description: Η συγκεκριμένη διπλωματική εργασία θίγει το ζήτημα των προδικαστικών ζητημάτων και το κατά πόσο αυτά δύνανται να δεσμεύσουν τη δικάζουσα σύνθεση στην διαμόρφωση της τελικής δικανικής πεποίθησης, εν μέσω ενός αποδεικτικού συστήματος, σαν του ελληνικού,που έχει ως βασική αρχή , την αρχή της ηθικής απόδειξης, ήτοι τη μη δέσμευση του δικαστηρίου από αποδεικτικούς κανόνες, καθώς και το απεριόριστο των αποδεικτικών μέσων. Επιπρόσθετα, με την προσεκτική επισκόπηση της νομολογίας του Ευρωπαϊκού Δικαστηρίου γίνεται εκτενέστατη παράθεση της συμβατότητας τυχόν τεκμηρίων ενοχής που υπάρχουν στις έννομες τάξεις των κρατών μελών, με το άρθρο 6 παρ. 1 και 2 της Ευρωπαϊκής Σύμβασης των Δικαιωμάτων του Ανθρώπου, δηλαδή με τις έννοιες της δίκαιης δίκης και του τεκμηρίου αθωότητας. Σχετικά με την εγχώρια έννομη τάξη, παρουσιάζονται όλες οι νομοθετικές μεταβολές που επήλθαν με το Ν. 4596/2019, κατ’ εφαρμογή της Οδηγίας του Συμβουλίου της Ευρώπης 343/2016, καθώς και με το Ν. 4619/2020 που οδήγησε το σύνολο του ελληνικού Ποινικού Κώδικα σε θορυβώδεις αλλαγές. Επιπλέον, θίγεται και η προβληματική που έχει δημιουργηθεί σε περιπτώσεις που μία υπόθεση κρίνεται και από την ποινική της σκοπιά αλλά και από την αστική της. Υπάρχει αναγκαιότητα χάριν ασφάλειας δικαίου να συμπλέουν τα σκεπτικά των αποφάσεων ή μπορούν αυτά να αχθούν σε πλήρως αντιφατικές δικανικές κρίσεις
description: Τhe hereby dissertation is about the preliminary issues and their binding effect at the formulation of the final verdict in a criminal court. Τhis matters a lot, especially in a criminal legal system like the Greek one, where the judge is not obliged to follow certain rules referred to the bindict effect of the means of proof in a trial. In addition to this, there is a detailed presentation of the European Court case – law, and also the issue of the compatibility οf existing in the European countries legal systems presumptions of guilt, with the art. 6 par. 1 and 2 of the ECHR, in other words with the right in a fair trial and with the presumption of innocence. According to the Greek legal system, there have been some amendments due to the Law 4596/2019, which integrated the Direction of the European Council 343/2016, and also due to the Law 4619/2020, which changed completely the Greek Criminal Law. Also, it is referred to the important issue of the situations that one case has and a criminal status, but also a civil status. Is there a need of protecting the legal certainty due to the resemblance of the verdicts of different courts or can the verdicts be completely different with each other?

description: A simplicial complex is a generalization of a graph: a collection of n-ary relationships (instead of binary as the edges of a graph), named simplices. In this paper, we develop a new tool to study the structure of simplicial complexes: we generalize the graph notion of truss decomposition to complexes, and show that this more powerful representation gives rise to different properties compared to the graph-based one. This power, however, comes with important computational challenges derived from the combinatorial explosion caused by the downward closure property of complexes. Drawing upon ideas from itemset mining and similarity search, we design a memory-aware algorithm, dubbed STruD, which is able to efficiently compute the truss decomposition of a simplicial complex. STruD adapts its behavior to the amount of available memory by storing intermediate data in a compact way. We then devise a variant that computes directly the n simplices of maximum trussness. By applying STruD to several datasets, we prove its scalability, and provide an analysis of their structure. Finally, we show that the truss decomposition can be seen as a filtration, and as such it can be used to study the persistent homology of a dataset, a method for computing topological features at different spatial resolutions, prominent in Topological Data Analysis.
Historical Sunspot Observations: A Review

description: Early observations of sunspot were realised by the naked eye. Possible utilization of these records for studying the long-term change in the Sun is discussed here. Other historical sunspot observations with camera obscuras are also discussed. Moreover, the best record of the behaviour of the Sun exists for the last four centuries thanks to the observations of sunspots with telescope. These observations should allow us to know the number, position, and area of sunspots as well as some relevant episodes (Maunder Minimum, optical flares, etc.). Rudolf Wolf developed the first reconstruction of solar activity in the 19th century. The next reconstruction was made by Hoyt and Schatten in 1998 by improving the database and using a new methodological approach. Here some mistakes, pending tasks and minor improvements are discussed.

