description: Στόχος της παρούσας διπλωματικής εργασίας ήταν να προταθούν καινοτόμες υπολογιστικές μέθοδοι για τον αποτελεσματικό εντοπισμό του λαϊκισμού σε μεγάλους όγκους κειμένου. Για το σκοπό αυτό χρησιμοποιήθηκαν, αλλά και αναπτύχθηκαν, μέθοδοι αυτοματοποιημένης ανάλυσης περιεχομένου, όπως η ανάλυση συναισθήματος, η μηχανική μάθηση κ.λπ, οι οποίες στη συνέχεια συγκρίθηκαν μεταξύ τους. Τα δεδομένα πάνω στα οποία εφαρμόστηκαν και εξετάστηκαν οι διάφορες μέθοδοι ήταν 4751 άρθρα διαδικτυακών ενημερωτικών ιστοσελίδων τα οποία συλέχθηκαν με τη μέθοδο του web scraping. Οι συγκεκριμένες ιστοσελίδες είναι έξι και είναι οι ιστότοποι των ακόλουθων εφημερίδων: : «Πρώτο Θέμα», «Η Αυγή», «Η Εφημερίδα των Συντακτών», «Η Καθημερινή», «Τα Νέα», «Το Βήμα». Η φιλοδοξία της συγκεκριμένης εργασίας είναι, μέσω της πρότασης νέων αυτοματοποιημένων μεθόδων, να βοηθήσει τους μελετητές του λαϊκισμού, αλλά και όσους επιθυμούν να ανιχνεύσουν λαϊκιστικό περιεχόμενο στο διαδίκτυο, κάνοντας τη διαδικασία εντοπισμού του λαϊκιστικού περιεχομένου πιο εύκολη και γρήγορη.
description: The aim of this thesis was to propose innovative computational methods for the effective detection of populism in large volumes of text. For this purpose, automated content analysis methods such as sentiment analysis, machine learning, etc. were used and/or developed, and then they were compared to each other. The data on which the various methods were applied and examined were 4751 articles of online news websites which were collected by the web scraping method. Those websites are six and they are the websites of the following newspapers: "Proto Thema", "I Avgi", "The Editors' Newspaper", "I Kathimerini", "Ta Nea", "To Vima". The ambition of this work is, through the proposal of new automated methods, to help populism scholars, but also those who wish to detect populist content on the Internet, to make the process of detecting populist content easier and faster.

description: We use NuSTAR observations of the Galactic Center to search for X-ray lines from the radiative decay of sterile neutrino dark matter. Finding no evidence of unknown lines, we set limits on the sterile neutrino mass and mixing angle. In most of the mass range 10-50 keV, these are now the strongest limits, at some masses improving upon previous limits by a factor of ~10. In the neutrino minimal standard model framework, where additional constraints from dark matter production and structure formation apply, the allowed parameter space is reduced by more than half. Future NuSTAR observations may be able to cover much of the remaining parameter space.

Engineering design of improved power supply current measurement and RF-amplifier layout
Creators: name: I.FAST WP5 Members
Publisher: name: Zenodo
Year: 2023

description: This report concerns technical investigations to mitigate beam current fluctuations on the 100 µs time scale for beams slowly extracted from a synchrotron, referred as spill microstructure. During the first 24 months of the IFAST WP5.3, the engineering design for two technical systems were performed. The first device concerns the measurement of the magnet power supplier ripples (refers to remaining AC current IAC) in the presence of a strong DC current IDC. It comprises a combination of current transformers, and a resolution of almost ΔIAC/IDC = 1x10-7 is reached within a bandwidth of 10 Hz to 40 kHz. The second topic contains the control electronics and power amplification chain for the knock-out extraction. A preliminary yet detailed specification of technical parameters was prepared, while the beam-based experiments were performed. The main observation in the experiments was that spill microstructure depends strongly on the signal shape and excitation bandwidth. The technical design of the power chain was modified to the required power level and bandwidth; and the basic layout was elaborated. For the control, a versatile Software Defined Radio technology can be used; its applicability was demonstrated.

