Ilja Leonard Pfeijffer as a Luxury Immigrant: A European Public Intellectual and the ‘Refugee Crisis’
Creators: name: Beeks, Sarah
Publisher: name: FKW // Zeitschrift für Geschlechterforschung und visuelle Kultur
Year: 2019

description: Central to this article is the Dutch poet and writer Ilja Leonard Pfeijffer who in recent years has positioned himself explicitly as a European intellectual. Using Odile Heynders’ definition of the public intellectual, it examines the ways in which Pfeijffer has contributed to the public debate on the so-called ‘refugee crisis’ in and beyondhis literary works. By means of a close reading of Brief aan Europa [Letter to Europe] (2015), the article examines the literary tools with which Pfeiffer tries to add complexity to this debate, for instance techniques such as personification, focalization and identification. In his literary writings Pfeijffer seems to prompt his readers to rethink their luxury position and to direct their attention to the complex issues underlying the ‘refugee crisis’. Simultaneously, however, he also uses images that appear rather problematic and result in stereotyping. Finally, the article also touches upon the more general difficulties of writing on the ‘refugee crisis’ today. Is a Western, privileged writer like Pfeijffer allowed to use the stories of refugees for his own economic benefit? By looking into his public position and performances, the article shows that his economic success and cultural authority are intricately connected to his position as a public intellectual writing on the ‘refugee crisis’.

description: We carried out a magnetohydrodynamics simulation where a subsurface twisted kink-unstable flux tube emerges from the solar interior to the corona. Unlike the previous expectations based on the bodily emergence of a knotted tube, we found that the kinked tube can spontaneously form a complex quadrupole structure at the photosphere. Due to the development of the kink instability before the emergence, the magnetic twist at the kinked apex of the tube is greatly reduced, although the other parts of the tube is still strongly twisted. This leads to the formation of a complex quadrupole structure: a pair of the coherent, strongly twisted spots and a narrow complex bipolar pair between it. The quadrupole is formed by the submergence of a portion of emerged magnetic fields. This result is relevant for understanding of the origin of the complex multipolar $δ$-spot regions that have a strong magnetic shear and emerge with polarity orientations not following Hale-Nicholson and Joy Laws.

description: Zeta Ori A is a hot star claimed to host a weak magnetic field, but no clear magnetic detection was obtained so far. In addition, it was recently shown to be a binary system composed of a O9.5I supergiant and a B1IV star. We aim at verifying the presence of a magnetic field in zeta Ori A, identifying to which of the two binary components it belongs (or whether both stars are magnetic), and characterizing the field.Very high signal-to-noise spectropolarimetric data were obtained with Narval at the Bernard Lyot Telescope (TBL) in France. Archival HEROS, FEROS and UVES spectroscopic data were also used. The data were first disentangled to separate the two components. We then analyzed them with the Least-Squares Deconvolution (LSD) technique to extract the magnetic information. We confirm that zeta Ori A is magnetic. We find that the supergiant component zeta Ori Aa is the magnetic component: Zeeman signatures are observed and rotational modulation of the longitudinal magnetic field is clearly detected with a period of 6.829 d. This is the only magnetic O supergiant known as of today. With an oblique dipole field model of the Stokes V profiles, we show that the polar field strength is ~ 140 G. Because the magnetic field is weak and the stellar wind is strong, zeta Ori Aa does not host a centrifugally supported magnetosphere. It may host a dynamical magnetosphere. Its companion zeta Ori Ab does not show any magnetic signature, with an upper limit on the undetected field of $\sim$ 300 G.

description: We apply the Sternberg et al. (2014) theoretical model to analyze HI and H2 observations in the Perseus molecular cloud. We constrain the physical properties of the HI shielding envelopes and the nature of the HI-to-H2 transitions. Our analysis (Bialy et al. 2015) implies that in addition to cold neutral gas (CNM), less dense thermally-unstable gas (UNM) significantly contributes to the shielding of the H2 cores in Perseus.

