Published: July 2019

AbstractThe aim of this study was to evaluate the morphologic appearance, the clinical scenario, and the outcomes of patients with portal hypertensive biliopathy (PHB), particularly in the symptomatic subgroup treated with interventional radiology (IR) procedures. The outcome of 20 patients with PHB were retrospectively reviewed over a 5-year period. In all cases, the extrahepatic portal vein occlusion (EHPVO) and the compensatory cavernomatosis was the cause of PHB. Eight out of 20 patients had severe symptoms (jaundice and bleeding). Five out of these eight patients were successfully treated with IR procedures. PHB is a rare but serious complication of PH from EHPVO. IR treatments are highly effective in controlling symptoms. Moreover, IR procedures, as drainage and transjugular intrahepatic portosystemic shunt placement, are the first-line treatment in cases of life-threatening bleeding from ruptures of the varices.
Gay rights as a symbol of ideological struggles between Russia and the West
Authors: Koller Veronika 
Published: July 2019

Abstract
This chapter will investigate how two news articles, from the British Guardian and from Russia Today, report on the issue of gay rights in Russia, as mentioned in a press conference given by Russian president Putin in the run-up to the 2014 Winter Olympics in Sochi. The analysis will employ a socio-cognitive approach to critical discourse studies. Similarities and differences in social actor representation and cohesion in the two texts will be explained as illustration that both Putin and the writers of the articles seek to engage in strategic ideological communication to effect social categorisation, construct in-groups and out-groups, and design their texts for particular audiences. The findings will be discussed against a background of increasing geopolitical and ideological tensions between Russia and some Western countries.
Impoliteness in parliamentary questions
Authors: Nowak Bartholomäus 
Published: July 2019

Abstract
This chapter aims to examine Polish parliamentary discourse by linking (im)politeness theory with approaches describing questions. To achieve this, a corpus from four Polish Question Times was created, analyzing the degree of impoliteness in all of the 336 questions contained within it. In order to minimize the uncertainty of interpretations concerning the politicians’ intentions, scholarly literature from political sciences on parliamentary questions was also applied. Overall, the quantitative analysis revealed a high occurrence of face threatening acts via questions, and a substantial difference according to the political orientation of the opposition. The use of impolite questions by the right-wing opposition far exceeds the use of similar questions by the left-wing opposition. The qualitative analysis shows the full range of impolite questions, from weakest to strongest. Even within the ruling coalition, MPs deal with face threatening questions attacking their “own” government. They mitigate the face threat by using, for example, indirect formulations or the conditional mood. Apart from that, MPs pose partisan questions which enhance the face of their party’s ministers and simultaneously damage the one of the opposition.
Discursive construction of ‘Us’ and ‘Them’
Authors: Riehn Sonja 
Published: July 2019

Abstract
Commemorative speeches as an annual ritual play an important role in the memory discourse of a society. They construct political and social realities, as well as a collective identity. The following paper discusses the content and the form of official remembrance of the Homeland War in Croatia, which took place from 1991 to 1995. In particular, I will focus on the constitution of the elements of national identity and collective memory of the 1990s within the selected speeches of Croatian political leaders between 2004 and 2016. Hereby, the emphasis is on the discursive presentation of Self and Others. The analysis draws on theoretical and methodological frameworks of the Discourse-Historical Approach within the Critical Discourse Analysis.
‘Like a donkey carrying books’
Authors: Badarneh Muhammad A. 
Published: July 2019

AbstractThis study aims to show how intertextuality is exploited as an impoliteness resource in online reader comments on the website of a London-based pan-Arab Arabic-language daily newspaper. Analysis of 140 reader responses containing impolite references shows that readers called upon and appropriated the language and imagery of impolite and culturally salient prior texts from four sources to perform impoliteness: traditional scriptures, historical texts, poetic texts, and popular proverbs. The use and reception of these impolite intertextualities rely on familiarity with the intertextual source in question. The creative recycling of privileged authoritative texts, use of metaphorical language, invoking of gender identity, and reproducing of particular ideologies played a pivotal role in performing this intertextual impoliteness. The perception of such intertextual impoliteness is crucially influenced by culture as a “general text” (Kristeva 1980) that adds to the complexity of impoliteness when analyzed within a culture-specific context.

