description: Fairtrade-Siegel sollen die Einkommen und Lebensbedingungen von ProduzentInnen erhöhen und so zu mehr Gerechtigkeit im internationalen Handel führen. Ökonomische Überlegungen und empirische Untersuchungen zeigen jedoch, dass dieses Ziel bei Kaffee nur eingeschränkt erreicht wird: Das Fairtrade-Siegel führt bestenfalls zu geringen Einkommenserhöhungen für die Kaffeebäuerinnen und -bauern. Auch hinsichtlich der Vorteile durch geringere Einkommensschwankungen, Zahlungen, die an die Umsetzung sozialer Projekte gebunden sind, sowie einem besseren Zugang zu Krediten sind die Ergebnisse gemischt. Für die Röstereien und Einzelhandelsunternehmen ist Fairtrade ein weiteres Mittel zur Marktsegmentierung.

On the Complexity of the Monte Carlo Method for Incremental PageRank
Creators: name: Lofgren, Peter
Publisher: name: arXiv
Year: 2012
Subjects: subject: Data Structures and Algorithms (cs.DS)
subject: FOS: Computer and information sciences

description: This note extends the analysis of incremental PageRank in [B. Bahmani, A. Chowdhury, and A. Goel. Fast Incremental and Personalized PageRank. VLDB 2011]. In that work, the authors prove a running time of $O(\frac{nR}{ε^2} \ln(m))$ to keep PageRank updated over $m$ edge arrivals in a graph with $n$ nodes when the algorithm stores $R$ random walks per node and the PageRank teleport probability is $ε$. To prove this running time, they assume that edges arrive in a random order, and leave it to future work to extend their running time guarantees to adversarial edge arrival. In this note, we show that the random edge order assumption is necessary by exhibiting a graph and adversarial edge arrival order in which the running time is $Ω\left(R n m^{\lg{\frac{3}{2}(1-ε)}}\right)$. More generally, for any integer $d \geq 2$, we construct a graph and adversarial edge order in which the running time is $Ω\left(R n m^{\log_d(H_d (1-ε))}\right)$, where $H_d$ is the $d$th harmonic number.
Analysis of tooth replacement in adult leopard geckos
Creators: name: Holmes, Scott
Publisher: name: University of British Columbia
Year: 2013

description: Though most dentate vertebrates replace their teeth at least once in the course of their lives, the process of tooth replacement is poorly understood. This is mainly because the major tooth development model is the mouse which only has one generation of teeth. Our previous work suggested that tooth renewal in geckos might involve dental epithelial stem cells and that these putative stem cells become transit- amplifying cells when exposed to canonical WNTs. Here we further investigate this idea using adult leopard geckos (Eublepharis macularius). To further previous findings from our lab that the dental apparatus is a WNT responsive tissue we perturbed the WNT pathway by agonist and antagonist organ cultures of oral tissue explants. BIO stimulated proliferation at an intermediate concentration of 20 μM but not at higher or lower concentrations. This suggests that in vivo, cells are responding to gradients of WNT activity. We also looked at associated BMP and FGF pathways via in situ histology and organ culture manipulation respectively and found alternating patterns of gene expression. We then mapped areas of high canonical WNT signaling and found that nuclear staining for phospho beta catenin was principally found in the outer enamel epithelium and successional lamina. We moved to an in vivo strategy to allow for better tissue survival. Palatal injections of LiCl or the control reagent NaCl were delivered to the base of the maxillary teeth. We found that LiCl increased proliferation in the successional lamina and cervical loops, areas that normally have higher proliferation. We conclude that certain regions of the dental epithelium are sensitive to change in canonical WNT signaling and that this signaling is potentially kept to a localized region via BMP inhibition of the WNT pathway. Regions of the dental lamina that contain putative stem cells may require signals in addition to WNTs to stimulate the formation of transit amplifying cells. Future work will further elucidate the many signaling cascades required for tooth succession to occur.

