description: Currently, homosexual transmission has become one of the main routes of HIV-1 spread in China. Furthermore, about 80% Chinese men, who have sex with men (MSM), feel forced to enter eventually into heterosexual marriages due to the Chinese traditional marriage culture, which may cause HIV-1 infection in families. In this study, we identified HIV-1 transmission in a family and the direction of HIV-1 transmission from a MSM to his wife and infant, which indicated Chinese MSM may have become a potential bridge of HIV-1 transmission to their wives and children. Therefore, we need to develop more effective defence measures to prevent the spread of HIV-1 in MSM families in China.

description: Πολλές έρευνες, μέχρι σήμερα, διεθνώς, έχουν μελετήσει τη φύση του μνημονικού συστήματος καθώς και την περιορισμένη χωρητικότητα του όσον αφορά τις ομιλούμενες γλώσσες. Τα τελευταία χρόνια, όμως, πολλοί ερευνητές έχουν εστιάσει την προσοχή τους στην έρευνα των Νοηματικών Γλωσσών και στο κατά πόσο η χωρητικότητα της μνήμης είναι ίδια μέσω της αντίληψης των οπτικών ερεθισμάτων. Σκοπός της παρούσας έρευνας ήταν να διαπιστωθεί κατά πόσο η Ελληνική Νοηματική Γλώσσα, ως μητρική γλώσσα των Κωφών, συμβάλει στην ανάπτυξη της εργαζόμενης μνήμης. Συγκεκριμένα, μέσα από την επανάληψη προτάσεων και την αναδιήγηση ιστορίας διερευνήθηκε η μορφοσυντακτική πιστότητα και το είδος των λαθών που γίνονται κατά την επανάληψη στη Νοηματική γλώσσα. Στην έρευνα πήραν μέρος 8 ενήλικες με απώλεια ακοής και χωρίστηκαν σε ομάδες ανάλογα με την ηλικία εκμάθησης της Νοηματικής Γλώσσας. Τα αποτελέσματα έδειξαν ότι τα άτομα που απέκτησαν τη γλώσσα στη βρεφική ηλικία είχαν καλύτερη επίδοση στην επανάληψη από τους συμμετέχοντες που δεν απέκτησαν τη Νοηματική γλώσσα ως μητρική. Επίσης, αξιοσημείωτο είναι το γεγονός ότι οι ομάδες έρευνας 1 και 2 έκαναν περισσότερο μορφοσυντακτικά λάθη στην επανάληψη προτάσεων και πολλές παραλείψεις νοημάτων στην αναδιήγηση των ιστοριών
description: The system of our working memory and the limited capacity of retaining information have been investigated, worldwide, in spoken languages. However, in recent years, researchers have focused on understanding the natural of sign language and the capacity of signer’s memory in which only visual stimuli are recognized. The purpose of this research was to study the influence of learning the Sign Language in early age in the development of working memory. Retelling stories and the repetition of sentences were two tasks used for the assessment of working memory. The participants of this study were 8 adults who were participated in three small groups according to the age of acquiring Sign Language. The results of the study argued that participants who have acquired the Sign Language as maternal language outperform signers who have learned Sign Language up to 6 years old. Especially, groups 1 and 2 of research made more errors of morphosyntactic structure in the repetition of the sentences compared with the control group. Furthermore, in the task of retelling a story many sign omissions have been done by these groups. Αs a result the stories have not been repeated completely

