Crossing the threshold: exile and literature in "El Canto del peregrino" (1999) by Angelina Muñiz-Huberman

This paper analyses the relation between exile and literature in Angelina Muñiz-Huberman’s work El canto del peregrino. In this collection of essays, the Spanish-Mexican writer, member of the second generation of Spanish Republican exiles in Mexico, outlines a poetics of exile. From the outset, the relation between exile and literature is presented in terms of identity: while defining exile as “literary form”, the book tends to prefer a metaphorical concept of exile over ‘merely’ historical or referential approaches to it. More in particular, this paper will examine how the author constructs an identity of ‘exiled writer’ based on the close association between exile and literature on the one hand, and on the view of exile as ‘home’ or ‘dwelling’, on the other hand. A second point of interest concerns the discursive impact of this literary and metaphorical concept of exile and the author’s personal experience. A brief analysis of the essayist’s discursive voice and her writing practice shows how Muñiz-Huberman gives shape to an intrinsically complex and paradoxical view on exile.

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.

'Ulster's policing goes global': The police reform process in Northern Ireland and the creation of a global brand

This paper engages with contemporary discussions in relation to the commodification of policing and security. It suggests that the existing literature regarding these trends has been geared primarily towards commercial security providers and has failed to address the processes by which public policing models are commodified and marketed both within, and through, the transnational policing community. Drawing upon evidence from the police change process in Northern Ireland, we argue that a Northern Irish Policing Model (NIPM) has emerged in the aftermath of the Independent Commission on Policing (ICP) reforms. This is increasingly branded and promoted on the global stage. Furthermore, we suggest that the NIPM is not monolithic, but segmented, and targeted towards a number of different 'consumers' both domestically and transnationally. Reflecting these diverse markets, the NIPM draws upon two seemingly incongruous constituent elements: the 'best practice' lessons of policing transition, as embodied in the ICP reforms; and, the legacy of counter-terrorism expertise drawn from the preceding decades of conflict. The discussion concludes by querying as to which of these components of the NIPM is in the ascendancy.

Surface plasmons in layered structures with semiconductor and metallic films

The complete spectrum of eigenwaves including surface plasmon polaritons (SPP), dynamic (bulk) and complex waves in the layered structures containing semiconductor and metallic films has been explored. The effects of loss, geometry and the parameters of dielectric layers on the eigenmode spectrum and, particularly, on the SPP modes have been analysed using both the asymptotic and rigorous numerical solutions of the full-wave dispersion equation. The field and Poynting vector distributions have been examined to identify the modes and elucidate their properties. It has been shown that losses and dispersion of permittivity qualitatively alter the spectral content and the eigenwave properties. The SPP counter-directional power fluxes in the film and surrounding dielectrics have been attributed to vortices of power flow, which are responsible for the distinctive features of SPP modes. It has been demonstrated for the first time that the maximal attainable slow-wave factor of the SPP modes guided by thin Au films at optical frequencies is capped not by losses but the frequency dispersion of the actual Au permittivity. © 2009 EDP Sciences.

Coherent X-ray production via pulse reflection from laser-driven dense electron sheets

A scheme to obtain brilliant x-ray sources by coherent reflection of a counter-propagating pulse from laser-driven dense electron sheets is theoretically and numerically investigated in a self-consistent manner. A radiation pressure acceleration model for the dynamics of the electron sheets blown out from laser-irradiated ultrathin foils is developed and verified by PIC simulations. The first multidimensional and integral demonstration of the scheme by 2D PIC simulations is presented. It is found that the reflected pulse undergoes Doppler-upshift by a factor 4?z2, where ?z = (1- vz2/c2)-1/2 is the effective Lorentz factor of the electron sheet al ong its normal direction. Meanwhile the pulse electric field is intensified by a factor depending on the electron density of the sheet in its moving frame ne/?, where ? is the full Lorentz factor.

Laser pulse compression and amplification via Raman backscattering in plasma

A simple theoretical model is proposed for the interaction between two counter-propagating laser pulses (a pump and a seed pulse) in unmagnetized plasma. Pulse compression and amplification are observed via numerical simulation. A one dimensional fluid model for stimulated Raman backscattering is proposed to investigate the pulse compression and pulse amplification mechanisms. To accomplish this, energy is transferred from the long pump pulse to a seed pulse, with a Langmuir plasma wave mediating the transfer. The study focuses on the intensity profile of the pump laser pulse. A Gaussian and a ring intensity profile are, separately, considered for the pump laser pulse.

