English as a second language

description: In the era of fast-paced world, linguistic competence alone is insufficient because an individual must be aware of cultural appropriateness and differences. For that reason, the significance of intercultural competence in English instruction is increasingly and timely relevant. Teachers' awareness and perceptions of intercultural competence are critical in promoting students' learning of intercultural competence in English classes. This research aims to examine 10 Thai EFL teachers' perceptions of intercultural competence and how they apply intercultural competence to English classes. The conceptual framework was under the analysis of the Process Model of Intercultural competence (Deardorff, 2006) and Thailand Basic Education Core Curriculum (Ministry of Education, 2008). Participants were chosen randomly from secondary schools around Thailand. A self-perception questionnaire, personal interviews, and a self-feedback report were employed to collect and analyse both qualitative and quantitative data. The findings showed that most participants had an intermediate level of integration of intercultural teaching. Moreover, priority was given to teaching English intercultural ‘knowledge’, ‘skills’, ‘attitudes', and ‘assessment’ respectively. Conclusions suggest that integrating intercultural competence in English classes by covering all components of intercultural competence could facilitate students building relationships with people from different cultural backgrounds.

description: The main objective of this study was to assess the IFRS adoption project in Nib International Bank S.C. The specific objectives were to examine the present status of IFRS adoption project, to explore the prospects and challenges of IFRS adoption project, and to assess the readiness process of IFRS project in Nib International Bank. To meet the research objectives, both primary and secondary sources of data were used in the study. The study used two separate questionnaires and one key informant interview as tools to collect the primary data while documentary reviews were used to gather the secondary data required for the study. The total population of the study constituted 3 project steering committee members, 7 project team members and 280 operational staffs. From the 280 operational staff, with the use of Yamane's simplified sample formula, a total of 165 respondents were selected as sample population of the study. In general, the total population of the study aggregated to 175 which were the sum of 165 sampled operational staff, 7 project staff and 3 project steering committee members. Data collected from the above sources were analyzed using both quantitative and qualitative data analysis tools. For the most part, qualitative data analysis techniques such as in-depth discussions and expositions were used. Meanwhile, frequencies and percentages were used for analyzing the quantitative data. The major findings of the study results from both primary and secondary data sources demonstrated that the project is in implementation stage and that it is still in progress. In relation to the prospect of the project, it was indicated that the project initiates new thinking, harnesses professionalism, smoothens the Bank's correspondent relationship, helps in redefining and rejuvenating the existing work process and finally allows for fair presentation of financial condition of the Bank. There are also challenges that are associated with adopting IFRS in the Bank. Some of the major challenges identified by the respondents of the study incorporated; IFRS Knowledge Gap and lack of benchmarking, absence of mandatory infrastructures, disparity between existing laws and IFRS requirement, absence of a holistic approach to project management, loss of commitment to the project and resistance to change. The other major findings suggest that there are people, process and system readiness issue in the project. Based on the results of the study it was recommended that the Bank should focus on those issues that are internal to it so as to ensure the successful completion of the project on or before the regulatory deadline

description: Composing fashion outfits involves deep understanding of fashion standards while incorporating creativity for choosing multiple fashion items (e.g., Jewelry, Bag, Pants, Dress). In fashion websites, popular or high-quality fashion outfits are usually designed by fashion experts and followed by large audiences. In this paper, we propose a machine learning system to compose fashion outfits automatically. The core of the proposed automatic composition system is to score fashion outfit candidates based on the appearances and meta-data. We propose to leverage outfit popularity on fashion oriented websites to supervise the scoring component. The scoring component is a multi-modal multi-instance deep learning system that evaluates instance aesthetics and set compatibility simultaneously. In order to train and evaluate the proposed composition system, we have collected a large scale fashion outfit dataset with 195K outfits and 368K fashion items from Polyvore. Although the fashion outfit scoring and composition is rather challenging, we have achieved an AUC of 85% for the scoring component, and an accuracy of 77% for a constrained composition task.