description: Die Berliner Wirtschaft hat sich in den vergangenen Jahren dynamisch entwickelt, die Industrie hat an diesem Wachstum aber kaum partizipiert. Das Engagement großer Industrieunternehmen lief zuletzt eher darauf hinaus, die Potentiale Berlins für die Entwicklung neuer Geschäftsmodelle und Dienstleistungen zu nutzen. In einer Online-Befragung berichten 76 Prozent, dass in ihrem Berliner Betrieb über die Verlagerung von Tätigkeiten weg von Berlin diskutiert wird. Nach Berlin werden eher nicht-industrielle Bereiche wie Forschung & Entwicklung verlegt oder neue Organisationseinheiten wie Inkubatoren und Digital Labs gegründet. Demgegenüber hat sich die industrielle Produktion in der Stadt nur verhalten entwickelt. Geschätzt wird an Berlin vor allem die Nähe zu Technologiegebern. Allerdings profitieren davon die zahlreichen kleinen Betriebe noch wenig. Um die Industrieentwicklung nachhaltig zu fördern, sollte vor allem die Entwicklung bestehender Betriebe – insbesondere auch kleinerer und mittlerer Unternehmen – forciert werden. Vorhandene Förderansätze in Berlin könnten darauf stärker fokussiert werden.

description: Within the framework of boundary conformal field theory, we evaluate the conductance of stable fixed points of junctions of two and three quantum wires with different Luttinger parameters. For two wires, the physical properties are governed by a single effective Luttinger parameters for each of the charge and spin sectors. We present numerical density-matrix-renormalization-group calculations of the conductance of a junction of two chains of interacting spinless fermions with different interaction strengths, obtained using a recently developed method [Phys. Rev. Lett. 105, 226803 (2010)]. The numerical results show very good agreement with the analytical predictions. For three spinless wires, i.e., a Y junction, we analytically determine the full phase diagram, and compute all fixed-point conductances as a function of the three Luttinger parameters.

description: We study the precise phase estimation using squeezed states with photon losses present. Our exact quantum Fisher information calculation shows significant quantum enhancement and thus reveals the benchmark for practical quantum metrology in this noisy scenario. However, we find that the existing parity measurement scheme [P.M. Anisimov et al, Phys. Rev. Lett. 104, 103602 (2010)] behaves worse than even classical cases given very small losses, unless we take an appropriate loss dependent phase shift. Using our formulae, the two optimized aspects including the pre-detection phase shift and the consequent light intensity of a tradeoff strategy for photon resource arrangement can be both calculated. Therefore our result makes it possible to experimentally realize quantum metrology of phase estimation with squeezed states.

description: Most states in the Hilbert space are maximally entangled. This fact has proven useful to investigate - among other things - the foundations of statistical mechanics. Unfortunately, most states in the Hilbert space of a quantum many body system are not physically accessible. We define physical ensembles of states by acting on random factorized states by a circuit of length k of random and independent unitaries with local support. We study the typicality of entanglement by means of the purity of the reduced state. We find that for a time k=O(1) the typical purity obeys the area law. Thus, the upper bounds for area law are actually saturated {\em in average}, with a variance that goes to zero for large systems. Similarly, we prove that by means of local evolution a subsystem of linear dimensions $L$ is typically entangled with a volume law when the time scales with the size of the subsystem. Moreover, we show that for large values of k the reduced state becomes very close to the completely mixed state.