description: We present the results of a detailed NLTE abundance study of nine beta Cephei stars, all of them being prime targets for theoretical modelling: gamma Peg, delta Cet, nu Eri, beta CMa, xi1 CMa, V836 Cen, V2052 Oph, beta Cep and DD (12) Lac. The following chemical elements are considered: He, C, N, O, Mg, Al, Si, S and Fe. Our abundance analysis is based on a large number of time-resolved, high-resolution optical spectra covering in most cases the entire oscillation cycle of the stars. Nitrogen is found to be enhanced by up to 0.6 dex in four stars, three of which have severe constraints on their equatorial rotational velocity, ΩR, from seismic or line-profile variation studies: beta Cep (ΩR~26 km/s), V2052 Oph (ΩR~56 km/s), delta Cet (ΩR < 28 km/s) and xi1 CMa (ΩR sin i < 10 km/s). The existence of core-processed material at the surface of such largely unevolved, slowly-rotating objects is not predicted by current evolutionary models including rotation. We draw attention to the fact that three stars in this subsample have a detected magnetic field and briefly discuss recent theoretical work pointing to the occurrence of diffusion effects in beta Cephei stars possibly capable of altering the nitrogen surface abundance. On the other hand, the abundances of all the other chemical elements considered are, within the errors, indistinguishable from the values found for OB dwarfs in the solar neighbourhood. Despite the mild nitrogen excess observed in some objects, we thus find no evidence for a significantly higher photospheric metal content in the studied beta Cephei stars compared to non-pulsating B-type stars of similar characteristics.

description: This paper introduces reviewability as a framework for improving the accountability of automated and algorithmic decision-making (ADM) involving machine learning. We draw on an understanding of ADM as a socio-technical process involving both human and technical elements, beginning before a decision is made and extending beyond the decision itself. While explanations and other model-centric mechanisms may assist some accountability concerns, they often provide insufficient information of these broader ADM processes for regulatory oversight and assessments of legal compliance. Reviewability involves breaking down the ADM process into technical and organisational elements to provide a systematic framework for determining the contextually appropriate record-keeping mechanisms to facilitate meaningful review - both of individual decisions and of the process as a whole. We argue that a reviewability framework, drawing on administrative law's approach to reviewing human decision-making, offers a practical way forward towards more a more holistic and legally-relevant form of accountability for ADM.

description: Let $\widetilde{\cal M}_{g,n}$, for $2g-2+n>0$, be the moduli stack of $n$-pointed, genus $g$, stable complex curves of compact type. Various characterizations and properties are obtained of both the algebraic and topological fundamental groups of the stack $\widetilde{\cal M}_{g,n}$. Let $Γ_{g,n}$, for $2g-2+n>0$, be the Teichmüller group associated with a compact Riemann surface of genus $g$ with $n$ points removed $S_{g,n}$, i.e. the group of homotopy classes of diffeomorphisms of $S_{g,n}$ which preserve the orientation of $S_{g,n}$ and a given order of its punctures. Let $K_{g,n}$ be the normal subgroup of $Γ_{g,n}$ generated by Dehn twists along separating circles on $S_{g,n}$. As a first application of the above theory, a characterization of $K_{g,n}$ is given for all $n\geq 0$ (for $n=0,1$, this was done by Johnson). Let then ${\cal T}_{g,n}$ be the Torelli group, i.e. the kernel of the natural representation $Γ_{g,n}\ra Sp_{2g}(Z)$. The abelianization of ${\cal T}_{g,n}$ is determined for all $g\geq 1$ and $n\geq 1$, thus completing classical results by Johnson and Mess.

description: The efficiency of Monte Carlo samplers is dictated not only by energetic effects, such as large barriers, but also by entropic effects that are due to the sheer volume that is sampled. The latter effects appear in the form of an entropic mismatch or divergence between the direct and reverse trial moves. We provide lower and upper bounds for the average acceptance probability in terms of the Renyi divergence of order 1/2. We show that the asymptotic finitude of the entropic divergence is the necessary and sufficient condition for non-vanishing acceptance probabilities in the limit of large dimensions. Furthermore, we demonstrate that the upper bound is reasonably tight by showing that the exponent is asymptotically exact for systems made up of a large number of independent and identically distributed subsystems. For the last statement, we provide an alternative proof that relies on the reformulation of the acceptance probability as a large deviation problem. The reformulation also leads to a class of low-variance estimators for strongly asymmetric distributions. We show that the entropy divergence causes a decay in the average displacements with the number of dimensions n that are simultaneously updated. For systems that have a well-defined thermodynamic limit, the decay is demonstrated to be n^{-1/2} for random-walk Monte Carlo and n^{-1/6} for Smart Monte Carlo (SMC). Numerical simulations of the LJ_38 cluster show that SMC is virtually as efficient as the Markov chain implementation of the Gibbs sampler, which is normally utilized for Lennard-Jones clusters. An application of the entropic inequalities to the parallel tempering method demonstrates that the number of replicas increases as the square root of the heat capacity of the system.

