description: We propose and numerically simulate an optoelectronic compact circular polarimeter. It allows to electrically measure the degree of circular polarization and light intensity at room temperature for a wide range of incidence angles in a single shot. The device, being based on GaAsN, is easy to integrate into standard electronics and does not require bulky movable parts nor extra detectors. Its operation hinges mainly on two phenomena: the spin dependent capture of electrons and the hyperfine interaction between bound electrons and nuclei on Ga$^{2+}$ paramagnetic centers in GaAsN. The first phenomenon confers the device with sensitivity to the degree of circular polarization and the latter allows to discriminate the handedness of the incident light.

description: We revisit the relation between the anomalies in four and six dimensions and the Chern-Simons couplings one dimension below. While the dimensional reduction of chiral theories is well-understood, the question which three and five-dimensional theories can come from a general circle reduction, and are hence liftable, is more subtle. We argue that existence of an anomaly cancellation mechanism is a necessary condition for liftability. In addition, the anomaly cancellation and the CS couplings in six and five dimensions respectively determine the central charges of string-like BPS objects that cannot be consistently decoupled from gravity, a.k.a. supergravity strings. Following the completeness conjecture and requiring that their worldsheet theory is unitary imposes bounds on the admissible theories. We argue that for the anomaly-free six-dimensional theories it is more advantageous to study the unitarity constraints obtained after reduction to five dimensions. In general these are slightly more stringent and can be cast in a more geometric form, highly reminiscent of the Kodaira positivity condition (KPC). Indeed, for the F-theoretic models which have an underlying Calabi-Yau threefold these can be directly compared. The unitarity constraints (UC) are in general weaker than KPC, and maybe useful in understanding the consistent models without F-theoretic realisation. We catalogue the cases when UC is more restrictive than KPC, hinting at more refined hidden structure in elliptic Calabi-Yau threefolds with certain singularity structure.

Empowerment : a multi-level process
Creators: name: Eylon, Dafna
Publisher: name: University of British Columbia
Year: 2008

description: The term "empowerment" is frequently used by organizational researchers, management practitioners, and consultants. However, despite the popularity of the term, there is a lack of empirical work and no generally accepted definition. As part of a thorough multi-disciplinary literature review, fourteen different conceptualizations for the term empowerment were discovered and classified into four categories: Micro (intra-psychic), Meso (relational-interactive), Macro (structural), and Misnomer (bogus). As a result of this work, both a new definition and a multi-level process model of empowerment are offered. Empowerment is defined here as an enhancing and energizing context specific process that expands an individual's power and feelings of trust, is usually facilitated by another, and results in increased levels of self-esteem, self-efficacy and other characteristics related to personal growth and control, which eventually lead to outcomes such as performance and satisfaction. The proposed multi-level process model postulates that the process of empowerment is driven by changes in information, responsibility, and active belief, and mediated by intra-psychic factors. This model was empirically tested in a between-subject, pre-test, post-test simulation design. Over a period of three weeks 135 graduate students completed a novel application of in-basket exercises, within which an empowerment manipulation was embedded. This manipulation included increasing information, responsibility, and active belief for the empowered manipulation and decreasing these three components for the disempowered manipulation. Multivariate analysis of variance revealed that, as predicted, the manipulation had a significant impact on the three mediating intra-psychic factors (self-efficacy, self-esteem, and locus of control) and an analysis of variance found significant results in the predicted direction on the dependent variable of job satisfaction. Regression analyses revealed the predicted mediation relationship between the intra-psychic variables and the dependent variable of job satisfaction. However, none of the analyses yielded significant results for the performance measures (initiative, sensitivity, planning and organizing, delegation, administrative control, problem analysis, judgement, and decisiveness). Several potential explanations are offered for these results, including a motivational interpretation which focuses on participant's motivation directionality. Theoretical and practical implications for these results are discussed as well as directions for future research.