Secondary school students and the information seeking process
Creators: name: Rowe, Marion Elizabeth Anne Mosley
Publisher: name: University of British Columbia
Year: 2008

description: The purpose of this study was to discover what perceptions secondary school students held of the information seeking process and what behaviours the students used to initiate and carry out an information search. The study was conducted in a secondary school in North Central British Columbia, with students from Two Grade 8 and two Grade 10 Humanities classes. Data was collected by means of student journal writings, recorded interviews with randomly selected students and by participant observation. The study revealed that students held five principal perceptions about information seeking: that it provided active involvement for them in their own education; that it was a positive experience; that it made them aware of the importance of practising self discipline; that it taught them skills they needed to locate and select information as well as analyze, record and classify information; and that an information search involved varying degrees of student frustration. The study further revealed that student behaviours during a search for information were grouped into three areas: initiating behaviours; recording, analyzing and classifying behaviours; and organizational behaviours. Two further findings were stated: the importance of previous student practice with cooperatively planned projects; as well as the significance of locating computer facilities visibly adjacent to the School Library Resource Centre in elementary and secondary schools.

description: A set of unified relativistic mean-field equations of state for hyperonic compact stars recently built in [M. Fortin, Ad. R. Raduta, S. Avancini, and C. Providencia, Phys. Rev. D {\bf 101}, 034017 (2020)] is used to study the thermal evolution of non-magnetized and non-rotating spherically-symmetric isolated and accreting neutron stars under different hypothesis concerning proton $S$-wave superfluidity. These equations of state have been obtained in the following way: the slope of the symmetry energy is in agreement with experimental data; the coupling constants of $Λ$ and $Ξ$-hyperons are determined from experimental hypernuclear data; uncertainties in the nucleon-$Σ$ interaction potential are accounted for; current constraints on the lower bound of the maximum neutron star mass are satisfied. Within the considered set of equations of state, the presence of hyperons is essential for the description of the cooling/heating curves. One of the conclusions we reach is that the criterion of best agreement with observational data leads to different equations of states and proton $S$-wave superfluidity gaps when applied separately for isolated neutron stars and accreting neutron stars in quiescence. This means that at least in one situation the traditional simulation framework that we employ is not complete and/or the equations of state are inappropriate. Another result is that, considering equations of state which do not allow for nucleonic dUrca or allow for it only in very massive NS, the low luminosity of SAX J1808 requires a repulsive $Σ$-hyperon potential in symmetric nuclear matter in the range $U_Σ^{(N)}\approx 10-30$ MeV. This range of values for $U_Σ^{(N)} $ is also supported by the criterion of best agreement with all available data from INS and XRT.

description: In this letter we study the generation of gravitational waves during inflation from a 5D vacuum theory of gravity. Within this formalism, on an effective 4D de Sitter background, we recover the typical results obtained with 4D inflationary theory in general relativity, for the amplitude of gravitational waves generated during inflation. We also obtain a range of values for the amplitude of tensor to scalar ratio which is in agreement with COBE observations.

description: We identify label errors in the test sets of 10 of the most commonly-used computer vision, natural language, and audio datasets, and subsequently study the potential for these label errors to affect benchmark results. Errors in test sets are numerous and widespread: we estimate an average of at least 3.3% errors across the 10 datasets, where for example label errors comprise at least 6% of the ImageNet validation set. Putative label errors are identified using confident learning algorithms and then human-validated via crowdsourcing (51% of the algorithmically-flagged candidates are indeed erroneously labeled, on average across the datasets). Traditionally, machine learning practitioners choose which model to deploy based on test accuracy - our findings advise caution here, proposing that judging models over correctly labeled test sets may be more useful, especially for noisy real-world datasets. Surprisingly, we find that lower capacity models may be practically more useful than higher capacity models in real-world datasets with high proportions of erroneously labeled data. For example, on ImageNet with corrected labels: ResNet-18 outperforms ResNet-50 if the prevalence of originally mislabeled test examples increases by just 6%. On CIFAR-10 with corrected labels: VGG-11 outperforms VGG-19 if the prevalence of originally mislabeled test examples increases by just 5%. Test set errors across the 10 datasets can be viewed at https://labelerrors.com and all label errors can be reproduced by https://github.com/cleanlab/label-errors.

