description: Die wachsende Zahl an Menschen, die aus ihren Herkunftsländern fliehen musste und nach 2015 in Berlin ankam, stellte städtische Einrichtungen und die Bereitstellung sozioökonomischer Dienstleistungen für Personen mit diversen soziokulturellem und politischen Hintergründen vor eine große Herausforderung. Es gilt anzunehmen, dass zusätzlich zu früheren traumatischen Erfahrungen, der mehrdimensionale und komplizierte Prozess der Verteilung von Geflüchteten in städtischen Räumen zu Belastungen führen und die Prävalenz psychischer Störungen erhöhen kann. Angesichts der Tatsache, dass geflüchtete Frauen verstärkt unter verschiedenen Formen stressbedingter Störungen leiden, zielt die Dissertation darauf ab, jene sozialen Stressoren in drei verschiedenen sozio-räumlichen Settings zu untersuchen, welchen sich geflüchtete Frauen bei ihrer Ankunft in Berlin ausgesetzt wahrnahmen.
description: The growing number of forcibly displaced people arriving in Berlin after 2015 brought about an extensive challenge in providing urban socio-economic facilities and services for numerous individuals from different socio-cultural and political backgrounds. The multi-dimensional and complicated process of resettlement of refugees in urban spaces, in addition to their earlier traumatic experiences, might result in distress and intensify the prevalence of mental disorders. Considering that refugee women are more likely to suffer from various forms of stress-related disorders, the dissertation aimed to evaluate the perceived social stressors by refugee women in three different socio-spatial settings upon their arrival in Berlin.
Effective city-region governance: a case study of local economic development in Greater Vancouver
Creators: name: Christie, Allison Veronica
Publisher: name: University of British Columbia

description: City-regions have emerged as a critical focus of economic activity, governance and social organization as a result of the ongoing processes of economic restructuring. Canadian city-regions are limited in their capacity to respond to contemporary problems due to the functional and structural limitations of outdated governing systems. The Greater Vancouver Regional District (GVRD) is a system of voluntary cooperation among twenty-one local municipalities. While this model has served the city-region well, its limits have been reached in terms of its ability to deliver necessary region-wide policy responses. Economic development, a crucial policy issue for urban regions, is characterized by vague and ill-functioning relationships and by poorly-defined policies and programs between the member municipalities and the regional tier. The GVRD is constrained by the fact that it can only do what is delegated by its members, and decisions are often compromised in order to suit conflicting local interests that exist throughout the region. A new governing model for the city-region should foster a regional vision, and should be appropriate for the responsibilities the city-region is expected to fulfill in this era of global competition. A single-tier government is the most appropriate model for Greater Vancouver, allowing comprehensive regional planning and innovative economic development to be carried out with a strong regional voice, and for decisions to be made with a greater degree of certainty, preserving the livability and economic health of Canada's fastest-growing city-region.

description: Astrobiology, the study of life as a planetary phenomenon, aims to understand the fundamental nature of life on earth and the possibility of life elsewhere. To achieve this goal, astrobiologists have initiated unprecedented communication between the disciplines of astronomy, biology, chemistry, and geology. The Astrobiology Primer has been created as a reference tool for those who are interested in the interdisciplinary field of astrobiology. The field incorporates many diverse research endeavors, but it is our hope that this slim volume will present the reader with all he or she needs to know to become involved and to understand, at least at a fundamental level, the state of the art. Because of the great diversity of material, each section was written by a different author with a different expertise. The Primer was constructed collaboratively. Ninety researchers from around the world contributed information with regard to what they expected from other astrobiologists and what they would like to know themselves but still had difficulty understanding (see Contributors). Those submissions were read and considered by the Editors who produced a list of seven general categories of knowledge, represented by the seven chapters in the Primer: 1) Stellar Formation and Evolution, 2) Planetary Formation and Evolution, 3) Astrobiogeochemistry and the Origin of Life, 4) Evolution of Life through Time, 5) Planet Detection & Characterization, 6) Diversity of Life, and 7) Science in Space. No one volume, of course, can contain the vast amount of information brought to play in astrobiology, but we believe that the Primer will provide a forum and a language around which the community will have the opportunity to develop a consensus about central issues.