description: The aim of the present thesis was to articulate a proposal on the restoration, enhancement and creation of a network for the ottoman monuments of Giannitsa. In that framework at first we mentioned the most characteristic samples of ottoman architecture in Greece. Subsequently we presented the history of the city of Giannitsa and their ottoman monuments. Then we examined in brief the history of restoration and reuse of the ottoman monuments in Greece. Furthermore we pointed out the basic principles of our proposal. Thereinafter followed the proposals on the restoration and enhancement of each specific monument. Lastly we presented the proposal for the creation of a network for ottoman monuments of Giannitsa, which will be united through an archaeological route. In conclusion our proposal reshapes the urban landscape and aims at the incorporation of the ottoman monuments in the everyday life of the city and at their conversion to a point of reference for the city.

description: Hydrodynamic behavior at the vicinity of a confining wall is closely related to the friction properties of the liquid/solid interface. Here we consider, using Molecular Dynamics simulations, the electric contribution to friction for charged surfaces, and the induced modification of the hydrodynamic boundary condition at the confining boundary. The consequences of liquid slippage for electrokinetic phenomena, through the coupling between hydrodynamics and electrostatics within the electric double layer, are explored. Strong amplification of electro-osmotic effects is revealed, and the non-trivial effect of surface charge is discussed. This work allows to reconsider existing experimental data, concerning Zeta potentials of hydrophobic surfaces and suggest the possibility to generate ``giant'' electro-osmotic and electrophoretic effects, with direct applications in microfluidics.

description: We present a Bayesian method to cross-match 5,827,988 high proper motion Gaia sources ($μ>40 \ mas \ yr^{-1}$) to various photometric surveys: 2MASS, AllWISE, GALEX, RAVE, SDSS and Pan-STARRS. To efficiently associate these objects across catalogs, we develop a technique that compares the multidimensional distribution of all sources in the vicinity of each Gaia star to a reference distribution of random field stars obtained by extracting all sources in a region on the sky displaced 2$^\prime$. This offset preserves the local field stellar density and magnitude distribution allowing us to characterize the frequency of chance alignments. The resulting catalog with Bayesian probabilities $>$95% has a marginally higher match rate than current internal Gaia DR2 matches for most catalogs. However, a significant improvement is found with Pan-STARRS, where $\sim$99.8% of the sample within the Pan-STARRS footprint is recovered, as compared to a low $\sim$20.8% in Gaia DR2. Using these results, we train a Gaussian Process Regressor to calibrate two photometric metallicity relationships. For dwarfs of $3500

description: Modeling the intermittent behavior of turbulent energy dissipation processes both in space and time is often a relevant problem when dealing with phenomena occurring in high Reynolds number flows, especially in astrophysical and space fluids. In this paper, a dynamical model is proposed to describe the spatio-temporal intermittency of energy dissipation rate in a turbulent system. This is done by using a shell model to simulate the turbulent cascade and introducing some heuristic rules, partly inspired by the well known $p$-model, to construct a spatial structure of the energy dissipation rate. In order to validate the model and to study its spatially intermittency properties, a series of numerical simulations have been performed. These show that the level of spatial intermittency of the system can be simply tuned by varying a single parameter of the model and that scaling laws in agreement with those obtained from experiments on fully turbulent hydrodynamic flows can be recovered. It is finally suggested that the model could represent a useful tool to simulate the spatio-temporal intermittency of turbulent energy dissipation in those high Reynolds number astrophysical fluids where impulsive energy release processes can be associated to the dynamics of the turbulent cascade.

