Polski Hamlet

Chapter is an attempt at reconstruction of the culminating moment of the first stage of the Polish reception of Shakespeare's "Hamlet". It has been entirely devoted to J. Słowacki's "Horsztyński". There is no doubt that "Horsztyński" should be viewed as the fullest and deepest interpretation of Shakespearean elements in the literary output of Juliusz Słowacki. Numerous citations and references to the works of the Elizabethan dramatist reach deeply into the structure of the world and human's life. Thanks to many adductions (citations) to Shakespeare, Słowacki approached the so much important problem for the Romantic period in Polish literature, namely the problem of individual tragedy of existence of the main character of a play and a clash with historical dilemmas of the community. The analysis of the text is aimed at showing all references to Shakespearean masterpiece with a particular emphasis on the hamletism of the charactwe of Szczęsny Kossakowski. The author describes the motif of betrayal, ever-present on different levels of the text structure, which in the most complete way describes the organisation of space between humans and their interaction in "Horsztyński". The author focuses his attention on detailed description and analysis of the recurrent themes frequently repeated in Szczęsny's statements, namely motifs of "man-harp", "man-actor in the theatre of the world", and "man-puppet", harlequin, clown. These motifs prove the sensibility of Szczęsny's to the theatrical aspect of the surrounding reality. The motif of darkness and of a blind man groping his way in the darkness so frequent in Szczęsny's statements can be interpreted as a manifestation of utter lack of hope and the feeling of uselessness of one's existence in the world.

Example-Based Image Restoration via Boosted Classifiers

We propose a novel image registration framework which uses classifiers trained from examples of aligned images to achieve registration. Our approach is designed to register images of medical data where the physical condition of the patient has changed significantly and image intensities are drastically different. We use two boosted classifiers for each degree of freedom of image transformation. These two classifiers can both identify when two images are correctly aligned and provide an efficient means of moving towards correct registration for misaligned images. The classifiers capture local alignment information using multi-pixel comparisons and can therefore achieve correct alignments where approaches like correlation and mutual-information which rely on only pixel-to-pixel comparisons fail. We test our approach using images from CT scans acquired in a study of acute respiratory distress syndrome. We show significant increase in registration accuracy in comparison to an approach using mutual information.

Bacterioviridins: novel sedimentary chlorins providing evidence for oxidative processes affecting palaeobacterial communities

Of novel sedimentary transformation products of bacteriochlorophyll a, 7,8-didehydro derivatives (Bacterioviridins), has been identified using high performance liquid chromatography with photodiode array detection and atmospheric pressure chemical ionisation liquid chromatography-multistage mass spectrometry. The derivatives occur in a range of sediments including Priest Pot (UK), les Salines de la Trinital, Ebre delta (Spain), Sutton-on-the-Forest (UK) and Certes (France). The Bacterioviridins are products of oxidative transformation of bacteriochlorophyll a, and their presence in sediments indicates exposure of the bacterial community to oxygen.

A novel sedimentary chlorin: structural evidence for a chlorophyll origin for aetioporphyrins

A novel sedimentary transformation product of chlorophyll, purpurin-7 phytyl ester, has been identified by atmo- spheric pressure chemical ionisation liquid chromatography mass-spectrometry in sediments from Lake Baikal, Russia, Loch Ness and Priest Pot, UK. This product of oxidative transformation is an intermediate on the transformation pathway leading to sedimentary aetioporphyrins and its occurrence lends strong support to the view that aetiopor- phyrins derive mainly from precursor chlorophylls.

El hombre metrosexual como Narciso contemporáneo: el papel del discurso publicitario actual en la construcción de la masculinidad

Existen diferentes definiciones del concepto de masculinidad. Por un lado están las normativas, que la entienden como lo que los hombres deberían ser y, por otro, los enfoques semióticos, que la definen como no-feminidad. Partiendo de este último enfoque y teniendo en cuenta que la feminidad ha evolucionado en los últimos años junto con la sociedad desdibujando la frontera entre lo que forma parte del rol femenino y lo que no, se puede afirmar que han surgido a partir de los renovados modelos de feminidad, diferentes y nuevas masculinidades entre las que se encuentra la del hombre metrosexual. Es en este tipo de masculinidad en concreto en la que se centra la presente investigación y en cómo se construye la narración de dicha masculinidad en el discurso publicitario actual recurriendo a la figura mítica de Narciso. Así, a partir de una revisión bibliográfica y de un análisis de contenido, se pretende analizar la influencia de la publicidad en la aparición del hombre metrosexual como nueva masculinidad en respuesta a la transformación de la feminidad, a la par que confirmar la presencia de la figura de Narciso como recurso en la construcción de la masculinidad en la publicidad actual.