description: The dielectric function of heteroepitaxial YBiO$_3$ grown on $a$-Al$_2$O$_3$ single crystals via pulsed laser deposition is determined in the spectral range from 0.03 eV to 4.5 eV by simultaneous modeling of spectroscopic ellipsometry and optical transmission data of YBiO$_3$ films of different thickness. The (111)-oriented YBiO$_3$ films are nominally unstrained and crystallize in a defective fluorite-type structure with $Fm\bar{3}m$ space group. From the calculated absorption spectrum, a direct electronic bandgap energy of 3.6(1) eV and the signature of an indirect electronic transition around 0.5 eV are obtained. These values provide necessary experimental feedback to previous conflicting electronic band structure calculations predicting either a topologically trivial or non-trivial insulating ground state in YBiO$_3$.

Electrical Conductivity of Quark-Gluon Plasma in Strong Magnetic Fields

Year: 2016

description: We compute the electrical conductivity of quark-gluon plasma in a strong magnetic field $B$ with quantum field theory at finite temperature using the lowest Landau level approximation. We provide the one-loop result arising from 1-to-2 scattering processes whose kinematics are satisfied by the (1+1) dimensional fermion dispersion relation. Due to the chirality conservation, the conductivity diverges in the massless limit, and is sensitive to the value of the current quark mass. As a result, we find that the conductivity along the direction of the magnetic field is quite large compared with the value at $B=0$, mainly because of the small value of the current quark mass. We show that the resummation of the ladder diagrams for the current-current correlator gives rise to only sub-leading contributions beyond the leading-log order, and thus verify our one-loop result at the leading-log accuracy. We also discuss possible implications for the relativistic heavy-ion collisions.

description: We study the equivalence between the recently proposed finite environment quantum jump model and a master equation approach. We derive microscopically the master equation for a qubit coupled to a finite bosonic environment and show that the master equation is equivalent with the finite environment quantum jump model. We analytically show that both the methods produce the same moments of work when the work is defined through the two-measurement protocol excluding the interaction energy. However, when compared to the work moments computed using the power operator approach, we find a difference in the form of the work moments. To numerically verify our results, we study a qubit coupled to an environment consisting of ten two-level systems.

description: Information and communication technologies (ICTs) have been vital during the COVID-19 pandemic. Telehealth and telemedicine services have fulfilled their promise by allowing patients to receive advice and care remotely, making the use of such services the safest route. In the past years, policy makers and researchers have raised ethical, legal and social issues related to the use of ICT in health services. In this paper, firstly are listed the various uses of these new technologies. Then, the framework is set for the ethical issues that may arise from the use of technology in the health sector. Finally, the ethical issues arising from the bibliographic review of the subject are presented and analyzed.
Entanglement entropy for pure gauge theories in 1+1 dimensions using the lattice regularization

description: We study the entanglement entropy (EE) for pure gauge theories in 1+1 dimensions with the lattice regularization. Using the definition of the EE for lattice gauge theories proposed in a previous paper [1] (S. Aoki, T. Iritani, M. Nozaki, T. Numasawa, N. Shiba and H. Tasaki, JHEP 1506 (2015) 187), we calculate the EE for arbitrary pure as well as mixed states in terms of eigenstates of the transfer matrix in 1+1 dimensional lattice gauge theory. We find that the EE of an arbitrary pure state does not depend on the lattice spacing, thus giving the EE in the continuum limit, and show that the EE for an arbitrary pure state is independent of the real (Minkowski) time evolution. We also explicitly demonstrate the dependence of EE on the gauge fixing at the boundaries between two subspaces, which was pointed out for general cases in the paper [1]. In addition, we calculate the EE at zero as well as finite temperature by the replica method, and show that our result in the continuum limit corresponds to the result obtained before in the continuum theory, with a specific value of the counter term, which is otherwise arbitrary in the continuum calculation. We confirm the gauge dependence of the EE also for the replica method.

