description: Στην παρούσα εργασία, μελετήθηκαν γεωχημικά συνολικά 31 δείγματα θρυμμάτων από 4 υπεράκτιες γεωτρήσεις μεγάλου βάθους, από την θαλάσσια περιοχή του Β. Αιγαίου και συγκεκριμένα από το κοίτασμα ‘’Πρίνος’’ στην θαλάσσια περιοχή της Καβάλας-Θάσου. Τα δείγματα ήταν ‘’πλυμένα’’, δηλαδή είχαν απαλλαχθεί από τον πολφό διάτρησης, ο οποίος αποτελείται από ένα μίγμα νερού, μπεντονίτη, βαρύτη και διάφορων πρόσθετων κατά περίπτωση. Όπως φάνηκε από τις αναλύσεις, μεγάλη ποσότητα του βαρύτη παρέμεινε στα δείγματα, δίνοντας μεγάλα ποσοστά για το οξείδιο του βαρίου (1-10%). Οι αναλύσεις που πραγματοποιήθηκαν ήταν η περιθλασιμετρία ακτινών Χ και η φασματομετρία φθορισμού ακτινών Χ, ενώ πραγματοποιήθηκε θέρμανση μέρους των δειγμάτων σε υψηλή θερμοκρασία (1050oC) για το υπολογισμό της απώλειας πύρωσης. Τέλος, σύμφωνα με τα αποτελέσματα, εξήχθησαν συμπεράσματα για την εξέλιξη της διαγένεσης στην λεκάνη, την λιθολογία των δειγμάτων και την αρχική περιεκτικότητα σε οργανική ύλη
description: The present thesis deals with the geochemical study of 31 cuttings sample from 4 offshore deep wells from the marine region of N. Aegean sea and in particular from ‘’Prinos’’ field in the marine region of Kavala-Thassos. The samples were ‘’washed’’, meaning that they were relieved from the drilling mud which consists of water, bentonite, baryte and various other additives. As shown in the analysis, large quantity of baryte remained in the sample giving large barium oxide record (1-10%). The analyzes conducted were X ray diffraction and X ray fluorescence, while heating part of the samples at high temperature (1050oC) took place in order to calculate the Loss of Ignition (LoI). Finally, according to the results, conclusions were extracted for the basin’s diagenetic evolution, lithology of the samples and the initial organic matter content

description: We show that the gravitino-overproduction problem is prevalent among inflation models in supergravity. An inflaton field generically acquires (effective) non-vanishing auxiliary field, if the Kahler potential is non-minimal. The inflaton field then decays into a pair of the gravitinos, thereby severely constraining many of the inflation models especially in the case of the gravity-mediated SUSY breaking.

Εξετάσαμε τις έννοιες του μύθου και της διακειμενικότητας σε μια προσπάθεια να τις συσχετίσουμε με την τραγωδία. Στη συνέχεια παρουσιάσαμε τις έννοιες της εξουσίας και του ηθικού καθήκοντος. Ακόμη αναφερθήκαμε αναλυτικά στην Αντιγόνη του Σοφοκλή αλλά και στα έργα των Anouilh και Brecht και μας απασχόλησε το ιστορικό τους συγκείμενο.. Ένα άλλο θέμα που θίξαμε ήταν τι αντιπροσωπεύει η Αντιγόνη, ποια εξουσία ασκεί και υπερασπίζεται ο Κρέοντας;. Ασχοληθήκαμε επιπλέον με το ερώτημα τι είναι αυτό που κάνει την ηρωίδα να αντισταθεί μέχρι τέλους και να θυσιάσει τη ζωή της
description: The aim of the present thesis was the study of the confrontation between Creon and Antigone as a conflict between political authority and moral duty in Antigone as presented by Sophocles, Anouilh and Brecht. We examined the concepts of Myth and Intertextuality in an effort to associate them with Tragedy. Then we presented the concepts of political authority and moral duty. Furthermore, we analyzed the historical context of each dramatic play. We also examined what the young heroine represents and how royal authority is exercised by Creon. Another aim of this study was to explain why Antigone is willing to sacrifice her own life resisting royal authority
Teacher acceptance of the instructional environment scales (Ties)

