description: Unterrichtsstörungen sind komplexe Situationen und fordern die Lehrpersonen in ihrem Berufsalltag heraus. In der Literatur werden verschiedene Handlungsmöglichkeiten aufgezeigt, es lassen sich jedoch wenig konkrete Hinweise auf notwendige Kompetenzen einer Lehrperson für den konstruktiven Umgang mit Unterrichtsstörungen finden. In dieser Arbeit wird ersichtlich, dass die Selbst-, Beziehungs- und Klassenführungskompetenz ein sinnvolles Kompetenzprofil einer Lehrperson darstellen und bei einer Unterrichtsstörung auch die Prävention und Konfliktauswertung wichtige Phasen sind. Auf die Frage, welche Kompetenz der Lehrperson im konstruktiven Umgang mit einer Unterrichtsstörung zum Tragen kommt, liefern fünf Experteninterviews mit Lehrpersonen der inklusiven Fläming-Grundschule in Berlin, wichtige Daten. Die Auswertung mit der qualitativen Inhaltsanalyse zeigt auf, dass in der Phase der Störung die Beziehungskompetenz zentral ist. Es wird deutlich, dass auf der Grundlage einer professionellen Beziehungsgestaltung, einer mehrperspektivischen Sichtweise und unterstützenden Rahmenbedingungen der konstruktive Umgang mit einer Unterrichtsstörung möglich ist.

description: Background Diabetic polyneuropathy is one of the commonest long-term complications of diabetes. The pain of diabetic peripheral neuropathy could affect the day to day activities of patients and could be troublesome to them. This study required to examine the influence of Diabetic Peripheral Neuropathic Pain on the health related quality of life of type II diabetes patients in our study settings. Objectives: To describe the health related quality of life among type II diabetes patients suffering from diabetic peripheral neuropathic pain in two hospitals (Zewditu Memorial Hospital and St. Paulo Hospital Millennium Medical Collage) in Addis Ababa, Ethiopia 2017 G.C Methods: Facility based comparative cross sectional study was conducted among sample of 220 type II diabetes patients with and without Diabetic Peripheral Neuropathic Pain, who are under the follow up care in Zewditu Memorial Hospital and St. Paul Hospital Millennium Medical Collage Addis Ababa. SF-36 questionnaire was used to collect data on health related quality of life. IBM SPSS statistics version 2015 software was used to analysis, mean score, mean score differences, multivariate analysis of variances and correlation score. Results: The study subjects with Diabetic Peripheral Neuropathic Pain have lower health related quality of life (in all eight domains and two components summary report of SF 36) comparing to those group without Diabetic Peripheral Neuropathic Pain. The mean score difference in all the eight dimensions and both Physical and Mental Health Summary scores of the SF-36 was statistically significant with p-value 0.000 Conclusion: The presence or absence of diabetic peripheral neuropathic pain was found to influence health related quality of life mean score among type II diabetes patients. The domains that were more influenced among SF 36 health related quality of life are role of functioning and emotion. We recommend health care providers to give due attention to painful peripheral neuropathy associated quality of life in diabetic patients.

On the Potential Social Impact of RFID-Containing Everyday Objects

description: Radio Frequency Identification (RFID) is a rapidly evolving technology. While industrialists hope that the use of RFID will bring about great benefits, civil rights activists warn against the dangers. Since RFID pervades everyday life more and more, this paper deals with its potential impact on individuals. Currently private persons are least included in the public debate, although perhaps they will be affected the most by potential negative effects. Critics are especially concerned about the potential violation of privacy. Due to its informational infrastructure RFID could be used for surveillance purposes. Many people therefore fear a surveillance state. Looking at the use of RFID on the product level, completely dynamic pricing and business models could be developed. If everyday objects record and send context sensitive information via embedded RFID tags, this might strongly influence our perception of these objects and our emotional attitude towards them. This relationship between man and RFID containing smart objects is expected to differ from the relationship between man and machines as well as man and computers, as a new function as well as a new significance are added to already well-known objects. Last but not least, this paper also points out RFID's potential impact on health and environment, which has barely been discussed in public so far. The analysis shows that, apart from certain opportunities, considerable risks have to be dealt with. However, panic, as suggested by some critics, seems unreasonable as the development is still wide open. This should rather be considered a great chance: it offers the possibility to play an active role in the shaping of RFID within a legal democratic process. In this process all members of society are likewise responsible for future developments.

