description: In this article, one defines two models of adaptive systems: the meta-dynamical adaptive system using the notion of Kalman dynamical systems and the adaptive differential equations using the notion of variable dimension spaces. This concept of variable dimension spaces relates the notion of spaces to the notion of dimensions. First, a computational model of the Douady's Rabbit fractal is obtained by using the meta-dynamical adaptive system concept. Then, we focus on a defense-attack biological model described by our two formalisms.
«Die Beziehungen geben mir einfach zu denken […] sind einfach in dem Moment und dann ist wieder fertig» (B5, Z245): Eine qualitative Untersuchung zum Teilhabeerleben von Menschen mit einer psychischen Beeinträchtigung mit Blick auf ihre sozialen Beziehungen im Alltag

description: Teilhabechancen von Menschen mit Beeinträchtigung werden seit dem Übereinkommen über die Rechte von Menschen mit Behinderungen (UN-BRK) in Wissenschaft, Politik und Praxis diskutiert. Mit Blick auf die Lebenssituation von Menschen mit einer psychischen Beeinträchtigung erstaunt, dass bislang qualitative Studien fehlen, welche sich für das Teilhabeerleben aus Sicht von diesem Personenkreis interessieren und dabei den Fokus auf Beziehungen aus ihrem Alltag setzen - zumal soziale Beziehungen als Schlüsselfaktoren für Teilhabe gelten. Deshalb fragt die vorliegende Arbeit danach, welche Beziehungsformen von Menschen mit einer psychischen Beeinträchtigung vor dem Hintergrund der UN-BRK als teilhabefördernd oder -hindernd erlebt werden. Dazu wurden im Rahmen einer qualitativen Untersuchung sieben problemzentrierte Interviews durchgeführt und mit der Methode der inhaltlich-strukturierenden qualitativen Inhaltsanalyse nach Mayring ausgewertet. Die Ergebnisse zeigen, dass neben Beziehungen zu Fachpersonen sowie zu Kolleginnen und Kollegen zwar auch Beziehungen zu Familienangehörigen als stützend erlebt werden, gleichzeitig letztere jedoch häufig konfliktbelastet sind und auf problematische biographische Verläufe hinweisen. Aus der Untersuchung wird zudem ersichtlich, dass Menschen mit einer psychischen Beeinträchtigung tragfähige Freundschaften vermissen und im Rahmen ihrer sozialen Beziehungen und Sozialkontakte immer noch Diskriminierung und Stigmatisierung erfahren. Es kann der Schluss gezogen werden, dass die (unsichtbaren) Teilhabebarrieren trotz gesetzlicher Grundlage nach wie vor bestehen. Die Soziale Arbeit hat einerseits die Möglichkeit, Betroffene mit einem professionellen Bindungsangebot zu stärken, andererseits als Menschenrechtsprofession Begegnung auf Augenhöhe zu fördern. Dies bietet zugleich die Chance, eigene professionelle Grundhaltungen gegenüber Menschen mit einer psychischen Beeinträchtigung zu überprüfen.

description: We calculate the carrier density dependent ground state properties of graphene in the presence of random charged impurities in the substrate taking into account disorder and interaction effects non-perturbatively on an equal footing in a self-consistent theoretical formalism. We provide detailed quantitative results on the dependence of the disorder-induced spatially inhomogeneous two-dimensional carrier density distribution on the external gate bias, the impurity density, and the impurity location. We find that the interplay between disorder and interaction is strong, particularly at lower impurity densities. We show that for the currently available typical graphene samples, inhomogeneity dominates graphene physics at low ($\lesssim 10^{12}$ cm$^{-2}$) carrier density with the density fluctuations becoming larger than the average density.

description: Asymptotic giant branch (AGB) stars are considered to be among the most significant contributors to the fluorine budget in our Galaxy. While at close-to-solar metallicity observations and theory agree, at lower metallicities stellar models overestimate the fluorine production with respect to heavy elements. We present ${}^{19}$F nucleosynthesis results for a set of AGB models with different masses and metallicities in which magnetic buoyancy acts as the driving process for the formation of the ${}^{13}$C neutron source (the so-called ${}^{13}$C pocket). We find that ${}^{19}$F is mainly produced as a result of nucleosynthesis involving secondary ${}^{14}$N during convective thermal pulses, with a negligible contribution from the ${}^{14}$N present in the ${}^{13}$C pocket region. A large ${}^{19}$F production is thus prevented, resulting in lower fluorine surface abundances. As a consequence, AGB stellar models with magnetic-buoyancy-induced mixing at the base of the convective envelope well agree with available fluorine spectroscopic measurements at both low and close-to-solar metallicity.

