Developmental Language Disorder (DLD)
Verbs with alternating transitivity
Unaccusative verbs
Sentence repetition

description: The purpose of this thesis is to investigate the repetition of sentences containing unaccusative verbs by children with Developmental Language Disorder (DLD). Children with DLD have been shown to be impaired in the use of constructions involving movement, such as reversible passives and relative sentences. Unaccusative verbs present an interesting dichotomy, in that they can surface with nonactive morphology, and as such have the same surface structure as other non-active constructions, but different deep structures; unaccusative verbs with active morphology move their deep – structure object to the subject position. Therefore, it is hypothesised that children with DLD will have problems producing and understanding sentences containing unaccusative verbs with active morphology, but not ones with passive, relative to their typically developing (TD) peers.
description: Ο σκοπός της παρούσας διπλωματικής εργασίας είναι να ερευνήσει την επανάληψη προτάσεων που περιέχουν αναιτιατικά ρήματα από παιδιά με Αναπτυξιακή Γλωσσική Διαταραχή (ΑΓΔ). Τα παιδιά με ΑΓΔ δείχνουν να έχουν ελλείμματα στη χρήση συντακτικών δομών που παράγονται με μετακίνηση, όπως τα παθητικά ρήματα (που έχουν αντίστοιχο ενεργητικής φωνής) και οι αναφορικές προτάσεις. Τα αναιτιατικά ρήματα παρουσιάζουν ενδιαφέρον λόγω της διττής τους δομής, καθώς μπορούν να εμφανίζονται με μη ενεργητική μορφολογία, και έτσι να έχουν την ίδια επιφανειακή δομή με άλλες μη ενεργητικές δομές, αλλά διαφορετική βαθιά δομή. Τα αναιτιατικά ρήματα με ενεργητική μορφολογία μετακινούν το αντικείμενο της βαθιάς δομής τους σε θέση υποκειμένου. Επομένως, σχηματίζεται η υπόθεση ότι τα παιδιά με ΑΓΔ θα έχουν δυσκολίες στην παραγωγή και κατανόηση προτάσεων που περιέχουν αναιτιατικά ρήματα ενεργητικής μορφολογίας, αλλά όχι στα αντίστοιχα παθητικής, σε σύγκριση με τυπικά αναπτυσσόμενους συνομηλίκους τους.

description: Η εργασία πραγματεύτηκε τη διδασκαλία στρατηγικών ανάγνωσης στα Αγγλικά σε μικρούς μαθητές και εξετάζει την αποτελεσματικότητά τους με τη χρήση αυθεντικών ή προσαρμοσμένων ιστοριών. Έρευνες έχουν δείξει ότι οι μικροί μαθητές μπορούν να διδαχθούν στρατηγικές «από πάνω προς τα κάτω» και «από κάτω προς τα πάνω» ώστε να βελτιώσουν τις δεξιότητες κατανόησης κειμένου. Μερικές από αυτές τις στρατηγικές είναι η πρόβλεψη, η ενεργοποίηση προϋπάρχουσας γνώσης, η οπτικοποίηση, η άσκηση της μνήμης, η συναγωγή συμπερασμάτων, η γρήγορη και ανιχνευτική ανάγνωση. Η εργασία εξέτασε την πρόοδο στην Αγγλική γλώσσα 7 μικρών μαθητών (επιπέδου Α1) μέσα από εμπειρική παρατήρηση και ανάλυση έργου. Οι μαθητές ολοκλήρωσαν ασκήσεις σχετικά με την εφαρμογή στρατηγικών και πήραν μέρος σε τεστ πριν και μετά τη διδασκαλία των στρατηγικών. Τέλος, απάντησαν σε μία σειρά ερωτήσεων κατανόησης ανοιχτού και κλειστού τύπου. Τα αποτελέσματα της εργασίας αυτής έδειξαν πως οι μαθητές είχαν καλύτερη επίδοση στις ερωτήσεις κατανόησης όταν δέχονται καθοδήγηση για τη χρήση συγκεκριμένων στρατηγικών. Τέλος, οι μαθητές εκδήλωσαν θετική διάθεση απέναντι στη χρήση στρατηγικών
description: The thesis dealt with the issue of teaching reading strategies to young learners of English and explored their effectiveness with the use of a number of English texts and different types of comprehension questions. Research on this field has shown that young learners can be taught to use top-down and bottom-up strategies in order to improve their reading comprehension skills. Learners should be trained to employ strategies such as prediction, activation of background knowledge, imagery, memory, inferencing, skimming and scanning. It is particularly important that learners are trained to be able to guess the meaning of unknown words and phrases that appear in the texts and at the same time control any affective factors that can influence them. Through empirical observation and task analysis this thesis explored the progress in the reading strategies employed by 7 young learners of English (Level A1-Α2) who were explicitly taught some reading strategies by means of in-class tasks. Their progress was checked with tests administered before and after the instructional interventions (pre- and post-testing). Results showed that explicit strategy instruction helped improve the learners’ performance in reading comprehension tasks more than implicit instruction. Explicit strategy instruction also led to the learners’ adopting positive attitudes towards strategy use