description: In this work we illustrate the Arnold diffusion in a concrete example---the \emph{a priori} unstable Hamiltonian system of $2+1/2$ degrees of freedom $H(p,q,I,φ,s) = p^{2}/2+\cos q -1 +I^{2}/2 + h(q,φ,s;\varepsilon)$---proving that for \emph{any} small periodic perturbation of the form $h(q,φ,s;\varepsilon) = \varepsilon\cos q\left( a_{00} + a_{10}\cosφ+ a_{01}\cos s \right)$ ($a_{10}a_{01} \neq 0$) there is global instability for the action. For the proof we apply a geometrical mechanism based in the so-called Scattering map. This work has the following structure: In a first stage, for a more restricted case ($I^*\thicksimπ/2μ$, $μ= a_{10}/a_{01}$), we use only one scattering map, with a special property: the existence of simple paths of diffusion called highways. Later, in the general case we combine a scattering map with the inner map (inner dynamics) to prove the more general result (the existence of the instability for any $μ$). The bifurcations of the scattering map are also studied as a function of $μ$. Finally, we give an estimate for the time of diffusion, and we show that this time is primarily the time spent under the scattering map.

description: Ο σκοπός της παρούσας έρευνας είναι να διευρυνθούν οι σχέσεις της σιωπηρής και της προφορικής αναγνωστικής ευχέρειας με την κατανόηση και με την αποκωδικοποίηση των μαθητών σε επίπεδο ψευδολέξεων και λέξεων. Επιπλέον, ελέγχθηκε το αν υπάρχουν διαφορές στις επιδόσεις των μαθητών όταν η χορήγηση του τεστ της σιωπηρής ευχέρειας διεξάγεται ηλεκτρονικά ή έντυπα. Στην έρευνα συμμετείχαν μαθητές (n=28) της Γ Γυμνασίου, που είχαν ως μητρική γλώσσα την ελληνική, ακολουθούν το τυπικό ακαδημαϊκό πρόγραμμα και δεν είχαν διαγνωστεί με Μαθησιακές Δυσκολίες. Για την αξιολόγηση των μαθητών χρησιμοποιήθηκε η ΔΑΔΑ (Παντελιάδου, Αντωνίου, & Σιδέρης, 2019) και το τεστ σιωπηρής αναγνωστικής ευχέρειας, το οποίο δημιουργήθηκε για τις ανάγκες της έρευνας και βασίστηκε στο TOSCRF (Hammill, Wiederholt, & Allen, 2006). Τα αποτελέσματα έδειξαν πως υπάρχει θετική συσχέτιση ανάμεσα στη σιωπηρή και στη προφορική αναγνωστική ευχέρεια με την αποκωδικοποίηση. Ιδιαίτερα η αποκωδικοποίηση των λέξεων επηρεάζει περισσότερο την αναγνωστική ευχέρεια των μαθητών. Ισχυρή θετική συσχέτιση υπάρχει ανάμεσα και στην αναγνωστική ευχέρεια με την κατανόηση ενώ δε διαπιστώθηκαν στατιστικώς σημαντικές διαφορές στον τρόπο διεξαγωγής της αξιολόγησης
description: The purpose of this study is to investigate the relations among oral and silent reading fluency with reading comprehension and decoding of pseudoword (non words) and words. Furthermore, it is checked for differences in students’ silent fluency when assessment administered electronically or in print. The participants were 28 students of 3th grade of High School, who had Greek as their mother tongue and they have not diagnosed with Learning Disabilities. For the reading assessment of students, DADA (Padeliadou, Antoniou, &Sideris, 2019) and the silent reading test were used, which was created for the needs of the research and was based on the TOSCRF (Hammill, Wiederholt, & Allen, 2006). The results showed that there is a positive correlation of silent and oral reading fluency with decoding. Particularly, the decoding of words has a greater impact on students’ reading fluency. Also, there is a strong positive correlation between reading fluency and reading comprehension and a strong positive correlation with oral reading fluency, but there is not significant differences in the way the assessment was conducted

description: We study microscopic processes responsible for chirality flips in the thermal bath of Quantum Chromodynamics at finite temperature and zero baryon chemical potential. We focus on the temperature range where the crossover from chirally broken phase to quark-gluon plasma takes place, namely $T \simeq (150, 200)$ MeV. The processes we consider are quark-quark scatterings mediated by collective excitations with the quantum number of pions and $σ$-meson, hence we refer to these processes simply as \sugg{to} one-pion (one-$σ$) exchange\sugg{s}. We use a Nambu-Jona-Lasinio model to compute equilibrium properties of the thermal bath, as well as the relevant scattering kernel to be used in the collision integral to estimate the chiral relaxation time $τ$. We find $τ\simeq 0.1 ÷1$ fm/c around the chiral crossover.

