description: Globular Clusters (GCs) are now well known to almost universally show multiple popu-lations (MPs). The HST UV Legacy Survey of a large number of Galactic GCs in UV filters optimized to explore MPs finds that a small fraction of GCs, termed Type II, also display more complex, anomalous behavior. Several well-studied Type II GCs show intrinsic Fe abundance variations, suggesting that the other, less well-studied, Type II GCs should also exhibit similar behavior. Our aim is to perform the first detailed metallicity analysis of NGC 1261, an intermediate mass Type II GC, in order to determine if this object shows an intrinsic Fe variation. We determined the Fe abundance in eight red giant members using Magellan-MIKE and UVES-FLAMES high-resolution, high S/N spectroscopy. The full range of [Fe/H] for the entire sample from the spectra is from -1.05 to -1.43 dexwith an observed spread sigma_obs=0.133 dex. Compared with the total internal error of Sigma_tot=0.06,this indicates a significant intrinsic metallicity spread of Sigma_int=0.119 dex. We found a very similar variation in [Fe/H] using an independent method to derive the atmospheric parameters based on near-IR photometry. More importantly, the mean metallicity of the five presumed normal metallicity stars is -1.37+/-0.02, while that of the three presumed anomalous/highmetallicity stars is -1.18+/-0.09. This difference is significant at the $\pm$2.4Sigma level. We find indications from existing data of other Type II GCs that several of them presumedto have real metallicity spreads may in fact posses none. The minimum mass required for a GC to acquire an intrinsic Fe spread appears to be $\pm$10^5 Msun. We find no strong correlation betwee nmass and metallicity variation for Type II GCs. The metallicity spread is also independent of the fraction of anomalous stars within the Type II GCs and of GC origin.

Γίνεται μια ευρύτερη έρευνα για τις ιεραρχικές δομές της μαγικής απασχόλησης στη μυθιστοριογραφία φαντασίας, όπου η μαγεία που οι γυναίκες εξασκούν θωρείτε συχνά κατώτερη και καταστρεπτική, σε μια προσπάθεια να γίνει κατανοητή η δημοφιλής εικόνα της «κακίας μάγισσας.» Επιπλέον, αυτή η διατριβή εξετάζει και τον τρόπο με τον οποίο ο Τέρι Πράτσετ προκαλεί την παραδοσιακή απεικόνιση των μαγισσών και των μάγων στη μυθιστοριογραφία του και το βαθμό στο οποίο ο ίδιος υπονομεύει και ανατρέπει τις προϋπάρχουσες έννοιες τις μαγικής αρχής. Τέλος, διερευνάται η πολυπλοκότητα της γυναικείας μαγείας στο Δισκόκοσμο σε σχέση με τα θέματα της εξουσίας, της νοικοκυροσύνης ή οικογενειακής ζωής και της ηθικής της φροντίδας.
description: The aim of this project is to explore the manner in which magically gifted women and men have been represented within the canon of Western fantasy literature. A broader investigation of the hierarchical structures of magical employment in fantasy fiction, whereby female magic is often considered inferior and detrimental, is made in an effort to understand the popular image of the “wicked witch.” Furthermore, this thesis examines both the manner in which Terry Pratchett challenges the traditional depiction of witches and wizards in his fiction and the degree to which he subverts pre-existing notions of magical authority. Finally, the complexities of witchcraft on the Discworld are explored in relation to questions of power, domesticity and ethics of care.

description: What if only a light Higgs boson is discovered at the CERN LHC? Conventional wisdom tells us that the scattering of longitudinal weak gauge bosons would not grow strong at high energies. We show that this is not always true. In some composite models, two-Higgs-doublet models, or even supersymmetric models, the presence of a light Higgs boson does not guarantee the complete unitarization of the $WW$ scattering. After the partial unitarization by the light Higgs boson, the $WW$ scattering becomes strongly interacting until it hits one or more heavier Higgs bosons or other strong dynamics. We analyze how the LHC experiments can reveal this interesting possibility of partially strong $WW$ scattering.