description: A characteristic dependence of voltage control of perpendicular magnetic anisotropy (VCMA) on oxygen migration at Fe/MgO interfaces was revealed by performing systematic {\it ab initio} study of the energetics of the oxygen path around the interface. We find that the surface anisotropy energy exhibits a Boltzmann sigmoidal behavior as a function of the migrated O-atoms concentration. The obtained variation of the VCMA efficiency factor $β$ reveals a saturation limit beyond a critical concentration of migrated O, about $54\%$, at which the anisotropy switches from perpendicular to in plane. Furthermore, depending on the range of variation of the applied voltage, two regimes associated with reversible or irreversible ions displacement are predicted to occur, yielding different VCMA response. According to our findings, one can distinguish from the order of magnitude of $β$ the VCMA driving mechanism: an effect of several tens of fJ/(V.m) is likely associated to charge-mediated effect combined with slight reversible oxygen displacements whereas an effect of the order of thousands of fJ/(V.m) is more likely associated with irreversible oxygen ionic migration.

description: We suggest a class of two-dimensional lattice spin Hamiltonians describing non-Abelian SU(2) chiral spin liquids - spin-analogues of fractional non-Abelian quantum Hall states- with gapped bulk and gapless chiral edge excitations described by the SU(2)$_n$ Wess-Zumino-Novikov-Witten conformal field theory. The models are constructed from an array of a generalized spin-$n/2$ ladders with multi-spin exchange interaction which are coupled by isolated spins. Such models allow a controllable analytic treatment starting from the one-dimensional limit and are characterized by a bulk gap and non-Abelian SU(2)$_n$ gapless edge excitations.

description: Learning tasks such as those involving genomic data often poses a serious challenge: the number of input features can be orders of magnitude larger than the number of training examples, making it difficult to avoid overfitting, even when using the known regularization techniques. We focus here on tasks in which the input is a description of the genetic variation specific to a patient, the single nucleotide polymorphisms (SNPs), yielding millions of ternary inputs. Improving the ability of deep learning to handle such datasets could have an important impact in precision medicine, where high-dimensional data regarding a particular patient is used to make predictions of interest. Even though the amount of data for such tasks is increasing, this mismatch between the number of examples and the number of inputs remains a concern. Naive implementations of classifier neural networks involve a huge number of free parameters in their first layer: each input feature is associated with as many parameters as there are hidden units. We propose a novel neural network parametrization which considerably reduces the number of free parameters. It is based on the idea that we can first learn or provide a distributed representation for each input feature (e.g. for each position in the genome where variations are observed), and then learn (with another neural network called the parameter prediction network) how to map a feature's distributed representation to the vector of parameters specific to that feature in the classifier neural network (the weights which link the value of the feature to each of the hidden units). We show experimentally on a population stratification task of interest to medical studies that the proposed approach can significantly reduce both the number of parameters and the error rate of the classifier.

The Effect of Project Manager's Leadership Style and Teamwork on Project Performance: the case of HELVETAS Swiss Intercooperation Ethiopia
Creators: name: Shumiye, Alem
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The purpose of this study was to establish the relationship between leadership style and teamwork and their effect on performance of projects in HELVETAS. The theoretical foundation of this study was guided by visionary leadership theory which involved transformational and transactional leadership styles. In this study, a mixed of both qualitative and quantitative research approaches was employed with mixed research design of descriptive and explanatory research. Using web-based Multi-Factorial Leadership Questionnaire (MLQ), complete and usable primary data were collected from 233 project managers and project team members. A test on adequacy of the sample, reliability and validity of the measurement model were found to be acceptable. Model diagnostic tests show assumptions of normality, autocorrelation, multicollinearity and homoscedasticity hold true. Step-wise multiple regression analysis shows that leadership style had a statistically significant positive effect on project performance; transformational leadership style was positively related to teamwork while transactional leadership style is negative related to project performance. Team communication aspect of teamwork was positively related to project performance while team collaboration and team cohesion were negatively related to project performance. In addition, the study found that teamwork was a partial mediator of the relationship between leadership style and project performance. This study recommends that, as project leader alone cannot successfully complete a project, project managers should select and adopt appropriate transformational and transactional leadership styles taking into account the critical role of teamwork. Based on the findings, senior management team in HELVETAS should act on leadership and team development programs (such as action learning) as well as staff retention strategies along the project life cycle. The study contributes to project management literature by integrating leadership theory and teamwork model.