description: Auf der Grundlage des Resonanz-Tunnel-Heterostruktur-Bipolar-Transistors (RTBT) werden dynamische Digitalschaltungen undArchitekturen vorgestellt, die sich durch eine hohe Funktionsdichte auszeichnen. Ausgehend von einer Analyse der elektrischen Eigenschaften stromgesteuerter Bauelemente (HBT, RTD) wird deren monolithische Verschmelzung zum dreipoligen RTBT dargelegt und anhand von bestehenden Schaltungstechniken analysiert. Durch die Erweiterung des Monostabil-Bistabilen- Logikelement (MOBILE) Konzepts durch den RTBT wird erstmalig ein dynamisches, stromgesteuertes Schaltungskonzept für Quantenbauelemente demonstriert, das die wesentlichen Anforderungen an eine robuste Logikfamilie erfüllt. Die Arbeit zeigt, dass das RTBT-MOBILE bereits die nötige schaltungstechnische Reife für den Einsatz in digitalen Schaltungen wie z.B. linearen Schwellwertgattern, die eine deutliche Reduzierung der logischen Tiefe und der Schaltungskomplexität ermöglichen, besitzt. Im Vergleich zu anderen III-V-Logikfamilien weist die RTBT-MOBILE Logik vergleichbare Schaltzeiten bei geringerer Bauelementanzahl und Verlustleistung auf. Die jüngsten, auf Siliziumhalbleitermaterial basierenden Erfolge von Interband- und Resonanz-Tunnelbauelementen zeigen ein vorhandenes Potential zur Schaltungsfertigung. Damit können die im Rahmen dieser Arbeit vorgestellten Schaltungskonzepte und Designstrategien in die Siliziumtechnologie überführt werden.

description: Large-angle fluctuations in the cosmic microwave background temperature induced by the integrated Sachs-Wolfe effect and Compton-y distortions from the thermal Sunyaev-Zeldovich (tSZ) effect are both due to line-of-sight density perturbations. Here we calculate the cross-correlation between these two signals. Measurement of this cross-correlation can be used to test the redshift distribution of the tSZ distortion, which has implications for the redshift at which astrophysical processes in clusters begin to operate. We also evaluate the detectability of a yT cross-correlation from exotic early-Universe sources in the presence of this late-time effect.

Asymptotically Safe Grand Unification

description: Phenomenologically appealing supersymmetric grand unified theories have large gauge representations and thus are not asymptotically free. Their ultraviolet validity is limited by the appearance of a Landau pole well before the Planck scale. One could hope that these theories save themselves, before the inclusion of gravity, by generating an interacting ultraviolet fixed point, similar to the one recently discovered in non-supersymmetric gauge-Yukawa theories. Employing a-maximization, a-theorem, unitarity bounds, as well as positivity of other central charges we nonperturbatively rule out this possibility for a broad class of prime candidates of phenomenologically relevant supersymmetric grand unified theories. We also uncover candidates passing these tests, which have either exotic matter or contain one field decoupled from the superpotential. The latter class of theories contains a model with the minimal matter content required by phenomenology.