description: The U.S. Army is currently working on the development of a new hybrid type of infantryman. Land Warrior is the name for the project which aims at equipping the dismounted soldiers with wearable computers, head-up display, permanent online connection and other technical components. The idea is to link up the dismounted soldier to an information and communications network spanning the whole field of operation. This project sets the stage for the introduction of a completely new type of soldier. It aims not merely at securing a new armament technology, but the complete technical and disciplinary reconfiguration of the soldier. The project transfers to the micro-level of the soldier the whole set of expectations which the military command units and advisers have in mind as a consequence of the epochal changeover to the "Information Age". The change introduced by information technology, so the argument goes, brings with it new kinds of opponents and dangers, but also new opportunities for military strategy. It transforms the entire fabric of geo-political and armament technology. Thus it brings the need for a change of the rationality of organisation of the military: founded on the plan of a "Networkcentric warfare", there is to be a programmatic re-structuring which extends right from the ideas of warfare to the design of the individual soldier. The combination of two research perspectives is used as a heuristical guideline for the empirical presentation. Fundamental assumptions of actor-network theory, and the idea that technical expectations can be seen as far-reaching "prospective structures", lead the gaze to the decisive significance of the main expectation, that of standing at the threshold of the information age. And they bring into sharper focus the idea of network-centric warfare as a programmatic analysis, which translates the technical developments into social demands made on organisational structures, procedures and cultures; and which, conversely, interprets the military definitions of situation, strategic and tactical, as a technological challenge. Drawing on Foucault s analysis of forms of governance and its further extension within governmentality studies, this not only allows a systematic treatment of the reconfiguration of the soldier which this process of change entails, it also shows how thorough-going and farreaching are the transformations of the soldier-subject which are envisioned. And the recourse to the Foucauldian perspective at the same time shows us how a network-type coordination of action, encouraging decentrality and self-organisation, implicitly requires for its precondition a specific kind of subjectivity structured by processes of power.

description: We present a systematic search for periodically varying quasars and supermassive black hole binary (SMBHB) candidates in the Pan-STARRS1 (PS1) Medium Deep Survey's MD09 field. From a color-selected sample of 670 quasars extracted from a multi-band deep-stack catalog of point sources, we locally select variable quasars and look for coherent periods with the Lomb-Scargle periodogram. Three candidates from our sample demonstrate strong variability for more than ~3 cycles, and their PS1 light curves are well fitted to sinusoidal functions. We test the persistence of the candidates' apparent periodic variations detected during the 4.2 years of the PS1 survey with archival photometric data from the SDSS Stripe 82 survey or new monitoring with the Large Monolithic Imager at the Discovery Channel Telescope. None of the three periodic candidates (including PSO J334.2028+1.4075) remain persistent over the extended baseline of 7 - 14 years, corresponding to a detection rate of < 1 in 670 quasars in a search area of 5 deg^2. Even though SMBHBs should be a common product of the hierarchal growth of galaxies, and periodic variability in SMBHBs has been theoretically predicted, a systematic search for such signatures in a large optical survey is strongly limited by its temporal baseline and the "red noise" associated with normal quasar variability. We show that follow-up long-term monitoring (>5 cycles) is crucial to our search for these systems.

Knowledge and attitude towards VCT services; among adolescent high school students in Addis Ababa, Ethiopia
Creators: name: Tassew, Feven

Year: 2005

description: A cross sectional descriptive study was conducted in February – March 2005, in senior secondary high schools found in Addis Ababa town. High school students (grade 9-12) were included in the study to determine their perception and attitude towards voluntary counseling and testing (VCT) services. A multi stage sampling method was used, and 819 students were included for the analysis (97% response rate), to fill out a structured and pre tested questionnaire. A qualitative study with focus group discussion (FGD) was also conducted with two groups (male and female) students selected from anti AIDS club members to supplement some findings from the quantitative data. Among the respondents 436 (53.2%) were males and 383 (46.8%) were females; 161 (19.7%) of the respondents have sexual experience, or ever had sex intercourse, i.e. 22.5% of the males and 16.4% of the total females. The majority, 92.1% of them know (have heard) about VCT services from different sources but only 129 (15.8%) of the students had used the services & 41.4% said it is expensive for them; 59.5% and 52.5% of the students suggested for the VCT services to be located in schools and youth clubs respectively, for a better access to adolescents. During the focus group discussion, the students said they have shortage of reference materials about HIV/AIDS at school and that there is lack of support to anti AIDS clubs in and out of the school. 7 In conclusion, it could be worth considering to involve schools, teachers and anti AIDS clubs to extend VCT services and reach adolescents in an effective way.

