description: Starting from the question of the relationship between emotions and literature, this article will offer some suggestions to compare the methods and some tools for the interpretation of literary works drawn from psychoanalysis and neurocognitive sciences. To clarify the differences and to justify the irreducibility of these two prospects, we chose to propose a reading of Sophocles' Ajax. The textual analysis will be 'counterpointed' by some reflections elaborated in Nietzschean's conflictual aesthetics, in particular in his Götzen-Dämmerung.
Prendendo le mosse dalla questione del rapporto tra emozioni e letteratura, in questo articolo offriamo alcuni spunti per confrontare i metodi e alcuni strumenti per l'interpretazione delle opere letterarie elaborati dalla psicoanalisi e dalle scienze neurocognitive. Per chiarire le differenze e per giustificare l'inassimilabilità delle prospettive indagate, abbiamo scelto di proporre una lettura dell'Aiace di Sofocle, alla quale fanno da contrappunto le riflessioni dell'estetica conflittuale nicciana elaborate in particolare nel Crepuscolo degli Idoli.

description: A detailed study of electronic phase transitions in the ionic Hubbard model at half filling is presented. Within the dynamical mean field approximation a series of transitions from the band insulator via a metallic state to a Mott-Hubbard insulating phase is found at intermediate values of the one-body potential $Δ$ with increasing the Coulomb interaction $U$. We obtain a critical region in which the metallic phase disappears and a {\it novel} coexistence phase between the band and the Mott insulating state sets in. Our results are consistent with those obtained at low dimensions, thus they provide a concrete description for the charge degrees of freedom of the ionic Hubbard model.

description: The dependencies of the B$_{i}$O$_{i}$ defect concentration on doping, irradiation fluence and particle type in p-type silicon diodes have been investigated. We evidenced that large data scattering occurs for fluences above $10^{12}$ 1 MeV neutrons/cm$^2$, becoming significant larger for higher fluences. We show that the B$_{i}$O$_{i}$ defect is metastable, with two configurations A and B, of which only A is detected by Deep Level Transient Spectroscopy and Thermally Stimulated Currents techniques. The defect's electrical activity is influenced by the inherent variations in ambient and procedural experimental conditions, resulting not only in a large scattering of the results coming from the same type of measurement but making any correlation between different types of experiments difficult. It is evidenced that the variations in [B$_{i}$O$_{i}^\mathrm{A}$] are triggered by subjecting the samples to an excess of carriers, by either heating or an inherent short exposure to ambient light when manipulating the samples prior to experiments. It causes $\approx$7h variations in both, the [B$_{i}$O$_{i}^\mathrm{A}$] and in the effective space charge. The analyses of structural damage in a diode irradiated with 10$^{19}$ 1 MeV neutrons/cm$^2$ revealed that the Si structure remains crystalline and vacancies and interstitials organize in parallel tracks normal to the Si-SiO$_{2}$ interface.

description: Che cosa significa studiare i bestseller? L’articolo si propone di rispondere alla domanda fornendo un modello teorico basato sulla comparazione testuale, sul riconoscimento di elementi costanti del discorso e sull’individuazione di uno stile cognitivo comune. Nell’articolo vengono condotte due analisi: la prima su un campione di otto romanzi di successo che raccontano vicende di solitudine; la seconda su quattro romanzi di successo che narrano storie di coppie esemplari.

The paper proposes a theoretical model for bestseller research in the field of the textual analysis. It focuses on the comparision of semantic, syntactic and pragmatic constants, and the application of cognitive concepts. The paper examines two samples of novels telling about loneliness and couple stories respectively.

description: Food security and sustainability have always been a high priority for many countries. Urban farming has outclassed traditional farming in recent years as it can produce higher yields and healthier crops with fewer land and water resources. Aquaponics – growing fish and plants in a symbiotic closed-loop ecosystem – has many environmental and health benefits. To increase its commercial viability, aquaponics is integrated with various emerging technologies such as the Internet of things, automation, alternative resources, artificial intelligence, green technology, extended reality, and advanced materials. This chapter reviews technological advances and challenges in aquaponics systems. The advantages and disadvantages of such emerging and disruptive technologies are presented and discussed. Recommendations for future research and development are also proposed.

