description: Η παρούσα Διπλωματική εργασία διαπραγματεύεται το θέμα της ευθανασίας (είδη, αίτια, συνέπειες, προσέγγιση του ζητήματος) και την παρηγορητική φροντίδα που προσφέρεται σε πάσχοντες από ανίατες ασθένειες, με ιδιαίτερη αναφορά στη δράση και στις θέσεις της Ορθόδοξης και της Ρωμαιοκαθολικής Εκκλησίας. Το πρώτο μέρος της Διπλωματικής εντάσσει την ευθανασία στο πεδίο της Βιοηθικής, ενός κλάδου που ασχολείται με θέματα ιατρικής φύσεως, που συνδέονται με την ανάγκη προστασίας της προσωπικότητας του ανθρώπου. Ακόμη, αναφέρονται ορισμένες προσεγγίσεις της ευθανασίας, μια ιστορική αναδρομή της και τα είδη της. Επίσης, γίνεται αναφορά στην έννοια του «καλού θανάτου». Το δεύτερο μέρος αναφέρεται στην παρηγορητική φροντίδα (ορισμός, στόχος, ήθος, διαδικασία και σημασία). Το τρίτο μέρος περιγράφει πως αντιμετωπίζει το θέμα της ευθανασίας η Ορθόδοξη Εκκλησία (θέσεις, εντοπισμός αιτίων και συνεπειών, προτάσεις, εκδηλώσεις αγάπης σχετιζόμενες με την παρηγορητική φροντίδα). Το τέταρτο μέρος περιγράφει την αντιμετώπιση του θέματος της ευθανασίας από τη Ρωμαιοκαθολική Εκκλησία (θέσεις, άσκηση παρηγορητικής φροντίδας, σχετικές ενέργειες του Βατικανού). Το επίμετρο περιλαμβάνει τις θέσεις που διατύπωσε η Αγία και Μεγάλη Σύνοδος της Ορθόδοξης Εκκλησίας του 2016 για βιοηθικά θέματα
description: The present thesis of Msc study negotiates the subject of euthanasia (the species, the causes, the consequences, the approach to the subject) and the palliative care offered to sufferers of incurable diseases. It makes a particular reference to the action and the positions of the Orthodox and the Roman Catholic Church. The first part of the thesis encompasses the euthanasia in the field of the Bioethics, a discipline which studies medical subjects, which are connected with the need to preserve the human personality. There are also some approaches to euthanasia, a historical retrospection and its species. Also, there is a reference to the concept of the "good death". The second part refers to the palliative care (a definition, the purpose, the morals, the process and the importance). The third part describes the way of approaching the subject of euthanasia from the Orthodox Church (the positions, the identification of the causes and the consequences, some suggestions, the charity related to the palliative care). The fourth part describes the approach to the subject of euthanasia by the Roman Catholic Church (the positions, the palliative care, Vatican’s related activities). The appendix includes the positions formulated by the Holy and Great Synod of the Orthodox Church in 2016 about bioethical subjects

description: In this paper we present a formal description of PROSA, a P2P resource management system heavily inspired by social networks. Social networks have been deeply studied in the last two decades in order to understand how communities of people arise and grow. It is a widely known result that networks of social relationships usually evolves to small-worlds, i.e. networks where nodes are strongly connected to neighbours and separated from all other nodes by a small amount of hops. This work shows that algorithms implemented into PROSA allow to obtain an efficient small-world P2P network.

description: In 1972, Zinn, Newell, & Gibson (ZNG) published a list of 156 candidate "UV-bright" stars they had found in 27 Galactic globular clusters (GCs), based on photographs in the U and V bands. UV-bright stars lie above the horizontal branch (HB) and blueward of the asymptotic-giant branch (AGB) and red-giant branch in the clusters' color-magnitude diagrams. They are in rapid evolutionary phases--if they are members and not unrelated bright foreground stars. The ZNG list has inspired numerous follow-up studies, aimed at understanding late stages of stellar evolution. However, the ZNG candidates were presented only in finding charts, and celestial coordinates were not given. Using my own collection of CCD frames in u and V, I have identified all of the ZNG objects, and have assembled their coordinates, parallaxes, and proper motions from the recent Gaia Early Data Release 3 (EDR3). Based on the Gaia astrometry, I have determined which objects are probable cluster members (45% of the sample). For the members, using photometry from EDR3, I have assigned the stars to various evolutionary stages, including luminous post-AGB stars, and stars above the HB. I point out several ZNG stars of special interest that have still, to my knowledge, never been studied in detail. This study is an adjunct to a forthcoming survey of the Galactic GCs in the uBVI photometric system, designed for detection of low-gravity stars with large Balmer discontinuities.

