La doctrina de la Proliferación teórica de Paul Karl Feyerabend ha sido interpretada por sus especialistas como un intento de salvaguardar el ideal del progreso científico. Aunque tales estudios hacen justicia, en parte, a la intencionalidad de nuestro filósofo no explicitan la crítica fundamental que implica para Feyerabend el pluralismo teórico. La proliferación teórica constituye en sí misma una reductio ad absurdum de los distintos intentos del positivismo lógico y del racionalismo crítico por definir la ciencia a expensas de lo metafísico. Este artículo presenta la proliferación teórica como una reivindicación del papel positivo que ocupa la metafísica en el quehacer científico. Se consigna la defensa que hace Feyerabend de la metafísica en cuanto que ésta constituye la posibilidad de superar el conservadurismo conceptual, aumentar de contenido empírico de la ciencia y recuperar el valor descriptivo de las teorías científicas.

En su comentario a la Ética a Nicómaco, Averroes se ocupó del pasaje donde Aristóteles distingue entre las cosas que son justas por naturaleza y aquéllas que lo son en virtud de la ley (V, 7 1134b18-1135a5). Su comentario es particularmente breve, pero plantea algunas dificultades importantes, como su alusión a un derecho naturale legale, que, según Leo Strauss, vendría a ser simplemente un derecho positivo de aceptación general. En este artículo se busca caracterizar lo justo natural y lo justo positivo en el comentario de Averroes y mostrar el alcance de la variación de los criterios propios de la justicia positiva.

This paper explores the problem of the synthesis between vitalism and rationalism, in contemporary philosophy. With this aim, we compare the intellectual careers of Georges Canguilhem (1904-1995) and José Ortega y Gasset (1883-1955). We contrast their conceptions of philosophy as “hybrid” knowledge, closely related to science, as well as their points of view on Vitalism, anthropology, the technique and the perspectivism. To avoid that comparison is purely abstract and ahistorical, we use the method of the sociology of philosophy. This forces us to locate both paths in their respective philosophical fields and generational units, also according to his social background and professional career.

The subiculum is in a pivotal position governing the output of the hippocampal formation. Despite this, it is a rather under-explored and sometimes ignored structure. Here, we discuss recent data indicating that the subiculum participates in a wide range of neurocognitive functions and processes. Some of the functions of subiculum are relatively well-known-these include providing a relatively coarse representation of space and participating in, and supporting certain aspects of, memory (particularly in the dynamic bridging of temporal intervals). The subiculum also participates in a wide variety of other neurocognitive functions too. however. Much less well-known are roles for the subiculum, and particularly the ventral subiculum, in the response to fear, stress and anxiety, and in the generation of motivated behaviour (particularly the behaviour that underlies drug addiction and the response to reward). There is an emerging suggestion that the subiculum participates in the temporal control of behaviour. It is notable that these latter findings have emerged from a consideration of instrumental behaviour using operant techniques; it may well be the case that the use of the watermaze or similar spatial tasks to assess subicular function (on the presumption that its functions are very similar to the hippocampus proper) has obscured rather than revealed neurocognitive functions of subiculum. The anatomy of subiculum suggests it participates in a rather subtle fashion in a very broad range of functions, rather than in a relatively more isolated fashion in a narrower range of functions, as might be the case for

A new kind of photographic representation, called movement-image is proposed and discussed to record the visual experience of the journey through urban highways. It consists of performing long exposure photographic shots while the track is traversed, thus registering a time-panorama which includes landscape signs and inner spaces of the ways involved. This proposal is linked to the limitations of representing these expressways, if they are understood as structures of instrumental origin, where the resulting experience comes from moving at high speed through the territory. In al almost all cases the aesthetic approach or urban integration with the city and landscape are excluded. In this sense, although such structures may be an opportunity to collect, build and colonize the urban landscape, the lack of adequate representation of the phenomenon causes a difficulty in its understanding and transformation. The options for representation using photography is assumed, knowing its own particular tradition in the use of long exposures, for the expression of the mobile, and the multiple visual attention, divided or weakened.