description: Focusing using conventional lenses relies on the collection and interference of propagating waves, but discounts the evanescent waves that decay rapidly from the source. Since these evanescent waves contain the finest details of the source, the image suffers a loss of resolution and is referred to as 'diffraction-limited'. Superlensing is the ability to create an image with fine features beyond the diffraction limit, and can be achieved with a 'Veselago-Pendry' lens made from a metamaterial. Such a Veselago-Pendry superlens for imaging in free space must be stringently designed to restore both propagating and evanescent waves, but meeting these design conditions (isotropic n = epsilon_r = mu_r = -1) has proven difficult and has made its realization elusive. We demonstrate free-space imaging with a resolution over three times better than the diffraction limit at microwave frequencies using a Veselago-Pendry metamaterial superlens based on the negative-refractive-index transmission-line (NRI-TL) approach, which affords precise control over its electromagnetic properties and is also less susceptible to losses than other approaches. A microwave superlens can be particularly useful for illumination and discrimination of closely spaced buried objects over practical distances by way of back-scattering, e.g. in tumour or landmine detection, or for targeted irradiation/hyperthermia.

description: Κατά την επεξεργασία των υγρών αστικών αποβλήτων, μαζί με την τελική απορροή, παράγονται και ορισμένα υλικά, σημαντικότερο από τα οποία, τόσο ως προς τον όγκο, όσο και ως προς τη δυσκολία διαχείρισης και διάθεσης, είναι η ιλύς. Η διάθεση της ιλύος μπορεί να προκαλέσει δυσμενείς επιπτώσεις, καθώς εμπεριέχει συστατικά επιβλαβή για το περιβάλλον. Προκειμένου η ιλύς των αστικών λυμάτων να διατεθεί σωστά, και να αποφευχθούν οι δυσμενείς περιβαλλοντικές επιπτώσεις, είναι απαραίτητη η βελτίωση της ποιότητάς της. Στη παρούσα μελέτη συλλέχθηκαν δείγματα πρωτοβάθμιας, δευτεροβάθμιας, χωνεμένης και αφυδατωμένης ιλύος από την εγκατάσταση επεξεργασίας αστικών λυμάτων της Θεσσαλονίκης και χαρακτηρίστηκαν ως προς τις φυσικοχημικές τους παραμέτρους. Επιπλέον η πρωτοβάθμια ιλύς υποβλήθηκε σε επεξεργασία με έναν κατιονικό πολυηλεκτρολύτη και ένα φυσικό ορυκτό τον ατταπουλγίτη με σκοπό την αποτίμηση της βελτίωσης των φυσικών και χημικών χαρακτηριστικών της. Όσον αφορά τα φυσικοχημικά χαρακτηριστικά της ιλύος σε όλα τα στάδια επεξεργασίας που αναλύθηκαν, οι τιμές τους βρίσκονται σε επίπεδα, αντίστοιχα με ιλύες από άλλες εγκαταστάσεις επεξεργασίας λυμάτων, όπως προέκυψε από τη βιβλιογραφική ανασκόπηση. Όσον αφορά την επεξεργασία της πρωτοβάθμιας ιλύος με τον πολυηλεκτρολύτη παρατηρήθηκε σημαντική βελτίωση των χαρακτηριστικών της, καθώς αυξήθηκε η ικανότητα πύκνωσης και αφυδάτωσής της, οι οποίες ενισχύθηκαν ακόμη περισσότερο κατά τη κοινή επεξεργασία της πρωτοβάθμιας ιλύος με πολυηλεκτρολύτη και ατταπουλγίτη. Προτεινόμενη δόση των δύο ουσιών στην παρούσα μελέτη ήταν τα 0,2g/L πολυηλεκτρολύτη και 80g/L ατταπουλγίτη
description: Sludge is the main and the most significant byproduct during wastewater treatment, in terms of volume, and difficulty in handling and disposal. Disposal of sewage sludge affects the environment as the sludge may contain harmful components. In order to eliminate the environmental risk, sludge quality characteristics should be improved.The objective of this study is to evaluate the physicochemical characteristics of primary, secondary, digested and dewatered sludge from Thessaloniki’s Urban Wastewater Treatment Plant. In addition primary sludge was treated with, a cationic polyelectrolyte and a clay mineral, attapulgite, in order to evaluate sludge quality improvement. In terms of sludge characterization, physicochemical values were compared with literature values, and they were in good agreement. In terms of primary sludge treatment, polyelectrolyte improved sludge physicochemical characteristics, which were further enhanced by the combined treatment with polyelectrolyte and attapulgite. In the present study recommended dose of polyelectrolyte and attapulgite were 0.2 g/L polyelectrolyte and 80 g/L attapulgite