description: The object of this essay is the study of the ritual of Arkteia, in the context of the festival of Brauronia, and it’s relation to the social position of women in 5th century B. C. Athens. Specifically, the ritual is examined as a rite of passage and coming of age ritual, which allows the girls that participate in it to be incorporated into the society of the time. The study uses references from the academical area of ritual theory, gender studies as well as material from studies done on the social position of women in Ancient Greece. Biological references are used regarding human behaviour, in the effort of finding the biological significance of the ritual. Lastly, a comparison of the ritual of Arkteia as a female rite of passage, is made in reference to the ritual of Koureia as an equivalent male ritual. The goal is the connection of the ritual of Arkteia with the social status of women of the time as well as the establishment of elements that influence this status

description: Today the B-factories BaBar and Belle have accumulated largest samples of tau-tau events and are competing to be called tau-factories. Among the problems to be tested and measurements to be done by BaBar and Belle are check of CP and CPT invariance in tau decays, measurement of strange and non-strange spectral functions, extraction of mass of strange quark and |V_us|, searches for lepton flavor violation processes. In this paper, the latest results in tau physics by these two experiments and measurements to be done within next few years are reviewed.

description: We investigate the stability against inhomogeneous perturbations and the appearance of ghost modes in Gauss-Bonnet gravitational theories with a non-minimally coupled scalar field, which can be regarded as either the dilaton or a compactification modulus in the context of string theory. Through cosmological linear perturbations we extract four no-ghost and two sub-luminal constraint equations, written in terms of background quantities, which must be satisfied for consistency. We also argue that, for a general action with quadratic Riemann invariants, homogeneous and inhomogeneous perturbations are, in general, inequivalent, and that attractors in the phase space can have ghosts. These results are then generalized to a two-field configuration. Single-field models as candidates for dark energy are explored numerically and severe bounds on the parameter space of initial conditions are placed. A number of cases proposed in the literature are tested and most of them are found to be unstable or observationally unviable.

description: We report a direct observation of dramatic mass transport due to 1.5 MeV Au2+ ion impact on isolated Au nanostructures of an average size 7.6 nm and a height 6.9 nm that are deposited on Si (111) substrate under high flux (3.2x10^10 to 6.3x10^12 ions cm-2 s-1) conditions. The mass transport from nanostructures found to extend up to a distance of about 60 nm into the substrate, much beyond their size. This forward mass transport is compared with the recoil implantation profiles using SRIM simulation. The observed anomalies with theory and simulations are discussed. At a given energy, the incident flux plays a major role in mass transport and its re-distribution. The mass transport is explained on the basis of thermal effects and creation of rapid diffusion paths at nano-scale regime during the course of ion irradiation. The unusual mass transport is found to be associated with the formation of gold silicide nanoalloys at sub-surfaces. The complexity of the ion-nanostructure interaction process has been discussed with a direct observation of melting (in the form of spherical fragments on the surface) phenomena. The transmission electron microscopy, scanning transmission electron microscopy and Rutherford backscattering spectroscopy methods have been used.

description: The dominant physical formation mechanism(s) for ultra-diffuse galaxies (UDGs) is still poorly understood. Here, we combine new, deep imaging from the Jeanne Rich Telescope with deep integral field spectroscopy from the Keck II telescope to investigate the formation of UDG1137+16 (dw1137+16). Our new analyses confirm both its environmental association with the low density UGC 6594 group, along with its large size of 3.3 kpc and status as a UDG. The new imaging reveals two distinct stellar components for UDG1137+16, indicating that a central stellar body is surrounded by an outer stellar envelope undergoing tidal interaction. Both the components have approximately similar stellar masses. From our integral field spectroscopy we measure a stellar velocity dispersion within the half-light radius (15 $\pm$ 4 $\mathrm{km\ s^{-1}}$) and find that UDG1137+16 is similar to some other UDGs in that it is likely dark matter dominated. Incorporating literature measurements, we also examine the current state of UDG observational kinematics. Placing these data on the central stellar velocity dispersion -- stellar mass relation, we suggest there is little evidence for UDG1137+16 being created through a strong tidal interaction. Finally, we investigate the constraining power current dynamical mass estimates (from stellar and globular cluster velocity dispersions) have on the total halo mass of UDGs. As most are measured within the half-light radius, they are unable to accurately constrain UDG total halo masses.

