La Rebelión de Los Esclavos: Tragedia y posibilidad en el teatro de Raúl Hernández Garrido
Get PDFThesis advisor: Irene MizrahiThis study is an analysis of the theatre of the Spanish contemporary playwright Raúl Hernández Garrido. It explores in depth his tragedy Los engranajes and it applies (in a more referential manner) the results of this investigation to the rest of his plays: Los malditos, Los restos: Agamenón vuelve a casa and Los restos Fedra, included in the cycle Los esclavos. The author utilizes myth and greek tragedy intentionally in order to make readers reflect upon the concepts of destiny and the fragility of human action as well as the fragmentation, hopelessness and dissatisfaction of contemporary societies. My study demonstrates that the formal innovation of these plays and the use of tragedy as their argumental framework present not only a criticism about these concepts but also an approach towards change and a social ethic of hope founded in creative freedom and the cooperation between the text and all people involved in the creative process. As a theoretical frame of reference for my study I use texts from Sigmund Freud, Jacques Lacan, Friedrich Nietzsche, René Girard and Emmanuel Levinas. Their reflections about the genre of tragedy and/or the concept of the tragic shed light upon my analysis of themes such as human suffering, trauma, the abuse of power, violence and the ethics of responsibility in the works of our author.Thesis (PhD) — Boston College, 2011.Submitted to: Boston College.

The fantastic in Spain during the late- nineteenth and early-twentieth centuries
Get PDFThis thesis has as its primary objective the drawing together and subsequent theorisation of diverse texts which can be understood to be examples of Spanish fantastic literature. It demonstrates that from nineteenth-century Realism and Naturalism (exemplified in narratives by Pérez Galdós, Alarcón and Pardo Bazán), through turn-of-the-century modernismo (Valle-Inclán and Zamacois) to twentieth- century proto-existentialism (Unamuno), a significant number of texts were produced which, in spite of the obvious differences between them, refute the widely held idea that 'the fantastic' and Spanish literature share little common ground. The thesis is therefore one more step along the journey of establishing that Spanish fantastic literature is as important and integral to the whole swathe of Spanish cultural production as it is in many other European countries. The critical analyses of the narratives push at the boundaries of previous interpretative strategies both in terms of the fantastic and of the texts themselves. The exception to this interrogation and reinvigoration of earlier interpretations is to be found in the approach to the narratives by Zamacois, which have hitherto received very little critical attention. These detailed readings draw out the complexities and intriguing perspectives which the fantastic in Spain presents to the attentive reader. By means of these textual analyses, the thesis also explores some of the various possibilities presented by the fantastic itself, putting flesh on the theoretical bones of several different critical discourses. Ultimately, this thesis charts a dynamic and coherent corpus of material which represents the process of the psychologisation of the supernatural from Romanticism onwards. Each successive text more starkly expresses the unreal horrors of the fractured human mind, as well as the mutations of the body. As such, the evolutionary history of the fantastic in Spain is shown to be more gripping and relevant than has hitherto been understood to be the case
The developmental cell biology of Trypanosoma brucei
Get PDFTrypanosoma brucei provides an excellent system for studies of many aspects of cell biology, including cell structure and morphology, organelle positioning, cell division and protein trafficking. However, the trypanosome has a complex life cycle in which it must adapt either to the mammalian bloodstream or to different compartments within the tsetse fly. These differentiation events require stage-specific changes to basic cell biological processes and reflect responses to environmental stimuli and programmed differentiation events that must occur within a single cell. The organization of cell structure is fundamental to the trypanosome throughout its life cycle. Modulations of the overall cell morphology and positioning of the specialized mitochondrial genome, flagellum and associated basal body provide the classical descriptions of the different life cycle stages of the parasite. The dependency relationships that govern these morphological changes are now beginning to be understood and their molecular basis identified. The overall picture emerging is of a highly organized cell in which the rules established for cell division and morphogenesis in organisms such as yeast and mammalian cells do not necessarily apply. Therefore, understanding the developmental cell biology of the African trypanosome is providing insight into both fundamentally conserved and fundamentally different aspects of the organization of the eukaryotic cell
Assessment of avocado textural changes during ripening by using contactless air-coupled ultrasound
Get PDF[EN] In the present study, the use of the air-coupled ultrasonic technique has been analysed as a new tool for the contactless assessment of the avocado post-harvest textural modifications during ripening. Thus, ultrasonic parameters, such as maximum wave amplitude and ultrasound velocity, and textural ones, such as hardness, elastic modulus and relaxation capacity, were measured on avocado slices. During ripening, avocado reduced its elastic modulus (from 2.29 +/- 0.75 to 0.16 +/- 0.08 MPa), became softer and became more viscoelastic, which was well described from zero and first-order kinetic models. These changes increased ultrasound attenuation, decreasing the maximum amplitude of the ultrasonic signal (from 336.6 to 55.4 V/m), while the ultrasonic velocity remained constant, between 320.1 +/- 6.9 and 316.4 +/- 82.6 m/s. Thereby, the maximum ultrasonic amplitude, which adequately correlated with textural parameters (r(avg) = 0.85), could be used to assess the post-harvest ripening on avocado slices.The authors acknowledge the financial support from the Ministerio de Economia y Competitividad (MINECO) and Agencia Estatal de InvestigaciOn in Spain (Project RTC-2017-6314-2) and the Generalitat Valenciana.