description: In a granular gas of rough particles the axis of rotation is shown to be correlated with the translational velocity of the particles. The average relative orientation of angular and linear velocities depends on the parameters which characterise the dissipative nature of the collision. We derive a simple theory for these correlations and validate it with numerical simulations for a wide range of coefficients of normal and tangential restitution. The limit of smooth spheres is shown to be singular: even an arbitrarily small roughness of the particles gives rise to orientational correlations.

University life and wellbeing : the association between financial factors and students' academic aspirations
Creators: name: Johnson, ML
Publisher: name: University of Tasmania
Year: 2024

description: University has an increasingly significant role in positively shaping students' life outcomes. Established theoretical models and past research indicate that income and financial stressors can impact students' academic aspirations, thereby reducing the likelihood of graduating from university. The current study built off the existing literature exploring the relationship between financial factors of income and financial stress on students' academic aspirations and expanded upon previous research to consider whether academic self-efficacy accounted for the disparities between students' academic aspirations, and if one's family social support attenuated low academic aspirations. The study analysed data collected from 64 university students studying at the University of Tasmania. Contrary to the hypotheses, there was no evidence for mediation or moderation. In summary, the current study suggests efforts to address students' financial disadvantages and improve the future life chances of students who may be underrepresented in post-secondary education.

description: Η παρούσα μεταπτυχιακή εργασία επιχείρησε να διερευνήσει πως η παρουσία χουμικών ενώσεων στο νερό μπορεί να επηρεάσει την αναγωγή του Cr(VI) και την προσρόφηση του Cr(ΙΙΙ). Για το σκοπό αυτό εξετάστηκε η αποτελεσματικότητα τριών διαφορετικών αναγωγικών προσροφητικών στην απομάκρυνση του Cr(VI) από το νερό παρουσία χουμικών ενώσεων σε διαφορετικές συγκεντρώσεις. Τα υλικά αυτά ήταν το κράμα χαλκού ψευδαργύρου με σύσταση 50-50 (CuZn50-50), ο μαγνητίτης (Fe3O4) και το υδροξυ-οξείδιο του κασσιτέρου [Sn6O4(OH)4]. Η μελέτη της απομάκρυνσης του Cr(VI) από το νερό παρουσία διαφορετικών συγκεντρώσεων χουμικών ενώσεων έδειξε ότι αυτή δεν επηρεάζει σημαντικά τη διαδικασία σε αντίθεση με την περίπτωση της αναγωγής του Cr(VI) με Fe(II), όπου ο σχηματισμός διαλυτών συμπλόκων Cr(III) με τις χουμικές ενώσεις επιδρά αρνητικά στην ιζηματοποίηση και τελικά στην απομάκρυνσή του ολικού χρωμίου. Αυτό πιθανό να οφείλεται στο διαφορετικό μηχανισμό απομάκρυνσης του Cr(VI) στην αναγωγική προσρόφηση. Στην περίπτωση αυτή το Cr(VI) αφού πλησιάσει την επιφάνεια του προσροφητικού ανάγεται σε Cr(III) με ταυτόχρονη οξείδωση του υλικού πάνω στην επιφάνεια του οποίου συγκρατείται με ισχυρού δεσμούς το Cr(III). Η παραγωγή των ισόθερμων προσρόφησης αποκάλυψε ότι η απομάκρυνση ευνοείται από τη μείωση του pH, όπως παρατηρείται και στην πλειοψηφία των προσροφητικών υλικών. Τα πειραματικά δεδομένα προσαρμόζονται και στα δύο μοντέλα προσρόφησης που εξετάστηκαν (Freundlich και Langmuir), ωστόσο το μοντέλο Langmuir περιγράφει καλύτερα τη διεργασία, καθώς η «αναγωγική προσρόφηση» είναι στην ουσία χημική αντίδραση
description: This master thesis has attempted to investigate how the presence of humic substances in water can affect the reductive adsorption of Cr(VI). For this purpose, the effectiveness of three different Cr(VI) reductive adsorbents was examined, in the presence of humic substances at different concentrations. These materials were zinc copper alloy (CuZn50-50), magnetite (Fe3O4) and tin oxy-hydroxide [Sn6O4(OH)4].The study of Cr(VI) removal in the presence of different concentrations of humic substances showed that it did not significantly affect the process. This is probably due to the mechanism of Cr(VI) removal followed in reductive adsorption. In this case, Cr(VI), after reaching the adsorbent’s surface, is reduced to Cr(III) by simultaneous oxidation of the material on the surface of which Cr(III) is strongly adsorbed. The production of adsorption isotherms revealed that Cr(VI) removal is favored at lower pH as observed for most adsorbents. The experimental data is adapted to both adsorption models examined (Freundlich and Langmuir), however the Langmuir model describes the process better, since the reduction-adsorption process is almost chemical reaction