Unified First Law and Thermodynamics of Apparent Horizon in FRW Universe

description: In this paper we revisit the relation between the Friedmann equations and the first law of thermodynamics. We find that the unified first law firstly proposed by Hayward to treat the "outer"trapping horizon of dynamical black hole can be used to the apparent horizon (a kind of "inner" trapping horizon in the context of the FRW cosmology) of the FRW universe. We discuss three kinds of gravity theorties: Einstein theory, Lovelock thoery and scalar-tensor theory. In Einstein theory, the first law of thermodynamics is always satisfied on the apparent horizon. In Lovelock theory, treating the higher derivative terms as an effective energy-momentum tensor, we find that this method can give the same entropy formula for the apparent horizon as that of black hole horizon. This implies that the Clausius relation holds for the Lovelock theory. In scalar-tensor gravity, we find, by using the same procedure, the Clausius relation no longer holds. This indicates that the apparent horizon of FRW universe in the scalar-tensor gravity corresponds to a system of non-equilibrium thermodynamics. We show this point by using the method developed recently by Eling {\it et al.} for dealing with the $f(R)$ gravity.

description: A chiral photonic interface is a quantum system that has different probabilities for emitting photons to the left and right. An on-chip compatible chiral interface is attractive for both fundamental studies of light-matter interactions and applications to quantum information processing. We propose such a chiral interface based on superconducting circuits, which has wide bandwidth, rich tunability, and high tolerance to fabrication variations. The proposed interface consists of a core that uses Cooper-pair boxes (CPBs) to break time-reversal symmetry, and two superconducting transmons that connect the core to a waveguide in the manner reminiscent of a ``giant atom.'' The transmons form a state decoupled from the core, akin to dark states of atomic physics, rendering the whole interface insensitive to the CPB charge noise. The proposed interface can be extended to realize a broadband fully passive on-chip circulator for microwave photons.

description: Product proliferation is a strategy of product space filling over time. However, product proliferation can be undertaken in two main ways, including densification (proliferating products within existing product lines) and expansion (proliferating by expanding into new product lines). Despite the fact that many firms engage in product proliferation activities, the outcomes are not yet clearly understood. This is potentially due to gaps in extant literature around an incomplete assessment of the product proliferation construct, which is multidimensional, inappropriate and static measurement of firm proliferation efforts, and a lack of research into what resources might support or damage product proliferation efforts (the study of boundary conditions). This research addresses these issues by developing product proliferation as a multidimensional construct, developing measurements to capture the dynamic changes in firm’s product portfolio, and exploring the impact of three important boundary conditions. The boundary conditions studied are R&D efforts, marketing efforts, and scopification (the number of new brand/product lines a firm has expanded into in a particular time period). Longitudinal data from 2010 to 2015 were collected, including 78 cases from the automotive, motorcycle, and fragrance industries. The data was analyzed using multilevel modeling, to enable a time series assessment of the findings. The results reveal that the product proliferation-firm performance relationship is complex, varying in terms of the different dimensions and according to the level of different boundary conditions. Thus, management may utilize the research findings by managing their R&D efforts, marketing efforts, and scopification according to each type of product space filling approach, and academics may utilize the findings of this research in many aspects (e.g. measurements, new facet of product proliferation) to further develop product proliferation theory.

