description: Σύμφωνα με τη θεωρία του νομιναλισμού δεν υπάρχουν γενικές ή καθολικές ή αφηρημένες έννοιες, αλλά μόνο απλές , μη αντικειμενικές. Ο Λοκ υπήρξε ένας από τους εκφραστές του με σημαντικότερο έργο του το "Δοκίμιο για την ανθρώπινη νόηση" όπου αναπτύσσει τη θεωρία των ιδεών. Η λέξη ιδέα χρησιμοποιείται για να δηλώσει κάθε αντικείμενο της νόησής μας. Αμφισβητείται η θεωρία ότι υπάρχουν έμφυτες αρχές και ιδέες. Οι ιδέες προκαλούν τη γνώση με τη βοήθεια της εμπειρίας. Ο Λοκ τις κατηγοριοποιεί σε παλές και σύνθετες, ωστόσο δεν βρίσκει μια σταθερη οριοθετική γραμμή ανάμεσά τους. Ενάντια στη θεωρία των γενικών ιδεών άσκησε κριτική ο Μπέρκλευ ο οποίος θεωρεί την επινόηση των γενικών ιδεών αποτέλεσμα της ύπαρξης γλωσσικών εκφράσεων με γενική χρήση και της αντιμετώπισης των λέξεων ως ονόματα. Επίσης διαφωνεί με τον Λοκ και στον τρόπο αντίληψης των πραγμάτων. Η δική του προσέγγιση του επιτρέπει να διατυπώσει την περίφημη, αλλά δυσερμήνευτη αρχή "esse est percipi", μέσα από τη μελέτη της οποίας συμπεραίνουμε ότι ο ιδεαλισμός του Berkeley είναι εμπειρικός. Ωστόσο δεν κατάφερε να απαλλαγεί από την παραδοσιακή έννοια της ουσίας.
description: According to the philosophical theory of nominalismus there are not general, universal or abstract ideas, but only siple not objective. Locke was one of its supporters. his more significant work is "Essay about human understanding", in which he describes the theory of ideas. The word idea is used in order to declare every subject of our understanding. The theory that there are innate principles and ideas is disputed. From the ideas the knowledge arises through the experience. Lock divides the ideas into simple and compound, but he doens't fined limits between them.Berkeley put criticism against the theory of the general principles. He thinks that the invention of the general ideas is a result of the existence of lingual expressions with general use and of the facing of the words as names. Also, he disagrees with Locke about the way he understands the things. His approach allows him to express the famous, but also non explainable princile "Esse est percipi". through which we conclude that the idealism of Berkeley is empiric. Nevertheless didint succeed to get away of the traditional emaning of the substance. Finally Berkeley considers God as the cause of the coming arrival of the ideas
When invariable cross-sections change: the Electron-Ion Collider case

description: In everyday research, it is tacitly assumed that the scattering cross-sections have fixed values for the given particle species, centre-of-mass energy, and particle polarizations. However, this assumption has been called into question after several observations of suppression of high-energy bremsstrahlung. This process will play a major role in experiments at the future Electron-Ion Collider, and we show here how variations of the bremsstrahlung cross-section can be profoundly studied there using the lateral beam displacements. In particular, we predict very strong increase of the observed cross-sections for large beam separations. We also discuss the relation of these elusive effects to other quantum phenomena occurring over macroscopic distances. In this context, spectacular and possibly useful properties of the coherent bremsstrahlung at the EIC are also evaluated.