description: This paper is devoted to the study of some aspects of the instability of two flavor color superconductive quark matter. We find that, beside color condensates, the Goldstone boson related to the breaking of $U(1)_A$ suffers of a velocity instability. We relate this wrong sign problem, which implies the existence of a Goldstone current in the ground state or of gluonic condensation, to the negative squared Meissner mass of the $8^{th}$ gluon in the g2SC phase. Moreover we investigate the Meissner masses of the gluons and the squared velocity of the Goldstone in the multiple plane wave LOFF states, arguing that in such phases both the chromo-magnetic instability and the velocity instability are most probably removed. We also do not expect Higgs instability in such multiple plane wave LOFF. The true vacuum of gapless two flavor superconductors is thus expected to be a multiple plane wave LOFF state.

description: We present a detailed Cu K-edge resonant inelastic X-ray scattering (RIXS) study of the Mott insulator La2CuO4 in the 1-7 eV energy transfer range. As initially found for the high-temperature superconductor HgBa2CuO4+d, the spectra exhibit a multiplet of weakly-dispersive electron-hole excitations, which are revealed by utilizing the subtle dependence of the cross section on the incident photon energy. The close similarity between the fine structures for in-plane and out-of-plane polarizations is indicative of the central role played by the 1s core hole in inducing charge excitations within the CuO2 planes. On the other hand, we observe a polarization dependence of the spectral weight, and careful analysis reveals two separate features near 2 eV that may be related to different charge-transfer processes. The polarization dependence indicates that the 4p electrons contribute significantly to the RIXS cross section. Third-order perturbation arguments and a shake-up of valence excitations are then applied to account for the final-energy resonance in the spectra. As an alternative scenario, we discuss fluorescence-like emission processes due to 1s -> 4p transitions into a narrow continuum 4p band.

