description: The determination of the brown dwarf binary fraction may contribute to the understanding of the substellar formation mechanisms. Unresolved brown dwarf binaries may be revealed through their peculiar spectra or the discrepancy between optical and near-infrared spectral type classification. We obtained medium-resolution spectra of 22 brown dwarfs with these characteristics using the X-Shooter spectrograph at the VLT. We aimed to identify brown dwarf binary candidates, and to test if the BT-Settl 2014 atmospheric models reproduce their observed spectra. To find binaries spanning the L-T boundary, we used spectral indices and compared the spectra of the selected candidates to single spectra and synthetic binary spectra. We used synthetic binary spectra with components of same spectral type to determine as well the sensitivity of the method to this class of binaries. We identified three candidates to be combination of L plus T brown dwarfs. We are not able to identify binaries with components of similar spectral type. In our sample, we measured minimum binary fraction of $9.1^{+9.9}_{-3.0}$. From the best fit of the BT-Settl models 2014 to the observed spectra, we derived the atmospheric parameters for the single objects. The BT-Settl models were able to reproduce the majority of the SEDs from our objects, and the variation of the equivalent width of the RbI (794.8 nm) and CsI (852.0 nm) lines with the spectral type. Nonetheless, these models did not reproduce the evolution of the equivalent widths of the NaI (818.3 nm and 819.5 nm) and KI (1253 nm) lines with the spectral type.

Locke, toleration, and God's providence
Creators: name: Jacobs, A. I.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: This essay is an exploration of some of the theological dimensions of Locke's theory of toleration. First, I argue that the skepticism that is often associated with Locke's argument against religious coercion would have been unintelligible to Locke and his contemporaries. Second, I offer an alternative reading of Locke's theory based upon his exchange with Jonas Proast. I argue that by examining the debate between Locke and Proast, one can see that Locke's theory rested upon his conception of providentialism, specifically the distinction between God's ordinary and extraordinary providence. In my view, it was Locke's belief that God would not fail to provide the means for human salvation that allowed him to contend that beliefs incapable of rational assessment fall outside the jurisdiction of the magistrate. Finally, I conclude with some general thoughts on the implications of a providential reading of Locke for interpretations of the early enlightenment.

description: Microscopic properties of low-energy spin dynamics in diluted magnetic semiconductor are addressed in a framework of the Kondo lattice model including random distribution of magnetic dopants. Based on the fluctuation-dissipation theorem, we derive an explicit dependence of the spin diffusion coefficient on the single-particle Green function which is directly evaluated by dynamical mean-field theory. In the paramagnetic state, the magnetic scattering has been manifested to suppress spin diffusion. In agreement with other ferromagnet systems, we also point out that the spin diffusion in diluted magnetic semiconductors at small carrier concentration displays a monotonic $1/T$-like temperature dependence. By investigating the spin diffusion coefficient on a wide range of the model parameters, the obtained results have provided a significant scenario to understand the spin dynamics in the paramagnetic diluted magnetic semiconductors.

description: The project Death and Burial Data: Ireland 1864-1922 (DBDIrl) examines the relationship between historical death registration data and burial data to explore the history of power in Ireland from 1864 to 1922. Its core Big Data arises from historical records from a variety of heterogeneous sources, some aspects are pre-digitized and machine readable. A huge data set (over 4 million records in each source) and its slow manual enrichment (ca 7,000 records processed so far) pose issues of quality, scalability, and creates the need for a quality assurance technology that is accessible to non-programmers. An important goal for the researcher community is to produce a reusable, high-level quality assurance tool for the ingested data that is domain specific (historic data), highly portable across data sources, thus independent of storage technology. This paper outlines the step-wise design of the finer granular digital format, aimed for storage and digital archiving, and the design and test of two generations of the techniques, used in the first two data ingestion and cleaning phases. The first small scale phase was exploratory, based on metadata enrichment transcription to Excel, and conducted in parallel with the design of the final digital format and the discovery of all the domain-specific rules and constraints for the syntax and semantic validity of individual entries. Excel embedded quality checks or database-specific techniques are not adequate due to the technology independence requirement. This first phase produced a Java parser with an embedded data cleaning and evaluation classifier, continuously improved and refined as insights grew. The next, larger scale phase uses a bespoke Historian Web Application that embeds the Java validator from the parser, as well as a new Boolean classifier for valid and complete data assurance built using a Model-Driven Development technique that we also describe. This solution enforces property constraints directly at data capture time, removing the need for additional parsing and cleaning stages. The new classifier is built in an easy to use graphical technology, and the ADD-Lib tool it uses is a modern low-code development environment that auto-generates code in a large number of programming languages. It thus meets the technology independence requirement and historians are now able to produce new classifiers themselves without being able to program. We aim to infuse the project with computational and archival thinking in order to produce a robust data set that is FAIR compliant (Free Accessible Inter-operable and Re-useable)