Principles of the Concept-Oriented Data Model
Creators: name: Savinov, Alexandr
Publisher: name: arXiv
Year: 2008
Subjects: subject: Databases (cs.DB)
subject: FOS: Computer and information sciences

description: In the paper a new approach to data representation and manipulation is described, which is called the concept-oriented data model (CODM). It is supposed that items represent data units, which are stored in concepts. A concept is a combination of superconcepts, which determine the concept's dimensionality or properties. An item is a combination of superitems taken by one from all the superconcepts. An item stores a combination of references to its superitems. The references implement inclusion relation or attribute-value relation among items. A concept-oriented database is defined by its concept structure called syntax or schema and its item structure called semantics. The model defines formal transformations of syntax and semantics including the canonical semantics where all concepts are merged and the data semantics is represented by one set of items. The concept-oriented data model treats relations as subconcepts where items are instances of the relations. Multi-valued attributes are defined via subconcepts as a view on the database semantics rather than as a built-in mechanism. The model includes concept-oriented query language, which is based on collection manipulations. It also has such mechanisms as aggregation and inference based on semantics propagation through the database schema.

description: The orthant model is a directed percolation model on $\mathbb{Z}^d$, in which all clusters are infinite. We prove a sharp threshold result for this model: if $p$ is larger than the critical value above which the cluster of $0$ is contained in a cone, then the shift from $0$ that is required to contain the cluster of $0$ in that cone is exponentially small. As a consequence, above this critical threshold, a shape theorem holds for the cluster of $0$, as well as ballisiticity of the random walk on this cluster.

description: Distributed-order fractional non-local operators have been introduced and studied by Caputo at the end of the 20th century. They generalize fractional order derivatives/integrals in the sense that such operators are defined by a weighted integral of different orders of differentiation over a certain range. The subject of distributed-order non-local derivatives is currently under strong development due to its applications in modeling some complex real world phenomena. Fractional optimal control theory deals with the optimization of a performance index functional subject to a fractional control system. One of the most important results in classical and fractional optimal control is the Pontryagin Maximum Principle, which gives a necessary optimality condition that every solution to the optimization problem must verify. In our work, we extend the fractional optimal control theory by considering dynamical systems constraints depending on distributed-order fractional derivatives. Precisely, we prove a weak version of Pontryagin's maximum principle and a sufficient optimality condition under appropriate convexity assumptions.

description: Οι συγκεντρώσεις έξι μετάλλων (Cr, Cu, Pb, Mn, Ni, Zn) προσδιορίστηκαν σε τέσσερα φυτικά είδη τα οποία συλλέχθηκαν από την περιοχή του Α.Η.Σ. Αγίου Δημητρίου Κοζάνης. Eπιλέχθηκαν δύο καλλιεργούμενα είδη, το Zea mays L. και το Brassica oleracea var. capitata, όπως επίσης και δύο αυτοφυή, το Rumex acetosa L. και το Verbascum phlomoides L.. Η ανάλυση έγινε με τη μέθοδο της φασματοφωτομετρίας ατομικής απορρόφησης μετά την ξήρανση και την πέψη των δειγμάτων. Η μέση συσσώρευση των μετάλλων στα εδαφικά δείγματα ακολουθεί τη σειρά: Mn> Cr> Ni> Zn> Pb> Cu, ενώ για τα φυτικά δείγματα η σειρά έχει ως εξής: Zn> Mn> Ni> Cr> Cu> Pb. Στους σταθμούς δειγματοληψίας που βρίσκονται κοντά στον ατμοηλεκτρικό σταθμό βρέθηκε υψηλή συγκέντρωση χρωμίου στα εδαφικά δείγματα σε σχέση με τους πιο απομακρυσμένους. Η ρίζα των φυτών εμφάνισε μεγαλύτερη συσσώρευση μετάλλων από τα υπέργεια τμήματα. Όσον αφορά τα φύλλα, τα πιο επιβαρυμένα είναι αυτά που έχουν πιο αδρή επιφάνεια, όπως το Verbascum phlomoides το οποίο φέρει μη αδενικά πολυκυτταρικά διακλαδιζόμενα τριχίδια. Γενικά, τα γηραιότερα φύλλα είναι τα περισσότερο επιβαρυμένα. Στην περίπτωση του Zea mays L., τα σπέρματα συσσωρεύουν τη μικρότερη ποσότητα βαρέων μετάλλων σε σχέση με τα υπόλοιπα όργανα του φυτού.
description: Concentrations of six metals (Cr, Cu, Pb, Mn, Ni, and Zn) were determined in four plant species collected from the area of Coal Power Plant (CPP) - A. Dimitrios, Macedonia. Two cultivated, Brassica oleracea var. L capitata and two non cultivated plants, Rumex acetosa L. were chosen. The mean heavy metal content in the soil is described in the descending order of Mn>Cr>Ni>Zn>Pb>Cu, while for the plant material the order was Zn>Mn>Ni>Cr>Cu>Pb. Stations in the vicinity of the CPP showed a distinctly high load of Cr in the soil, whereas for the other metals no such correlation has been noted. In general, roots revealed a higher metal concentration than that of the other plant organs. The most contaminated leaves showed a variation in surface roughness. In Verbascum phlomoides (mullein) the non-glandular, multicellular, branched candelabrum-like trichomes on the leaf epidermis trapped and retain a considerable number of particles effectively. In contrast, the waxy cuticle of Rumex acetosa, which forms a smooth sheet over the epidermal cells, enabled the fast removal of the particles by rain or wind. In the case of Zea mays seeds accumulate the lowest amount of all metals (extended abstract on page 115).

