description: We present a model of gamma-ray emission through neutral pion production and decay in two-temperature accretion flows around supermassive black holes. We refine previous studies of such a hadronic gamma-ray emission by taking into account (1) relativistic effects in the photon transfer and (2) absorption of gamma-ray photons in the radiation field of the flow. We use a fully general relativistic description of both the radiative and hydrodynamic processes, which allows us to study the dependence on the black hole spin. The spin value strongly affects the gamma-ray emissivity within ~10 gravitational radii. The central regions of flows with the total luminosities L < 0.001 of the Eddington luminosity are mostly transparent to photons with energies below 10 GeV, permitting investigation of the effects of space-time metric. For such L, an observational upper limit on the gamma-ray (0.1-10 GeV) to X-ray (2-10 keV) luminosity ratio of L_{0.1-10 GeV}/L_{2-10 keV} << 0.1 can rule out rapid rotation of the black hole; on the other hand, a measurement of L_{0.1-10 GeV}/L_{2-10 keV} ~ 0.1 cannot be regarded as the evidence of rapid rotation, as such a ratio can also result from a flat radial profile of gamma-ray emissivity (which would occur for nonthermal acceleration of protons in the whole body of the flow). At L > 0.01 of the Eddington luminosity, the gamma-ray emission from the innermost region is strongly absorbed and the observed gamma-rays do not carry information on the value of the black hole spin. We note that if the X-ray emission observed in Centaurus A comes from an accretion flow, the hadronic gamma-ray emission from the flow should contribute significantly to the MeV/GeV emission observed from the core of this object, unless it contains a slowly rotating black hole and protons in the flow are thermal.

description: Measurements of seismic wave travel times at the photosphere of the Sun have enabled inferences of its interior structure and dynamics. In interpreting these measurements, the simplifying assumption that waves propagate through a temporally stationary medium is almost universally invoked. However, the Sun is in a constant state of evolution, on a broad range of spatio-temporal scales. At the zero wavelength limit, i.e., when the wavelength is much shorter than the scale over which the medium varies, the WKBJ (ray) approximation may be applied. Here, we address the other asymptotic end of the spectrum, the infinite wavelength limit, using the technique of homogenization. We apply homogenization to scenarios where waves are propagating through rapidly varying media (spatially and temporally), and derive effective models for the media. One consequence is that a scalar sound speed becomes a tensorial wavespeed in the effective model and anisotropies can be induced depending on the nature of the perturbation. The second term in this asymptotic two-scale expansion, the so-called corrector, contains contributions due to higher-order scattering, leading to the decoherence of the wavefield. This decoherence may be causally linked to the observed wave attenuation in the Sun. Although the examples we consider here consist of periodic arrays of perturbations to the background, homogenization may be extended to ergodic and stationary random media. This method may have broad implications for the manner in which we interpret seismic measurements in the Sun and for modeling the effects of granulation on the scattering of waves and distortion of normal-mode eigenfunctions.

description: Elastomeric bonded permeable revetments, also called PBA (Polyurethane bonded aggregate) revetments, are highly porous structures made of mineral aggregates (e.g. crushed stones) which are durably and elastically bonded by polyurethane (PU). Despite their numerous advantages as compared to conventional revetments and the large experience available from more than 25 pilot projects, physically-based design formulae to predict their hydraulic performance, wave loading and response are still lacking. Therefore, the present study aims at improving the understanding of the processes involved in the interaction between wave, revetment and foundation, based on large-scale model tests performed in the Coastal Research Centre (FZK), Hannover/Germany, and to provide prediction formulae/diagrams. This paper is focused on the prediction of the hydraulic performance (wave reflection, wave runup and run-down) and the response of the sand core (pore pressure) beneath the revetment for a wide range of wave conditions, including the analysis of an observed failure due to transient soil liquefaction.

description: We apply a recently proposed theoretical concept and numerical approach to obtain time delays in extreme ultraviolet (XUV) photoionization of an electron in a short- or long-range potential. The results of our numerical simulations on a space-time grid are compared to those for the well-known Wigner-Smith time delay and different methods to obtain the latter time delay are reviewed. We further use our numerical method to analyze the effect of a near-infrared streaking field on the time delay obtained in the numerical simulations.