description: We discuss, in the perturbative regime, the scattering of Gaussian pulses of odd-parity gravitational radiation off a non-rotating relativistic star and a Schwarzschild Black Hole. We focus on the excitation of the $w$-modes of the star as a function of the width $b$ of the pulse and we contrast it with the outcome of a Schwarzschild Black Hole of the same mass. For sufficiently narrow values of $b$, the waveforms are dominated by characteristic space-time modes. On the other hand, for sufficiently large values of $b$ the backscattered signal is dominated by the tail of the Regge-Wheeler potential, the quasi-normal modes are not excited and the nature of the central object cannot be established. We view this work as a useful contribution to the comparison between perturbative results and forthcoming $w$-mode 3D-nonlinear numerical simulation.

Exact theory for the Rezzolla-Zhidenko metric and self-consistent calculation of quasinormal modes

description: A covariant, scalar-tensor gravity is constructed such that the static, spherically symmetric Rezzolla-Zhidenko metric is an exact solution to the theory. The equations describing gravitational perturbations of this spacetime, which represents a generic black hole possessing an arbitrary number of hairs, can then be derived. This allows for a self-consistent study of the associated quasinormal modes. It is shown that mode spectra are tied to not only the non-Einstein parameters in the metric but also to those that appear at the level of the action, and that different branches of the exact theory can, in some cases, predict significantly different oscillation frequencies and damping times. For choices which make the theory appear more like general relativity in some precise sense, we find that a nontrivial Rezzolla-Zhidenko parameter space is permissible under current constraints on fundamental ringdown modes observed by Advanced LIGO.

description: Sedimentology,faunistic and radiometric analyses were performed on three bottom cores from the Accademia Cave (Ustica,Southern Tyrrhenian Sea). The two outermost sites (near the cave openings) contain coarses sediments,while the innermost sample (from a sheltered area) consists of noticeably finer sediments.Similarly,differences are present in the benthic thanatocoenoses at these sites. The innermost core is more homogeneous,essentially authochthonous and dominated by "cave species"while the cores near the entrance of the cave are more heterogeneous and contaminated by external bioclasts. These difference indicate a confinement gradient mainly affected by hydrodynamics. Conversely,radiometric data indicate few signs of temporal variations,at least for the last 1,000 years recorded in the sediments studied. A slight topward confinement increase in the innermost core may be related to local changes in cave topography.

Ολοι οι μαθητές εξετάσθηκαν 1) με μια συστοιχία ασκήσεων(Ε.Μ.) οι οποίες έλεγχαν το φωνολογικό κύκλωμα, τον κεντρικό επεξεργαστή και την λεκτική μνήμη(διαχειστική επεισοδίων) και 2) δύο κείμενα τα οποία ήταν διαφορετικής δυσκολίας όσον αφορά την κατανόηση(εύκολο-δύσκολο). Η στατιστική ανάλυση(αναλύσεις διακύμασης και παλινδρόμησης) έδειξε ότι η μουσική εκπαίδευση δε είχε καμία επίδραση στην επίδοση στις ασκήσεις εργ. μνήμης ή στο επίπεδο κατανόησης των κειμένων. Υπήρξε όμως, αλληλεπίδραση της μουσ. εκπαίδευσης με το μουσ. υπόβαθρο.

description: Research on the effects of music training on verbal abilities and text comprehension has come up with contradictory results. The same regards the use of music as background during studying. Our research aimed at investigating the possible interaction of these two factors on text comprehension using tasks differing in difficulty. A 2 (music training) X 2 (music background) design was implemented. Age and gender were also included. The participants were 172 students of both genders, aged 9 – 14. Of them 98 had musical training (M = 3 years). All students were first tested with a working memory test battery (WM). A series of MANCOVAS with WM as covariate were performed on text comprehension performance, on metacognitive experiences (ME) before and after reading the texts, and on text- related positive and negative emotions. The results showed that music training did not have a significant effect on text comprehension but there was an interaction of music training with music background, in favour of the non- trained participants with music background. There were also positive effects of music background on positive affect (joy) and on feeling of difficulty of the difficult text, but not on other ME. There was no effect of WM on ME or affect. Task difficulty had an effect both on text comprehension and ME. Gender but not age had also an effect on feeling of difficulty and interest in favour of girls.

