description: The observed stellar initial mass function (IMF) appears to vary, becoming bottom-heavy in the centres of the most massive, metal-rich early-type galaxies. It is still unclear what physical processes might cause this IMF variation. In this paper, we demonstrate that the abundance of deuterium in the birth clouds of forming stars may be important in setting the IMF. We use models of disc accretion onto low-mass protostars to show that those forming from deuterium-poor gas are expected to have zero-age main sequence masses significantly lower than those forming from primordial (high deuterium fraction) material. This deuterium abundance effect depends on stellar mass in our simple models, such that the resulting IMF would become bottom-heavy - as seen in observations. Stellar mass loss is entirely deuterium-free and is important in fuelling star formation across cosmic time. Using the EAGLE simulation we show that stellar mass loss-induced deuterium variations are strongest in the same regions where IMF variations are observed: at the centres of the most massive, metal-rich, passive galaxies. While our analysis cannot prove that the deuterium abundance is the root cause of the observed IMF variation, it sets the stage for future theoretical and observational attempts to study this possibility.

description: Η εργασία πραγματεύεται το θέμα της καταχρηστικής καταγγελίας και της ανάγκης προστασίας του εργαζομένου, η οποία εξασφαλίζεται με την πρόβλεψη περιορισμών στο δικαίωμα καταγγελίας του εργοδότη, όπως αυτοί αναλύονται στο πρώτο κεφάλαιο. Η παρέμβαση της νομολογίας κρίθηκε αναγκαία με οδηγό τη διάταξη του άρθρου 281 Α.Κ., η οποία απαγορεύει την καταχρηστική άσκηση του δικαιώματος. Οι περιπτώσεις καταχρηστικής συμπεριφοράς από πλευράς εργοδότη όπως η κακόβουλη καταγγελία και η αντικειμενικά αδικαιολόγητη καταγγελία αποτέλεσαν το μεγαλύτερο μέρος ενασχόλησης της παρούσας εργασίας ενώ η έρευνα της καταχρηστικής εργοδοτικής συμπεριφοράς ολοκληρώνεται με την αρχή της «ultima ratio». Αντικείμενο μελέτης αποτέλεσαν και οι συνέπειες που επέρχονται από το ακύρως ασκηθέν δικαίωμα της καταγγελίας από πλευράς εργοδότη, ενώ τέλος, εξετάστηκαν ζητήματα δικονομικού χαρακτήρα όπως ο τρόπος προβολής της ακυρότητας της καταγγελίας, το βάρος απόδειξης της καταχρηστικότητας της καταγγελίας και το δικαίωμα παραίτησης από το δικαίωμα προσβολής του κύρους.
description: This study deals with the subject of employees’ abusive dismissal and their need of protection, which is ensured by providing restrictions in the employer’s right of dismissal, as these restrictions are analyzed in the first chapter. The case-law’s intervention and interpretation of article 281 of Civil Code, which actually prohibits the abuse of the employer’ s right, was necessary. The cases of employers’ abusive behaviors, including malicious or objectively unjustified dismissals, are the main occupation of this study while the research of employers’ abusive behavior concludes in explaining the principle of «ultima ratio». The consequences which an employer may have to deal when exercising illegally his right of dismissal are also part of this study and finally procedural character issues are examined, such as the way that the objection of invalid dismissal should take place, which part carries the burden to prove the abusiveness of the dismissal and the right to waive from the right of insulting the validity of the dismissal.