description: Let ${\cal M}_{g,n}$, for $2g-2+n>0$, be the moduli stack of $n$-pointed, genus $g$, smooth curves. For a family $C\to S$ of such curves over a connected base and a geometric point $ξ$ on $S$, the associated monodromy representation is the induced homomorphism $π_1(S,ξ)\toπ_1({\cal M}_{g,n},[C_ξ])$ on algebraic fundamental groups. It is well known that, if $S$ is irreducible, reduced and locally of finite type over a field $k$ of characteristic zero, the fibre $C_ξ$ and the corresponding monodromy representation determine the relative isomorphism class of the family. In the first part of the paper, it is shown that suitable quotients of this representation suffice. These results are then applied to show that the monodromy representation associated to a family $C\to S$ of $n$-pointed, genus $g$, stable curves of compact type, i.e. the induced homomorphism $π_1(S,ξ)\toπ_1(\widetilde{\cal M}_{g,n},[C_ξ])$ (where, $\widetilde{\cal M}_{g,n}$ denotes the moduli stack of $n$-pointed, genus $g$, stable curves of compact type), characterizes trivial and isotrivial families. Let $U$ be an open subscheme of a normal, irreducible, locally noetherian scheme $S$ over a field $k$ of characteristic zero and let $C\ra U$ be a family of stable curves of compact type. In the second part of the paper, a monodromy criterion is given for extending $C\to U$ to a family of stable curves of compact type over $S$.

Ancestral Lines in Deterministic and Stochastic Mutation-Selection Models
Creators: name: Hummel, Sebastian
Publisher: name: Universität Bielefeld
Year: 2019
Subjects: subject: 510

description: Mutation-selection models are traditionally either deterministic or stochastic. Deterministic approaches assume that the size of the population is such that a law of large numbers applies so that random fluctuations may be neglected. The resulting models are (ordinary or partial) differential equations or (discrete-time) dynamical systems, which describe the evolution in the usual forward direction of time. In contrast, stochastic approaches take into account the fluctuations due to random reproduction; the resulting stochastic processes have a firm place in probability theory. Here, the corresponding ancestral processes, which describe the ancestry of a sample of individuals from a population at the present, play an eminent role in the analysis. Deterministic models of population genetics and their stochastic counterparts have largely led separate lives. It is the purpose of this thesis to bring these two areas of research closer together by extending the backward point of view, so far reserved for stochastic models of population genetics, to deterministic mutation-selection equations. The corresponding ancestral processes describe the history of a finite sample of individuals and remain random; although the type-frequency process of the entire population evolves deterministically. Tailored versions of the genealogical processes yield stochastic representations of the solutions of the deterministic equations. The analysis sheds new light on the deterministic dynamic and its long-term behaviour. Special emphasis is placed on the connection between bifurcation phenomena and ancestral structures. The genealogical approach allows the notion of a (random) ancestral type also in the deterministic setting and provides the framework to determine its distribution. We illustrate the underlying ideas by applying them to a special case of frequency-dependent selection. The ancestral processes for such models are largely unexplored territory. We first establish appropriate structures and then make them tractable by applying our aforementioned concepts. The tailored processes allow an explanation of the richer bifurcation structure by genealogical means and lead to expressions for the ancestral type distribution.

description: Si(001)-(2$\times$1) surface is one of the many two-dimensional systems of scientific and applied interest. It has two surface state bands (1) anti-bonding pi* band, which has acceptor states and (2) bonding pi band, which has donor states. Due to its asymmetric dimer reconstruction, transport through this surface can be considered in two distinct directions, i.e. along and perpendicular to the paired dimer rows. We calculate the zero bias conductance of these surface states under flat-band condition and find that conduction along the dimer row direction is significant due to strong orbital hybridization. We also find that the surface conductance is orders of magnitude higher than the bulk conductance close to the band edges for the unpassivated surface at room temperature. Therefore, we propose that the transport through these surface states may be the dominant conduction mechanisms in the recently reported scanning tunneling microscopy of silicon nanomembranes. We also calculate the zero bias conductance under flat-band condition for the weakly interacting dangling bond wires along and perpendicular to the dimer row direction and find similar trends. Extended Huckel theory is used for the electronic structure calculations, which is benchmarked with the GW approximation for Si and has been successfully applied to Si systems in past.