description: Due to insufficient insights about the scour development around the STRABAG gravity foundation, the Franzius-Institute conducted small- and large-scale physical model tests in wave flumes on a scale of 1:50 and 1:17 in order to investigate the wave-induced scouring phenomena around the foundation and to design a scour protection system. The tests on scour development without a scour protection system show that the main areas which are vulnerable to scour are the contact areas of the foundation. Furthermore, the experiments show that a scour protection system is necessary for the given and investigated wave boundary conditions; the performance of the selected protection system using geotextile sand containers is verified. Additional numerical simulations indicate an amplification of the resulting flow around the foundation under combined loads (waves and current), but without significant change of the flow pattern.

description: The administration of a Web directory content and associated structure is a labor intensive task performed by human domain experts. Because of that there always exists a realistic risk of the structure becoming unbalanced, uneven and difficult to use to all except for a few users proficient in a particular Web directory. These problems emphasize the importance of generic and objective measures of Web directories structure quality. In this paper we demonstrate how to formally merge Web directories into the Semantic Web vision. We introduce a set of objective criterions for evaluation of a Web directory's structure quality. Some criteria functions are based on heuristics while others require the application of ontologies.

description: Direct geo-referencing is an efficient methodology for the fast acquisition of 3D spatial data. It requires the fusion of spatial data acquisition sensors with navigation sensors, such as Global Navigation Satellite System (GNSS) receivers. In this contribution, we consider an integrated GNSS navigation system to provide estimates of the position and attitude (orientation) of a 3D laser scanner. The proposed multi-sensor system (MSS) consists of multiple GNSS antennas rigidly mounted on the frame of a rotating laser scanner and a reference GNSS station with known coordinates. Precise GNSS navigation requires the resolution of the carrier phase ambiguities. The proposed method uses the multivariate constrained integer least-squares (MC-LAMBDA) method for the estimation of rotating frame ambiguities and attitude angles. MC-LAMBDA makes use of the known antenna geometry to strengthen the underlying attitude model and, hence, to enhance the reliability of rotating frame ambiguity resolution and attitude determination. The reliable estimation of rotating frame ambiguities is consequently utilized to enhance the relative positioning of the rotating frame with respect to the reference station. This integrated (array-aided) method improves ambiguity resolution, as well as positioning accuracy between the rotating frame and the reference station. Numerical analyses of GNSS data from a real-data campaign confirm the improved performance of the proposed method over the existing method. In particular, the integrated method yields reliable ambiguity resolution and reduces position standard deviation by a factor of about 0:8, matching the theoretical gain of ?3/4 for two antennas on the rotating frame and a single antenna at the reference station.

description: Cognitive radio (CR) is to detect the presence of primary users (PUs) reliably in order to reduce the interference to licensed communications. Genetic algorithms (GAs) are well suited for CR optimization problems to increase efficiency of bandwidth utilization by manipulating its unused portions of the apparent spectrum. In this paper, a binary genetic algorithm (BGA)-based soft fusion (SF) scheme for cooperative spectrum sensing in cognitive radio network is proposed to improve detection performance and bandwidth utilization. The BGA-based optimization method is implemented at the fusion centre of a linear SF scheme to optimize the weighting coefficients vector to maximize global probability of detection performance. Simulation results and analyses confirm that the proposed scheme meets real time requirements of cognitive radio spectrum sensing and it outperforms conventional natural deflection coefficient- (NDC-), modified deflection coefficient- (MDC-), maximal ratio combining- (MRC-) and equal gain combining- (EGC-) based SDF schemes as well as the OR-rule based hard decision fusion (HDF). The propose BGA scheme also converges fast and achieves the optimum performance, which means that BGA-based method is efficient and quite stable also.

description: This study is based on the data obtained from tests carried out in the Large Wave Flume (Grosser Wellenkanal (GWK)) in Hannover in the frame of a joint research project of Ghent University (Belgium) and Forschungszentrum Küste (FZK, Germany). The goal of the research project is to determine the wave induced loads on vertical storm walls located at the end of overtopped dike, which are designed to protect coastal cities from overtopping and floods. The loads resulting from waves overtopping the dike and impacting the vertical wall as a bore are measured by means of both force and pressure sensors. This paper describes the results of pressure and force records at the vertical wall, including a comparative analysis of the overall forces obtained by pressure integration and force sensors for two different wall setups: Fully blocked wall and partially blocked wall.