description: Σκοπός της διατριβής ήταν η μελέτη της έννοιας της ηγεμονίας στον Machiavelli και στον Gramsci. Αρχικά, κρίναμε σκόπιμο να παρουσιάσουμε περιληπτικά το ιστορικό πλαίσιο και τους παράγοντες εκείνους - πολιτικούς, κοινωνικούς, οικονομικούς, κ. ά - οι οποίοι οδήγησαν τους δυο πολιτικούς στοχαστές στην ανάπτυξη της έννοιας της ηγεμονίας. Κατόπιν, προχωρήσαμε βαθύτερα και εξετάσαμε την έννοια της ηγεμονίας σε σχέση με άλλες έννοιες οι οποίες κατέχουν σημαντική θέση στην οικοδόμηση των θεωριών των δυο πολιτικών στοχαστών. Μέσα από την παραπάνω διαδικασία θέλαμε να κάνουμε εμφανή την πολυπλοκότητα της έννοιας της ηγεμονίας, τους τρόπους και τους λόγους που αυτή μετασχηματίστηκε μέσα στο χρόνο αλλά και στο πώς πήρε την μακιαβελλική και γκραμσιανή μορφή της. Δεν θα μπορούσαμε να παραλείψουμε τις διάφορες κριτικές που ασκήθηκαν στις δυο θεωρίες περί ηγεμονίας αλλά και να προβούμε σε μια σύγκριση μεταξύ των δυο φιλοσόφων. Τέλος, παρουσιάσαμε την δική μας κριτική για τον σύγχρονο ηγεμόνα του Gramsci και για τον μακιαβελλικό ηγεμόνα και προσπαθήσαμε να τοποθετήσουμε τις δυο αυτές θεωρίες στο σήμερα, διερευνώντας αν μπορούν να αποτελέσουν εργαλείο για την αλλαγή του υπάρχοντος.
description: The aim of the present thesis was the study of the concept of hegemony according to Machiavelli and Gramsci. Firstly, we considered it would be appropriate to present a summary of the historical context and the factors –political, social, economic etc –which led both political thinkers to develop the concept of hegemony. Then, we proceeded to further examine the concept of hegemony in comparison with other concepts which are of importance in the construction of the theories of those two thinkers. Through this procedure we wanted to emphasize not only the complexity of the concept of hegemony but also the various ways and the reasons why it was transformed in the course of time; furthermore, how it acquired its Machiavellian and Gramscian form. Moreover, we included the various critiques concerning these two theories of hegemony and compared and contrasted these two philosophers. Finally, we presented our own critique of the modern prince of Gramsci and Machiavelli’s Prince. We tried to examine these two theories in view of the current historical context and explored the possibility of them being a tool in the reform of the existing political system.

description: We estimate in Lp the maximal Riesz transform in terms of the Riesz transform itself for p greater than 1. In the limiting case p=1 the weak L1 inequality is shown to fail. Surprisingly, the weak L1 inequality for the maximal Beurling transform in terms of the Beurling transform does hold.

description: Many approaches have arisen for inferring the evolutionary dynamics of tumour cell populations from point-mutation and copy-number data. However, there are currently no methods that incorporate structural variants (SVs). We present a method, SVClone, for inferring the subclonal make-up of tumour samples using large-scale genomic rearrangements obtained from whole-genome sequencing data. This approach is particularly useful for cancers driven by structural variation, such as prostate cancer.

description: We use in vivo whole-cell electrophysiology to understand cellular and synaptic mechanisms post-spreading depolarization. Our findings provide the first in vivo whole-cell phenotype of cortical spreading depression. We show that spontaneous synaptic activity at the single-cell level is drastically reduced after the depolarization and intrinsic membrane properties are affected to a lesser extent.
Town and gown : the early history of the Vancouver Institute
Creators: name: Damer, Eric John
Publisher: name: University of British Columbia
Year: 2009

description: "Town and Gown: The Early History of The Vancouver Institute" is about the establishment and first twenty-three years of that adult education institution. It explores the social roots that help explain the creation of The Vancouver Institute in 1916, and follows its administrative development until 1939. The thesis argues that the initial promoters held mutually compatible interests that encouraged the growth of the institution, but later promoters were forced to decide not only on the Institute's physical location, but its symbolic association as well. The final decision was, to some extent, a political victory for those who held a particular view of The Vancouver Institute's proper social location.

description: Rapid and precise diagnosis of COVID-19 is one of the major challenges faced by the global community to control the spread of this overgrowing pandemic. In this paper, a hybrid neural network is proposed, named CovTANet, to provide an end-to-end clinical diagnostic tool for early diagnosis, lesion segmentation, and severity prediction of COVID-19 utilizing chest computer tomography (CT) scans. A multi-phase optimization strategy is introduced for solving the challenges of complicated diagnosis at a very early stage of infection, where an efficient lesion segmentation network is optimized initially which is later integrated into a joint optimization framework for the diagnosis and severity prediction tasks providing feature enhancement of the infected regions. Moreover, for overcoming the challenges with diffused, blurred, and varying shaped edges of COVID lesions with novel and diverse characteristics, a novel segmentation network is introduced, namely Tri-level Attention-based Segmentation Network (TA-SegNet). This network has significantly reduced semantic gaps in subsequent encoding decoding stages, with immense parallelization of multi-scale features for faster convergence providing considerable performance improvement over traditional networks. Furthermore, a novel tri-level attention mechanism has been introduced, which is repeatedly utilized over the network, combining channel, spatial, and pixel attention schemes for faster and efficient generalization of contextual information embedded in the feature map through feature re-calibration and enhancement operations. Outstanding performances have been achieved in all three-tasks through extensive experimentation on a large publicly available dataset containing 1110 chest CT-volumes that signifies the effectiveness of the proposed scheme at the current stage of the pandemic.