description: We show that f(R)-gravity can, in general, give rise to cosmological viable models compatible with a matter-dominated epoch evolving into a late accelerated phase. We discuss the various representations of f(R)-gravity as an ideal fluid or a scalar-tensor gravity theory, taking into account conformal transformations. We point out that mathematical equivalence does not correspond, in several cases, to the physical equivalence of Jordan frame and Einstein frame. Finally, we show that wide classes of f(R)-gravity models, including matter and accelerated phases, can be phenomenologically reconstructed by means of observational data. In principle, any popular quintessence models could be "reframed" as an f(R)-gravity model.

description: We study a system of two symmetrical capacitively coupled quantum dots, each coupled to its own metallic lead, focusing on its evolution as a function of the gate voltage applied to each dot. Using the numerical renormalization group and poor man's scaling techniques, the low-energy Kondo scale of the model is shown to vary significantly with the gate voltage, being exponentially small when spin and pseudospin degrees of freedom dominate; but increasing to much larger values when the gate voltage is tuned close to the edges of the Coulomb blockade staircase where low-energy charge-fluctuations also enter, leading thereby to correlated electron physics on energy/temperature scales more accessible to experiment. This range of behaviour is also shown to be manifest strongly in single-particle dynamics and electron transport through each dot.

description: PTSD is one of the consequences of exposure to war. Due to stressful events in war, veterans may face mental health problems which seriously affects the quality of their lives, families and communities. So, consequently reducing stress and improving the health and quality of the life of veterans and the society is very important. The goal of the present research was to investigate the conceptual and practical principles in designing healing gardens for veterans with PTSD by focusing on reducing stress. This research is a narrative review study based on investigating the theoretical foundations, reviewing test results and the case studies which have been conducted throughout the world. Using healing gardens for veterans, has a positive effect on their health by reducing blood pressure, heart rate, stress, depression and so on. The most effective use of healing gardens for veterans is when the design of the garden is based on stress reduction. In this context, the use of the stress-reduction theory Ulrich and Kaplan is extremely efficient.
The forest for the tree : the Pacific Northwest lumber industry and environmental legislation, 1965-1976
Creators: name: Heard, Carrie Harbin Parnie
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the response of the Pacific Northwest lumber industry to the environmental movement of the 1960s and 1970s and to the legislation the movement inspired. The economic fortunes of the Pacific Northwest have been tied to the lumber industry from the time the region was settled. Until the mid-1960s the lumber industry enjoyed unrivalled influence on policies affecting logging practices on public and private lands. The environmental movement was a strong and unexpected opposition to the industry and its practices. However, the lumber industry mistook changes in the political climate for nothing more than negative public opinion. It was on this problem that the industry repeatedly concentrated, which gave the environmentalists a number of advantages in the political arena. The result was environmental legislation passed at the state and federal levels. The industry was able to begin swinging the pendulum of political influence back to its side when the United States' economy entered a recession in the early 1970s. Armed with figures on inflation and unemployment the lumber industry attempted to convince Congress and the public that environmental regulation and prosperity were not compatible. Although the industry was never again caught off guard as it was by the environmentalists in the 1960s, it never regained the level of political influence that it had prior to that decade. While this thesis concentrates on the general trends of the lumber industry response to events in the late 19 60s and early 1970s, the background of the industry and the climate which gave rise to the environmental movement have also been examined.

description: Reproducibility is a confused terminology. In this paper, I take a fundamental view on reproducibility rooted in the scientific method. The scientific method is analysed and characterized in order to develop the terminology required to define reproducibility. Furthermore, the literature on reproducibility and replication is surveyed, and experiments are modelled as tasks and problem solving methods. Machine learning is used to exemplify the described approach. Based on the analysis, reproducibility is defined and three different degrees of reproducibility as well as four types of reproducibility are specified.This article is part of the theme issue ‘Reliability and Reproducibility in Computational Science: implementing verification, validation and uncertainty quantification in silico’.

description: The main aim of the present work is to study and analyze a reaction-diffusion fractional version of the SIR epidemic mathematical model by means of the non-local and non-singular ABC fractional derivative operator with complete memory effects. Existence and uniqueness of solution for the proposed fractional model is proved. Existence of an optimal control is also established. Then, necessary optimality conditions are derived. As a consequence, a characterization of the optimal control is given. Lastly, numerical results are given with the aim to show the effectiveness of the proposed control strategy, which provides significant results using the AB fractional derivative operator in the Caputo sense, comparing it with the classical integer one. The results show the importance of choosing very well the fractional characterization of the order of the operators.