description: With the ongoing AKARI infrared sky survey, of much greater sensitivity than IRAS, a wealth of post-AGB objects may be discovered. It is thus time to organize our present knowledge of known post-AGB stars in th galaxy with a view to using it to search for new post-AGB objects among AKARI sources. We searched the literature available on the NASA Astrophysics Data System up to 1 October 2006, and defined criteria for classifying sources into three categories: "very likely", "possible" and "disqualified" post-AGB objects. The category of "very likely" post-AGB objects is made up of several classes. We have created an evolutionary, on-line catalogue of Galactic post-AGB objects, to be referred to as "The Torun catalogue of Galactic post-AGB and related objects". The present version of the catalogue contains 326 "very likely", 107 "possible" and 64 "disqualified" objects. For the very likely post-AGB objects, the catalogue gives the available optical and infrared photometry, infrared spectroscopy and spectral types, and links to finding charts and bibliography.

Spread of P elements in drosophila melanogaster
Creators: name: Meister, Gerald Alan
Publisher: name: University of British Columbia
Year: 2009

description: Several experiments suggest that P elements spread in mixed P-M populations. These experiments monitored the spread of the ability of flies to induce and to suppress gonadal dysgenesis. Such experiments, based on physiological phenotypes and providing no molecular data, are unable to distinguish between the "dispersal" and "copy number accumulation" aspects of P element spread. This thesis describes several experiments undertaken to gain a fuller understanding of the various components of P element spread. The invasion of P elements in natural populations of Drosophila melanogaster was modelled by establishing laboratory populations with 0.5% and 5% P genomes. Two replicate populations at each frequency were monitored over twenty generations. The percentage of genomes that contained P elements was followed by single fly ovary blots at each generation for all populations. The distribution of P elements among individual flies was monitored by single fly Southern blots at even numbered generations from 6 to 20 for the two populations initiated with 5% P genomes. This analysis of the molecular dispersal of P elements is compared to the spread of the physiological phenotypes demonstrated by a collaborating lab. Our results show that the frequency of flies containing P elements increased each generation. The number of P elements within individual genomes decreased initially, but then increased to equal or surpass the number of elements in the parental P strain. Finally, the distribution of P elements within the genomes of individuals from later generations varied considerably, and this pattern differed from the original P strain. These results suggest that the interaction between the assortment and recombination of chromosomal segments, and some form of multiplicative transposition could result in the rapid spread of P elements in natural populations.

Για το λόγο αυτό, πραγματοποιήσαμε μια διαδικτυακή έρευνα, στην οποία συμμετείχαν 162 δημοσιογράφοι. Τα αποτελέσματα έδειξαν ότι τόσο τα χαρακτηριστικά της δημοσιογραφικής εργασίας όσο και οι αντιλήψεις των δημοσιογράφων σχετικά με το ρόλο τους συσχετίζονται έντονα με την επαγγελματική ικανοποίηση των δημοσιογράφων
description: The scope of the dissertation proposal is to examine factors such as Job Content, Payment, Deprivation that correlate to Job Satisfaction among Greek journalists. The key question/problem addressed by the dissertation is whether job satisfaction in journalism differs in accordance to a number of variables, such as, personal/demographical characteristics, job characteristics, journalists' perceptions of their role, and deprivation. For this reason, we conducted an online research in which 162 journalists took part. Results showed that both job characteristics and journalists' perceptions of their role strongly correlate with the journalists’ job satisfaction.