description: We investigate extremal problems for hypergraphs satisfying the following density condition. A $3$-uniform hypergraph $H=(V, E)$ is $(d, η,P_2)$-dense if for any two subsets of pairs $P$, $Q\subseteq V\times V$ the number of pairs $((x,y),(x,z))\in P\times Q$ with $\{x,y,z\}\in E$ is at least $d|\mathcal{K}_{P_2}(P,Q)|-η|V|^3,$ where $\mathcal{K}_{P_2}(P,Q)$ denotes the set of pairs in $P\times Q$ of the form $((x,y),(x,z))$. For a given $3$-uniform hypergraph $F$ we are interested in the infimum $d\geq 0$ such that for sufficiently small $η$ every sufficiently large $(d, η,P_2)$-dense hypergraph $H$ contains a copy of $F$ and this infimum will be denoted by $π_{P_2}(F)$. We present a few results for the case when $F=K_k^{(3)}$ is a complete three uniform hypergraph on $k$ vertices. It will be shown that $π_{P_2}(K_{2^r}^{(3)})\leq \frac{r-2}{r-1}$, which is sharp for $r=2,3,4$, where the lower bound for $r=4$ is based on a result of Chung and Graham [Edge-colored complete graphs with precisely colored subgraphs, Combinatorica 3 (3-4), 315-324].

Anchoring the design process

description: This thesis proposes a framework to address the design process in design education. Building upon the assumption that teachers, being professional designers, do not discuss the design process in the architectural design studio and do not have a vocabulary to do so, five generic elements or anchor points are defined which represent the basic design skills. The validity of the framework and the assumption is tested respectively in interviews with a variety of designers and in observations of dialogues between teachers and students. In the final test the design process is addressed in the design studio: the first experiences show that students’ understanding and self-efficacy may increase. The five elements enable teachers and students to address the designerly attitude. The way designers reason consist of: (1) experimentation; an experimentation-based way of thinking; how to explore and reflect, (2) the frame of reference; a knowledge-based way of thinking; how to work with common and proven ‘professional’ knowledge, and (3) the guiding theme; a value-based way of thinking; how to take a position in the design process. Next to that, (4) the laboratory is the (visual) language or set of means designers use to think designerly, and (5) the domains are the playing field of the designer, the product aspects s/he should address.

description: In this paper, we analyze the complexity of functional programs written in the interaction-net computation model, an asynchronous, parallel and confluent model that generalizes linear-logic proof nets. Employing user-defined sized and scheduled types, we certify concrete time, space and space-time complexity bounds for both sequential and parallel reductions of interaction-net programs by suitably assigning complexity potentials to typed nodes. The relevance of this approach is illustrated on archetypal programming examples. The provided analysis is precise, compositional and is, in theory, not restricted to particular complexity classes.

description: We study the fragmentation fractions $(f_{{\bf B}_b})$ of the $b$-quark to b-baryons (${\bf B}_b$). By the assumption of $f_{Λ_b}/(f_u+f_d)=0.25\pm 0.15$ in accordance with the measurements by LEP, CDF and LHCb Collaborations, we estimate that $f_{Λ_b}=0.175\pm 0.106$ and $f_{Ξ_b^{-,0}}=0.019\pm 0.013$. From these fragmentation fractions, we derive ${\cal B}(Λ_b\to J/ψΛ)=(3.3\pm 2.1)\times 10^{-4}$, ${\cal B}(Ξ_b^-\to J/ψΞ^-)=(5.3\pm 3.9)\times 10^{-4}$ and ${\cal B}(Ω_b^-\to J/ψΩ^-)>1.9\times 10^{-5}$. The predictions of ${\cal B}(Λ_b\to J/ψΛ)$ and ${\cal B}(Ξ_b^-\to J/ψΞ^-)$ clearly enable us to test the theoretical models, such as the QCD factorization approach in the $b$-baryon decays.

