La autora reflexiona, a partir de esta novela de Humberto Salvador, sobre la razón de ser del texto novelesco. Resalta la intención del ecuatoriano de presentar una novela que busca integrar distintos discursos sociales, ensamblados como al azar, cuestionan diversas definiciones canónicas, tanto en lo literario como en lo social. Salvador prioriza en ellas el mostrar «cómo» se escribe una novela, y no el acabarla o dar por cerrado el producto. Concebido así, el texto novelesco se vuelve infinito, al igual que sus posibles lecturas: cada una produce una novela diferente, que jamás resulta definitiva.

El autor entrevista al narrador guayaquileño Jorge Velasco Mackenzie, quien responde sobre su oficio de escritor. Velasco sostiene que sufre con sus personajes y agoniza cuando estos mueren. Mira a Tatuaje de náufragos como un homenaje a un bar generacional, a una época y una forma de ser artista que ya no existen más, sería la autopsia de una generación y de la ciudad. Velasco sostiene que el poeta Fernando Nieto no solo fue un animador de la bohemia del Montreal, el fundador de Sicoseo, sino un hombre que sabía mucho, y un hombre generoso en lo personal, admira la posición de Nieto frente al mundo, frente a la literatura. En los escritos de Velasco siempre está Guayaquil, porque es el lugar donde nació y es el único donde puede vivir. Podría decirse que escribir sobre Guayaquil es su proyecto estético. Considera al Montreal como un lugar vivo, abierto, con sus personajes y su rocola antigua, lo evocó así toda su vida y a lo largo del libro intentó devolverle ese esplendor.

Purpose – The purpose of this paper is to introduce three fundamental concepts of Jewish thought that act as the basis of society. The authors use these concepts to examine standard organisational behaviour in modern society and highlight basic shortcomings of modern organisational thought. Design/methodology/approach – The methodology is a conceptual/theoretical one. Findings – The paper reveals the shortcomings of modern organisation and its members of not accepting the three fundamental concepts that underpin Jewish thought and, in turn, the unwillingness of the organisation's members to resume responsibility. Originality/value – This paper highlights three fundamental values from Jewish thought that are applicable to all, using a domain of knowledge that scholars usually use in research into management.

The research which underpins this paper began as a doctoral project exploring archaic beliefs concerning Otherworlds and Thin Places in two particular landscapes - the West Coast of Wales and the West Coast of Ireland. A Thin Place is an ancient Celtic Christian term used to describe a marginal, liminal realm, beyond everyday human experience and perception, where mortals could pass into the Otherworld more readily, or make contact with those in the Otherworld more willingly. To encounter a Thin Place in ancient folklore was significant because it engendered a state of alertness, an awakening to what the theologian John O’ Donohue (2004: 49) called “the primal affection.” These complex notions and terms will be further explored in this paper in relation to Education. Thin Teaching is a pedagogical approach which offers students the space to ruminate on the possibility that their existence can be more and can mean more than the categories they believed they belonged to or felt they should inhabit. Central to the argument then, is that certain places and their inhabitants can become revitalised by sensitively considered teaching methodologies. This raises interesting questions about the role spirituality plays in teaching practice as a tool for healing in the twenty first century.

This chapter focuses on critical responses to Alfred Hitchcock’s Rear Window, especially their construction of disability. The suggestion is that such criticism takes the disabled body to be both necessary and superfluous to the meaning of the film, a difficulty that, I argue, can be read more widely within film theory. Ever since Christian Metz’s ‘the Imaginary Signifier’, the condition of being ‘bound to a wheelchair’ is understood to have a resonance for theories of film spectatorship, but only ever in a sense that does away with the wheelchair as a mark of difference.

Nanostrucured europium oxide and hydroxide films were obtained by pulsed Nd:YAG (532 nm) laser ablation of a europium metallic target, in the presence of a 1 mbar helium buffer atmosphere. Both the produced film and the ambient plasma were characterized. The plasma was monitored by an electrostatic probe, for plume expansion in vacuum or in the presence of the buffer atmosphere. The time evolution of the ion saturation current was obtained for several probe to substrate distances. The results show the splitting of the plume into two velocity groups, being the lower velocity profile associated with metal cluster formation within the plume. The films were obtained in the presence of helium atmosphere, for several target-to-substrate distances. They were analyzed by Rutherford backscattering spectrometry, x-ray diffraction, and atomic force microscopy, for as-deposited and 600 degrees C treated-in-air samples. The results show that the as-deposited samples are amorphous and have chemical composition compatible with europium hydroxide. The thermally treated samples show x-ray diffraction peaks of Eu(2)O(3), with chemical composition showing excess oxygen. Film nanostructuring was shown to be strongly correlated with cluster formation, as shown by velocity splitting in probe current versus time plots. (C) 2010 American Vacuum Society.

To comprehend the recent Brookhaven National Laboratory experiment E788 on (4)(Lambda)He, we have outlined a simple theoretical framework. based on the independent-particle shell model, for the one-nucleon-induced nonmesonic weak decay spectra. Basically, the shapes of all the spectra are tailored by the kinematics of the corresponding phase space, depending very weakly on the dynamics, which is gauged here by the one-meson-exchange potential. In spite of the straightforwardness of the approach a good agreement with data is achieved. This might be an indication that the final-state-interactions and the two-nucleon induced processes are not very important in the decay of this hypernucleus. We have also found that the pi + K exchange potential with soft vertex-form-factor cutoffs (Lambda(pi) approximate to 0.7 GeV, Lambda(K) approximate to 0.9 GeV), is able to account simultaneously for the available experimental data related to Gamma(p) and Gamma(n) for (4)(Lambda)H, (4)(Lambda)H, and (5)(Lambda)H.

The (2)H(d,p)(3)H and (2)H(d,n)(3)He reactions have been indirectly studied by means of the Trojan Horse Method applied to the quasi-free (2)H((3)He, p(3)H)(1)H (2)H((3)He, n(3)He)(1)H reaction at 18 MeV of beam energy. This is the first experiment where the spectator (here (1)H) has been detected in coincidence with the charged participant, avoiding the limitations of standard neutron detectors. The d - d relative energy has been measured from 1.5 MeV down to 2 keV, at center of mass angles from 40A degrees to 170A degrees. Indirect angular distributions are compared with the direct behaviour in the overlapping regions.

Most approaches to Duffy’s work have been a feminist reading of poetry, focusing on the portrayal of women within the theoretical framework of feminism. However, little attention has been paid to the religious elements in Duffy’s work, something that Duffy herself has recognized. This essay will therefore focus on the centrality of religion in Duffy’s work, and will argue that her poems constitute an arena where religion is redefined and female experience and theology are reconciled. The poems under focus, “Delilah”, “Salome”, “Pilate’s wife”, “Pope Joan”, “Mrs Lazarous” and “Queen Herod” are examined in two separate sections: their portrayal of love and sexuality, and their portrayal of motherhood respectively, within the theoretical framework of feminist theology.