description: This MSc thesis studies the formation of Germanium Selenide (GeSe) from first principles. In the theoretical part, the first chapter presents the formation of graphene and its most important properties as a new two-dimensional material. More specifically, answering various questions such us, how it was discovered, what it is, what properties it has, how it is produced and what its structure is. The remarkable properties of graphene stood reason for our involvement in the two-dimensional GeSe. That’s why synthesis and formation methods of GeSe nanostructures are described in the second chapter which is a first introduction to GeSe. In the experimental section (third chapter), we are using the program ABINIT to calculate the total energy, the cohesive energy and the energy gap for different molecules and crystals composed of Germanium and Selenium. The aim of this thesis is to find a more stable structure for the molecules and crystals that were selected to be studied.

description: Given a moduli problem with a nice coarse moduli space, which is the most intrinsic and natural divisor on this moduli space? We describe a general method of constructing effective divisors on a large class of moduli spaces using the syzygies of the parametrized objects. In this paper we treat the case of the moduli space of curves and we compute the slope of a doubly infinite sequence of Koszul divisors on M_g. We present a single formula which apart from giving myriads of new counterexamples to the Harris-Morrison Slope Conjecture it also encodes virtually all interesting divisor class calculations on M_g. In particular our formula specializes to earlier results due to Harris-Mumford (the case of the Brill-Noether divisors), Eisenbud-Harris (Giseker-Petri divisors), Khosla as well as to our earlier counterexamples to the Slope Conjecture obtained using K3 surfaces and Hurwitz schemes. We also describe five ways of constructing Koszul divisors on moduli spaces of pointed curves. As an application, we improve most of Logan's results on the Kodaira type of M_{g,n}.

description: Qubits based on crystal defect centers have been shown to exhibit long spin coherence times, up to seconds at room temperature. However, they are typically characterized by a comparatively slow initialization timescale. Here, fluorine implantation into ZnSe epilayers is used to induce defect states that are identified as zinc vacancies. We study the carrier spin relaxation in these samples using various pump-probe measurement methods, assessing phenomena such as resonant spin amplification, polarization recovery, and spin inertia in transverse or longitudinal magnetic field. The spin dynamics in isotopically natural ZnSe show a significant influence of the nuclear spin bath. Removing this source of relaxation by using isotopic purification, we isolate the anisotropic exchange interaction as the main spin dephasing mechanism and find spin coherence times of 100 ns at room temperature, with the possibility of fast optical access on the picosecond time scales through excitonic transitions of ZnSe.

description: Certain semigroups are known to admit a `strong semilattice decomposition' into simpler pieces. We introduce a class of Banach algebras that generalise the $\ell^1$-convolution algebras of such semigroups, and obtain a disintegration theorem for their simplicial homology. Using this we show that for any Clifford semigroup $S$ of amenable groups, $\lp{1}(S)$ is simplicially trivial: this generalises results in \cite{YC_GMJ}. Some other applications are presented.

description: Aims: We searched for the molecular outflows from fifteen molecular clouds associated with ultra-compact and compact HII (UCHII/HII) regions and discussed possible gas heating mechanism. Methods: Mapping observations of CO $J=3-2$ and $J=2-1$ lines were carried out with the KOSMA 3m-Telescope towards the 15 HII regions/molecular cloud complexes. Results: Ten molecular outflows were identified out of the fifteen HII region/molecular cloud complexes. The higher outflow detection rate (67%) suggested that such outflows are as common in high mass star forming regions as those in low mass star forming regions, which is consistent with the results of other authors. The observations also showed that the outflow might occur in the HII region. The integrated CO line intensity ratios (${\rm R_{I_{CO(3-2)}/I_{CO(2-1)}}}$) were determined from the core component of the spectra as well as from both the blue and red wings. Maximum line intensity ratios from the wings and core components appeared to be related to the mid-infrared sources imaged by Midcourse Space Experiment (MSX). The relationship between the maximum line intensity ratios and MSX sources indicates that the molecular gas could be heated by the emission of dust associated with massive stars. Based on maser observations reported in the literature, we found that ${\rm H_{2}O}$ masers were only detected in seven regions. The ${\rm H_{2}O}$ masers in these regions are located near the MSX sources and within the maximum line intensity ratio regions, suggesting that ${\rm H_{2}O}$ masers occur in relatively warm environments.

