description: We introduce a framework to analyze the conversation between two competing groups of Twitter users, one who believe in the anthropogenic causes of climate change (Believers) and a second who are skeptical (Disbelievers). As a case study, we use Climate Change related tweets during the United Nation's (UN) Climate Change Conference - COP24 (2018), Katowice, Poland. We find that both Disbelievers and Believers talk within their group more than with the other group; this is more so the case for Disbelievers than for Believers. The Disbeliever messages focused more on attacking those personalities that believe in the anthropogenic causes of climate change. On the other hand, Believer messages focused on calls to combat climate change. We find that in both Disbelievers and Believers bot-like accounts were equally active and that unlike Believers, Disbelievers get their news from a concentrated number of news sources.

SU(2)xU(1) non-anticommutative N=2 supersymmetric gauge theory
Creators: name: Ketov, Sergei V.

Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We derive the master function governing the component action of the four-dimensional non-anticommutative (NAC) and fully N=2 supersymmetric gauge field theory with a non-simple gauge group U(2)=SU(2)xU(1). We use a Lorentz singlet NAC-deformation parameter and an N=2 supersymmetric star (Moyal) product which do not break any of the fundamental symmetries of the undeformed N=2 gauge theory. The scalar potential in the NAC-deformed theory is calculated. We also propose the non-abelian BPS-type equations in the case of the NAC-deformed N=2 gauge theory with the SU(2) gauge group, and comment on the SU(3) case too. The NAC-deformed field theories can be thought of as the effective (non-perturbative) N=2 gauge field theories in a certain (scalar only) N=2 supergravity background.

L1 orthography and ESL literacy : a comparison of English, Persian, and Chinese L1 speakers
Creators: name: Low, Pauline B.
Publisher: name: University of British Columbia
Year: 2010

description: Orthographies vary in how sounds are translated to print. Alphabetic orthographies utilize grapheme-phoneme correspondences, whereas nonalphabetic orthographies do not. The present study examined whether learning to read and spell in English as a second language was influenced by the learner's first language. The participants were 122 third-grade children (mean age: 8.88 years) with contrasting linguistic backgrounds. The sample was comprised of 45 children who's native language was English (alphabetic), 32 ESL children who's native language was Persian (alphabetic) and 45 ESL children who's native language was Chinese (nonalphabetic). The performance of the three groups was comparable on measures of reading, phonological awareness, decoding, working memory and spelling. However, the Chinese speakers scored significantly lower than the alphabetic speakers on measures of syntactic awareness and pseudoword spelling. Misspelling error analyses further revealed that although the Chinese speakers were as likely as the alphabetic speakers to produce misspellings that resembled target words in visual form and individual phonemes, they were less likely to produce misspellings that can be read to sound exactly like the target words. In addition, there was evidence for the importance of phonological reading skills, working memory and syntactic awareness in establishing a common model of spelling for children from diverse linguistic backgrounds. Overall, the findings suggest that children learning to read and spell in English as a second language are not necessarily at a disadvantage even if the structure of their first language significantly differs from that of English. However, there may be qualitative differences strategies used to spell that are attributable to differences in grapheme-phoneme mapping experience.

description: Using a 16.2 hr radio observation by the Australia Telescope Compact Array (ATCA) and archival Chandra data, we found $>5σ$ radio counterparts to 4 known and 3 new X-ray sources within the half-light radius ($r_\mathrm{h}$) of the Galactic globular cluster NGC 6397. The previously suggested millisecond pulsar (MSP) candidate, U18, is a steep-spectrum ($S_ν\propto ν^α$; $α=-2.0^{+0.4}_{-0.5}$) radio source with a 5.5 GHz flux density of $54.7\pm 4.3~\mathrm{μJy}$. We argue that U18 is most likely a "hidden" MSP that is continuously hidden by plasma shocked at the collision between the winds from the pulsar and companion star. The nondetection of radio pulsations so far is probably the result of enhanced scattering in this shocked wind. On the other hand, we observed 5.5 GHz flux of the known MSP PSR J1740-5340 (U12) to decrease by a factor of $>2.8$ during epochs of 1.4 GHz eclipse, indicating that the radio flux is absorbed in its shocked wind. If U18 is indeed a pulsar whose pulsations are scattered, we note the contrast with U12's flux decrease in eclipse, which argues for two different eclipse mechanisms at the same radio frequency. In addition to U12 and U18, we also found radio associations for 5 other Chandra X-ray sources, four of which are likely background galaxies. The last, U97, which shows strong H$α$ variability, is mysterious; it may be either a quiescent black hole low-mass X-ray binary, or something more unusual.