description: Disease prediction is a well-known classification problem in medical applications. GCNs provide a powerful tool for analyzing the patients' features relative to each other. This can be achieved by modeling the problem as a graph node classification task, where each node is a patient. Due to the nature of such medical datasets, class imbalance is a prevalent issue in the field of disease prediction, where the distribution of classes is skewed. When the class imbalance is present in the data, the existing graph-based classifiers tend to be biased towards the major class(es) and neglect the samples in the minor class(es). On the other hand, the correct diagnosis of the rare positive cases among all the patients is vital in a healthcare system. In conventional methods, such imbalance is tackled by assigning appropriate weights to classes in the loss function which is still dependent on the relative values of weights, sensitive to outliers, and in some cases biased towards the minor class(es). In this paper, we propose a Re-weighted Adversarial Graph Convolutional Network (RA-GCN) to prevent the graph-based classifier from emphasizing the samples of any particular class. This is accomplished by associating a graph-based neural network to each class, which is responsible for weighting the class samples and changing the importance of each sample for the classifier. Therefore, the classifier adjusts itself and determines the boundary between classes with more attention to the important samples. The parameters of the classifier and weighting networks are trained by an adversarial approach. We show experiments on synthetic and three publicly available medical datasets. RA-GCN demonstrates the superiority compared to recent methods in identifying the patient's status on all three datasets. The detailed analysis is provided as quantitative and qualitative experiments on synthetic datasets.
The integrated Sachs-Wolfe effect in cosmologies with coupled dark matter and dark energy

Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: The subject of this paper is the derivation of the integrated Sachs-Wolfe (iSW) effect in cosmologies with coupled dark matter and dark energy fluids. These couplings influence the iSW-effect in three ways: The Hubble function assumes a different scaling, the structure growth rate shows a different time evolution, and in addition, the Poisson equation, which relates the density perturbations to fluctuations in the gravitational potential, is changed, due to the violation of the scaling rho ~ a^{-3} of the matter density rho with scale factor a. Exemplarily, I derive the iSW-spectra for a model in which dark matter decays into dark energy, investigate the influence of the dark matter decay rate and the dark energy equation of state on the iSW-signal, and discuss the analogies for gravitational lensing. Quite generally iSW-measurements should reach similar accuracy in determining the dark energy equation of state parameter and the coupling constant.

Direct and indirect placement test scores as measures of language proficiency and predictors of academic success for ESL students
Creators: name: Christopher, Virginia Louise
Publisher: name: University of British Columbia
Year: 2009

description: Much valuable research in the area of English as a second language has focused on testing, and though many studies have investigated issues related to test reliability, validity and the predictive ability of indirect test scores, they do not assess the comparative ability of indirect and direct test scores to predict academic success. Work of this kind would inform practice in the area of testing and placement. This study investigates the practical problem of making appropriate placement decisions for students whose test results show wide enough discrepancies to indicate placement in different academic programs, or at different levels within programs. The question of whether scores derived from indirect measures (language proficiency tests) or direct measures (writing samples) are better indicators of academic language proficiency is addressed. The study also explores the usefulness of grade point average (GPA) as a measure of academic success, and proposes the use of average accumulated credit per semester (AACPS) as an additional measure. Several researchers have questioned the use of GPA as the sole measure of academic success for ESL students, and this study adds to existing research. The ability of two types of placement test scores to predict academic success for ESL students in Secondary and University programs is evaluated. Test scores from a) an indirect measure of language proficiency, the Michigan Test of English Language Proficiency, and b) a direct measure, a holistically-scored writing test are assessed as predictors of four measures of academic success: a) GPA for all courses, b) GPA for courses requiring a higher level of language proficiency (English or Humanities), c) GPA for courses requiring a lower level of language proficiency (Math or Sciences), and d) AACPS. Results of correlation analysis indicated that for University students, academic success as measured by GPA showed low correlations to both indirect or direct test scores, but direct test scores and combined (indirect and direct) test scores correlated moderately well to academic success as measured by AACPS. For Secondary students, academic success as measured by GPA for courses requiring a higher level of language proficiency (English or Humanities) showed moderate correlations to direct test scores. Correlations between test scores and any other measure of academic success including AACPS were low for Secondary students.