Sedna and the cloud of comets surrounding the Solar System in Milgromian dynamics

description: We reconsider the hypothesis of a vast cometary reservoir surrounding the Solar System - the Oort cloud of comets - within the framework of Milgromian Dynamics (MD or MOND). For this purpose we built a numerical model of the cloud assuming QUMOND, a modified gravity theory of MD. In the modified gravity versions of MD, the internal dynamics of a system is influenced by the external gravitational field in which the system is embedded, even when this external field is constant and uniform, a phenomenon dubbed the external field effect (EFE). Adopting the popular pair $ν(x)=[1-\exp(-x^{1/2})]^{-1}$ for the MD interpolating function and $a_{0}=1.2\times10^{-10}$ m s$^{-2}$ for the MD acceleration scale, we found that the observationally inferred Milgromian cloud of comets is much more radially compact than its Newtonian counterpart. The comets of the Milgromian cloud stay away from the zone where the Galactic tide can torque their orbits significantly. However, this does not need to be an obstacle for the injection of the comets into the inner solar system as the EFE can induce significant change in perihelion distance during one revolution of a comet around the Sun. Adopting constraints on different interpolating function families and a revised value of $a_{0}$ (provided recently by the Cassini spacecraft), the aforementioned qualitative results no longer hold, and, in conclusion, the Milgromian cloud is very similar to the Newtonian in its overall size, binding energies of comets and hence the operation of the Jupiter-Saturn barrier. However, EFE torquing of perihelia still play a significant role in the inner parts of the cloud. Consequently Sedna-like orbits and orbits of large semi-major axis Centaurs are easily comprehensible in MD. In MD, they both belong to the same population, just in different modes of their evolution.

description: Electrodynamics with a local and linear constitutive law is used as a framework for models violating Lorentz covariance. The constitutive tensor of such a construction is irreducibly decomposed into three independent pieces. The principal part is the anisotropic generalisation of the standard electrodynamics. The two other parts, axion and skewon, represent non-classical modifications of electrodynamics. We derive the expression for the photon propagator in the Minkowski spacetime endowed with a skewon field. For a relatively small (antisymmetric) skewon field, a modified Coulom law is exhibited.

description: Aims: To investigate the antibacterial effects of ozone on Streptococcus mutans in vitro. Methods: A bacteria volume of 106 CFU/ml was inoculated on human and bovine dentin specimens and in Wilkins-Chalgren broth media (WC, Difco Laboratories. Sparks) treated with two ozone sources (Curozone X4®, Kavo; OL80A and OL80W, Yanco Industries), at various concentrations (2, 20, 200, 2000 and 2100 ppm) and exposure times (from 15 sec to 4 min). Results: Curozone X4 had no effect on bacteria recovery, while OL80A and OL80W showed a concentration-dependent effect on S. mutans recover on a Trypticase™ Soy Agar with 5% Sheep Blood (Difco Laboratories. Sparks). Concentrations of 200 and 2000 ppm showed no bacteria recovery after treatment for 4 min, while 2 and 20 ppm showed significant reduction of the recovered bacteria. Conclusions: This study suggests that Curozone X4® generator is not capable of delivering ozone to would effectively disinfect a caries lesion.