description: Longitudinal and shear ultrasonic velocities in the ternary tellurite glasses have been measured at room temperature with different percentages of the third component. The ternary tellurite glasses have the form (composition in mol%): 70 TeO2 - (30-x) V2O5 - xAnOm, where ΑnΟm is CeO2 or ZnO, and x = 3, 5, 7, 10 mol%. The elastic properties, longitudinal, shear, bulk and Young's modulus, have been calculated together with Poisson's ratio and Debye temperature. Α qualitative analysis has been carried out after calculating the ring diameter of the glass network, Quantitatively, the estimated bulk modulus and Poisson's ratio of the ternary TeO2-V2O5-CeO2 system have been calculated, using the bond compression model and according to the cation-anion bond of each oxide present in the glass, in order to analyze the room-temperature elastic moduli data. Information about the structure of the glass can be deduced after calculating the number of network bonds per unit volume, the average stretching force constant, the average ring size and the mean cross link density.

description: Η συνδεσιμότητα του δικτύου είναι πολύ σημαντική παράμετρος σε ad hoc δίκτυα, όπου η επικοινωνία των κόμβων βασίζεται σε επικοινωνία τύπου πολλαπλών βημάτων (multihop). Η συνδεσιμότητα έχει μεγάλη επίδραση στην απόδοση του συστήματος. Για τον λόγο αυτό η γνώση των ιδιοτήτων του δικτύου πρέπει να στηρίζεται στη σωστή ερμηνεία των αποτελεσμάτων της προσομοίωσης. Στην παρούσα εργασία εξετάζουμε την επίδραση των παρεμβολών στη συνδεσιμότητα σε μεγάλου μεγέθους ad hoc δίκτυα, χρησιμοποιώντας θεωρία διήθησης. Θεωρούμε ότι μεταξύ δυο κόμβων μπορεί να υπάρξει αμφίδρομη επικοινωνία αν η αναλογία σήματος προς θόρυβο στον δέκτη του σήματος είναι μεγαλύτερη από την τιμή κατωφλίου. Ο θόρυβος είναι το άθροισμα των παρεμβολών από όλους τους άλλους κόμβους, σταθμισμένο με την μεταβλητή γ, που είναι ο παράγοντας της παρεμβολής, και τον θερμικό θόρυβο του μέσου. Δείχνουμε την υπαρξη κρίσιμης τιμής για τη μεταβλητή γ, για τιμές μεγαλύτερες αυτής το δίκτυο μας αποτελείται από πεπερασμένα ασύνδετα υποσύνολα κόμβων. Αποδεικνύουμε οτι για μη μηδενικές, αλλα αρκετά μικρές τιμές του γ το δίκτυο αποτελείται από μεγάλο (πιθανώς άπειρο) υποσύνολο κόμβων, επιτρέποντας με αυτόν τον τρόπο την επικοινωνία με πολλά βήματα (multiple hop).Τέλος δείχνουμε οτι η πλήρη συνδεσημότητα είναι πολύ δαπανηρή, μειώνοντας όμως τις απαιτήσεις για τη συνδεσιμότητα των κόμβων εξακολουθούμε να έχουμε διήθηση στο δίκτυο, χωρίς να έχουμε μεγάλη απώλεια σε ενέργεια.
description: The network connectivity is one of the important parameters for ad hoc networking, where the communication between nodes relies on the multihop links. It can have a significant impact on the system performance. Therefore, it is important to be aware of the network properties for the correct interpretation of simulation results. In this report we study the impact of interferences on the connectivity of large-scale ad hoc networks, using percolation theory. We assume that a bi-directional connection can be set up between two nodes if the signal to noise ratio at the receiver is larger than some threshold. The noise is the sum of the contribution of interferences from all other nodes, weighted by a coefficient γ, and of background noise. We find that there is a critical value of γ above which the network is made of disconnected clusters of nodes. We also prove that if γ is non zero but small enough, there exist node spatial densities for which the network contains a large (theoretically infinite) cluster of nodes, enabling distant nodes to communicate in multiple hops. Finally we show that full connectivity is very costly property of the network, but slightly loosen the connectivity requirement we can still have percolation in the network, reserving power for further use.
Mechanical properties of microstructurable glasses

