Alegoría: su pertinencia en la predicación y uso en "La novena maravilla"

En este artículo se focaliza el recurso de la alegoría como método exegético en la composición de los sermones panegíricos de Juan Espinosa Medrano (Perú, siglo XVII). Se traza el recorrido de la alegoría (y las humanidades en general) en relación –siempre tensa– con el cristianismo a lo largo de su historia; y se llega a la Contrarreforma y el uso exacerbado del método en la predicación barroca; particularmente en la oratoria sagrada de Espinosa Medrano, quien abarca elementos diversos y extraídos de distintas fuentes (filosofía natural, mitología clásica, tradición emblemática, relatos bíblicos), a los que hace funcionar como signos de otra verdad mayor, la sagrada. Si bien las preceptivas sagradas impulsaban una predicación más llana y simple, la profusión de alegorías mitológicas, que el autor resemantiza según su interés de guiar la interpretación, pueden explicarse por varias circunstancias, motivos de estudio en este trabajo.

Gaze and power. A post-structuralist interpretation on Perseus’ myth

Gaze hierarchizes, manages and labels reality. Then, according to Foucault, gaze can be understood as a practice of power. This paper is inspired by his theories, and it applies them to one of the most powerful symbolic spheres of Western culture: Greek Myths. Notions such as visibility, invisibility and panopticism bring new light into the story of Perseus and Medusa, and they enable a re-reading of this Myth focused on the different ways of power that emerge from the gaze.

The Challenges of Universalising Religions: the Kabbalah Centre in France and Britain.

The Kabbalah Centre is an offshoot of Judaism which since the 1990s has spread kabbalistic teaching in several countries to a religiously diverse audience. This article compares two European branches of the Kabbalah Centre: the flourishing London Centre, and the Parisian Centre that declined in the late 1990s before closing its doors in 2005. It emphasizes in particular the responses they stirred from the media, anticult movements, Orthodox Judaism and the Jewish population. Ultimately, this case study allows us to observe, in situ, the trajectory of a global religion, torn between its Jewish roots and universalistic ambitions. It emphasizes the importance, in this process, of the relationship it maintains, willingly or not, with its original religious frame. Consequently, the importance of local contexts is raised, illustrating the impact and combination of diverse factors. In addition to public and official responses to religious diversity, religious movements are affected by the religious landscape and the structures and authorities of religious organizations, as well as the religious and cultural characteristics of the population. Ultimately, this article underscores the complexity of the globalization of religion, which embraces a wide range of complex, sometimes ambiguous, situations lying between strong particularistic identity-claims and cosmopolitan, universalistic ambitions.

Los primeros pasos en el escorzo de la figura humana. "Un análisis desde la geometría"

A través de un recorrido histórico centrado en el Renacimiento, se exponen las aportaciones más significativas de teóricos y artistas en la evolución del escorzo de la figura humana desde un punto de vista geométrico. Los artistas que con sus dibujos y escritos ayudaban a otros en el aprendizaje de la representación, se apresuraron a incluir el estudio del escorzo en sus tratados, buscando métodos que facilitaran su dibujo sobre cualquier soporte y en cualquier posición en el espacio. En este artículo se analizan y enlazan los trazados propuestos por los estudiosos de la geometría, con las obras de arte que reflejan importantes avances en este sentido. Soportes como el lienzo, el muro o la bóveda, presentan al pintor superficies diferentes de trabajo y en distintas posiciones en el espacio. La figura humana, protagonista en la escena, tendrá que adaptarse a ellos para ser contemplada desde unos espacios arquitectónicos cada vez más amplios y con más posibilidades. Fue necesario dominar la perspectiva en la pintura, y muy particularmente en la mural, para ofrecer composiciones cada día más ambiciosas y sorprendentes.

Clinical significance of sperm DNA damage in assisted reproduction outcome

Background: Sperm DNA damage shows great promise as a biomarker of infertility. The study aim is to determine the usefulness of DNA fragmentation (DF), including modified bases (MB), to predict assisted reproduction treatment (ART) outcomes. Methods: DF in 360 couples (230 IVF and 130 ICSI) was measured by the alkaline Comet assay in semen and in sperm following density gradient centrifugation (DGC) and compared with fertilization rate (FR), embryo cumulative scores (ECS1) for the total number of embryos/treatment, embryos transferred (ECS2), clinical pregnancy (CP) and spontaneous pregnancy loss. MB were also measured using formamidopyrimidine DNA glycosylase to convert them into strand breaks. Results: In IVF, FR and ECS decreased as DF increased in both semen and DGC sperm, and couples who failed to achieve a CP had higher DF than successful couples (+12.2 semen, P = 0.004; +9.9 DGC sperm, P = 0.010). When MB were added to existing strand breaks, total DF was markedly higher (+17.1 semen, P = 0.009 and +13.8 DGC sperm, P = 0.045). DF was not associated with FR, ECS or CP in either semen or DGC sperm following ISCI. In contrast, by including MB, there was significantly more DNA damage (+16.8 semen, P = 0.008 and +15.5 DGC sperm, P = 0.024) in the group who did not achieve CP. Conclusion: SDF can predict ART outcome for IVF. Converting MB into further DNA strand breaks increased the test sensitivity, giving negative correlations between DF and CP for ICSI as well as IVF. © 2010 The Author.