description: Σκοπός της διατριβής ήταν η αξιολόγηση της σχέσης της πανδημίας COVID-19 και της καραντίνας, με το βαθμό επισιτιστικής ανασφάλειας και την ψυχολογική υγεία στην Ελλάδα. Ο φόβος, η ψυχολογική κούραση, η ανεργία, η σύσταση για αποκοινωνικοποίηση και απομόνωση, αυξάνουν την ανησυχία που αισθανόμαστε και επηρεάζουν την ποιότητα της ζωής μας. Η νευρικότητα φαίνεται ότι αυξάνεται, ενώ τα περιστατικά ενδο-οικογενειακής βίας είναι όλο και πιο συχνά. Το αυξημένο άγχος καταστρέφει ή υποβαθμίζει την ποιότητα του ύπνου και η κούραση κυριεύει το σώμα και την ψυχή. Σε ποιο βαθμό όμως επηρεάζεται η διατροφική επάρκεια και η υγιεινή διατροφή από την Πανδημία; Για να προσδιορίσουμε τις επιπτώσεις της πανδημίας, φτιάξαμε ένα ερωτηματολόγιο τεσσάρων ενοτήτων και πραγματοποιήθηκε συλλογή των ερωτηματολογίων, σε διάστημα 3-4 μηνών, μέσω προσκλήσεων σε επαγγελματικούς φορείς, συλλόγους αποφοίτων κλπ., με έμφαση στα επαγγέλματα που έχουν πληγεί από την υγειονομική κρίση. Συγκεντρώθηκαν περισσότερα από 600 που πληρούσαν τα κριτήρια. Μετά από την επεξεργασία των ερωτηματολογίων προσπαθήσαμε να προσδιορίσουμε τις επιπτώσεις της πανδημίας στην διατροφική ανασφάλεια και την ψυχική υγεία. Συγκρίναμε τα αποτελέσματα με άλλες έρευνες και προσπαθήσαμε να βγάλουμε συμπεράσματα για τις επιπτώσεις της πανδημίας στην Ελλάδα.
description: The purpose of the thesis was to assess the relationship between the COVID-19 pandemic and the quarantine, with the degree of food insecurity and psychological health in Greece. Fear, psychological fatigue, unemployment, the recommendation for de-socialization and isolation, increase the anxiety we feel and affect the quality of our lives. Nervousness seems to be on the rise, while incidents of domestic violence are more and more frequent. Increased stress destroys or degrades the quality of sleep, and fatigue overwhelms the body and soul. But to what extent is nutritional adequacy and healthy eating affected by the Pandemic? To determine the effects of the pandemic, we created a questionnaire of four modules and a collection of questionnaires was carried out, within 3-4 months, through invitations to professional bodies, with emphasis on the professions that have been affected by the health crisis. More than 600 who met the criteria were collected. After processing the questionnaires we tried to identify the effects of the pandemic on food insecurity and mental health. We compared the results with other surveys and tried to draw conclusions about the effects of the pandemic on Greece.

description: Optische Wellenleiterkomponenten sind Schlüsselbausteine der optischen Datenübertragungstechnik. Die Herstellung dieser Komponenten auf Basis polymerer Werkstoffe eröffnet die theoretische Möglichkeit zur kostengünstigen Massenfertigung. Im Rahmen dieser Arbeit werden die wesentlichen Abhängigkeiten der optischen Dämpfung passiver integriert einmodiger Polymerwellenleiter sowohl von den strukturellen Eigenschaften der verwendeten Materialien als auch von den technologischen Rahmenbedingungen der Wellenleiterherstellung aufgeklärt. Die Wellenleiterherstellung beruht auf dem sogenannten SIGA-Verfahren. Hier wird die Rauheit der Wellenleiterstrukturen als Hauptfehlerquelle detektiert und der Einfluß auf die Wellenleiterdämpfung theoretisch quantifiziert. Die Eignung verschiedener Copolymersysteme, basierend sowohl auf halogenierten Acrylaten als auch auf halogenierten Polylactonen, für die Verwendung in optischen Wellenleitern wird untersucht. Ein Schwerpunkt dieser Untersuchungen ist u.a. die Visualisierung der chemischen Zusammensetzung der Copolymere im Wellenleiter mittels der Transmissionselektronenmikroskopie. Für die Dämpfung in dB der untersuchten Wellenleitermaterialien im Nahen Infrarot wird eine lineare Abhängigkeit von der C-H-Bindungskonzentration der verwendeten Polymere gefunden.
description: Optical waveguide components are key elements in the optical telecommunication technology. These components may be theoretically fabricated very cost effective using polymers. In this work the optical loss of polymer waveguides is examined as a function of the material structure and also in dependance on the waveguide fabrication technology. The polymer waveguides are fabricated using the so-called SIGA-technology. Surface roughness of the waveguides is determined as a main source for optical waveguide losses, which is theoretically calculated. Several copolymers consisting of halogenated acrylates and halogenated lactones are examined with respect to their applicability in optical waveguides. To determine the chemical composition in the waveguides transmission electron microscopy is used, for example. The optical loss in dB of the waveguide polymers in the near infrared region shows a linear dependance on the C-H-bond concentration in the polymers.