Publisher: name: University of British Columbia

description: The Instructional Environment Scale (TIES), a measure designed to assist professionals in systematic analysis of a student's classroom environment, has not been readily accepted by classroom teachers. A review was conducted of the theory and the research upon which TIES was based and the research concerning factors influencing the acceptance of interventions by classroom teachers. From the latter research, it was hypothesized here that improved knowledge about TIES would enhance acceptance on the part of classroom teachers. Two experiments were conducted. In both experiments, subjects were presented with one of two descriptions of TIES. One of these was described as the low information condition, while the other was designated the high information condition. In the first experiment, the information was presented on videotape while in the second a lecture format was used. Information gained from the presentation was measured by a 20 item test of knowledge of TIES devised for the study. Acceptance of TIES was evaluated using a measure adapted from the Behaviour Intervention Rating Scale (BIRS: Von Brock and Elliott, 1987). Coefficients of reliability were found to be .64 and .65 for the knowledge measure and .91 for the acceptability measure. Subjects were student teachers and experienced teachers enrolled in summer session courses in educational psychology and special education. Demographic variables such as teaching experience, special education background, and level of students taught had no significant influence on the results. The null hypothesis that there would be no difference in acceptability ratings of TIES when teachers were given more information about the instrument could not be rejected in either experiment. Subject characteristics and methodological difficulties were discussed as limitations to the generalization of the results.

description: We present a novel method to investigate the dynamics of a single semiflexible polymer, subject to anisotropic friction in a viscous fluid. In contrast to previous approaches, we do not rely on a discrete bead-rod model, but introduce a suitable normal mode decomposition of a continuous space curve. By means of a perturbation expansion for stiff filaments we derive a closed set of coupled Langevin equations in mode space for the nonlinear dynamics in two dimensions, taking into account exactly the local constraint of inextensibility. The stochastic differential equations obtained this way are solved numerically, with parameters adjusted to describe the motion of actin filaments. As an example, we show results for the tumbling motion in shear flow.

description: Several counterexample models to the Nelson-Seiberg theorem have been discovered in previous literature, with generic superpotentials respecting the R-symmetry and non-generic R-charge assignments for chiral fields. This work present a sufficient condition for such counterexample models: The number of R-charge 2 fields, which is greater than the number of R-charge 0 fields, must be less than or equal to the number of R-charge 0 fields plus the number of independent field pairs with opposite R-charges and satisfying some extra requirements. We give a correct count of such field pairs when there are multiple field pairs with degenerated R-charges. These models give supersymmetric vacua with spontaneous R-symmetry breaking, thus are counterexamples to both the Nelson-Seiberg theorem and its extensions.

Phosphous limited community dynamics of steam benthic algae and insects
Creators: name: Quamme, D. L.
Publisher: name: University of British Columbia
Year: 2009

description: The relationship between external soluble phosphorus (P) concentration and the abundance and taxonomic composition of stream insects was determined in streamside artificial troughs. The response of peak algal biomass (PB) to target P concentrations of 0, 0.5, 2.5, 5, 10, 50 ɥg P 1⁻¹ was also monitored. A log-linear function of P concentration was used to approximate PB and insect abundance. PB measured as chlorophyll a increased with P concentration linearly to 7.4 mg m⁻² at 2.5 ɥg P 11 and reached an asymptote at 9.2 mg m⁻² (2.7X the controls). Adult baetid mayflies showed a significant increase in number after 23 days of P addition; this effect was maintained over 9 weeks of treatment. Numbers of benthic baetids, nemourid and perlodid stoneflies and hydroptilid tricopterans sampled at the end of the experiment significantly increased with P concentration. Adult and benthic insects of these taxa exhibited similar rapid increases in abundance from 0 - 2.5 ɥg P 1⁻¹ and all showed signs of saturation at approximately 1.5 - 3 times the controls at concentrations greater than 2.5 P l1. Increased abundances of insects resulted from greater food availability. There was no detectable difference in the numbers of large Baetid nymphs drifting from the troughs with increasing P concentration. Increased survival of Baetidae nymphs with increasing P level was thought to account for higher numbers of adult and benthic baetids observed with increasing P concentration. Graphical comparisons between the control and treated troughs showed that they were similar in taxonomic composition of insects. Insect taxonomic richness did not change with increasing P concentration. These findings are important to fisheries researchers who are assessing the potential of stream fertilization as a technique to enhance salmonid populations in nutrient deficient streams.