description: Microstructurable glasses of the system Li2O-Al2O3-SiO2 are objects of research at the Ilmenau Technical University, Department of Glass- and Ceramics Technology. These glasses also contain alkali oxides and dopants. The dopants are important for the microstructuring. Main directions of research are: the special glass materials, structuring technologies, joining processes and applications. The glasses can be structured with a photolithographic process. This process consists of the following steps: UV exposure, thermal treatment and etching. Using this standard process and variations it is possible to make through structures (e.g. holes), structures with a defined depth, structures with various depths and three-dimensional structures without undercut. Different glass sheets can be joined with a thermal process. Depending on the thermal expansion coefficient glass/metal compounds may be realized by microelectroplating. Deformable structures are very important for applications in the field of measurements and sensors, microgripping technique and microactuators. It is thus necessary to characterize the mechanical properties of these glass structures.

description: The values of the antineutron-nucleus scattering lengths, and in particular their imaginary parts, are needed to evaluate the feasibility of using neutron mirrors in laboratory experiments to search for neutron-antineutron oscillations. We analyze existing experimental and theoretical constraints on these values with emphasis on low $A$ nuclei and use the results to suggest materials for the neutron/antineutron guide and to evaluate the systematic uncertainties in estimating the neutron-antineutron oscillation time. As an example we discuss a scenario for a future neutron-antineutron oscillation experiment proposed for the European Spallation Source. We also suggest future experiments which can provide a better determination of the values of antineutron-nuclei scattering lengths.

description: Industrially melted glasses with the composition (in mol%) 6.5 Na2O ∙ 33.5 B2O3 ∙ 60 SiO2 were thermally treated at temperatures in the range of 660 to 750 °C. This resulted in phase separation, i.e. in the formation of a silica- and a sodium borate-rich phase with an interconnected microstructure. Both, the volume content of the borate-rich phase and the mean structure thickness (the correlation length) increased with time as well as with temperature. The volume content approached to a limiting value at constant temperature. The correlation length increased with time according to a power law (~ t^1/n). By contrast to previous studies, n was in the range of 1 to 1.2 within the temperature range and time scale studied. The correlation lengths were much larger (up to 12 µm) and the viscosities much lower than in most previous studies. The kinetic law was explained as controlled by visous flow.

description: We investigate the growth of a pattern of liquid crests emerging in a layer of magnetic liquid when subjected to a magnetic field oriented normally to the fluid surface. After a steplike increase of the magnetic field, the temporal evolution of the pattern amplitude is measured by means of a Hall-sensor array. The extracted growth rate is compared with predictions from linear stability analysis by taking into account the proper nonlinear magnetization curve M(H). The remaining discrepancy can be resolved by numerical calculations via the finite-element method. By starting with a finite surface perturbation, it can reproduce the temporal evolution of the pattern amplitude and the growth rate. The investigations are performed for two magnetic liquids, one with low and one with high viscosity.