For this purpose, daily data of futures and spot exchange rates of three major international currencies, Euro, British pound and Japanese yen, against the American dollar, are used to analyze hedge ratios and hedging effectiveness resulting from using
two different maturity currency contracts, near-month and next-to-near-month contract. Following Chang et al. [17], we estimate four multivariate volatility models (namely CCC, VARMA-AGARCH, DCC and BEKK), and calculate optimal portfolio weights
and optimal hedge ratios to identify appropriate currency hedging strategies. The hedging effectiveness index suggests that the best results in terms of reducing the variance of the portfolio are for the USD/GBP exchange rate. The empirical results
show that futures hedging strategies are slightly more effective when the near-month future contract is used for the USD/GBP and USD/JPY currencies. Moreover, the CCC and AGARCH models provide similar hedging effectiveness, which suggests that
dynamic asymmetry may not be crucial empirically, although some differences appear when the DCC and BEKK models are used.Fac. de Ciencias Económicas y EmpresarialesInstituto Complutense de Análisis Económico (ICAE)TRUEpu
User involvement in a Cochrane systematic review: using structured methods to enhance the clinical relevance, usefulness and usability of a systematic review update
Get PDFBackground: This paper describes the structured methods used to involve patients, carers and health professionals in an update of a Cochrane systematic review relating to physiotherapy after stroke and explores the perceived impact of involvement.Methods: We sought funding and ethical approval for our user involvement. We recruited a stakeholder group comprising stroke survivors, carers, physiotherapists and educators and held three pre-planned meetings during the course of updating a Cochrane systematic review. Within these meetings, we used formal group consensus methods, based on nominal group techniques, to reach consensus decisions on key issues relating to the structure and methods of the review.Results: The stakeholder group comprised 13 people, including stroke survivors, carers and physiotherapists with a range of different experience, and either 12 or 13 participated in each meeting. At meeting 1, there was consensus that methods of categorising interventions that were used in the original Cochrane review were no longer appropriate or clinically relevant (11/13 participants disagreed or strongly disagreed with previous categories) and that international trials (which had not fitted into the original method of categorisation) ought to be included within the review (12/12 participants agreed or strongly agreed these should be included). At meeting 2, the group members reached consensus over 27 clearly defined treatment components, which were to be used to categorise interventions within the review (12/12 agreed or strongly agreed), and at meeting 3, they agreed on the key messages emerging from the completed review. All participants strongly agreed that the views of the group impacted on the review update, that the review benefited from the involvement of the stakeholder group, and that they believed other Cochrane reviews would benefit from the involvement of similar stakeholder groups.Conclusions: We involved a stakeholder group in the update of a Cochrane systematic review, using clearly described structured methods to reach consensus decisions. The involvement of stakeholders impacted substantially on the review, with the inclusion of international studies, and changes to classification of treatments, comparisons and subgroup comparisons explored within the meta-analysis. We argue that the structured approach which we adopted has implications for other systematic reviews.</p

DESI will determine precise redshifts and employ the baryon acoustic oscillation method to measure distances from the nearby universe to beyond redshift z > 3.5, and employ redshift space distortions to measure the growth of structure and probe potential modifications to general relativity. We describe the significant instrumentation we developed to conduct the DESI survey. This includes: a wide-field, 3fdg2 diameter prime-focus corrector; a focal plane system with 5020 fiber positioners on the 0.812 m diameter, aspheric focal surface; 10 continuous, high-efficiency fiber cable bundles that connect the focal plane to the spectrographs; and 10 identical spectrographs. Each spectrograph employs a pair of dichroics to split the light into three channels that together record the light from 360–980 nm with a spectral resolution that ranges from 2000–5000. We describe the science requirements, their connection to the technical requirements, the management of the project, and interfaces between subsystems. DESI was installed at the 4 m Mayall Telescope at Kitt Peak National Observatory and has achieved all of its performance goals. Some performance highlights include an rms positioner accuracy of better than 0farcs1 and a median signal-to-noise ratio of 7 of the [O ii] doublet at 8 × 10−17 erg s−1 cm−2 in 1000 s for galaxies at z = 1.4–1.6. We conclude with additional highlights from the on-sky validation and commissioning, key successes, and lessons learned. © 2022. The Author(s).