description: Constrained electronic-structure theories enable the construction of effective low-energy models consisting of partially dressed particles. However, the interpretation and physical content of these theories is not straightforward. Here, we carefully explore the properties of downfolding theories for electron-ion problems, in particular constrained density-functional perturbation theory (cDFPT). We show that the dipole selection rules determine whether the partially dressed phonons satisfy Goldstone's theorem, and we prove that electronic screening always lowers the phonon frequencies. We illustrate the theory with cDFPT calculations for minimal example systems: the nitrogen and benzene molecule as well as graphene.

description: Food is one of the most important economic sectors for the Greek economy. Honey is the most important product of beekeeping, while its history, which dates back to ancient times, is well known. Greece has always been a country that practiced beekeeping. Today, with the development of international markets, a major export product with significant economic profits is honey.Beekeeping is a productive industry that has a significant impact on the country's economy. Data on the global honey market is presented and continues with the analysis of statistics and numbers for beekeeping in Greece. The production, distribution and price of beekeeping products characterizes the healthy course of a beekeeping exploitation and the good beekeeping entrepreneur.The aim of the survey is to record the economic situation of the country in the beekeeping sector, as well as the statistical analysis and comparison of the country with the countries in European Union as well as internationally. Consequently, the main factors of economy (yields, sizes, way of practicing beekeeping, type of transport) are studied and ideas for optimization of the sector are presented. The conclusions lead to an overall view of the specific issue. Finally, there is an analysis of the balance sheets of five Greek beekeeping industries where results are presented and compared

description: Purpose: The study aimed to test a combination of semantic memory and traditional episodic memory therapies on episodic memory deficits in adults with traumatic brain injury.Method: Twenty-five participants who had been diagnosed with traumatic brain injury and had episodic memory deficits were randomly assigned either to a combined memory treatment group (n = 16) or to a wait-list control group (n = 9). Before and after treatment, they completed standardized neuropsychological testing for episodic memory and related cognitive domains, including the California Verbal Learning Test–Second Edition, the Controlled Oral Word Association Test, the University of Southern California Repeatable Episodic Memory Test, the Wechsler Abbreviated Scale of Intelligence–Second Edition Matrices, the Test of Everyday Attention, the Memory Assessment Clinics Self-Rating Scale, the Expressive Vocabulary Test–Second Edition, and the Story Recall subtest from the Rivermead Behavioural Memory Test. In addition to a traditional episodic memory therapy, the treatment group received a novel semantic memory–focused therapy, which involved participants finding meaningful connections between diverse concepts represented by sets of two or three words.Results: The treatment group demonstrated statistically significant improvement in memory for list learning tasks, and there was a significant difference from pretest to posttest between the treatment group and the wait-list control group. Clinical significance was demonstrated for the treatment group using minimally important difference calculations.Conclusion: Combined memory therapy resulted in significant improvements in episodic memory, semantic memory, and attention, in comparison to no treatment.

description: We analyze a novel approach to gauging rigid higher derivative (higher spin) symmetries of free relativistic actions defined on flat spacetime, building on the formalism originally developed by Bonora et al. and Bekaert et al. in their studies of linear coupling of matter fields to an infinite tower of higher spin fields. The off-shell definition is based on fields defined on a $2d$-dimensional master space equipped with a symplectic structure, where the infinite dimensional Lie algebra of gauge transformations is given by the Moyal commutator. Using this algebra we construct well-defined weakly non-local actions, both in the gauge and the matter sector, by mimicking the Yang-Mills procedure. The theory allows for a description in terms of an infinite tower of higher spin spacetime fields only on-shell. Interestingly, Euclidean theory allows for such a description also off-shell. Owing to its formal similarity to non-commutative field theories, the formalism allows for the introduction of a covariant potential which plays the role of the generalised vielbein. This covariant formulation uncovers the existence of other phases and shows that the theory can be written in a matrix model form. The symmetries of the theory are analyzed and conserved currents are explicitly constructed. By studying the spin-2 sector we show that the emergent geometry is closely related to teleparallel geometry, in the sense that the induced linear connection is opposite to Weitzenböck's.

