description: Technological advancement in infrastructures such as transport and communication sector has created a global market that calls upon the corporate leaders to increase their international operations and relationships. The geographical location of a business is no longer a barrier to a potential market as the entrepreneurs have access to commercialized business environment that allows organizations to operate in more than one country. In terms of business ventures, the geographical boundaries are flattened, and the world made smaller through the quick mean of transportation through air, roads, rails, and water body. The integrated system in the transport and communication sector is of great benefit to the economic progress among countries as well as the fusion of different cultures into a global culture. Economic interdependence has resulted in international competition among companies with innovative technologies to meet the dynamic nature of the global culture. The study addresses a specific problem of cultural barriers between Europe and the Middle East in terms of business opportunities for international companies. The focus is on the UAE and European Union countries that exhibit distinct cultural norms and traditional practices. Addressing the cultural difference in Europe and the Middle East, there are many factors to consider before running an international company in both regions. Some of the cultural issues tackled in the paper include the branding of the product, the promotion approach, and handling of employees in a culturally diverse environment. Besides, there is a need to check on the institutional framework in the two countries and its impact on the business environment.
Behavioural and neuroimaging evidence of speed-tuned directional anisotropies in global motion perception
Creators: name: Zwicker, Amy Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: Research has suggested that directional anisotropies, or asymmetries, exist for global motion perception, yet there are inconsistencies among these results. The purpose of this study was to examine directional anisotropies in motion perception, to determine what motion parameters affect anisotropies, and to investigate cortical activation that may contribute to anisotropies. In Experiment 1, coherence thresholds were obtained from 40 subjects for direction discrimination of moving random dot patterns. Lower thresholds were found for centripetal and horizontal motion relative to centrifugal and vertical, respectively, when the speed of motion was 8 deg/s. For motion that was 1 deg/s, lower thresholds were found for upward motion relative to downward. These anisotropies were retested in 4 subjects in Experiment 2 with a detection paradigm; the fast motion anisotropies were confirmed but the slow motion anisotropy was not. Six participants completed an fMRI experiment in which the BOLD response to slow and fast directions of motion was measured. V5/MT+ was functionally defined; within this ROI greater activity was found for fast vertical motion relative to horizontal and fast centripetal motion relative to centrifugal. There were no differences in cortical activity for directions of slow motion. Both the behavioural and fMRI studies suggest that there are global motion pathways tuned to different speeds of motion. Within these speedtuned pathways, there is support for unique directional anisotropies in global motion processing.

description: The Chandra X-ray Observatory is finding a large number of cavities in the X-ray emitting intra-cluster medium which often coincide with the lobes of the central radio galaxy. We propose high-resolution Sunyaev-Zel'dovich (SZ) observations in order to infer the still unknown dynamically dominating component of the radio plasma bubbles. This work calculates the thermal and relativistic SZ emission of different compositions of these plasma bubbles while simultaneously allowing for the cluster's kinetic SZ effect. As examples, we present simulations of an Atacama Large Millimeter Array (ALMA) observation and of a Green Bank Telescope (GBT) observation of the cores of the Perseus cluster and Abell 2052. We predict a 5 sigma detection of the southern radio bubble of Perseus in a few hours with the GBT and ALMA while assuming a relativistic electron population within the bubble. In Abell 2052, a similar detection would require a few ten hours with either telescope, the longer exposures mainly being the result of the higher redshift and the lower central temperature of this cluster. Future high-sensitivity multi-frequency SZ observations will be able to infer the energy spectrum of the dynamically dominating electron population in order to measure its temperature or spectral characteristics. This knowledge can yield indirect indications for an underlying radio jet model.

description: Plasmonic structures are often fabricated by lithographic patterning of a thin metallic film. Properties of the thin film are intimately related to the quality of the resulting structures. Here we compare two kinds of thin gold films on silicon nitride membrane: a conventional polycrystalline thin film deposited by magnetron sputtering, and monocrystalline gold microplates which were chemically synthesised directly on the membrane's surface for the first time. Both pristine metals were used to fabricate plasmonic nanorods using focused ion beam lithography. Structural and optical properties of the nanorods were characterized by analytical transmission electron microscopy. The dimensions of the nanorods in both substrates reproduced well the designed size of $240 \times 80\ \mathrm{nm^2}$ with the deviations up to 20 nm in both length and width. The shape reproducibility was considerably improved among monocrystalline nanorods fabricated from the same microplate. Interestingly, monocrystal nanorods featured inclined boundaries while the boundaries of the polycrystal nanorods were upright. Q factors and peak loss probabilities of the modes in both structures are within the experimental uncertainty identical. We conclude that the optical response of the plasmonic antennas is not deteriorated when the polycrystalline metal is used instead of the monocrystalline metal.

description: We examine the fluid phase behaviour of the binary mixture of hard superellipses using the scaled particle theory The superellipse is a general two dimensional convex object which can be tuned between circular and rectangular shapes continuously at a given aspect ratio. We find that the shape of the particle affects strongly the stability of isotropic nematic and tetratic phases even if the aspect ratios of both species are fixed. While the isotropic isotropic demixing transition can be ruled out using the scaled particle theory the first order isotropic nematic and the nematic nematic demixing transition can be stabilized with strong fractionation between the components. It is observed that the demixing tendency is strongest in small rectangle large ellipse mixtures. Interestingly, it is possible to stabilize the tetratic order at lower densities in the mixture of hard squares and rectangles where the long rectangles form nematic phase, while the squares stay in tetratic order.