description: As the representative of the shock-capturing scheme, the Roe scheme fails to LES because important turbulent characteristics cannot be reproduced such as the famous k-5/3 spectral law owing to large numerical dissipation. In this paper, the Roe scheme is divided into five parts: , , , , and , which means basic upwind dissipation, pressure-difference-driven and velocity-difference-driven modification of the interface fluxes and pressure, respectively. Then, the role of each part on LES is investigated by homogeneous decaying turbulence. The results show that the parts , , and have little effect on LES. It is important especially for because it is necessary for computation stability. The large numerical dissipation is due to and , and each of them has much larger dissipation than SGS dissipation. According to these understanding, an improved all-speed LES-Roe scheme is proposed, which can give enough good LES results for even coarse grid resolution with usually adopted reconstruction.

Farhi, Phys. Rev. Lett. 88, 195301 (2002)]. We argue that these excitations are amplitude (Higgs) modes associated with fluctuations of the crystal order parameter within the unit cell. We present an analysis of the modes based on an effective Ginzburg-Landau model, classify them according to their symmetry properties, and compute their signature in INS experiments. In addition, we calculate the dynamical structure factor by means of an ab intio quantum Monte Carlo simulation and find a finite frequency excitation at zero relative momentum.

Video Against the Machine: Lens-Based Interventions in The Refugee Crisis
Creators: name: Houwen, Janna
Publisher: name: FKW // Zeitschrift für Geschlechterforschung und visuelle Kultur
Year: 2019

description: This article studies the military-industrial-surveillance complex at Europe’s borders as a machine that functions alongside and in response to the so-called refugee crisis, but that in itself is not in crisis at all. Following philosopher Maurizio Lazzarato’s definition of machinic systems, I conceptualize the machine as anapparatus that does not depend on techne perse, but as aseries of intertwined discursive/semiotic as well as non-discursive/material elements. When viewed through the lens of machine theory, the reduction of refugees to calculable formula and neatly arranged data packets cannot be seen as an isolated, purely discursive matter. It is part of a large machinic assemblage in which economic, judicial, social and technological components work together, producing material, immobilizing, de-subjectifying, as well as oftentimes lethal consequences for the human beings involved. Only after carefully studying the workings of this refugee machine, I argue, will it become possible to uncover possible modes of resistance against this controlling and objectifying system. In order to analyse the military-industrial-surveillance complex at Europe’s borders as a machinic system, I turn to two art-house documentary films which do exactly that. Nathalie Loubeyre’s Flow Mechanics (2016) and Morgan Knibbe’s Those Who Feel the Fire Burning(2014) will be read as forms of machine analysis that are very much in line with Lazzarato’s machine theory, as they map intertwining parts of a large refugee-controlling system at work in Southern European countries.

description: Motivated by the overwhelming evidence some type of quantum criticality underlies the power-law for the optical conductivity and $T-$linear resistivity in the cuprates, we demonstrate here how a scale-invariant or unparticle sector can lead to a unifying description of the observed scaling forms. We adopt the continuous mass formalism or multi band (flavor) formalism of the unparticle sector by letting various microscopic parameters be mass-dependent. In particular, we show that an effective mass that varies with the flavor index as well as a running band edge and lifetime capture the AC and DC transport phenomenology of the cuprates. A key consequence of the running mass is that the effective dynamical exponent can differ from the underlying bare critical exponent, thereby providing a mechanism for realizing the fractional values of the dynamical exponent required in a previous analysis\cite{ Hartnoll:2015sea}. We also predict that regardless of the bare dynamical exponent, $z$, a non-zero anomalous dimension for the current is required. Physically, the anomalous dimension arises because the charge depends on the flavor, mass or energy. The equivalent phenomenon in a $d+1$ gravitational construction is the running of the charge along the radial direction. The nature of the superconducting instability in the presence of scale invariant stuff shows that the transition temperature is not necessarily a monotonic function of the pairing interaction.