description: We have calculated the explicit form of the real and imaginary parts of the effective potential for uniform magnetic fields which interact with spin-1/2 fermions through the Pauli interaction. It is found that the non-vanishing imaginary part develops for a magnetic field stronger than a critical field, whose strength is the ratio of the fermion mass to its magnetic moment. This implies the instability of the uniform magnetic field beyond the critical field strength to produce fermion pairs with the production rate density $w(x)=\frac{m^{4}}{24π}(\frac{|μB|}{m}-1)^{3}(\frac{|μB|}{m}+3)$ in the presence of Pauli interaction.

description: Η αμέλεια αποτελεί μία νομική έννοια που έχει εγείρει πληθώρα θεωρητικών και νομολογιακών συγκρούσεων. Σύμφωνα με την άποψη που επικρατεί στην ελληνική ποινική επιστήμη, η αμέλεια, πέραν από την παραδοσιακή της όψη ως στοιχείο υπαιτιότητας (εσωτερική αμέλεια), αποτελεί παράλληλα και στοιχείο του αδίκου (εξωτερική αμέλεια) υπό την ερμηνεία της εξωτερικά λανθασμένης συμπεριφοράς. Σκοπός της παρούσας διπλωματικής είναι η μελέτη της λεγόμενης εξωτερικής αμέλειας ως στοιχείο του αδίκου. Αρχικά, η παρούσα διπλωματική προσεγγίζει την προβληματική επιχειρώντας μια λεπτομερή παρουσίαση των διαφορετικών απόψεων των νομικών επιστημόνων επί του θέματος στα πλαίσια του Ελληνικού ποινικού δικαίου. Περαιτέρω, γίνεται αναφορά και στην ελληνική νομολογία, ώστε να αποκτά κανείς μια συνολική εικόνα για τη σημασία της ως άνω θεμελιώδους διάκρισης. Παράλληλα, επιχειρείται μια συσχέτιση της έννοιας της εξωτερικής αμέλειας με αυτές της αιτιότητας και της παράλειψης, αφού σχετίζονται στενά με το περιεχόμενο της παρούσας διπλωματικής.
description: Negligence is a concept of law that has raised a variety of theoretical and judicial conflicts. According to the dominant opinion in Greek criminal science, negligence, other than being conventionally viewed as an element of culpability (internal negligence), is also an element injustice (external negligence), under the interpretation of the externally incorrect behavior. The aim of the present thesis is the study of the so-called external negligence as an element of injustice. Firstly, the current thesis approaches the problem by attempting a detailed presentation of the different opinions of legal scholars on the matter in Greek criminal law. Furthermore, a reference is made to Greek jurisprudence, in order to obtain an overall view about the significance of the above mentioned fundamental distinction. At the same time, a connection between the concept of external negligence and those of causality and omission is attempted, since they are closely related to the content of this thesis.

description: Compton scattering of gamma rays propagating in a pair plasma can drive the formation of a relativistic electron positron beam. This process is scrutinised theoretically and numerically via particle-in-cell simulations. In addition, we determine in which conditions the beam can prompt a beam-plasma instability and convert its kinetic energy into magnetic energy. We argue that such conditions can be met at the photosphere radius of bright Gamma Ray Bursts.