Abstract
This article considers the sonic construction of place in English folk music recordings.
Recent shifts in the political context have stimulated renewed interest in English identity within folk music
culture. Symbolic struggles over folk’s political significance highlight both the contested nature of English
identity and music’s semantic ambiguity, with texts being interpolated into discourses of both ethnic purity
and multiculturalism. Following research in popular music, sound studies and multimodal communication this
article explores the use of field recording to explore questions of place and Englishness in the work of
contemporary folk artists. A multimodal analysis of Stick in the Wheel’s From Here: English Folk Field
Recordings (2017) suggests that a multimodal approach
to musical texts that attends to the semantic affordances of sound recording can provide insight into folk
music’s role in debates over the nature of English identity.
The dynamics of Nepali pronominal distinctions in familiar, casual and formal relationships
Authors: van Driem George L. 
Published: July 2019

Abstract
Nepali uses various morphological means formally to distinguish at least five levels of deference in verbal interaction. In addition to the three Nepali second person pronouns, for each of which the Nepali verb distinguishes separate conjugated forms, Nepali speakers also make use of the deferentially conjugated verb in combination with the respectful term hajur or with kinship terms to give expression to different levels of deference and formality. Moreover, the Nepali verb distinguishes a separate mediopassively conjugated construction used exclusively when the notional subject of the sentence is a member of the former royal family. Speakers can also exploit the device of the ambiguous avoidance term āphu ‘self’ or make oblique reference to the second person through the use of the first person plural when a speaker is uncertain of the register which would be most appropriate.
Unlike the simple two-term system found in many Western languages, such as French tu vs. vous, the choice of pronoun and conjugation between intimate friends and indeed between higher caste married couples tends to be highly asymmetrical. The semiotics of this asymmetry is commensurate with the degree of intimacy which the two individuals feel towards each other. This phenomenon, strikingly unfamiliar to the contemporary Occidental, illustrates rather vividly how different the sensibilities and semantic underpinnings of the many tiers of deference expressed by pronominal usage and other morphological parameters in Nepali are from those of an intimate interaction whereby the two European individuals might simply be able to tutoyer each other. A descriptive account is provided of actual usage, and an analytical exposition of the semiotics of this morphologically diverse system of indexing relationships in Nepali speech is presented.
The Chinese pronominal system and identity construction via self-reference
Authors: Xue Bing , Zhang Shaojie 
Published: July 2019

Abstract
In the Chinese pronominal system, the first-person singular pronoun wǒ is the unmarked or grammatical form of the speaker’s reference to himself/herself, which is deictic in nature. In daily conversation, however, other deictic expressions such as plural first-person and second-person pronouns, and even non-deictic proper names and descriptive expressions, can be employed to convey self-referential meanings. By analyzing the data collected from an authoritative Chinese corpus, we claim that self-reference is not merely the marking of the speaker’s participant role but a process of identity foregrounding or ad hoc identity construction exploited by the speaker in communication. This identity construction via self-reference reflects the dynamics and complexity of self-reference in verbal interaction.
Pronouns in affinal avoidance registers
Authors: Kruspe Nicole , Burenhult Niclas 
Published: July 2019

Abstract
Affinal avoidance registers are strategies of restrained linguistic conduct in relation to one’s in-laws. Current theories are primarily concerned with two types of strategies: (1) taboos on uttering the proper names of affines, and (2) substitution of everyday words with dedicated parallel lexicon in the presence of affines (so-called “mother-in-law languages”). However, the role of pronouns has received limited attention. Here we explore little-known registers in the Aslian languages (Austroasiatic, Malay Peninsula), where dedicated pronoun paradigms take centre stage in communication with and about in-laws. We characterise and compare these closely related but internally diverse systems, situate them in their cultural contexts, and discuss their status in relation to current theories and typologies of avoidance and honorific registers.

Abstract
Transport modelling of Joint European Torus (JET) dimensionless collisionality scaling experiments in various operational scenarios is presented. Interpretative simulations at a fixed radial position are combined with predictive JETTO simulations of temperatures and densities, using the TGLF transport model. The model includes electromagnetic effects and collisions as well as

shear in Miller geometry. Focus is on particle transport and the role of the neutral beam injection (NBI) particle source for the density peaking. The experimental 3-point collisionality scans include L-mode, and H-mode (D and H and higher beta D plasma) plasmas in a total of 12 discharges. Experimental results presented in (Tala et al 2017 44th EPS Conf.) indicate that for the H-mode scans, the NBI particle source plays an important role for the density peaking, whereas for the L-mode scan, the influence of the particle source is small. In general, both the interpretative and predictive transport simulations support the experimental conclusions on the role of the NBI particle source for the 12 JET discharges.
Enhanced ponderomotive force in graphene due to interband resonance
Authors: Wolff C , Tserkezis C , Mortensen N Asger 
Published: July 2019