Προς τούτο, εντοπίστηκαν , συγκεντρώθηκαν, καταγράφηκαν και σχολιάστηκαν όλες οι παραστάσεις του βίου του από τη γέννηση ως το θάνατο της Σάρρας και το δικό του. Προσέτι, σκηνές ιστορικά τεκμηριωμένες, όπως η Φιλοξενία και η Θυσία του Αβραάμ, οι οποίες, εξαιτίας της τυπολογικής τους σχέσης με γεγονότα της Καινής Διαθήκης χρησιμοποιούνται στην εκκλησιαστική τέχνη αποσπασμένες από τον κύκλο, μελετώνται σε ξεχωριστά κεφάλαια. Για την πληρέστερη παρουσίαση των εικονογραφικών παραστάσεων του πατριάρχη, στη μελέτη προστέθηκαν ακόμη δύο κεφάλαια που αφορούν στον κόλπο του Αβραάμ και στις μεμονωμένες απεικονίσεις του (γενεαλογικές σειρές Χριστού, Ρίζα Zεσσαί κτλ). Αυτό που επιδιώκει και τελικά καταφέρνει να παρουσιάσει η παρούσα εργασία είναι το πρόσωπο και η ιστορία του πατριάρχου Αβραάμ, καθώς και το ρόλο του στο έργο της Θείας Οικονομίας με σκοπό να αιτιολογηθεί η ενσωμάτωση σκηνών του βίου στα εικονογραφικά προγράμματα των ναών, η απεικόνισή του σε ιερατικά άμφια και σκεύη, η ιστορησή του σε φορητές εικόνες και η παράστασή του σε μικρογραφίες χειρογράφων
description: This PhD thesis is the first attempt of iconographical approach of the "iconographical cycle of the patriarch Abraham", including a full scale of his depictions in art as well as of his life-scenes. Therefore, there had been traced, gathered, recorded and commented all the represantions of his life, from his own birth until his death and Sara's. Furthermore, historically argued scenes, such as Hospitality and Sacrifice of Jsaac, which are used in christian art extracted from the cycle, because of their typological relationship(prefigurations) with New Testament facts, are being studied in separate capitals. For a better approach of the patriarch Abraham's iconography, there have been added two more capitals concerning the iconography of Abraham's Bossoms and his individual depictions(geneology of Christ, Tree of Jessai etc). Finally, the main goal of this PhD thesis is the representation of patriarch Abraham's personality emphasizing in his role at the Divine economy. The purpose is the justification of the presence of the scenes from his life among the iconographical of churches, his depictions on textiles and bowls, as well as icons and miniatures

description: Pedagogical introduction into the problem of the mathematical description of the quantum correlation (entanglement) of composite quantum systems is represented. The notion is substantiated about the fact that the conventional algorithm of the reduction of von Neumann in the description of the dynamics of the observed subsyatem is not universal and corresponds only to the case of maximum macroscopicity of the unobservable subsystem. Is clearly shown the sense of the algorithm of the correlated reduction proposed, which minimally changes the entropy of composite system.

description: Designing robust frameworks for precise prediction of future prices of stocks has always been considered a very challenging research problem. The advocates of the classical efficient market hypothesis affirm that it is impossible to accurately predict the future prices in an efficiently operating market due to the stochastic nature of the stock price variables. However, numerous propositions exist in the literature with varying degrees of sophistication and complexity that illustrate how algorithms and models can be designed for making efficient, accurate, and robust predictions of stock prices. We present a gamut of ten deep learning models of regression for precise and robust prediction of the future prices of the stock of a critical company in the auto sector of India. Using a very granular stock price collected at 5 minutes intervals, we train the models based on the records from 31st Dec, 2012 to 27th Dec, 2013. The testing of the models is done using records from 30th Dec, 2013 to 9th Jan 2015. We explain the design principles of the models and analyze the results of their performance based on accuracy in forecasting and speed of execution.