As a main tool we use the theory of $n$-blocks and Beilinson's type spectral sequences. Cohomological characterizations of vector bundles are also showed.

description: We prove that there are tripartite quantum states (constructed from random unitaries) that can lead to arbitrarily large violations of Bell inequalities for dichotomic observables. As a consequence these states can withstand an arbitrary amount of white noise before they admit a description within a local hidden variable model. This is in sharp contrast with the bipartite case, where all violations are bounded by Grothendieck's constant. We will discuss the possibility of determining the Hilbert space dimension from the obtained violation and comment on implications for communication complexity theory. Moreover, we show that the violation obtained from generalized GHZ states is always bounded so that, in contrast to many other contexts, GHZ states do in this case not lead to extremal quantum correlations. The results are based on tools from the theories of operator spaces and tensor norms which we exploit to prove the existence of bounded but not completely bounded trilinear forms from commutative C*-algebras.

description: Purpose: Moderate-to-severe traumatic brain injury (TBI) leads to significant neural and cognitive impairment, affecting functional outcome. This study investigated the chronic effects of moderate-to-severe TBI on brain reserve (BR), cognitive reserve (CR), and neuropsychological and functional outcome.Method: The group with TBI consisted of 41 male participants with a primary diagnosis of moderate-to-severe closed head injury (time since injury [TSI], M = 6.12 years, range: 1–23, SD = 5.99, Mdn = 4). TBI survivors were compared to 24 neurotypical male participants, matched on age and education. Magnetic resonance imaging T1 anatomical images were used to calculate gray and white matter and cerebrospinal fluid volume. BR was calculated using the ventricle-to-brain ratio. CR was assessed using two hold measures: the Peabody Picture Vocabulary Test and the Pseudowords task. Functional outcome was measured using the Glasgow Outcome Scale–Extended.Results: Neuropsychological performance of TBI survivors was significantly lower than their neurotypical controls, as measured by theoretically driven composites of verbal and visual memory, executive functions, attention, and CR. They presented greater ventricle-to-brain ratio volume, compared to noninjured controls, with higher scores indicating lower BR levels. Both BR and TSI were significantly associated with CR. Also, a median-split analysis revealed a TSI effect on CR. Significant associations were evident between the Glasgow Outcome Scale–Extended and the BR and CR measures.Conclusions: Lingering neuropsychological deficits in chronic TBI support the role of BR and CR in functional outcome. Furthermore, TSI interferes with CR supporting the notion that TBI sets off a chronic neurodegenerative and progressive course that interferes with semantic knowledge.

description: The gap generation in the dice model with local four-fermion interaction is studied. Due to the presence of two valleys with degenerate electron states, there are two main types of gaps. The intra- and intervalley gap describes the electron and hole pairing in the same and different valleys, respectively. We found that while the generation of the intravalley gap takes place only in the supercritical regime, the intervalley gap is generated for an arbitrary small coupling. The physical reason for the absence of the critical coupling is the catalysis of the intervalley gap generation by the flat band in the electron spectrum of the dice model. The completely quenched kinetic energy in the flat band when integrated over momentum in the gap equation leads to extremely large intervalley gap proportional to the area of the Brillouin zone.

description: Light bosonic scalars (e.g. axions) may form clouds around black holes via superradiant instabilities, or via accretion if they form some component of the dark matter. It has been suggested that their presence may lead to a distinctive dephasing of the gravitational wave signal when a small compact object spirals into a larger black hole. Motivated by this, we study numerically the dynamical friction force on a black hole moving at relativistic velocities in a background scalar field with an asymptotically homogeneous energy density. We show that the relativistic scaling is analogous to that found for supersonic collisional fluids, assuming an approximate expression for the pressure correction which depends on the velocity and scalar mass. While we focus on a complex scalar field, our results confirm the expectation that real scalars would exert a force which oscillates between positive and negative values in time with a frequency set by the scalar mass. The complex field describes the time averaged value of this force, but in a real scalar the rapid force oscillations could in principle leave an imprint on the trajectory. The approximation we obtain can be used to inform estimates of dephasing in the final stages of an extreme mass ratio inspiral.