description: We propose two alternative formulations for a three-dimensional non-anticommutative superspace in which some of the fermionic coordinates obey Clifford anticommutation relations. For this superspace, we construct the supersymmetry generators satisfying standard anticommutation relations and the corresponding supercovariant derivatives. We formulate a scalar superfield theory in such a superspace and calculate its propagator. We also suggest a prescription for the introduction of interactions in such theories.

description: We use ZFIRE and ZFOURGE observations with the Spectral Energy Distribution (SED) fitting tool Prospector to reconstruct the star formation histories (SFHs) of proto-cluster and field galaxies at $z\sim 2 $ and compare our results to the TNG100 run of the IllustrisTNG cosmological simulation suite. In the observations, we find that massive proto-cluster galaxies ($\log[{\rm M}_{\ast}/{\rm M}_{\odot}]>$10.5) form $45 \pm 8 \%$ of their total stellar mass in the first $2$ Gyr of the Universe compared to $31 \pm 2 \%$ formed in the field galaxies. In both observations and simulations, massive proto-cluster galaxies have a flat/declining SFH with decreasing redshift compared to rising SFH in their field counterparts. Using IllustrisTNG, we find that massive galaxies ($\log[{\rm M}_{\ast}/{\rm M}_{\odot}] \geq 10.5$) in both environments are on average $\approx190$ Myr older than low mass galaxies ($\log[{\rm M}_{\ast}/{\rm M}_{\odot}]= 9-9.5$). However, the difference in mean stellar ages of cluster and field galaxies is minimal when considering the full range in stellar mass ($\log[{\rm M}_{\ast}/{\rm M}_{\odot}] \geq 9$). We explore the role of mergers in driving the SFH in IllustrisTNG and find that massive cluster galaxies consistently experience mergers with low gas fraction compared to other galaxies after 1 Gyr from the Big Bang. We hypothesize that the low gas fraction in the progenitors of massive cluster galaxies is responsible for the reduced star formation.

description: We introduce TopoCut: a new way to integrate knowledge about topological properties (TPs) into random field image segmentation model. Instead of including TPs as additional constraints during minimization of the energy function, we devise an efficient algorithm for modifying the unary potentials such that the resulting segmentation is guaranteed with the desired properties. Our method is more flexible in the sense that it handles more topology constraints than previous methods, which were only able to enforce pairwise or global connectivity. In particular, our method is very fast, making it for the first time possible to enforce global topological properties in practical image segmentation tasks.

description: We present science highlights and performance from the Swift X-ray Telescope (XRT), which was launched on November 20, 2004. The XRT covers the 0.2-10 keV band, and spends most of its time observing gamma-ray burst (GRB)afterglows, though it has also performed observations of many other objects. By mid-August 2007, the XRT had observed over 220 GRB afterglows, detecting about 96% of them. The XRT positions enable followup ground-based optical observations, with roughly 60% of the afterglows detected at optical or near IR wavelengths. Redshifts are measured for 33% of X-ray afterglows. Science highlights include the discovery of flaring behavior at quite late times, with implications for GRB central engines; localization of short GRBs, leading to observational support for compact merger progenitors for this class of bursts; a mysterious plateau phase to GRB afterglows; as well as many other interesting observations such as X-ray emission from comets, novae, galactic transients, and other objects.

