)

The Montessori Method is accepted as an alternative education model today. Although it was spread out in USA at the beginning of the 20th century, it is currently used and accepted all over the world. Although its application in pre-education is common, it has also been adopted and applied at different levels. The Montessori method differs from traditional education not only in terms of approach to students, teachers, discipline, and school environment, but also in the way it uses certain materials (...) in its education. According to Maria Montessori, kids should be at the center of education, and the duty of teacher is to observe and guide children. The Montessori method, which is mostly applied in general education, is also used in the education of religion, values, and morals. In this study, besides Maria Montessori's thoughts on general education, her thoughts on religious education are also discussed. This research focuses on Montessori schools in Indiana, United States -. In this study, the qualitative research method and the phenomenological approach are adopted. Observation, interview, and document analysis are used as data collection tools. The subject of the study is the discussion of the Montessori method in terms of research results in religion, values and moral education and Montessori’s point of view on the subject. All participants, who work as instructors in Montessori schools, determined by maximum diversity and snowball sampling, Observation in Montessori schools and the program of one of them is used as an aid in the interpretation of the research findings.

All these activities of living beings, and the functioning of their organs, and the functioning of instruments demand a teleological explanation. Why do human beings toil? Why do living beings try to maintain the activities of the organism? What are the functions of specific organs or instruments? Intelligible answers can be given in teleological terms. Of course, one could ask many questions about these situations that would not require the teleological explanation; for example, questions concerning the mechanical structure of living (...) beings or of instruments. Yet this fact would not eliminate the legitimacy nor the utility of the teleological category. (shrink)

The ArgumentYehuda Halevi'sKuzariwas written in response to the challenge posed to Judaism by a highly spiritual, nondenominational philosophy. Science, especially that embodied in the Hellenistic heritage, was a major component of philosophy; thus, if for no other reason than to make Judaism a serious competitor, Halevi had to show that the Jewish tradition as well possessed a body of scientific knowledge. The superiority of the Jewish teachings was demonstrated chiefly by appeal to the criteria of tradition, consensus, and authority, which, (...) in Halevi's judgement, were in practice the criteria most influential in deciding scientific opinion. Despite the rather unique setting for the book, and the wide range of stances Halevi develops, theKuzariwas rather quickly and smoothly absorbed into the mainstream of Jewish religious thought.

This article examines the impact of traditional Chinese culture on organ donation from the perspective of Confucianism, Buddhism, and Taoism. In each of these cultural systems, it appears that there are some particular sayings or remarks that are often taken in modern Chinese society to be contrary to organ donation, especially cadaveric organ donation. However, this article argues that the central concerns of Buddhism, Confucianism, and Taoism are “great love,” “ren,” and “dao,” which can be reasonably interpreted to support organ (...) donation. The author understands that each cultural system, in order to play its cultural function, must have its central concerns as well as relevant ritual practices (li) that incarnate its religious and ethical commitments. That is, each plays a general cultural role, which influences organ donation in particular not merely through abstract or general ethical principles and teachings, but through a combination of ethical teachings and the forming of particular ritual practices. This article contends that the primary reason Chinese individuals fail to donate sufficient cadaveric organs for transplantation is not because particular remarks or sayings from each of these systems appear to conflict with donation. Neither is it that the central concerns of these systems cannot support cadaveric donation. Rather, it is that modern Chinese individuals have failed to develop and secure relevant ritual practices that support the central concerns of organ transplantation. The article concludes that in order to promote more donations, there is a need to form relevant ritual practices supporting organ donation in conformity with the central concerns of these cultural systems.

Following a discussion of some historical roots of conscience, we offer a systematized version of reflective equilibrium. Aiming at a comprehensive methodology for bioethical deliberation, we develop an expanded variant of reflective equilibrium, which we call ‘triangular reflective equilibrium’ and which incorporates insights from hermeneutics, critical theory and narrative ethics.We focus on a few distinctions, mainly between methods of justification in ethics and the social practice of bioethical deliberation, between coherence in ethical reasoning, personal integrity and consensus formation, and between (...) political and moral deliberation.The ideal of deliberation is explicated as a sharing of conscience within a special commitment to sincerity and openness to persuasion. Personal growth in wisdom is an indirect by-product of the continuous practice of moral deliberation. This is explicated in the light of Sternberg's balance theory of wisdom and in the context of medicine as a profession embodying altruistic responsibilities of care in democratic and pluralistic societies.

