Electron redistribution is the cornerstone of our understanding of chemical reactivity. For the vast majority of organic reactions electrons are assumed to move in pairs providing explanatory mechanisms through the generation of intermediate structures. But for many transformations these discrete steps are idealized constructs, involving intermediates assumed but not empirically justified. This unitary perspective predicated on the curved arrow formalism has resulted in the scenario where for many organic transformations our supposed understanding far surpasses our growing knowledge. Reformulating organic mechanisms (...) to include single electron transfer as a component of, or an alternative to, the prevailing iconic descriptions can provide for a more empirically adequate mechanistic description. In addition using the language of SET presents an opportunity to unify mechanistic concepts under a common donor/acceptor framework. (shrink)

The palaeontological activities of British oil interests in the Middle East from about 1920 to 1970 are described briefly, with emphasis on the nature of the published results. The predominance throughout of micro-palaeontology, due to its utility, is demonstrated. It is shown that, beginning with primary descriptive work on Middle East fossil records, emphasis shifted first to studies of distinctively Middle East palaeontology, and then to results of general application world-wide. It is concluded that the palaeontology of the Middle East (...) is better known today than it would have been without this earlier work, that there has been a feed-back effect on the knowledge of the remainder of the Tethyan area in which the Middle East lies, and that this in turn has stimulated other extra-Tethyan studies as well as contributing to the mainstream of current earth-science research.

As support for his position, Rachlin refers to the writings of Aristotle. However, Aristotle, like many social psychological theorists, would dispute the assumptions that altruism always involves self-control, and that altruism is confined to acts that have group benefits. Indeed, for Aristotle, as for equity theory and sociobiology, justice exists partly to curb the unrestrained actions of those altruists who are a social liability.

How did I raise my arm? The simple answer is that I raised it as a consequence of intending to raise it. A slightly more complicated response would mention the absence of any factors which would inhibit the execution of the intention- and a more complicated one still would specify the intention in terms of a goal (say, drinking a beer) which requires arm-raising as a means towards that end. Whatever the complications, the simple answer appears to be on the (...) right track. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:INDIRECT METHODS IN THEOLOGY: KARL RAHNER AS AN AD HOC APOLOGIST NICHOLAS M. HEALY St. John's University Staten Island, New York THE PURPOSE of this paper is to discuss Karl Rahner's emarks upon, and use of, what he called ' indirect methds ' in theology.1 To my knowledge there has been little analysis, beyond incidental treatment, of Rahner's scattered references to these methods.2 In the following pages I (...) hope to remedy this gap, and argue for two interdependent theses : First, by construing Rahner's own theological practice in the light of his remarks on the indirect methods, an apologetic method can be discerned which could prove useful for contemporary theology. Second, reading Rahner from this perspective indicates that his apologetic method is much more situation-relative and occasionalist than has generally been recognized hitherto. Two Kinds of Apologetics A quick sketch of some aspects of the present theological scene will help make these theses a little clearer and provide some cate1 My discussion of the indirect methods is based primarily upon the following sources: Theological Investigations (New York: Crossroad, 1961-1982) (cited in the text as TI), vol. 6, " A Small Question Regarding the Contemporary Pluralism in the Intellectual Situation of Catholic and the Church", pp. 21-30; vol. 11, "Reflections on Methodology in Theology", pp. 68-114; vol. 16, "A New Task for Theology".

Both these interpreters consider the indirect methods to be synonymous with the transcendental method. They then interpret the former in terms of the latter, misguidedly, I will argue. 613 614 NICHOLAS M. HEALY gories for the following discussion. According to William Placher,8 the contemporary situation in North American theology is often characterized as one in which two rival models of theology are dominant, the revisionist and the post-liberal (Placher, 17-19). Placher discusses many aspects of each model; here I want to look only at those features which bear upon their different conceptions of the nature of apologetics. According to David Tracy, a leading practitioner of the revisionist model, theology in all its forms must be " determined by a relentless drive to genuine publicness ".4 In order to maintain its public character, theology, like any discipline, must develop a preliminary systematic argument by which to ground its possibility and to ·establish its claims to truth and meaningfulness. This initial apologetics uses universal categories and proceeds in accordance with general criteria, functioning in terms, that is, which " all reasonable persons, whether ' religiously involved ' or not, can recognize as reasonable" (Tracy, 57). Usually it takes the form of a foundational explanatory theory of religious discourse which appeals to the universal nature of the deep structures of religious experience. This general theory of religion provides criteria for the subsequent theology, thereby maintaining the latter's relevance for the general, non-Christian public. The theological method considered appropriate is one which attempts systematically to correlate Christian-specific claims with the deep structures of human experience.5 The post-liberal model, by comparison, is more concerned to preserve Christian identity than to maintain the publicness of Christian discourse. The task of theology is not primarily the apologetic one of justifying Christianity to a non-Christian puba Unapologetic Theology: A Christian Voice in a Pluralistic Conversation (Louisville: Westminster/John Knox Press, 1989) (cited as Placher). 4 David Tracy, The Analogical Imagination: Christian Theology and the Culture of Pluralism (New York: Crossroad, 1981), p. 31 (cited as Tracy). 5 See the analyses in, e.g., George A.

Most investigations of musical performance anxiety have employed quantitative methodologies. Whereas such methodologies can provide useful insights into the measurable aspects of the experience in a larger group of participants, the complexity, subtlety and individuality of the emotional experience and the importance of the individual’s interpretation of it are often overlooked. This study employed a phenomenological approach to investigate the lived, subjective experience of performance anxiety, as described in professional musicians’ narratives. Semi-structured interviews with four professional musicians (two males, two (...) females) specializing in Western classical and jazz music genres were conducted and analyzed using Interpretative Phenomenological Analysis (IPA). The analysis revealed the presence of four overarching themes: (1) Intensity of performance anxiety experience, (2) perceived effects, (3) development of coping strategies, and (4) achieving release from anxiety. Findings suggest that the lived experience of performance anxiety is multifaceted, characterized by a physical and a psychological dimension. Interpretative Phenomenological Analysis is a useful research tool that can facilitate our understanding of the subjective experience of performance anxiety (how it is felt and understood at an individual level) and can thus be useful in the development of tailor-made intervention programs for musicians.

Three experiments explored the effects of word problem cueing on debiasing versions of the bat-and-ball problem. In the experimental condition order, participants solved a simpler isomorphic version of the problem prior to solving a standard version that, critically, had the same item-and-dollar amounts. Conversely, in the control condition order, participants solved the standard version prior to solving the isomorph. Across the first 2 experiments, participants cued with the isomorph were more likely to correctly solve the standard version of the problem. (...) In the third experiment, this cueing effect was not replicated, but importantly cued participants were more likely to correctly solve the standard version of the problem with other item-and-dollar amounts, indicating near transfer. Far transfer was evident in faster response times to other problems in the Cognitive Reflection Test following practice. Along with providing converging evidence for the cueing account, these results are consistent with recent attentional debiasing findings. (shrink)