Escaping the Echo Chamber: Perspectives on Immigrant Representations in the Exhibition Space

Publisher: name: FKW // Zeitschrift für Geschlechterforschung und visuelle Kultur
Year: 2019

description: As a growing number of artists and curators have been using their works to express concern regarding the renewed discourse on migration in Europe, representations of migrant people have become more frequent in cultural institutions. The focus put on the figure of the migrant however raises some questions, notably concerning the ethics of representation. Indeed, while a strong focus is put on individual testimonies, the narrativisation of migrants’ experiences simultaneously runs the risk of invisibilising the broader contemporary border control systems, central to the functioning of migrations today. Works designed to produce empathetic reactions in the viewer through testimonies might paradoxically contribute to the silencing of migrants’ claims, while also failing to address the specific bureaucratic processes used by migratory control systems, at play in the making of what news media have been calling the ‘refugee crisis’ since 2015. In order to discuss and question current issues with the ways migrations tend to be represented, as well as possibilities for different representations, this paper will analyze and compare two artworks: Libia Castro and Olafur Olafsson’s audio sculpture Bosbolobosbocoand Lawrence Abu Hamdan’s Conflicted Phonemes, displayed at the 2016 exhibition Voices Outside the Echo Chamber: Questioning Myths, Facts and Framings of Migration, at the Framer Framed Gallery in Amsterdam in 2016. As the two works present radically different perspectives on the representation of migrations and migrant people, this article will propose a critical understanding of the different strategies they adopt, and how such strategies might impact social praxis.

Stuck Between Destinations: Reflections on Pejk Malinovski’s Virtual Reality Project 'This Room'
Creators: name: Nielsen, Sabine
Publisher: name: FKW // Zeitschrift für Geschlechterforschung und visuelle Kultur
Year: 2019

description: The article approaches the topic of the current ‘refugee crisis’ by discussing and analysing a specific case, namely a virtual reality installation produced in 2018 by the poet and sound artist Pejk Malinovski. This project, which is entitled This Room, is about refugees who arrived in Denmark in 2015 and their subsequent fates in refugee camps. It explores and exposes the harsh, stressful and often traumatizing living conditions of refugees. Besides, as a critical and political gesture, the project attempts to extend visibility and audibility to those who are currently consigned to life in camps. The article starts by presenting and reflecting on Malinovski’s project focusing specifically on the critical potential of its blurring of the boundaries between the documentary and the fictional. Subsequently, it analyses some of the effects it has produced, not least in its capacity as a site-specific version at Copenhagen Central Station, where it was mediated by refugees and volunteers from refugee organizations. The article argues that the project appears particularly relevant within its given contexts, such as in Copenhagen, because it is created by means of a participatory methodological approach. This Roomactually seeks to facilitate conflictual encounters, and does so at a series of different sites. Drawing on conflict theory and radical democracy theory, the article argues that artistic forms of critique necessitate the creation of agonistic contact zones in which negotiations can take place and counter-hegemonic publics can be created. It concludes by arguing that critical approach involves being partisan, i.e. taking a position which is dissensual, convincing and politically positioned. Thematically,This Roomhighlights the fact that mobility is often characterized by conflicts, negotiations, and the playing out of asymmetrical power relations. Furthermore,

Social justice within assessment/feedback practices in an EAP program
Creators: name: Al Dalati, Sara
Publisher: name: Lancaster University
Year: 2023