This study presents an exploration of the belief changes of prospective teachers through social co-constructivist teaching. The future presumed in-class teaching orientations of the PTs were also estimated by metaphor analysis. A case study was conducted to monitor the belief changes of the PTs and estimate their probable in-class practices. The participants were six PTs involved in a certification in education programme. The data were gathered from the following different sources; interviews, written reflections and metaphor explanations. The data that were (...) analysed interpretatively and specific parts of the analysed data were subjected to quantification. The PTs held considerably conventional and idealistic teaching beliefs prior to the implementations. The PTs improved their reasoning and enlarged their conceptualisations regarding teaching and learning after the implementations. Five types of teaching belief typologies displaying inherently sophisticated nature of the beliefs were extracted. Some of the PTs appeared to have promise in terms of implementing more learner-centred teaching; however, others preserved their traditional teaching practical orientations. It was considered that changes in teaching beliefs may have motivational and attitudinal dimensions. Finally, capturing the metaphors of the PTs regarding teaching and learning appeared to provide more realistic insights into the estimated in-class practical orientations. (shrink)

ABSTRACT The Daodejing (DDJ) is an ancient Chinese text traditionally taken as a representative Daoist classic expressing a distinctive philosophy from the Warring States Period (403–221 BCE). This essay explicates the ethical dimensions of the DDJ paying attention to issues related to war and peace. The discussion consists of four parts: (1) “naturalness” as an onto‐cosmological argument for a philosophy of harmony, balance, and peace; (2) war as a sign of the disruption of the natural pattern of things initiated by (...) the proliferation of desire; (3) defensive war and appropriate war conduct required when one has to be involved in warfare; and (4) the natural and spontaneous way of living that would prevent war from happening in the first place. This essay attempts to show that what makes the DDJ different from other military texts, or what is called the “art of war corpus” in China is that the discourse of war and warfare in the DDJ is presented via its unique understanding of peace at the personal and social levels. The DDJ is meant to be an inquiry into an effective method to prevent war from happening amid a world full of selfish interests and excessive desires. It proposes that peace is not only a condition in which there is freedom from war and overt violence, but a state of harmony that marks human life and its betterment. (shrink)

The article examines the new discourse on medical professionalism and responsibility through the prism of conflicts among moral values, especially with regard to truth-telling. The discussion is anchored in the renaissance of English-language writing on medical ethics in the 18th century, which paralleled the rise of humanitarianism and the advent of the word “responsibility”. Following an analysis of the meanings of the value of responsibility in general and in medical practice in particular, it is argued that, similarly to the Aristotelian (...) notion of equity, responsibility of care is a second-order value, which corrects virtues, laws and norms in exceptional circumstances. Virtues and practices of the second order, such as responsibility and deliberation, bear especially on professional doctoring, which includes a commitment to give priority to the good of the patient over one’s own good. It is argued that, in situations of conflict, and particularly conflicts between personal moral identity and the good of patients, the fundamental professional commitment is to critical and rational deliberation and to the cultivation of psycho-moral flexibility. This leads indirectly to moral growth and strengthening of professional character. (shrink)

BACKGROUND: Health-based journal clubs have been in place for over 100 years. Participants meet regularly to critique research articles, to improve their understanding of research design, statistics and critical appraisal. However, there is no standard process of conducting an effective journal club. We conducted a systematic literature review to identify core processes of a successful health journal club. METHOD: We searched a range of library databases using established keywords. All research designs were initially considered to establish the body of evidence. (...) Experimental or comparative papers were then critically appraised for methodological quality and information was extracted on effective journal club processes. RESULTS: We identified 101 articles, of which 21 comprised the body of evidence. Of these, 12 described journal club effectiveness. Methodological quality was moderate. The papers described many processes of effective journal clubs. Over 80% papers reported that journal club intervention was effective in improving knowledge and critical appraisal skills. Few papers reported on the psychometric properties of their outcome instruments. No paper reported on the translation of evidence from journal club into clinical practice. CONCLUSION: Characteristics of successful journal clubs included regular and anticipated meetings, mandatory attendance, clear long- and short-term purpose, appropriate meeting timing and incentives, a trained journal club leader to choose papers and lead discussion, circulating papers prior to the meeting, using the internet for wider dissemination and data storage, using established critical appraisal processes and summarizing journal club findings.