description: The Longarini and Cuba lagoons are the largest westlands in a system of lagoons located inland of the Ambra Coast in southeastern Sicily.A reconstruction of their evolution througt a comparative study of textural, compositional and faunal data, showed facies of a lagoonal system influenced differently and in varying degrees by rivers and sea. The oldest layers are made of lagoonal pelitic sediments containing faunal assemblages (mixed biocenoses) referable to the zonal classification of the paralic environment proposed by Guelorget & Perthuisot (1983). In the more recent layers an environmental change is recorded,showing an increase in lagoonal characteristics and a decrease in "mixed" biocenoses, due to a greater input of solid materials from the adjacent hydrographic basin.

Geometric phases and Bloch sphere constructions for SU(N), with a complete description of SU(4)

Year: 2008
Subjects: subject: Quantum Physics (quant-ph)

description: A two-sphere ("Bloch" or "Poincare") is familiar for describing the dynamics of a spin-1/2 particle or light polarization. Analogous objects are derived for unitary groups larger than SU(2) through an iterative procedure that constructs evolution operators for higher-dimensional SU in terms of lower-dimensional ones. We focus, in particular, on the SU(4) of two qubits which describes all possible logic gates in quantum computation. For a general Hamiltonian of SU(4) with 15 parameters, and for Hamiltonians of its various sub-groups so that fewer parameters suffice, we derive Bloch-like rotation of unit vectors analogous to the one familiar for a single spin in a magnetic field. The unitary evolution of a quantal spin pair is thereby expressed as rotations of real vectors. Correspondingly, the manifolds involved are Bloch two-spheres along with higher dimensional manifolds such as a four-sphere for the SO(5) sub-group and an eight-dimensional Grassmannian manifold for the general SU(4). This latter may also be viewed as two, mutually orthogonal, real six-dimensional unit vectors moving on a five-sphere with an additional phase constraint.

description: Research on image quality assessment (IQA) remains limited mainly due to our incomplete knowledge about human visual perception. Existing IQA algorithms have been designed or trained with insufficient subjective data with a small degree of stimulus variability. This has led to challenges for those algorithms to handle complexity and diversity of real-world digital content. Perceptual evidence from human subjects serves as a grounding for the development of advanced IQA algorithms. It is thus critical to acquire reliable subjective data with controlled perception experiments that faithfully reflect human behavioural responses to distortions in visual signals. In this paper, we present a new study of image quality perception where subjective ratings were collected in a controlled lab environment. We investigate how quality perception is affected by a combination of different categories of images and different types and levels of distortions. The database will be made publicly available to facilitate calibration and validation of IQA algorithms.

description: We introduce an infectious default and recovery model for N obligors. Obligors are assumed to be exchangeable and their states are described by N Bernoulli random variables S_{i} (i=1,...,N). They are expressed by multiplying independent Bernoulli variables X_{i},Y_{ij},Y'_{ij}, and default and recovery infections are described by Y_{ij} and Y'_{ij}. We obtain the default probability function P(k) for k defaults. Taking its continuous limit, we find two nontrivial probability distributions with the reflection symmetry of S_{i} \leftrightarrow 1-S_{i}. Their profiles are singular and oscillating and we understand it theoretically. We also compare P(k) with an implied default distribution function inferred from the quotes of iTraxx-CJ. In order to explain the behavior of the implied distribution, the recovery effect may be necessary.

description: We consider the Newtonian planar three--body problem with positive masses $m_1$, $m_2$, $m_3$. We prove that it does not have an additional first integral meromorphic in the complex neighborhood of the parabolic Lagrangian orbit besides three exceptional cases $ \sum m_i m_j/(\sum m_k)^2= 1/3$, $2^3/3^3$, $2/3^2$ where the linearized equations are shown to be partially integrable. This result completes the non-integrability analysis of the three-body problem started in our previous papers and based of the Morales-Ramis-Ziglin approach.