Reconstruction of hydroclimate variability is an important part of understanding natural climate change on decadal to millennial timescales. Peatland records reconstruct 'bog surface wetness' (BSW) changes, but it is unclear whether it is a relative dominance of precipitation or temperature that has driven these variations over Holocene timescales. Previously, correlations with instrumental climate data implied that precipitation is the dominant control. However, a recent chironomid inferred July temperature record suggested temperature changes were synchronous with BSW over the mid-late Holocene. This paper provides new analyses of these data to test competing hypotheses of climate controls on bog surface wetness and discusses some of the distal drivers of large-scale spatial patterns of BSW change. Using statistically based estimates of uncertainty in chronologies and proxy records, we show a correlation between Holocene summer temperature and BSW is plausible, but that chronologies are insufficiently precise to demonstrate this conclusively. Simulated summer moisture deficit changes for the last 6000 years forced by temperature alone are relatively small compared with observations over the 20th century. Instrumental records show that summer moisture deficit provides the best explanatory variable for measured water table changes and is more strongly correlated with precipitation than with temperature in both Estonia and the UK. We conclude that BSW is driven primarily by precipitation, reinforced by temperature, which is negatively correlated with precipitation and therefore usually forces summer moisture deficit in the same direction. In western Europe, BSW records are likely to be forced by changes in the strength and location of westerlies, linked to large-scale North Atlantic ocean and atmospheric circulation.

"In this special issue's opening essay, Martin Dowling devotes almost half of "'Thought-Tormented Music': Joyce and the Music of the Irish Revival" to what he calls "the situation of music in the Irish literary revival." He focuses chiefly on 1904, which was both an intensely productive period for the revival movement and a year chock-full of crucial events and decisions for Joyce. Drawing on the works of Pierre Bourdieu and Jaques Lacan, Dowling explores the revivalists' efforts to "de-anglicize" Irish music, to remove foreign influences that distorted the "pure tradition of Irish song," and to achieve an improbable harmony between the music favoured by the disappearing Anglo-Irish aristocracy and the Irish-speaking peasantry. Inevitably, disputes occurred over what constituted "authentic" Irish music. Factions quarrelled over whether pristine Irish music existed in the Atlantic seaboard or more inland; whether "authentic" songs were sung with or without instrumental accompaniment; and whether the piano, rather than the traditional harp, was a legitimate instrument of accompaniment. Having delineated the historical and theoretical context, Dowling offers a richly detailed analysis of Joyce's story "A Mother." He reveals how almost every element in the story--from the Eire Abu Society to the Antient Concert Rooms, from the conflict between Mrs. Kearney and Hoppy Holohan to the plight of Kathleen Kearney--is charged with meaning by the subtextual conflicts of the revivalists' agenda. Dowling explains also the "authenticity" in Joyce's depiction of vocal performances of "The Lass of Aughrim" in "The Dead" and "The Croppy Boy" in "Sirens," which he calls two "true gems" of authentic Irish music." --Introduction by Charles Rossman and Alan W. Friedman, Guest Editors, pp. 409-410

In Northern Ireland and Israel schools have long been recognised as key sites for addressing the problems of poor intergroup relations (see Dunn, 1990; Murray, 1985). The developments of integrated schools which welcome members of the main communities have been regarded as a key development which is likely to be instrumental in promoting more harmonious relations. Although the schools have been regarded in the media as a ‘good news story’ the qualitative processes through which teachers within these schools foster reconciliation is not always clear. The purpose of this chapter is thus to explore this question by drawing on contact theory and interviews with teachers in Northern Ireland and Israel.

Public support for private R&D and innovation is part of most national and regional innovation support regimes. In this article, we estimate the effect of public innovation support on innovation outputs in Ireland and Northern Ireland. Three dimensions of output additionality are considered: extensive additionality, in which public support encourages a larger proportion of the population of firms to innovate; improved product additionality, in which there is an increase in the average importance of incremental innovation; new product additionality, in which there is an increase in the average importance of more radical innovation. Using an instrumental variable approach, our results are generally positive, with public support for innovation having positive, and generally significant, extensive, improved and new product additionality effects. These results hold both for all plants and indigenously owned plants, a specific target of policy in both jurisdictions. The suggestion is that grant aid to firms can be effective in both encouraging firms to initiate new innovation and improve the quality and sophistication of their innovation activity. Our results also emphasize the importance for innovation of in-house R&D, supply-chain linkages, skill levels and capital investment, all of which may be the focus of complementary policy initiatives.

