description: We define the discrete-time quantum walk on complex networks and utilize it for community detection. We numerically show that the quantum walk with the Fourier coin is localized in a community to which the initial node belongs. Meanwhile, the quantum walk with the Grover coin tends to be localized around the initial node, not over a community. The probability of the classical random walk on the same network converges to the uniform distribution with a relaxation time generally a priori. We thus claim that the time average of the probability of the Fourier-coin quantum walk on complex networks reveals the community structure more explicitly than that of the Grover-coin quantum walk and a snapshot of the classical random walk. We first demonstrate our method of community detection for a prototypical three-community network, producing the correct grouping. We then apply our method to two real-world networks, namely Zachary's karate club and the US Airport network. We successfully reveals the community structure, the two communities of the instructor and the administrator in the former and major airline companies in the latter.

description: We present the properties of the inverse Evershed flow (IEF) based on the center-to-limb variation of the plasma speed and loop geometry of chromospheric superpenumbral fibrils in eleven sunspots that were located at a wide range of heliocentric angles from 12 to 79 deg. The observations were acquired at the Dunn Solar Telescope in the spectral lines of Halpha at 656nm, CaII IR at 854 nm and HeI at 1083 nm. All sunspots display opposite line-of-sight (LOS) velocities on the limb and center side with a distinct shock signature near the outer penumbral edge. We developed a simplified flexible sunspot model assuming axisymmetry and prescribing the radial flow speed profile at a known loop geometry to replicate the observed two-dimensional IEF patterns under different viewing angles. The simulated flow maps match the observations for chromospheric loops with 10-20 Mm length starting at 0.8-1.1 sunspot radii, an apex height of 2-3Mm and a true constant flow speed of 2-9km/s. We find on average a good agreement of the simulated velocities and the observations on elliptical annuli around the sunspot. Individual IEF channels show a significant range of variation in their properties and reach maximal LOS speeds of up to 12km/s. Upwards or downwards directed flows do not show a change of sign in the LOS velocities for heliocentric angles above 30 deg. Our results are consistent with the IEF being caused by a siphon flow mechanism driving a flow at a constant sonic speed along elevated loops with a flattened top in the chromosphere.

description: In a celebrated work by Hoeffding [J. Amer. Statist. Assoc. 58 (1963) 13-30], several inequalities for tail probabilities of sums M_n=X_1+... +X_n of bounded independent random variables X_j were proved. These inequalities had a considerable impact on the development of probability and statistics, and remained unimproved until 1995 when Talagrand [Inst. Hautes Etudes Sci. Publ. Math. 81 (1995a) 73-205] inserted certain missing factors in the bounds of two theorems. By similar factors, a third theorem was refined by Pinelis [Progress in Probability 43 (1998) 257-314] and refined (and extended) by me. In this article, I introduce a new type of inequality. Namely, I show that P{M_n\geq x}\leq cP{S_n\geq x}, where c is an absolute constant and S_n=ε_1+... +ε_n is a sum of independent identically distributed Bernoulli random variables (a random variable is called Bernoulli if it assumes at most two values). The inequality holds for those x\in R where the survival function x\mapsto P{S_n\geq x} has a jump down. For the remaining x the inequality still holds provided that the function between the adjacent jump points is interpolated linearly or \log-linearly. If it is necessary, to estimate P{S_n\geq x} special bounds can be used for binomial probabilities. The results extend to martingales with bounded differences. It is apparent that Theorem 1.1 of this article is the most important.

description: We present globally supersymmetric models of gauged scale covariance in ten, six, and four-dimensions. This is an application of a recent similar gauging in three-dimensions for a massive self-dual vector multiplet. In ten-dimensions, we couple a single vector multiplet to another vector multiplet, where the latter gauges the scale covariance of the former. Due to scale covariance, the system does not have a lagrangian formulation, but has only a set of field equations, like Type IIB supergravity in ten-dimensions. As by-products, we construct similar models in six-dimensions with N=(2,0) supersymmetry, and four-dimensions with N=1 supersymmetry. We finally get a similar model with N=4 supersymmetry in four-dimensions with consistent interactions that have never been known before. We expect a series of descendant theories in dimensions lower than ten by dimensional reductions. This result also indicates that similar mechanisms will work for other vector and scalar multiplets in space-time lower than ten-dimensions.