description: We present a comparative ab initio study of Li, Na, and Mg storage in tin, including phononic effects and phase competition between alpha and beta Sn. Mg doping at low concentration is found to stabilize the beta phase. On the contrary, Li and Na doping is shown to reverse the stability of the phases at room temperature: Li/Na-doped alpha-Sn is more stable than Li/Na-doped beta-Sn up to a temperature of around 380/400 K. This may rationalize the formation of alpha-Sn upon lithiation and delithiation of beta-Sn anodes reported in experimental studies. The changes in phase stability with Li/Na/Mg doping are directly related to the intercalation energies of Li/Na/Mg in one phase versus the other: at 300 K, Li/Na is easier intercalated in alpha-Sn (-0.37/-0.08 eV) than in beta-Sn (0.06/0.49 eV), while Mg intercalation energy is, although positive (i.e. unfavored intercalation), lower in beta-Sn (0.53 eV) than in alpha-Sn (0.66 eV). The temperature effect is found to affect significantly the intercalation energy, by up to 0.13 eV at 300 K. Analysis of diffusion barriers shows that Li, Na, and Mg diffusion in beta-Sn is anisotropic with migration barriers along the (001) direction (respectively 0.01, 0.22, and 0.07 eV) significantly lower than those in alpha-Sn (respectively 0.20, 0.52, and 0.40 eV).

Goldstone Boson Interaction in D=2+1 (Pseudo-)Lorentz-Invariant Systems with a Spontaneously Broken Internal Rotation Symmetry

description: The low-temperature properties of systems characterized by a spontaneously broken internal rotation symmetry, O($N$) $\to$ O($N$-1), are governed by Goldstone bosons and can be derived systematically within effective Lagrangian field theory. In the present study we consider systems living in two spatial dimensions, and evaluate their partition function at low temperatures up to three-loop order. Although our results are valid for any such system, here we use magnetic terminology, i.e., we refer to quantum spin systems. We discuss the sign of the Goldstone boson interaction in the pressure, staggered magnetization, and susceptibility as a function of an external staggered field for general $N$. As it turns out, the $d$=2+1 quantum XY model ($N$=2) and the $d$=2+1 Heisenberg antiferromagnet ($N$=3), are rather special, as they represent the only cases where the spin-wave interaction in the pressure is repulsive in the whole parameter regime where the effective expansion applies. Remarkably, the $d$=2+1 XY model is the only system where the interaction contribution in the staggered magnetization (susceptibility) tends to positive (negative) values at low temperatures and weak external field.

description: Light and spectroscopy are among the most important and frequently taught topics in introductory, college-level, general education astronomy courses. This is due to the fact that the vast majority of observational data studied by astronomers arrives at Earth in the form of light. While there are many processes by which matter can emit and absorb light, Astro 101 courses typically limit their instruction to the Bohr model of the atom and electron energy level transitions. In this paper, we report on the development of a new Lecture-Tutorial to help students learn about other processes that are responsible for the emission and absorption of light, namely molecular rotations, molecular vibrations, and the acceleration of charged particles by magnetic fields.

description: Periodic driving of a quantum system can enable new topological phases with no analog in static systems. In this paper we systematically classify one-dimensional topological and symmetry-protected topological (SPT) phases in interacting fermionic and bosonic quantum systems subject to periodic driving, which we dub Floquet SPTs (FSPTs). For physical realizations of interacting FSPTs, many-body localization by disorder is a crucial ingredient, required to obtain a stable phase that does not catastrophically heat to infinite temperature. We demonstrate that bosonic and fermionic FSPTs phases are classified by the same criteria as equilibrium phases, but with an enlarged symmetry group $\tilde G$, that now includes discrete time translation symmetry associated with the Floquet evolution. In particular, 1D bosonic FSPTs are classified by projective representations of the enlarged symmetry group $H^2({\tilde G},U(1))$. We construct explicit lattice models for a variety of systems, and then formalize the classification to demonstrate the completeness of this construction. We also derive general constraints on localization and symmetry based on the representation theory of the symmetry group, and show that symmetry-preserving localized phases are possible only for Abelian symmetry groups. In particular, this rules out the possibility of many-body localized SPTs with continuous spin symmetry.

We give an analytic proof of this fact checking the properties of the differential Galois group of the system's variational equations along a particular non-equilibrium solution.