Η υδραζίνη αντιδρά με την ο-φθαλαλδεΰδη (ΟPA) σε όξινο περιβάλλον (pΗ <1,5) και απουσία πυρινόφιλων αντιδραστηρίων, για να σχηματίσει μια έντονα φθορίζουσα υδραζόνη (318/376 nm). Η εφαρμογή ενός σταδίου αναχαίτισης ροής 120 δευτερολέπτων σε αυξημένη θερμοκρασία (70 oC) προσέφερε επαρκή ευαισθησία (LOD = 0,9 μg L-1 ή 0,1 ppm σε στερεό ΑΡΙ) για να ικανοποιήσει τα όρια της φαρμακοποιίας για την επιλεγμένη εφαρμογή. Η υδραζίνη διαχωρίστηκε αποτελεσματικά από την περίσσεια της Αλλοπουρινόλης με απευθείας εκχύλιση στερεής φάσης χρησιμοποιώντας ένα προσροφητικό υλικό υδροφιλικής-λιπόφιλης τεχνολογίας που παρείχε άμεση κατακράτηση της περισσότερο υδρόφοβης Αλλοπουρινόλης χωρίς την ανάγκη βημάτων διαβροχής / ενεργοποίησης. Το ποσοστό ανάκτησης κυμάνθηκε μεταξύ 93,3 και 105,80%.
description: In the present study we report a fully automated method for the determination of low levels of the genotoxic impurity hydrazine in allopurinol active pharmaceutical ingredient (API) and formulations based on the concept of zone-fluidics. Hydrazine reacts on-line with o-phthalaldehyde in a unique way, that is in acidic medium (pH < 1.5) and in the absence of nucleophylic reagents, to form a highly fluorescent hydrazone (318/376 nm). The adaptation of a 120 s long stopped-flow step at elevated temperature (70 oC) offered adequate sensitivity (LOD = 0.9 μg L-1 or 0.1 ppm in the solid API) to meet the pharmacopoeia limits for the selected application. The analyte was separated efficiently from the excess of the API by on line solid phase extraction using a Hydrophilic-Lipophilic technology sorbent that provided direct retention of the more hydrophobic API without the need of wetting/conditioning steps. Percent revoveries ranged between 93.3 and 105.80 %.

description: We show that the classic example of quasiperiodically forced maps with strange nonchaotic attractors described by Grebogi et al and Herman in the mid-1980s have some chaotic properties. More precisely, we show that these systems exhibit sensitive dependence on initial conditions, both on the whole phase space and restricted to the attractor. The results also remain valid in more general classes of quasiperiodically forced systems. Further, we include an elementary proof of a classic result by Glasner and Weiss on sensitive dependence, and we clarify the structure of the attractor in an example with two-dimensional fibers also introduced by Grebogi et al.

description: Analysis and interpretation of the Her X-1 X-ray light curve obtained with the ASM onbord RXTE over the period 1996 February to 2004 September is presented. We report that the features found previously in the averaged X-ray lightcurve are confirmed by the new RXTE/ASM data. In particular, anomalous dips and post-eclipse recoveries in two successive orbits in the short-on state are found to be prominent and stable details of the light curve. We argue that a change of the tilt of the accretion disk over the 35-day period is necessary to account for these features and show that our numerical model can explain such a behavior of the disk and reproduce the observed details of the light curve.