Η έρευνα ενδείκνυται για ανάπτυξη διαλόγου σε θεωρητικό και πρακτικό επίπεδο ανάμεσα στην Εκπαίδευση για την Αειφόρο Ανάπτυξη και πιο εναλλακτικές και ριζοσπαστικές εκπαιδευτικές προσεγγίσεις, όπως η ελευθεριακή εκπαίδευση.
description: This research aims to explore the relationship between libertarian education and sustainable schools through a case study of the libertarian school 'Tο Mikro Dentro' in Thessaloniki. Initially, theoretical elements concerning the two concepts are presented, with a bibliographical reference to their principles and historical development. Qualitative and quantitative methods are combined in the research. Guided by the 8 pillars of Greek sustainable schools, interviews with 5 teachers from the libertarian school and field observations are conducted. The thematic analysis highlights and documents with examples the points of convergence between libertarian education and sustainable schools, mainly in terms of adherence to democratic processes, school openness to society, holistic education and conservation of natural resources. The research is suitable for developing a dialogue at theoretical and practical level between Education for Sustainable Development and more alternative and radical educational approaches, such as libertarian education.

description: Every software project, no matter the method of the standard that is used, is implemented, so that user requirements are satisfied. In traditional software engineering, there are specific requirement engineering processes which specify system requirements in exact and complete way.Due to time and cost constraints in some cases it is possible and hard to implement all the requirements derived from extraction and analysis process.

description: Massive bosonic fields in the background of a Kerr black hole can either trigger superradiant instabilities (black-hole bombs) or form equilibrium configurations corresponding to pure bound states, known as stationary scalar clouds. Here, similar phenomena are shown to emerge in the fluctuation dynamics of a rotating photon-fluid model. In the presence of suitable vortex flows, the density fluctuations are governed by the massive Klein-Gordon equation on a (2+1) curved spacetime, possessing an ergoregion and an event horizon. We report on superradiant instabilities originating from quasi-bound phonon states trapped by the vortex background and, remarkably, on the existence of stationary modes in synchronous rotation with the horizon. These represent the acoustic counterpart of astrophysical scalar clouds. Our system offers a promising platform for analogue gravity experiments on superradiant instabilities of massive bosons and black-hole-field equilibrium configurations.

Consistent harvesting strategy in salmon aquaculture
Creators: name: Dubreuil, Michel
Publisher: name: University of British Columbia
Year: 2009

description: The goal of this study was to design a consistent harvest strategy using various types of salmon smolts differentiated by species, weight and timing of introduction into seawater. Consistent harvesting is a production strategy leading to the continuous harvest of fresh salmon at a predictable size 52 weeks of the year. The economic and production characteristics of six chinook salmon (Oncorhynchus tschawytscha) and six Atlantic salmon (Salmo salar) cohorts were first analyzed to establish the economic and production factors leading to their respective optimal harvest time and to compare the performance of each cohort. The study was developed with reference to the British Columbia salmon farming industry. To achieve these objectives, a discrete and deterministic bioeconomic model was developed following the theoretical framework proposed by Bjorndal (1988, 1990). A series of sub-models were incorporated to simulate three major components of the biological system. First, fish growth was simulated using a modified Iwama-Tautz growth model to which was added a dampening factor to embody a size/growth relationship. Second, feed requirements was computed using a bioenergetic feeding model based on a formulation empirically derived by Cho (1992) and the work published by Maroni et al (1994) on differential feed conversion efficiencies. Finally, two mortality rate scenarios were specified on the basis of the underlying causes of mortality and the effect of sexual maturation on fish quality and survival. In scenario 1, a fixed mortality rate was relaxed by the convergence of two conditions beyond which the mortality rate began to increase. These conditions were specified as a lower fish weight threshold and a spring to fall timeframe during the year. In scenario 2, the mortality rate was assumed fixed through the production cycle. The results showed that most fish cohort had a comparative advantage in terms of maximizing returns over a specific market window during the year. The major factors determining the comparative advantage of each cohort were life expectancy and growth performance in relation to water temperature. As a result, the optimal harvest timeframe for a cohort selected within a production portfolio could differ from its own optimal harvest time as a single production unit.