description: Following Feigin and Fuchs, we compute the first cohomology of the Lie superalgebra $\mathcal{K}(1)$ of contact vector fields on the (1,1)-dimensional real superspace with coefficients in the superspace of linear differential operators acting on the superspaces of weighted densities. We also compute the same, but $\mathfrak{osp}(1|2)$-relative, cohomology. We explicitly give 1-cocycles spanning these cohomology. We classify generic formal $\mathfrak{osp}(1|2)$-trivial deformations of the $\mathcal{K}(1)$-module structure on the superspaces of symbols of differential operators. We prove that any generic formal $\mathfrak{osp}(1|2)$-trivial deformation of this $\mathcal{K}(1)$-module is equivalent to a polynomial one of degree $\leq4$. This work is the simplest superization of a result by Bouarroudj [On $\mathfrak{sl}$(2)-relative cohomology of the Lie algebra of vector fields and differential operators, J. Nonlinear Math. Phys., no.1, (2007), 112--127]. Further superizations correspond to $\mathfrak{osp}(N|2)$-relative cohomology of the Lie superalgebras of contact vector fields on $1|N$-dimensional superspace.

Growing Supermassive Black Holes by Chaotic Accretion

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We consider the problem of growing the largest supermassive black holes from stellar--mass seeds at high redshift. Rapid growth without violating the Eddington limit requires that most mass is gained while the hole has a low spin and thus a low radiative accretion efficiency. If, as was formerly thought, the black--hole spin aligns very rapidly with the accretion flow, even a randomly--oriented sequence of accretion events would all spin up the hole and prevent rapid mass growth. However, using a recent result that the Bardeen--Petterson effect causes {\it counter}alignment of hole and disc spins under certain conditions, we show that holes can grow rapidly in mass if they acquire most of it in a sequence of randomly oriented accretion episodes whose angular momenta $J_d$ are no larger than the hole's angular momentum $J_h$. Ultimately the hole has total angular momentum comparable with the last accretion episode. This points to a picture in which the accretion is chaotic on a lengthscale of order the disc size, that is $\la 0.1$ pc.

We resort to umbrella sampling to resolve the asymptotic decay of P(f) for large f, and determine P(f) down to values of order 10^{-45} for ordered and disordered systems in two and three dimensions. Our findings unambiguously show that, in the ensemble approach, the force distributions decay much faster than exponentially: P(f) ~ exp(-f^α), with alpha \approx 2.0 for 2D systems, and alpha \approx 1.7 for 3D systems.

description: We consider some flat space theories for spin 2 gravitons, with less invariance than full diffeomorphisms. For the massless case, classical stability and absence of ghosts require invariance under transverse diffeomorphisms (TDiff). Generic TDiff invariant theories contain a propagating scalar, which disappears if the symmetry is enhanced in one of two ways. One possibility is to consider full diffeomorphisms (Diff). The other (which we denote WTDiff) adds a Weyl symmetry, by which the Lagrangian becomes independent of the trace. The first possibility corresponds to General Relativity, whereas the second corresponds to "unimodular" gravity (in a certain gauge). Phenomenologically, both options are equally acceptable. For massive gravitons, the situation is more restrictive. Up to field redefinitions, classical stability and absence of ghosts lead directly to the standard Fierz-Pauli Lagrangian. In this sense, the WTDiff theory is more rigid against deformations than linearized GR, since a mass term cannot be added without provoking the appearance of ghosts.
[NGI Explorers | Martin Serrano] A Perspective towards a New Normality and Working Conditions following COVID-19
Creators: name: Serrano, Martin