description: Coronal Mass Ejections (CMEs) are large-scale eruptions from the Sun into interplanetary space. Despite being major space weather drivers, our knowledge of the CME properties in the inner heliosphere remains constrained by the scarcity of observations at distances other than 1 au. Furthermore, most CMEs are observed in situ by single spacecraft, requiring numerical models to complement the sparse observations available. We aim to assess the ability of the linear force-free spheromak CME model in EUHFORIA to describe the radial evolution of interplanetary CMEs, yielding new context for observational studies. We model one well-studied CME, and investigate its radial evolution by placing virtual spacecraft along the Sun-Earth line in the simulation domain. To directly compare observational and modelling results, we characterise the interplanetary CME signatures between 0.2 and 1.9 au from modelled time series, exploiting techniques traditionally employed to analyse real in situ data. Results show that the modelled radial evolution of the mean solar wind and CME values is consistent with observational and theoretical expectations. The CME expands as a consequence of the decaying pressure in the surrounding wind: the expansion is rapid within 0.4 au, and moderate at larger distances. The early rapid expansion could not explain the overestimated CME radial size in our simulation, suggesting this is an intrinsic limitation of the spheromak geometry used. The magnetic field profile indicates a relaxation of the CME during propagation, while ageing is most probably not a substantial source of magnetic asymmetry beyond 0.4 au. We also report a CME wake that is significantly shorter than suggested by observations. Overall, EUHFORIA provides a consistent description of the radial evolution of solar wind and CMEs; nevertheless, improvements are required to better reproduce the CME radial extension.

Για το σκοπό αυτό αναλύθηκαν με τη χρήση της θεματικής ανάλυσης αποσπάσματα από ομάδες εστίασης που πραγματοποιήθηκαν στα πλαίσια του προγράμματος S.U.C.R.E. (Supporting University Community pathways for REfugees-migrants). Μέσα από αυτή τη διαδικασία προέκυψαν τέσσερις κύριοι θεματικοί άξονες. Ο πρώτος αφορά την χωροχρονική υπόσταση της προσωρινότητας, μέσω της μετακίνησης πληθυσμών σε διαφορετικές τοποθεσίες στο φάσμα του χρόνου. Ο δεύτερος άξονας σχετίζεται με τη δραστηριοποίηση των προσφύγων μέσα στο καθεστώς της παρατεταμένης προσωρινότητας. Ο τρίτος αφορά την προσωρινότητα του εργασιακού πλαισίου των επαγγελματιών υγείας που απασχολούνται στο χώρο του προσφυγικού. Ο τέταρτος άξονας αφορά τις ευρύτερες πολιτικές (των μη κυβερνητικών οργανώσεων, του κράτους και της Ευρωπαϊκής Ένωσης) που σχετίζονται με την προσφυγική κρίση και το καθεστώς της προσωρινότητας. Τα αποτελέσματα της μελέτης συζητήθηκαν αναφορικά με τις επιπτώσεις του προσωρινού στην αυτενέργεια και την ευημερία των πληθυσμών, τις δυσκολίες των εργαζομένων στο διαρκώς μεταβαλλόμενο εργασιακό περιβάλλον, καθώς και με τις κοινωνικές, πολιτικές και οικονομικές προεκτάσεις της δημιουργίας ενός πλαισίου ρευστότητας στο ζήτημα του προσφυγικού, τόσο στην ελληνική επικράτεια αλλά και σε ένα ευρύτερο επίπεδο.
description: The current research focuses on the temporality in the context of the refugee crisis in Greece, as it is constructed in the discourse of the employees that are being occupied with refugees. Focus groups discussions conducted for the S.U.C.R.E. program (Supporting University Community pathways for REfugees-migrants) were analyzed using thematic analysis and four basic topics emerged. The first one concerns the space-time aspect of temporality, through the mobility of the refugees in different spaces through the spectrum of time.The second subject concerns the agency of refugees when temporarily protracted, while the third one discusses the temporality in terms of employment of the professionals occupied in refugee shelters. As far as the fourth topic, it refers to the broader policies (of the non- governmental organizations, of the state and of the European Union) that concern the refugee crisis and the status of temporality. The results of this paper have been discussed regarding the consequences of the temporality to the agency and the well being of the refugee populations, the difficulties of the employees in a continuously varying working environment, as well as the social, political and economical consequences of the creation of a temporal context in the refugee crisis in Greece and in a broader level.