description: A fog-radio access network (F-RAN) architecture is studied for an Internet-of-Things (IoT) system in which wireless sensors monitor a number of multi-valued events and transmit in the uplink using grant-free random access to multiple edge nodes (ENs). Each EN is connected to a central processor (CP) via a finite-capacity fronthaul link. In contrast to conventional information-agnostic protocols based on separate source-channel (SSC) coding, where each device uses a separate codebook, this paper considers an information-centric approach based on joint source-channel (JSC) coding via a non-orthogonal generalization of type-based multiple access (TBMA). By leveraging the semantics of the observed signals, all sensors measuring the same event share the same codebook (with non-orthogonal codewords), and all such sensors making the same local estimate of the event transmit the same codeword. The F-RAN architecture directly detects the events values without first performing individual decoding for each device. Cloud and edge detection schemes based on Bayesian message passing are designed and trade-offs between cloud and edge processing are assessed.

title: Maximizing Fisher information in $\epsilon$-differential privacy mechanisms
Creators: name: Vedak, Matej
Year: 2025

description: Lokale differentielle Privatsphäre (LDP) hat sich als führendes Framework zum Schutz persönlicher Informationen etabliert, selbst gegenüber nicht vertrauenswürdigen Datenanalysten. Obwohl viele Mechanismen die ε-LDP-Bedingungen erfüllen, variiert ihr Nutzen für die statistische Schätzung erheblich. Um dies zu adressieren, maximieren wir die Fisher-Information innerhalb der Menge der ε-LDP-Mechanismen, wodurch die Effizienz nachfolgender statistischer Parameterschätzungen sichergestellt wird. Bisherige Ansätze basierten auf linearer Programmierung mit exponentieller Komplexität $O(2^k)$ (wobei $k=∣\mathscr{X}∣$ die Kardinalität des Eingabealphabets ist), was die praktische Anwendung auf kleine Eingabealphabete beschränkte. Wir entwickeln einen projizierten Gradientenanstiegsalgorithmus mit Kantendurchlauf (PGAET), der eine polynomiale Komplexität von $O(k^9)$ aufweist und somit Optimierungen in hochdimensionalen Kontexten ermöglicht. Wir demonstrieren seine Effizienz anhand diskreter (Poisson) und kontinuierlicher Verteilungen (Cauchy) durch Diskretisierungs- und Approximationsverfahren. Unsere Ergebnisse erweitern die bisher bekannten Resultate auf Eingabealphabetgrößen bis $k=30$, was eine deutliche Verbesserung gegenüber früheren Arbeiten darstellt. Diese Arbeit bietet Forschenden eine Methode, um Datenschutzmechanismen mit größeren Eingabealphabeten zu entwickeln, die gleichzeitig effiziente statistische Schätzungen ermöglichen.
description: Local differential privacy (LDP) has emerged as a leading framework of personal information protection, even from untrusted data analysts. While many mechanisms satisfy $\epsilon$-privacy constraints, their utility for statistical estimation varies significantly. To address this, we maximize Fisher information over the set of $\epsilon$-LDP mechanisms, ensuring efficiency in subsequent statistical parameter estimates. Prior approaches relied on linear programming with exponential complexity $O(2^k)$ ($k=|\mathscr{X}|$, input alphabet cardinality), limiting practical applications to small input alphabets. We develop a projected gradient ascent algorithm with edge traversal (PGAET) that achieves polynomial complexity $O(k^9)$, enabling optimization in high-dimensional settings. We demonstrate its efficiency on discrete (Poisson) and continuous distributions (Cauchy) via discretization and approximation techniques. We extend previously known results to input alphabet sizes up to $k=30$, a significant improvement over previously known results. Our work provides a method for researchers to investigate and construct privacy mechanisms with larger input alphabets that retain efficiency in statistical estimation.