description: The identification of fossilizable correlates to ecology is essential for estimating the biology of extinct organisms. Among birds, reconstructions of brain shape and wing shape can elucidate macroevolutionary patterns in sensory and locomotory ecology. Here, I use these data to estimate traits ancestral to the crown avian divergence that may have contributed to their exceptional survival of the end-Cretaceous extinction event, as well as to the basal divergences within Palaeognathae, a clade marked by repeated losses of flight and gigantism. First, I use digital brain reconstructions to investigate the evolution of palaeognath sensory ecology. I find relatively large olfactory bulbs in taxa occupying forested environments where visual cues used in foraging are likely to be limited. Elephant birds exhibited extremely reduced or obsolete optic lobes, a condition only observed among extant birds in nocturnal taxa. I interpret these results as evidence for nocturnality among elephant birds. Next, I reconstruct the wing of an exceptionally preserved specimen of the Early Eocene lithornithid Calciavis grandei. Lithornithids are stem flying palaeognaths, and investigations of properties of their wings informs estimation of ancestral traits in Palaeognathae. My comparison of flight parameters estimated for Calciavis with representatives from across Aves show that it was likely capable of sustained flight and migratory behavior, consistent with previous hypotheses the ancestors of extant palaeognath lineages may also have been capable of sustained flight. Finally, I use data from a new, nearly complete skull of Late Cretaceous (~70 Ma) near-crown bird Ichthyornis to interrogate hypotheses proposed to explain patterns of dinosaur survivorship of the end-Cretaceous mass extinction and reassess bird body size evolution. These hypotheses demand identification of traits unique to survivors in Aves. However, identification of such traits is complicated by data available from stem birds. Ichthyornis exhibited a wulst and segmented palate, features with controversial evolutionary timing. The origin of Aves is marked by larger, highly flexed brains indicating selection for relatively large telencephela and eyes but were not uniquely small bodied. Sensory system differences, potentially linked to these shifts, may help explain avian survivorship relative to other dinosaurs.

description: We extend an alternative, phenomenological approach to inflation by means of an equation of state and a sound speed, both of them functions of the number of $e$-folds and four phenomenological parameters. This approach captures a number of possible inflationary models, including those with non-canonical kinetic terms or scale-dependent non-gaussianities. We perform Markov Chain Monte Carlo analyses using the latest cosmological publicly available measurements, which include Cosmic Microwave Background (CMB) data from the Planck satellite. Within this parametrization, we discard scale invariance with a significance of about $10σ$, and the running of the spectral index is constrained as $α_s=-0.60\,^{+0.08}_{-0.10}\times 10^{-3}$ ($68\%$~CL errors). The limit on the tensor-to-scalar ratio is $r<0.005$ at $95\%$~CL from CMB data alone. We find no significant evidence for this alternative parameterization with present cosmological observations. The maximum amplitude of the equilateral non-gaussianity that we obtain, $|f^{\text{equil}}_{\text{NL}}|< 1$, is much smaller than the current Planck mission errors, strengthening the case for future high-redshift, all-sky surveys, which could reach the required accuracy on equilateral non-gaussianities.