Orientación al mercado y tipología de las cooperativas agroalimentarias en base a la competitividad. Caso-estudio de las citrícolas españolas

La globalización ha recrudecido más si cabe la competencia en los mercados y las empresas deben afianzar y mejorar su posición competitiva para asegurar la supervivencia. Para ello resulta vital, entre otras cuestiones, velar por los intereses de los inversores al tiempo que cuidan de sus clientes. Las cooperativas sufren una coyuntura semejante respecto a sus socios y el mercado, es decir respecto a sus clientes internos (socios) y externos (mercado). El enfoque de las actividades y la estrategia de la cooperativa frente a esta dualidad determina su grado de orientación al mercado.Los estudios relacionados con la orientación al mercado en cooperativas son escasos en comparación con otras formas empresariales y han estado normalmente centrados en la figura de las cooperativas de segundo grado y circunscritos a sectores muy específicos.El sector citrícola español es uno de los más dinámicos y desarrollados del panorama productivo agrario. Su extensa experiencia comercial tanto a nivel doméstico como internacional confiere un carácter diferenciador a las entidades que operan en este subsector. Este trabajo analiza la posición de las cooperativas citrícolas españolas en relación a la orientación al mercado así como los factores de gestión y estrategia que están relacionadoscon ella. Para ello se utiliza una escala MARKOR, validada en estudios anteriores, sobre una muestra de 45 cooperativas.Se establece además una tipología de cooperativas citrícolas en base a los factores de competitividad que permiten ahondar en el conocimiento que existe sobre esta cuestión en entidades de economía social. Los resultados ponen de manifiesto un elevado grado de relación entre la innovación, el perfil del empresario y el conocimiento del entorno en relación con el grado de orientación al mercado.

El artista contemporáneo ante la transformación de su obra. El paso del tiempo y su efecto sobre la significación de la materia

El paso del tiempo tiene una repercusión inevitable sobre las obras de arte. En el caso del arte contemporáneo muchos de los valores estéticos, culturales o sociales presentes en las mismas, están vinculados a la apariencia y al uso premeditado de la materia. La transformación de la materia tiene una repercusión sobre la intención y el discurso estético, por ello, y ante la imposibilidad de impedir el cambio, se hace necesaria una profunda reflexión sobre el concepto de autenticidad de la obra de arte y sobre el concepto de ruina prematura. Por otro lado, gracias a la figura del artista contemporáneo es posible documentar la producción actual para determinar si la mutación de la materia afectará a lo esencial en las obras. En este sentido, el trabajo ha conseguido concretar, para el caso de varios artistas fundamentales del panorama español, qué aspectos deben, por ser esenciales, permanecer inmutables con el paso del tiempo.

Gene expression profiling in MDS and AML: potential and future avenues

Today, the classification systems for myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) already incorporate cytogenetic and molecular genetic aberrations in an attempt to better reflect disease biology. However, in many MDS/AML patients no genetic aberrations have been identified yet, and even within some cytogenetically well-defined subclasses there is considerable clinical heterogeneity. Recent advances in genomics technologies such as gene expression profiling (GEP) provide powerful tools to further characterize myeloid malignancies at the molecular level, with the goal to refine the MDS/AML classification system, incorporating as yet unknown molecular genetic and epigenetic pathomechanisms, which are likely reflected by aberrant gene expression patterns. In this study, we provide a comprehensive review on how GEP has contributed to a refined molecular taxonomy of MDS and AML with regard to diagnosis, prediction of clinical outcome, discovery of novel subclasses and identification of novel therapeutic targets and novel drugs. As many challenges remain ahead, we discuss the pitfalls of this technology and its potential including future integrative studies with other genomics technologies, which will continue to improve our understanding of malignant transformation in myeloid malignancies and thereby contribute to individualized risk-adapted treatment strategies for MDS and AML patients.

Inclusive development? State-led land development model in New Town, Kolkata

Urban land development in India is changing under the auspices of economic liberalisation. Kolkata has been in the forefront of this transformation through development of new townships in the urban peripheries based on a distinctive state-led land development model. Within this context New Town, Kolkata (also known as Rajarhat) provides a highly illuminative case to articulate the ways in which the state is implementing its neoliberal agenda in land development. It rides on political and ideological high ground by seeking to create a ‘model development’ of state–market partnership for dual goals of fostering capitalist interest while fulfilling welfarist principles. Interesting insights have emerged that point to a policy paradox. On one hand, the process follows market principles of efficacy and efficiency; on the other hand, state’s keenness to extend control persists, thereby creating a highly uneven terrain for state–market interaction. New Town reflects a typical quasi-market condition shaped by the monopolistic state, the poorly structured role of the private sector, an absence of civic bodies, and minimal land and housing provision for the poor. In India, as internationally, the economic liberalisation market ideology is increasingly construed as good governance. In this context New Town is a step in the right direction, but the progress is patchy, uneven, and still evolving.