description: Σκοπός της διατριβής ήταν η μελέτη της αφήγησης του Ιησού με τη Σαμαρείτιδα (Ιω.4,5-42) και η εξήγηση και η ιστορία της πρόσληψής της στην αρχαία Εκκλησία. Στο πρώτο κεφάλαιο εξετάσαμε την ιστορία της περικοπής της Σαμαρείτιδας, τη θέση που κατέχει μέσα στο κατά Ιωάννην Ευαγγέλιο, τη δομή της και τη Θεολογία της, αλλά και την ερμηνεία που έχουν δώσει κατά καιρούς διάφοροι μελετητές που στάθηκαν σε κάποια σημαντικά σημεία. Στο δεύτερο κεφάλαιο εξετάσαμε τις Πατερικές ερμηνείες και τάσεις όσον αφορά τη συγκεκριμένη περικοπή , αλλά και τη σημασία αυτών. Τέλος παραθέσαμε τα συμπεράσματά μας
description: The aim of the present thesis was the study of the story of Jesus with the Samaritan woman (John.4. 5-42) and the explanation and history of her recruitment to the ancient Church. In the first chapter, we examined the history of the Samaritans' excerpt, the position it occupies in the Gospel of John, its structure and its theology, and the interpretation given by various scholars who have stood at some important points. In the second chapter, we examined the Patristic interpretations and tendencies in this cut, but also the significance of these. Finally, we quoted our conclusions
Examination of the British Columbia Community Tourism Action Program

Publisher: name: University of British Columbia

description: This thesis examines and evaluates the British Columbia Community Tourism Action Program (CTAP), a provincial program that aims to help communities broaden their economic bases by developing tourism. Specifically, it questions how isolated single-industry towns implement the British Columbia CTAP, and how they evaluate it, using the examples of Golden and Ucluelet, both of which have been using the program since 1991. The thesis does not base its conclusions on financial data, but on the communities' responses to a questionnaire about the CTAP, on meetings with each community's tourism action committee, and on a comparison of theories of tourism planning with the actual workings of the British Columbia CTAP. After establishing why single-industry towns may have a special need to diversify their economies, the thesis traces the evolution of the British Columbia CTAP from two other programs: its predecessor—British Columbia Tourism Development Strategy— and the Alberta Community Tourism Action Program. Following this history is a brief description of why tourism planning is necessary, including some of the environmental, economic and social effects of tourism, and then a review of the literature concerning tourism planning. A detailed study of the Golden and Ucluelet plans, several evaluations of the program, and recommendations for future research complete the thesis. Since the town representatives responses to the British Columbia CTAP have been favourable and since the program matches several of the most important theoretical requirements of tourism planning, the thesis concludes with qualified approval of the program. Reservations about the program's effectiveness include concerns about how well all the residents of a town are represented, how the program is evaluated, and how the program deals with sustainability issues. The final recommendations section sketches in how these problems might be addressed and also suggests some supplements to the CTAP.

description: Modelling the end point of binary black hole mergers is a cornerstone of modern gravitational-wave astronomy. Extracting multiple quasinormal mode frequencies from the ringdown signal allows the remnant black hole to be studied in unprecedented detail. Previous studies on numerical relativity simulations of aligned-spin binaries have found that it is possible to start the ringdown analysis much earlier than previously thought if overtones (and possibly mirror modes) are included. This increases the signal-to-noise ratio in the ringdown making identification of subdominant modes easier. In this paper we study, for the first time, black hole binaries with misaligned spins and find a much greater variation in the performance of ringdown fits than in the aligned-spin case. The inclusion of mirror modes and higher harmonics, along with overtones, improves the reliability of ringdown fits with an early start time; however, there remain cases with poor performing fits. While using overtones in conjunction with an early ringdown start time is an enticing possibility, it is necessary to proceed with caution. We also consider for the first time the use of numerical relativity surrogate models in this type of quasinormal mode study and address important questions of accuracy in the underlying numerical waveforms used for the fit.