Assigning a failing grade to a student in the final clinical semester

Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to explore the perceptions and feelings of nurse educators on assigning a failing grade to students enroled in the final semester in a diploma nursing program. Using phenomenological methodology, and Lazarus's process-oriente theoretical framework, nine informants employed in British Columbia Lower Mainland diploma nursing programs were interviewed and audio-taped. Data analysis sought to identify the existence of the phenomena and describe the essence of the experience. The findings of the study illustrate that assigning a failing grade in the final clinical semester is a stressful event for nurse educators. The prominent overriding theme which emerged from the data was stress. Two other interrel ated themes, uncertainty and isolation, were also embedded in the informants' descriptions of their experiences. These themes were stressors in themselves. Nurse educators described immediate and long-term effects of living through their experiences. Immediate effects included being more on guard, as well as modifying and refining their approach to clinical evaluation. The long-term effects resulted in these nurse educators being quite significantly affected by events. They could vividly recall the details of their experiences which left them with lasting impressions. These experiences served as points of reference for nurse educators when faced with other students having similar problems. Three major conclusions were identified. First, assigning a failing grade to a student is stressful. Informants described the experience as more stressful when the student lacked insight. Second, nurse educators expressed a need for emotional support from their peers. They reported feeling isolated and unsupported. They were acutely aware of the potential ramifications of assigning or not assigning a failing grade. This created an element of uncertainty that affected their decision-making ability. Third, the nurse educators believed that program administrators could and should have been more supportive in two major areas: 1) acknowledgement and reassurance and 2) consistent administration of educational policies.

description: Gamma-ray burst (GRB) afterglow observations have allowed us to significantly constrain the engines producing these energetic explosions. Te redshift and position information provided by these afterglows have already allowed us to limit the progenitors of GRBs to only a few models. The afterglows may also provide another observation that can place further constraints on the GRB progenitor: measurements telling us about the environments surrounding GRBs. Current analyses of GRB afterglows suggest that roughly half of long-duration gamma-ray bursts occur in surroundings with density profiles that are uniform. We study the constraints placed by this observation on both the classic ``collapsar'' massive star progenitor and its relative, the ``helium-merger'' progenitor. We study several aspects of wind mass-loss and find that our modifications to the standard Wolf-Rayet mass-loss paradigm are not sufficient to produce constant density profiles. Although this does not rule out the standard ``collapsar'' progenitor, it does suggest a deficiency with this model. We then focus on the He-merger models and find that such progenitors can fit this particular constraint well. We show how detailed observations can not only determine the correct progenitor for GRBs, but also allow us to study binary evolution physics.

The advances in trapping, cooling and tuning the interparticle interactions in these cold atom systems lead to an unprecedented amount of control that one can exert over them. This work aims to show that knowledge acquired studying cold atom systems can be applied to other fields that share similarities and analogies with them, provided that the differences are also known and taken into account. We focus on two specific fields, nuclear physics and statistical optics. The nuclear physics discussion occurs with the BCS-BEC crossover in mind, in which we compare cold Fermi gases with nuclear and neutron matter and nuclei. We connect BECs and atom lasers through both systems' matter-wave character for the analogy with statistical optics. Finally, we present some challenges that, if solved, would increase our understanding of cold atom systems and, thus, the related areas.