The magnetic response is studied within the recently developed homogenization theory and we in particular study the effects of topology and inhomogeneous broadening. While topology itself mainly affects the Mie resonance frequency we find that the dispersion in the topological radius R of the dielectric rods may lead to significant inhomogeneous broadening and suppression of the negative-mu phenomena for dR/R0 >> epsilon''/epsilon', with epsilon=epsilon'+i*epsilon'' being the relative dielectric function of the rods.

description: Spontaneous breaking of local Lorentz symmetry occurs when a local vector or tensor field acquires a nonzero vacuum expectation value. The effects of such breaking are examined in the context of gravity theory. These include an associated spontaneous breaking of diffeomorphism symmetry and generation of massless Nambu-Goldstone modes. The possibility of a Higgs mechanism is examined as well, and it is found that the conventional Higgs mechanism (giving rise to massive gauge fields) does not occur in a Riemann spacetime. However, in a Riemann-Cartan spacetime a Higgs mechanism involving the spin connection is possible. Despite the lack of a conventional Higgs mechanism in Riemann spacetime, additional massive modes involving the metric can appear through unconventional processes that have no analogue in nonabelian gauge theory. The effects of these types of processes are illustrated using a specific model, known as a bumblebee model, in which a vector field acquires a vacuum value.

An automatic collision response algorithm
Creators: name: Struben, Sonja
Publisher: name: University of British Columbia
Year: 2009

description: Many animations depict two or more objects interacting and potentially colliding. Collision response is a complex process if the objects are intended to respond like soft bodies and to exhibit the properties of real objects. Physically-based models calculate contact forces to incorporate into the calculation of velocities and positions of the control mesh. Some physically-based models, for example those that model cloth, strive for visually realistic results. Until recently the magnitude of the calculations required for physically-based modeling have precluded real-time interaction. A complaint with physically-based models is the correlation between the parameters, such as forces and torques, and the resulting 'look' of the response are sometimes difficult for the user to understand. The work presented in this thesis does not strive for the simulation of real object properties. Instead it tries to remove the interpenetration between two objects while providing a set of controls for the animator to adjust the 'look' of the collision response. A set of data points within the interpentration region of the two colliding objects is determined by the algorithm and each object interpolates those data points to remove the interpenetration. The position of the data points is a function of the relative rigidity of the two objects. Locality or globality of the response is achieved by allowing the user to specify the amount of response absorbed by different levels of a hierarchical B-spline modeling primitive. Combinations of deformational, translational and rotational collision response mechanisms give more options for the look of the response. Empirical results suggest the algorithm's computation time is small enough to allow for a fast preview of the animation, even for moderately complex geometry.

description: The ILC accelerator parameters and detector concepts are still under discussion in the world-wide community. As will be shown, the performance of the BeamCal, the calorimeter in the very forward area of the ILC detector, is very sensitive to the beam parameter and crossing angle choices. We propose here BeamCal designs for a small (0 or 2 mrad) and large (20 mrad) crossing angles and report about the veto performance study done. As illustration, the influence of several proposed beam parameter sets and crossing-angles on the signal to background ratio in the stau search is estimated for a particular realization of the super-symmetric model.

description: Das Grundverständnis menschlicher Freiheit ist der üblichen Unterscheidung von Willens- und Handlungsfreiheit vorgelagert und bezieht sich auf das Vermögen des Menschen, die Haltungen und Bewegungen seines Körpers als persönlichen Ausdruck der Urheberschaft seiner Handlungen zu erfahren. Die kognitionswissenschaftliche Forschung zur Bedeutung der Propriozeption für die vorreflexive Vertrautheit des Handelnden mit seinen Körperhaltungen und -bewegungen wird auf die pragmatistische Konzeption der Elementareinheit des Verhaltens als eine auf Gewohnheiten basierte Austauschbeziehung des Menschen mit seiner Umwelt bezogen, um einen Begriff verkörperter Freiheit zu entwickeln, die darin bestünde, in der Art und Weise, in der wir die uns wichtigen Tätigkeiten ausüben, eine ›gute Figur zu machen‹.