Can Civil Society Succeed Where Elites Have Failed in the War on Sectarianism? Towards an infinitely demanding politics for the North

Caught between the well-armed imaginations of paramilitary organisations competing for the hearts and minds of a divided population, and state engineering of a liberal peace, civil society's impact on Northern Ireland's identity politics was limited during the thirty-year conflict. Specifically, the community and voluntary sector itself has tended to replicate as much as it challenged patterns of segregation in many of its own structures. With plans set out in the Northern Ireland Executive's Programme for Government (2008-11) to engage civil society in opening a new era of ‘good relations’ work to counter sectarianism and racism, civil society organisations will face a complex terrain, facing scepticism about their contribution to peace-making before the Good Friday Agreement, and working in a post-Agreement environment marked by continuing elite and communal antagonism demonstrated by the crisis at the turn of 2009 over devolution of justice and policing powers to the Northern Ireland Executive. A significant aspect of the resolution was a belated agreement by Sinn Fein and the DUP on a new community relation strategy, Cohesion, Sharing and Integration. This article suggests that civil society has a significant role to play in encouraging communities to confront the contradictions and tensions that continue to haunt the political architects of the Good Friday Agreement by affirming a radical and contingent vision of democracy as democratisation at a distance from the identity-saturated politics of the state-region of Northern Ireland. It draws on the work of Simon Critchley, Emmanuel Levinas and Wendy Brown, to offer an approach to identity politics in post-conflict Northern Ireland, focusing on the future orientation of civil society.

Electronic cell counting to measure total cell numbers in bronchoalveolar lavage fluid

Cell counting of bronchoalveolar lavage (BAL) fluid is performed manually in routine practice. This has both methodological and inherent errors; however, the accuracy and suitability of automated counting devices have been questioned. In this study, a Coulter(R) Counter D Industrial model was calibrated and then used to measure the total cell count in unprocessed bronchoalveolar lavage fluid, and compared to a standard manual method.

Adrenomedullin Gene Delivery is Cardio-protective in a Model of Chronic Nitric Oxide Deficiency Combining Pressure Overload, Oxidative Stress and Cardiomyocyte Hypertrophy

BACKGROUND/AIMS:
Chronic inhibition of nitric oxide (NO) synthesis is associated with hypertension, myocardial ischemia, oxidative stress and hypertrophy; expression of the vasodilator peptide, adrenomedullin (AM) and its receptors is augmented in cardiomyocytes, indicating that the myocardial AM system may be activated in response to pressure loading and ischemic insult to serve a counter-regulatory, cardio-protective role. The study examined the hypothesis that oxidative stress and hypertrophic remodeling in NO-deficient cardiomyocytes are attenuated by adenoviral vector-mediated delivery of the human adrenomedullin (hAM) gene in vivo.

METHODS:
The NO synthesis inhibitor, N(G)-nitro-L-arginine methyl ester (L-NAME, 15mg . kg(-1) . day(-1)) was given to rats for 4 weeks following systemic administration via the tail vein of a single injection of either adenovirus harbouring hAM cDNA under the control of the cytomegalovirus promoter-enhancer (Ad.CMV-hAM-4F2), or for comparison, adenovirus alone (Ad.Null) or saline. Cardiomyocytes were subsequently isolated for assessment of the influence of each intervention on parameters of oxidative stress and hypertrophic remodelling.

RESULTS: Cardiomyocyte expression of the transgene persisted for > or =4 weeks following systemic administration of adenoviral vector. In L-NAME treated rats, relative to Ad.Null or saline administration, Ad.CMV-hAM-4F2 (i) reduced augmented cardiomyocyte membrane protein oxidation and mRNA expression of pro-oxidant (p22phox) and anti-oxidant (SOD-3, GPx) genes; (ii) attenuated increased cardiomyocyte width and mRNA expression of hypertrophic (sk-alpha-actin) and cardio-endocrine (ANP) genes; (iii) did not attenuate hypertension.

CONCLUSIONS: Adenoviral vector mediated delivery of hAM resulted in attenuation of myocardial oxidative stress and hypertrophic remodelling in the absence of blood pressure reduction in this model of chronic NO-deficiency. These findings are consistent with a direct cardio-protective action in the myocardium of locally-derived hAM which is not dependant on NO generation.

Children’s Burial Grounds in Ireland (Cilliní) and Parental Emotions Toward Infant Death

Cilliní—or children’s burial grounds—were the designated resting places for unbaptized infants and other members of Irish society who were considered unsuitable by the Roman Catholic Church for burial in consecrated ground. The sites appear to have proliferated from the seventeenth century onwards in the wake of the Counter-Reformation. While a number of previous studies have attempted to relate their apparently marginal characteristics to the liminality of Limbo, evidence drawn from the archaeological record and oral history accounts suggests that it was only the Roman Catholic Church that considered cilliní, and those interred within, to be marginal. In contrast, the evidence suggests that the families of the dead regarded the cemeteries as important places of burial and treated them in a similar manner to consecrated burial grounds.