Abstract
We analyze intrinsic nonlinearities in two-dimensional (2D) polaritonic materials interacting with an optical wave. Focusing on the case of graphene, we show that the second-order nonlinear optical conductivity due to carrier density fluctuations associated with the excitation of a plasmon polariton is closely related to the ponderomotive force due to the oscillating optical field. A recent study (Sun et al 2018 Proc. Natl Acad. Sci. USA
115 3285–9) derived this force in the hydrodynamic regime of a generic Dirac fluid, and suggested that inclusion of interband transitions could have interesting implications. Here we reproduce the Drude-like result in a more general fashion on the basis of thermodynamics, which makes extension to other regimes straightforward. We find that for zero temperature a diverging nonlinearity is found at the interband threshold. By including finite-temperature effects this is regularized, but remains quite significant even at room temperature. Going further beyond, we include nonlocal corrections as a second potential source of regularization, and find that they do not lead to broadening (as one would usually expect e.g. due to Landau damping), but rather to a splitting of the ponderomotive interband resonance, providing a very characteristic signature of nonlocality. Our analysis should prove useful to the open quest for exploiting nonlinearities in graphene and other 2D polaritonic materials, through effects such as photon drag.
Laser cooling with adiabatic transfer on a Raman transition
Authors: Greve G P , Wu B , Thompson J K 
Published: July 2019

Abstract
Sawtooth Wave Adiabatic Passage (SWAP) laser cooling was recently demonstrated using a narrow-linewidth single-photon optical transition in atomic strontium and may prove useful for cooling other atoms and molecules. However, many atoms and molecules lack the appropriate narrow optical transition. Here we use such an atom, 87Rb, to demonstrate that two-photon Raman transitions with arbitrarily-tunable linewidths can be used to achieve 1D SWAP cooling without significantly populating the intermediate excited state. Unlike SWAP cooling on a narrow transition, Raman SWAP cooling allows for a final 1D temperature well below the Doppler cooling limit (here, 25 times lower); and the effective excited state decay rate can be modified in time, presenting another degree of freedom during the cooling process. We also develop a generic model for Raman Landau–Zener transitions in the presence of small residual free-space scattering for future applications of SWAP cooling in other atoms or molecules.
Single-trajectory spectral analysis of scaled Brownian motion
Authors: Sposini Vittoria , Metzler Ralf , Oshanin Gleb 
Published: July 2019

Abstract
A standard approach to study time-dependent stochastic processes is the power spectral density (PSD), an ensemble-averaged property defined as the Fourier transform of the autocorrelation function of the process in the asymptotic limit of long observation times,

T
→
∞

. In many experimental situations one is able to garner only relatively few stochastic time series of finite T, such that practically neither an ensemble average nor the asymptotic limit

T
→
∞

can be achieved. To accommodate for a meaningful analysis of such finite-length data we here develop the framework of single-trajectory spectral analysis for one of the standard models of anomalous diffusion, scaled Brownian motion. We demonstrate that the frequency dependence of the single-trajectory PSD is exactly the same as for standard Brownian motion, which may lead one to the erroneous conclusion that the observed motion is normal-diffusive. However, a distinctive feature is shown to be provided by the explicit dependence on the measurement time T, and this ageing phenomenon can be used to deduce the anomalous diffusion exponent. We also compare our results to the single-trajectory PSD behaviour of another standard anomalous diffusion process, fractional Brownian motion, and work out the commonalities and differences. Our results represent an important step in establishing single-trajectory PSDs as an alternative (or complement) to analyses based on the time-averaged mean squared displacement.
Expanding the Lorentz concept in magnetism
Authors: Bowden G J , van der Laan G , Hesjedal T , Hicken R J 
Published: July 2019

Abstract
In 1878, the Dutch physicist Hendrik Antoon Lorentz first addressed the calculation of the local electric field at an atomic site in a ferroelectric material, generated by all the other electric dipoles within the sample. This calculation, which applies equally well to ferromagnets, is taught in Universities around the World. Here we demonstrate that the Lorentz concept can be used to speed up calculations of the local dipolar field in square, circular, and elliptical shaped monolayers and thin films, not only at the center of the film, but across the sample. Calculations show that long elliptical and rectangular films should exhibit the narrowest ferromagnetic resonance (FMR) linewidth. In addition, discrete dipole calculations show that the Lorentz cavity field

does not hold in tetragonal films. Depending on the ratio (b/a), the local field can be either less/greater than

an observation that has implications for FMR. 3D simple cubic (SC) systems are also examined. For example, while most texts discuss the Lorentz cavity field in terms of a Lorentz sphere, the Lorentz cavity field still holds when a Lorentz sphere is replaced by a the Lorentz cube, but only in cubic SC, FCC and BCC systems. Finally, while the primary emphasis is on the discrete dipole–dipole interaction, contact is made with the continuum model. For example, in the continuous SC dipole model, just one monolayer is required to generate the Lorentz cavity field. This is in marked contrast to the discrete dipole model, where a minimum of five adjacent monolayers is required.
How does gendered vulnerability shape the adoption and impact of sustainable livelihood interventions in an era of global climate change?
Authors: Call Maia , Sellers Samuel 
Published: July 2019