description: Aufgrund der oftmals faszinierenden biologischen Eigenschaften allenischer Naturstoffe aber auch Allen-substituierter, pharmakologisch aktiver Verbindungsklassen mit beachtlichen Enzym-inhibierenden, cytostatischen oder antiviralen Eigenschaften sind Allene längst weitaus mehr als nur theoretische Kuriositäten. Eine besonders interessante und vielseitige Gruppe unter den Allenen stellen α-Hydroxyallene dar. Die anti-stereoselektive Kupferhydrid-katalysierte SN2'-Reduktion von Propargylelektrophilen ermöglicht einen wichtigen Zugang zu α-Hydroxyallenen in hohen Ausbeuten und mit exzellentem Chiralitätstransfer und toleriert dabei eine Vielfalt funktioneller Gruppen. In dem zweiten Kapitel dieser Arbeit werden die mechanistischen Untersuchungen der Kupferhydrid-katalysierten SN2'-Reduktion von Propargylepoxiden unter Zuhilfenahme von computerchemischen Berechnungen und ergänzenden kinetischen Untersuchungen vorgestellt. Damit wird es möglich die hohe anti-Selektivität der Allenbildung zu verstehen und so einen größeren Einfluss auf diese Reaktion zu gewinnen. Eine direkte enantioselektive Synthese von Allenen mittels SN2'-Substitution aus achiralen Vorgängern unter Verwendung eines chiralen Übergangsmetall-Katalysators bietet den Vorteil, nicht auf die Verfügbarkeit von enantiomerenreinen Derivaten angewiesen zu sein und ist daher besonders erstrebenswert. Deshalb werden im dritten Kapitel dieser Arbeit im Rahmen einer kinetischen Racematspaltung verschiedene chirale N-Heterocyclische Carbenvorläufer in der Allensynthese durch Kupferhydrid-katalysierte SN2’-Reduktion untersucht. Hierdurch soll das Repertoire der Allenchemie um neue Möglichkeiten der enantioselektiven Synthese erweitert werden. C-Glycoside als Pharmakophore der O-Glycoside kommen gehäuft in biologisch wichtigen Naturstoffen und pharmazeutisch relevanten Substanzklassen vor. Sie sind zudem als stabile Mimetika der O- und N-Glycoside mit identischen oder nur leicht veränderten biochemischen Eigenschaften von großer Bedeutung. Dabei bringen sie den entscheidenden Vorteil einer Resistenz gegenüber hydrolytischer und enzymatischer Spaltung mit sich. Das im vierten Kapitel dieser Arbeit behandelte Projekt widmet sich daher der Synthese eines entsprechenden C-Glycopyranosid-Analogons und ermöglicht einen neuen, hochgradig stereoselektiven Zugang zu multisubstituierten benzylischen α-C-Glycopyranosiden mittels Kupfer- und Goldkatalyse.

description: Thermal systems have traditionally been modeled via Euclideanized space by analytical continuation of time to an imaginary time. We extend the concept to static thermal gradients by recasting the temperature variation as a variation in the Euclidean metric. We apply this prescription to determine the Quark anti-Quark potential in a system with thermal gradient. A naturally occurring QCD medium with thermal gradients is a Quark Gluon Plasma (QGP). However, the QGP evolves in time. Hence, we use a quasi-stationary approximation, which is applicable only if the rate of time evolution is slow. The application of our proposal to a Quark anti-Quark potential in QGP can be seen as a step towards a more exact theory which would incorporate time varying thermal gradients. The effect of a static temperature gradient on the Quark anti-Quark potential is analyzed using a gravity dual model. A non-uniform black string metric is developed, by perturbing the Schwarzchild metric, which allows to incorporate the temperature gradient in the dual AdS space. Finally, an expression for the Quark anti-Quark potential, in the presence of a static temperature gradient, is derived.

description: Using a Besov topology on spaces of modelled distributions in the framework of Hairer's regularity structures, we prove the reconstruction theorem on these Besov spaces with negative regularity. The Besov spaces of modelled distributions are shown to be UMD Banach spaces and of martingale type $2$. As a consequence, this gives access to a rich stochastic integration theory and to existence and uniqueness results for mild solutions of semilinear stochastic partial differential equations in these spaces of modelled distributions and for distribution-valued SDEs. Furthermore, we provide a Fubini type theorem allowing to interchange the order of stochastic integration and reconstruction.

description: We investigate how an equation of state for matter is affected when a gravity is present. For this purpose, we consider a box of ideal gas in the presence of Newtonian gravity. In addition to the ordinary thermodynamic quantities, a characteristic variable that represents a weight per unit area relative to the average pressure is required in order to describe a macroscopic state of the gas. Although the density and the pressure are not uniform due to the presence of gravity, the ideal gas law itself is satisfied for the thermodynamic quantities when averaged over the system. Assuming that the system follows an adiabatic process further, we obtain a {\it new} relation between the averaged pressure and density, which differs from the conventional equation of state for the ideal gas in the absence of gravity. Applying our results to a small volume in a Newtonian star, however, we find that the conventional one is reliable for most astrophysical situations when the characteristic scale is small. On the other hand, gravity effects become significant near the surface of a Newtonian star.