description: The present study investigated the relationship between the self-concept of Greek adolescents and their parents' marital status (married vs. divorced). 332 adolescents (166 adolescents from intact and 166 from divorced families) 15-16 years old, students in the first grade of the Lyceum, completed a) Hurter’s Self-Perception Profile for Adolescents, b) a questionnaire about their parents' relationship and their own relationship with each one of their parents, and finally c) a questionnaire about demographics. The results suggest that parental divorce is associated with adolescents' self-concept. Adolescents from intact families had higher scores in Behavioral Conduct compared to the adolescents from divorced families. Furthermore, it was found that the boys from intact families had higher scores in Scholastic Competence and Close Friendship compared to the boys from divorced families. It was also found that in adolescents from divorced families some dimensions of self-concept such as Behavioral Conduct and Global Self-Worth are correlated positively with the adolescents' relationships with their stepfather.

description: It is of great interest to approach the mental image 01 space mat a visually impaired has and to study the general function and orientation in his/her environment and to estimate the environmental knowledge. Towards this goal a research was conducted with the participation of blinds in Thessalonica implementing 2 methods. The first method is based to the answers of a questionnaire and the second to the experimental investigation through the description and design of elements found in space. Although the statistical sample of the research was relatively small on the other hand some basic conclusions were made regarding the knowledge of the shape and structure of their environment. A more analytical processing and study of the parameters can contribute to a future examination and coverage of the subject as well as to the development of methods towards the environmental education of blind people.

description: We study correlation functions in five-dimensional non-Lorentzian theories with an $SU(1,3)$ conformal symmetry. Examples of such theories have recently been obtained as $Ω$-deformed Yang-Mills Lagrangians arising from a null reduction of six-dimensional superconformal field theories on a conformally compactified Minkowski space. The correlators exhibit a rich structure with many novel properties compared to conventional correlators in Lorentzian conformal field theories. Moreover, identifying the instanton number with the Fourier mode number of the dimensional reduction offers a hope to formulate six-dimensional conformal field theories in terms of five-dimensional Lagrangian theories. To this end we show that the Fourier decompositions of six-dimensional correlation functions solve the Ward identities of the the $SU(1,3)$ symmetry, although more general solutions are possible. Conversely we illustrate how one can reconstruct six-dimensional correlation functions from those of a five-dimensional theory, and do so explicitly at 2- and 3-points. We also show that, in a suitable decompactification limit $Ω\to 0$, the correlation functions become those of the DLCQ description.

description: Although tensor models are serious candidates for a theory of quantum gravity, a connection with classical spacetimes have been elusive so far. This paper aims to fill this gap by proposing a neat connection between tensor theory and Euclidean gravity at the classical level. The main departure from the usual approach is the use of Schur invariants (instead of monomial invariants) as manifold partners. Classical spacetime features can be identified naturally on the tensor side in this new setup. A notion of locality is shown to emerge through Ward identities, where proximity between spacetime points translates into vicinity between Young diagram corners.