Immigration and naturalization policies in Germany: changing the way we examine the development of Turkish immigrants
Creators: name: Denison, Randall Charles
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Turkish immigrants, residing in Germany, claim that the development of immigration and naturalization policies in conjunction with violent acts made by extremists is valid evidence that German nationals are motivated by racial prejudice. Consequently, they assert that individuals descending from Turkish ancestry are coerced to fully integrate into the national culture and transform themselves into ideal Germans. The study of ethnocentric intolerance in Germany is not a new issue in political science, but rather a long-term commitment to investigating and understanding the nature of social relations in the German Federal Republic. The conventional wisdom argues that the arrival and subsequent entrenchment of Turkish immigrants produced concern for economic competitiveness among German nationals. Under the belief that Turkish immigrants would easily obtain employment at lower wages and that they would request social assistance from the state, Germans would become increasingly intolerant and discriminatory towards all ethnic minorities, most especially Turks. I contend that the conventional wisdom fails to provide a sufficient causal explanation for the occurrence of ethnocentric intolerance. I find that while self-interest influences social relations, the relationship between Turks and Germans is not simply predicated on a conflict of economic interests. I also contend that a sufficient causal explanation for German-Turkish relations must take into consideration at least four variables: national identity, technocratic institutions, racial prejudice, and self-interest.

Among other mechanisms, 2 immediate satisfaction survey questionnaires were developed and data collection occured in the following instances: Local space initiatives of the 1st pilot round: The first questionnaire was circulated at the end of the events of "Space Coffee" initiatives deployed in Greece, Romania and Croatia (1st pilot round), that assess the events themselves, as well as other services of the InnORBIT project with which event participants interacted. Regional partners COR, ROS and ALG supported data collection in their respective regions. InnORBIT training programme: The second questionnaire was offered to users of the InnORBIT learning platform following the completion of various modules or courses. The e-learning platform offers business and technical space training for innovation intermediaries' personnel (Capacity Building Programme) and space innovators such as entrepreneurs, start-ups, students, SMEs (Business Support Programme). The data collected through monitoring and evaluation activities were compiled into a spreadsheet, along with metadata and the question list of the immediate satisfaction surveys.

description: The quantum groups of finite and affine type $A$ admit geometric realizations in terms of partial flag varieties of finite and affine type $A$. Recently, the quantum group associated to partial flag varieties of finite type $B/C$ is shown to be a coideal subalgebra of the quantum group of finite type $A$. In this paper we study the structures of Schur algebras and Lusztig algebras associated to (four variants of) partial flag varieties of affine type $C$. We show that the quantum groups arising from Lusztig algebras and Schur algebras via stabilization procedures are (idempotented) coideal subalgebras of quantum groups of affine $\mathfrak{sl}$ and $\mathfrak{gl}$ types, respectively. In this way, we provide geometric realizations of eight quantum symmetric pairs of affine types. We construct monomial and canonical bases of all these quantum (Schur, Lusztig, and coideal) algebras. For the idempotented coideal algebras of affine $\mathfrak{sl}$ type, we establish the positivity properties of the canonical basis with respect to multiplication, comultiplication and a bilinear pairing. In particular, we obtain a new and geometric construction of the idempotented quantum affine $\mathfrak{gl}$ and its canonical basis.

Disappearing Inflaton Potential via Heavy Field Dynamics

description: We propose a possibility that the inflaton potential is significantly modified after inflation due to heavy field dynamics. During inflation there may be a heavy scalar field stabilized at a value deviated from the low-energy minimum. As the heavy field moves to the low-energy minimum, the inflaton potential could be significantly modified. In extreme cases, the inflaton potential vanishes and the inflaton becomes almost massless at some time after inflation. Such transition of the inflaton potential has interesting implications for primordial density perturbations, reheating, creation of unwanted relics, dark radiation, and experimental search for light degrees of freedom. To be concrete, we consider a chaotic inflation in supergravity where the inflaton mass parameter is promoted to a modulus field, finding that the inflaton becomes stable after the transition and contributes to dark matter. Another example is the new inflation by the MSSM Higgs field which acquires a large expectation value just after inflation, but it returns to the origin after the transition and settles down at the electroweak vacuum. Interestingly, the smallness of the electroweak scale compared to the Planck scale is directly related to the flatness of the inflaton potential.