Jene, teilweise humanoiden, Geschöpfe offenbaren eine greifbare Verdichtung von Technik und Natur.

Ausgehend von einem solaren Städtebau an den lagrang´schen Punkten haben sich acht Häfen in geostationären - und acht in terrestrischen Zonen entwickelt. Vorliegend wird ein terrestrischer Bündler, ein Hafen auf offener See, welcher als Schnittstelle zwischen Erde und All fungiert, architektonisch ausformuliert. dieser Verteiler von Energieformen ist tief im blauen Planeten verankert. Hyperloop-Stränge, Fluggeräte und Schiffe fungieren im terrestrischen Hafen als Zubringer, während Wal- und Pinguin ähnliche Gebilde die Reise in geostationäre Zonen in variablen Geschwindigkeiten ermöglichen.
description: The design aligns itself within a virtual time matrix, taking place in the year 2153. Emo(tion)spheres, perception of time in qualities and empathy as currency are parts of everyday life for any being. These, sometimes humanoid, beings palpably represent a consolidation of technology with nature. The beings live in symbiosis with other biotic or artificial life forms, together spreading across the earth’s solar system. Solar-urban planning across the lagrange points has produced eight geo-stationary and eight terrestrial ports. The design at hand explores the architectural elements making up one such focal point, a port located terra-side at open sea, acting as an interface linking earth and space. This channel of energy forms is anchored deeply within the surface of the blue planet. Hyperloop-strings, aircraft and ships convey earth-side travellers, while whale- and penguin like structures facilitate supersonic voyages into geostationary zones.

description: This is a translation (by DeepL and Margo Bargheer) of the quality standards for open access books that members of the working group of German-speaking university presses jointly compiled and published in 2018 (see Qualitätsstandards für Open Access Monographien und Sammelbände). They were the result of an intense discussion process. According to the members of the working group, the following standards determine the quality of open access books. While we are aware that for various reasons not all publications being available in open access nor all those services publishing open access can meet these standards, we formulate the standards open access for books should be judged against. Since the year 2018 several funding programs for open access books have emerged that need to rely on established and reasonable standards to judge funding eligibility. So by now there are more aspects to open access books than covered by our 2018 paper. However we are convinced that the following ones remain the key aspects for high-quality publishing of open access books.

description: Approximations to sums of stationary and ergodic sequences by martingales are investigated. Necessary and sufficient conditions for such sums to be asymptotically normal conditionally given the past up to time 0 are obtained. It is first shown that a martingale approximation is necessary for such normality and then that the sums are asymptotically normal if and only if the approximating martingales satisfy a Lindeberg-Feller condition. Using the explicit construction of the approximating martingales, a central limit theorem is derived for the sample means of linear processes. The conditions are not sufficient for the functional version of the central limit theorem. This is shown by an example, and a slightly stronger sufficient condition is given.

description: En los países en desarrollo, la distribución desigual de la calidad de los docentes es un problema que subyace a la distribución desigual de los logros educativos. Sin embargo, poco se sabe sobre cómo el mercado laboral genera este tipo de distribución. Para contribuir a este tipo de conocimiento, este estudio investiga si existe un mercado nacional de docentes en el Perú o, más bien, mercados regionales de menor alcance. En base a modelos multinomiales de elección discreta —estimados con datos de encuestas en las regiones de Loreto y Lambayeque—, se identifican las variables asociadas a la ubicación del primer empleo de los docentes, que incluyen factores geográficos y características de los maestros y del marco institucional. Los resultados revelan que los mercados de docentes son de alcance regional: haber nacido en una provincia determinada aumenta significativamente la probabilidad de conseguir el primer empleo como docente en esa misma provincia. También se encuentra evidencia de que la movilidad geográfica de los docentes es bastante limitada. Estos hallazgos sugieren que las políticas para fortalecer los sistemas de formación docente y reducir las inequidades deben centrarse en el nivel regional.

description: The orbital angular momentum conservation of light reveals different diffraction patterns univocally dependent on the topological charge of the incident light beam when passing through a triangular aperture. It is demonstrated that these patterns, which are accessed by observing the far field measurement of the diffracted light, can also be obtained using few photon sources. In order to explain the observed patterns, we introduce an analogy of this optical phenomenon with the study of diffraction for the characterization of the crystal structure of solids. We demonstrate that the finite pattern can be associated to the reciprocal lattice obtained from the direct lattice generated by the primitive vectors composing any two of the sides of the equilateral triangular slit responsible for the diffraction. Using the relation that exists between the direct and reciprocal lattices, we provide a conclusive explanation of why the diffraction pattern of the main maxima is finite. This can shed a new light on the investigation of crystallographic systems.