description: Due to the limited participation of women in study and business disciplines related to the scientific fields of Physics, Mathematics, Technology and Engineering, the interest in the investigation of gender and STEM has been strongly grown up in recent decades. The purpose of this work is an exploration in the relationship gender - STEM, focusing on the role of education and more specifically, on the teacher / educator. The present study therefore deals with primary school teachers by investigating their perceptions and their level of awareness on various issues arising from gender and STEM. Along with the investigation process, this work aims to inform teachers about these issues through the projection of a series of audiovisual narratives (videos), whose goles are to enrich the participants' minds, make them realize some stereotypical perceptions they hold about the sexes (if they exist) and to overthrow them. The processes of both investigating and informing / sensitizing teachers were done using the same methodological tool that was tailored to meet the specific needs of research and maintains an original structure

description: The temperature dependence of quantum Hall conductivities is studied in the context of the AdS/CMT paradigm using a model with a bulk theory consisting of (3+1)-dimensional Einstein-Maxwell action coupled to a dilaton and an axion, with a negative cosmological constant. We consider a solution which has a Lifshitz like geometry with a dyonic black-brane in the bulk. There is an $Sl(2,R)$ action in the bulk corresponding to electromagnetic duality, which maps between classical solutions, and is broken to $Sl(2,Z)$ by Dirac quantisation of dyons. This bulk $Sl(2,Z)$ action translates to an action of the modular group on the 2-dimensional transverse conductivities. The temperature dependence of the infra-red conductivities is then linked to modular forms via gradient flow and the resulting flow diagrams show remarkable agreement with existing experimental data on the temperature flow of both integral and fractional quantum Hall conductivities.

description: Η βάση και το θεμέλιο της Πολιτείας του Πλάτωνα είναι να αποδειχτεί πως η ευτυχία και η δικαιοσύνη συνταυτίζονται. Προαπαιτούμενο αυτής της απόδειξης είναι ο ορισμός των σχετικών εννοιών και δη της δικαιοσύνης. Στο πρώτο βιβλίο του έργου ο Σωκράτης αναιρεί τους ορισμούς που διατυπώνουν ο Πολέμαρχος και ο Θρασύμαχος με μια ειρωνική διάθεση. Στο δεύτερο βιβλίο οι αδερφοί του Πλάτωνα, Γλαύκων και Αδείμαντος, προτείνουν να συγκριθεί η ευτυχία του δίκαιου και του άδικου ανθρώπου, ώστε να οδηγηθούν στον ορισμό της δικαιοσύνης καθαυτής. Στο τρίτο και τέταρτο βιβλίο του έργου πλέον ο λόγος δίνεται εξ ολοκλήρου στον Σωκράτη, ο οποίος εξ αρχής θεωρεί πως η έννοια της δικαιοσύνης πρέπει να εξεταστεί στο πλαίσιο μιας οργανωμένης κοινωνίας, μιας Πολιτείας. Ιδιαίτερη σημασία δίνεται στην εκπαίδευση και τη διαβίωση των «φυλάκων», η οποία πρέπει να διέπεται από τις τρεις βασικές αρετές, σοφία, ανδρεία, σωφροσύνη. οι τρεις αυτές αρετές συνάπτονται εσωτερικά μόνο με την αρωγή της δικαιοσύνης. Ο Σωκράτης καταληκτικά ερευνά και την ψυχή, την οποία διακρίνει σε τρία μέρη. Πάνω σε αυτή την τριμερή διαίρεση της ψυχής θα δομήσει ο φιλόσοφος και την επιχειρηματολογία του σχετικά με τον τελικό ορισμό της δικαιοσύνης
description: The basis and foundation of the Plato Republic is to prove that happiness and justice are matched. A prerequisite for this proof is the definition of relevant concepts, in particular justice. In the first book of his work Socrates denies the definitions made by the Polemarchus and Thrasymachus with an ironic mood. In the second book, the brothers of Plato, Glaucon and Adeimantus suggest that the happiness of the righteous and the unjust man be compared to lead to the definition of justice as such. In the third and fourth book of the work, the reason is entirely given to Socrates, who, from the outset, considers that the concept of justice must be considered in the context of an organized society, a state. Particular importance is attached to the education and living of "guardians", which must be governed by the three basic virtues, wisdom, prowess, prudence. These three virtues are internalized only with the help of justice. Socrates finally investigates the soul, which he discerns in three parts. On this tripartite division of the soul will be built his philosopher and his arguments on the final definition of justice