description: The spatial assessment of short time-step precipitation is a challenging task. Low density of observation networks, as well as the bias in radar rainfall estimation motivated the new idea of exploiting cars as moving rain gauges with windshield wipers or optical sensors as measurement devices. In a preliminary study, this idea has been tested with computer experiments (Haberlandt and Sester, 2010). The results have shown that a high number of possibly inaccurate measurement devices (moving cars) provide more reliable areal rainfall estimations than a lower number of precise measurement devices (stationary gauges). Instead of assuming a relationship between wiper frequency (W) and rainfall intensity (R) with an arbitrary error, the main objective of this study is to derive valid W-R relationships between sensor readings and rainfall intensity by laboratory experiments. Sensor readings involve the wiper speed, as well as optical sensors which can be placed on cars and are usually made for automating wiper activities. A rain simulator with the capability of producing a wide range of rainfall intensities is designed and constructed. The wiper speed and two optical sensors are used in the laboratory to measure rainfall intensities, and compare it with tipping bucket readings as reference. Furthermore, the effect of the car speed on the estimation of rainfall using a car speed simulator device is investigated. The results show that the sensor readings, which are observed from manual wiper speed adjustment according to the front visibility, can be considered as a strong indicator for rainfall intensity, while the automatic wiper adjustment show weaker performance. Also the sensor readings from optical sensors showed promising results toward measuring rainfall rate. It is observed that the car speed has a significant effect on the rainfall measurement. This effect is highly dependent on the rain type as well as the windshield angle. © 2013 Authjor(s).
Functional methods underlying classical mechanics, relativity and quantum theory

description: The paper investigates the physical content of a recently proposed mathematical framework that unifies the standard formalisms of classical mechanics, relativity and quantum theory. In the framework states of a classical particle are identified with Dirac delta functions. The classical space is "made" of these functions and becomes a submanifold in a Hilbert space of states of the particle. The resulting embedding of the classical space into the space of states is highly non-trivial and accounts for numerous deep relations between classical and quantum physics and relativity. One of the most striking results is the proof that the normal probability distribution of position of a macroscopic particle (equivalently, position of the corresponding delta state within the classical space submanifold) yields the Born rule for transitions between arbitrary quantum states.

description: With the growing number of digitally available collections consisting of images depicting relevant objects from the past in relation with descriptive annotations, the need for suitable information retrieval techniques is becoming increasingly important to support historians in their work. In this context, we address the problem of image retrieval for searching records in a database of silk fabrics. The descriptors, used as an index to the database, are learned by a convolutional neural network, exploiting the available annotations to automatically generate training data. Descriptor learning is combined with auxiliary classification loss with the aim of supporting the clustering in the descriptor space with respect to the properties of the depicted silk objects, such as the place or time of origin. We evaluate our approach on a dataset of fabric images in a kNN-classification, showing promising results with respect to the ability of the descriptors to represent semantic properties of silk fabrics; integrating the auxiliary loss improves the overall accuracy by 2.7% and the average F1 score by 5.6%. It can be observed that the largest improvements can be obtained for variables with imbalanced class distributions. An evaluation on the WikiArt dataset demonstrates the transferability of our approach to other digital collections

description: The Lipkin-Meshkov-Glick (LMG) model has a Schwinger boson realization in terms of a two-level boson pairing Hamiltonian. Through this realization, it has been shown that the LMG model is a particular case of the SU (1, 1) Richardson-Gaudin (RG) integrable models. We exploit the exact solvability of the model tostudy the behavior of the spectral parameters (pairons) that completely determine the wave function in the different phases, and across the phase transitions. Based on the relation between the Richardson equations and the Lamé differential equations we develop a method to obtain numerically the pairons. The dynamics of pairons in the ground and excited states provides new insights into the first, second and third order phase transitions, as well as into the crossings taking place in the LMG spectrum.

Claiming Space and Contesting Gendered Refugeehood in Exile: Issues and Factors of Rohingya Refugee Women’s Civic Engagement in Diaspora

Publisher: name: International Quarterly for Asian Studies
Year: 2022

description: This article examines the emerging political and social mobilisation of Rohingya women activists in connection with the forced displacement of nearly a million Rohingya from the Rakhine state of Myanmar in August 2017. In exile, a promising number of Rohingya women have become actively engaged in social and political domains that have been historically male-dominated. The findings reveal how the internationalisation and the considerable global attention to the Rohingya refugee crisis have provided the space to navigate traditional gender roles and created an opportunity for Rohingya women to become important civic actors in this relatively nascent diaspora. Varying levels of education, age, technical and linguistic skills, along with diverse opportunities offered by the host countries, impact the (in)ability of Rohingya refugee women to play their part in diaspora activism.