description: Spatial Kerr solitons, typically associated with the standard paraxial nonlinear Schroedinger equation, are shown to exist to all nonparaxial orders, as exact solutions of Maxwell's equations in the presence of vectorial Kerr effect. More precisely, we prove the existence of azimuthally polarized, spatial, dark soliton solutions of Maxwell's equations, while exact linearly polarized (2+1)-D solitons do not exist. Our ab initio approach predicts the existence of dark solitons up to an upper value of the maximum field amplitude, corresponding to a minimum soliton width of about one fourth of the wavelength.

description: Die Idee einer Musikschule und eines Veranstaltungszentrums kam von der Notwendigkeit und dem Wunsch, alle Leute und begabte Kinder aus der Stadt und aus anderen Bereichen in einem einzigen Ort zu sammeln, um zu studieren und zu kommunizieren. Das Projekt heißt „Musikgarten“ und das Raumprogramm wird auf 2 Baukörper aufgeteilt. Der „Musikgarten“ ist keine klassische Schule, sondern eine Institution mit außerschulischen Aktivitäten wie Theater, Tanz, neue Medien und ein großer Versammlungsort. Der ausgewählte Ort ist zwischen einer Eisenbahn Überführung und einer kleinen Wohnsiedlung. Die fehlende Identität des Wohnungsbezirks und die Nähe der kleinen gesellschaftlichen Orte rund um den Ort machten den „Musikgarten“ zu einem Identitätselement der Stadt. Wichtig für das Projekt ist eine Offenheit nach außen (Vorplatz mit Sommerbühne) und eine Synergie zwischen Natur und Architektur. Ziel meiner Diplomarbeit ist es, aufbauend auf einem Raumprogramm laut Wettbewerb Angaben für 50 Schüler, zeitgemäße Unterrichtsräume für musikalisches Schaffen zu kreieren. Zusätzlich wird ein Konzertsaal für rund 600 Personen entstehen, welcher eigenständig benutzt und an verschiedene raumakustische Anforderungen angepasst werden kann.
description: The idea of a Musical Garden and an event centre developed because of the need and wish to bring all people and talented children together in one place, for them to study and communicate. The project is called „Musical garden“ and the space program is divided into two structures. The „Musical garden“ is not a usual school, it is an institution with extracurricular activities like theatre, dance, new media and a large gathering spot. The chosen place is situated between a railroad overpass and a small housing development. The missing identity of this apartment district and the closeness of the small social places around made the „Musical garden“ an identity element of the city. An important part of this project is its openness outward (space with summer stage) and a synergy between nature and architecture. The goal of my thesis is, based on a room program according to the contest information for 50 students, creating contemporary teaching rooms for musical creation. Additionally there will be a concert hall for approximately 600 people, which can be used independently and be adjusted depending on the room acoustic conditions.

description: La literatura ha mostrado la importancia de las características individuales en el acceso de los estudiantes a la educación superior. En este documento se utiliza un diseño longitudinal con tres rondas de recolección de datos a fin de examinar los efectos de las características individuales y escolares en la decisión de los estudiantes de postular a educación superior. La muestra incluye estudiantes de instituciones educativas públicas y privadas en Lima, Perú, que se graduaron de la secundaria en el año 2010. Los resultados sugieren que un conjunto de factores individuales y escolares predicen la postulación a educación superior de los jóvenes al año de graduarse de educación secundaria. Aquellos estudiantes que tienen por lo menos un padre con educación superior, tienen casi dos veces más probabilidades de postular a estudios superiores que sus pares cuyos padres poseen solo educación primaria; mientras que los estudiantes de instituciones educativas donde se tomaron más acciones para favorecer su postulación tienen 1,25 veces más probabilidades de postular a educación superior que sus pares de instituciones donde ofrecen menos apoyo institucional, incluso tras controlar por variables a nivel individual y de la escuela. Con respecto al proceso de postulación a educación superior, los alumnos refieren que durante el proceso no solo enfrentan barreras económicas sino también psicológicas, relacionadas principalmente con la falta de información sobre qué y dónde estudiar y un apoyo adecuado por parte de la familia y la escuela. En base a los resultados del estudio se realizan recomendaciones de políticas y programas educativos que favorezcan el acceso de los jóvenes a educación superior.