The significance of companion dogs in the everyday lives of their human caregivers
Creators: name: Maharaj, Nandini Sharada
Publisher: name: University of British Columbia
Year: 2013

description: Using a qualitative design, the purpose of the study was to examine how people describe their relationship with their dog and what kinds of things they do that suggest this bond represents a meaningful relationship. Dog owners (N=27) aged 19 years and older were invited to participate in a focus group discussion. Seven groups were conducted. Employing the steps that Krueger and Casey (2009) recommend, a thematic content analysis revealed the presence of 9 themes: Part of the Family, We Do as We’re Told, Dogs Know, Natural Healers, Nothing Like What a Dog Can Do, My Dog Includes Me, I’m the Alpha Dog, Dog People Are a Rare Breed, and Through Their Eyes. These themes are discussed in light of the current research in the field. The findings suggest some implications for counselling research and practice in improving the health and well-being of dog owners and admirers, as well as, some avenues for further exploration.

Integrity of spinal autonomic pathways in sub-acute and chronic spinal cord injuries
Creators: name: Wong, Shirley Candice
Publisher: name: University of British Columbia
Year: 2013

description: The outcome of spinal cord injury (SCI) is still commonly described in terms of motor and sensory function, despite increasing awareness that there is also damage to the autonomic nervous system (ANS). The purpose of this thesis was to examine the integrity of spinal autonomic pathways among individuals with sub-acute and chronic SCI. The selection of appropriate tests to assess autonomic function is challenging since the ANS is complex. Examining reliability and comparability among measures provides a comprehensive understanding of the validity of specific tools. This doctoral thesis is comprised of three separate investigations that focus on determining the integrity of spinal autonomic pathways following SCI. In the first study (Chapter 2), the focus was on the reliability of heart rate variability (HRV), sympathetic skin responses (SSRs) and an orthostatic challenge (sit-up test). Measures of HRV, SSRs and blood pressure changes during the sit-up test were found to be reliable. Additionally, the sit-up test was compared with the gold standard orthostatic challenge (tilt-table test), which revealed that the sit-up test provokes an orthostatic response comparable to the tilt-table test. In the last two studies (Chapters 3 and 4) HRV and changes in blood pressure (BP) during an orthostatic challenge, SSRs and the Valsalva manoeuvre (VM) were used to examine spinal autonomic integrity. The novel focus on integrity of spinal autonomic pathways revealed that it is affected by lesion level, neurologic severity of injury, and time post-injury. As expected based on extensive existing research on cardiovascular autonomic function following SCI, higher lesion levels produced greater cardiovascular impairments. That is, there is greater compromise to spinal autonomic integrity in high-level compared to low-level SCI. However, the association between neurologic and autonomic “completeness” of injury is unclear. Our findings suggest that time post-injury may affect the latter. During the sub-acute stage, autonomic tests revealed cardiovascular changes in patients in a one-month follow-up after admission to a rehabilitation hospital. The exact time course of alterations to integrity is unknown. Not acknowledging change to spinal autonomic integrity is inherently problematic since it is unclear what neurologic severity of injury infers about autonomic dysfunction.
Running Spectral Index and Formation of Primordial Black Hole in Single Field Inflation Models

description: A broad range of single field models of inflation are analyzed in light of all relevant recent cosmological data, checking whether they can lead to the formation of long-lived Primordial Black Holes (PBHs). To that end we calculate the spectral index of the power spectrum of primordial perturbations as well as its first and second derivatives. PBH formation is possible only if the spectral index increases significantly at small scales, i.e. large wave number $k$. Since current data indicate that the first derivative $α_S$ of the spectral index $n_S(k_0)$ is negative at the pivot scale $k_0$, PBH formation is only possible in the presence of a sizable and positive second derivative ("running of the running") $β_S$. Among the three small-field and five large-field models we analyze, only one small-field model, the "running mass" model, allows PBH formation, for a narrow range of parameters. We also note that none of the models we analyze can accord for a large and negative value of $α_S$, which is weakly preferred by current data.