description: This volume covers Leg 71 of the cruises of the Drilling Vessel Glomar Challenger. DSDP Leg 71 was the first of five legs designed to study late Mesozoic and Cenozoic paleoenvironments in the South Atlantic Ocean; the broad objectives of Leg 71 were to study the history of sedimentation at the eastern end of the Falkland Plateau, the effect of the plateau as a barrier between water masses during the early opening of the South Atlantic, and the evolution of the Antarctic Convergence. In particular, there were four specific objectives: 1) To expand upon the geologic history of the Falkland Plateau from sediment cores and to assess its influence upon oceanic circulation during the Cenozoic. 2) To study the history of bottom water flow through the region during Cenozoic time on the basis of its erosional, transportational, and depositional consequences, of calcium carbonate dissolution, and of the oxygen isotopic record. 3) To provide Cenozoic biostratigraphic sequences for the South Atlantic. 4) To provide, if coring was successful enough, the Mesozoic sedimentary sequences needed to define the paleoceanographic conditions existing during the early opening and development of the Atlantic Ocean. Five high-priority sites were proposed for Leg 71, but only 4 were drilled (Sites 511-514) between January and February of 1980. Leg 71 began in Valparaiso, Chile and ended in Santos, Brazil.

description: A biosensor is a compact analytical device incorporating a biological or biologically dereved sensing element integrated within or intimately associated with a physicodremical transducer.The usual aim of a biosensor is to produce either discrete or continuous digital electronic signal which are propotional to a single analyte or a related group of analytes. Over the past 20 years, biosensors have revolutionaized the cave and management of diabetes and have had important impacts in several other areas such as : clinical diagnostics and biomedicine, food and drink production, pollution control, pharmacuetical and veterinary analysis. Biosensors are very promising analytical tools as early waning systems. Several recognition protypes are currently being tested but are still very primitive

description: One of the major goals of neutrino astronomy is to explore the otherwise unknown fluxes and interactions of ultrahigh energy neutrinos. The existing neutrino telescopes look at three types of events: particle showers, muons, and taus. In this paper we discuss the dependence of the event rates on the neutrino nucleon cross-sections as we scale the cross sections, with energy, in different scenarios beyond the standard model. Our focus will be on the IceCube detector.

description: The LHC is expected to increase its center-of-mass energy from 13 TeV to 14 TeV for Run 3 scheduled from 2022 to 2024. After Run 3, upgrades for the High-Luminosity-LHC (HL-LHC) programme are planned and the operation will start in 2027, increasing the instantaneous luminosity to 5.0 -- 7.5 times its nominal luminosity. Continuous upgrades of the ATLAS trigger system are planned to cope with the high event rate and to keep the physics acceptance. During the long shutdown period before Run 3, new detectors will be installed to improve the trigger performance. New trigger logic, combining information from detectors located outside of the magnetic field and new detectors installed inside the magnetic field, are introduced from Run 3 to reduce the trigger rate. In order to handle data from the various detectors, a new trigger processor board has been developed and the design is presented. During the upgrade for HL-LHC, the trigger and readout systems of the first level hardware-based part are planned to be upgraded. Full-granularity information will be transferred to the trigger processor board which enables more off-line like track reconstruction in the hardware-based system. To handle the full-granularity information and perform the hardware-based track reconstruction, the trigger processor board will implement an FPGA with hundreds of pairs of transceivers and huge memory resources. Expected performance for the hardware-based endcap muon trigger in Run 3 and HL-LHC will also be presented.

description: Der Beitrag analysiert, wie digitale Plattformen urbanes Arbeiten und Leben ebenso verändern wie die gelebte Räumlichkeit und die materielle Architektur der Stadt. Davon sind nicht nur Arbeitsverhältnisse berührt, sondern auch alltägliche Formen und Praktiken von Mobilität, Konsum oder Reproduktion. Basierend auf umfassenden ethnografischen Forschungen beschreiben wir erstens den Aufstieg der Plattformarbeit in Berlin, insbesondere am Beispiel von Uber, Deliveroo und Helpling. Wir nehmen neue Formen algorithmischer Organisation, Kontrolle und Überwachung von Arbeit im Stadtraum in den Blick und zeigen, dass Plattformarbeit primär migrantisch ist. Davon ausgehend skizzieren wir zweitens die Umrisse eines entstehenden Plattform-Urbanismus. Das umfasst sowohl ein Verständnis der Räume und Geografien digitaler Plattformen als auch eine theoretische Perspektivierung des Begriffs. Drittens betonen wir, dass kritische Analysen des emergenten Plattform-Urbanismus zeigen können, wie Plattformen darauf abzielen, unverzichtbare urbane Infrastrukturen zu werden. Allerdings zeigt sich, dass diese Infrastrukturwerdung urbaner Plattformen kein reibungsloser Prozess ist, sondern politisch und ökonomisch umkämpft.