description: In scanning probe microscopy laser interferometers are usually used for measuring the position of the probe tip with a metrological traceability. As the most of the AFM setups are designed to work under standard atmospheric conditions the changes of the refractive index of air have an influence to measured values of the length with 1.0e-4 relatively. In order to achieve better accuracies the refractive index of air has to be monitored continuously and its instantaneous value has to be used for compensating the lengths measured by all of the interferometric axes. In the presented work we developed a new concept of an electronic unit which is able to monitor the refractive index of air on basis of measurement of ambient atmospheric conditions: temperature, humidity, pressure of the air and the CO2 concentration. The data processing is based on Ciddor equation for calculating the refractive index of air. The important advantage of the unit is a very low power consumption of the electronics so the unit causes only negligible temperature effects to the measured environment. The accuracy of the indirect measuring method employed by the unit was verified. We tested the accuracy in comparison with a direct method of measuring refractive index of air based on an evacuatable cell placed at the measuring arm of a laser interferometer. An experimental setup used for verification is presented together with a set of measurements describing the performance. The resulting accuracy of the electronic unit falls to the 4.1e-7 relatively.

description: Digital media have facilitated the growth of citizen self-initiated and self-directed protest campaigns that often lack an authoritative central organizer. One challenge facing such protest campaigns is how internal disagreements about key issues can be resolved or contained. To what extent can movement participants handle disagreements constructively through digital communication? This article addresses this question through a case study of online discussions surrounding the political consumerism campaign during the Anti-Extradition Law Amendment Bill Movement in Hong Kong. Qualitative content analysis illustrates the range of disagreements that could arise in a self-directed political consumerism campaign and uncovers the various types of engaging and disengaging communications that people practiced. Quantitative content analysis shows that disengaging communications were more common, yet people were more responsive to engaging communications. The latter was more obvious as the campaign proceeded. Implications of the findings on the capability of decentralized protests to resolve internal differences are discussed.

description: This article aims to explain the importance of ‘I’ in Andrei Belyi’s work. Data is collected and analysed from a passage of his manuscript A Crisis of Thinking. It is shown that the author has a strong intention to use this first personal pronoun in its singular form in his text. It also is exemplified that Belyi’s ‘I’ is not a symbol of self-admiration, but evidence of his deep interests in Indian philosophical systems, in particular Vedanta and Buddhism. Further details are provided which justify Belyi’s appropriation of several Indian truths in order to solve the contemporary crisis of thinking. By pointing to the unity between the human being and the Absolute in Indian philosophical knowledge Belyi directs his readers’ attention to the divine nature of people.
A comprehensive examination of procedures for testing the significance of a correlation matrix and its elements

description: Correlational techniques are important tools in multivariate behavioural and social science exploratory research. A wide array of procedures have been proposed for testing (a) whether any of the variables are related, and (b) which variables are related. In the current study, the performance of the procedures currently available for testing these distinct questions is assessed on the primary Neyman-Pearson criterion for an optimal test. According to this criterion, an optimal procedure is the most powerful procedure that controls experimentwise Type I error rate at or below the nominal level. The findings of the first part of this study addressing how to test complete multivariate independence suggest that the statistic traditionally used (QBA) is not the optimal test, and that one of several recently derived statistics (QSE> QSA> QF) should be used. Computational efficiency of the procedures is also considered with the resulting recommendation of the use of QSA- The second part of this study addresses how to test which variables are correlated; the findings suggest the use of a multi-stage order statistics approach with z-tests (CF). The conditions necessary to ensure maximal power when addressing these questions are also considered.

description: The purpose of our thesis is the point out the determinative position that practical training holds in the studies of future teachers, in terms of the broader purport and philosophy of the studies that a teacher's training college includes. Aiming at the preceding particular target, in the theoretical part of our thesis, we primarily touch upon the education of educators in general, not only as far as Greece is concerned, but also in terms of abroad. Further on, we focus on the position and the role of practical training in the programme of studies of teacher's education. By means of the investigate part of our thesis, particularly, our main concern lies on the evaluation of the programme of "Teaching Methodology and Practice" of the Florina department of Primary Education. In order to evaluate this programme, we heldempirical researches, so that we will have an overall estimation of the T.M.P.T. programme's effectiveness and also to find out at what degree the students accepted and were satisfied by the programme. In addition to this, we wanted to detect theoretical weakness as well as practical and organizational problems in its function. The results of the research verified adequately our primary suppositions. The students of D.P.E. in Florina agree with the aims, while the contents and the organization of T.M.P. satisfy them

description: It was shown that quantum metric fluctuations smear out the singularities of Green's functions on the light cone [1], but it does not remove other ultraviolet divergences of quantum field theory. We have proved that the quantum field theory in Krein space, {\it i.e.} indefinite metric quantization, removes all divergences of quantum field theory with exception of the light cone singularity [2,3]. In this paper, it is discussed that the combination of quantum field theory in Krein space together with consideration of quantum metric fluctuations, results in quantum field theory without any divergences.