description: We extend previous analyses of fermions on a honeycomb bilayer lattice via weak-coupling renormalization group (RG) methods with extremely short-range and extremely long-range interactions to the case of finite-range interactions. In particular, we consider different types of interactions including screened Coulomb interactions, much like those produced by a point charge placed either above a single infinite conducting plate or exactly halfway between two parallel infinite conducting plates. Our considerations are motivated by the fact that, in some recent experiments on bilayer graphene there is a single gate while in others there are two gates, which can function as the conducting planes and which, we argue, can lead to distinct broken symmetry phases. We map out the phases that the system enters as a function of the range of the interaction. We discover that the system enters an antiferromagnetic phase for short ranges of the interaction and a nematic phase at long ranges, in agreement with previous work. While the antiferromagnetic phase results in a gap in the spectrum, the nematic phase is gapless, splitting the quadratic degeneracy points into two Dirac cones each. We also consider the effects of an applied magnetic field on the system in the antiferromagnetic phase via variational mean field theory. At low fields, we find that the antiferromagnetic order parameter, Delta(B)-Delta(0) \sim B^2. At higher fields, when omega_c > 2*Delta_0, we find that Delta(B)=omega_c/[ln(omega_c/Delta(0))+C], where C=0.67 and omega_c=eB/m^*c. We also determine the energy gap for creating electron-hole excitations in the system, and, at high fields, we find it to be a*omega_c+2*Delta(B), where a is a non-universal, interaction-dependent, constant.

description: Wird das verarbeitende Gewerbe, das seit dem Zweiten Weltkrieg die Städte zugunsten weniger verdichteter Räume verlassen hat, in die Innenstädte zurückgelockt? Dieser Bericht analysiert das industrielle Gründungsgeschehen der Jahre 2012 bis 2016, aus dem sich die Standortpräferenzen neuer Unternehmen erschließen. Die Auswertung zeigt, dass die Gründungintensität in den großen Agglomerationen im Durchschnitt um fast 40 Prozent höher ist als in den übrigen Regionen der Bundesrepublik. Verantwortlich für die Attraktivität der Agglomerationen könnten die Vorteile der räumlichen Nähe zu Forschungseinrichtungen und Kundschaft für die neue (digitale) Industrie sein. Entsprechend werden viele Unternehmen in den Innenstädten gegründet. Um die Wachstumspotentiale in den Städten zu erschließen, müssen daher nicht nur die Zuflüsse von Risikokapital, Wissen und Fachkräften gesichert, sondern auch Flächenengpässe beseitigt werden.

description: Im Kontext der Energiewende stellt sich die Frage, ob elektrische Speicherheizungen einen Beitrag zur verstärkten Nutzung der fluktuierenden Wind- und Solarenergie und zur Emissionsminderung im Raumwärmebereich leisten können. Im Rahmen eines europäischen Forschungsprojekts wurde am DIW Berlin untersucht, welche Effekte sich im deutschen Stromsystem ergeben, falls die bestehenden Nachtspeicherheizungen rund um die Uhr flexibel geladen werden können. Modellrechnungen für das Jahr 2030 zeigen, dass eine moderate Verringerung der Gesamtkosten des Stromsystems möglich ist. Dabei kommt es nur in einem Szenario mit hohem CO2-Preis zu einem zusätzlichen Ausbau erneuerbarer Energien und entsprechenden Emissionsminderungen. Gleichzeitig lässt sich in einem Zielszenario ein Anteil erneuerbarer Energien von 65 Prozent etwas günstiger erreichen. Einer komplementären betriebswirtschaftlichen Analyse zufolge werden tragfähige Geschäftsmodelle dadurch erschwert, dass die Erlöse von äußeren Umständen abhängen, die einzelne Unternehmen nicht beeinflussen können, insbesondere der Variabilität der Strompreise. Insgesamt dürften flexible Speicherheizungen nur eine Nischenrolle bei der weiteren Umsetzung der Energiewende spielen.