description: Medical data sets are usually corrupted by noise and missing data. These missing patterns are commonly assumed to be completely random, but in medical scenarios, the reality is that these patterns occur in bursts due to sensors that are off for some time or data collected in a misaligned uneven fashion, among other causes. This paper proposes to model medical data records with heterogeneous data types and bursty missing data using sequential variational autoencoders (VAEs). In particular, we propose a new methodology, the Shi-VAE, which extends the capabilities of VAEs to sequential streams of data with missing observations. We compare our model against state-of-the-art solutions in an intensive care unit database (ICU) and a dataset of passive human monitoring. Furthermore, we find that standard error metrics such as RMSE are not conclusive enough to assess temporal models and include in our analysis the cross-correlation between the ground truth and the imputed signal. We show that Shi-VAE achieves the best performance in terms of using both metrics, with lower computational complexity than the GP-VAE model, which is the state-of-the-art method for medical records.

description: Elastic geodesic grids (EGG) are lightweight structures that can be deployed to approximate designer-provided free-form surfaces. Initially, the grids are perfectly flat, during deployment, a curved shape emerges, as grid elements bend and twist. Their layout is based on networks of geodesic curves and is found geometrically. Encoded in the planar grids is the intrinsic shape of the design surface. Such structures may serve purposes like free-form sub-structures, panels, sun and rain protectors, pavilions, etc. However, so far the EGG have only been investigated using a generic set of design surfaces and small-scale desktop models. Some limitations become apparent when considering more sophisticated design surfaces, like from free-form architecture. Due to characteristics like high local curvature or non-geodesic boundaries, they may be captured only poorly by a single EGG. We show how decomposing such surfaces into smaller patches serves as an effective strategy to tackle these problems. We furthermore show that elastic geodesic grids are in fact well suited for this approach. Finally, we present a showcase model of some meters in size and discuss practical aspects concerning fabrication, size, and easy deployment.

description: We discuss the effects of non-linear structure formation on the signature of acoustic oscillations in the late-time galaxy distribution. We argue that the dominant non-linear effect is the differential motion of pairs of tracers separated by 150 Mpc. These motions are driven by bulk flows and cluster formation and are much smaller than the acoustic scale itself. We present a model for the non-linear evolution based on the distribution of pairwise Lagrangian displacements that provides a quantitative model for the degradation of the acoustic signature, even for biased tracers in redshift space. The Lagrangian displacement distribution can be calibrated with a significantly smaller set of simulations than would be needed to construct a precise power spectrum. By connecting the acoustic signature in the Fourier basis with that in the configuration basis, we show that the acoustic signature is more robust than the usual Fourier-space intuition would suggest because the beat frequency between the peaks and troughs of the acoustic oscillations is a very small wavenumber that is well inside the linear regime. We argue that any possible shift of the acoustic scale is related to infall on 150 Mpc scale, which is O(0.5%) fractionally at first-order even at z=0. For the matter, there is a first-order cancellation such that the mean shift is O(10^{-4}). However, galaxy bias can circumvent this cancellation and produce a sub-percent systematic bias.

description: The first phase-resolved JHK light curves of the eclipsing polar (AM Herculis binary) V1309 Ori are presented and interpreted. We separate the contributions from the secondary star and from other sources with the aim of determining a photometric distance. Simple model calculations show that the accretion stream and the cyclotron source on the accreting white dwarf are minor contributors to the infrared light, allowing an accurate determination of spectral type and absolute flux of the secondary star. The unilluminated backside of the secondary star as seen in eclipse has spectral type dM0 to dM0+. Its dereddened magnitude is K = 13.58 at orbital phase phi = 0 (eclipse). Using the calibrated surface brightness of M-stars and the published mass of the secondary, M2 = 0.46 Msun, we obtain a distance d = 600 +/- 25 pc which scales as M2^(1/2). The radius of the Roche-lobe filling secondary exceeds the main-sequence radius of an M0 star by 21 +11/-6 %. The debated origin of the infrared light of V1309 Ori has been settled in favor of the secondary star as the main contributor and an accurate distance has been derived that will place estimates of the luminosity and synchronization time scale on a more secure basis.