description: We consider chains of generalized submanifolds, as defined by Gualtieri in the context of generalized complex geometry, and define a boundary operator that acts on them. This allows us to define generalized cycles and the corresponding homology theory. Gauge invariance demands that D-brane networks on flux vacua must wrap these generalized cycles, while deformations of generalized cycles inside of a certain homology class describe physical processes such as the dissolution of D-branes in higher-dimensional D-branes and MMS-like instantonic transitions. We introduce calibrations that identify the supersymmetric D-brane networks, which minimize their energy inside of the corresponding homology class of generalized cycles. Such a calibration is explicitly presented for type II N=1 flux compactifications to four dimensions. In particular networks of walls and strings in compactifications on warped Calabi-Yau's are treated, with explicit examples on a toroidal orientifold vacuum and on the Klebanov-Strassler geometry.

description: The far right is notoriously effective in its use of digital media to mobilize people and to build a sense of collective identity around oppositional cultures. Yet, while research has begun to explore far-right groups’ social media hyperlinking activities, relatively little is known about the purposes and communicative functions of this form of communication. By combining social network analysis and qualitative content analysis on Facebook data obtained from 17 PEGIDA and Generation Identity Facebook pages in the period around the so-called ‘refugee crisis’ (2015–2017), this exploratory study investigates the linked source types and their purposes. We find that the groups predominantly link to mainstream media, far-right media and far-right non-institutional groups. While there are great overlaps in the communicative functions and purposes of the links for the two networks, the PEGIDA groups mainly focus on the promotion of political issues, especially around the opposition to third-country (Muslim) immigration, while the GI groups use them for self-promotional purposes. These differences are largely explainable by the groups’ adverse (online) mobilization aims.

description: To explore the relationship between serum uric acid (UA) and high-density lipoprotein cholesterol (HDL-C) ratio (UHR) and metabolic syndrome (MetS) in nondiabetic individuals. A total of 15,760 nondiabetic participants were screened from the China National Diabetes and Metabolic Disorders Study. Pearson correlation was used to determine the correlation between the components of MetS and UHR, HDL-C, and UA. Receiver operating characteristic curves were used to evaluate the ability of UHR, HDL-C, and UA to identify MetS in the nondiabetic population. A total of 6,386 men and 9,374 women were enrolled in this study. There were 1,480 (23.2%) men and 1,828 (19.5%) women with MetS. UHR significantly correlated with the components of MetS in men and women, especially with waist circumference  and triglyceride. In men, although HDL-C showed a higher specificity index, UHR presented higher sensitivity index and area under the curve (AUC) than HDL-C (P = 0.0001) and UA (P < 0.0001), with AUC (95% CI) of 0.762 (0.752–0.773). Higher AUCs of UHR relative to HDL-C and UA were also observed in the age groups <40 and 40–59 years. There was no significant difference in AUC between UHR and HDL-C in the age group ≥60 years (P = 0.370). However, similar results were not observed in women. UHR significantly correlated with the components of MetS and could serve as a novel and reliable marker for identifying the population at a high risk of MetS in nondiabetic men, especially in younger adults.

description: Mathematical modelling of ionic electrodiffusion and water movement is emerging as a powerful avenue of investigation to provide new physiological insight into brain homeostasis. However, in order to provide solid answers and resolve controversies, the accuracy of the predictions is essential. Ionic electrodiffusion models typically comprise non-trivial systems of non-linear and highly coupled partial and ordinary differential equations that govern phenomena on disparate time scales. Here, we study numerical challenges related to approximating these systems. We consider a homogenized model for electrodiffusion and osmosis in brain tissue and present and evaluate different associated finite element-based splitting schemes in terms of their numerical properties, including accuracy, convergence, and computational efficiency for both idealized scenarios and for the physiologically relevant setting of cortical spreading depression (CSD). We find that the schemes display optimal convergence rates in space for problems with smooth manufactured solutions. However, the physiological CSD setting is challenging: we find that the accurate computation of CSD wave characteristics (wave speed and wave width) requires a very fine spatial and fine temporal resolution.