Women’s agency and educational policy : The experiences of the women of Kilome-Kenya
Creators: name: Kiluva-Ndunda, Mutindi Mumbua
Publisher: name: University of British Columbia

description: This study examines women’s experiences of formal education in Kenya. The study aims at making visible the cultural, historical, economic and political factors that shaped, and continue to shape, women’s educational and employment opportunities. It also highlights women’s agency exemplified in their struggle to provide their children, and particularly their daughters, with educational opportunities. The study draws attention to the gender and power issues that limit women’s participation in the public sphere. These are issues that policy makers, politicians, and development agents have not and still do not adequately address. The study employs post-positivist research methodologies, particularly feminist methodologies informed by post-colonial critiques. The women in this study are treated as social agents not as victims of men, and of economic and political trends. The women formulate strategies aimed at influencing or shaping the social system in which they are a part. The women’s agency resides in their individual and communal endeavours and is constantly reinvented in the context of political and social change. This research is an analysis of the experiences of 38 women born, raised and partly schooled in Kilome division, Makueni district. It focuses on the educational experiences of rural women living in two villages and a small town in Kilome division, Kenya. I use the women’s discourse to critique the public discourse on education articulated in policy documents produced in the last 30 years since independence in 1963. This study illustrates how women in Kenya have been largely absent at the national level where educational policies are formulated. Policy making has remained male dominated. Policy makers, charged with structuring and restructuring education to meet the country’s development needs, continue to limit women’s agency to the private sphere. The formulation of policies from the male perspective has intensified the public and private dichotomy. Absent in the public discourse on education has been the discussion of how gender, a social construction, has influenced opportunities available to men and women in colonial and post-colonial Kenya. Colonial gender constructions of femininity have continued to limit educational opportunities made available to women in post-colonial Kenya. The Kenyan women in this study are cognizant of how these gendered assumptions shaped, and continue to shape, women’s educational and employment opportunities. They re-negotiate and resist these gendered assumptions and they have become intervention agents for their children’s education. The women’s agency, however, is limited by their lack of economic power. The interplay between gendered cultural assumptions about femininity and the increased costs of schooling imposed by policy makers continue to have a negative impact on women’s education.
Classical-Quantum Mappings for Geometrically Frustrated Systems: Spin Ice in a [100] Field

description: Certain classical statistical systems with strong local constraints are known to exhibit Coulomb phases, where long-range correlation functions have power-law forms. Continuous transitions from these into ordered phases cannot be described by a naive application of the Landau-Ginzburg-Wilson theory, since neither phase is thermally disordered. We present an alternative approach to a critical theory for such systems, based on a mapping to a quantum problem in one fewer spatial dimensions. We apply this method to spin ice, a magnetic material with geometrical frustration, which exhibits a Coulomb phase and a continuous transition to an ordered state in the presence of a magnetic field applied in the [100] direction.

Έτσι, από τη μία, η εκπληκτική εξέλιξη της τεχνολογίας δημιούργησε δυνατότητες που μπορούν να διαβάλλουν το δικαίωμα στην επικοινωνία, στοιχειοθετώντας με τον τρόπο αυτό απειλή για την ιδιωτικότητα του ατόμου. Από την άλλη, η παρέμβαση των δημοσίων αρχών στην προσωπική ζωή, ακόμη και υπό τις συνθήκες άρσεως της απαγόρευσης, οφείλει να συνοδεύεται από επαρκείς εγγυήσεις που δεν συνιστούν κατάχρηση εξουσίας.

description: The guarantee for the secrecy of correspondence, as part of the right to respect for private and family life, has represented and still represents a constant issue for domestic and international law. Thus, on one hand, the amazing evolution of technology has created possibilities for breaking the right to the secrecy of communication, thus constituting a threat to individual’s private life. On the other hand, the interference of the public authorities in the private life, made on reasonable grounds, should be accompanied by guarantees indicting that there is no abuse of power. To this study we intent to make an analysis of the regulations, mainly the internal ones, via a contemporary explanatory approach.

description: The new education reform, carried out in the 1998- 2000 (pedagogical i Institute, 1998:10), introduced for the first time in the history of Greek education a corpus of curricula which included clearly stared teaching principles and goals for every subject, the contents of subjects divided into units, the objectives that have to be fulfilled in every teaching unit in relation to the subject aims, and finally the methods and the means which arc necessary in order to attain the desired objectives. This corpus is called "unified framework of curricula" and constitutes an attempt to induce a new perspective about the construction of knowledge by broadening the orientation of the teaching material and by avoiding overlapping or sterile recycling. Today, after two years of implementation of the new Language Curriculum in public preschool education, we try to elucidate the opinions, the perceptions and the attitudes of Greek preschool teachers towards the curriculum and to explore the potential of its induction in public preschool education. Our research tool was a questionnaire consisting of 56 items. The sample consisted of 250 nursery teachers. The research findings showed that nursery teachers adapted satisfactorily to the new Language Curriculum and they did not faced any particular problems during its implementation. Moreover, teachers produced appropriate teaching activities based on the directives of the Greek Pedagogical Institute and they seem to understand fully the linguistic prerequisites, which are necessary for the implementation of the new Language Curriculum.