description: The topic of my thesis was “The Holy Spirit in the common liturgical experience of the faithful according to the Hymnography of Paraklitiki, Triodio and Pentecostario”. Motivated by a study of the blessed Liturgical professor Ioannis Fountoulis for the Holy Spirit in the liturgical life of the Church and with the guidance of my professor advisor father Nikodemos Skrettas, an attempt was made to project the face of the Holy Spirit through our operational resources. In the first chapter, the Holy Spirit is presented in its hymnographic dimension based on the liturgical books of Paraklitiki, Triodio and Pentecostario. At the same time we note the teaching of the Church about the Intercessory Spirit through the Holy Bible and the works of the Fathers. In the second chapter there is talk about It from the wealth of Orthodox worship. The Ceremoniality of the Spirit is presented in the ancient Liturgies, in the Mysteries of our Church, in the night services as well as in the personal prayerful struggle of the faithful.

description: A Bose-Hubbard model on a dynamical lattice was introduced in previous work as a spin system analogue of emergent geometry and gravity. Graphs with regions of high connectivity in the lattice were identified as candidate analogues of spacetime geometries that contain trapped surfaces. We carry out a detailed study of these systems and show explicitly that the highly connected subgraphs trap matter. We do this by solving the model in the limit of no back-reaction of the matter on the lattice, and for states with certain symmetries that are natural for our problem. We find that in this case the problem reduces to a one-dimensional Hubbard model on a lattice with variable vertex degree and multiple edges between the same two vertices. In addition, we obtain a (discrete) differential equation for the evolution of the probability density of particles which is closed in the classical regime. This is a wave equation in which the vertex degree is related to the local speed of propagation of probability. This allows an interpretation of the probability density of particles similar to that in analogue gravity systems: matter inside this analogue system sees a curved spacetime. We verify our analytic results by numerical simulations. Finally, we analyze the dependence of localization on a gradual, rather than abrupt, fall-off of the vertex degree on the boundary of the highly connected region and find that matter is localized in and around that region.

description: This article studies the limiting behavior of a class of robust population covariance matrix estimators, originally due to Maronna in 1976, in the regime where both the number of available samples and the population size grow large. Using tools from random matrix theory, we prove that, for sample vectors made of independent entries having some moment conditions, the difference between the sample covariance matrix and (a scaled version of) such robust estimator tends to zero in spectral norm, almost surely. This result can be applied to various statistical methods arising from random matrix theory that can be made robust without altering their first order behavior.

description: Σκοπός της διπλωματικής εργασίας ήταν η μελέτη της δογματικής διδασκαλίας του αγίου Συμεών του Νέου Θεολόγου για τον άνθρωπο και τη σωτηρία. Αρχικά αναφέραμε ορισμένα ιστορικά στοιχεία της εποχής κατά την οποία έζησε ο άγιος Συμεών και τον τρόπο που επηρέασε η εποχή αυτή τη θεολογία. Επίσης αναφέραμε σύντομα τη βιογραφία του αγίου Συμεών. Στη συνέχεια παρουσιάσαμε τη διδασκαλία του αγίου για τη δημιουργία του κόσμου και του ανθρώπου, την εξορία των πρωτόπλαστων από τον Παράδεισο και τις συνέπειες που είχε το γεγονός της πτώσεως. Έπειτα αναφερθήκαμε στο πρόσωπο του Χριστού και το γεγονός της Ενανθρώπησης του Θεού Λόγου καθώς και στις συνέπειες της Ενανθρώπησης για τον άνθρωπο. Στη συνέχεια ασχοληθήκαμε με τον τρόπο και τα μέσα σωτηρίας του ανθρώπου και συγκεκριμένα στην καθοδήγηση από πνευματικό πατέρα, στα μυστήρια της Εκκλησίας και στην άσκηση. Κλείνοντας, εξετάσαμε το θέμα της σωτηρίας ως δώρο του Θεού.
description: The aim of the thesis was the study of the dogmatic teaching of Saint Symeon the New Theologian about man and salvation. First we mentioned some historical facts of the era in which Saint Symeon lived and the way this era affected theology. We also briefly mentioned the biography of Saint Symeon. Furthermore, we presented the teaching of the saint about the creation of the world and man, the exile of the first-born from Heaven and the consequences of the fall. Then we referred to Christ and the fact of the Incarnation of the Word of God as well as the consequences of the Incarnation for man. We also examined the way and means of man's salvation, specifically the guidance from a spiritual father, the mysteries of the Church and practice (askisis). Finally we examined the subject of salvation as a gift from God.