Year: 2020

description: After the first outbreak on COVID-19 in China, the spread to Europe and other continents, the WHO’s pandemic declaration, the already long duration of confinement conditions in some countries and the unknown effects on everybody’s life, we are yet to see the long effects of the pandemic evolution. Society is yet over studying and analysing what will be the economic and social consequences in the longer term globally. One thing is certain, the biggest impact so far is in people’s behaviour. It is too early yet to talk about the psychology of people after COVID- 19 but one of the clearest consequences is the trust that people have lost in relation to health conditions, not only in their closed circle of individuals, but also in others surrounding them. People are thinking now, about how many of those individuals around them are healthy? or who has not worried about going outside and thinking twice if it is safe (healthy), to use the public transport which is shared with other individuals or going into a place with another group of unknown people. Those questions may remain for a long time and certainly the worst of the pandemic effects is how society as a whole can trust each other to ensure good health. As a research and scientific community we are all committed to address the challenges of COVID-19, from the most complex aspect, which is to find a solution to also find contention methods or also generate best practices for living or also best practices to pass through the COVID-19 effects. A series of informative documents have been generated and knowing a lot of information has been published already. In this document we only focus on collecting experiences from people who usually worked in open office environments and from those who their main activity involves interacting with others, either in small meeting rooms and/or medium size group meetings or simply in office corridors, in labs, in a classroom and/or in general indoors locations. The document will describe some ideas but also some facts in a form of recommendations on how people can safely return to do their work after COVID-19 pandemic lockdown is lifted. This can be considered as a wish list of overall (general) and specific (particular) requirements that potentially can help to recover trust. It is possible some of these measures have already been implemented but if not they certainty will be relatively easy to implement and the main benefit of considering them is gaining trust to make people feel safe at work. Those activities and measures that need to be implemented shall be taken as methods to enable people to develop, not only new methods, but also to provide indirect psychological support for a new normal start in terms of work practices after the pandemic.

description: Machine learning approaches achieve high accuracy for text recognition and are therefore increasingly used for the transcription of handwritten historical sources. However, using machine learning in production requires a streamlined end-to-end pipeline that scales to the dataset size and a model that achieves high accuracy with few manual transcriptions. The correctness of the model results must also be verified. This paper describes our lessons learned developing, tuning and using the Occode end-to-end machine learning pipeline for transcribing 2.3 million handwritten occupation codes from the Norwegian 1950 population census. We achieve an accuracy of 97% for the automatically transcribed codes, and we send 3% of the codes for manual verification. We verify that the occupation code distribution found in our results matches the distribution found in our training data, which should be representative for the census as a whole. We believe our approach and lessons learned may be useful for other transcription projects that plan to use machine learning in production.

Εξετάστηκε η έννοια της αγάπης και ο τρόπος που εκείνη συλλαμβάνεται τόσο από τους ανθρώπους, όσο και από τον στοχαστή. Τονίστηκε ιδιαίτερα, πως τα όντα στην πλειονότητά τους δεν ενστερνίζονται ορθά την έννοια της αγάπης καθώς καθίστανται θύματα της σκέψης. Έγινε εκτενής αναφορά στη σκέψη και στον τρόπο που η ίδια δεσμεύει το ον και το τρέπει σε υποχείριο του φόβου σχετικά με τον χρόνο και τη ψυχολογική διάκρισή του σε παρόν – παρελθόν – μέλλον, στερώντας την ελευθερία του. Παράλληλά, ένα άλλο θέμα που θίχτηκε είναι η εμπειρία του στοχασμού μέσω της οποίας το ον δύναται να αποδεσμευτεί από ό,τι το καθιστά δέσμιο και ν’ ανηχθεί σ’έναν νέο χώρο μακριά από την σκέψη και το φορτίο της, όπου θα οδηγηθεί ελεύθερα στη θέαση της πραγματικής αγάπης
description: The purpose of this thesis was to study the concepts of love and experience of reflection in the thought of Jiddu Krishnamurti. Examined the concept of love and the way which it is captured by both people and thoughtful. It has been particularly emphasized that the majority of human beings do not properly embrace the concept of love because they become victims of thinking. An extensive reference has been made to the thought and the way which love binds the human being and turns it into a stooge of fear of time and his psychological discernment in the present – past – future, depriving his freedom. At the same time, another issue that is touched is the experience of reflection through which the being can be released from what makes it captive and new space away from thought, where it will be freely led to view of true love