description: Spectrum of bosonic scalar-mode excitations in a normal Fermi liquid with a local scalar interaction is investigated for various values and momentum dependence of the scalar Landau parameter $f_0$ in the particle-hole channel. For $f_0 >0$ the conditions are found when the phase velocity on the spectrum of the zero sound acquires a minimum at a non-zero momentum. For $-10$. We also argue that in peripheral heavy-ion collisions the Pomeranchuk instability may occur already for $f_0 >-1$.

title: Cost-efficient factor investing in emerging equity markets
Creators: name: Stankov, Kay
Publisher: name: UNSPECIFIED
Year: 2023

description: When factor investing is applied to emerging equity markets, due to the universe’s illiquid structure, the market friction must be considered. Risk-adjusted on-paper returns of such strategies look particularly appealing, but significant implementation hurdles stand in their path. While factor investing has been well-examined in literature, research gaps remain. This dissertation undertakes three comprehensive studies to resolve existing research gaps concerning portfolio cost-efficiency regarding the trade-off between return and implementation costs in emerging equity markets. Various approaches for further improvement of this trade-off extend the research. The first study demonstrates a factor-based strategy in emerging markets and provides a better understanding of the above trade-off. Multiple sensitivity analyses present the benefits of a first cost-mitigation approach. The second study further seeks to understand equity portfolios’ return and cost dynamics in a macroeconomic context. Leading indicators from developed and emerging markets are utilized to forecast the near-term factor regime. This prediction is adaptively implemented into the portfolios, adds a timing component, and highly increases the cost-efficiency. The third study extends the efficacy of the researched cost-mitigation strategy by implementing the benefits of a stock liquidity prediction based on state-of-the-art machine learning models.

description: Nell’era dell’informazione, l’immenso patrimonio di dati detenuti negli uffici pubblici, può essere messo a disposizione di tutti: cittadini, studiosi, altre entità pubbliche e di ricerca. Dati demografici, nascite, morti con relative cause, rilievi topografici, cataloghi di musei e biblioteche, elementi sulle attività industriali ed artigianali, flussi di traffico… Solo per citare i primi esempi che vengono in mente di una lista quasi infinita. Le norme già ci sono, la diffusione dei dati stenta però a decollare per tanti motivi, dalla penuria di tempo e di personale negli uffici, alla scarsa attitudine mentale degli impiegati, agli applicativi software non ancora adeguati. Con opportune campagne di informazione, e con l’auspicabile svecchiamento della PA, non si tratta tuttavia di un problema insormontabile. Un secondo problema da non sottovalutare è l’anonimizzazione dei dati, che devono essere resi disponibili in forma sufficientemente dettagliata da essere utili e fruibili, ma abbastanza aggregata da non poter risalire all’interessato neppure per via indiretta, questione piuttosto scivolosa nell’era dei big data. Questo rischio si accentua per la peculiarità del territorio italiano, diviso in quasi 8000 Comuni anche molto piccoli. Assumendo comunque che i dati siano disponibili e correttamente gestiti, l’effetto non può che essere positivo per i ricercatori e per chi deve verificare il loro lavoro. Inoltre, poiché non sempre i dati in possesso della PA sono corretti e completi, potrebbe verificarsi anche il percorso inverso, ovvero la correzione di errori ed anomalie rilevate nel corso della ricerca. Insomma, un circolo virtuoso che non è facile innescare ma che, una volta messo in moto, non può che portare benefici a tutta la società.

