Abstract

Objective: To evaluate whether medical personnel differ from the general population in obstetrical and perinatal outcomes.

Materials and methods: The participants comprised 46 physicians and 116 nurses employed at one medical center who gave birth in its maternity hospital. General medical and obstetrical data on their latest (“index”) pregnancy and delivery were extracted from real-time computerized patient files. The control group included 162 women who gave birth during the same period in the same hospital.

Results: The study group had significantly more deliveries, cesarean sections, and terminations of pregnancy prior to the index pregnancy. The medical personnel conceived significantly more often with assisted reproductive technologies (ART) (18.8% vs. 8% for controls, P<0.05), and had significantly more obstetrical complications, i.e., premature contractions, gestational diabetes mellitus, preeclamptic toxemia, and 2nd/3rd trimester bleeding or chorioamnionitis (42.5% vs. 29% for controls, P<0.05). The rate of vaginal birth after cesarean delivery (VBAC) was lower in the study group (22.2% vs. 33.3% for controls, P=0.03). There was no difference in gestational age at delivery, birth weight, or adverse neonatal outcome.

Conclusions: Medical personnel utilized ART more frequently and had more pregnancy complications as well as a lower incidence of VBAC than non-personnel. Neonatal outcomes were similar for both groups.
Incorporating first trimester analytes to predict delivery of a large for gestational infant in women with impaired glucose tolerance

Published: May 2014

Abstract

Aim: To investigate first trimester maternal characteristics of women with impaired glucose tolerance that deliver large for gestational age (LGA) infants.

Methods: Nested analysis from a prospective study of singleton pregnancies enrolled at first trimester. We studied women with an abnormal 1 h glucose challenge test that had normal follow-up oral glucose tolerance testing. Maternal characteristics, ultrasound parameters and serum analytes were stratified by subsequent delivery of an LGA infant. Parameters identified as significant on univariate analysis were used for a derivation of prediction by logistic regression. Odds ratio and prediction performance was determined using receiver operator curve (ROC) statistics.

Results: A total of 33/114 (28.9%) women meeting the criteria delivered LGA infants. Maternal height (cm), and first trimester pregnancy-associated protein-A and free β-hCG (MoM) predicted delivery of an LGA infant (ROC area under curve 0.73; 95% CI 0.63–0.83). At a cutoff value of 0.172 the prediction rule achieved 91% sensitivity, 44% specificity, 41% positive predictive and 92% negative predictive value.

Conclusion: Maternal height and first trimester high free β-hCG and PAPP-A levels may be used as predictors for delivery of LGA infants in women with impaired glucose tolerance.
High performance computing in quantitative finance: A review from the pseudo-random number generator perspective

Abstract.
The great demand for high computational capabilities is omnipresent in every facet of modern financial activities, ranging from financial product pricing, trading and hedging at the front desk on the one end to risk management activities for in house monitoring and legislative compliance on the other. While this demand is met by scalable high performance computing, along with it come new challenges. As a notable proportion of financial computations involve the use of pseudo-random numbers, the engagement of a large number of parallel threads leads to consumption of large amount of pseudo-random numbers, uncovering potential intra-thread and inter-thread correlation that will lead to bias and loss of efficiency in the computation. This paper reviews, in the setting of derivative instrument pricing, the performance of some commonly used scalable pseudo-random number generators constructed based on different parallelization strategies: (1) parameterization (SPRNG), (2) sequence-splitting (TRNG and RngStream), and (3) cryptography (Random123). In addition, the potential impact of intra-thread and inter-thread correlation in pricing and sensitivity analysis of some common contingent claims via Monte Carlo simulation is examined.

Manufacture and characterization of conductor-insulator composites based on carbon nanotubes and thermally reduced graphene oxide
Authors: Bowen Chris R. , Buschhorn Sam , Adamaki Vana 
Published: May 2014

AbstractIn this paper we present characterization data for carbon nanotube (CNT)-epoxy and thermally reduced graphene oxide (TRGO)-epoxy nano-composites. The frequency-dependent ac conductivity and permittivity are examined as a function of volume fraction of carbon-based filler. The measured electrical properties and their frequency dependency are evaluated on the basis that such composites can be considered as a network of resistors and capacitors, whereby the resistors represent the conductive component (CNT or TRGO) and the capacitors are the insulating component (epoxy matrix). Differences observed between the frequency-dependent electrical properties of the CNT-epoxy and TRGO-epoxy composites are explained in terms of the different electrical conductivities of the CNT and TRGO phase.
Mechanical and barrier properties of copolyester-nanoclay composites
Authors: Mohan Turup P. , Kanny Krishnan 
Published: May 2014