The psychosocial and psychosexual impact of this disease is influenced by a number of factors including medical factors, individual factors, and relationship factors. Overall, breast cancer treatments (medical factors) did not disrupt sexual functioning or body image. Instead, depression and fatigue (individual factors) were found to impact women's sexual functioning, and depression was related to women's own body image as well as how she perceived her male partner to view her body. Lastly, women's perceptions of their male partners' view of their bodies (relationship factor) were related to the women's own body image and marital satisfaction. Results suggest a more optimistic view regarding the anticipated negative consequences of a breast cancer diagnosis.

description: Η κοινωνική ασφάλιση είναι ένας θεσμός δικαίου, είναι μία έκφανση της αλληλεγγύης μεταξύ των μελών μιας κοινωνίας, είναι ένα εργαλείο αναδιανομής του πλούτου και είναι η βασική απάντηση σε μια σειρά από κινδύνους που θα αντιμετωπίσουμε, αναπόφευκτα, όλοι σε κάποιο σημείο της ζωής μας. Στην Ελλάδα όμως, η κοινωνική ασφάλιση είχε έναν διττό χαρακτήρα: υπήρξε ο βασικός πυλώνας της ευρύτερης κοινωνικής ασφάλειας όπως στην πλειονότητα των ευρωπαϊκών χωρών αλλά υπήρξε και ένα πεδίο ευνοιοκρατίας, πελατειακών σχέσεων και άσκησης αφανών πολιτικών που είχαν ως αποτέλεσμα τον κατακερματισμό του συστήματος και την ανισότητα στις παροχές ενώ ταυτόχρονα υπέσκαπταν την επάρκεια και τη βιωσιμότητα του οικοδομήματος. Η παρούσα εργασία ασχολείται με την εξέλιξη της κοινωνικής ασφάλισης, τόσο σε διεθνές όσο και σε τοπικό επίπεδο, αλλά φιλοδοξεί να τονίσει και κάποιες πτυχές της που διαμορφώθηκαν από την επιρροή της πολιτικής διαφθοράς. Επίσης, υπό το πρίσμα της εξελικτικής πορείας της κοινωνικής ασφάλισης στην Ελλάδα, των δυνάμεων που της έδωσαν τη σημερινή μορφή της αλλά και των προκλήσεων της σύγχρονης εποχής, εξετάζεται το παρόν αλλά και το μέλλον της κοινωνικής ασφάλισης.

description: In this paper, we give a concrete description of the two-fold cover of a simply connected, split real reductive group and its maximal compact subgroup as Chevalley groups. We define a representation of the maximal compact subgroup called pseudospherical representation, it appears with multiplicity one in the principal series representation. We introduce a family of canonically defined intertwining operators and compute the action of them on pseudospherical K-types, obtaining explicit formulas of the Harish-Chandra c-function.

description: Maternal iron deficiency is a world wide and major public health issue. Despite recent researchers’ interest related to this topic, its impact in the offspring still remains unclear. The aim of this study is to understand the impact of maternal iron deficiency on the auditory functions and serum cortisol levels in the young and adult guinea pig at post-natal day (PNd) 24 and PNd84, respectively. Pregnant guinea pigs were given an iron deficient (ID) or iron sufficient (IS) diet during gestation and lactation. An iron sufficient diet was provided to all pups after weaning day. No significant difference was observed in the hearing threshold and latencies in siblings from both groups at PNd24 and PNd84. However, ID offspring showed a significant higher interpeak latency I-IV at 100 dB than IS pups at PNd24. ID offspring also had significant elevated cortisol levels at PNd24 compared to IS control group. Maternal iron deficiency affects negatively the auditory functions and raises the serum cortisol levels, a biomarker of stress in the offspring.

description: A closed braid naturally gives rise to a transverse link in the standard contact 3-space. We study the effect of the dynamical properties of the braid monodromy, such as right-veering, on the contact-topological properties of the transverse link and its transverse invariants in knot Floer and Khovanov homologies. In particular, we show that a 3-braid is right-veering if and only if the (hat-version of) the Heegaard Floer transverse invariant is non-zero. For higher-index braids, we show that this invariant is non-zero whenever the braid monodromy has the fractional Dehn twist coefficient C>1. These results clarify the qualitative meaning of the transverse invariants; our proofs use grid diagrams and the structure of Dehornoy's braid ordering.