Periodic oscillations were observed in magnetic fields above 45-58 kOe, corresponding to dense-dilute boundary for Josephson vortex lattice. The observed period of oscillations, agrees well with the increase of one fluxon per two junctions ($H_{p}$\textit{=$Φ$}$_{0}$\textit{/2Ls}), may correspond to formation of a triangular lattice of Josephson vortices as has been reported by Ooi et al. for highly anisotropic (larger than 200) Bi-2212 intrinsic Josephson junctions.

description: his paper presents findings from the research investigating the skills and knowledge in Mathematics of Cypriot pupils entering primary school. A performance test, which was designed to assess skills and knowledge in Mathematics identified in the Curriculum of Primary Education in Cyprus, was administered to a representative sample of pupils in Year J (N=835). Teachers were also asked to complete a report for each pupil. The most important findings were as follows. First, the skills included in the curriculum were differentiated into those which more than 75% of pupils entering primary schools had achieved and those which more than 30% of pupils entering primary school had not achieved. Second, significant differences among the skills and knowledge of the whole group of pupils entering primary school have been identified. Third, cluster analysis revealed five relatively homogeneous groups of pupils according To their different knowledge and skills in Mathematics. Fourth, a correlation was identified between findings gathered from the performance test and from teachers' assessment of pupils' skills in Mathematics. Implications for the development of a national policy on baseline assessment are drawn.

description: An analysis of the world's neutrino oscillation data, including sterile neutrinos, (M. Sorel, C. M. Conrad, and M. H. Shaevitz, Phys. Rev. D 70, 073004) found a peak in the allowed region at a mass-squared difference $Δm^2 \cong 0.9$ eV$^2$. We trace its origin to harmonic oscillations in the electron survival probability $P_{ee}$ as a function of L/E, the ratio of baseline to neutrino energy, as measured in the near detector of the Bugey experiment. We find a second occurrence for $Δm^2 \cong 1.9$ eV$^2$. We point out that the phenomenon of harmonic oscillations of $P_{ee}$ as a function of L/E, as seen in the Bugey experiment, can be used to measure the mass-squared difference associated with a sterile neutrino in the range from a fraction of an eV$^2$ to several eV$^2$ (compatible with that indicated by the LSND experiment), as well as measure the amount of electron-sterile neutrino mixing. We observe that the experiment is independent, to lowest order, of the size of the reactor and suggest the possibility of a small reactor with a detector sitting at a very short baseline.

description: The aim of the thesis was to study the parameters for creating and running a company in the field of Organic Electronics. The technology that can be used for the production of Organic Electronics is examined and described and estimated the costs of installing and operating the business. We described the current market situation for Organic Electronics. We described additionally the enterprises involved either as manufacturers of raw materials or as machinery manufacturers either as manufacturers of finished products. We made a SWOT analysis of the enterprise and examined the strengths and weaknesses as well as the difficulties and opportunities. Taking into account the estimates of installation costs, operating costs and manpower as well as the estimated sales and revenues, we estimated the cash flows and the capital required by the company to start to profits from its operation.
A Metamaterial Homogenization Approach with Application to the Characterization of Microstructured Composites with Negative Parameters

description: In this work, we develop a new systematic and self-consistent approach to homogenize arbitrary non-magnetic periodic metamaterials. The proposed method does not rely on the solution of an eigenvalue problem and can fully characterize the effects of frequency dispersion, magneto-electric coupling, and spatial dispersion, even in frequency band-gaps or when the materials are lossy. We formulate a homogenization problem to characterize a generic microstructured artificial material, and demonstrate that it is equivalent to an integral-differential system. We prove that this complex system can be reduced to a standard integral equation and solved using standard methods. To illustrate the application of the proposed method, we homogenize several important metamaterial configurations involving split ring resonators and metallic wires.

