High-spin states in the odd-odd N = Z nucleus Co-54 have been investigated by the fusion-evaporation reaction Si-28(S-32,1 alpha 1p1n)Co-54. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1 pi neutron detector array. A significantly extended excitation scheme of Co-54 is presented, which includes a candidate for the isospin T = 1, 6(+) state of the 1f(7/2)(-2) multiplet. The results are compared to large-scale shell-model (...) calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations. (shrink)

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

Subjects and Simulations presents essays focused on suffering and sublimity, representation and subjectivity, and the relation of truth and appearance through engagement with the legacies of Jean Baudrillard and Philippe Lacoue-Labarthe.

This edition of Giovanni Pico della Mirandola’s “De ente et uno” (“On being and the one”) offers for the first time a key text for the reformation of metaphysics in Renaissance philosophy in German translation. The Latin text is added. The detailed introduction and careful commentary reveal the guiding points Pico has set with this work.

Criticism of the deductive model of explanation continues. In a recent article, “Truisms as the Grounds for Historical Explanations,” Professor Michael Scriven hangs a great many critical points from the distinction between explanations and their justifications. I should like to examine his proposal with a view to showing that in so far as this distinction can be made, it cannot be used as a basis of criticisms of the deductive or covering law model, as it was originally outlined by Professor (...) Carl G. Hempel. (shrink)

Some assertions give rise to the acquaintance inference: the inference that the speaker is acquainted with some individual. Discussion of the acquaintance inference has previously focused on assertions about aesthetic matters and personal tastes (e.g. 'The cake is tasty'), but it also arises with reports about how things seem (e.g. 'Tom seems like he's cooking'). 'Seem'-reports give rise to puzzling acquaintance behavior, with no analogue in the previously-discussed domains. In particular, these reports call for a distinction between the specific acquaintance (...) inference (that the speaker is acquainted with a specific individual) and the general acquaintance inference (that the speaker is acquainted with something or other of relevance). We frame a novel empirical generalization -- the specific with stage-level generalization -- that systematizes the observed behavior, in terms of the semantics of the embedded 'like'-clause. We present supporting experimental work, and explain why the generalization makes sense given the evidential role of 'seem'-reports. Finally, we discuss the relevance of this result for extant proposals about the semantics of 'seem'-reports. More modestly, it fills a gap in previous theories by identifying which reports get which of two possible interpretations; more radically, it suggests a revision of the kind of explanation that should be given for the acquaintance behavior in question.

L'article adopte un point de vue plus systématique qu'historique sur la métaphysique de Christian Wolff et, en particulier, sur sa théorie de la conscience. Il s'intéresse à des écrits de controverse de l'époque, impliquant Lange, Ludovici et un certain Bequignole, officier dans l'armée prussienne. Ce dernier, bien qu'il ne fût pas un philosophe professionnel, a relevé dans la Métaphysique allemande quelques défauts graves de la théorie wolffienne de la conscience. En refusant d'attribuer la raison aux bêtes et en décrivant la (...) mémoire du chien en termes très proches de la mémoire de soi propre aux personnes, le philosophe de Halle n'a pas pu éviter de se contredire. The paper adopts a more systematic than historical point of view on Christian Wolff's metaphysics and, in particular, on his theory of consciousness. It is interested in controversial writings of those days with reference e.g. to Lange, Ludovici and an officer of the Prussian army so-called Bequignole ; the latter, though he tvas no professional philosopher, found a few serious defects of Wolff's theory of consciousness in the latter's German Metaphysics. By refusing to grant reason to animals and by describing the dog's memory in terms very close to the self memory specific to persons, Wolff couldn't avoid contradicting himself. (shrink)

La intención de nuestro trabajo ha sido la de exponer la anticipación pragmática que realizara U. Eco en "Obra abierta", ya en 1962, insustituible para una hermenéutica de la obra de arte, que pone especial atención en la instancia del usuario, imaginando un lector modelo ejerciendo actos de libertad consciente para una obra que se presenta como abierta, a veces en movimiento, e invariablemente como metáfora epistemológica de nuestro tiempo.Hemos presentado algunos aportes que sobre el contexto han realizado lingüistas, aportes (...) que pueden trasladarse satisfactoriamente al campo de la estética, como adecuado límite a una multiplicidad infinita de sentido de la obra de arte, para servirle de gran utilidad, a pesar de que ciertas teorías ya clásicas de la Estética puedan haber pensado, en su momento, lo contrario.Finalmente, buscando algo diferente, con relación a los efectos de las obras de arte en sus gozadores, provocados intencionalmente por sus autores, hemos insertado ejemplos de experiencias propias y disímiles entre las mismas, como nos sucedió con J. L. Borges y con la banda de rock Los Redonditos de Ricota. (shrink)

The Prologue offers an overview of the Reformation of method from Augustine of Hippo through to the Ramist movement, providing an orientation to the rest of the book. It highlights and explains an important nexus of Realism, exemplarism and illumination fundamental to Ramism. Beginning with Augustine it shows how these themes coalesced into a distinctive Christian philosophy taken up and refined by Franciscans such as Bonaventure of Bagnoregio and John Duns Scotus, as well as by Ramon Lull, the Franciscan-inspired encyclopaedist. (...) It traces the continuation of this methodological impulse into the Platonism and Christian humanism of the Renaissance, highlighting especially the topical and Realist (Scotistic) reform of logic pioneered by Lorenzo Valla and Rudolph Agricola. It concludes by showing the reception of this topical and biblical reform in Philipp Melanchthon and the movement of Reformed scholasticism, revealing Reformed Scotism and Christian philosophy as important preconditions for Ramism.