description: Ideology played an extensive role in the post-Cold War insurgencies examined here (the Taliban Movement, in Afghanistan; the Parti pour la Révolution des Peuples, in the Democratic Republic of Congo; and the Revolutionary Armed Forces of Colombia, in Colombia) beyond the discursive level. Ideology served the rhetorical purpose of legitimizing armed struggles, but it also proved crucial to determine the insurgent organizations’ internal structures and their apparatus of power in territories under their control, to shape their governmental policies, and to provide strategic and tactical gains in the battlefield.

description: Η Ελλάδα έχει αντιμετωπίσει αρκετές απότομες αλλαγές ως αποτέλεσμα της σοβαρής οικονομικής κρίσης που υπέστη το έθνος τα τελευταία 10 χρόνια. Οι δημόσιες δαπάνες μειώθηκαν και ένα σημαντικό μέρος των νοικοκυριών οδηγήθηκε στη φτώχεια. Το ποσοστό φτώχειας στην Ελλάδα το 2013 ήταν λίγο πάνω από το 23,1%, σύμφωνα με τη Eurostat. Ο κλάδος της εκπαίδευσης δεν ήταν απρόσβλητος στις αρνητικές επιπτώσεις που επηρέασαν σχεδόν όλες τις κοινωνικές ομάδες. Πολλά από τα απαραίτητα εφόδια που χρειάζονταν για να λειτουργήσουν σωστά τα σχολεία έλειπαν. Η κοινωνικοοικονομική κατάσταση στην οποία βρισκόταν το έθνος επηρέασε επίσης τους μαθητές, καθώς οι γονείς τους ήταν υπό τόση οικονομική πίεση. Άλλωστε, ένας σημαντικός αριθμός γονέων αντιμετώπισε ξαφνική απώλεια εργασίας και πολλοί άλλοι πάλεψαν να βρουν ακόμη και τα πιο βασικά είδη ανάγκης για να επιβιώσουν οι οικογένειές τους. Αναπόφευκτα, τα παιδιά επηρεάστηκαν από την επιδείνωση της οικονομικής κατάστασης. Τέλος, υπήρξαν σημαντικές, σε μεγάλο βαθμό αρνητικές τροποποιήσεις στο επάγγελμα του εκπαιδευτικού. Σκοπός της συγκεκριμένης μελέτης είναι η καταγραφή όλων των αλλαγών που υπέστη η σχολική κοινότητα, η ανάδειξη των στοιχείων που αποδεικνύουν την οικονομική καθίζηση στην κοινωνία μας, στο εκπαιδευτικό σύστημα και κατά κύριο λόγο στους εκπαιδευτικούς που αποτελούν και το δείγμα αυτής της έρευνας. Η μελέτη που πραγματοποιήθηκε απευθύνθηκε σε εκπαιδευτικούς και διευθυντικά στελέχη των σχολικών μονάδων Ζωγράφου, Νέας Ερυθραίας Κηφισιάς, Αμπελοκήπων, Παλαιού Φαλήρου, Βούλας και Πειραιά με βαθύτερο στόχο να καταγράφει η άποψή τους σχετικά με το πόσο επηρεάστηκε η σχολική λειτουργία, οι μαθητές και η σχολική καθημερινότητά τους από την οικονομική κρίση. Τέλος, η έρευνα καταγράφει την γνώμη τους αναφορικά με το αν διακρίνουν οποιαδήποτε βελτίωση τα τελευταία έτη στην εκπαίδευση και πόσο αισιόδοξοι είναι για το μέλλον του εκπαιδευτικού συστήματος.

description: There is a current need to examine collegiate athletes' psychological health. Our study examined the relationship between optimism and psychological health and explored how imagery affects optimism. Division I collegiate varsity and club athletes completed an internet-based questionnaire (including the LOT, SWLS, I-PANAS-SF, and ABQ) as a measurement of psychological health. The experimental group completed an imagery intervention in efforts of altering optimism. Correlational analyses identified associations among optimism and the psychological health outcomes at time one. The repeated measure ANOVA's identified a significant change in optimism in all participants throughout the study but identified no significant change in affect, burnout, and psychological well-being. The study indicated optimism may change. The study did not show clinical implications for using imagery to improve optimism in student-athletes; however it did not indicate any negative effects of providing information about positivity and incorporating imagery into a student-athletes daily life.