Abstract
This paper examines the influence of nanoclay on the structure, thermal and mechanical and gas barrier properties of a polyethylene terephthalate (PET)-based copolyester using a new modified formula. The copolyester considered in this work consists of partially replaced acid and diol monomers in main chain PET polymers, namely, polyethylene glycol (PEG) and isophthalic acid monomers, i.e., PET-IP. Nanoclays were filled from 0–3 wt% in PET-IP using the melt mixing method. The structural examination of composites tested by X-ray diffraction (XRD) and transmission electron microscopy (TEM) revealed the distribution of nanolayers of clay particles in polymeric matrix. Up to 1 wt% nanoclay in PET-IP, an exfoliated structure resulted and above 1 wt% nanoclay an intercalated structure resulted. It was observed that 0.5 wt% nanoclay filled PET-IP resulted in improved nucleation characteristics and above 0.5 wt% nanoclay dramatically increased the gas transport (CO2, O2, N2 and water vapor), thermal and mechanical properties. The results also showed that the distribution of nanoclays affected the gas barrier properties of the polymer and can be controlled by processing parameters.
Modeling of cesium sorption on biotite using cation exchange selectivity coefficients
Authors: Kyllönen Jarkko , Hakanen Martti , Lindberg Antero , Harjula Risto , Vehkamäki Marko , Lehto Jukka 
Published: May 2014

Abstract
For the modeling of cesium sorption on biotite, samples of natural biotite separated from gneissic rocks were converted into monoionic
potassium, sodium, and calcium forms, and sorption isotherms for Cs/K, Cs/Na and Cs/Ca exchange were determined at pH 6 and 8 in
E-4–E-8 M Cs solutions. Selectivity coefficients for Cs/K, Cs/Na, and Cs/Ca ion exchange reactions were calculated from
the isotherm data, using the Gaines-Thomas convention. At Cs loadings below 1% of the total ion exchange capacity, the overall
selectivity coefficient for Cs/Ca exchange was approximately five and seven orders of magnitude higher than those for Cs/Na and Cs/K
exchange, respectively. Based on the selectivity coefficients, the ion exchange isotherms were modeled with the U.S. Geological Survey
PhreeqC program, assuming three different types of ion exchange site: sites on the basal planes on biotite crystal surfaces with
95% site abundance, probable interlayer sites on crystal edges [frayed edge sites (FESs)] (0.02%) and third-type
sites (5%), the physical background of which is unclear. Of these three types, the FES sites were superior in Cs selectivity,
while the planar sites exhibited the lowest selectivity, and the third-type sites had selectivity between these two. The functionality
of the model was successfully verified by modeling the Cs sorption isotherms on crushed mica gneiss rock in saline
groundwater. Determination of the exchangeable ions K, Na, Ca, and Cs on the basal plane and edge surfaces by scanning electron
microscopy-energy-dispersive x-ray spectroscopy (SEM-EDX) supports the results of modeling: edge sites highly prefer Cs ions and also
Ca and Na ions but not K ions.
Development of a new method for design of stiffened composite pressure vessels using lattice structures
Authors: Taghavian Seyed Hossein , Jam Jafar Eskandari , Zabihpoor Mahmood , Yousefzadeh Mahdi 
Published: May 2014

AbstractA new method to design composite pressure vessels under strain and strength constraints using lattice structures is described. A graphical analysis is presented to find the optimum geometrical parameters of the rib for given fiber orientations. Minimum pressure vessel mass is determined from active execution of two constraints. Composite lattice structures are suggested as a new way of strain suppression among the commonly used methods such as (1) addition of extra plies, (2) use of composite material with a higher stiffness and (3) replacement of the circumferential layer with a second helical layer made of different materials. The experimental and analytical results of application of the method indicate that the vessel covered with composite lattice structures presented considerable weight savings with respect to traditional stiffened vessels.
Term spread regressions of the rational expectations hypothesis of the term structure allowing for risk premium effects
Authors: Argyropoulos Efthymios , Tzavalis Elias 
Published: May 2014

AbstractThis paper suggests a new empirical methodology of testing the predictions of the term spread between long and short-term interest rates about future changes of the former allowing for term premium effects, according to the rational expectations hypothesis of the term structure. To capture the effects of a time-varying term premium on the term spread, the paper relies on an empirically attractive affine Gaussian dynamic term structure model which assumes that the term structure of interest rates is spanned by three unobserved state variables. To retrieve accurate values of these variables from interest rates series, the paper suggests a new method which can overcome the effects of measurement (or pricing) errors inherent in these series on the estimates of the model. This method is assessed by a Monte Carlo study. Ignoring these errors will lead to biased estimates of term structure models. The empirical results of the paper provide support for the suggested term structure model. They show that this model can efficiently capture the time-varying term premium effects embodied in long-term interest rates, which can explain the failures of term spread to forecast future changes in long-term rates.