As a result, the composition-dependent gradation can produce a broad resonant plasmon band in the optical region, resulting in a large enhancement of the optical nonlinearity and hence a large figure of merit.

description: Within the scope of a spherically symmetric space-time we study the role of different types of matter in the formation of different configurations with spherical symmetries. Here we have considered matter with barotropic equation of state, scalar field, electromagnetic field and an interacting system of scalar and electromagnetic field as the source. Corresponding field equations are solved exploiting harmonic coordinates. An easy to handle method is proposed which allows one to have an idea about the possible behavior of the metric functions once the components of the EMT of the source field is known.

description: Telephone-cord patterns have been recently observed in smectic liquid crystal capillaries. In this paper we analyse the effects that may induce them. As long as the capillary keeps its linear shape, we show that a nonzero chiral cholesteric pitch favors the SmA*-SmC* transition. However, neither the cholesteric pitch nor the presence of an intrinsic bending stress are able to give rise to a curved capillary shape. The key ingredient for the telephone-cord instability is spontaneous polarization. The free energy minimizer of a spontaneously polarized SmA* is attained on a planar capillary, characterized by a nonzero curvature. More interestingly, in the SmC* phase the combined effect of the molecular tilt and the spontaneous polarization pushes towards a helicoidal capillary shape, with nonzero curvature and torsion.

In this study shown the ordinary senior tourist visiting rural areas, and also shown the behavior of people vacationing there. Topics discussed included the reasons for choosing this form of tourism, as well as the choice of a particular offer, used by tourists source of information about the object, the preferred leisure activities and expectations for the diversify and improve the offer. The results indicate that rural tourism is very popular among the well-educated residents of large cities. The reason for choosing this form of tourism is most often the opportunity to relax in peace and tranquility and contact with nature. The criterion for selection of specific offer is the standard object and the qualities of the village. Seniors break in the countryside taking physical activity most often choose hiking and biking. It should be noted also interest in the culture of rural areas.

Theory of electrical conductivities of ferrogels

Publisher: name: arXiv
Year: 2004
Subjects: subject: Chemical Physics (physics.chem-ph)
subject: FOS: Physical sciences

description: Conductive organic polymers can be formulated with polymers that incorporate fine dispersed metallic particles. In this work, we present a general model for ferrogels which are chemically cross-linked polymer networks swollen with a ferrofluid. Our aim is to study the effect of the shape and/or material (conductivity) anisotropy on the effective electrical conductivity of the ferrogel in the presence of an external magnetic field. Our theory can reproduce the known results, and provides a link between the particle property and orientation distribution and the effective electrical conductivity. To this end, we find that material (conductivity) anisotropies are more important to yield a high effective electrical conductivity than shape anisotropies, while magnetic fields can offer a correction.

To achieve this goal used empirical data from farms specializing in field crops that collected the data from 2005 to 2011 for Farm Accountancy Data Network (FADN). Using a parametric method, Stochastic Frontier Analysis (SFA) analyzed the group of farms that was divided into three groups in depend on the ratio of technical efficiency. Then they were subjected to a comparative analysis of production capacity, organization and structure of production, economic efficiency and severity investment. It was found that technically efficient farms are those which were characterized by the smallest amount of work per 1 ha, had the greatest area of arable land, the best-labor and a favorable economic situation.
Teacher’s responses to student bullying
Creators: name: Cholewka, Sheena Marie
Publisher: name: University of British Columbia
Year: 2010