description: In this article we study 3D non-Hermitian higher-order Dirac semimetals (NHHODSMs). Our focus is on $C_4$-symmetric non-Hermitian systems where we investigate inversion ($\mathcal{I}$) or time-reversal ($\mathcal{T}$) symmetric models of NHHODSMs having real bulk spectra. We show that they exhibit the striking property that the bulk and surfaces are anti-PT and PT symmetric, respectively, and so belong to two different topological classes realizing a novel non-Hermitian topological phase which we call a \emph{hybrid-PT topological phases}. Interestingly, while the bulk spectrum is still fully real, we find that exceptional Fermi-rings (EFRs) appear connecting the two Dirac nodes on the surface. This provides a route to probe and utilize both the bulk Dirac physics and exceptional rings/points on equal footing. Moreover, particularly for $\mathcal{T}$-NHHODSMs, we also find real hinge-arcs connecting the surface EFRs. We show that this higher-order topology can be characterized using a biorthogonal real-space formula of the quadrupole moment. Furthermore, by applying Hermitian $C_4$-symmetric perturbations, we discover various novel phases, particularly: (i) an intrinsic $\mathcal{I}$-NHHODSM having hinge arcs and gapped surfaces, and (ii) a novel $\mathcal{T}$-symmetric skin-topological HODSM which possesses both topological and skin hinge modes. The interplay between non-Hermition and higher-order topology in this work paves the way toward uncovering rich phenomena and hybrid functionality that can be readily realized in experiment.

Synchrotron emission in the fast cooling regime: which spectra can be explained?
Creators: name: Derishev, E. V.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We consider the synchrotron emission from relativistic shocks assuming that the radiating electrons cool rapidly (either through synchrotron or any other radiation mechanism). It is shown that the theory of synchrotron emission in the fast cooling regime can account for a wide range of spectral shapes. In particular, the magnetic field, which decays behind the shock front, brings enough flexibility to the theory to explain the majority of gamma-ray burst spectra even in the parameter-free fast cooling regime. Also, we discuss whether location of the peak in observed spectral energy distributions of gamma-ray bursts and active galactic nuclei can be made consistent with predictions of diffusive shock acceleration theory, and find that the answer is negative. This result is a strong indication that a particle injection mechanism, other than the standard shock acceleration, works in relativistic shocks.

description: Tobacco causes genetic damage associated with increased risk of oral cancer. Tobacco induces genetic aberrations and micronucleus assay is a great biomarker to study the effect of tobacco in human population .The analysis of micronuclei in the buccal mucosal cells has been shown to be a sensitive method for monitoring genetic damage in human population. The objective of my work is to compare the number of micronuclei in smokers and non-smokers and also evaluates the number of micronuclei in relation to age, frequency, duration, and sex. A total number of 60 subjects were taken for micronucleus assay. The samples were taken from the buccal mucosal cells are smeared on the pre cleaned slide and slides are stained with May-Grunwald and Giemsa stains and then different micronucleus anomalities will be studied under the microscope. We observed more micronuclei number in older age as compared younger age in each study group. Besides, damage in the mucosa increases with the years of smoking. It is found that the group with increased frequency of smoking shows more micronuclei. We also found that micronuclei count is seen more in females as compared to male, which clearly indicates that chewers are at high risk for developing oral cancer.

description: We report magnetization, specific heat, muon spin rotation and Na NMR measurements on the S=3/2 rhombohedrally stacked Heisenberg antiferromagnet NaCrO2. This compound appears to be an ideal candidate for the study of triangular Heisenberg antiferromagnets with very weak interlayer coupling. While specific heat and magnetization measurements indicate the occurrence of a transition in the range 40-46 K, both muon spin rotation and NMR reveal a fluctuating regime extending well below T_c, with a peak of relaxation rate 1/T1 around 30 K. This novel finding is discussed within the context of excitations in the triangular Heisenberg antiferromagnets.

description: Synchrony of neuronal ensembles is believed to facilitate information exchange among cortical regions in the human brain. Recently, it has been observed that distant brain areas which are not directly connected by neural links also experience synchronization. Such synchronization between remote regions is sometimes due to the presence of a mediating region connecting them, e.g., \textit{the thalamus}. The underlying network structure of this phenomenon is star-like and motivates us to study the \textit{remote synchronization} of Kuramoto oscillators, {modeling neural dynamics}, coupled by a directed star network, for which peripheral oscillators get phase synchronized, remaining the accommodating central mediator at a different phase. We show that the symmetry of the coupling strengths of the outgoing links from the central oscillator plays a crucial role in enabling stable remote synchronization. We also consider the case when there is a phase shift in the model which results from synaptic and conduction delays. Sufficient conditions on the coupling strengths are obtained to ensure the stability of remotely synchronized states. To validate our obtained results, numerical simulations are also performed.