description: Die Regulierung der Wohnmietmärkte ist aus dem täglichen Leben nicht mehr wegzudenken, in Deutschland wie auch in fast allen übrigen Ländern. Die Verwerfungen an den Immobilienmärkten im vergangenen Jahrzehnt haben die gesellschaftlichen Debatten hierzu befeuert. Mieterbewegungen weltweit fordern eine Verschärfung der Regulierung und führen die Bezahlbarkeit von Wohnraum als ein zentrales Bürgerrecht ins Feld. Regulierungsskeptiker fürchten hingegen die Beeinträchtigung der Marktmechanismen durch überbordende Regulierung. Wissenschaftliche Analysen zu dieser Thematik scheiterten bislang häufig an einer unzureichenden Datenbasis. Die vorliegende Studie nimmt sich dieser Problematik an und präsentiert einen einmaligen Datensatz, über den sich die Regulierung der Mietmärkte quantitativ abbilden lässt. Die Indizes zur Messung der Regulierungsintensität liegen für 64 Länder vor und reichen mehr als 100 Jahre zurück. Der im Internet frei verfügbare Datensatz bietet damit die Möglichkeit, die Regulierungsintensitäten und -regime ländervergleichend zu untersuchen. So zeigt sich etwa, dass Deutschland im europäischen Vergleich eine relativ intensive Mietpreiskontrolle hat, die seit 2015 noch verschärft wurde. Die Auswirkungen dieser Verschärfung sollten in Zukunft durch weitere Analysen begleitet werden.

Dynamical heterogeneities in a two dimensional driven glassy model: current fluctuations and finite size effects

description: In this article, we demonstrate that in a transport model of particles with kinetic constraints, long-lived spatial structures are responsible for the blocking dynamics and the decrease of the current at strong driving field. Coexistence between mobile and blocked regions can be anticipated by a first-order transition in the large deviation function for the current. By a study of the system under confinement, we are able to study finite-size effects and extract a typical length between mobile regions.

A Radio-Selected Sample of Gamma Ray Burst Afterglows

description: We present a catalog of radio afterglow observations of gamma-ray bursts (GRBs) over a 14 year period from 1997 to 2011. Our sample of 304 afterglows consists of 2995 flux density measurements (including upper limits) at frequencies between 0.6 GHz and 660 GHz, with the majority of data taken at 8.5 GHz frequency band (1539 measurements). We use this dataset to carry out a statistical analysis of the radio-selected sample. The detection rate of radio afterglows has stayed unchanged almost at 31% before and after the launch of the {\em Swift} satellite. The canonical long-duration GRB radio light curve at 8.5 GHz peaks at 3-6 days in the source rest frame, with a median peak luminosity of $10^{31}$ erg s$^{-1}$ Hz$^{-1}$. The peak radio luminosities for short-hard bursts, X-ray flashes and the supernova-GRB classes are an order of magnitude or more fainter than this value. There are clear relationships between the detectability of a radio afterglow and the fluence or energy of a GRB, and the X-ray or optical brightness of the afterglow. However, we find few significant correlations between these same GRB and afterglow properties and the peak radio flux density. We also produce synthetic light curves at centimeter (cm) and millimeter (mm) bands using a range of blastwave and microphysics parameters derived from multiwavelength afterglow modeling, and we use them to compare to the radio sample. Finding agreement, we extrapolate this behavior to predict the cm and mm behavior of GRBs observed by the Expanded Very Large Array and the Atacama Large Millimeter Array.