description: This study investigated teachers’ responses to student bullying. Of specific interest was whether or not teachers’ responses to student bullying varied according to the type of bullying, the nature of the power differential between the students involved, teacher gender, and student gender. With a fully crossed repeated measures design, secondary school teachers’ reactions (N = 133) were assessed on the same dependent variables repeatedly across six unique hypothetical bullying vignettes that varied in terms of the type of bullying (physical, verbal, and social), perpetrated by same sex peers (either female or male students) who exhibited different types of power advantages over the victimized student (physical or social). For each vignette, teachers were asked to describe their perceptions of the seriousness of the behavior, their identification of incident as bullying, their judgments of an existing rule or policy regarding such behavior, the acceptability of bullying in the absence of a rule or policy, the likelihood of intervention, and their proposed responses. Results indicated that the type of bullying involved-physical, social, verbal-was critical in determining teachers’ responses to bullying. Generally, teachers were more responsive to verbal bullying than physical bullying and, in turn, more responsive to physical bullying than social bullying. In particular, verbal bullying was more likely to be perceived as serious, more likely to considered for intervention, and more likely to be reported or deferred to others, especially relative to social bullying. The discussion of the major findings considers implications for educational practice and research.

description: The electronic bands of twisted bilayer graphene (TBLG) with a large-period moiré superlattice fracture to form narrow Bloch minibands that are spectrally isolated by forbidden energy gaps from remote dispersive bands. When these gaps are sufficiently large, one can study a band-projected Hamiltonian that correctly represents the dynamics within the minibands. This inevitably introduces nontrivial geometrical constraints that arise from the assumed form of the projection. Here we show that this choice has a profound consequence in a low-energy experimentally-observable signature which therefore can be used to tightly constrain the analytic form of the appropriate low-energy theory. We find that this can be accomplished by a careful analysis of the electron density produced by backscattering of Bloch waves from an impurity potential localized on the moiré superlattice scale. We provide numerical estimates of the effect that can guide experimental work to clearly discriminate between competing models for the low-energy band structure.

description: Στις αρχές της δεκαετίας του 2000 εισήχθη στην επιστημονική κοινότητα ο όρος των προσθετικών υψηλής απόδοσης. Χρησιμοποιώντας ανθρακο-νήματα και προηγμένης τεχνολογίας ψηφιακούς μηχανισμούς, οι προγραμματιστές, οι εμβιομηχανικοί και οι προσθετικοί κατάφεραν να δημιουργήσουν προσθετικά που να είναι μηχανοκίνητα και προσαρμόσιμα σε οποιοδήποτε έδαφος και δραστηριότητα. Ο κύριος σκοπός της εργασίας αυτής είναι η μελέτη και η ανάλυση των προσθετικών μελών των κάτω άκρων τόσο σε θεωρητικό όσο και σε πρακτικό μέρος. Στη διπλωματική εργασία γίνεται αναφορά στην ανατομία των κάτω άκρων, στα αίτια του ακρωτηριασμού, στα υλικά των προσθετικών μελών, στα είδη των προσθετικών μελών, στην σωστή αποκατάσταση των ασθενών μετά τον ακρωτηριασμό και προφανώς στην κατάλληλη επιλογή προσθετικού μέλους. Υλικά και Μεθοδολογία: Τα υλικά που χρησιμοποιήσαμε ήταν ένα χρονόμετρο ακριβείας τύπου Amila Chronograph, Junsd, 1-100seconds , JS-306 και μια μετρητική ταινία. H μεθοδολογία που ακολουθήσαμε είναι η εξής. Αρχικά, μοιράστηκε στους ασθενείς ένα ερωτηματολόγιο το οποίο κάλυπτε έναν όγκο ερωτήσεων και έπειτα βρήκαμε τα ποσοστά τεσσάρων ερευνητικών ερωτημάτων. Τα ερωτήματα αυτά ήταν η εύρεση του ποσοστού των ατόμων που έχουν μηχανικό, υδραυλικό και ηλεκτρονικό προσθετικό πόδι, η εύρεση του χρόνου που απαιτείται από ένα άτομο για να εκτελέσει μια κίνηση, ο βαθμός δυσκολίας ανεβάσματος της μπάρας του εργαστηρίου, τα λεπτά που βάδιζαν οι ασθενείς χωρίς να τους ενοχλεί το προσθετικό τους πόδι και τέλος ο χρόνος που έκαναν οι ασθενείς από την στιγμή που σηκώνονται από την καρέκλα μέχρι να ξανά κάτσουν. Αποτελέσματα: Οι περισσότεροι ασθενείς προτιμούν τη χρήση μηχανικού προσθετικού μέλους αντί για υδραυλικό ή ηλεκτρονικό. Οι χρόνοι εκτέλεσης κινήσεων των ασθενών με προσθετικό μέλος δεν διαφέρουν και πολύ από τα άτομα που δεν χρησιμοποιούν κάποιο πρόσθετο μέλος. Επίσης, από τα αποτελέσματα που βρίσκονται στο κεφάλαιο 4 παρατηρούμε ότι η πλειοψηφία των ασθενών δεν αντιμετωπίζει μεγάλη δυσκολία προκειμένου να ανέβει την μπάρα του εργαστηρίου όπου εκτελέστηκαν τα πειράματα. Συμπεράσματα : Εύκολα συμπεραίνουμε ότι οι ασθενείς διαλέγουν το προσθετικό τους μέλος ανάλογα με τις δραστηριότητες που εκτελούν μέσα στην ημέρα και προφανώς με γνώμονα το σημείο του ακρωτηριασμού. Επιπλέον, όσο αφορά τις καθημερινές τους κινήσεις παρατηρούμε ότι εκτελούνται με σχετική ευκολία.