In the recently published diary and in the letters he wrote to his lover Jerzy Błeszyński, this theme becomes explicit and allows for a correct depiction of the role that sexuality played in the writer’s life and work. Substitution, comparison, revelation, sacralisation and artistic sublimation are some of the practices identified in the essay in order to trace homosexual discourse in this autobiographical material, a discourse that appears to be closely connected to modernist poetics alongside its philosophical and cultural implications (Nietzsche, Gide, Proust, Wilde, Szymanowski), but also tabooed by the writer himself.

description: Recent studies have shown that the stricter content moderation policies imposed by mainstream social networking sites (SNSs) stimulated the growth of low-moderated but relatively open discussion platforms such as Telegram. Despite Telegram’s growing popularity among (deplatformed) digital exiles, and high potential for news dissemination, information consumption, mobilization, and radicalization, little is known about information flows with respect to politically and socially relevant topics within the Telegramsphere. We scrutinize the Telegramsphere as an information-sharing ecosystem of current affairs by uncovering how information flows indicated by content-overlap and shared users influenced the structure of Telegram networks and shaped communities over time. Using state-of-the-art web-mining, neural topic modeling, and social network analysis techniques on a unique data set that spans the full messaging history (N = 2,033,661) of 174 Dutch-language public Telegram chats/channels, we show that over time, conspiracy-themed, far-right activist, and COVID-19-sceptical communities dominated the Dutch Telegramsphere of current affairs. Our findings raise concerns with respect to Telegram’s polarization and radicalization capacity in the context of consuming socially and politically relevant information online.

description: So far, only transient Gravitational waves (GWs) produced by catastrophic events of extra-galactic origin have been detected. However, it is generally believed that there should be also continuous sources of GWs within our galaxy, such as accreting neutron stars (NSs). In fact, in accreting NSs, centrifugal forces can be so strong to break the neutron star crust (causing a starquake), thus producing a quadrupole moment responsible for the continuous emission of GWs. At equilibrium, the angular momentum gained by accretion and lost via GWs emission should balance each other, stopping the stellar spin-up. We hereinafter investigate the above physical picture within the framework of a Newtonian model describing compressible, non-magnetized, and self-gravitating NSs. In particular, we calculate the rotational frequency need to break the stellar crust of an accreting pulsar and we estimate the upper limit for the ellipticity due to this event. Depending on the equation of state (EoS) and on the mass of the star, we calculated that the starquake-induced ellipticity ranges from $10^{-9}$ to $10^{-5}$. The corresponding equilibrium frequency that we find is in good agreement with observations and, for all the scenarios, it is below the observational limit frequency of $716.36$ Hz. Finally, we also discuss possible observational constraints on the ellipticity upper limit of accreting pulsars.

description: The quality of astronomical spectra is now so high that the accuracy of the laboratory data is getting more and more important for the analysis and interpretation. Both in astrophysics and cosmology the needs for accurate laboratory wavelengths have increased with the development of new ground-based and air-borne telescopes and spectrographs. The high resolution UV Fourier Transform spectrometer at Lund Observatory is being used for studying laboratory spectra of astrophysically important elements. Measurements of accurate laboratory UV and IR wavelengths have been made for cosmological and astrophysical applications.

title: Russian Letters from the Front: Egodocuments and Witnesses of Time

Publisher: name: AvtobiografiЯ

description: In the center of the article is the phenomenon of the front epistle, considered on a selection of attributed letters from Russians, from various fronts of the twentieth century. The letter from the front is a personal egodocument, telling about the attitude of a combatant in the context of the front and its circumstances, and, at the same time, a reflection of the discursive regime of the era that defined and shaped the dominant modes of written communication. We restrict ourselves to the subject of the changed professional attitude to war. A socially oriented narrative analysis of letters from the front allows us to outline the leading leitmotifs of the plot of "work in war", the evolution of military professionalism, military ethos and public discourse about it. The war already appears in the later epistle in its undisguised form - as a solution to tasks to destroy the enemy, and subjectively – as a personal survival.

description: We have addressed the challenge to carry out the angular tilt stabilization of a laser guiding mirror which is intended to route a laser beam with a high energy density. Such an application requires good angular accuracy as well as large operating range, long term stability and absolute positioning. We have designed an instrument for such a high precision angular tilt measurement based on a triangulation method where a laser beam with Gaussian profile is reflected off the stabilized mirror and detected by an image sensor. As the angular deflection of the mirror causes a change of the beam spot position, the principal task is to measure the position on the image chip surface. We have employed a numerical analysis of the Gaussian intensity pattern which uses the nonlinear regression algorithm. The feasibility and performance of the method were tested by numeric modeling as well as experimentally. The experimental results indicate that the assembled instrument achieves a measurement error of 0.13 microradian in the range +-0.65 degrees over the period of one hour. This corresponds to the dynamic range of 1:170 000.