description: Assessment/feedback practices in higher education have been researched in a variety of contexts but the EAP (English for Academic Purposes) program has received little attention as the focus. This thesis seeks to trace the enactment of McArthur’s (2018) conceptual framework by analyzing data gained through insider-research on assessment/feedback practices within the Department of English Language and Literature in a Lebanese private higher education institution. Multiple collection methods, including two types of interviews, are used to explore teachers’ practices and students’ perceptions of assessment/feedback practices in the program. The analysis proceeds in 2 stages. Initially, we establish a theoretical grounding for the analysis of social justice embedding in an EAP program through assessment and feedback practices. We utilize McArthur’s (2018) framework to map how fairness is articulated and aligned, via the locally produced teachers’ assessment and feedback practices. Second, following Trowler and Cooper’s (2002) concept of Teaching and Learning Regimes (TLRs), we argue that there are limitations to the application of an ideal model of just assessment/feedback practices within the program. Findings reveal that McArthur’s framework (five understandings of trust, honesty, responsibility, forgiveness and responsiveness) can be interpreted in different ways, probably partially, and in order to realize assessment for social justice fully, each category needs to be filled out, not understood partially. This thesis contributes to literature as it discusses the practices that underpin socially-just changes within EAP programs through the examination of a case study of a higher education institution in Lebanon. The thesis also has a broader contribution and is of value to EAP and EAL (English as an additional language) using a richer framework around social justice and assessment. The findings potentially add to the understanding of McArthur’s (2018) work, particularly around how these concepts work in practice, and how the partial fulfillment of them falls short of their full potential.

description: Exploring the quantum behaviour of macroscopic objects provides an intriguing avenue to study the foundations of physics and to develop a suite of quantum-enhanced technologies. One prominent path of study is provided by quantum optomechanics which utilizes the tools of quantum optics to control the motion of macroscopic mechanical resonators. Despite excellent recent progress, the preparation of mechanical quantum superposition states remains outstanding due to weak coupling and thermal decoherence. Here we present a novel optomechanical scheme that significantly relaxes these requirements allowing the preparation of quantum superposition states of motion of a mechanical resonator by exploiting the nonlinearity of multi-photon quantum measurements. Our method is capable of generating non-classical mechanical states without the need for strong single photon coupling, is resilient against optical loss, and offers more favourable scaling against initial mechanical thermal occupation than existing schemes. Moreover, our approach allows the generation of larger superposition states by projecting the optical field onto NOON states. We experimentally demonstrate this multi-photon-counting technique on a mechanical thermal state in the classical limit and observe interference fringes in the mechanical position distribution that show phase superresolution. This opens a feasible route to explore and exploit quantum phenomena at a macroscopic scale.

To ease the comparison between the outputs of the stellar evolution computations and the observations, a dedicated tool was developed: the Syclist toolbox (Georgy et al. 2014). It allows to compute interpolated stellar models, isochrones, synthetic clusters, and to simulate the time-evolution of stellar populations.

Year: 2016

description: This thesis analyzes the differentiation of European Union accession momentum in Serbia and Macedonia. Although Serbia and Macedonia face similar domestic challenges in their EU accession sagas, Serbia has recently managed to outpace Macedonia, once a frontrunner in the process. The author assesses this divergence to stem from the institutional and political setup of EU enlargement, and stresses the importance for acceding countries to have a credible European perspective, and for the institutions of the EU to apply political conditionality consistently and constructively. The final section of the thesis suggests how the EU’s experience in Serbia could form the basis for a jumpstart of Macedonia’s EU accession bid.

description: We present and discuss the design details of an extensible, modular, open source software framework called EXOSIMS, which creates end-to-end simulations of space-based exoplanet imaging missions. We motivate the development and baseline implementation of the component parts of this software with models of the WFIRST-AFTA coronagraph, and present initial results of mission simulations for various iterations of the WFIRST-AFTA coronagraph design. We present and discuss two sets of simulations: The first compares the science yield of completely different instruments in the form of early competing coronagraph designs for WFIRST-AFTA. The second set of simulations evaluates the effects of different operating assumptions, specifically the assumed post-processing capabilities and telescope vibration levels. We discuss how these results can guide further instrument development and the expected evolution of science yields.

description: This project intends to present a modeling and simulation approach for voltage-source converter based HVDC (VSC-HVDC) Transmission System with various types of DC Links e.g., Monopolar, Bipolar, Homopolar. Power System Block (PSB) in MATLAB / Simulink helps creating detailed simulation models of high voltage direct current (HVDC) and its controllers. The basic theory and schematic structure of HVDC power transmission will be simulated in this project. The system reactions to steady state, the step of current reference, and the DC transmission line to ground fault are the parameters of interests for this model. The simulation can help achieving reasonably high exactness and precision for predicting various aspects and challenges of HVDC Transmission System.