description: The libraries generated by high-throughput single cell RNA-sequencing platforms such as the Chromium from 10x Genomics require considerable amounts of sequencing, typically due to the large number of cells. The ability to use this data to address biological questions is directly impacted by the quality of the sequence data. Here we have compared the performance of the Illumina NextSeq 500 and NovaSeq 6000 against the BGI MGISEQ-2000 platform using identical Single Cell 3’ libraries consisting of over 70,000 cells. Our results demonstrate a highly comparable performance between the NovaSeq 6000 and MGISEQ-2000 in sequencing quality, in addition to cell, UMI, and gene detection. However, compared with the NextSeq 500, the MGISEQ-2000 platform performs consistently better, identifying more cells, genes, and UMIs at equalized read depth. We were able to call an additional 1,065,659 SNPs from sequence data generated by the BGI platform, enabling an additional 14% of cells to be assigned to the correct donor from a multiplexed library. However, both the NextSeq 500 and MGISEQ-2000 detected similar frequencies of gRNAs from a pooled CRISPR single cell screen. Our study provides a benchmark for high capacity sequencing platforms applied to high-throughput single cell RNA-seq libraries.

The stellar mass - physical effective radius relation for dwarf galaxies in low-density environments

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: The scaling relation between stellar mass ($M_{*}$) and physical effective radius ($r_{e}$) has been well-studied using wide spectroscopic surveys. However, these surveys suffer from severe surface brightness incompleteness in the dwarf galaxy regime, where the relation is poorly constrained. In this study, I use a Bayesian empirical model to constrain the power-law exponent $β$ of the $M_{*}$-$r_{e}$ relation for late-type dwarfs ($10^{7}$$\leq$$M_{*}$/$M_{\odot}$$\leq$$10^{9}$) using a sample of 188 isolated low surface brightness (LSB) galaxies, accounting for observational incompleteness. Surprisingly, the best-fitting model ($β$=0.40$\pm$0.07) indicates that the relation is significantly steeper than would be expected from extrapolating canonical models into the dwarf galaxy regime. Nevertheless, the best fitting $M_{*}$-$r_{e}$ relation closely follows the distribution of known dwarf galaxies. These results indicate that extrapolated canonical models over-predict the number of large dwarf (i.e. LSB) galaxies, including ultra-diffuse galaxies (UDGs), explaining why they are over-produced by some semi-analytic models. The best-fitting model also constrains the power-law exponent of the physical size distribution of UDGs to $n\mathrm{[dex^{-1}]}\propto$$~r_{e}^{3.54\pm0.33}$, consistent to within 1$σ$ of the corresponding value in cluster environments and with the theoretical scenario in which UDGs occupy the high-spin tail of the normal dwarf galaxy population.

description: In this paper, we focus on studying the effects of various image operations on sensor fingerprint camera identification. It is known that artifacts in the image processing pipeline, such as pixel defects or unevenness of the responses in the CCD array as well black current noise leave telltale footprints. Nowadays, camera identification based on the analysis of these artifacts is a well established technology for linking an image to a specific camera. The sensor fingerprint is estimated from images taken from a device. A similarity measure is deployed in order to associate an image with the camera. However, when the images used in the sensor fingerprint estimation have been processed using e.g. gamma correction, contrast enhancement, histogram equalization or white balance, the properties of the detection statistic change, hence affecting fingerprint detection. In this paper we study this effect experimentally, towards quantifying the robustness of fingerprint detection in the presence of image processing operations.