Abstract

Background. Though many studies have long considered the broad social implications of climate change, researchers have only recently started to consider the gendered unevenness of the global landscape of vulnerability, exposure, and adaptive capacity to environmental stressors and shocks. Historically, policies and interventions addressing natural resource-based livelihoods have rarely considered underlying gender dynamics despite the global pervasiveness of gendered disparities in both economic opportunities and welfare outcomes. Methods/Design. Using two electronic databases, Web of Science and Scopus, we conducted a systematic review of peer-reviewed academic literature describing livelihoods policies or interventions that included documentation of gendered impacts. We focused on natural resource-based livelihoods most likely to be affected by climate change, centering on interventions targeting agriculture, fisheries and aquaculture, and forestry. Review Results/Synthesis. We identified 131 relevant articles, most of which focus on adoption or participation in interventions rather than outcomes. In general, women are less likely than men to engage with sustainable livelihoods interventions. When women do engage, some researchers have documented income and food security gains as well as improvements in environmental indicators in the short-term. However, these initiatives have also been found to increase women’s labor burden without corresponding gains in income. Few studies measure longer-term effects of women’s engagement on welfare and environmental outcomes, a key gap in the literature. Additionally, relatively few studies explore the intersectional impacts of initiatives, such as the added burdens of ethnicity, class, education, or other differences that modify gender disparities. Discussion. Climate change has gendered impacts on natural resource-based livelihoods. In general, existing initiatives designed to increase livelihood resilience fail to reduce gender disparities and improve women’s livelihoods. Greater attention should be paid to gender when designing sustainable livelihoods policies and interventions in order to increase adoption and participation, negotiate trade-offs, improve environmental conditions, and promote broadly beneficial welfare outcomes.
Characterizing multipartite entanglement classes via higher-dimensional embeddings

Published: July 2019

Abstract
Witness operators are a central tool to detect entanglement or to distinguish among the different entanglement classes of multiparticle systems, which can be defined using stochastic local operations and classical communication (SLOCC). We show a one-to-one correspondence between general SLOCC witnesses and a class of entanglement witnesses in an extended Hilbert space. This relation can be used to derive SLOCC witnesses from criteria for full separability of quantum states; moreover, given SLOCC witnesses can be viewed as entanglement witnesses. As applications of this relation we discuss the calculation of overlaps between different SLOCC classes and the SLOCC classification in

-dimensional systems.
Oxidation by Hydrogen Peroxide Changes Crystallinity and Physicochemical Properties of Banana Flour

Published: July 2019

Abstract
Banana flour var nangka has been oxidised using hydrogen peroxide at concentration of 1 to 3 % using native banana flour as a control. Functional and pasting properties and the change in crystalline type have been compared following the modification. Investigation using XRD showed that oxidation by hydrogen peroxide decreased the crystallinity from 56.9% in the native to around 52% in the oxidised flour. The crystalline type however remained unchanged (B type). There was no remarkable difference of properties following oxidation at various concentration of hydrogen peroxide, suggesting that the smallest concentration in the present study (1%) was sufficient to modify the banana flour. In terms of functional properties, oxidation increased swelling volume, freeze thaw stability and gel strength but decreased solubility, water absorption capacity and whiteness degree. Other parameters of pasting properties were not significantly affected by oxidation in the present range of concentration except the setback and breakdown viscosity which decreased compared to the native flour.
Sharia Microfinance Institutions Financing Model for Strengthening Agricultural Sector

Published: July 2019

AbstractThe agricultural sector is a sector that has a strategic role in economic development in Indonesia. However, the agricultural sector has several problems such as less secure of farmers’ welfare, low access to capital and marketing of crops. The existence of farmers’ groups and Sharia Microfinance Institutions (LKMS) has not been able to optimize the potential of the agricultural sector. The purpose of this study is to formulate a strengthening model from institutional aspects through local farmers’ groups and capital strengthening through the inter mediation of Sharia Financial Institutions (LKS) through a linkage program. The model of institutional strengthening of farmers’ groups and capital ofLKSfinancing can be one of the foundations of national economic development. This study used a qualitative approach. Data were collected from the results of in-depth interviews, focus group discussions (FGD) and questionnaires. This study examines: (1) strengthening of farmers’ group institutions; (2) development of the agricultural sector financing model through inter mediation between localLKSandLKMSand linkage programs between farmers’ groups andLKMS