description: Οι τραυματισμοί των οπισθίων μηριαίων έχουν συσχετιστεί με μυϊκή ανισορροπία των καμπτήρων-εκτεινόντων μυών του γόνατος. Ο δικέφαλος μηριαίος ως διαρθρικός μυς , εμπλέκεται στην άρθρωση του ισχίου. Σκοπός της παρούσας έρευνας είναι να εξεταστεί αν η αναλογία ροπής καμπτήρων-εκτεινόντων μυών του ισχίου μεταβάλλεται σε άτομα με προηγούμενο τραυματισμό στους οπισθίους μηριαίους. Για την έρευνα επιλέχθηκαν δύο γκρουπ , 9 υγιείς και 7 άτομα με προηγούμενο τραυματισμό στου οπισθίους μηριαίους. Η μέτρηση έγινε από την ύπτια κατάκλιση. Η γωνιακή ταχύτητα ήταν οι 60°/sec και 180°/sec . Μετρήθηκε η κάμψη και η έκταση σε σύγκεντρη και έκκεντρη συστολή. Με βάση τα δεδομένα αυτά , υπολογίστηκε η αναλογία ροπής καμπτήρων-εκτεινόντων μυών του ισχίου , συγκρίθηκε η αναλογία μεταξύ των δύο ποδιών αλλά και η ποσοστιαία διαφορά μεταξύ των δύο άκρων μεταξύ των δύο γκρουπ. Τα αποτελέσματα δεν έδειξαν κάποια στατιστικά σημαντική διαφορά. Η παρούσα έρευνα με τις κατάλληλες τροποποιήσεις θα μπορούσε να εξαγάγει ένα πιο έγκυρο και αντιπροσωπευτικό αποτέλεσμα για το αν θα πρέπει να εστιάζουμε στην δύναμη των μυών του ισχίου όταν ασχολούμαστε με τον τραυματισμό των οπισθίων μηριαίων. Παλαιότερες έρευνες που ασχολήθηκαν με παθολογία του κάτω άκρου , σχετίζουν την αδυναμία του ισχίου και την μυϊκή ανισορροπία με την εν λόγω παθολογία.
description: Muscle injuries of the hamstrings have been associated with muscle imbalance of the knee flexors and extensors. Biceps femoral, as a 2 joint muscle is greatly involved on the hip joint. The purpose of this research is to find out whether the torque ratio of the hip flexors-extensors is different in people with previous hamstring injury. 2 groups were formed, 9 healthy people and 7 people with a previous injury on the hamstrings. participants were put in the supine position. The angular velocity was 60°/sec and 180°/sec. We measured flexion and extension both in eccentric and concentric contraction. Base on these measurements we formed the torque ratios for both legs for the hip joint. Then we compared the between leg ratios and the percentage difference of the legs between the 2 groups. The results didn’t show any statistical significant difference between the 2 groups. The present study could be more accurate with proper modification and elimination of some limitations, in order to better answer whether we, as clinicians should target on the hip muscle balance when dealing with hamstring injuries.

title: Age Patterns of Mortality within Childhood in Sub-Saharan Africa
Creators: name: Jasseh, M
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2003

description: The age pattern of mortality in sub-Saharan Africa and how it varies across the continent remain poorly understood. The region lacks accurate registration statistics and assumptions about mortality patterns are needed to produce and smooth mortality estimates. These have had to be taken from model life table systems based on non-African data. Birth histories collected in national Demographic and Health Surveys are used to investigate age patterns of mortality in childhood in the sub-national regions of 26 countries of continental Sub-Saharan Africa. The majority of populations display a pattern of higher child relative to infant mortality than in any existing model system, including the Princeton "North" models. This reflects the existence of a "hump" of excess mortality in the late post-neonatal period and second year of life in more than three-quarters of sub-national populations. Age patterns of mortality vary markedly within and between countries, though adjacent parts of neighbouring countries sometimes have similar patterns. Particularly extreme relationships between infant and child mortality are most common in the Sahel, while a coastal belt exists adjoining the Indian Ocean with age patterns of mortality within the range of those in the Princeton models. A three-parameter model, which incorporates this "hump", is fitted to the data using Poisson regression and fitted national life tables are produced. Except for the southwest of Africa, no extensive areas exist with homogenous parameter values for the underlying downward slope of mortality with age in childhood and the size of the "hump" respectively. Thus, the scope for construction of "regional" childhood mortality models is limited. Nevertheless, age patterns of mortality in African populations tend to share features that differ from those of historical Western populations. Thus, using the national and regional average life tables in the indirect estimation of under-5 mortality yields more consistent series of estimates than are obtained using existing models.

description: This thesis begins with the examination of the concept of Ummah before exploring the concept of globalization in combination with the media and how these have impacted on contemporary Muslim perception of Ummah. This study investigates the theological meaning of Ummah and examines its media narrative in the globalized world. It finds that although the theological meaning of Ummah understands Muslims as a whole, it turns to an exclusive concept in terms of media narratives in the globalized world