description: We construct explicit rate-one, full-diversity, geometrically dense matrix lattices with large, non-vanishing determinants (NVD) for four transmit antenna multiple-input single-output (MISO) space-time (ST) applications. The constructions are based on the theory of rings of algebraic integers and related subrings of the Hamiltonian quaternions and can be extended to a larger number of Tx antennas. The usage of ideals guarantees a non-vanishing determinant larger than one and an easy way to present the exact proofs for the minimum determinants. The idea of finding denser sublattices within a given division algebra is then generalized to a multiple-input multiple-output (MIMO) case with an arbitrary number of Tx antennas by using the theory of cyclic division algebras (CDA) and maximal orders. It is also shown that the explicit constructions in this paper all have a simple decoding method based on sphere decoding. Related to the decoding complexity, the notion of sensitivity is introduced, and experimental evidence indicating a connection between sensitivity, decoding complexity and performance is provided. Simulations in a quasi-static Rayleigh fading channel show that our dense quaternionic constructions outperform both the earlier rectangular lattices and the rotated ABBA lattice as well as the DAST lattice. We also show that our quaternionic lattice is better than the DAST lattice in terms of the diversity-multiplexing gain tradeoff.

description: We have analyzed ALMA Cycle 5 data in Band 4 toward three low-mass young stellar objects (YSOs), IRAS 03235+3004 (hereafter IRAS 03235), IRAS 03245+3002 (IRAS 03245), and IRAS 03271+3013 (IRAS 03271), in the Perseus region. The HC$_{3}$N ($J=16-15$; $E_{\rm {up}}/k = 59.4$ K) line has been detected in all of the target sources, while four CH$_{3}$OH lines ($E_{\rm {up}}/k = 15.4-36.3$ K) have been detected only in IRAS 03245. Sizes of the HC$_{3}$N distributions ($\sim 2930-3230$ au) in IRAS 03235 and IRAS 03245 are similar to those of the carbon-chain species in the warm carbon chain chemistry (WCCC) source L1527. The size of the CH$_{3}$OH emission in IRAS 03245 is $\sim 1760$ au, which is slightly smaller than that of HC$_{3}$N in this source. We compare the CH$_{3}$OH/HC$_{3}$N abundance ratios observed in these sources with predictions of chemical models. We confirm that the observed ratio in IRAS 03245 agrees with the modeled values at temperatures around 30--35 K, which supports the HC$_{3}$N formation by the WCCC mechanism. In this temperature range, CH$_{3}$OH does not thermally desorb from dust grains. Non-thermal desorption mechanisms or gas-phase formation of CH$_{3}$OH seem to work efficiently around IRAS 03245. The fact that IRAS 03245 has the highest bolometric luminosity among the target sources seems to support these mechanisms, in particular the non-thermal desorption mechanisms.

description: Η συναλλαγματική ισοτιμία αποτελεί μια από τις βασικότερες μεταβλητές και ταυτόχρονα ένα από τα σημαντικότερα μέσα άσκησης πολιτικής μιας χώρας που χαρακτηρίζεται ως μια ανοιχτή οικονομία. Πράγματι, είναι ένας από τους κρισιμότερους παράγοντες που επηρεάζουν το διεθνές νομισματικό σύστημα. Σκοπός της παρούσας διπλωματικής εργασίας είναι διττός: από τη μια να παρουσιάσει τα βασικά θεωρητικά υποδείγματα προσδιορισμού των συναλλαγματικών ισοτιμιών που συναντάμε στην αντίστοιχη βιβλιογραφία και από την άλλη να προβεί σε εμπειρικό έλεγχο αυτών των θεωρητικών υποδειγμάτων με στόχο τον εντοπισμό των βασικότερων προσδιοριστικών παραγόντων των συναλλαγματικών ισοτιμιών. Στο πρώτο μέρος της εργασίας παρουσιάζουμε τη θεωρία που συναντάται στην ανάλυση των συναλλαγματικών ισοτιμιών ενώ το δεύτερο μέρος αφιερώνεται στην εμπειρική διερεύνηση των προσδιοριστικών παραγόντων τους. Πιο συγκεκριμένα το υπόδειγμα που χρησιμοποιούμε προσπαθεί να διερευνήσει το κατά πόσο το εργατικό κόστος προσδιορίζει την ανταγωνιστικότητα μιας χώρας. Η ανάλυση αφορά τις ΗΠΑ και τη Μεγάλη Βρετανία, οι οποίες είναι δυο χώρες που μοιράζονται πολλές κοινές οικονομικές, θεσμικές και πολιτικές αξίες και αποτελούν ταυτόχρονα δυο μεγάλες οικονομίες στην παγκόσμια σκηνή. Η μεθοδολογία που χρησιμοποιείται είναι η ARDL. Τα αποτελέσματα μας επιβεβαιώνουν ότι το μοναδιαίο κόστος εργασίας παίζει καθοριστικό ρολό στον προσδιορισμό των συναλλαγματικών ισοτιμιών και κατ' επέκταση στην ανταγωνιστικότητα των δυο υπό εξέταση οικονομιών.
description: The exchange rate is one of the main variables and simultaneously one of the most important policy instruments of a country that is characterized as an open economy. Moreover It is one of the most critical factors affecting the international monetary system. The purpose of this paper is twofold: firstly to describe the basic theoretical model in order to show the basic theoretical models of exchange rates found in the corresponding literature and secondly to put these theoretical models under empirical testing in order to identify the main determinants of exchange rates. More specifically the analysis is divided in two parts. In the first part we present the mainstream theory used in the analysis of exchange rates and on the second part we put these models under a consideration. More specifically, the model that we use is trying to investigate whether labor cost determines the competitiveness of a country. The analysis relates to the USA and Great Britain, which are two countries share many common economic, institutional and political values and are both two big economies. During our analysis we use the ARDL method. And the results confirm the absolute advantage ( unit labor cost affects the exchange rates)