description: Σκοπός της διατριβής ήταν η μελέτη της συνεισφοράς της θεωρίας της Αποξένωσης στην κριτική θεωρία του Μπερτολτ Μπρεχτ τόσο αναφορικά με την αισθητική του θεωρία όσο και σχετικά με την φιλοσοφική του σκέψη. Στη μελέτη αυτή κωδικοποιήθηκαν βασικές αρχές της μπρεχτικής σκέψης, εκθέτοντας τις μαρξιστικές αφετηρίες της όσο και τη δική της συμβολή στην εξέλιξη της αισθητικής θεωρίας του σοσιαλιστικού ρεαλισμού. Παρουσιάστηκαν θεμελιακές αρχές της αισθητικής θεωρίας που συγκροτούνται μέσα από μια περιδιάβαση μελετών, άρθρων, αλλά και της προσωπικής αλληλογραφίας και των ημερολογίων του Μπρεχτ, ενώ μέσα από την ίδια την παραγωγική δραστηριότητα του ίδιου αποπειράθηκε μια εξαγωγή ορισμένων συμπερασμάτων αναφορικά με την κριτική στάση του θεατή, την αποξένωση και τη γνωστική πληρότητα των προθέσεων και των συναισθηματικών αποκρίσεων του θεατρικού γεγονότος. Τέλος επιχειρήθηκε η μετατόπιση της θεωρίας αυτής στο πεδίο της πολιτικής σκέψης του Μπρεχτ, διαπιστώνοντας τις προεκτάσεις και τις συσχετίσεις που μπορούν να εντοπιστούν αναφορικά με την πολιτική κριτική σκέψη και πράξη
description: The aim of the present thesis was the study of the contribution of defamiliarization theory to the relationship of art and social reality in Bertolt Brecht’s cogitatio. In the present thesis, a thorough presentation of the fundamental principles of brechtian thought was attempted, starting from its Marxist origins and content. Composing the aesthetic principles of Brecht’s concerning the Epic theatre, the defamiliarization, Historization, Gestus and critical stance, through a wide range of bibliographic references of his: studies, articles, his personal correspondence, diaries of him, and even his critical and theatrical works, conclusions have been reached regarding the observer’s critical stance, defamiliarization as a mean to a political target and as a target itself, and the cognitive evaluation of intentions, and their manifestations in everyday life next to a sensational response. In conclusion, it was tried to reach a field of correlation with the political thought of Brecht’s, mainly, as for its extensions for a political critical stance and praxis

description: Results of theoretical calculations of ionization rates of Rb and Na Rydberg atoms by blackbody radiation (BBR) are presented. Calculations have been performed for nS, nP and nD states of Na and Rb, which are commonly used in a variety of experiments, at principal quantum numbers n=8-65 and at three ambient temperatures of 77, 300 and 600 K. A peculiarity of our calculations is that we take into account the contributions of BBR-induced redistribution of population between Rydberg states prior to photoionization and field ionization by extraction electric field pulses. The obtained results show that these phenomena affect both the magnitude of measured ionization rates and shapes of their dependencies on n. The calculated ionization rates are compared with the results of our earlier measurements of BBR-induced ionization rates of Na nS and nD Rydberg states with n=8-20 at 300 K. A good agreement for all states except nS with n>15 is observed. We also present the useful analytical formulae for quick estimation of BBR ionization rates of Rydberg atoms.

description: Decentralized training of deep learning models enables on-device learning over networks, as well as efficient scaling to large compute clusters. Experiments in earlier works reveal that, even in a data-center setup, decentralized training often suffers from the degradation in the quality of the model: the training and test performance of models trained in a decentralized fashion is in general worse than that of models trained in a centralized fashion, and this performance drop is impacted by parameters such as network size, communication topology and data partitioning. We identify the changing consensus distance between devices as a key parameter to explain the gap between centralized and decentralized training. We show in theory that when the training consensus distance is lower than a critical quantity, decentralized training converges as fast as the centralized counterpart. We empirically validate that the relation between generalization performance and consensus distance is consistent with this theoretical observation. Our empirical insights allow the principled design of better decentralized training schemes that mitigate the performance drop. To this end, we provide practical training guidelines and exemplify its effectiveness on the data-center setup as the important first step.

description: Place recognition is critical for both offline mapping and online localization. However, current single-sensor based place recognition still remains challenging in adverse conditions. In this paper, a heterogeneous measurements based framework is proposed for long-term place recognition, which retrieves the query radar scans from the existing lidar maps. To achieve this, a deep neural network is built with joint training in the learning stage, and then in the testing stage, shared embeddings of radar and lidar are extracted for heterogeneous place recognition. To validate the effectiveness of the proposed method, we conduct tests and generalization experiments on the multi-session public datasets compared to other competitive methods. The experimental results indicate that our model is able to perform multiple place recognitions: lidar-to-lidar, radar-to-radar and radar-to-lidar, while the learned model is trained only once. We also release the source code publicly: https://github.com/ZJUYH/radar-to-lidar-place-recognition.