description: We report on the growth and functional characterization of epitaxial thin films of the multiferroic YMnO3. We show that using Pt as a seed layer on SrTiO3(111) substrates, epitaxial YMnO3 films (0001) textured are obtained. An atomic force microscope has been used to polarize electric domains revealing the ferroelectric nature of the film. When a Permalloy layer is grown on top of the YMnO3(0001) film, clear indications of exchange bias and enhanced coercivity are observed at low temperature. The observation of coexisting antiferromagnetism and electrical polarization suggests that the biferroic character of YMnO3 can be exploited in novel devices.

Exploiting anticommutation in Hamiltonian simulation

subject: FOS: Physical sciences

description: Quantum computing can efficiently simulate Hamiltonian dynamics of many-body quantum physics, a task that is generally intractable with classical computers. The hardness lies at the ubiquitous anti-commutative relations of quantum operators, in corresponding with the notorious negative sign problem in classical simulation. Intuitively, Hamiltonians with more commutative terms are also easier to simulate on a quantum computer, and anti-commutative relations generally cause more errors, such as in the product formula method. Here, we theoretically explore the role of anti-commutative relation in Hamiltonian simulation. We find that, contrary to our intuition, anti-commutative relations could also reduce the hardness of Hamiltonian simulation. Specifically, Hamiltonians with mutually anti-commutative terms are easy to simulate, as what happens with ones consisting of mutually commutative terms. Such a property is further utilized to reduce the algorithmic error or the gate complexity in the truncated Taylor series quantum algorithm for general problems. Moreover, we propose two modified linear combinations of unitaries methods tailored for Hamiltonians with different degrees of anti-commutation. We numerically verify that the proposed methods exploiting anti-commutative relations could significantly improve the simulation accuracy of electronic Hamiltonians. Our work sheds light on the roles of commutative and anti-commutative relations in simulating quantum systems.
H.D.’s Trilogy: The Multiplicity of Being

Publisher: name: Università degli Studi di Milano

description: This essay is an epistemological interrogation and should be read as one possible approach among others to H.D.’s poetic experiment in Trilogy. It argues that the empiricist tradition provides us with a series of concepts that may help us make sense of the poem, or, rather, understand a little better how the poem makes sense. In this respect, H.D.’s numerous polytheistic mythological allusions can be problematized as being at the service of a philosophy of the human subject, not considered as a fixed, alienated entity, but as a constantly evolving multiplicity whose main activity is to construct new relations or syntheses, thereby endlessly constructing itself in the process.

description: The conformal extensions of three kinds of special relativity with ISO(1,3)/SO(1,4)/SO(2,3) invariance on Mink/dS/AdS space, respectively, are realized on an SO(2,4)/Z_2 invariant projective null cone [N] as the (projective) boundary of the 5-d AdS-space. The relations among the conformal Mink/dS/AdS spaces, the motions of light signals and the conformal field theories on them can be given. Thus, there should be a triality for these conformal issues and the conjectured AdS/CFT correspondence.