description: Most black holes (BHs) will absorb a neutron star (NS) companion fully intact, without tidal disruption, suggesting the pair will remain dark to telescopes. Even without tidal disruption, electromagnetic luminosity is generated from the battery phase of the binary when the BH interacts with the NS magnetic field. Originally the luminosity was expected in high-energy X-rays or gamma-rays, however we conjecture that some of the battery power is emitted in the radio bandwidth. While the luminosity and timescale are suggestive of fast radio bursts (FRBs; millisecond-scale radio transients) NS--BH coalescence rates are too low to make these a primary FRB source. Instead, we propose the transients form a FRB sub-population, distinguishable by a double peak with a precursor. The rapid ramp-up in luminosity manifests as a precursor to the burst which is $20\%-80\%$ as luminous, given 0.5~ms timing resolution. The main burst is from the peak luminosity before merger. The post-merger burst follows from the NS magnetic field migration to the BH, causing a shock. NS--BH pairs are especially desirable for ground-based gravitational wave (GW) observatories since the pair might not otherwise be detected, with electromagnetic counterparts greatly augmenting the scientific leverage beyond the GW signal. Valuably, the electromagnetic signal can break degeneracies in the parameters encoded in the GW as well as probe the NS magnetic field strength, yielding insights into open problems in NS magnetic field decay.

Reputations for conflict and the formation of preferential trade agreements
Creators: name: Foster, Lee

description: The influence that reputations for hostility have on future interstate conflict and the formation of security alliances has been well-studied. By comparison, the influence of such reputations on relations outside the security realm has received relatively scant attention. This paper begins to close this gap, exploring how reputations for militarized conflict influence the formation and design of reciprocal trade arrangements. Specifically, I argue that an extra-dyadic reputation for hostility undermines the formation of Preferential Trade Agreements (PTAs) within the dyad, as a potential partner becomes skeptical of a state's willingness to adhere to agreement terms and to follow peaceful dispute settlement channels. Additionally, where PTAs are signed, reputations for hostility increase the likelihood of institutionalized, legalistic dispute settlement mechanisms (DSMs) being incorporated, as signatories attempt to shield themselves from future opportunistic behavior. Importantly, however, I argue that these reputational effects are only influential when states are not party to existing formal economic or security agreements. Logistic analyses of PTA signings and DSM design for the decade 1991-2000 provide empirical support for this argument. The results suggest that, regardless of actual intent, reputations for hostility can follow states around and undermine their ability to form cooperative relationships outside the security domain.

description: Dwarf spheroidal galaxies (dSphs) are mostly investigated in the Local Group. DSphs are difficult targets for observations because of their small size and very low surface brightness. Here we measure spectroscopic and photometric parameters of three candidates for isolated dSphs, KKH65=BTS23, KK180, and KK227, outside the Local Group. The galaxies are found to be of low metallicity and low velocity dispersion. They are among the lowest surface brightness objects in the Local Universe. According to the measured radial velocities, metallicities, and structural and photometric parameters, KKH65 and KK227 are representatives of the ultra-diffuse quenched galaxies. KKH65 and KK227 belong to the outer parts of the groups NGC3414 and NGC5371, respectively. KK180 is located in the Virgo cluster infall region.