description: In this work we characterise the properties of the object SDSS J020536.84-081424.7, an extended nebular region with projected extension of $14 \times 14$ kpc$^{2}$ in the line of sight of the ETG Mrk 1172, using unprecedented spectroscopic data from MUSE. We perform a spatially resolved stellar population synthesis and estimate the stellar mass for both Mrk 1172 ($1 \times 10^{11} M_{\odot}$) and our object of study ($3 \times 10^{9} M_{\odot}$). While the stellar content of Mrk 1172 is dominated by an old ($\sim 10$ Gyr) stellar population, the extended nebular emission has its light dominated by young to intermediate age populations (from $\sim 100$ Myr to $\sim 1$ Gyr) and presents strong emission lines such as: H$β$, [O III] $λλ$4959,5007, H$α$, [N II] $λλ$6549,6585 and [S II] $λλ$6717,6732. Using these emission lines we find that it is metal-poor (with $Z \sim$ 1/3 $Z_{\odot}$, comparable to the LMC) and is actively forming stars ($0.70$ M$_{\odot}$ yr$^{-1}$), especially in a few bright clumpy knots that are readily visible in H$α$. The object has an ionised gas mass $\geq 3.8 \times 10^{5}$ M$_{\odot}$. Moreover, the motion of the gas is well described by a gas in circular orbit in the plane of a disk and is being affected by interaction with Mrk 1172. We conclude that SDSS J020536.84-081424.7 is most likely a dwarf irregular galaxy (dIGal).

description: Preliminary results concerning the time evolution of strongly exited SU(2) Bogomolny-Prasad-Sommerfield (BPS) magnetic monopoles have been published in Phys. Rev. Lett. 92, 151801 (2004). The behavior of these dynamical magnetic monopoles was investigated by means of numerical simulations in the four dimensional Minkowski spacetime. The developed code incorporates both the techniques of conformal compactification and that of the hyperboloidal initial value problem. Our primary aim here is to provide a detailed account on the methods and results of the investigations reported in Phys. Rev. Lett. 92, 151801 (2004). In addition, some important new results, which go much beyond the scope of these early studies, are also presented. In particular, to be able to distinguish linear and non-linear effects, evolutions of monopoles deformed by various excitations, including both very small and extra large energy excitation, are investigated. In addition, a detailed account is provided on the spacetime dependence of the basic variables, as well as, that of the other physically significant dynamical qualities such as the energy and energy current densities, the radial and angular pressures and the magnetic charge density. A careful comprehensive study of the associated energy transfers and energy balances is also included.