description: We exploit magnetostriction in polydisperse ferrofluids in order to generate nonlinear responses, and apply a thermodynamical method to derive the desired nonlinear magnetic susceptibility. For an ideal gas, this method has been demonstrated to be in excellent agreement with a statistical method. In the presence of a sinusoidal ac magnetic field, the magnetization of the polydisperse ferrofluid contains higher-order harmonics, which can be extracted analytically by using a perturbation approach. We find that the harmonics are sensitive to the particle distribution and the degree of field-induced anisotropy of the system. In addition, we find that the magnetization is higher in the polydisperse system than in the monodisperse one, as also found by a recent Monte Carlo simulation. Thus, it seems possible to detect the size distribution in a polydisperse ferrofluid by measuring the harmonics of the magnetization under the influence of magnetostriction.

Research were carried out in 2006 on the test 1000 persons and in 2012 on the test 1100 consumers. The test had a character all-Polish, random and representative. The results showed a growth in the participation in the trade of dairy products by modern types of shops, mainly discounts, and a decrease in this participation of traditional groceries. Furthermore, research shows that the participation of persons consuming dairy products at all increased on average from about 17.2% (from 56.4% to 73.6%). However, frequency of consumption of these products depending on their kinds was subject to large differentiations between the examined years.

description: We report the first experimental observation of nonlinear self-trapping of Bose-condensed 87Rb atoms in a one dimensional waveguide with a superimposed deep periodic potential . The trapping effect is confirmed directly by imaging the atomic spatial distribution. Increasing the nonlinearity we move the system from the diffusive regime, characterized by an expansion of the condensate, to the nonlinearity dominated self-trapping regime, where the initial expansion stops and the width remains finite. The data are in quantitative agreement with the solutions of the corresponding discrete nonlinear equation. Our results reveal that the effect of nonlinear self-trapping is of local nature, and is closely related to the macroscopic self-trapping phenomenon already predicted for double-well systems.