Ecological Civilisation: A Historical Perspective on Environmental Policy Narratives in China
Creators: name: Westman, Linda

Publisher: name: International Quarterly for Asian Studies
Year: 2022

description: This paper engages with China’s currently most prominent environmental policy concept: ecological civilisation. As this concept is becoming a cornerstone of China’s strategy of socialist modernisation, we examine whether and how the term can enable ecological protection in China and beyond. We argue that ecological civilisation, while a recently emerged discourse, builds on established environmental governance practices in China that shape its manifestation in political action. To illustrate this argument, we explain how two philosophical principles central to ecological civilisation discourse, “holism” and “harmony”, have been expressed in environmental political practice in Communist China. Building on this analysis, we suggest that ecological civilisation discourse may have a profound impact in certain policy domains (e.g., resource conservation and ecologi­cal conservation redlines), but limited transformative capacity in others (e.g., environmental litigation and resource extraction).

description: Ensemble forecasts aim at framing the uncertainties of the potential future development of the hydro-meteorological situation. A probabilistic evaluation can be used to communicate forecast uncertainty to decision makers. Here an operational system for ensemble based flood forecasting is presented, which combines forecasts from the European COSMO-LEPS, SRNWP-PEPS and COSMO-DE prediction systems. A multi-model lagged average super-ensemble is generated by recombining members from different runs of these meteorological forecast systems. A subset of the super-ensemble is selected based on a priori model weights, which are obtained from ensemble calibration. Flood forecasts are simulated by the conceptual rainfall-runoff-model ArcEGMO. Parameter uncertainty of the model is represented by a parameter ensemble, which is a priori generated from a comprehensive uncertainty analysis during model calibration. The use of a computationally efficient hydrological model within a flood management system allows us to compute the hydro-meteorological model chain for all members of the sub-ensemble. The model chain is not re-computed before new ensemble forecasts are available, but the probabilistic assessment of the output is updated when new information from deterministic short range forecasts or from assimilation of measured data becomes available. For hydraulic modelling, with the desired result of a probabilistic inundation map with high spatial resolution, a replacement model can help to overcome computational limitations. A prototype of the developed framework has been applied for a case study in the Mulde river basin. However these techniques, in particular the probabilistic assessment and the derivation of decision rules are still in their infancy. Further research is necessary and promising.

description: Three online thematic workshops took place in the Spring of 2023. These are the proceedings from the 3rd workshop, organised by WG5 and PlasticsFatE on April 21st 2023, focusing on data and information gaps and titled: 'A practice-based analysis of data needs, availability, reuse and gaps for MNP-risk related tools'. An analysis of the risk associated with micro and nanoplastics (MNP) includes a number of aspects that should be considered. In addition to information about the material itself, its applications and its life cycle, it is necessary to analyze the hazard and exposure to enable a risk characterization. Different methods can be used for each part of the risk assessment process. For example, Integrated Approaches for Testing and Assessment (IATAs) for hazard assessment or Material Flow Analysis (MFA) to provide a basis for calculating Predicted Environmental Concentrations (PECs) to estimate exposure. A number of methods are being applied or newly developed in ongoing projects aimed at improving our understanding of the health effects of MNPs. Depending on which part of the risk assessment they belong to, they may require different kinds of input information. To this end, contributions from the CUSP projects and the EU project PAPILLONS on plastic in agricultural production provided an overview of their approaches along the following questions:
 1. what methods are you developing (or applying) for risk analysis/risk assessment?
 2. what type of data do you need?
 3. are there any problems in collecting these data?
 4. what sources do you use to obtain the data?
 In a structured discussion, we tried to determine if the methods are compatible with the available data or if there are gaps or even problems with the format or quality of the data. A second part of the discussion was devoted to ideas on how to solve the problems
 identified. Sometimes the data exist somewhere but are hard to find, not harmonized, and not centralized in a common database. In addition, the quality of the studies in which the data were generated also plays a role. These issues were addressed in two presentations in the second part of the workshop. In a final discussion we tried to concretize the further steps, taking into account the input from the second part of the workshop.