Eclectic Dialectics: William Klein's Documentary Method

This article examines the relations between documentary aesthetics and the political sensibility of William Klein. Structured around the cultural phenomena that have remained integral to his career as a photographer and filmmaker - fashion, sport, and music - it discusses his enduring attachment to notions of freedom and creativity still associated with 1960s counter-culture, and the Vietnam War. In particular, it examines how how his films disrupt conventional categories, and subvert the familiar rhetoric of mainstream documentary film, especially that associated with cinéma vérité. A erstwhile protege of Dada, Klein has always valued the expressive potential of improbable juxtapositions, of intercutting between times and places, and subverting mainstream journalistic modes and intentions. The article argues that this attitude is increasingly rare among contemporary documentary filmmakers, and yet it is the very thing that gives his work a distinctive aesthetic texture, and relevance to any history of cinema.

A Frequency Domain Algorithm for Wave Separation

We propose a frequency domain adaptive algorithm for
wave separation in wind instruments. Forward and backward travelling waves are obtained from the signals acquired by two microphones placed along the tube, while the
separation ?lter is adapted from the information given by a
third microphone. Working in the frequency domain has a
series of advantages, among which are the ease of design of
the propagation ?lter and its differentiation with respect to
its parameters.
Although the adaptive algorithm was developed as a ?rst
step for the estimation of playing parameters in wind instruments it can also be used, without any modi?cations, for
other applications such as in-air direction of arrival (DOA)
estimation. Preliminary results on these applications will
also be presented.

Cement mantle fatigue failure in total hip replacement: Experimental and computational testing

One possible loosening mechanism of the femoral component in total hip replacement is fatigue cracking of the cement mantle. A computational method capable of simulating this process may therefore be a useful tool in the preclinical evaluation of prospective implants. In this study, we investigated the ability of a computational method to predict fatigue cracking in experimental models of the implanted femur construct. Experimental specimens were fabricated such that cement mantle visualisation was possible throughout the test. Two different implant surface finishes were considered: grit blasted and polished. Loading was applied to represent level gait for two million cycles. Computational (finite element) models were generated to the same geometry as the experimental specimens, with residual stress and porosity simulated in the cement mantle. Cement fatigue and creep were modelled over a simulated two million cycles. For the polished stem surface finish, the predicted fracture locations in the finite element models closely matched those on the experimental specimens, and the recorded stem displacements were also comparable. For the grit blasted stem surface finish, no cement mantle fractures were predicted by the computational method, which was again in agreement with the experimental results. It was concluded that the computational method was capable of predicting cement mantle fracture and subsequent stem displacement for the structure considered. (C) 2006 Elsevier Ltd.

Neutron diffraction, NMR and molecular dynamics study of glucose dissolved in the ionic liquid 1-ethyl-3-methylimidazolium acetate

beta-D-glucose dissolved in the ionic liquid 1-ethyl-3-methylimidazolium acetate in a 6 : 1 molar ratio (ionic liquid : glucose) has been studied by neutron scattering, NMR and molecular dynamics simulations. Good agreement was found between simulated neutron scattering profiles generated for isotopically substituted liquid systems and those experimentally determined as well as between simulated and experimental diffusion coefficients obtained by Pulsed Field Gradient NMR spectroscopy. The overriding glucose-ionic liquid interactions in the liquid are hydrogen-bonding between acetate oxygens and sugar hydroxyl groups. The ionic liquid cation was found to play only a minor role in the solvation of the sugar and does not participate in hydrogen-bonding with the sugar to any significant degree. NOESY experiments lend further evidence that there is no direct interaction between sugar hydroxyl groups and acidic hydrogens on the ionic liquid cation.

A critical appraisal of tools available for monitoring epigenetic changes in clinical samples from patients with myeloid malignancies

Research over the past decade has confirmed that epigenetic alterations act in concert with genetic lesions to deregulate gene expression in acute myeloid leukemia and myelodysplastic syndromes. In addition, we now have the capability to pharmaceutically target epigenetic modifications, and there is an urgent need forearly validation of the efficacy of the drugs. Also, an improved understanding of the functionality of epigenetic modifications may further pave the road towards an individualized therapy. Here, we provide the pros and cons of the currently most feasible methods used for characterizing the methylome in clinical samples, and give a brief introduction to novel approaches to sequencing that may revolutionize our abilities to characterize the genomes and epigenomes in acute myeloid leukemia and myelodysplastic syndrome patients.

The Rank of Queen's Counsel: Judicial Perspectives

The rank of queen's counsel, granted under the royal prerogative, has been part of the architecture of the legal profession and legal system since 1594 but has undergone many changes in that time, including most recently the adoption of new selection procedures. Recent cases in Northern Ireland have raised the question - what is the legal position of queen's counsel? By examining decided cases in context, this paper aims to explain judicial perspectives on what it means to be a QC.