description: The purpose of this master’s thesis was, in the first part, the literature review of various individual topics related to the disease of osteoporosis. We have provided detailed information regarding the epidemiology, risk factors, diagnostic and therapeutic approach as well as the prevention of the disease. In the second part, we proceeded to the statistical analysis and study of the results of a quantitative research on a sample of postmenopausal women. We examined the relationship between the level of physical activity of these women and their levels of bone mineral density. In addition, we recorded baseline anthropometric characteristics of the participants and examined their relationship with bone mineral density level. Next, we detailed the research methodology and presented the results of the statistical analysis. Finally, we presented our conclusions, which we compared with the international published literature.

description: The high room temperature mobility and the electron effective mass in BaSnO$_3$ are investigated in depth by evaluation of the free carrier absorption observed in infrared spectra for epitaxial films with free electron concentrations from $8.3 \times 10^{18}$ to $7.3 \times 10^{20}$~cm$^{-3}$. Both the optical band gap widening by conduction band filling and the carrier scattering mechanisms in the low and high doping regimes are consistently described employing parameters solely based on the intrinsic physical properties of BaSnO$_3$. The results explain the current mobility limits in epitaxial films and demonstrate the potential of BaSnO$_3$ to outperform established wide band gap semiconductors also in the moderate doping regime.

description: Obwohl der Gesundheitssektor einer der wichtigsten Konsumbereiche aus Umweltsicht darstellt, gibt es für diesen bislang kaum ganzheitliche Umweltbewertungen. Dies stellt Spitäler zunehmend vor noch grössere Herausforderungen, Potenzialbereiche für mögliche Umweltoptimierungen herauszuarbeiten, die auch wirtschaftlich tragbar sind.
Das Forschungsprojekt «Green Hospital-Ressourceneffizienz bei Schweizer Spitälern» hat sich zum Ziel gesetzt, bisherige Forschungslücken über umweltrelevante Prozesse in Spitälern zu schliessen sowie konkrete Vorschläge zur ressourceneffizienten Prozessoptimierung auszuarbeiten um damit die Schweizer Spitallandschaft nachhaltiger zu gestalten. Die vier Forschungsziele des Projektes lauten:
1. Entwicklung eines umfassenden Wissens über den Ressourcenverbrauch der Schweizer Spitäler
2. Analyse der Ressourceneffizienz und der Umweltauswirkungen im Gesundheitswesen
3. Ausarbeitung einer Liste umweltfreundlicher Massnahmen und Untersuchung der derzeit realisierbaren Optionen
4. Umsetzung ausgewählter umweltoptimierter Prozesse und Evaluation
An der Erfüllung dieser Forschungsziele arbeiten im interdisziplinären Forschungsteam die Experten der Forschungsgruppe für Ökobilanzierung der Zürcher Hochschule für Angewandte Wissenschaften (ZHAW), die Abteilung «Health Care Logistics» des Fraunhofer Instituts für Materialfluss und Logistik in Dortmund (IML) und das Institut für Wirtschaftsstudien Basel (IWSB) gemeinsam mit Partnerspitälern. Das Forschungsprojekt wurde im Rahmen des Nationalen Forschungsprogramms «Nachhaltige Wirtschaft: ressourcenschonend, zukunftsfähig, innovativ» (NFP 73) des Schweizerischen Nationalfonds (SNF) durchgeführt. Die Resultate dieser Forschung sind im Kapitel 4 zusammengefasst. Dieses Dokument enthält eine Liste umweltfreundlicher Massnahmen aus der Praxis und erfüllt damit das dritte Ziel des Forschungsprojektes. Es kann als Nachschlagewerk und Inspiration für Verbesserungen in den jeweiligen Bereichen genutzt werden. Bei den Massnahmen ist jeweils angegeben, bei welchem Spital diese umgesetzt wurden. Einige Spitäler haben eine Kontaktperson angegeben, an die sich interessierte Personen wenden können, wenn sie mehr über die konkrete Umsetzung lernen möchten.