description: In many stochastic dynamical systems, ordinary chaotic behavior is preceded by a full-dimensional phase that exhibits 1/f-type power-spectra and/or scale-free statistics of (anti)instantons such as neuroavalanches, earthquakes, etc. In contrast with the phenomenological concept of self-organized criticality, the recently developed approximation-free supersymmetric theory of stochastic differential equations, or stochastics, (STS) identifies this phase as the noise-induced chaos (N-phase), i.e., the phase where the topological supersymmetry pertaining to all stochastic dynamical systems is broken spontaneously by the condensation of the noise-induced (anti-)instantons. Here, we support this picture in the context of neurodynamics. We study a 1D chain of neuron-like elements and find that the dynamics in the N-phase is indeed featured by positive stochastic Lyapunov exponents and dominated by (anti)instantonic processes of (creation)annihilation of kinks and antikinks, which can be viewed as predecessors of boundaries of neuroavalanches. We also construct the phase diagram of emulated stochastic neurodynamics on Spikey neuromorphic hardware and demonstrate that the width of the N-phase vanishes in the deterministic limit in accordance with STS. As a first result of the application of STS to neurodynamics comes the conclusion that a conscious brain can reside only in the N-phase.

description: Immer mehr Unternehmen der Old-Economy (Energieversorgungsunternehmen, Versicherungsunternehmen, Kreditinstitute) öffnen sich dem elektronischen Handel, um einerseits neue Märkte zu erschließen und andererseits bestehende Märkte zu sichern und auszubauen. Im Gegensatz zu Unternehmen der New Economy (Amazon, EBay, Consors), die über eine auf die Anforderungen des Electronic Commerce speziell ausgerichtete Hard- und Softwareinfrastruktur verfügen, haben die Unternehmen der Old-Economy Legacy-Systeme im Einsatz, mit denen sie ihr bisheriges Geschäft unterstützt und abgewickelt haben. Die Daten und Funktionalitäten dieser Legacy-Systeme sollen in neuen zusätzlichen Electronic Commerce Anwendungen zur Unterstützung des elektronischen Handels genutzt werden. Die Möglichkeiten der Integration einer bestehenden Hard- und Softwareinfrastruktur mit neu entwickelten Electronic Commerce Anwendungen sowie die Integration der bisherigen Geschäftsprozesse mit elektronischen Geschäftsprozessen wird in diesem Beitrag beschrieben.

Unified quantum density matrix description of coherence and polarization

Subjects: subject: Quantum Physics (quant-ph)

description: The properties of coherence and polarization of light has been the subject of intense investigations and form the basis of many technological applications. These concepts which historically have been treated independently can now be formulated under a single classical theory. Here, we derive a quantum counterpart for this theory, with basis on a density matrix formulation, which describes jointly the coherence and polarization properties of an ensemble of photons. The method is used to show how the degree of polarization of a specific class of mixed states changes on propagation in free space, and how an interacting environment can suppress the coherence and polarization degrees of a general state. This last application can be particularly useful in the analysis of decoherence effects in optical quantum information implementations.

description: Barium ruthenate Ba$_{4}$Ru$_{3}$O$_{10}$, in which Ru$_{3}$O$_{12}$ trimers are connected together to form a chequered two-dimensional framework, has been synthesised and its structural, magnetic and transport properties studied between 300 K and 2 K. The paramagnetic to antiferromagnetic transition at $T_N \sim 105$ K evidenced on the susceptibility curve coincides with an increase of electron localization in transport measurements. Thermoelectric power and Hall coefficient measurements both exhibit dramatic changes at $T_N$, characteristic of a reconstruction of the bands structure near the Fermi level. No pronounced structural changes are observed at TN in this compound. The magnetic scattering signal on the neutron powder diffraction patterns below $T_N$ is weak, but can be tentatively modelled with an antiferromagnetic ordering of the spins at both ends of a trimer, the spin of the more symmetric Ru site remaining idle. Crystal field and strong spin-orbit coupling at the Ru$^{4+}$ site seem to be the key parameters to understand the magnetic state of Ba$_{4}$Ru$_{3}$O$_{10}$.