Αυτή η μελέτη ερευνά το θεολογικό νόημα της Ούμμα και εξετάζει το μιντιακό αφήγημά της στο σημερινό παγκοσμιοποιημένο κόσμο. Η έρευνα ανακαλύπτει ότι παρόλο που η θεολογική σημασία της Ούμμα κατανοεί όλους τους Μουσουλμάνους ως σύνολο, αποδεικνύεται ότι μετατρέπεται σε μια κλειστή έννοια όσον αφορά το μιντιακό της αφήγημα στην εποχή της παγκοσμιοποίησης

description: Derivation of a quantum master equation for a system weakly coupled to a bath which takes into account nonsecular effects, but nevertheless has the mathematically correct Gorini-Kossakowski-Lindblad-Sudarshan form (in particular, it preserves positivity of the density operator) and also satisfies the standard thermodynamic properties is a known long-standing problem in theory of open quantum systems. The nonsecular terms are important when some energy levels of the system or their differences (Bohr frequencies) are nearly degenerate. We provide a fully rigorous derivation of such equation based on a formalization of the weak-coupling limit for the general case.

description: We consider the process of $n$ Brownian excursions conditioned to be nonintersecting. We show the distribution functions for the top curve and the bottom curve are equal to Fredholm determinants whose kernel we give explicitly. In the simplest case, these determinants are expressible in terms of Painlevé V functions. We prove that as $n\to \infty$, the distributional limit of the bottom curve is the Bessel process with parameter 1/2. (This is the Bessel process associated with Dyson's Brownian motion.) We apply these results to study the expected area under the bottom and top curves.

Causal and Epistemic Relevance in Appeals to Authority
Creators: name: Lommi, Sebastiano
Publisher: name: Rivista Italiana di Filosofia Analitica Junior

description: Appeals to authority have a long tradition in the history of argumentation theory. During the Middle Age they were considered legitimate and sound arguments, but after Locke’s treatment in the Essay Concerning Human Understanding their legitimacy has come under question. Traditionally, arguments from authority were considered informal arguments, but since the important work of Charles Hamblin (Hamblin, 1970) many attempts to provide a form for them have been done. The most convincing of them is the presumptive form developed by Douglas Walton and John Woods (Woods, Walton, 1974) that aims at taking into account the relevant contextual aspects in assessing the provisional validity of an appeal to authority. The soundness of an appeal depends on its meeting the adequacy conditions set to scrutinize all the relevant questions. I want to claim that this approach is compatible with the analysis of arguments in terms of relevance advanced by David Hitchcock (Hitchcock, 1992). He claims that relevance is a triadic relation between two items and a context. The first item is relevant to the second one in a given context. Different types of relevance relation exist, namely causal relevance and epistemic relevance. “Something is [causally] relevant to an outcome in a given situation if it helps to cause that outcome in the situation” (Hitchcock, 1992, p. 253), whereas it is epistemically relevant when it helps to achieve an epistemic goal in a given situation.  I claim that we can adapt this conception to Walton and Krabbe’s theory of dialogue type (Walton, Krabbe, 1995), seeing the items of a relevance relation as the argument and its consequence and the context as the type of dialogue in which these arguments are advanced. According to this perspective, an argument from authority that meets the adequacy conditions has to be considered legitimate because it is an epistemically relevant relation.  Therefore, my conclusion is that an analysis of appeals to authority in terms of relevance can be a useful tool to establish fallaciousness or legitimacy of such a kind of argument even within the established paradigm of argumentation theory.

description: We aim to study the structure of the nebula around the post-AGB, binary star 89 Her. The presence of a rotating disk around this star had been proposed but not been yet confirmed by observations. We present high-resolution PdBI maps of CO J=2-1 and 1-0. Properties of the nebula are directly derived from the data and model fitting. We also present N-band interferometric data on the extent of the hot dust emission, obtained with the VLTI. Two nebular components are found: (a) an extended hour-glass-like structure, with expansion velocities of about 7 km/s and a total mass ~ 3 10$^{-3}$ Mo, and (b) an unresolved very compact component, smaller than ~ 0.4" and with a low total velocity dispersion of ~ 5 km/s. We cannot determine the velocity field in the compact component, but we argue that it can hardly be in expansion, since his would require too recent and too sudden an ejection of mass. On the other hand, assuming that this component is a keplerian disk, we derive disk properties that are compatible with expectations for such a structure; in particular, the size of the rotating gas disk should be very similar to the extent of the hot dust component from our VLTI data. Assuming that the equator of the extended nebula coincides with the binary orbital plane, we provide new results on the companion star mass and orbit.