description: Mejorar la efectividad de la política fiscal respecto a la redistribución y la reducción de la pobreza es clave para el desarrollo equitativo del Perú. Estudios recientes sugieren que las transferencias públicas y las donaciones son responsables de solo un décimo de la disminución de la pobreza alcanzada en la última década. A través del análisis de la incidencia de impuestos y transferencias en base a datos de encuestas de hogares, este estudio estima los efectos de la política fiscal sobre la pobreza y la desigualdad en nuestro país. Los hallazgos muestran que el alcance de la reducción de la desigualdad generada por la política fiscal del Perú es limitado. Ello se asocia a un gasto social bajo más que a un gasto social ineficiente. La mayoría de los componentes del gasto social son progresivos y el gasto social en general también lo es: las transferencias monetarias directas están bien focalizadas y son efectivas sobre todo en la reducción de la pobreza extrema en áreas rurales. Al mismo tiempo, las transferencias en especie de salud y educación son efectivas en la reducción de la desigualdad. Finalmente, se encuentra que los impuestos directos mitigan ligeramente la desigualdad mientras que los impuestos indirectos son neutrales cuando se incorpora la informalidad a los cálculos. Una implicancia de política es que las transferencias focalizadas son la forma más efectiva de reducir la pobreza a corto plazo. En contraste, la vinculación de beneficios sociales con el empleo formal tiende a excluir a los pobres.

description: For quite some time long-only index funds have been suspected of being responsible for price increases in agricultural futures markets. This suspicion has prompted demands to drastically limit long-only index funds' scope of activity. Such demands and their underlying diagnoses, however, contradict the current state of scientific knowledge. To date, the empirically oriented literature has not provided conclusive evidence that long-only index funds with their futures transactions significantly have increased the level or volatility of agricultural commodity prices. Indeed, recent theoretical works suggest that long-only index funds, pursuant to their investment strategy, rather stabilize agricultural commodity prices and fulfill an important collateralization and competition function in agricultural futures markets. The commitment to these funds reduces risk premiums and thus enables food producers to hedge against price fluctuations at lower costs. Mitigated risk premiums motivate farmers to put larger parts of their harvests into storage, which counteracts seasonal price fluctuations. To safeguard sustainable global food supply, long-only index funds should not be subjected to stricter market entry regulations.
Asking and answering questions during a programming change task
Creators: name: Sillito, Jonathan
Publisher: name: University of British Columbia
Year: 2011

description: Despite significant existing empirical work, little is known about the specific kinds of questions programmers ask when evolving a code base. Understanding precisely what information a programmer needs about the code base as they work is key to determining how to better support the activity of programming. The goal of this research is to provide an empirical foundation for tool design based on an exploration of what programmers need to understand about a code base and of how they use tools to discover that information. To this end, we undertook two qualitative studies of programmers performing change tasks to medium to large sized programs. One study involved newcomers working on assigned change tasks to a medium-sized code base. The other study involved industrial programmers working on their own change tasks to code with which they had experience. The focus of our analysis has been on what information a programmer needs to know about a code base while performing a change task and also on how they go about discovering that information. Based on a systematic analysis of the data from these user studies as well as an analysis of the support that current programming tools provide for these activities, this research makes four key contributions: (1) a catalog of 44 types of questions programmers ask, (2) a categorization of those questions into four categories based on the kind and scope of information needed to answer a question, (3) a description of important context for the process of answering questions, and (4) a description of support that is missing from current programming tools.