description: Οι εξισώσεις του Freundlich και Lamgmuir περιγράφουν ικανοποιητικά το φαινόμενο της προσρόφησης - εκρόφησης Cu, Ni και Pb στο έδαφος της Μεσήμβριας, ενώ για το έδαφος της Γαλάτιτσας μόνο η εξίσωση Langmuir περιγράφει ικανοποιητικά το φαινόμενο. Ο συντελεστής Kd μπορεί να περιγράψει το φαινόμενο της προσρόφησης Cu, Ni και Pb και στα δύο εδάφη. Η οργανική ουσία, τα ορυκτά της αργίλου, η συγκέντρωση του P, η ΙΑΚ και η περιεκτικότητα Mn στο έδαφος καθορίζουν την προσρόφηση και εκρόφηση των Cu, Ni και Pb στα εδάφη αυτά. Στο έδαφος της Μεσήμβριας η προσρόφηση ακολουθεί την σειρά Pb > Cu > Ni ενώ η εκρόφηση των σειρά Cu > Ni > Pb. Στο έδαφος της Γαλάτιστας η προσρόφηση ακολουθεί την σειρά Ni > Pb > Cu και η εκρόφηση την σειρά Cu > Pb > Ni. Η παρουσία Cu στην ταυτόχρονη προσρόφηση – εκρόφηση Cu, Ni και Pb ελαττώνει την προσρόφηση-εκρόφηση του Ni και Pb στα εδάφη αυτά.
description: The phenomenons of adsorption – desorption of Cu, Ni and Pb, in the soil of Mesimvria, were described satisfactory by the Freundlich and Lamgmuir equations. In the case of the Galatista's soil, the phenomenons were described satisfactory only by the Langmuir equation. The Kd coefficient can describe the phenomenon of adsorption of Cu, Ni and Pb, in these soils. Moreover, the adsorption and the desorption of Cu, Ni and Pb in these soils are determined by the organic matter, the clay's minerals, the P concentration, the CEC, and the soil's content in Mn. In the soil of Mesimvria the adsorption followed the order Pb > Cu > Ni, while the desorption followed the order Cu > Ni > Pb. In the soil of Galatista the adsorption followed the order Ni > Pb > Cu and the desorption the order Cu > Pb > Ni. The presence of Cu during the simultaneous adsorption - desorption of Cu, Ni and Pb reduced the adsorption-desorption of the Ni and the Pb, in these soils.

Supermassive recoil velocities for binary black-hole mergers with antialigned spins

description: Recent calculations of the recoil velocity in binary black hole mergers have found the kick velocity to be of the order of a few hundred km/s in the case of non-spinning binaries and about $500 $km/s in the case of spinning configurations, and have lead to predictions of a maximum kick of up to $1300 $km/s. We test these predictions and demonstrate that kick velocities of at least $2500 $km/s are possible for equal-mass binaries with anti-aligned spins in the orbital plane. Kicks of that magnitude are likely to have significant repercussions for models of black-hole formation, the population of intergalactic black holes and the structure of host galaxies.

description: Η παρούσα διατριβή ειδίκευσης ασχολείται με την εφαρμογή σύγχρονων γεωφυσικών μεθόδων στην περιοχή του Χ.Υ.Τ.Α. Σερρών, με σκοπό να ελεγχθεί η στεγανότητα του χώρου άμεσης ταφής, αλλά και η περιοχή κατάντη αυτού καθώς επίσης και περιοχή μελλοντικής κυψέλης. Ο έλεγχος αυτός αφορά την παρουσία πιθανής διαρροής στραγγισμάτων στους γεωλογικούς σχηματισμούς του υπεδάφους και κατ’επέκταση τον εντοπισμό υπόγειων υδάτων που ενδέχεται να απειλούνται από αυτά. Για τον σκοπό αυτό χρησιμοποιήθηκαν στοιχεία της υδρολογικής, γεωτεχνικής και περιβαλλοντικής μελέτης του Χ.Υ.Τ.Α. Σερρών και στοιχεία που προέκυψαν από τις επί τόπου μετρήσεις. Για τις μετρήσεις στον χώρο έγινε χρήση της μεθόδου της ειδικής ηλεκτρικής αντίστασης και ειδικότερα της ηλεκτρικής τομογραφίας, ενώ τα αποτελέσματα της έρευνας έδωσαν μία ικανοποιητική εικόνα της κατάστασης του υπεδάφους στις περιοχές που ερευνήθηκαν.
description: The present thesis deals with the use of current geophysical methods in the area of Space of Sanitary Burial of Litter of Serres city in order to check the leak-tightness beneath and in the vicinity of the burial space. This research concerns the possible event of leachate leakage to the geological formations and further more to locate ground - water which could be threatened by the leachate. For this purpose, data from the hydrological, geotechnical and environmental study of sanitary landfill of Serres city were collected. For the present survey the electrical tomography has been applied. The results of the geophysical investigation gave a satisfactory image concerning the permeability of the topsoil and the near surface geological layers in the area of the active and the future cells of the sanitary landfill.