An investication of the participation of boys in family management courses
Creators: name: Hall, Ellen Clare
Publisher: name: University of British Columbia
Year: 2008

description: This study examined boys' participation in Family Management. It looked at non-enrolled boys' perceptions of Family Management, enrolled boys' experiences in Family Management, and boys' beliefs about the relevance of Family Management to their present and future family lives. Data were collected from student interviews, teacher interviews, and classroom observations at two different sites. One site had a high participation rate for boys in Family Management while the other site had a low participation rate. The study found that boys' participation was less than girls' for a number of reasons. Boys' believed they would not use the information taught in Family Management in their future lives, as they could not envision themselves performing non-traditional work around the home. A second reason for boys' low participation was that they viewed the concepts taught in Home Economics as basic, boring, and common sense. Many boys felt they could pick up these concepts by watching their parents. Thirdly, boys selected courses they believed would help them secure a future job or career. The most powerful influence on boys' decisions to participate in Family Management at the high participation school was a recommendation from friends and school staff. The reputation of Family Management in the school also has influenced enrollment decisions. Boys' experiences in Family Management were varied and were influenced by the gender compositon of the class. Boys reported that some of the topics were oriented toward girls and not relevant to themselves. The presence of boys in Family Management had an effect on the classroom environment, student teacher interaction, and the way the teacher taught the class. Questions arising from this study included: (1) What are the expressed viewpoints of boys concerning the purposes of their education? (2) How can teachers reduce the stereotyping of boys and girls in Family Management courses and foster appreciations of the diversity of girls and boys? (3) Has the enrollment of boys within Family Management contributed to gender inequity for the girls?

description: This study compared the assessments of four observers in 16 slaughterhouses on the most valid and feasible indicators of consciousness in two stages. Immediately after stunning, the refined list of indicators consists in tonic-clonic seizure, breathing, spontaneous blinking and vocalisations. During bleeding, the refined list includes breathing, spontaneous blinking and vocalisations. Sometimes more than one indicator of consciousness is observed in the same rabbit. Caution with righting reflex should be taken ant it should only be considered indicator of consciousness when the rabbit is breathing and/or blinking. Some factors that contribute to effective stunning are: stun-to-stick interval of less than 5 s, using current above 200 mA and frequencies not above 50 Hz, and wetting the rabbits' heads. The more these key factors are present in a SH, the higher the odds of effective stunning in rabbits.

description: Studying the albedos of the planets and moons of the Solar System dates back at least a century. Of particular interest is the relationship between the albedo measured at superior conjunction, known as the ``geometric albedo", and the albedo considered over all orbital phase angles, known as the ``spherical albedo". Determining the relationship between the geometric and spherical albedos usually involves complex numerical calculations and closed-form solutions are restricted to simple reflection laws. Here we report the discovery of closed-form solutions for the geometric albedo and integral phase function, which apply to any law of reflection that only depends on the scattering angle. The shape of a reflected light phase curve, quantified by the integral phase function, and the secondary eclipse depth, quantified by the geometric albedo, may now be self-consistently inverted to retrieve globally averaged physical parameters. Fully Bayesian phase curve inversions for reflectance maps and simultaneous light curve detrending may now be performed due to the efficiency of computation. Demonstrating these innovations for the hot Jupiter Kepler-7b, we infer a geometric albedo of $0.25^{+0.01}_{-0.02}$, a phase integral of $1.77 \pm0.07$, a spherical albedo of $0.44^{+0.02}_{-0.03}$ and a scattering asymmetry factor of $0.07^{+0.12}_{-0.11}$.

description: Automatic annotation of documents with controlled vocabulary terms (descriptors) from a conceptual thesaurus is not only useful for document indexing and retrieval. The mapping of texts onto the same thesaurus furthermore allows to establish links between similar documents. This is also a substantial requirement of the Semantic Web. This paper presents an almost language-independent system that maps documents written in different languages onto the same multilingual conceptual thesaurus, EUROVOC. Conceptual thesauri differ from Natural Language Thesauri in that they consist of relatively small controlled lists of words or phrases with a rather abstract meaning. To automatically identify which thesaurus descriptors describe the contents of a document best, we developed a statistical, associative system that is trained on texts that have previously been indexed manually. In addition to describing the large number of empirically optimised parameters of the fully functional application, we present the performance of the software according to a human evaluation by professional indexers.