description: Virtual Assistant technology is rapidly proliferating to improve productivity in a variety of tasks. While several virtual assistants for everyday tasks are well-known (e.g., Siri, Cortana, Alexa), assistants for specialty tasks such as software engineering are rarer. One key reason software engineering assistants are rare is that very few experimental datasets are available and suitable for training the AI that is the bedrock of current virtual assistants. In this paper, we present a set of Wizard of Oz experiments that we designed to build a dataset for creating a virtual assistant. Our target is a hypothetical virtual assistant for helping programmers use APIs. In our experiments, we recruited 30 professional programmers to complete programming tasks using two APIs. The programmers interacted with a simulated virtual assistant for help - the programmers were not aware that the assistant was actually operated by human experts. We then annotated the dialogue acts in the corpus along four dimensions: illocutionary intent, API information type(s), backward-facing function, and traceability to specific API components. We observed a diverse range of interactions that will facilitate the development of dialogue strategies for virtual assistants for API usage.

description: Due to their ability to recognize complex patterns, neural networks can drive a paradigm shift in the analysis of materials science data. Here, we introduce ARISE, a crystal-structure identification method based on Bayesian deep learning. As a major step forward, ARISE is robust to structural noise and can treat more than 100 crystal structures, a number that can be extended on demand. While being trained on ideal structures only, ARISE correctly characterizes strongly perturbed single- and polycrystalline systems, from both synthetic and experimental resources. The probabilistic nature of the Bayesian-deep-learning model allows to obtain principled uncertainty estimates, which are found to be correlated with crystalline order of metallic nanoparticles in electron tomography experiments. Applying unsupervised learning to the internal neural-network representations reveals grain boundaries and (unapparent) structural regions sharing easily interpretable geometrical properties. This work enables the hitherto hindered analysis of noisy atomic structural data from computations or experiments.

description: The aim of the diplomatic work was to study the legal good of juveniles age, as protected by the provisions of the 19th chapter of the Penal Code. Through a historical flashback to the legislative, theoretical and legal approach to this issue, we have drawn conclusions about the degree and desirability of protecting this good, the constant changes that have taken place legislatively in terms of its protection, as well as its current size. We examined the terminology and basic concepts used in the offences under consideration which have troubled from time to time and continue to be a problem for theory and case-law and the effects of these problematic concepts in their interpretation of the protection of the legal good of juveniles age in the application of the provisions containing them concerning crimes of a sexual nature

description: A large set of recent experiments has been exploring topological transport in bosonic systems, e.g. of photons or phonons. In the vast majority, time-reversal symmetry is preserved, and band structures are engineered by a suitable choice of geometry, to produce topologically nontrivial bandgaps in the vicinity of high-symmetry points. However, this leaves open the possibility of large-quasimomentum backscattering, destroying the topological protection. Up to now, it has been unclear what precisely are the conditions where this effect can be sufficiently suppressed. In the present work, we introduce a comprehensive semiclassical theory of tunneling transitions in momentum space, describing backscattering for one of the most important system classes, based on the valley Hall effect. We predict that even for a smooth domain wall effective scattering centres develop at locations determined by both the local slope of the wall and the energy. Moreover, our theory provides a quantitative analysis of the exponential suppression of the overall reflection amplitude with increasing domain wall smoothness.

description: Giant micelles are elongated, polymer-like objects created by the self-assembly of amphiphilic molecules (such as detergents) in solution. Giant micelles are typically flexible, and can become highly entangled even at modest concentrations. The resulting viscoelastic solutions show fascinating flow behaviour (rheology) which we address theoretically in this article at two levels. First, we summarise advances in understanding linear viscoelastic spectra and steady-state nonlinear flows, based on microscopic constitutive models that combine the physics of polymer entanglement with the reversible kinetics of self-assembly. Such models were first introduced two decades ago, and since then have been shown to explain robustly several distinctive features of the rheology in the strongly entangled regime, including extreme shear-thinning. We then turn to more complex rheological phenomena, particularly involving spatial heterogeneity, spontaneous oscillation, instability, and chaos. Recent understanding of these complex flows is based largely on grossly simplified models which capture in outline just a few pertinent microscopic features, such as coupling between stresses and other order parameters such as concentration. The role of `structural memory' (the dependence of structural parameters such as the micellar length distribution on the flow history) in explaining these highly nonlinear phenomena is addressed. Structural memory also plays an intriguing role in the little-understood shear-thickening regime, which occurs in a concentration regime close to but below the onset of strong entanglement, and which is marked by a shear-induced transformation from an inviscid to a gelatinous state.