Early crime writing and the state: Jonathan Wild, Daniel Defoe and Bernard Mandeville in 1720s London

This article argues that the early development of crime writing needs to be understood in relation to the consolidation of the modern state. It demonstrates that London in the 1720s constitutes a significant moment in this early development for three main reasons. First, the period witnessed a crime epidemic which reached its climax in the 1720s and which precipitated a set of particularly aggressive counter-measures by the state; second, it saw the rise and eventual fall of the infamous Jonathan Wild who acted as both thief and surrogate policeman; and third, it was also marked by a surge in interests on the part of writers like Daniel Defoe and Bernard Mandeville in the related matters of crime and punishment. This article explores the ways in which accounts of crime and punishment in this period deployed and in some instances interrogated the rhetoric of social contract theory and writings on statecraft, particularly by Thomas Hobbes and Mandeville. But while the criminal biographies and gallows sermons produced by the Newgate prison’s ‘ordinaries’ provided crude and reductive accounts of the efficacy of the state, the article shows how two accounts of the life of Jonathan Wild (by Defoe and H.D) responded in highly complex ways to the issues of crime and policing and provided a consistently and self-consciously ambivalent reading of the state and state power. To conclude, I suggest that this ambivalence can be read as a critique of the impartial or neutral state and that it constitutes one of the key features of what we would later understand to be crime writing as a dedicated literary genre.

Photo-double detachment from the F- ion

The correlated process of photodetaching two electrons from the F- ion following the absorption of a single photon has been investigated over an energy range 20-62 eV. In the experiment, a beam of photons from the Advanced Light Source was collinearly merged with a counter-propagating beam of F- ions from a sputter ion source. The F+ ions produced in the interaction region were detected, and the normalized signal was used to monitor the relative cross section for the double-detachment reaction. An absolute scale for the cross section was established by measuring the spatial overlap of the two beams and by determining the efficiency for collection and detection of the F+ ions. The measured cross section is compared with R-matrix and random phase approximation calculations. These calculations show that the Auger decay of the 2s2p(6) core-excited state of the F atom plays a minor role in the production of F+ ions and that double detachment is likely to be dominated by simultaneous correlated ejection of two valence electrons at energies well above threshold.

Struell Wells: pagan past and Christian present

The complex of buildings at Struell Wells, near Downpatrick, Co. Down, is the most extensive at a holy well in Ireland. It comprises two wells, two bath-houses and the ruins of a church. Nearby is a natural rock feature known as St Patrick’s Chair. The earliest reference to the wells is likely to be in the 8th century Fíacc’s Hymn which records the site being visited by St Patrick. The earliest reference to their healing powers can be dated to the 11th/12th century and the site continued to be a focus of pilgrimage at midsummer until its suppression in the nineteenth century. The site seems to be unique in that bathing in the wells constituted an integral part of the rituals performed by pilgrims. A recent study of the holy well phenomenon in Ireland has suggested that the rituals associated with them have their origins in the Counter-Reformation (Carroll 1999). The evidence from Struell, however, strongly suggests that it was an important sacred site in pre-Christian times.

Regarding the Real: Cinema, Documentary, and the Visual Arts

Regarding the Real: Cinema, Documentary, and the Visual Arts develops an interdisciplinary approach to documentary film, focusing on its cultural and formal relations to other visual arts, such as animation, assemblage, photography, painting, sculpture, and architecture. The book considers the work of figures whose preferred film language is associative and fragmentary, and for whom the documentary is an endlessly open form, an unstable expressive phenomenon that cannot but interrogate the validity of its own narratives and representational modes. Combining close analysis with cultural history, Regarding the Real calls for a re-assessment of the influence of the modern arts in subverting the structures of realism typically associated with documentary filmmaking.

Evidence for progressive Holocene aridification in southern Africa recorded in Namibian hyrax middens: Implications for African Monsoon dynamics and the

Presented here are stable nitrogen isotope data from a rock hyrax (Procavia capensis) middens from northwestern Namibia that record a series of rapid aridification events beginning at ca. 3800 cal yr BP, and which mark a progressive decrease in regional humidity across the Holocene. Strong correlations exist between this record and other terrestrial and marine archives from southern Africa, indicating that the observed pattern of climate change is regionally coherent. Combined, these data indicate hemispheric synchrony in tropical African climate change during the Holocene, with similar trends characterising the termination of the 'African Humid Period' (AHP) in both the northern and southern tropics. These findings run counter to the widely accepted model of direct low-latitude insolation forcing, which requires an antiphase relationship to exist between the hemispheres. The combined dataset highlights: 1) the importance of forcing mechanisms influencing the high northern latitudes in effecting low-latitude climate change in Africa, and 2) the potential importance of solar forcing and variations in the Earth's geomagnetic shield in determining both long-term and rapid centennial-scale climate changes, identifying a possible mechanism for the variations marking the AHP termination in both the southern and northern tropics.