description: Στόχος της παρούσας έρευνας είναι να διερευνήσει σε δείγμα Ελλήνων μαθητών και Ελληνίδων μαθητριών (Ν=214) της Πρωτοβάθμιας και Δευτεροβάθμιας εκπαίδευσης τις πεποιθήσεις τους για τα χαρακτηριστικά του δράστη και του θύματος του σχολικού εκφοβισμού. Σημαντικό ποσοστό των μαθητών και μαθητριών της Πρωτοβάθμιας και Δευτεροβάθμιας εκπαίδευσης δηλώνει ότι ο δράστης του σχολικού εκφοβισμού είναι συνήθως ένα αγόρι, με χαμηλή ακαδημαϊκή επίδοση και ενοχλητική συμπεριφορά προς τους συνομηλίκους του. Από την άλλη μεριά μαθήτριες και μαθητές Πρωτοβάθμιας και Δευτεροβάθμιας εκπαίδευσης σκιαγραφούν το θύμα του σχολικού εκφοβισμού ως κορίτσι με υψηλή ακαδημαϊκή επίδοση. Επιπλέον, σύμφωνα με τις αντιλήψεις μαθητών και μαθητριών της Δευτεροβάθμιας εκπαίδευσης η εκδήλωση του σχολικού εκφοβισμού αλλά και η θυματοποίηση συνδέονται με τη διαφορετική καταγωγή ανάμεσα στο θύμα και στο δράστη. Επιπλέον, στα πλαίσια της παρούσας έρευνας διερευνώνται οι αντιδράσεις των θυμάτων σε καταστάσεις σχολικού εκφοβισμού καθώς και η επίδραση των παραγόντων της ηλικίας, του φύλου και της σχολικής επίδοσης στη διαμόρφωση των αντιλήψεων μαθητών και μαθητριών για τα χαρακτηριστικά του σχολικού εκφοβισμού, του δράστη και των θυμάτων.
description: The present study aims to investigate the perceptions of Greek students (boys and girls), (N=214) of primary and secondary education about individual and personal characteristics of bullies and victims of school bullying. Significant proportion of boys and girls of Primary and Secondary Education outlined bullies as boys with low academic performance and provocative behavior. On the other hand the victims of school bullying were outlined as girls with high academic performance. Moreover, according to the perceptions of secondary students, ethnicity is related to victimization and appearance of school bullying. The study also investigates how victims react to bullying situations and further more examines the effect of age, gender and academic performance to the formation of student’s beliefs about the phenomenon of school bullying and the characteristics of bullies and victims.

description: We use a combination of polarized Raman spectroscopy experiment and model magnetism-phonon coupling calculations to study the rich magneto-Raman effect in the two-dimensional (2D) magnet $\mathrm{CrI_3}$. We reveal a novel layered-magnetism-assisted phonon scattering mechanism below the magnetic onset temperature, whose Raman excitation breaks time-reversal symmetry, has an antisymmetric Raman tensor, and follows the magnetic phase transitions across critical magnetic fields, on top of the presence of the conventional phonon scattering with symmetric Raman tensors in $N$-layer $\mathrm{CrI_3}$. We resolve in data and by calculations that the 1st-order $A_g$ phonon of monolayer splits into a $N$-fold multiplet in $N$-layer $\mathrm{CrI_3}$ due to the interlayer coupling ($N$>=2) and that the phonons with the multiple show distinct magnetic field dependence because of their different layered-magnetism-phonon coupling. We further find that such a layered-magnetism-phonon coupled Raman scattering mechanism extends beyond 1st-order to higher-order multi-phonon scattering processes. Our results on magneto-Raman effect of the 1st-order phonons in the multiplet and the higher-order multi-phonons in $N$-layer $\mathrm{CrI_3}$ demonstrate the rich and strong behavior of emergent magneto-optical effects in 2D magnets and underlines the unique opportunities of new spin-phonon physics in van der Waals layered magnets.