description: A signification fraction of Galactic massive stars (> 8Mo) are ejected from their parent cluster and supersonically sail away through the interstellar medium (ISM). The winds of these fast-moving stars blow asymmetric bubbles thus creating a circumstellar environment in which stars eventually die with a supernova explosion. The morphology of the resulting remnant is largely governed by the circumstellar medium of the defunct progenitor star. In this paper, we present 2D magneto-hydrodynamical simulations investigating the effect of the ISM magnetic field on the shape of the supernova remnants of a 35Mo star evolving through a Wolf-Rayet phase and running with velocity 20 and 40 km/s, respectively. A 7 microG ambient magnetic field is sufficient to modify the properties of the expanding supernova shock front and in particular to prevent the formation of filamentary structures. Prior to the supernova explosion, the compressed magnetic field in the circumstellar medium stabilises the wind/ISM contact discontinuity in the tail of the wind bubble. A consequence is a reduced mixing efficiency of ejecta and wind materials in the inner region of the remnant, where the supernova shock wave propagates. Radiative transfer calculations for synchrotron emission reveal that the non-thermal radio emission has characteristic features reflecting the asymmetry of exiled core-collapse supernova remnants from Wolf-Rayet progenitors. Our models are qualitatively consistent with the radio appearance of several remnants of high-mass progenitors, namely the bilateral G296.5+10.0 and the shell-type remnants CTB109 and Kes 17, respectively.

description: The main aim of this thesis is to develop the relationship between the harmonic mapping problem between Riemannian surfaces and the one-soliton solution of the elliptic Sinh-Gordon equation. This relation can be achieved with the use of the Jacobi elliptic functions which properties are described. In this thesis we are mainly interested in solving the harmonic mapping problem between Hyperbolic Riemann surfaces. Two examples are studied. The first one is about harmonic map from the upper half plane to itself. In this one we describe a solution and prove one property about continuity. The second one is about the work of Shi, Tam and Wan who described a harmonic map from the infinity strip to itself. In this thesis we find an analytic expression of the solutions by using the Jacobi elliptic functions.

Η σύνδεση αυτή γίνεται με την βοήθεια των ελλειπτικών συναρτήσεων των οποίων οι βασικές ιδιότητες περιγράφονται στην εργασία. Ιδιαίτερη έμφαση δόθηκε στην περίπτωση των αρμονικών απεικονίσεων μεταξύ επιφανειών Ρίμαν με αρνητική σταθερή καμπυλότητα. Μελετήθηκαν εκτενέστερα δύο παραδείγματα. Το πρώτο αφορά αρμονικές απεικονίσεις από το άνω ημιεπίπεδο στον εαυτού του όπου βρίσκουμε μια αρμονική απεικόνιση και ελέγχουμε κάποιες ιδιότητές της. Το δεύτερο στηρίζεται στην εργασία των Shi, Tam και Wan και την εύρεση αρμονικών απεικονίσεων μεταξύ της άπειρης ταινίας και του εαυτού της. Στην παρούσα εργασία βρίσκουμε αναλυτική λύση του προβλήματος με την χρήση των ελλειπτικών συναρτήσεων.

Refuge : exploring the co-operative housing experience of single-mothers
Creators: name: Nelmes, Sandra Kathleen
Publisher: name: University of British Columbia
Year: 2009

description: This study examined the views of eight single-mothers concerning their living experiences in the Four Sisters Housing Co-operative. Such knowledge concerning the views of single-mothers as primary housing consumers was thought to be essential for creating housing forms which serve their particular needs. Since there is a paucity of empirical data concerning the desiderata of co-operative housing for single-mothers, this study employed an exploratory and specifically, qualitative design. In depth, open ended interviews were conducted using a general interview guide approach. The interviews were audio-taped and varied in duration from three to four hours. The process of data analysis was guided by the techniques and procedures of the Grounded Theory approach. Four main categories were identified: (1) Pre-Co-op Housing Problems (2) Security of Housing (3) Supportive Community (4) Opportunities For Personal Development. The central theme of the study was the sense of refuge experienced by single-mothers living in the Four Sisters Housing Co-operative.