description: In der vorliegenden Arbeit wird die Synthese von tetracyclischen N,O- und N,S-Hetarene untersucht. Den Ausgangspunkt bildet eine umfassende retrosynthetische Analyse. Isoindolo[2,1-b]benzothiazol ist dabei auf zwei Wegen effektiv zugänglich. Die Herstellung des isocyclischen tetrachlorsubstituierten N,S-Hetarens und des isoelektronischen N,O-Hetarens mittels Cyclisierung durch intramolekulare N-Alkylierung gelingen nicht. Das Reaktionsspektrum von Isoindolo[2,1-b]benzothiazol wird durch elektrophile Substitutionsreaktionen mit C- und N-Elektrophilen und durch [4+2]-Cycloadditionen mit N-substituierten Maleinsäure-imiden überprüft. Die Radikalanionen von tetracyclischen N-Hetarenen mit dem Strukturelement von 1,8-anellierten Naphthalinen werden mit Hilfe der ESR-Spektroskopie untersucht. Umfassende NMR-Untersuchungen begleiten die synthetischen Untersuchungen. Für die untersuchten Zielverbindungen werden semi-empirische Berechnungen (MNDO, AM1, PM3) durchgeführt.
description: In this work the synthesis of tetracyclic N,S- and N,O-heterocyclic compounds is investigated. First a full retrosynthetic analysis is presented. Isoindolo[2,1-b]benzothiazole can be prepared in good yield in two different ways. The synthesis of the isocyclic tetrachlorine-substituted N,S-hetarene and of the isoelectronic N,O-hetarene by means of cyclisation via intramolecular N-alkylation is not successful. The reaction spectrum of isoindolo[2,1-b]benzothiazole is investigated by electrophilic substitutions with C- and N-electrophiles and by [4+2]-cycloadditions with N-substituted maleinimides. The radical anions of tetracyclic N-hetarenes with the element of 1,8-anellated naphthenes are examined using ESR-spectroscopy. Full NMR-investigations accompany the experimental work. Semi-empiric calculations (MNDO, AM1 and PM3) are done for the target compounds.
Non-perturbative analysis of the spectrum of meson resonances in an ultraviolet-complete composite-Higgs model

description: We consider a vector-like gauge theory of fermions that confines at the multi-TeV scale, and that realizes the Higgs particle as a composite Goldstone boson. The weak interactions are embedded in the unbroken subgroup $Sp(4)$ of a spontaneously broken $SU(4)$ flavour group. The meson resonances appear as poles in the two-point correlators of fermion bilinears, and include the Goldstone bosons plus a massive pseudoscalar $η'$, as well as scalars, vectors and axial vectors. We compute the mass spectrum of these mesons, as well as their decay constants, in the chiral limit, in the approximation where the hypercolour $Sp(2N)$ dynamics is described by four-fermion operators, à la Nambu-Jona Lasinio. By resumming the leading diagrams in the $1/N$ expansion, we find that the spin-one states lie beyond the LHC reach, while spin-zero electroweak-singlet states may be as light as the Goldstone-boson decay constant, $f\sim 1$ TeV. We also confront our results with a set of available spectral sum rules. In order to supply composite top-quark partners, the theory contains additional fermions carrying both hypercolour and ordinary colour, with an associated flavour symmetry-breaking pattern $SU(6)/SO(6)$. We identify and analyse several non-trivial features of the complete two-sector gauge theory: the 't~Hooft anomaly matching conditions; the higher-dimension operator which incorporates the effects of the hypercolour axial-singlet anomaly; the coupled mass-gap equations; the mixing between the singlet mesons of the two sectors, resulting in an extra Goldstone boson $η_0$, and novel spectral sum rules. Assuming that the strength of the four-fermion interaction is the same in the two sectors, we find that the coloured vector and scalar mesons have masses $\gtrsim 4 f$, while the masses of coloured pseudo-Goldstone bosons, induced by gluon loops, are $\gtrsim 1.5f$.