description: Young Massive Clusters (YMCs) and Super Star Clusters (SSCs) represent an extreme mode of star formation. Far-infrared imaging of the Magellanic Clouds has identified one potential embedded SSC, HSO BMHERICC J72.971176-69.391112 (HH in short), in the south-west outskirts of the Large Magellanic Cloud. We present Gemini Flamingos 2 and GSAOI near-infrared imaging of a 3'x3' region around HH in order to characterize the stellar content of the cluster. The stellar content is probed down to 1.5 Msun. We find substantial dust extinction across the cluster region, extending up to A_K of 3. Deeply embedded stars are associated with ALMA-detected molecular gas suggesting that star formation is ongoing. The high spatial resolution of the GSAOI data allows identification of the central massive object associated with the 13CO ALMA observations and to detect fainter low-mass stars around the H30alpha ALMA source. The morphology of the molecular gas and the nebulosity from adjacent star formation suggest they have interacted covering a region of several pc. The total stellar content in the cluster is estimated from the intermediate- and high-mass stellar content to be at least 10000 Msun, less than R136 with up to 100 000 Msun within 4.7 pc radius, but places it in the regime of a super star cluster. Based on the extinction determination of individual stars we estimate a molecular gas mass in the vicinity of HH of 6600 Msun, suggesting more star formation can be expected.

description: Στόχος της παρούσας εργασίας είναι η αποτίμηση υφιστάμενης πολυώροφης κατασκευής σύμφωνα με τα κριτήρια και τις διατάξεις που εισάγει ο Ευρωκώδικας 8 και ο Ελληνικός Κανονισμός Επεμβάσεων (ΚΑΝ.ΕΠΕ.). Το εννιώροφο κτίριο που μελετήθηκε κατασκευάστηκε την δεκαετία του 1950 στην πόλη της Θεσσαλονίκης. Το κτίριο είναι κατασκευασμένο εξ ολοκλήρου από οπλισμένο σκυρόδεμα. Ο φέρων οργανισμός του κτιρίου είναι μικτός, αποτελούμενος από πλάκες, δοκούς, υποστυλώματα και τοιχώματα. Εξετάζεται ο φορέας για ταυτόχρονη δράση του σεισμού στις οριζόντιες διευθύνσεις του κτιρίου. Η ελαστική μέθοδος ανάλυσης που εφαρμόζεται είναι αυτή της δυναμικής φασματικής. Η αποτίμηση ολοκληρώνεται με μη-γραμμική στατική ανάλυση (Pushover Analysis). Στη συνέχεια πραγματοποιείται ενίσχυση της κατασκευής. Οι αναλύσεις πραγματοποιήθηκαν με κατάλληλο χωρικό μοντέλο προσομοίωσης του εξεταζόμενου φορέα με το λογισμικό ανάλυσης ETABS.
description: The primary objective of the dissertation is to determine if the existing construction complies with the standards of Eurocode 8 and with the Greek Retrofit Code as well. The building of this case study has been made of reinforced concrete and constructed in the city of Τhessaloniki in the decade of 1950. Structure’s consisting of columns, beams, slabs and walls. The reinforced concrete frame has been tested in both horizontal axis in order to examine it’s seismic resistance behavior. The elastic method of analysis which has been used is the response spectrum analysis. The assessment has been completed with inelastic method of non-linear static analysis (Pushover Analysis). Furthermore the strengthening has been made by planning: jacketing on the existing columns to provide increased support. For the analysis a 3-D simulation model of structure has been created using the ETABS program.

Storicizzare le teorie psicocritiche

Publisher: name: Università degli Studi di Milano
Year: 2015

description: Le teorie psicoanalitiche della letteratura, dopo una fase di alterne fortune, sono oggi praticate da una cerchia di adepti sempre più ristretta. Le nuove koinè critico-teoriche tendono infatti a relegare la dottrina freudiana all’interno di un sapere letterario (e non interpretativo) o a sostituire ad essa strumenti ritenuti più efficaci nella descrizione della sfera del mentale in letteratura (neuroestetica e neuronarratologia). La proposta storiografica che qui si avanza non vuole prendere parte in questo dibattito pro o contro la psicocritica, ma vuole leggere le proposte di teoria psicoanalitica della letteratura alla luce di una riflessione sul concetto di ibridazione, concetto sul quale queste teorie hanno costruito il loro confronto con i paradigmi teorici di volta in volta egemoni.