description: This work addresses the effect of substituting Mn$^{3+}$ by Fe$^{3+}$ at the octahedral site of TbMnO$_3$ on the magnetic phase sequence, ferroelectric and magnetoelectric properties, keeping the Fe$^{3+}$ concentration below 5%. The temperature dependence of the specific heat, dielectric permittivity and electric polarization was studied as a function of Fe$^{3+}$ concentration and applied magnetic field. From the experimental results a strong decrease of the electric polarization with increasing Fe$^{3+}$ substitution is observed, vanishing above a concentration of 4%. However, within this range, a significant increase of the magnetic sensitivity of the electric polarization is obtained by increasing Fe$^{3+}$ concentration. Above that value, a non-polar, weak ferromagnetic phase emerges, in good agreement with the predictions of the Dzyalowshinskii-Moriya model. This behavior reveals the crucial effect of Fe$^{3+}$ substitution in octahedral sites on the magnetic phase sequence, polar and magnetoelectric behavior of the TbMn$_{1-x}$Fe$_x$O$_3$ system. From the results obtained in this work, it is understood that this behavior is not associated with the eg electronic configuration, but instead to the competition between ferromagnetic and antiferromagnetic interactions, which is very sensitive to both local fields and distortions.

description: Η παρούσα διπλωματική εργασία εκπονήθηκε στα πλαίσια του Προγράμματος Μεταπτυχιακών Σπουδών «Προηγμένα Συστήματα Πληροφορικής - Ανάπτυξη Λογισμικού και Τεχνητής Νοημοσύνης», και έχει ως στόχο την υλοποίηση μίας android εφαρμογής mobile learning, μέσω της οποίας γίνεται η αναγνώριση του τρέχοντος συναισθήματος του χρήστη και συλλέγονται δεδομένα κατά τη διάρκεια της μάθησης. Τα δεδομένα χρησιμοποιούνται είτε αυτούσια, είτε επεξεργάζονται μέσω μοντέλων μηχανικής μάθησης για την εξαγωγή συμπερασμάτων. Σκοπός είναι η παροχή πληροφορίας μέσω analytics στον εκπαιδευτικό, ώστε να μπορεί να εκτιμήσει την απόδοση του κάθε μαθητή, να αξιολογήσει το εκπαιδευτικό περιεχόμενο που έχει δημιουργήσει, καθώς και την μέθοδο διδασκαλίας του. Παρουσιάζονται αρκετά στατιστικά στοιχεία ως παραδείγματα της πληροφορίας που μπορεί να εξαχθεί ατομικά για κάποιον χρήστη ή μαζικά για πολλούς. Τα Analytics διατίθενται μέσω δύο jupyter notebook που δημιουργήσαμε στο Google Colab. Με αυτό τον τρόπο παρέχεται στον εκπαιδευτικό η πρόσβαση στην πληροφορία μαζί με τη δυνατότητα για εύκολη επεξεργασία. Τα analytics που παρουσιάζουμε αποτελούν παραδείγματα από dummy data που εισήχθησαν ενδεικτικά και δεν αποτελούν πραγματικά δεδομένα. Εξάλλου σκοπός είναι να παρουσιαστούν οι διαφορετικές πληροφορίες που μπορούν να εξαχθούν και όχι να τις αξιοποιήσουμε για να βγάλουμε συμπεράσματα για την μάθηση μέσω κινητού. Τέλος πρέπει να αναφέρουμε έναν ακόμα στόχο της συγκεκριμένης διπλωματικής, ο οποίος είναι να δείξει τον τρόπο και την ευκολία με την οποία ένα κινητό τηλέφωνο μπορεί να συλλέξει δεδομένα και να τα αναλύσει σε πραγματικό χρόνο. Αυτό γίνεται εφικτό μέσω των πολλών διαφορετικών API που παρέχονται ελεύθερα στον προγραμματιστή από την Google.