description: We present Spitzer Space Telescope images of the isolated dwarf galaxy UGC 10445. The galaxy is detected at all photometric bands (3.6-160um) as well as in the Multiband Imaging Photometer for Spitzer (MIPS) spectral energy distribution mode (55-95um). We derive a star formation rate of 0.25 M_sun/yr based on H-alpha and infrared flux densities. There is over 10^6 solar masses of cold dust (T~18K) in the galaxy, represented by 160um emission, that extends to a larger radius than the ultraviolet (UV), optical and near-infrared light. Such extended emission has been seen previously only in dwarf galaxies in cluster environments. We suggest the source of heating for this dust is UV light originating in star forming complexes. To produce the large quantity of dust requires a higher rate of star formation in the past than is observed currently.

description: Σκοπός της παρούσας μελέτης ήταν να μεταφράσουμε, να προσαρμόσουμε πολιτιστικά και να επικυρώσουμε για τον ελληνικό εφηβικό πληθυσμό με συγκλεισιακές ανωμαλίες τα ερωτηματολόγια MIQ και CPQ11-14 ISF-16 που αξιολογούν την ποιότητα ζωής που σχετίζεται με τη στοματική υγεία. Για το σκοπό αυτό, το ήδη επικυρωμένο για τον ελληνικό πληθυσμό ερωτηματολόγιο OHIP-14 χρησιμοποιήθηκε ως ερωτηματολόγιο αναφοράς. Μετά από τη γραπτή συγκατάθεση των κηδεμόνων τους, 200 νεαρά άτομα ηλικίας 10-16 ετών που μιλούσαν καλά την ελληνική γλώσσα και προσήλθαν για αρχική εξέταση στη Μεταπτυχιακή Ορθοδοντική Κλινική της Οδοντιατρικής Σχολής του Αριστοτελείου Πανεπιστημίου Θεσσαλονίκης, συμπλήρωσαν τις ελληνικές εκδοχές των ερωτηματολογίων MIQ, CPQ11-14 ISF-16 και OHIP-14. Σαράντα άτομα συμπλήρωσαν τα ίδια ερωτηματολόγια ξανά μετά από 3 εβδομάδες προκειμένου να ελεγχθεί η επαναληψιμότητα των μετρήσεων. Βάσει των αποτελεσμάτων της παρούσας μελέτης μπορεί να συναχθεί το συμπέρασμα ότι οι ελληνικές εκδοχές των ερωτηματολογίων MIQ και CPQ11-14 ISF-16 φαίνεται να παρουσιάζουν καλές ιδιότητες όσον αφορά την εγκυρότητα και την αξιοπιστία τους και αποτελούν αξιόπιστα μέσα για την αξιολόγηση της ποιότητας ζωής που σχετίζεται με τη στοματική υγεία σε Έλληνες εφήβους. Ωστόσο, τα ευρήματα αυτά θα πρέπει να ερμηνεύονται με κάποια επιφύλαξη και η γενίκευση τους να περιορίζεται μόνο σε πληθυσμό με χαρακτηριστικά παρόμοια με αυτά του δείγματος της μελέτης. Απαιτείται περαιτέρω δοκιμή των ερωτηματολογίων σε διαφορετικά περιβάλλοντα, συμπεριλαμβανομένων των ιδιωτικών ορθοδοντικών ιατρείων
description: The aim of the present thesis was to translate, culturally adapt and validate for the Greek adolescent population with malocclusion the MIQ and CPQ11-14 ISF-16 instruments, which assess OHRQoL. For this purpose the already validated for Greek population OHIP-14 questionnaire was used to investigate criterion validity. After informed consent, 200 native Greek speakers aged 10-16 seeking for orthodontic treatment at the Postgraduate Orthodontic Clinic of the School Dentistry, Faculty of Health Sciences, Aristotle University of Thessaloniki, completed the Greek versions of the MIQ, CPQ11–14 ISF-16 and OHIP-14. Forty adolescents completed the same questionnaires again after 3 weeks in order to test the repeatability of the measurements. Based on the results of this study it can be concluded that the Greek versions of MIQ and CPQ11-14 ISF-16 may exhibit good properties in terms of validity and reliability and seem to be reliable instruments to assess Oral Health-Related Quality of Life in Greek adolescents. Nevertheless, these findings should be interpreted with some caution and their generalization might be limited only to a population with characteristics similar to the study’s sample. Further testing of the measures is required in a variety of environments, including specialist orthodontic practices

