X-ray and extreme-ultraviolet emission from the coronae of Capella

The primary objective of this work is the analysis and interpretation of coronal observations of Capella obtained in 1999 September with the High Energy Transmission Grating Spectrometer on the Chandra X-ray Observatory and the Extreme Ultraviolet Explorer (EUVE). He-like lines of O (O vii) are used to derive a density of 1.7 x 10(10) cm(-3) for the coronae of the binary, consistent with the upper limits derived from Fe xxi, Ne ix and Mg xi line ratios. Previous estimates of the electron density based on Fe xxi should be considered as upper limits. We construct emission measure distributions and compare the theoretical and observed spectra to conclude that the coronal material has a temperature distribution that peaks around 4-6 MK, implying that the coronae of Capella were significantly cooler than in the previous years. In addition, we present an extended line list with over 100 features in the 5-24 Angstrom wavelength range, and find that the X-ray spectrum is very similar to that of a solar flare observed with SMM. The observed to theoretical Fe xvii 15.012-Angstrom line intensity reveals that opacity has no significant effect on the line flux. We derive an upper limit to the optical depth, which we combine with the electron density to derive an upper limit of 3000 km for the size of the Fe xvii emitting region. In the same context, we use the Si iv transition region lines of Capella from HST/Goddard High-Resolution Spectrometer observations to show that opacity can be significant at T = 10(5) K, and derive a path-length of approximate to 75 kin for the transition region. Both the coronal and transition region observations are consistent with very small emitting regions, which could be explained by small loops over the stellar surfaces.

Multi-zone TAP-reactors theory and application - IV. Ideal and non-ideal boundary conditions

We study the influence of non-ideal boundary and initial conditions (BIC) of a temporal analysis of products (TAP) reactor model on the data (observed exit flux) analysis. The general theory of multi-response state-defining experiments for a multi-zone TAP reactor is extended and applied to model several alternative boundary and initial conditions proposed in the literature. The method used is based on the Laplace transform and the transfer matrix formalism for multi-response experiments. Two non-idealities are studied: (1) the inlet pulse not being narrow enough (gas pulse not entering the reactor in Dirac delta function shape) and (2) the outlet non-ideality due to imperfect vacuum. The effect of these non-idealities is analyzed to the first and second order of approximation. The corresponding corrections were obtained and discussed in detail. It was found that they are negligible. Therefore, the model with ideal boundary conditions is proven to be completely adequate to the description and interpretation of transport-reaction data obtained with TAP-2 reactors.

Coordination and movement pathology: models of structure and function

Here we consider the role of abstract models in advancing our understanding of movement pathology. Models of movement coordination and control provide the frameworks necessary for the design and interpretation of studies of acquired and developmental disorders. These models do not however provide the resolution necessary to reveal the nature of the functional impairments that characterise specific movement pathologies. In addition, they do not provide a mapping between the structural bases of various pathologies and the associated disorders of movement. Current and prospective approaches to the study and treatment of movement disorders are discussed. It is argued that the appreciation of structure-function relationships, to which these approaches give rise, represents a challenge to current models of interlimb coordination, and a stimulus for their continued development.

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.

Rarity, pseudodiagnosticity and Bayesian reasoning

Three experiments investigated the effect of rarity on people's selection and interpretation of data in a variant of the pseudodiagnosticity task. For familiar (Experiment 1) but not for arbitrary (Experiment 3) materials, participants were more likely to select evidence so as to complete a likelihood ratio when the initial evidence they received was a single likelihood concerning a rare feature. This rarity effect with familiar materials was replicated in Experiment 2 where it was shown that participants were relatively insensitive to explicit manipulations of the likely diagnosticity of rare evidence. In contrast to the effects for data selection, there was an effect of rarity on confidence ratings after receipt of a single likelihood for arbitrary but not for familiar materials. It is suggested that selecting diagnostic evidence necessitates explicit consideration of the alternative hypothesis and that consideration of the possible consequences of the evidence for the alternative weakens the rarity effect in confidence ratings. Paradoxically, although rarity effects in evidence selection and confidence ratings are in the spirit of Bayesian reasoning, the effect on confidence ratings appears to rely on participants thinking less about the alternative hypothesis.

The effect of statistics anxiety on students’ predicted and actual test scores

This study investigated the effect of statistics anxiety and attitudes on first year psychology students’ predicted and actual statistics class test scores. A total of 52 students completed the Statistics Anxiety Rating Scale and estimated their class test scores one week before their test at the end of first year. Regression models were conducted with the six attitude and anxiety subscales as predictors and the predicted and actual test scores as criterion variables. The results showed that computation self concept and fear of asking for help accounted for 37% of the variance in predicted test scores. However, when actual test scores were analysed the significant predictors were worth of statistics and interpretation anxiety, which accounted for 20% of the variance. These results suggested that while statistics anxiety does influence students’ perceptions of their competence it appears to have less effect on their actual performance. Results also suggested that students were unaware of their own statistical competence. Remedial action is required to address the level of statistics anxiety experienced by first year undergraduate psychology students, as it appears to result in unrealistic assessments of their ability and has detrimental effects on their statistics self-efficacy.