Brass bands are among the most widespread instrumental ensembles in the world, yet there has been little academic interest in them. This is because they stand in a space between art and authenticity, as their repertoires are thought to lack artistic merit while their military legacies have disconnected them from the ‘authentic’ music of ‘the people’. This paper aims to show how it is precisely this intermediary position which has attracted the attention of some (ethno)musicologists, and a growing number of studies demonstrate the analytic potential of this musical universe in a wide range of contexts across the globe.

In 1700 few Irishwomen were literate. Most lived in a rural environment, rarely encountered a book or a play or ventured much beyond their own domestic space. By 1960 literacy was universal, all Irishwomen attended primary school, had access to a variety of books, magazines, newspapers and other forms of popular media and the wider world was now part of their every-day life. This study seeks to examine the cultural encounters and exchanges inherent in this transformation. It analyses reading and popular and consumer culture as sites of negotiation of gender roles. This is not an exhaustive treatment of the theme but focusses on three key points of cultural encounter: the Enlightenment, emigration and modernism. The writings and intellectual discourse generated by the Enlightenment was one of the most influential forces shaping western society. It set the agenda for scientific, political and social thought for the eighteenth and nineteenth centuries. The migration of peoples to north America was another key historical marker in the development of the modern world. Emigration altered and shaped American society as well as the lives of those who remained behind. By the twentieth century, aesthetic modernism suspicious of enlightenment rationalism and determined to produce new cultural forms developed in a complex relationship with the forces of industrialisation, urbanisation and social change. This study analyses the impact of these three key forces in Western culture on changing roles and perceptions of Irish women from 1700 to 1960.

This article adopts an ecological view of digital musical interactions, first considering the relationship between performers and digital systems, and then spectators’ perception of these interactions. We provide evidence that the relationships between performers and digital music systems are not necessarily instrumental in the same was as they are with acoustic systems, and nor should they always strive to be. Furthermore, we report results of a study suggesting that spectators may not perceive such interactions in the same way as performances with musical instruments. We present implications for the design of digital musical interactions, suggesting that designers should embrace the reality that digital systems are malleable and dynamic, and may engage performers and spectators in different modalities, sometimes simultaneously.

RNA polymerase I (Pol I) produces large ribosomal RNAs (rRNAs). In this study, we show that the Rpa49 and Rpa34 Pol I subunits, which do not have counterparts in Pol II and Pol III complexes, are functionally conserved using heterospecific complementation of the human and Schizosaccharomyces pombe orthologues in Saccharomyces cerevisiae. Deletion of RPA49 leads to the disappearance of nucleolar structure, but nucleolar assembly can be restored by decreasing ribosomal gene copy number from 190 to 25. Statistical analysis of Miller spreads in the absence of Rpa49 demonstrates a fourfold decrease in Pol I loading rate per gene and decreased contact between adjacent Pol I complexes. Therefore, the Rpa34 and Rpa49 Pol I–specific subunits are essential for nucleolar assembly and for the high polymerase loading rate associated with frequent contact between adjacent enzymes. Together our data suggest that localized rRNA production results in spatially constrained rRNA production, which is instrumental for nucleolar assembly.

Punitive public attitudes cannot be easily explained by pointing to instrumental concerns (e.g., fear of crime, personal victimization, or rea or perceived levels of crime). Instead, numerous observers have suggested that public punitiveness is more a symptom of free-floating anxieties and insecurities resulting from social change than a rational response to crime problems. We argue that these public concerns might be better understood by drawing on the insights of psychoanalytic theory, and we review relevant theoretical work to that effect.

Design: Cross-sectional qualitative study.

Data sources: Interviews with purposeful sample of 25 recently bereaved parents.

Methods: Semi-structured in-depth interviews.

Results: Four analytically distinct processes were identified in the responses of parents to the death of a child. These are referred to as ‘piloting’, ‘providing’, ‘protecting’ and ‘preserving’. Regardless of individual circumstances, these processes were integral to all parents’ coping, enabling an active ‘doing’ for their child and family throughout the trajectory of their child's illness and into bereavement.

Conclusions: Facilitating the capacity of parents to ‘do’ is central to coping with the stress and uncertainty of living through the death of a child. The provision of informational, instrumental and emotional support by health care professionals in the context of ‘doing’ is core to quality palliative care.