In the recent past, several papers have pointed to the possibility that tumour removal generates a permissive environment in which tumour growth is potentiated. This phenomenon has been coined “perioperative tumour growth” and whilst it represents a departure in terms of our attitude to the surgical process, this concept was first hinted at by Paget1Sir James Paget (1814–1899) was a surgeon and physiologist who is widely held (along with Rudolph Virchow) to be the father of the science of pathology. (...) Paget described Paget's disease of the nipple as well as Paget's disease of bone. himself. Despite this, the time interval immediately before and after cancer surgery (i.e. the perioperative period) remains an underutilised interval during which chemotherapeutic regimens are rarely implemented. Herein, we present a summarised review of the literature that supports the concept that tumour removal may potentiate the growth of residual neoplastic disease. We also outline current knowledge regarding underlying mechanisms and in this manner highlight potential therapeutic entry points. Finally, we emphasise the urgent need for trials of agents that could protect patients against the harmful host–tumour interactions that may occur during the perioperative period.

The present study has two goals: to explore elementary students’ understanding of evidence and the ways they deploy it to construct arguments, and to examine whether eliciting their concept of evidence during argumentation improves students’ evidence-based reasoning. Individual semi-structured interviews were conducted with 4th and 6th graders in a public school in Mexico. We found significant differences between groups regarding the concept of evidence, with better performance in the older group. A positive correlation between the concept of evidence and the (...) quality of evidence-based reasoning was found. Also, three performance profiles were observed after eliciting the concept of evidence when grade was excluded as a factor. Results suggest that the concept of evidence plays an essential role in developing argumentative competence in pre-adolescence. (shrink)

This is the first complete, one-volume English translation of the ancient Chinese text Xunzi, one of the most extensive, sophisticated, and elegant works in the tradition of Confucian thought. Through essays, poetry, dialogues, and anecdotes, the Xunzi articulates a Confucian perspective on ethics, politics, warfare, language, psychology, human nature, ritual, and music, among other topics. Aimed at general readers and students of Chinese thought, Eric Hutton’s translation makes the full text of this important work more accessible in English than ever (...) before. Named for its purported author, the Xunzi has long been neglected compared to works such as the Analects of Confucius and the Mencius. Yet interest in the Xunzi has grown in recent decades, and the text presents a much more systematic vision of the Confucian ideal than the fragmented sayings of Confucius and Mencius. In one famous, explicit contrast to them, the Xunzi argues that human nature is bad. However, it also allows that people can become good through rituals and institutions established by earlier sages. Indeed, the main purpose of the Xunzi is to urge people to become as good as possible, both for their own sakes and for the sake of peace and order in the world. In this edition, key terms are consistently translated to aid understanding and line numbers are provided for easy reference. Other features include a concise introduction, a timeline of early Chinese history, a list of important names and terms, cross-references, brief explanatory notes, a bibliography, and an index.

There is a conflict over whether Christian ministry and theological education should be pursued with an expectation for economic survival. The rise of Christian ministry practice emphasising wealth and prosperity has heightened commodification of the Christian ministry. Church ministry and theological education are being used as instruments for economic profit. The link between theological education and Christian ministry, among other things, is that church practices and ministry expressions reflect the underlying theology. In such a situation, this article reflects on the (...) following questions: How are Christian ministry and its undergirding theology being utilised as instruments of economic prosperity in Africa? What is the theological education approach that is employed to support this ministry approach? The article attempts to establish an understanding of ministerial practise that has biblically and theologically informed views of material wealth. It begins by examining the traditional missionary model of ministry as a sacrificial act and responses by African clergy. This is followed by examination of the development of the view of ministry as a means of economic survival and commodification of ministry and theological education in Africa. It concludes by providing an evaluation and proposing a way forward. (shrink)

Poverty has continued to be an enormous challenge for Africa. Immoral political decisions and tactics have led to the continued suffering of the landless poor in the city of Harare. With no consideration for the dignity of people, the government of Zimbabwe through Operation Murambatsvina demolished shelters belonging to the poor in the city a decade and half ago. To this day, most of the victims of this destruction still lack adequate accommodation. The majority urban poor have been excluded from (...) the community and inhabit shanty towns around Harare. Deprived of justice, the poor are alienated from their right to land, nourishment and dignified life. This complete disregard for life and African community values ought to be challenged. Ubuntu moral theory presents necessary guiding principles for human progress that achieves genuine harmony and equality among all people. In light of the experiences of deadly but preventable poverty in Harare, the will-to-live for all requires confirmation. Every human being is endowed with irrevocable intrinsic worth. The elimination of poverty requires practical philosophical resolutions that are driven by sincere respect for human life. (shrink)