description: Scientists have a single currency for productivity and impact: published articles. In an effort to map the global research landscape in microbiology, and to obviate the current lack of bibliometric analysis in the field, FEMS—the Federation of European Microbiological Societies—generated a dataset encompassing an exhaustive, worldwide list of microbiology studies for 2013–14, which further includes information as author affiliation, funding agency and number of citations. The manually curated database is useful in assessing the impact and regional productivity of microbiology research at different levels. Here, the data for microbiology research in South America are presented and discussed in detail. Based on the analysis, it emerged that despite great degrees of variation between number of published articles among the countries, a more levelled research productivity was observed when considering further dimensions like population size or number of research institutes. Normalised productivity and impact increase in countries with a ‘central research hub’, i.e. an institute or university producing a substantial portion of the national output (15% or more). From these observations, a possible strategy to increase impact and productivity in (microbiology) research for emerging countries is outlined.
Conditional Estimation in Two-stage Adaptive Designs

description: We consider conditional estimation in two-stage sample size adjustable designs and the following bias. More specifically, we consider a design which permits raising the sample size when interim results look rather promising, and, which keeps the originally planned sample size when results look very promising. The estimation procedures reported comprise the unconditional maximum likelihood, the conditionally unbiased Rao-Blackwell estimator, the conditional median unbiased estimator, and the conditional maximum likelihood with and without bias correction. We compare these estimators based on analytical results and by a simulation study. We show in a real clinical trial setting how they can be applied.

description: Supermassive black hole accretion and feedback play central role in the evolution of galaxies, groups, and clusters. I review how AGN feedback is tightly coupled with the formation of multiphase gas and the newly probed chaotic cold accretion (CCA). In a turbulent and heated atmosphere, cold clouds and kpc-scale filaments condense out of the plasma via thermal instability and rain toward the black hole. In the nucleus, the recurrent chaotic collisions between the cold clouds, filaments, and central torus promote angular momentum cancellation or mixing, boosting the accretion rate up to 100 times the Bondi rate. The rapid variability triggers powerful AGN outflows, which quench the cooling flow and star formation without destroying the cool core. The AGN heating stifles the formation of multiphase gas and accretion, the feedback subsides and the hot halo is allowed to cool again, restarting a new cycle. Ultimately, CCA creates a symbiotic link between the black hole and the whole host via a tight self-regulated feedback which preserves the gaseous halo in global thermal equilibrium throughout cosmic time.

description: Motivated by the current constraints on the epoch of reionisation from recent cosmic microwave background observations, ionising background measurements of star-forming galaxies, and low redshifts line-of-sight probes, we propose a new data-motivated parameterisation of the history of the average ionisation fraction. This parameterisation describes a flexible redshift-asymmetric reionisation process in two regimes that is capable of fitting all the current constraints.

"Ist das nicht schon Krieg?" 1968 und der Feminismus in Elfriede Jelineks frühen Essays und in 'Bukolit. Hörroman'

description: Since her early works Elfriede Jelinek has been heavily influenced by the political and cultural movements around 1968. Especially her views on Feminism, Criticism and Media Analysis reflect marxian and early poststructuralist approaches of that time. My article focusses on Jelineks early essays and on her first novel bukolit.hörroman, which had been finished in 1968, but wasn`t released until 1979. By drafting a short reconstruction of the younger austrian history and of the developments around 1968 my article tries to put Jelineks early works in a wider context. Her highly experimental novel bukolitand also her essayistic reflections can be read as indices of the artistic and critical possibilites after the cesura of 1968. In their parodistic style they also throw a critical glance on austria. They point out that 1968 there did not occure like it occured in other european countries and that it had a more anarchistic and even patriarchal undertone.

description: This review presents the new book by Nicola Settis, Chi è il sognatore? Guida alla visione di Twin Peaks 3 [Who is the Dreamer? A Guide to Watching Twin Peaks 3]. The young author, a scholar of cinema and media studies, offers a brilliant reading of director David Lynch's latest season of Twin Peaks, an enigmatic television series watched all around the world. Through a narrative and visual approach adapted to the contemporary, Twin Peaks 3, The Return constitutes a new device, a still unexplored object that produces endless questions and that never stops involving the spectator in reflective and sensorial mechanisms. “Who is the Dreamer?” investigates the symbols and internal connections within this open work which expresses both the director's personal vision and sensibilities, and the human boundary between dream and reality.