description: We revisit the 't Hooft expansion of 1/2 BPS circular Wilson loop in N=4 SYM studied by Drukker and Gross in hep-th/0010274. We find an interesting recursion relation which relates different number of holes on the worldsheet. We also argue that we can turn on the string coupling by applying a certain integral transformation to the planar result.

description: We consider an integrable system of reduced Maxwell-Bloch equations that describes the evolution of an electromagnetic field in a two-level medium that is inhomogeneously broadened. We prove that the relevant Backlund transformation preserves the reality of the n-soliton potentials and establish their pole structure with respect to the broadening parameter. The natural phase space of the model is embedded in an infinite dimensional loop algebra. The dynamical equations of the model are associated to an infinite family of higher order Hamiltonian systems that are in involution. We present the Hamiltonian functions and the Poisson brackets between the extended potentials.

Στην έρευνα συμμετείχαν 450 μαθητές/τριες της Α΄ Λυκείου, που χωρίστηκαν στην ομάδα παρέμβασης και στην ομάδα ελέγχου. Η παρέμβαση αφορούσε τη διδασκαλία του μαθήματος Φυσικής Αγωγής του Λυκείου με τη μέθοδο της αυτοδιδασκαλίας και είχε διάρκεια 10 εβδομάδες. Ερωτηματολόγια δόθηκαν πριν και μετά την παρέμβαση. Μετρήθηκαν το κλίμα αυτονομίας, τα κίνητρα, η ευχαρίστηση, η προσπάθεια και η ανία στο μάθημα Φυσικής Αγωγής, τα κίνητρα για εξωσχολική Φυσική Δραστηριότητα, οι στάσεις, ο Αντιλαμβανόμενος Έλεγχος Συμπεριφοράς, η πρόθεση για τις εξωσχολικές Φυσικές Δραστηριότητες. Τα αποτελέσματα από την ανάλυση διακύμανσης με επαναλαμβανόμενες μετρήσεις έδειξαν ότι το πρόγραμμα παρέμβασης στο μάθημα Φυσικής Αγωγής Λυκείου που βασίζεται στη μέθοδο της αυτοδιδασκαλίας, επηρεάζει θετικά το κλίμα αυτονομίας και τα αυτόνομα κίνητρα για εξωσχολική Φυσική Δραστηριότητα καθώς επίσης και την πρόθεση για συμμετοχή σε εξωσχολική Φυσική Δραστηριότητα. Από τα αποτελέσματα προκύπτει ότι η μέθοδος της αυτό-διδασκαλίας μπορεί να αποτελέσει μια αποτελεσματική πρακτική για τη βελτίωση των πεποιθήσεων των μαθητών/τριών για την εξωσχολική φυσική δραστηριότητα.
description: The aim of the present study was to investigate the effect of self-teaching style on senior high school students’ beliefs towards leisure-time physical activity. The sample of the study consisted of 450 students of the first grade of senior high school, assigned into intervention and control groups. The intervention involved teaching physical education lessons with the self-teaching style and lasted 10 weeks. Participants completed just prior and immediately after the intervention a survey including measures of perceptions of autonomy supportive climate, physical education and leisure-time physical activity motivational regulations, enjoyment and boredom in physical education, and attitudes, perceived behavioral control, subjective norms and intentions towards leisure-time physical activity. The results of the analysis of variance with repeated measures revealed a positive effect of the self-teaching style on perceptions of autonomy supportive climate, leisure-time physical activity autonomous motivation and intentions. The study’s findings imply that the self-teaching style may be an effective strategy to promote positive beliefs towards leisure-time physical activity.