Abstract
Recently the Joo-type heterodyne interferometer was invented to overcome the
periodic nonlinearity, but there was less discussion about the optics
thermal drift of Joo-type interferometer. In this paper, the optics thermal
drift model of Joo-type interferometer is established, and a highly stable
heterodyne interferometer is proposed. Experimental results show that, the
proposed interferometer's periodic nonlinearity is 0.035 nm, while its
optics thermal drift coefficient is 18 nm/℃ approximately.

A RATHER LIMITED AFFAIR THE USES OF THEORY FOR DRAMATURGES AND TRANSLATORS OF PLAYS
Authors: Raab Michael 
Published: May 2014

Abstract
From a practitioner's point of view the essay tries to give an account of the financial side of translating for the theatre, the author's work on the German versions of new British and Irish plays as a dramaturge and productions of his own translation of Mark O'Rowe's Howie the Rookie. These practical considerations are set against some of the criteria developed by theory for the process of translation and its necessary degree of faithfulness to the original. Finally some suggestions are made how to narrow the gap between theory and theatre practice.
Intertextuality and History: America's Colonial Past in The Scarlet Letter (1995)
Authors: Obenland Frank 
Published: May 2014

Abstract
This essay discusses the representation of New England's colonial past in the most re cent cinematic adaptation of Nathaniel Hawthorne's novel The Scarlet Letter (185.0). Based on theoretical models developed by Renate Lachmann, this essay will show that the movie creates an effect of historicity in developing a web of intertextual references between the cinematic adaptation of The Scarlet Letter and a number of historical and literary documents. The intertextual structure of the film determines the cinematic recreation of the past and succeeds in simultaneously reconstructing different historical crises in American colonial history.
The Cultural Validity of Classical Music in Richard Powers’s The Time of Our Singing
Authors: Sauerberg Lars Ole 
Published: May 2014

Abstract
Richard Powers’s novel The Time of Our Singing (first published 2003) is a fictional prose narrative about the musical careers of two brothers of African-American and German-Jewish parentage in a social context affected by racial issues in twentieth-century USA. The novel explores music in terms of cultural and political appropriation and demonstrates, in the laboratory of fiction, the extent to which racial prejudice influences the use of and attitudes towards musical conventions. While, at the level of fabula, the musical careers of the two brothers are predestined to failure by their refusal to comply with ingrained social mores, the novel, at the level of sujet, nonetheless problematizes the notion of music as a pure social/cultural construct and, with the tragic plot, presents a case in favour of music as a redemptive aesthetic force transcending historically determined realities. This is brought about by a richly suggestive discourse full of descriptions and metaphors evoking inherently musical values.
Performing Jazz, Defying Essence: Music as a Metaphor of Being in Jackie Kay’s Trumpet
Authors: Eckstein Lars 
Published: May 2014

Abstract
The cultural validity of jazz has been evaluated very differently by various critical camps. Some voices try to essentialise jazz by either claiming it as a specifically African American tradition dominated by black, and mostly male musicians, or, alternatively, by explicitly limiting its cultural functionality to the black diaspora. Other voices, in contrast, insist on the hybrid genealogy and dialogic openness of jazz as a form of art that inherently defies boundaries of gender and race. Jackie Kay’s novel Trumpet fully subscribes to the latter opinion. Revolving around the jazz musician Joss Moody, Trumpet not only takes up jazz as a core theme but also refers to jazz-aesthetic principles and performative arrangements in its narrative design. Most importantly, however, Trumpet uses jazz as a metaphor of being, as a model of identity formation that privileges a performative approach to the social and biological constraints of gender and race
'After London': The Death of the Metropolis in the Fiction of Richard Jefferies
Authors: Lindner Oliver 
Published: May 2014