Beckett and Performance

The recent interest in genealogical criticism in Beckett Studies, fuelled by the reading notes that Beckett compiled in the 1920’s and 1930’s, has led to a particular focus on Beckett’s formative years, and on the intersections between his work, especially the novels and early criticism, and his intellectual reading. While this has produced much valuable and fascinating matrial, perhaps it is time to return to the works themselves, and especially, to the theatre. Having just published a book on Performing Embodiment in Samuel Beckett’s Drama (London, Routledge, 2010), I would like to develop further the area of presence and performance in Beckett’s theatre. Performance studies and phenomenology have offered new ways of approaching the ontology of performance in Beckett’s theatre, and I intend to analyze this, with particular reference to specific productions of Beckett’s plays. Firstly, I want to look at some of Beckett’s own comments about particular performances / productions (for example in the Barbara Bray correspondence, Trinity College Dublin), and, secondly, to analyze from the perspective / experience of an audience member a number of performances by (mainly Anglophone) ‘Beckett actors’, including Billie Whitelaw and David Warrilow. Drawing on recent discussions of presence and performance (Jane Goodall, Cormac Power), I will offer some reflections on the complexity of presence (of persona and performer, of body and voice) and its haunting power in performances of Beckett’s drama.

Data-driven optimal filtering for phase and frequency of noisy oscillations: Application to vortex flow metering

A method for measuring the phase of oscillations from noisy time series is proposed. To obtain the phase, the signal is filtered in such a way that the filter output has minimal relative variation in the amplitude over all filters with complex-valued impulse response. The argument of the filter output yields the phase. Implementation of the algorithm and interpretation of the result are discussed. We argue that the phase obtained by the proposed method has a low susceptibility to measurement noise and a low rate of artificial phase slips. The method is applied for the detection and classification of mode locking in vortex flow meters. A measure for the strength of mode locking is proposed.

Learning Not to Curse: Swearing, Testimony, and Truth in Olaudah Equiano’s The Interesting Narrative

This article addresses swearing and testimony in Olaudah Equiano’s The Interesting Narrative (1789) by reading the work in the context of a broader contemporary discourse concerning profane swearing and cursing. Acts of profane enunciation inform a number of key episodes in Equiano’s life, and bear particular significance for his spiritual development and abolitionist witnessing. Within the Narrative, swearing is cast as a failure of piety, civility, and humanity, and shown to be actively avenged by a retributive deity. In Britain, profane swearing was also thought to undermine the validity of legal testimony; while, in the British West Indies, slaves were denied recourse to such testimony against their oppressors. By disavowing profane swearing and cursing, the essay argues, Equiano sought to assert both the validity of his oath and the truth of his testimony against the iniquities of the British slave trade.

Cause-specific mortality adjudication in the UPLIFT® COPD trial:findings and recommendations

Mortality is an important endpoint in chronic obstructive pulmonary disease (COPD) trials, although accurately determining cause of death is difficult. In the Understanding the Potential Long-term Impacts on Function with Tiotropium (UPLIFT®) trial, a mortality adjudication committee (MAC) provided systematic, independent and blinded assessment of cause-specific mortality of all 981 reported deaths. Here we describe this process of mortality adjudication and methodological revisions introduced to help standardise the adjudication of two areas recognised to pose particular difficulty; firstly, the classification of fatal COPD exacerbations that occur in the setting of pneumonia and secondly, the categorisation of sudden death. In addition MAC determined cause of death was compared with that reported by site investigators (SIs). MAC-assigned causes of death were: respiratory, 35%; cancer, 25%; cardiovascular, 11%; sudden cardiac death, 4.4%; sudden death, 3.4%; other, 8.8%; unknown, 12.4%. Cancer/cardiac deaths were more common in Global Initiative for Chronic Obstructive Lung Disease stage II, respiratory deaths in stages III and IV. Agreement between MAC and SI regarding cause of death was complete (50.2%), incomplete (18.5%) or none (31.3%). The SI classified deaths as cardiac three-fold more frequently than MAC (incidence rate [IR]/100 patient-years 0.797 vs. 0.257), although IR ratios for cardiac deaths for tiotropium vs. control were similar between SI and MAC. Discrepancies between MAC- and SI-adjudicated causes of death are common, especially increased reporting of cardiac deaths by the SI. Future multicentre COPD trials should plan appropriate infrastructure before study initiation to ensure collection and interpretation of fatal events data.

A Cat's Lick: Democratisation and Minority Communities in the Post-Soviet Baltic

The research on Estonia, Latvia and Lithuania has pointed out some controversial social and political developments since the collapse of the Soviet Union. Crucially, there is a discrepancy between the governments' commitment to creating democratic political regimes, to ensuring harmonious social relations and to accommodating the ethno-cultural diversity of the resident communities. In reflecting on the legacies of the Soviet past, the book addresses the role non-titular populations have played in the process of democratisation and the relation between the states, societies and minorities in the post-Soviet Baltic states. The argument proceeds along three lines. Firstly, the book examines the institutional dimension of democratisation in the region, thereby addressing the processes of state- and nation-building as reflected in various policy-developments. Secondly, it compares the impact of ethno-cultural diversity on the development of the respective Baltic nation-states. The discussion makes clear that the framework of Baltic political communities was designed to suit the interests of the titular groups and thus resulted in the marginalisation of the minority communities. Thirdly, the book assesses the participation of minority communities in the development, criticism and improvement of state institutions and policies since independence. The analysis points out that, two decades after independence, the post-Soviet Baltic states and societies are seen by many members of the majority groups as primarily serving the interests of their ethnic community. In this situation, the members of the non-titular communities need to adapt to the majorities' perceptions in order to benefit from the achievements of democratisation.