Das prominente große Grundstück befindet sich in der Cuvrystraße 50-51, am Ufer der Spree, im angesagten und trendigen Bezirk Kreuzberg. Der Ortsteil ist für seine multikulturellen BewohnerInnen und ein lebendiges alternatives Kulturleben bekannt. Von 2012 bis 2014 befand sich auf dem noch unbebauten Grundstück eine nicht offiziell zugelassene Siedlung, die sogenannte „Cuvrybrache“ oder „Cuvryfavela“. Die Eigentümer des Grundstückes hatten bereits mehrere Entwürfe für ein Einkaufszentrum, Büros und Luxuswohnungen erstellen lassen. Proteste und Demonstrationen gegen diese Pläne waren jedoch die Folge. Die Bewohner des Viertels, die bekannt für ihren starken sozialen Zusammenhalt sind, forderten ein Konzept für gemeinschaftliches und leistbares Wohnen. In dem Projekt habe ich das starke Gemeinschaftsgefühl des Viertels berücksichtigt und mit unterschiedlichen kollektiven Wohnformen versucht, verschiedene Ansprüche zu erfüllen. Der Gebäudekomplex soll nicht nur dessen Bewohnern dienen, sondern den Bewohnern der ganzen Umgebung eine Vielzahl an gemeinschaftlich nutzbaren Räumen und Plätzen bieten.
description: In this thesis I present my design process and plan for an apartment complex in Berlin. The focus of this project is on communal living or cohousing. This prominent plot is located at Cuvry Street 50-51, on the riverside of the Spree, in the trendy Kreuzberg district. This district is well-known for its multicultural character and alternative cultural life. In the period 2012-2014 people settled illegally on this undeveloped piece of land. The so-called „Cuvryfavela“ was an act of protest against the increasing commercialization of housing and continued elimination of spaces for public use in the city. The owners of the plot had already submitted several plans for a shopping mall, office building and complex of penthouses. These plans have led to massive demonstrations and protests, mainly initiated by inhabitants of the district. Well-known for their strong social fabric and community spirit, they demanded the realization of a residential building that provides space for social contacts and housing at affordable rents. The concept considers the strong community spirit of the inhabitants of this area and offers different forms of cohousing or communal living. In addition to individual apartments, rooms and facilities are offered that are shared by the tenants. Intentionally some places and rooms are also open for people from outside.

description: We study the relative entropy density for generalized Gibbs measures. We first show its existence and obtain a familiar expression in terms of entropy and relative energy for a class of ``almost Gibbsian measures'' (almost sure continuity of conditional probabilities). For quasilocal measures, we obtain a full variational principle. For the joint measures of the random field Ising model, we show that the weak Gibbs property holds, with an almost surely rapidly decaying translation-invariant potential. For these measures we show that the variational principle fails as soon as the measures lose the almost Gibbs property. These examples suggest that the class of weakly Gibbsian measures is too broad from the perspective of a reasonable thermodynamic formalism.

description: Using the CANDELS photometric catalogs for the HST/ACS and WFC3, we identified massive evolved galaxies at $3 < z < 4.5$, employing three different selection methods. We find the comoving number density of these objects to be $\sim 2 \times 10^{-5}$ and $8 \times 10^{-6}Mpc^{-3}$ after correction for completeness for two redshift bins centered at $z=3.4, 4.7$. We quantify a measure of how much confidence we should have for each candidate galaxy from different selections and what are the conservative error estimates propagated into our selection. Then we compare the evolution of the corresponding number densities and their stellar mass density with numerical simulations, semi-analytical models, and previous observational estimates, which shows slight tension at higher redshifts as the models tend to underestimate the number and mass densities. By estimating the average halo masses of the candidates ($M_h \approx 4.2, 1.9, 1.3 \times 10^{12} M_\odot$ for redshift bins centered at $z=3.4, 4.1, 4.7$), we find them to be consistent with halos that were efficient in turning baryons to stars and were relatively immune to the feedback effects and on the verge of transition into hot-mode accretion. This can suggest the relative cosmological starvation of the cold gas followed by an overconsumption phase in which the galaxy consumes the available cold gas rapidly as one of the possible drivers for the quenching of the massive evolved population at high redshift.