description: We investigate differences and similarities between fundamental fermions and adjoint fermions in SU(N) gauge theories. The gauge theory with fundamental fermions possesses ZN symmetry only in the limit of infinite fermion mass, whereas the gauge theory with adjoint fermions does have the symmetry for any fermion mass. The flavor-dependent twisted boundary condition (FTBC) is then imposed on fundamental fermions so that the theory with fundamental fermions can possess ZN symmetry for any fermion mass. We show similarities between FTBC fundamental fermions and adjoint fermions, using the Polyakov-loop extended Nambu--Jona-Lasinio (PNJL) model. In the mean-field level, the PNJL model with FTBC fundamental fermions has dynamics similar to the PNJL model with adjoint fermions for the confinement/deconfinement transition related to ZN symmetry. The chiral property is somewhat different between the two models, but there is a simple relation between chiral condensates in the two models. As an interesting high-energy phenomenon, a possibility of the gauge symmetry breaking is studied for FTBC fundamental fermions.

description: The process of browsing Search Results is one of the major problems with traditional Web search engines for English, European, and any other languages generally, and for Arabic Language particularly. This process is absolutely time consuming and the browsing style seems to be unattractive. Organizing Web search results into clusters facilitates users quick browsing through search results. Traditional clustering techniques (data-centric clustering algorithms) are inadequate since they don't generate clusters with highly readable names or cluster labels. To solve this problem, Description-centric algorithms such as Suffix Tree Clustering (STC) algorithm have been introduced and used successfully and extensively with different adapted versions for English, European, and Chinese Languages. However, till the day of writing this paper, in our knowledge, STC algorithm has been never applied for Arabic Web Snippets Search Results Clustering.In this paper, we propose first, to study how STC can be applied for Arabic Language? We then illustrate by example that is impossible to apply STC after Arabic Snippets pre-processing (stem or root extraction) because the Merging process yields many redundant clusters. Secondly, to overcome this problem, we propose to integrate STC in a new scheme taking into a count the Arabic language properties in order to get the web more and more adapted to Arabic users. The proposed approach automatically clusters the web search results into high quality, and high significant clusters labels. The obtained clusters not only are coherent, but also can convey the contents to the users concisely and accurately. Therefore the Arabic users can decide at a glance whether the contents of a cluster are of interest.....
Models of soft rotators and the theory of a harmonic rotator

description: The states of a planar oscillator are separated to a vibrational mode, containing a zero-point energy, and a rotational mode without the zero-point energy, but having a conserved angular momentum. On the basis of the analysis of properties of models of rigid and semirigid rotators, the theory of soft rotators is formulated where the harmonic attractive force is balanced only by the centrifugal force. As examples a Coulomb rotator (the Bohr model) and a magneto-harmonic rotator (the Fock-Landau levels) are considered. Disappearance of the radial speed in the model of a magneto-harmonic rotator is taken as a defining property of a pure rotational motion in the harmonic potential. After the exception of energies of the magnetic and spin decompositions, specific to magnetic fields, one turns to a simple and general model of a planar harmonic rotator (circular oscillator without radial speed) where kinetic energy is reduced to the purely rotational energy. Energy levels of the harmonic rotator have the same frequency and are twice degenerate, the energy spectrum is equidistant. In the ground state there is no zero-point energy from rotational modes, and the zero-point energy of vibrational modes can be compensated by spin effects or symmetries of the system. In this case the operators of observables vanish the ground state, i.e. are "strongly" normally ordered. In a chain of harmonic rotators collective rotations around a common axis lead to transverse waves, at quantization of which there appear quasi-particles and holes carrying an angular momentum. In the chain SU(2) appears as a group of symmetry of a rotator.

description: The RESISTIRÉ project examines inequalities using a gender+ approach, which includes the application of a gender perspective in the quantitative and qualitative analyses of other socioeconomic differences. The European datasets that were used over the course of three research cycles of the project provided an opportunity to explore relevant indicators and the unequal experience of different groups during the pandemic. While our data analysis was able to identify and highlight some existing and worsening inequalities, it was often challenging to undertake an intersectional, gender+ approach because of a lack of more accurately representative European-level data.