An Escherichia coli undecaprenyl-pyrophosphate phosphatase implicated in undecaprenyl phosphate recycling

Undecaprenyl phosphate (Und-P) is a universal lipid carrier of glycan biosynthetic intermediates for carbohydrate polymers that are exported to the bacterial cell envelope. Und-P arises from the dephosphorylation of undecaprenyl pyrophosphate (Und-PP) molecules produced by de novo synthesis and also from the recycling of released Und-PP after the transfer of the glycan component to other acceptor molecules. The latter reactions take place at the periplasmic side of the plasma membrane, while cytoplasmic enzymes catalyse the de novo synthesis. Four Und-PP pyrophosphatases were recently identified in Escherichia coli. One of these, UppP (formerly BacA), accounts for 75 % of the total cellular Und-PP pyrophosphatase activity and has been suggested to participate in the Und-P de novo synthesis pathway. Unlike UppP, the other three pyrophosphatases (YbjG, YeiU and PgpB) have a typical acid phosphatase motif also found in eukaryotic dolichyl-pyrophosphate-recycling pyrophosphatases. This study shows that double and triple deletion mutants in the genes uppP and ybjG, and uppP, ybjG and yeiU, respectively, are supersensitive to the Und-P de novo biosynthesis inhibitor fosmidomycin. In contrast, single or combined deletions including pgpB have no effect on fosmidomycin supersensitivity. Experimental evidence is also presented that the acid phosphatase motifs of YbjG and YeiU face the periplasmic space. Furthermore, the quadruple deletion mutant DeltauppP-DeltaybjG-DeltayeiU-DeltawaaL has a growth defect and abnormal cell morphology, suggesting that accumulation of unprocessed Und-PP-linked O antigen polysaccharides is toxic for these cells. Together, the results support the notion that YbjG, and to a lesser extent YeiU, exert their enzymic activity on the periplasmic side of the plasma membrane and are implicated in the recycling of periplasmic Und-PP molecules.

Merula

Merula is a thirty-minute work for bass flute and electronics, commissioned by Icelandic flautist Kolbeinn Bjarnason. The premiere took place in the Belfast Festival at Queen’s in November 2012. A recording will be made in 2014. Further performances in Iceland, Norway and Poland are anticipated in 2014-15. I have given a research seminar on this work at Queen’s and will deliver it again at the University of Oxford during 2013-14.

Research Goals
1) To develop an effective means of notating live electronics in a manner that would sustain the work's performance history beyond the current generation of software
2) To apply the techniques of transcription and spectralism used in my composition, Perseid, using birdsongs as source material
3) To explore the problem of sustaining large-scale form in music that is primarily fast
4) To facilitate the emergence of the solo bass flute as an important solo instrument through the completion of a new large-scale work

Methodology
• Methodologies employed in this project included sound recording, sound analysis and transcription, extensive precompositional sketching, electroacoustic techniques of sound manipulation, designing complex live processes of sound transformation and spatialisation
• A considerable part of this work was collaboration with the flautist, both in SARC and Iceland. Mr. Bjarnason was involved all stages of the work, frequently recording source materials and helping to ensure the idiomatic nature of the flute writing.
• Developing a means of notating the live electronics. Building on a model suggested by Pierre Boulez in Anthemes 2 (1998), the score of this work includes a technical manual that describes electronic processes in a manner that can be reprogrammed in subsequent generations of software. Combined with a system of notations employed in the full score, the technical manual will enable this composition to be performed by a wide range of performers and technical teams, with appropriately identical results.

Northern Ireland: 20 Years After the Cease-Fires

In the closing months of 1994, the principal paramilitary organizations in Northern Ireland declared that their campaigns of violence were at an end. The cease-fires called by republican and loyalist groupings represented the most significant heralds of a complex process of conflict transformation that continues to unfold even twenty years on. In this introduction, we set out to map the key developments that have shaped the tortuous narrative of the Northern Irish 'peace process', thereby providing the historical backdrop for the articles that follow. While remarkable progress has been made over the two decades since the paramilitary cease-fires, the political context and future of the region remain rather more fraught than is often assumed abroad. It is perhaps best, then, to speak of the six counties in terms not of resolution but rather of ambiguity. Twenty years on from the optimism that greeted the paramilitary cease-fires, Northern Ireland retains the essential 'inbetweenness' of a political space that has moved from a 'long war' through a 'long peace' and into a profoundly undecided future. © 2014 Taylor & Francis Group, LLC.