description: Ribosomal RNA (rRNA) transcription by RNA polymerase I (Pol I) is the first key step of ribosome biogenesis. While the molecular mechanisms of rRNA transcription regulation have been elucidated in great detail, the functional organization of the multicopy rRNA gene clusters (rDNA) in the nucleolus is less well understood. Here we apply super-resolution 3D structured illumination microscopy (3D-SIM) to investigate the spatial organization of transcriptionally competent active rDNA chromatin at size scales well below the diffraction limit by optical microscopy. We identify active rDNA chromatin units exhibiting uniformly ring-shaped conformations with diameters of similar to 240nm in mouse and similar to 170nm in human fibroblasts, consistent with rDNA looping. The active rDNA chromatin units are clearly separated from each other and from the surrounding areas of rRNA processing. Simultaneous imaging of all active genes bound by Pol I and the architectural chromatin protein Upstream Binding Transcription Factor (UBF) reveals a random spatial orientation of regular repeats of rDNA coding sequences within the nucleoli. These observations imply rDNA looping and exclude potential formation of systematic spatial assemblies of the well-ordered repetitive arrays of transcription units. Collectively, this study uncovers key features of the 3D organization of active rDNA chromatin units and their nucleolar clusters providing a spatial framework of nucleolar chromatin organization at unprecedented detail.

description: QCD topological susceptibility at high temperature, $χ_t(T)$, provides an important input for the estimate of the axion abundance in the present Universe. While the model independent determination of $χ_t(T)$ should be possible from the first principles using lattice QCD, existing methods fail at high temperature, since not only the probability that non-trivial topological sectors appear in the configuration generation process but also the local topological fluctuations get strongly suppressed. We propose a novel method to calculate the temperature dependence of topological susceptibility at high temperature. A feasibility test is performed on a small lattice in the quenched approximation, and the results are compared with the prediction of the dilute instanton gas approximation. It is found that the method works well especially at very high temperature and the result is consistent with the instanton calculus down to $T\sim 2\, T_c$ within the statistical uncertainty.

Με βάση την ανασκόπηση της βιβλιογραφίας κρίθηκε αναγκαία η διατύπωση δεδομένων σχετικά με την πανδημία και τις συνέπειες της στην οικογένεια, καθότι πρόκειται για ένα ιδιαίτερα πρόσφατο γεγονός για το οποίο έχει διεξαχθεί ελάχιστος αριθμός ερευνών στην Ελλάδα. Παρατίθενται στοιχεία άλλων χωρών, τα οποία σχετίζονται με τις κοινωνικές και οικονομικές αλλαγές που έχει επιφέρει η πανδημία. Μεθοδολογία : Το δείγμα της μελέτης περιελάμβανε 3.399 ενήλικες που κατοικούσαν στην Ελλάδα κατά την περίοδο επιβολής του μέτρου του εγκλεισμού για την προστασία κατά SARS-CoV-2. Χρησιμοποιήθηκε ένα αυτοσυμπληρούμενο ερωτηματολόγιο διαβαθμισμένης κλίμακας Likert τεσσάρων επιπέδων. Αποτελέσματα : Τα αποτελέσματα έδειξαν αύξηση των αναγκών συναισθηματικής υποστήριξης και επικοινωνίας με τα υπόλοιπα μέλη, ενώ οι συγκρούσεις εντός του οικογενειακού συστήματος παρέμειναν ως είχαν πριν την πανδημία. Τα ευρήματα συζητούνται σε σχέση με τη γενική θεωρία συστημάτων και την ιδιότητα της ανθεκτικότητας του συστήματος, καθώς και σε σχέση με τα ευρήματα που παρουσιάζονται από έρευνες άλλων χωρών σχετικά με τις μεταβολές στην οικογένεια λόγω της καραντίνας. Συμπέρασμα : Η ανάγκη για επικοινωνία και συναισθηματική υποστήριξη στο οικογενειακό πλαίσιο φάνηκε να αυξάνεται κατά την πρώτη περίοδο του εγκλεισμού

Methodology : The sample of the study included 3,399 adults residing in Greece during the period of imposition of the SARS-CoV-2 protection measure. A self-administered four-level Likert graded questionnaire was used. Results: The results showed an increase in the need for emotional support and communication with others, while conflicts within the family system remained. The findings are related to general theory of systems and the resilience of the system, as well as in relation to the research findings from other countries due to quarantine. Conclusion : The need for communication and emotional support in the family context seemed to increase during the first quarantine

description: Metabolic fingerprinting by mass spectrometry aims at the comprehensive, semiquantitative analysis of metabolites. Isotope dilution, if successfully implemented, may provide a more reliable, relative quantification. Therefore, the 13C labeled yeast extract of the IROA TruQuant kit was added as an internal standard (IS) to human urine samples measured in full-scan mode on a high-performance liquid chromatography-time-of-flight mass spectrometer (HPLC–TOFMS) system. The isotope ratio approach enabled the analysis of 112 metabolites. The correlation with reference data did not improve significantly using 12C/13C ratios compared to absolute 12C peak areas. Moreover, using an intricate 13C-labeled standard increased the complexity of the mass spectra, which made correct signal annotation more challenging. On the positive side, the ratio approach helps to reduce batch effects, but it does not perform better than computational methods such as the “removebatcheffect” function in the R package Limma.