Methanimine as a key precursor of imines in the interstellar medium: the case of propargylimine

description: A gas-phase formation route is proposed for the recently detected propargylimine molecule. In analogy to other imines, such as cyanomethanimine, the addition of a reactive radical (C$_2$H in the present case) to methanimine (CH$_2$NH}) leads to reaction channels open also in the harsh conditions of the interstellar medium. Three possible isomers can be formed in the C$H_2$NH + C$_2$H reaction: Z- and E-propargylimine (Z-,E-PGIM) as well as N-ethynyl-methanimine (N-EMIM). For both PGIM species, the computed global rate coefficient is nearly constant in the 20-300 K temperature range, and of the order of 2-3 $\times$ 10$^{-10}$ cm$^3$ molecule$^{-1}$ s$^{-1}$, while that for N-EMIM is about two orders of magnitude smaller. Assuming equal destruction rates for the two isomers, these results imply an abundance ratio for PGIM of [Z]/[E] $\sim$ 1.5, which is only slightly underestimated with respect to the observational datum.

description: Starting from the model of continuous time random walk, we focus our interest on random walks in which the probability distributions of the waiting times and jumps have fat tails characterized by power laws with exponent between 0 and 1 for the waiting times, between 0 and 2 for the jumps. By stating the relevant lemmata (of Tauber type) for the distribution functions we need not distinguish between continuous and discrete space and time. We will see that, by a well-scaled passage to the diffusion limit, generalized diffusion processes, fractional in time as well as in space, are obtained. The corresponding equation of evolution is a linear partial pseudo-differential equation with fractional derivatives in time and in space, the orders being equal to the above exponents. Such processes are well approximated and visualized by simulation via various types of random walks. For their explicit solutions there are available integral representations that allow to investigate their detailed structure.

Nach der instrumentalistischen Wende: Moralische Verantwortung bei John Dewey
Creators: name: Pitschmann, Annette
Publisher: name: UB Tübingen
Year: 2015

description: Die Einsicht, dass die praktischen Entscheidungen des Einzelnen durch gesellschaftliche Rahmenbedingungen mitbestimmt werden, wirft Fragen hinsichtlich der Struktur moralischer Urheberschaft auf. Wenn der kontingente soziale Rahmen individuelle Handlungen konstituiert, scheint für persönliche Verantwortung kein Raum zu sein. John Deweys instrumentalistische Rekonstruktion des menschlichen Verhaltens eröffnet eine Möglichkeit, diesem Dilemma zu entgehen. Sie ersetzt die bipolare Gegenüberstellung von Individuum und Gemeinschaft, indem sie den umfassenden Begriff des human being als des Trägers individueller und sozialer Eigenschaften ins Zentrum rückt. Dabei zeigt sich, dass die Kontingenz des individuellen Selbst der Zuschreibung von Verantwortung nicht entgegensteht, sondern dass sie diese umgekehrt erst ermöglicht.

Die Unterscheidung zwischen Tatsachen und Werten im Lichte eines undogmatischen Naturalismus
Creators: name: Kertscher, Jens
Publisher: name: UB Tübingen
Year: 2015

description: In der neuzeitlichen Moralphilosophie hat sich im Zeichen des szientistischen Naturalismus der Dualismus von Tatsachen und Werten weitgehend durchgesetzt. John Dewey lehnt als Pragmatist diesen Dualismus ab und will im Rahmen eines undogmatischen Naturalismus die Rede von moralischen Tatsachen rehabilitieren. John McDowell reagiert auf eine ähnliche Problemlage, indem er die Kategorie der ›zweiten Natur‹ für diese Diskussion fruchtbar macht. Der Beitrag diskutiert diese beiden Positionen, die viele Gemeinsamkeiten aufweisen. Im Hinblick auf ihren undogmatischen Umgang mit Naturbegriffen führen sie allerdings in eine Aporie. Es stellt sich daher die Frage, wie der Standpunkt der Praxis ohne Rekurs auf Natur gegen Reduktionsversuche verteidigt werden kann.