Black Hole Thermodynamics from Euclidean Horizon Constraints

description: To explain black hole thermodynamics in quantum gravity, one must introduce constraints to ensure that a black hole is actually present. I show that for a large class of black holes, such ``horizon constraints'' allow the use of conformal field theory techniques to compute the density of states, reproducing the Bekenstein-Hawking entropy in a nearly model-independent manner. One standard string theory approach to black hole entropy arises as a special case, lending support to the claim that the mechanism may be ``universal.'' I argue that the relevant degrees of freedom are Goldstone-boson-like excitations arising from the weak breaking of symmetry by the constraints.

description: Σκοπός της παρούσας έρευνας είναι να παρουσιάσει τις αναγνωστικές δυσκολίες που αντιμετωπίζουν οι μαθητές με δυσλεξία στο Γυμνάσιο και, στη συνέχεια, να σχεδιαστεί η κατάλληλη παρέμβαση που θα συμβάλει στη βελτίωση της αποκωδικοποίησης και της ευχερούς ανάγνωσης. Η μεθοδολογία που χρησιμοποιήθηκε ήταν η έρευνα δράσης. Ως προς τον αριθμό των συμμετεχόντων πραγματοποιήθηκε μία μελέτη περίπτωσης. Ως παράδειγμα για τη μελέτη επιλέχθηκε μία μαθήτρια της Β΄ Γυμνασίου με δυσλεξία. Η έρευνα ξεκίνησε με το στάδιο της διάγνωσης. Σε αυτό το στάδιο συγκεντρώθηκαν όλες οι απαραίτητες πληροφορίες που χρειάστηκαν για το σχεδιασμό της κατάλληλης παρέμβασης. Ακολούθησε το στάδιο της παρέμβασης που βασίστηκε στη μέθοδο «Αναγνωστική Επιτυχία» και πραγματοποιήθηκε σε δύο φάσεις με μία ενδιάμεση αξιολόγηση. Με την ολοκλήρωση της παρέμβασης διεξήχθη η τελική αξιολόγηση. Τα αποτελέσματα των μετρήσεων έδειξαν πως η μαθήτρια παρουσίασε μία μικρή βελτίωση στις δοκιμασίες που αφορούσαν την αποκωδικοποίηση των λέξεων και την αναγνωστική ευχέρεια. Συνεπώς, με την εφαρμογή ενός εξατομικευμένου προγράμματος παρέμβασης είναι δυνατή η ενίσχυση της αναγνωστικής ικανότητας των μαθητών με δυσλεξία στο Γυμνάσιο
description: The purpose of this study is to present reading difficulties faced by students with dyslexia and then to design an effective intervention program that will help them to improve decoding and reading fluency. In order to investigate the process action research was used. In this paper a case study of a Second - Grade Gymnasium student with dyslexia was evaluated. The first stage of the research was the diagnostic stage. At this stage, all the important information needed to design the educational intervention was selected. The interventions were based on the program "Reading Success" and carried out in two phases with an interim evaluation. Upon completion of the intervention, the final assessment was carried out. The results of the measurements showed that the student performed a slight improvement in the tests related to word decoding and reading ability. Therefore, with the implementation of an individualized intervention program, it is possible to enhance the reading ability of students with dyslexia in the Gymnasium

description: We make use of recent developments in the analysis of galaxy redshift surveys to present an easy to use matrix-based analysis framework for the galaxy power spectrum multipoles, including wide-angle effects and the survey window function. We employ this framework to derive the deconvolved power spectrum multipoles of 6dFGS DR3, BOSS DR12 and the eBOSS DR16 quasar sample. As an alternative to the standard analysis, the deconvolved power spectrum multipoles can be used to perform a data analysis agnostic of survey specific aspects, like the window function. We show that in the case of the BOSS dataset, the Baryon Acoustic Oscillation (BAO) analysis using the deconvolved power spectra results in the same likelihood as the standard analysis. To facilitate the analysis based on both the convolved and deconvolved power spectrum measurements, we provide the window function matrices, wide-angle matrices, covariance matrices and the power spectrum multipole measurements for the datasets mentioned above. Together with this paper we publish a \code{Python}-based toolbox to calculate the different analysis components. The appendix contains a detailed user guide with examples for how a cosmological analysis of these datasets could be implemented. We hope that our work makes the analysis of galaxy survey datasets more accessible to the wider cosmology community.