description: Viele ländliche Räume in Ostdeutschland sind insbesondere seit der Wiedervereinigung von rapid gesunkenen und anhaltend geringen Geburtenzahlen und seit über 50 Jahren von selektiver Abwanderung betroffen, wobei die Siebungsfaktoren Alter, Geschlecht und Qualifikation in der Regel eng miteinander korrespondieren. Dies führt vielerorts nicht nur zu einer raschen Schrumpfung, Überalterung und "Übermännerung" im demographisch aktiven Alter der Bevölkerung in der ländlichen Gesellschaft, sondern auch zum Verlust der kulturellen und intellektuellen Ressourcen. Im gleichen Maße stagniert bzw. sinkt das wirtschaftliche Potenzial, so dass auf Dorfebene die Landwirtschaft oft der einzig verbliebene Wirtschaftsfaktor ist. Diese sich stetig entleerenden peripher-ländlichen Räume stellen quasi die "ländlichsten Räume" dar. In einem vom Wissenschaftsministerium Sachsen-Anhalts unterstützten Projekt wurde am IAMO untersucht, inwieweit die Landwirtschaft vom demographischen Wandel betroffen ist und ob sie einen Beitrag zur öffentlichen Daseinsvorsorge leisten kann. Die Ergebnisse zeigen, dass die Betriebe, insbesondere Genossenschaften und GmbHs, immer stärkere Probleme haben, geeignete Fachkräfte und Lehrlinge zu finden. Zugleich wird deutlich, dass ein Großteil der landwirtschaftlichen Betriebsleiter - selbstständige Landwirte sowie Leiter von juristischen Personen - bereit ist, Aufgaben der öffentlichen Daseinsvorsorge zu übernehmen.

description: Zur Umsetzung der aktuellen EU-Agrarreform hat die deutsche Agrarministerkonferenz beschlossen, dass zukünftig kleinere Betriebe und Hofnachfolger durch besondere Zulagen begünstigt werden soll. Infolge der regional sehr heterogenen Agrarstruktur ergeben sich hieraus erhebliche Umverteilungen von Ost- nach Süddeutschland. Simulationsanalysen für ausgewählte Regionen in Ost- und Süddeutschland zeigen jedoch, dass die pauschale Begünstigung von kleineren Betrieben und Hofnachfolgern zwar die Überlebenswahrscheinlichkeit unrentabler Betriebe durch Anreize zur Fortführung leicht erhöht. Verbesserte Entwicklungsmöglichkeiten entstehen ihnen jedoch kaum. Zum einen verfügen selbst kleinere Neben- und Haupterwerbsbetriebe trotz ihrer geringen Rentabilität ohnehin zumeist über eine hohe Eigenkapitalausstattung. Zum anderen konkurrieren sie insbesondere in Süddeutschland mit anderen kleineren und mittleren Betrieben, die sich in einer ähnlichen Situation befinden, so dass die Zusatzzahlungen in Form höherer Pachtpreise und einer Strukturkonservierung verpuffen. Umgekehrt bedeuten die Zahlungseinbußen größerer Betriebe für diese auch kaum schwerwiegende langfristige Nachteile; denn sie konkurrieren vor allem mit anderen größeren Betrieben, die ebenfalls von Zahlungseinbußen betroffen sind. Politisch bedenklich sind die Beschlüsse dennoch. Vor allem erschweren sie zukünftige und längst überfällige Reformen.

description: The efficacy of the entry price policy in the European fresh fruits and vegetables sector is not well understood. We investigate econometrically the efficacy of the import policy. The analysis estimates a threshold vector autoregressive model using data on imports the main competing country on the European Union domestic markets. Our results allow concluding on the insulating effects induced by the entry price system. We argue that the quota restrictions are likely to provide larger contribution to the domestic market stabilization. Policy implications are provided.
Time and depression: conceptualization and expression

description: Expressing abstract concepts using figurative language, such as metaphor or metonymy (either verbally or non-verbally) is very common. The present thesis dealt with the abstract concepts of time and depression. More specifically, the way depressive patients experience time, as well as how this experience changes for non-depressive people were examined. In order to do so, two types of figurative language, namely metaphor and hyperbole, were detected and analyzed, while Conceptual Metaphor Theory (CMT) by Lakoff and Johnson (1980) and the theory on hyperbole by Peña and Ruiz de Mendoza (2017) were used for the analysis accordingly.
description: Η έκφραση αφηρημένων εννοιών χρησιμοποιώντας μη κυριολεκτική γλώσσα, όπως η μεταφορά ή η μετωνυμία (είτε λεκτικά είτε μη λεκτικά), είναι πολύ συνηθισμένο φαινόμενο. Η παρούσα μεταπτυχιακή διατριβή ασχολήθηκε με τις αφηρημένες έννοιες του χρόνου και της κατάθλιψης. Πιο συγκεκριμένα, εξετάστηκαν ο τρόπος που οι καταθλιπτικοί ασθενείς βιώνουν τον χρόνο καθώς επίσης και πώς αυτή η εμπειρία είναι διαφορετική για τους μη-καταθλιπτικούς ανθρώπους. Προκειμένου να πραγματοποιηθεί αυτό, δύο είδη μη-κυριολεκτικής χρήσης της γλώσσας, δηλαδή η μεταφορά και η υπερβολή, ανιχνεύθηκαν και αναλύθηκαν, ενώ η Θεωρία της Εννοιακής Μεταφοράς των Lakoff και Johnson (1980) και η θεωρία της υπερβολής των Peña και Ruiz de Mendoza (2017), χρησιμοποιήθηκαν αντιστοίχως για την ανάλυση.