description: Thermodynamic and transport characteristics of a clean two-dimensional interacting electron gas are shown to be sensitive to the weak perpendicular magnetic field even at temperatures much higher than the cyclotron energy, when the quantum oscillations are completely washed out. We demonstrate this sensitivity for two interaction-related characteristics: electron lifetime and the tunnel density of states. The origin of the sensitivity is traced to the field-induced smearing of the Kohn anomaly; this smearing is the result of curving of the semiclassical electron trajectories in magnetic field.

description: Gate capacitances of back-gated nanowire field-effect transistors (NW-FETs) are calculated by means of finite element methods and the results are compared with analytical results of the ``metallic cylinder on an infinite metal plate model''. Completely embedded and non-embedded NW-FETs are considered. It is shown that the use of the analytical expressions also for non-embedded NW-FETs gives carrier mobilities that are nearly two times too small. Furthermore, the electric field amplification of non-embedded NW-FETs and the influence of the cross-section shape of the nanowires are discussed.

description: In order to create user-centric and personalized privacy management tools, the underlying models must account for individual users' privacy expectations, preferences, and their ability to control their information sharing activities. Existing studies of users' privacy behavior modeling attempt to frame the problem from a request's perspective, which lack the crucial involvement of the information owner, resulting in limited or no control of policy management. Moreover, very few of them take into the consideration the aspect of correctness, explainability, usability, and acceptance of the methodologies for each user of the system. In this paper, we present a methodology to formally model, validate, and verify personalized privacy disclosure behavior based on the analysis of the user's situational decision-making process. We use a model checking tool named UPPAAL to represent users' self-reported privacy disclosure behavior by an extended form of finite state automata (FSA), and perform reachability analysis for the verification of privacy properties through computation tree logic (CTL) formulas. We also describe the practical use cases of the methodology depicting the potential of formal technique towards the design and development of user-centric behavioral modeling. This paper, through extensive amounts of experimental outcomes, contributes several insights to the area of formal methods and user-tailored privacy behavior modeling.

description: We present preliminary measurements of the cross section and the double longitudinal spin asymmetry in inclusive jet production in polarized p+p collisions at Sqrt(s) = 200 GeV. The measured cross section agrees well with NLO pQCD calculations over seven orders of magnitude. The observed spin asymmetries are consistent with theoretical evaluations based on deeply inelastic scattering data and tend to disfavor a large positive gluon polarization.

description: Most of the existing deep learning based end-to-end image/video coding (DLEC) architectures are designed for non-subsampled RGB color format. However, in order to achieve a superior coding performance, many state-of-the-art block-based compression standards such as High Efficiency Video Coding (HEVC/H.265) and Versatile Video Coding (VVC/H.266) are designed primarily for YUV 4:2:0 format, where U and V components are subsampled by considering the human visual system. This paper investigates various DLEC designs to support YUV 4:2:0 format by comparing their performance against the main profiles of HEVC and VVC standards under a common evaluation framework. Moreover, a new transform network architecture is proposed to improve the efficiency of coding YUV 4:2:0 data. The experimental results on YUV 4:2:0 datasets show that the proposed architecture significantly outperforms naive extensions of existing architectures designed for RGB format and achieves about 10% average BD-rate improvement over the intra-frame coding in HEVC.

description: Prendendo atto di quanto siano variegate opinioni e valutazioni sul metamorfico universo dei videogiochi, si cerca di circoscrivere una sua tipologia in rapporto ad un presunto canone romanzesco. A questo viene contrapposto un “controcanone” visivo che prospetta un happy end e si fa carico delle forme contemporanee dell’intermedialità.

description: A Killing bubble is a minimal surface that arises as the fixed surface of a spacelike Killing field. We compute the bubble contributions to the Smarr relations and the mass and tension first laws for spacetimes containing both black holes and Killing bubbles. The resulting relations display an interesting interchange symmetry between the properties of black hole horizons and those of KK bubbles. This interchange symmetry reflects the underlying relation between static bubbles and black holes under double analytic continuation of the time and Kaluza-Klein directions. The thermodynamics of bubbles involve a geometrical quantity that we call the bubble surface gravity, which we show has several properties in common with the black hole surface gravity.