description: We present an evolutionary population synthesis model of the surface brightness fluctuation (SBF) for normal and He-enriched simple stellar populations (SSPs). While our SBF model for the normal-He population agrees with other existing models, the He-rich population, containing hotter horizontal-branch stars and brighter red-clump stars than the normal-He population, entails a substantial change in the SBF of SSPs. We show that the SBF magnitudes are affected by He-rich populations at least $\sim$0.3~mag even in $I$- and near-IR bands at given colors, from which the SBF-based distances are often derived. Due to uncertainties both in observations and models, however, the SBFs of Galactic globular clusters and early-type galaxies do not allow verifying the He-enriched model. We propose that when combined with independent metallicity and age indicators such as ${\rm Mg}_2$ and ${\rm H}β$, the UV and optical SBFs can readily detect underlying He-rich populations in unresolved stellar systems at a distance out to $\gtrsim 20$\,Mpc. A full set of the spectro-photometric and SBF data for SSPs from the Yonsei Evolutionary Population Synthesis (YEPS) model is available for download at http://cosmic.yonsei.ac.kr/YEPS.htm.

description: O estudo de reações químicas é voltado para o processo de identificação e classificação de reações. Nesse sentido, o processo para obter tal conhecimento é um dos mais complexos para muitos alunos do ensino médio brasileiro, pois a forma como os conteúdos são ministrados impactam diretamente no ensino e na aprendizagem do aluno. Com isso, a utilização de recursos didáticos de forma a contextualizar o ensino ao cotidiano se apresenta como uma forma a ajudar na compreensão dos assuntos ministrados em sala de aula.Assim, o objetivo deste estudo foi analisar, a partir de pesquisa bibliográfica, como o processo de ensino-aprendizagem dos alunos pode ser desenvolvido com o uso de TDICS, em especial o uso de aplicativos como recurso didático para o estudo de reações químicas.

description: The aim of the present thesis was to write a hygiene guide referring to all the necessaries measures which have to be taken in a company which process and trades fishes and molluscs. The present study investigates also, the effectiveness of detergents and disinfectants used extensively in fish processing industries. We attempt to evaluate the effect of temperature and processing to the formation of histamine in fishes such as mackerel and herring. Similarly we tried to estimate the acidification speed in different consistency fish(mackerel) and mollusc(octopus). Finally, we evaluate fish processing practices such as salting and fumigation in order to increase their shelf life.

description: The interactions of ultra-high energy cosmic rays (UHECRs) with background photons in extragalactic space generate high-energy neutrinos and photons. Simulating UHECR propagation requires assumptions about physical quantities such as the spectrum of the extragalactic background light (EBL) and photodisintegration cross sections. These assumptions, as well as the approximations used in the codes, may influence the computed predictions both of cosmic-ray spectra and composition, and of cosmogenic neutrino and photon fluxes. Following up on our previous work where we studied the resulting uncertainties on cosmic-ray simulations, here we quantify those on neutrinos and photons, using the Monte Carlo codes CRPropa and SimProp in various source scenarios. We discuss the results in the light of the constraining power of the neutrino and photon spectra on the origin of the UHECRs. We show that cosmogenic neutrino fluxes are more sensitive to the parametrization of the EBL than UHECR spectra, whereas the overall cosmogenic gamma-ray production rates are relatively independent on details of the propagation. We also find large differences between neutrino fluxes predicted by the latest released versions of CRPropa and SimProp, and discuss their causes and possible improvements in future versions of the codes.

description: This study investigates students' and teachers' attributions of causality for the difficulties and failure of the students in written speech and mathematics. The sample included 706 students of 8th grade and 43 teachers of 8th grade. They were asked to fill out a questionnaire in which they have to indicate the attributed causes of students' learning difficulties in written speech and mathematics. The results showed that students attributed their difficulties to the difficulty of the material, to their teachers and to themselves, while teachers tend to attribute the difficulties of students to causes external to them.

description: I show how to perform a Loschmidt echo (time reversal) in the Bose-Hubbard model implemented with cold bosonic atoms in an optical lattice. The echo is obtained by applying a linear phase imprint on the lattice and a change in magnetic field to tune the boson-boson scattering length through a Feshbach resonance. I discuss how the echo can measure the fidelity of the quantum simulation, the intensity of an external potential (e.g. gravity), or the critical point of the superfluid-insulator quantum phase transition.