Zufolge der hohen Anzahl von am Markt konkurrierenden Firmen ist es in dieser Phase innerhalb von kürzester Zeit notwendig, die maßgebenden Randbedingungen und Risikofaktoren des Projektes zu erkennen, die den Projekterfolg wesentlich bestimmen. Diese individuellen Projekteigenschaften ergeben sich aus rechtlichen, technischen oder wirtschaftlichen Vorgaben, die einzuhalten sind, um einen gewünschten Projekterfolg mit hoher Wahrscheinlichkeit sicher zu stellen. Diese Diplomarbeit befasst sich einerseits mit diesen Vorgaben, andererseits schließt sie aus diesen Vorgaben praxisbezogene Risiken des Wiener freifinanzierten Wohnbaus. Diese Gefährdungen werden in Form eines Kataloges zusammengefasst und geben dem Leser einen Einblick in die Komplexität der Bauträgertätigkeit.
description: The following diploma thesis examines decision criteria for the development of Viennese privately financed residential real estate projects. The phase prior to the location provision is essential for the success of the program. Due to the high number of companies competing on the market, it is necessary within a short period of time to recognize the decisive conditions and risk factors of the project, which essentially determine its success. These individual project characteristics result from the juridical, technical or economic requirements which must be adhered to in order to ensure the desired success with the highest probability. On one hand, this diploma thesis deals with these requirements; on the other hand, it concludes from these guidelines the practice-related risks of Vienna's privately financed housing. These risks are summarized in the form of a catalog and give the reader an insight into the complexity of the developers activities.

Signs of enhancement? : a comparison of visual spatial skill in signers and non-signers
Creators: name: Springford, Janice A.
Publisher: name: University of British Columbia
Year: 2011

description: The effect of sign language experience on performance of visual spatial tasks was investigated in this study. Performance by signers and non-signers was compared on the Knox's Cube Test—Revised (KCT—R) in standard and experimental administrations, Color Trails Test Parts 1 & 2 (Form A) (CTT), and the Benton Test of Facial Recognition (BFT). Participants were 30 Deaf adult signers, 28 hearing adult signers, and 30 hearing adult non-signers. Deaf and hearing signers were also compared as subgroups of 1) native signers who learned sign language from their Deaf signing parents and 2) non-native signers who began to learn sign language later in childhood or in adulthood. Analysis of variance on raw and/or total scores indicated that hearing signers outperformed non-signers significantly on the CTT, Part 2. Both Deaf and hearing signers significantly outperformed non-signers on the CTT, Part 1. Differences between hearing signers and non-signers approached significance on the experimental administration of the KCT-R. No differences between signers and non-signers were found on the Benton Test or the KCT-R, standard administration. This study suggests that sign language experience may be enhancing some general visual spatial skills.

description: Having in mind the fact that the reduction and loss of relatively small part of environmental assets and nature values affect their development opportunities in the future, it is necessary to undertake the measures preventing the depletion of any of its components. The environment should be considered as one of principal elements of the development. The action improving the state of the environment through spatial development, enhancement of water, soil and air quality, as well as rational usage of natural assets should be taken. The type of taken actions depends on the way and range of using the environment at the local level. Each community has to adjust its activities taking into account environmental aspects. The research regarding identification and assessment of the activities in terms of shaping environmental dimension of rural areas of Lower Silesian Province has shown certain diversity according to particular communities and regions.

description: We investigate the bulk rheology of dense granular flow down a rough slope, where the density profile has been found to show a plateau except for the boundary layers in simulations [Silbert {\it et al.}, Phys. Rev. E {\bf 64}, 051302 (2001)]. It is demonstrated that both the Bagnold scaling and the framework of kinetic theory are applicable in the bulk, which allows us to extract the constitutive relations from simulation data. The detailed comparison of our data with the kinetic theory shows quantitative agreement for the normal and shear stresses, but there exists slight discrepancy in the energy dissipation, which causes rather large disagreement in the kinetic theory analysis of the flow.

description: We investigate the superfluid-to-normal zero temperature quantum phase transitions of asymmetric two-component Fermi gases as a function of the chemical potential imbalance $h$. The calculations are performed for homogeneous and trapped imbalanced systems. We concentrate at unitarity, characterized by a divergent interaction parameter $k_F a$, where most of the current experiments are realized. For homogeneous systems, we determine the critical chemical potential imbalance $h_c$ at which possible phase transitions occur. In the case of trapped gases, we show how $h_c$ can be consistently determined from experimental observations.