Ιστορική αφετηρία αποτελεί το εγχείρημα του Καρόλου Ε' να αποκαταστήσει τη θρυμματισμένη από τη λουθηρανική επανάσταση χριστιανοσύνη και να επιβάλλει τον καθολικισμό, και η ανάλογη απόπειρα του γιού του Φίλιππου Β'. Επίσης μελετώνται τα γεγονότα της "Νύχτας του Βαρθολομαίου" στη Γαλλία και διερευνώνται ακόμη ο Τριακονταετής Πόλεμος και η Ενδοξη Επανάσταση στην Αγγλία. Στο φιλοσοφικό μέρος, επιχειρούμε να ανιχνεύσουμε τον αντίκτυπο και τη λειτουργία αυτών των γεγονότων στο φιλοσοφικό στοχασμό του Τζών Λοκ, αναλύοντας συγχρόνως το περιεχόμενο της Επιστολής
description: The year 1517 is a historical starting point. It is the years when Martin Luther breaks the Christian unity with the religious reformation known as "Protestantism". In particular i studied the undertaking of Charles V to re-establish the fragmented christendom and resurrect the roman empire with the stamp of catholicism. What is, also going to be discussed is the relevant attempt of the son of Philip B', as well as the religious conflicts in France, focusing on the events of ST. Bartholomew's Day Massacre. Besides, i studied the Thirty year War and the events of the Glorious Revolution in England, which have a religious content. Furthermore, i detected the role and the impact of all above events on John Locke's meditation analyzing at the same time the content of his Letter/Epistola

description: Delta Gravity is a gravitational model based on an extension of General Relativity given by a new symmetry called $\tildeδ$. In this model, new matter fields are added to the original matter fields, motivated by the additional symmetry. We call them $\tildeδ$ matter fields. This model predicts an accelerating Universe without the need to introduce a cosmological constant. In this work, we study the Delta Gravity prediction about the scalar CMB TT power spectrum using an analytical hydrodynamical approach. To fit the Planck satellite's data with the DG model, we used a Markov Chain Monte Carlo analysis. We also include a study about the compatibility between SNe-Ia and CMB observations in the Delta Gravity Context. Finally, we obtain the scalar CMB TT power spectrum and the fitted parameters needed to explain both SNe-Ia Data and CMB measurements. The results are in a reasonable agreement with both observations considering the analytical approximation. We also discuss if the Hubble Constant and the Accelerating Universe are in concordance with the observational evidence in the Delta Gravity context.

description: A detailed study of the ground state of the Coulomb system $(\al \al e e)$ which corresponds to the $He_2^{2+}$ molecular ion in a magnetic field $B=0-4.414 \times 10^{13} $ G in parallel configuration (infinitely massive $\al-$particles are situated along a magnetic field line) is presented. The variational method is employed using a trial function which includes electronic correlation in the form $\exp{(γr_{12})}$ where $γ$ is a variational parameter. It is shown that the quantum numbers of the lowest total energy state depend on the magnetic field strength. It evolves from the spin-singlet ${}^1\Si_g$ metastable state at $0 \leq B \lesssim 0.85$ a.u. to a repulsive spin-triplet ${}^3\Si_u$ state for $0.85 {a.u.} \lesssim B \lesssim 1100$ a.u. and, finally, to a strongly bound spin-triplet ${}^3Π_u$ state at stronger fields $B \gtrsim 1100$ a.u. The lowest vibrational energy for the latter case is calculated.