description: Σκοπός της παρούσης μελέτης είναι η εξέταση και μελέτη των στοιχείων που συνθέτουν αυτό που αποκαλούμε ελληνικό «εθνικό χαρακτήρα». Με αφορμή το έργο του Απόστολου Βακαλόπουλου Ο χαρακτήρας των Ελλήνων. Ανιχνεύοντας την εθνική μας ταυτότητα, επιχειρώ να υποστηρίξω ότι ο εθνικός χαρακτήρας των Ελλήνων -και όχι μόνον των Ελλήνων- αποτελεί στην ουσία προϊόν κοινωνικής κατασκευής. Η εργασία εστιάζει σ’ ένα κομμάτι της κατασκευαστικής διαδικασίας και, συγκεκριμένα, στην οπτική των βρετανών περιηγητών που επισκέφθηκαν την Ελλάδα στη διάρκεια του 19ου αιώνα και στην εικόνα που σχημάτισαν για τους Έλληνες.
description: The purpose of this dissertation is to investigate the pieces that compose, what we refer to as “Greek national character”. Occasioned by the book of Apostolos Bakalopoulos The Character of Greeks. Tracing our National Identity, I am trying to support that the national character of Greeks -actually of all nations- is nothing more than a product of social construction. This dissertation focuses in one part of this procedure that has to do with the British traveler’s aspect of 19th century Greece and the image they created for its people.

description: Το μοντέλο του δικαστηρίου αντιμετώπισης ουσιών (Drug treatment courts -DTC-) σχεδιάστηκε από την ανάγκη να επιλυθούν τα πολυάριθμα και δύσκολα προβλήματα που δημιουργούν τα σχετικά με τα ναρκωτικά κρούσματα στα δικαστικά συστήματα. Θεωρείται γενικά ως δικαστήριο που ασχολείται ειδικά με παραβάτες οι οποίοι έχουν διαπράξει αδικήματα υπό την επήρεια ουσιών και αποτελεί εναλλακτική λύση της φυλάκισης. Τα DTC χρησιμοποιούν μια διεπιστημονική ομάδα που περιλαμβάνει δικαστές, εισαγγελείς, δικηγόρους, φορείς παροχής θεραπείας, εκπαιδευτικούς και εμπειρογνώμονες. Τα συστήματα ποινικής δικαιοσύνης και υγειονομικής περίθαλψης συνεργάζονται για να παρέχουν στους εξαρτώμενους δράστες, μηχανισμούς για να ανακάμψουν από την τοξικομανία και να τους οδηγήσουν σε μια παραγωγική και χωρίς εγκλήματα ζωή. Σκοπός της παρούσας εργασίας είναι να διερευνήσει τα δικαστήρια θεραπείας (Δ.Θ.) και στη συνέχεια να παρουσιάσει τα πορίσματα από έρευνες που έχουν διεξαχθείκαι δημοσιευτεί στην Αμερική. Η εργασία ολοκληρώνεται με σύντομη περιγραφή της κατάστασης στην Ελλάδα μέσα από το νόμο 4139/2013 και μερικές σκέψεις πάνω στη λειτουργία των Δ.Θ.
description: The drug treatment court model (DTC) model was conceived out of the need to solve the numerous and intractable problems that drug-related cases create for court systems. A DTC is generally seen as a court that deals specifically with offenders who have committed offenses while under the influence of drugs and provides an alternative to incarceration. DTCs make use of a multidisciplinary team involving judges, prosecutors, defense attorneys, probation officers, treatment providers, and educational and vocational experts. The purpose of this paper is to explore the concept of DTCs, to make evaluation of their effectiveness through research (meta-analysis of surveys and comparative study of cases brought to the specialized courts). The paper concludes a description of the criminal justice system for crimes due to dependencies in Greece through the law of 4139/2013 and a few thoughts over DTC programs.

description: We consider the classical Yang-Mills system coupled with a Dirac equation in 3+1 dimensions. Using that most of the nonlinear terms fulfill a null condition we prove local well-posedness for data with minimal regularity assumptions. This problem for smooth data was solved forty years ago by Y. Choquet-Bruhat and D. Christodoulou. Our result generalizes a similar result for the Yang-Mills equation by S. Selberg and A. Tesfahun.