description: We investigate whether the sky rate of Fast Radio Bursts depends on Galactic latitude using the first catalog of Fast Radio Bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project. We first select CHIME/FRB events above a specified sensitivity threshold in consideration of the radiometer equation, and then compare these detections with the expected cumulative time-weighted exposure using Anderson-Darling and Kolmogrov-Smirnov tests. These tests are consistent with the null hypothesis that FRBs are distributed without Galactic latitude dependence ($p$-values distributed from 0.05 to 0.99, depending on completeness threshold). Additionally, we compare rates in intermediate latitudes ($|b| < 15^\circ$) with high latitudes using a Bayesian framework, treating the question as a biased coin-flipping experiment -- again for a range of completeness thresholds. In these tests the isotropic model is significantly favored (Bayes factors ranging from 3.3 to 14.2). Our results are consistent with FRBs originating from an isotropic population of extragalactic sources.

description: Στην εν λόγω διπλωματική εργασία διερευνάται το αν η αθλητική δημοσιογραφία ακολουθεί τις πρακτικές της αντιπαραθετικής ή της ειρηνευτικής δημοσιογραφίας, κατά την προβολή των αθλητικών συγκρούσεων στην Ελλάδα. Η διπλωματική εργασία είναι χωρισμένη σε δύο μέρη. Το πρώτο περιλαμβάνει μία θεωρητική προσέγγιση του θέματος, βάσει της υπάρχουσας βιβλιογραφίας, για την ειρηνευτική δημοσιογραφία, τα κοινωνικά αίτια του χουλιγκανισμού και μία ιστορική προσέγγιση αυτού, περιστατικά αθλητικής βίας στην Ελλάδα, την αθλητική δημοσιογραφία στην Ευρώπη και στην Ελλάδα, ενώ περιγράφεται και η θεωρία της πλαισίωσης. Το δεύτερο μέρος περιλαμβάνει την έρευνα. Εξετάζεται η σύγκρουση μεταξύ του προέδρου της Π.Α.Ε. (Ποδοσφαιρική Ανώνυμη Εταιρία) Ολυμπιακός, Βαγγέλη Μαρινάκη, και του προέδρου της Π.Α.Ε. Α.Ε.Κ., Δημήτρη Μελισσανίδη. Η μεθοδολογία που ακολουθείται είναι αυτή της μελέτης περίπτωσης (case study) και αφορά σε ένα περιστατικό που αποτέλεσε την αφορμή για να φουντώσει η σύγκρουση και το πώς αυτό απεικονίζεται στα μεγαλύτερα αθλητικά sites. Στη συνέχεια, ορίζονται οι μεταβλητές με βάση τις οποίες διεξάγεται η έρευνα και γίνεται η εξαγωγή των συμπερασμάτων που απαντά στα ερωτήματα που έχουν τεθεί. Τελικά, αυτό που διαπιστώνεται είναι ότι, αν και εντοπίζονται επιμέρους διαφορές που έχουν να κάνουν με τη φύση της εκάστοτε ιστοσελίδας και κυρίως το αν και πού πρόσκειται η καθεμιά από αυτές, σε γενικές γραμμές, ο τρόπος απεικόνισης των αθλητικών συγκρούσεων είναι μη ειρηνευτικός (αντιπαραθετικός).
description: This study investigates whether the sports journalism follows the practices of war or peace journalism, when viewing conflicts about sports in Greece. The thesis is divided into two parts. The first involves a theoretical approach, based on existing literature on peace journalism, on the social causes of hooliganism and its historical approach, on incidents of sports violence in Greece, on sports journalism in Europe and in Greece and a description of the theory of the framing. The second part includes the research, which examines the conflict between the president of FC Olympiakos, Vangelis Marinakis, and the president of FC AEK, Dimitris Melissanidis. The methodology that is used is the case study and relates to an incident which gave rise to the conflict flared up and how this is reflected in major Greek sports sites. Then, we set the variables on which the research is conducted and we export the conclusions that answer to the questions that are set. Ultimately, what is found is that, although there are some differences between the presentations of the conflict on the Greek sports sites, which have to do with the nature of each site and especially whether and where is each of them sympathetic, the general imaging mode of sports conflicts are not peacekeeping (war).