description: Introduction: The most predominantly practiced HIV prevention strategy in Ethiopia is the "ABC" approach. However, only the 'use condom' approach can practically be applied to sex workers. If condoms used consistently and properly, and don't break or slip off during sexual intercourse, they prevent the users from acquiring HIV infection and reduce its transmission and slow the spread. Objective: To asses the pattern of condom use and their effectiveness, and related factors. Methodology: Study design was mainly a cross–sectional quantitative study, complemented with a qualitative study, an in–depth interview. Results: A total of 369 CSWs were interviewed. The proportion of CSWs who consistently used condoms for three months and who put condoms onto their male clients' penis at their last sexual intercourse was found to be 85.6% and 35.8%, respectively. Using condoms for contraception purpose had significant statistical association with consistent condom use behavior of sex workers (OR=6.6, 95%CI, 2.3–18.9). The prevalence of condom breakage and slippage at the last sexual intercourse were found to be 4.4%, and 1.5%, respectively. Prolonged sexual intercourse was the only factor believed by almost all IDI participants to cause condom breakage. Trying to continue sexual intercourse after ejaculation and starting sex before a penis being erected properly were believed by IDI participants to cause condom slippage. Discussion: Our consistent condom use finding was grossly similar with that of 2002/BSS finding (85.6% vs. 90.2%). Higher proportion of consistent condom users was observed among Bahir Dar sex workers compared to other study findings like that of Mathias et al viii 1998 (85.6% vs. 40%). The statistical association between consistent condom use and condom use for contraception purpose was also observed in Mathias et al 1998 research (65.3% among condom users vs. 24% among non-users, p<0.001) Conclusion: This study has demonstrated both high proportion of consistent condom use and an encouraging participation of CSWs in putting on condoms to their clients. Keywords: Consistent condom use, Condom breakage, Condom slippage, Commercial sex workers, licensed non-brothel establishments, Non-vaginal sex.

description: Categorical distinctions such as healthy/sick or dead/alive serve to provide orientation and to facilitate decision-making in medicine. This is a major issue in the theory of reflexive modernisation. Recently, new scientific insights within genetics have increasingly prompted the re-drawing of such boundaries. Taking the example of prenatal testing, with particular reference to late term abortion, I investigate the governing rationalities of experts' boundary politics. It will be shown that boundary drawing is structured with reference to society's guiding principles and notions of normality. In those problematic cases where the medical frame is unable to deliver sufficient interpretative power, this reference to societal value orientations turns out to be functional for maintaining the experts' professional authority. In the case of prenatally diagnosable disabilities, for example, experts often do not know how to deal with such diagnoses. This ambiguity is for the most part understood as (cognitive) uncertainty amenable to more research, rather than interpreted as non-knowledge with reference to the level of social action which results from the interpretative failure of biomedical frames. Thus, the interpretation of non-knowledge appears to become unambiguous, which undermines any pending politicisation of non-knowledge. The alignment with society's guiding principles turns out to be functional for maintaining the claim to be able to provide adequate and relevant information and terms for decision-making processes; in other words, for maintaining professional authority. On the basis of the observation that experts have to deal with uncertainty and non-knowledge, the article asks in conclusion whether this could point to the possible emergence of a reflexive type of expert.