The organizational climate of Omani schools in relation to teachers’ sense of efficacy : a multilevel examination of the mediating effects of teachers’ perceived collective efficacy
Creators: name: Aldhafri, Said Suliman
Publisher: name: University of British Columbia
Year: 2010

description: In the current study, which examines the relationship between schools’ organizational climates and teachers’ sense of efficacy, I developed a conceptual framework in which teachers’ perceived collective efficacy (TPCE) was proposed to mediate the relationships between four dimensions of school climate and teachers’ sense of efficacy. These dimensions included: collegial leadership, teacher professionalism, academic press, and community engagement. The sample consisted of 2,381 surveys (obtained from 98 schools) of Arabic elementary teachers from the Sultanate of Oman. These teachers volunteered to complete three measures assessing their individual efficacy beliefs (the Teacher Sense of Efficacy Scale), their perceived collective efficacy (the Teachers’ Perceived Collective Efficacy Scale), and their perceptions of school climate (the School Climate Index). These measures were adapted through a comprehensive test adaptation (following the International Test Commission’s guidelines) that involved two pilot studies. A hierarchical linear modeling (HLM) technique was applied to examine the nine hypotheses proposed to answer the two main questions guiding the present study: What dimensions of school climate directly predict teachers’ sense of efficacy? And what is the role, if any, of TPCE in the relationship between these school climate dimensions and teachers’ sense of efficacy? As proposed, TPCE mediated the effects of two school climate dimensions on teachers’ sense of efficacy. Supporting previous research, teacher professionalism and community engagement dimensions influenced teachers’ sense of efficacy directly and indirectly through TPCE. The effects of these two dimensions were greater on TPCE than on teachers’ sense of efficacy. Based on the construct validity evidence obtained for the three measures, the findings indicate that when teachers respect, support, and collaborate with each other and when the community is positively engaged in school activity, TPCE is enhanced, along with teachers’ sense of efficacy. Contrary to what was proposed, however, neither collegial leadership nor academic press was a statistically significant predictor of either teachers’ sense of efficacy or TPCE. While these two variables showed high bivariate correlations with both efficacy belief constructs, their effects disappeared in the presence of other dimensions of school climate. The study concludes with a discussion of its implications, limitations, and future research recommendations.

When does the onset of multiple stellar populations in star clusters occur-III: No evidence of significant chemical variations in main-sequence stars of NGC 419

description: Recent studies have revealed that the onset age for the presence of multiple stellar populations (MPs) in star clusters seems to correspond to the disappearance of the extended main-sequence turnoff (eMSTO) in young clusters, a pattern associated with stellar rotations. A speculative suggestion is that MPs might be caused by the magnetic brake, a stellar evolutionary effect linked to the rotation. In this work, we use the young massive cluster NGC 419 as a testbed. We examined if its magnetically baked MS stars would exhibit MPs. Using the deep ultraviolet and visible images observed through the Hubble Space Telescope, combined with a specific color index that is sensitive to the nitrogen (N) abundance, we examined if its late G- and K-type MS stars are affected by N variation. Our analysis reports that the morphology of its GK-type MS is most likely an SSP, and only a negligible probability that indicates a N variation up to 0.4 dex is present. We conclude that there is no significant N variation among its GK-type MS stars. The absence of a significant chemical variation among the late-type MS stars indicates that MPs might not be a specific pattern of magnetically braked stars.

title: A reduced basis method for fractional diffusion operators

Subjects: subject: Fractional Diffusion
subject: Reduced Basis Method

description: in Englisch
description: Several authors have proposed and analyzed numerical methods for fractional differential oper- ators, in particular Fourier Galerkin schemes and Caffarelli-Silvestre extensions. In this thesis we consider a different approach. By means of a reduced basis method, the desired operator is projected to a low dimensional space V r , where the fractional power can be directly evaluated via the eigen-system. The optimal choice of V r is provided by the so called Zolotarëv points, en- suring exponential convergence. Numerical experiments evaluating the operator and the inverse operator confirm the analysis. The time-dependent Fractional Cahn-Hilliard Equation (FCHE) is examined for further tests. By a splitting method, the non-linear operator is decoupled from the regular Laplacian, such that the linear parabolic equation is solved exactly on the low dimensional reduced space. Different choices of the fractional power s are discussed and tested.