description: The relativistic charged spinor matter field is quantized in the background of a straight cosmic string with nonvanishing transverse size. The most general boundary conditions ensuring the impossibility for matter to penetrate through the edge of the string core are considered. The role of discrete symmetries is elucidated, and analytic expressions for the temporal and spatial components of the induced vacuum current are derived in the case of either $P$ or $CT$ invariant boundary condition with two parameters varying arbitrarily from point to point of the edge. The requirement of physical plausibility for the global induced vacuum characteristics is shown to remove completely an arbitrariness in boundary conditions. We find out that a magnetic field is induced in the vacuum and that a sheath in the form of a tube of the magnetic flux lines encloses a cosmic string. The dependence of the induced vacuum magnetic field strength on the string flux and tension, as well as on the transverse size of the string and on the distance from the string, is unambiguously determined.

description: Η παρούσα έρευνα έχει σκοπό να ερευνήσει το κατά πόσο υπάρχουν περιστατικά χρήσης και διακίνησης ναρκωτικών ουσιών σε κέντρα υποδοχής και κέντρα φιλοξενίας προσφύγων. Αποσκοπεί στο να αναζητήσει τις αιτίες και τα αποτελέσματα της χρήσης και τον τρόπο διακίνησης των ουσιών. Η μέθοδος που υιοθετείται είναι η ποιοτική μέθοδος. Το εργαλείο που επιλέγεται είναι η ημι-δομημένη συνέντευξη. Οι συμμετέχοντες στην έρευνα είναι δεκαεπτά άτομα, οκτώ πρόσφυγες που διαμένουν σε camp της Ελλάδος και εννέα άτομα από το προσωπικό που στελεχώνει τις δομές αυτές. Τα αποτελέσματα αναλύονται με τη μέθοδο της ανάλυσης περιεχομένου. Αποτέλεσμα της έρευνας είναι η ύπαρξη περιστατικών χρήσης και διακίνησης ουσιών και κάποιες από τις αιτίες χρήσης είναι η μακροχρόνια παραμονή στα camp, η ανασφάλεια και η έλλειψη προστασίας. Επιπλέον μέσα από την έρευνα αναδεικνύεται ότι οι χρήστες ουσιών είναι κυρίως εξαρτημένοι και η διακίνηση γίνεται εντός και εκτός των κέντρων υποδοχής και φιλοξενίας προσφύγων. Σύμφωνα με τα αποτελέσματα, η χρήση ουσιών συχνά οδηγεί σε συμπλοκές μεταξύ των διαμένοντων στα camps και σε αυτοτραυματισμούς. Θέση της παρούσας έρευνας είναι ότι διαπιστώνεται χρήση ουσιών που συνδέεται με τις συνθήκες διαβίωσης. Ως φυσικό επακόλουθο, τα άτομα που κάνουν χρήση αναζητούν τις ουσίες είτε εντός είτε εκτός camp, με αποτέλεσμα να δημιουργούνται οι κατάλληλες συνθήκες για να αναπτυχθούν δίκτυα διακίνησης ουσιών
description: The purpose of this research is to investigate whether there are incidents of drug use and trafficking in reception centers and accommodation centers for refugees. It is intended to look for the causes and consequences of substance use and the way in which substances are distributed. A qualitative method based on semi-structured interviews is used. The participants in the research are seventeen, eight refugees who live in the camps and nine persons currently working at the camps. The results are analyzed using the content analysis method. The results of the survey show that there are incidents of substance use and trafficking caused by the long stay at the camps and the insecurity and lack of protection. It is found that drug users are mostly dependent on drugs and that trafficking takes place inside and outside reception and accommodation centers. According to the results, substance use often leads to fights between the residents of the camps and occasionally some people harm themselves. The thesis of this project is that there is substance use related to living conditions prevailing in the camps. As a consequence, people using drugs seek substances either inside or outside the camps, creating the right conditions for drug trafficking networks