description: The relative abundance of alpha particles with respect to proton, usually expressed as $A_{He}$ = ($n_α/n_p$)*100, is known to respond to solar activity although changes in its behaviour in the last four solar cycles are not known. In this letter, by systematically analysing inter-calibrated $A_{He}$ data obtained from the first Lagrangian point of the Sun-Earth system, we show that $A_{He}$ variations are distinctively different in solar cycle 24 as compared to the last three cycles. The frequency of $A_{He}$ = 2-3% events is significantly higher in slow/intermediate solar winds in cycle 24 as opposed to the dominance of the typical $A_{He}$ = 4-5% events in the previous three cycles. Further, the occurrence of $A_{He}$ $\geq$ 10% events is significantly reduced in cycle 24. Not only that, the changes in delay of $A_{He}$ with respect to peak sunspot numbers are less sensitive to changes in solar wind velocity in cycle 24. The investigation suggests that the coronal magnetic field configuration started undergoing systematic changes starting from cycle 23 and this altered magnetic field configuration affected the way helium got processed and depleted in the solar atmosphere.

description: We analyze evolution of gravitational perturbations of D-dimensional Schwarzschild, Reissner-Nordström, and Reissner-Nordstrom-de Sitter black holes. It is known that the effective potential for the scalar type of gravitational perturbations has negative gap near the event horizon. This gap, for some values of the parameters Q (charge), Lambda (cosmological constant) and D (number of space-time dimensions), cannot be removed by S-deformations. Thereby, there is no proof of (in)stability for those cases. In the present paper, by an extensive search of quasinormal modes, both in time and frequency domains, we shall show that spherically symmetric static black holes with arbitrary charge and positive (de Sitter) lambda-term are stable for D=5, 6, >...11. In addition, we give a complete numerical data for all three types (scalar, vector and tensor) of gravitational perturbations for multi-dimensional black holes with charge and Lambda-term. The influence of charge, Lambda-term and number of extra dimensions on black hole quasinormal spectrum is discussed.

Ideologia y humor en La Dama Boba de Lope de Vega y Carpio
Creators: name: Salvador, Gines
Publisher: name: University of British Columbia
Year: 2008

description: This study attempts to analyze Lope de Vega's La dama boba (1613), The study begins with a brief review of the literature on La dama boba and a few notes on the methodology used to interpret the play. Vis-a-vis this existing body of critical literature, the objective of this thesis is to follow the play on a scene by scene basis, thus viewing the work as intended by its author. As a corollary to that objective, careful attention will be placed on the author's ideological viewpoint. In this play Lope applies basic principles of platonism, aristotelianism and neoplatonism to common domestic affairs. Thus we see how "love" can transform a foolish young woman (boba) into a crafty and astute person (lista), or how "extremes" in character—the fool, the pedant--will ultimately find their "golden mean." Lope manages to portray this philosophical vision while at the same time maintaining the interest of his audience through humour. Therefore the study also examines some of the mechanisms of humour used by the playwright.