Abstract: Considering that malnutrition is one of the most important problems to be solved by multilateral development agencies, the main aims of this article are: (a) to present an overview of the recent statistics about the levels of starvation around the world; (b) to detail the misunderstanding of Economy and Development Sociology based on the demographic pressure and the maintenance of tradition; (c) to analyze the consequences of the intervention policies, and (d) to present the theories that pro-pose the importance of inner structural reasons to explain the situation

description: Στην παρούσα διπλωματική εργασία μελετήθηκε ο ρόλος των Μέσων Κοινωνικής Δικτύωσης στην διάδραση των ελληνικών Μουσείων με το κοινό τους. Πιο συγκεκριμένα, αναλύθηκε η εξοικείωση των επισκεπτών με την τεχνολογία και πως αυτή επιδρά στις αντιδράσεις τους σχετικά με τα Μέσα Κοινωνικής Δικτύωσης, την διαμόρφωση της εμπειρίας τους, αλλά και την ικανοποίηση τους από το περιεχόμενο των Μέσων Κοινωνικής Δικτύωσης των ελληνικών Μουσείων. Έπειτα, εξετάστηκε η αξιοποίηση των Μέσων Κοινωνικής Δικτύωσης από τα ελληνικά Μουσεία και πως αυτή επηρεάζει την συνολική εμπειρία του επισκέπτη κατά την διάρκεια, αλλά και μετά το πέρας της επίσκεψής του. Ακόμη ιδιαίτερη σημασία δόθηκε και στην συνολική ψηφιακή παρουσία των ελληνικών Μουσείων και τον ρόλο της στη διαμόρφωση της εμπειρίας του επισκέπτη. Όσον αφορά στην μεθοδολογία, πραγματοποιήθηκε μια ποσοτική έρευνα, η οποία διενεργήθηκε τόσο διαδικτυακά, όσο και με δια ζώσης διαμοιρασμό ερωτηματολογίων. Τα συμπεράσματα, στα οποία καταλήξαμε στηρίχθηκαν σε 356 έγκυρα ερωτηματολόγια, από ανθρώπους που διαθέτουν λογαριασμό σε τουλάχιστον ένα Μέσο Κοινωνικής Δικτύωσης. Για την ανάλυση των δεδομένων χρησιμοποιήθηκε το υπολογιστικό πρόγραμμα IBM SPSS. Τα αποτελέσματα, τα οποία προέκυψαν επιβεβαίωσαν και τις έξι ερευνητικές υποθέσεις που τέθηκαν. Αναδεικνύοντας την σημασία της εξοικείωσης με την τεχνολογία, σε σχέση με όλες τις μεταβλητές που εξετάστηκαν. Εξίσου σημαντική φάνηκε πως είναι και η αξιοποίηση των ΜΚΔ, αλλά και η συνολική ψηφιακή παρουσία των Μουσείων στην διαμόρφωση της εμπειρίας των επισκεπτών.
description: This master's thesis investigates the multifaceted relationship between technology familiarity, social media utilization, and their combined influence on visitor behavior and satisfaction within the context of Greek museums. In an era characterized by rapid technological advancements, museums are increasingly seeking innovative ways to connect with their audiences. This research endeavors to shed light on if and how these cultural institutions can harness the potential of technology, specifically social media, to better interact their visitors and enhance overall satisfaction. The study employs a quantitative survey methodology. This study contributes to the growing body of knowledge surrounding the integration of technology and social media in the museum sector, specifically in the Greek context. The insights gained can inform museum professionals and policymakers on strategies to enhance visitor interaction and satisfaction, ultimately helping to preserve and promote Greece's rich cultural heritage in an increasingly digital age. Results showed that technology familiarity, as well Museums’ Social Media and digital present are in relation to all the variables examined.