VLBI Images of 49 Radio Supernovae in Arp 220

description: We have used a Very Long Baseline Interferometry (VLBI) array at 18cm wavelength to image the nucleus of the luminous IR galaxy Arp 220 at ~1 pc linear resolution, and with very high sensitivity. The resulting map has an rms of 5.5 microJy/beam, and careful image analysis results in 49 confirmed point sources ranging in flux density from 1.2 mJy down to ~60 microJy. Comparison with high sensitivity data from 12 months earlier reveals at least four new sources. The favored interpretation of these sources is that they are radio supernovae, and if all new supernovae are detectable at this sensitivity, a resulting estimate of the supernova rate in the Arp 220 system is 4 +/- 2 per year. The implied star formation rate is sufficient to power the entire observed far-infrared luminosity of the galaxy. The two nuclei of Arp 220 exhibit striking similarities in their radio properties, though the western nucleus is more compact, and appears to be ~3 times more luminous than the eastern nucleus. There are also some puzzling differences, and differential free-free absorption, synchrotron aging and expansion losses may all be playing a role. Comparison with the nearby starburst galaxy M82 supports the hypothesis that the activity in Arp 220 is essentially a scaled-up version of that in M82.

description: Στη συγκεκριμένη διπλωματική μεταπτυχιακή εργασία, πραγματοποιείται μία προσπάθεια του να εξετασθεί το σύγχρονο φαινόμενο της εξάρτησης από το διαδίκτυο. Ειδικότερα, σκοπός της έρευνας είναι η ανάδειξη των ρόλων των θεραπευτικών συμβούλων στα προγράμματα απεξάρτησης ή στις δομές συμβουλευτικής για το διαδίκτυο στην Ελλάδα. Τους επιμέρους στόχους αποτέλεσαν η παρουσίαση των επιστημονικών μεθόδων και τεχνικών που χρησιμοποιούν οι επαγγελματίες αλλά και οι τρόποι παρέμβασης κατά το στάδιο της «υποτροπής» του ατόμου. Για το λόγο αυτό, πραγματοποιήθηκε ποιοτική μελέτη η οποία διεξήχθη μέσω ατομικών προσωπικών συνεντεύξεων με ημιδομημένες ερωτήσεις. Στη μελέτη συμμετείχαν 10 συνολικά θεραπευτικοί σύμβουλοι - εργαζόμενοι σε δομές συμβουλευτικής ή απεξάρτησης από το διαδίκτυο. Τα αποτελέσματα της έρευνας ανέδειξαν τη δυσκολία των θεραπευτικών συμβούλων να ορίσουν την εξάρτηση από το διαδίκτυο, τη πληθώρα ρόλων και τεχνικών αλλά και τη τάση για μη χρήση της έννοιας «υποτροπή» στο συγκεκριμένο τομέα. Τέλος, τα ευρήματα προσφέρουν προτάσεις και ιδέες για μελλοντικές μελέτες που θα φανούν χρήσιμες τόσο για τη πρόληψη και αντιμετώπιση του φαινομένου όσο και για την ενημέρωση της οικογένειας και των αρμόδιων φορέων
description: In this diploma thesis, is an attempt to examine the modern phenomenon of addiction from the internet. More specifically, aim of research is designation of the role of therapeutic consultants in rehabilitation programs or in the structures of counseling on the internet in Greece. Individual objectives they constituted the presentation of scientific methods and used techniques by the therapeutic counselors but also the ways of intervention at the phase of “relapse” of individual. For this reason, was realized a qualitative study which was conducted through individual personal interviews with semi-structured questions. The study involved a total of 10 therapeutic consultants – employees in rehabilitation programs or in the structures of counseling on the internet. The results of research highlighted the difficulty of therapeutic consultants to define the addiction from the Internet, the variety of roles and techniques but also the tendency for non-use of meaning “relapse” in this sector. Finally, the results offer suggestions and ideas for future researches that will be useful for the prevention and treatment of the phenomenon and for the information of the family and responsible institutions