description: Hochfeste Vergussmörtel werden häufig in Verbindungen der Gründungsstruktur von Windenergieanlagen eingesetzt, wo sie hochzyklischen Beanspruchungen ausgesetzt sind. Neuere Untersuchungsergebnisse deuten auf ein unterschiedliches Ermüdungsverhalten von Vergussmörteln im Vergleich zu hochfestem Beton hin. Im Rahmen dieses Beitrags wird das Ermüdungsverhalten von unterschiedlich fein zusammengesetzten Vergussmörteln und einem hochfesten Beton als Referenzbeton verglichen. Anhand der Bruchlastwechselzahlen konnte kein drastischer Unterschied im Ermüdungsverhalten zwischen Vergussmörteln und dem Referenzbeton erkannt werden. Es konnte jedoch gezeigt werden, dass die Erwärmungsrate von der Mörtelzusammensetzung und von der bezogenen Oberspannung beeinflusst wird. Eine Korrelation zwischen einer höheren Erwärmungsrate und einer größeren Dehnungszunahme der Unterdehnung in Phase II konnte erkannt werden.
description: High-strength grouts are commonly used in the connection of wind turbines, where they are exposed to high cyclic loading. The lastest scientific results indicate difference between the fatigue behavior of high-strength grouts compared to high-strength concrete. Therefore, the fatigue behaviour of high-strength grouts with different fineness of composition and high-strength concrete as reference was investigated in this contribution. No drastic difference in the fatigue behaviour between high-strength grouts and the reference concrete can be detected on the basis of the numbers of cycles to failure. It could be shown that the heating rate is influenced by the concrete composition and by the maximum stress level. A correlation between a higher heating rate and a larger increase in strain at the minimum stress level could be detected.

description: Temporal variations of atmospheric density distribution induce changes in the gravitational air mass attraction at a specific observation site. Additionally, the load of the atmospheric masses deforms the Earth’s crust and the sea surface. Variations in the local gravity acceleration and atmospheric pressure are known to be corrected with an admittance of about 3 nm/s2 per hPa as a standard factor, which is in accordance with the IAG Resolution No. 9, 1983. A more accurate admittance factor for a gravity station is varying with time and depends on the total global mass distribution within the atmosphere. The Institut für Erdmessung (IfE) performed absolute gravity observations in the Fennoscandian land uplift area nearly every year from 2003 to 2008. The objective is to ensure a reduction with 3 nm/s2 accuracy. Therefore, atmospheric gravity changes are modeled using globally distributed ECMWF data. The attraction effect from the local zone around the gravity station is calculated with ECMWF 3D weather data describing different pressure levels up to a height of 50 km. To model the regional and global attraction, and all deformation components the Green’s functions method and surface ECMWF 2D weather data are used. For the annually performed absolute gravimetry determinations, this approach improved the reductions by 8 nm/s2 (-19 nm/s2 to +4 nm/s2). The gravity modeling was verified using superconducting gravimeter data at station Membach inBelgiumimproving the residuals by about 15%.
The Stranger and the Periphery

description: Within my work, I have been interested in exploring, through detailed observation of, and collecting artifacts from, my surroundings, the effect that place and memory have on humans and their environment. I explore the various invisible stories impacted by specific places and events, and those things that exist but do not show themselves directly. Recently, using ‘placeness’—which gets its meaning from recognition and experience—as a foundation, my interest has moved towards people and places separated from their pasts due to migration and movement, disconnection and destruction, and thus that do not have this sense of ‘placeness’. While on my doctoral programme, I went beyond simply composing my work from photographs I had taken myself, to researching and collecting a variety of materials. This was my own way of reaching times and places unreachable to me, However, having worked with the medium of photography, I came to realise the limits and difficulties of working outside the current time and beyond places I could approach directly. I believe that my work is one way of telling a story, and is also a process of training myself to communicate with and learn about the world. I am interested in the concerns of contemporary society, as well as the connections I hold with the world, continually questioning what meaning my work has in the present, and what meaning it will come to hold as time passes. Within this process, the present report provided me the opportunity to theorise around the fundamental ‘anxiety’ I felt as a stranger living in a foreign country and to examine my experience from an objective point of view. I searched out information on theories surrounding all types of societal outsiders and marginal men, as well as boundary areas; I was able to reflect on their definitions, and understand that the anxiety I felt was not peculiar to me. The emotional anxiety of the foreigner, and the personal thoughts I could not express, and to which nobody would listen, went beyond a language-based problem to the structural level. The sociological theories and humanities-based definitions I researched for my Doctoral report gave me a more comprehensive understanding of these emotions.