description: Η έλευση στην Ελλάδα ενάμιση περίπου εκατομμυρίου προσφύγων της Μικράς Ασίας το 1922 άλλαξε την ισορροπία των πολιτικών δυνάμεων του Μεσοπολέμου. Εως την εγκαθίδρυση της δικτατορίας του Μεταξά το 1936, οι πρόσφυγες υπήρξαν ουσιαστικά ο ρυθμιστικός παράγοντας σε κάθε εκλογική αναμέτρηση. Ο πολιτικός κόσμος της εποχής θεώρησε δεδομένη την προσήλωσή τους στο κόμμα των Φιλελευθέρων, επειδή πριν από την Καταστροφή είχαν υποστηρίξει την αλυτρωτική πολιτική του Ελευθέριου Βενιζέλου και είχαν συνδέσει τον ξεριζωμό τους με την πολιτική που είχαν ασκήσει η Δυναστεία και η αντιβενιζελική παράταξη. Μετά το 1922 οι πρόσφυγες υποστήριξαν τα βενιζελικά κόμματα και ανέδειξαν τους πολιτικούς εκπροσώπους τους μέσα από τα προσφυγικά σωματεία που ίδρυσαν, για να ασκήσουν πιέσεις για την ολοκλήρωση της αποκατάστασή τους. Οι εκλογές του 1932 αποτελούν τομή, επειδή σημειώνονται οι πρώτες διαρροές προν την αντιβενιζελική παράταξη και το Κομμουνιστικό κόμμα, οι οποίες διευρύνονται στις εκλογές του 1933 η εργασία αυτή, έχοντας ως κύρια πηγή τα πρακτικά των προσφυγικών σωματείων και των παμπροσφυγικών συνεδρίων αναδεικνύει τις διαδικασίες μέσα από τις οποίες ξεχώρισαν οι εκπρόσωποι των προσφύγων, τις θέσεις που διατύπωσαν και πως η ένταξή τους στη συνέχεια σε συγκεκριμένους κομματικούς σχηματισμούς επηρέασε την ψήφο των προσφύγων
description: The coming of approximately one million of refugees from Minor Asia to Greece in 1922 changed the aquilibrium of political forces during the Interwar. Until the establishment of Metaxa's dictatorship in 1936, the refugees had virtuality been the regulatory factor in every electoral confrontation. The contemporary political people took the refugees attachment to the Liberal party for granted, since, before the Destruction, the refugees had supported the Eleftherios Venizelos's liberation policy, and they had associated their expatriation with the policy the Dynasty and the Antivenizelian party had followed. After 1922 the refugees's unions they had already founded, in order to exert pressure as far as the completion of their rehabilitation was concerned. The elections in 1932 constitute a milestone, given that the first leakages towards the Anti-Venizelian and the Communist parties occured then and broadened during the leections in 1933. This thesis, whose primary source of information was the proceedings of the refugees' unions and their conferences, illuminates the process through the refugees' representatives stood out, the viewpoints they latter stated, as well as how their future integration in specific political formations affected the refugees' voting

description: This work presents a system identification procedure based on Convolutional Neural Networks (CNN) for human posture control using the DEC (Disturbance Estimation and Compensation) parametric model. The modular structure of the proposed control model inspired the design of a modular identification procedure, in the sense that the same neural network is used to identify the parameters of the modules controlling different degrees of freedom. In this way the presented examples of body sway induced by external stimuli provide several training samples at once.

description: Through the collection of digital media and engagement with underrepresented groups, memory institutions aspire to preserve and interpret a range of contemporary perspectives on culture and identity. These institutions simultaneously seek to provide experiences that foster civic identities and cultural citizenship. This article explores the potential of collecting internet memes, a specific form of digital media, to further these institutional aims. Through an empirical study of a youth engagement program at a Norwegian folklore archive, we conclude that collecting and contextualizing image macros in collaboration with young people is an institutionally viable and inclusionary approach to documenting new expressions of culture and everyday life. The project further created a context in which young people could exercise competencies related to the development of a civic identity. These findings are relevant for cultural heritage institutions which aim to diversify the forms of digital media, knowledge practices and perspectives represented in their collections, and for cultural heritage professionals who aim to engage youth or marginalized communities. Extending recent research on internet memes as resources for meaning-making the study also underscores the value of participatory research methodologies which deliberately invite individuals’ interpretations of digital culture and analytical approaches that account for the richness of internet memes and image macros as semiotic resources for narrating identity.