Zeros and Os:Silence, Absence and Erasure in an Intercultural O-thello

The performative function of sound and music has received little attention in performance theory and criticism and certainly much less so in studies of intercultural theatre. Such an absence is noteworthy particularly since interculturalism is an appropriative Western theatrical form that absorbs Eastern sources to re-create the targeted Western mise en scene. Consequently, a careful consideration of the employment of sound and music are imperative for sound and music form the vertebrae of Asian traditional performance practices. In acoustemological and ethnomusicological studies, sound and music demarcate cultural boundaries and locate cultures by an auditory (dis)recognition. In the light of this need for a more considered understanding of the performative function of sound and music in intercultural performance, this paper seeks to examine the soundscapes of an intercultural production of Shakespeare’s Othello – Desdemona. Directed by Singaporean Ong Keng Sen, Desdemona was a re-scripting of Shakespeare’s text and a self-conscious performance an identity politics. Staged with a multi-ethnic, multi-national cast, Desdemona employed various Asian performance traditions such as Sanskrit Kutiyattam, Myanmarese puppetry, and Korean p’ansori to create the intercultural spectacle. The spectacle was not only a visual aesthetic but an aural one as well. By examining the soundscapes of fractured silences and eruptive cultural sounds the paper hopes to establish the ways in which Desdemona performs absences and erasures of ‘Asia’ in a simultaneous act of performing an Asian Shakespeare.

Romanticism and Blackwood's Magazine:'An Unprecedented Phenomenon'

Romanticism and Blackwood's Magazine is inspired by the ongoing critical fascination with Blackwood's Edinburgh Magazine, and the burgeoning recognition of its centrality to the Romantic age. Though the magazine itself was published continuously for well over a century and a half, this volume concentrates specifically on those years when William Blackwood was at the helm, beginning with his founding of the magazine in 1817 and closing with his death in 1834. These were the years when, as Samuel Taylor Coleridge put it in 1832, Blackwood's reigned as 'an unprecedented Phenomenon in the world of letters.' The magazine placed itself at the centre of the emerging mass media, commented decisively on all the major political and cultural issues that shaped the Romantic movement, and published some of the leading writers of the day, including Coleridge, Thomas De Quincey, John Galt, Felicia Hemans, James Hogg, Walter Scott, and Mary Shelley.

'This much-needed volume reminds us not only why Blackwood's was the most influential periodical publication of the time, but also how its writers, writings, and critical agendas continue to shape so many of the scholarly concerns of Romantic studies in the twenty-first century.' - Charles Mahoney, Associate Professor, University of Connecticut, USA

Analysis of Betaine and Choline Contents of Aleurone, Bran, and Flour Fractions of Wheat (Triticum aestivum L.) Using 1H Nuclear Magnetic Resonance (NMR) Spectroscopy

In conventional milling, the aleurone layer is combined with the bran fraction. Studies indicate that the bran fraction of wheat contains the majority of the phytonutrients betaine and choline, with relatively minor concentrations in the refined flour. This present study suggests that the wheat aleurone layer (Triticum aestivum L. cv. Tiger) contains the greatest concentration of both betaine and choline (1553.44 and 209.80 mg/100 g of sample, respectively). The bran fraction contained 866.94 and 101.95 mg/100 g of sample of betaine and choline, respectively, while the flour fraction contained 23.30 mg/100 g of sample (betaine) and 28.0 mg/100 g of sample (choline). The betaine content for
the bran was lower, and the choline content was higher compared to previous studies, although it is known that there is large variation in betaine and choline contents between wheat cultivars. The ratio of betaine/choline in the aleurone fraction was approximately 7:1; in the bran, the ratio was approximately 8:1; and in the flour fraction, the ratio was approximately 1:1. The study further
emphasizes the superior phytonutrient composition of the aleurone layer.
INTRODUCTION
Wheat is a valuable source of betaine, choline (1, 2), B
vitamins, vitamin E, and a number of minerals, including iron,
zinc, magnesium, and phosphorus (3). Epidemiological studies
indicate that whole-grain consumption is protective against
several chronic diseases (4-12). It has not been fully elucidated
how whole-grain cereals or specific fractions (13) exert their
protective effect, but it is thought to be due to their content of
several nutrients associated with the reduced risk of disease.
Conventionally, whole grain is separated during milling into
bran, germ, and flour (14). The nutrient composition of these
fractions differ markedly; refined wheat flour contains approximately
50% less vitamins and minerals than whole-grain
flour (