description: Time-resolved femtosecond x-ray diffraction patterns from laser-excited molecular iodine are used to create a movie of intramolecular motion with time and space resolution of $30~$fs and $0.3$ Å. The high spatial fidelity is due to interference between the moving excitation and the static initial charge distribution. This x-ray interference has not been employed to image internal motion in molecules before. The initial state is used as the local oscillator for heterodyne amplification of the excited charge distribution to retrieve real-space movies of atomic motion on Ångstrom and femtosecond scales. Coherent vibrational motion and dispersion, dissociation, and rotational dephasing are all clearly visible in the data, thereby demonstrating the stunning sensitivity of heterodyne methods.

description: We consider dark matter physics in a model for the dark sector with extra dark U(1)$_X$ gauge symmetry. The dark sector is composed of exotic fermions that are charged under both dark U(1)$_X$ and the standard model SU(3)$_C \times$U(1)$_Y$ gauge groups, as well as standard model singlet complex scalars $Φ$ and $X$ with nonzero U(1)$_X$ charge. In this model, there are two dark matter candidates$-$a scalar and a fermion$-$both of which are stabilized by accidental $Z_2$ symmetry. Their thermal relic density, and direct and indirect detection constraints are discussed in detail and we search for the parameter space of the model accommodating dark matter observations. We also discuss constraints from diphoton resonance searches associated with the scalar field which breaks the dark U(1)$_X$, in a way consistent with dark matter physics. In addition, implications for collider physics are discussed, focusing on the production cross section of the scalar boson.

description: Das starke Wachstum der geringfügigen Beschäftigung wirft die Frage auf, welche Auswirkungen diese Entwicklung auf betriebliche Beschäftigungssysteme hat. Am Beispiel von zehn Einzelhandelsunternehmen wird gezeigt, dass der zunehmende Anteil geringfügig Beschäftigter in einigen Unternehmen zu einer vertieften Spaltung in eine Stamm- und eine Randbelegschaft führt. In anderen Unternehmen ist trotz hoher Anteile geringfügiger Beschäftigung eine Spaltung des betrieblichen Arbeitsmarktes nicht festzustellen, denn geringfügig Beschäftigte sind hier Teil der Stammbelegschaft. Die Zunahme der geringfügigen Beschäftigung im Einzelhandel ist durch eine Interessenkoalition zwischen Arbeitsnachfrage und Arbeitsangebot zu erklären: Unternehmen erhalten durch Beschäftigte in kurzen Teilzeitbeschäftigungsverhältnissen ein hohes Maß an numerischer Flexibilität und einige Erwerbsgruppen sind in bestimmten Lebensphasen und unter den institutionellen Rahmenbedingungen von Erwerbsarbeit an einer geringfügigen Beschäftigung interessiert. Ob die Regulierung des geringfügigen Beschäftigungsverhältnisses unter beschäftigungspolitischen Gesichtspunkten sowie unter dem Aspekt einer nur eingeschränkten Partizipation bestimmter Erwerbsgruppen am Erwerbssystem gesellschaftlich wünschenswert ist, bleibt zu diskutieren.
description: Marginal part-time is current growing rapidly in Germany. One question is what changes occur in internal labour markets when short-hours, part-time employment is no longer a sporadic, marginal phenomen but a firmly established element of corporate strategies. Research in ten retail companies shows that in some companies the high proportion of 'minijobs' leads to an increased segmentation into core and peripheral workforce while in other companies marginal part-timers belong to the core of the workforce. Taking the societal context of employment, the increasing heterogeneity of work orientations of employees and the demand for numerical flexibility of employers into account the growing number of marginal part-timers in the retail trade can be explained by a coincidence of wishes between the supply and demand side of the labour market. It is debatable whether the regulation of marginal part-time is socially desirable under the aspect of reducing unemployment and with regard to the integration of specific groups into the labour market.