Abstract
In the late nineteenth century, urban spaces attracted increasing criticism. Against the backdrop of environmental pollution, the miserable housing conditions of the poor and fears of degeneration, the metropolis came under close examination. Late Victorian writers responded to this discussion in particular. The essay investigates the representation of urban disorders in the works of Richard Jefferies. As a critic of industrialized society, Jefferies powerfully articulated a possible future of London in some of his shorter prose fiction and in his novel After London; or, Wild England (1885). Whereas his short story "Snowed Up" (1876) and the fragment "The Great Snow" (1876) portray a temporary 'death' of the city resulting from tremendous snowstorms, After London presents a complete overthrow of urban structures. Jefferies's pessimistic outlook on the future of the city will be analysed and brought within the context of other fictional texts of the period, which also focus on the future of London.
John Keats and Mythopoetics: A Reading of "La Belle Dame sans Merci"
Authors: Baumbach Sibylle 
Published: May 2014

Abstract
While the tide of Keats's "La Belle Dame sans Merci" points to Alain Chartier's medieval poem as major source, there is an even earlier subtext suggesting itself in both the ballad's narrative and structure. As demonstrated in this paper, Keats's depiction of the relationship between the knight and the fairy-figure, between poetic ward and mysterious muse, ,refers to the myth of Orpheus and Eurydice as it is presented in Ovid's Metamorphoses. Exceeding what can be regarded a fine example of creative reception, the recurrence to the classical tale of poetic inspiration and, as it were, despair adds a metapoetic level to "La Belle Dame." Playing on in a world that is depicted as having fallen silent, the ballad becomes a means for reviving orphic singing and enacts an encounter with antiquity, in which the poet's anxiety of belatedness is eventually overcome. Thereby Keats emerges as another Ovid or even a new writing, writing himself into a greater tradition of mythopoetry
No More Room in Hell: Utopian Moments in the Dystopia of 28 Days Later
Authors: Heinze Rüdiger , Petzold Jochen 
Published: May 2014

Abstract
Focusing on the zombie-film 28 Days Later (Danny Boyle) may at first sight seem an odd choice in the context of utopian writing, but links to utopia can in fact be drawn on various levels. Zombies, like utopia itself, can function as a means to comment on or criticize present society; the creation of zombies in 28 Days Later is linked to an utopian ideal, the elimination of rage; and the film can be read as a quest for a utopian space in a pastoral setting. Thus, the film is discussed as a self-referential mixture of genres that combines dystopia with apocalypse, utopia with the pastoral, and that ironically undercuts all its generic statements.
The ‘Search for Order’ and the Crisis of Masculinity: The Naturalist American Novel and the Cultural Anxieties of the ‘Strenuous Age’
Authors: Müller Kurt 
Published: May 2014

Abstract
This article discusses the American naturalist novel both as a reflection of and a reaction to the symptoms of cultural crisis around 1900. By the turn of the century, the modernization process had led to a widespread sense of uprootedness and disorientation, often resulting in feelings of displacement, anxiety, and identity diffusion, not least in terms of 'gender trouble: That, in turn, generated a strong need for stabilizing structures of order, control, and power. This need is reflected in the naturalist ecriture, which signifies a massive claim for power and control over the fictional material and over the reader, as well as in terms of plot construction and character conflict. Taking NOTTis's McTeague (1899) as a major example, the article demonstrates how the characters of that novel are motivated by an anxiety-ridden "search for order" (Wiebe t 967) and at the same time involved in a gender conflict constellation that is indicative of the crisis of masculinity that was part of the socio-psychological substratum of the 'strenuous age:
“Tell Nannan I Walked”: Reconstructing Manhood in Ernest J. Gaines's A Lesson before Dying
Authors: Crisu Corina Anghel 
Published: May 2014

Abstract
Drawing on a variety of philosophical and ethical views, as well as on African American studies, this paper discusses the way in which Emest J. Gaines's A Lesson
before Dying reconsiders the black male character in the context of racial prejudices in the segregated South in the late 1940s. The paper demonstrates that Gaines is one of the authors who had to face the difficult task of transforming the invisible African American presence into the central element of his narrative. From a silent, subjugated figure, from being simply a substitute of the white man, the black protagonist metamorphoses into a polytropic character. The article proposes a close textual and intertextual analysis of Gaines's reconstruction of black male identity. The main argument focuses on the way in which Gaines rewrites the earlier representation of the lonely rebellious African American - (de )constructing the image of the native son and invisible man - by insisting on the importance of the pedagogical role of the community.