description: Die vorliegende Arbeit beschäftigt sich mit den Erfahrungen von Oberstufenschülern mit einer Hörbeeinträchtigung in informellen Gesprächen mit ihren Mitschülern. Um herauszufinden, welche Faktoren in informellen Gesprächen als fördernd beziehungsweise hemmend erlebt werden, wie die Reaktionen in herausfordernden Gesprächen ausfallen und wie der Einfluss des Selbstkonzepts auf das Gesprächsverhalten aussieht, werden sechs Oberstufenschüler in problemzentrierten Interviews befragt. Die Auswertung erfolgt mittels kategorienbasierter Inhaltsanalyse. Es zeigt sich, dass die Teilnahme an Gesprächen aufgrund negativen Verhaltens der Mitschüler und hemmender Gesprächsbedingungen erschwert ist. Obwohl die Beziehungen innerhalb der Klasse positiv bewertet und Gesprächsstrategien angewendet werden, können die Schüler nicht an allen Gesprächen nach Belieben teilnehmen, was zu emotionalen Reaktionen wie Verärgerung oder Missbehagen führt. Das mehrheitlich positive Selbstkonzept der befragten Schüler zeigt sich in einem aktiven Kontaktverhalten und einem konstruktiven Umgang mit herausfordernden Gesprächssituationen.

description: The total contribution of diffuse halo gas to the galaxy baryon budget strongly depends on its dominant ionization state. In this paper, we address the physical conditions in the highly ionized circumgalactic medium (CGM) traced by OVI absorption lines observed in COS-Halos spectra. We analyze the observed ionic column densities, absorption-line widths and relative velocities, along with the ratios of NV/OVI for 39 fitted Voigt profile components of OVI. We compare these quantities with the predictions given by a wide range of ionization models. Photoionization models that include only extragalactic UV background radiation are ruled out; conservatively, the upper limits to NV/OVI and measurements of N$_{\rm OVI}$ imply unphysically large path lengths > 100 kpc. Furthermore, very broad OVI absorption (b > 40 km s$^{-1}$) is a defining characteristic of the CGM of star-forming L* galaxies. We highlight two possible origins for the bulk of the observed OVI: (1) highly structured gas clouds photoionized primarily by local high energy sources or (2) gas radiatively cooling on large scales behind a supersonic wind. Approximately 20% of circumgalactic OVI does not align with any low-ionization state gas within $\pm$50 km s$^{-1}$ and is found only in halos with M$_{\rm halo}$ < 10$^{12}$ M$_{\odot}$. We suggest that this type of unmatched OVI absorption traces the hot corona itself at a characteristic temperature of 10$^{5.5}$ K. We discuss the implications of these very distinct physical origins for the dynamical state, gas cooling rates, and total baryonic content of L* gaseous halos.

description: Το θέμα της συγκεκριμένης διπλωματικής εργασίας σχετίζεται με την αρχαία ελληνική φιλοσοφία και συγκεκριμένα με την εικονοποιία της επαφής στην οντολογία του Πλάτωνα. Αποτελεί μία ερμηνευτική πρόταση για το χωρίο του πλατωνικού διαλόγου Παρμενίδης, όπου συμπεραίνεται πως το Ένα βρίσκεται και ταυτόχρονα δεν βρίσκεται σε επαφή με τον εαυτό του και τα άλλα. Σε τι οφείλεται αυτή η αντιφατική διατύπωση; Πώς θα μπορούσε το άυλο πλατωνικό ον, η Ιδέα, να έρχεται σε επαφή με κάτι, όπως συνέβαινε με τα κοσμολογικά στοιχεία των Προσωκρατικών; Ποια θα μπορούσε να είναι η φύση μίας τέτοιας επαφής; Τα παραπάνω ερωτήματα απαντώνται στα κεφάλαια της εργασίας, όπου παρουσιάζεται η προσωκρατική σύλληψη της ενότητας του κόσμου μέσα από την πολλαπλότητά του, καθώς και οι έννοιες που αναπτύχθηκαν για να την περιγράψουν. Στη συνέχεια, μελετάται η συμβολή του Πλάτωνα σε αυτήν την προβληματική και ο τρόπος που ο ίδιος ενσωμάτωσε αυτήν την αρχαϊκή σύλληψη στη δική του οντολογία της ασώματης ύπαρξης
description: The subject of this thesis is related to ancient Greek philosophy and in particular to the imaginary of contact in Plato’s ontology. It is an interpretative proposal for the passage of the platonic dialogue Parmenides, where it is concluded that the One is and at the same time is not in contact with itself and the others. What is the reason for this contradictory wording? How could ever the immaterial platonic Being, the Form, come into contact with anything, like the cosmological elements of the Presocratics did? What could be the nature of such a contact? The above questions are answered in the chapters of the thesis, which present the conception of the unity of the world through its multiplicity, as well as the notions developed by the Presocratics to describe it. Then Plato's contribution to this problematic is studied, as well as the way he incorporated this archaic concept into his own ontology of incorporeal existence