description: The ability to make fire is one of society‟s earliest and most essential innovations, but fire poses a significant threat when it gets out of control (Alam and Baroi, 2003, p.35). The impact of fire is frequently severe and has a devastating impact on its victims. Fires which affect the poorest of the poor are especially damaging; those people who are most vulnerable to the impact of fires yet least well equipped to deal with them (Ibem, 2011, p.27). Informal settlements (or slums) are widespread in the urban areas of many developing countries. Slums are particularly vulnerable to the risks posed by many disasters and are often home to impoverished communities who are frequently the poorest and most marginalised urban population (Pharoah, 2009, p.105)....

description: We present a new method, ePT, for extrapolating few known coefficients of a perturbative expansion. Controlled by comparisons with numerically exact quantum Monte Carlo (QMC) results, 10th order strong-coupling perturbation theory (PT) for the Hubbard model on the Bethe lattice is reliably extrapolated to infinite order. Within dynamical mean-field theory (DMFT), we obtain continuous estimates of energy E and double occupancy D with unprecedented precision O(10^{-5}) for the Mott insulator above its stability edge U_{c1}=4.78 as well as critical exponents. In addition, we derive corresponding precise estimates for E and D in the metallic ground state from extensive low-temperature QMC simulations using a fit to weak-coupling PT while enforcing thermodynamic consistency.

description: In a recent paper we have introduced a continuous version of the Maxwell demon (CMD) that is capable of extracting large amounts of work per cycle by repeated measurements of the state of the system. Here we underline its main features such as the role played by the Landauer limit in the average extracted work, the continuous character of the measurement process and the differences between our continuous Maxwell demon and an autonomous Maxwell demon. We demonstrate the reversal of Landauer's inequality depending on the thermodynamical and mechanical stability of the work extracting substance. We also emphasise the robustness of the Shannon definition of the information-content of the stored sequences in the limit where work extraction is maximal and fuelled by the large information-content of rare events.

description: Recent data of two-body nonleptonic $B$ meson decays allow a topological-amplitude analysis up to the $O(λ^2)$ accuracy, where $λ$ denotes the Wolfenstein parameter. We find a solution from the $B\toππ$ data and a solution from the $B\to Kπ$ data, which satisfy the approximate SU(3) flavor symmetry. These solutions indicate that the color-suppressed tree amplitude is large, all other amplitudes can be understood within the standard model, and the weak phases $ϕ_2\approx 90^o$ and $ϕ_3\approx 60^o$ are consistent with the global unitarity triangle fit.

description: Lattice structures are periodic porous bodies which are becoming popular since they are a good compromise between rigidity and weight and can be built by additive manufacturing techniques. Their optimization has recently attracted some attention, based on the homogenization method, mostly for compliance minimization. The goal of our two-part work is to extend lattice optimization to stress minimization problems two-dimensionally. The present first part is devoted to the choice of a parametrized periodicity cell that will be used for structural optimization in the second part of our work. In order to avoid stress concentration, we propose a square cell microstructure with a super-ellipsoidal hole instead of the standard rectangular hole often used for compliance minimization. This type of cell is parametrized two-dimensionally by one orientation angle, two semi-axis and a corner smoothing parameter. We first analyse their influence on the stress amplification factor by performing some numerical experiments. Second, we compute the optimal corner smoothing parameter for each possible microstructure and macroscopic stress. Then, we average (with specific weights) the optimal smoothing exponent with respect to the macroscopic stress. Finally, to validate the results, we compare our optimal super-ellipsoidal hole with the Vigdergauz microstructure which is known to be optimal for stress minimization in some special cases.This article is part of the theme issue ‘Topics in mathematical design of complex materials’.

description: Metaballs sind eine Klasse von impliziten Flächen die verwendet werden um organisch aussehende Formen und Flüssigkeiten zu modellieren. Exakte Darstellung von drei-dimensionalen Metaballs wird typischerweise durch Ray-casting erzielt, das jedoch rechenaufwendig ist und nicht für Echtzeitanwendungen geeignet ist. Deshalb wurden verschiedene annähernde Rendering Methoden entwickelt. In dieser Arbeit werden die Grundlagen von Metaballs und Neuralen Netzwerken behandelt, und ein neuer Ansatz um Metaballs durch Deep Learning zu rendern der performant genug für Echtzeitanwendungen ist präsentiert. Dieses System verwendet einen Bild-zu-Bild-Übersetzungs Ansatz. Dafür werden die Metaballs zuerst in einer stark vereinfachten Form in ein Bild gerendert. Dieses Bild dient danach als Input für ein Neurales Netzwerk das Tiefe, Normalen, und Grundfarben-Puffer als Output produziert die anschließend mit einem deferred shading Renderer in ein finales Bild kombiniert werden können.
description: Metaballs are a type of implicit surface that are used to model organic-looking shapes and fluids. Accurate rendering of three-dimensional metaballs is typically done using ray-casting, which is computationally expensive and not suitable for real-time applications, therefore different approximate methods for rendering metaballs have been developed. In this thesis, the foundations of metaballs and neural networks are discussed, and a new approach to rendering metaballs using Deep Learning that is fast enough for use in real-time applications is presented. The system uses an image-to-image translation approach. For that, first the metaballs are rendered using a very simplified representation to an image. This image is then used as input to a neural network that outputs a depth, normal and base color buffer that can be combined using a deferred shading renderer to produce a final image.

Making use of feature of NMR measure and the technology of the second (discrete) Fourier transformation, our theoretical scheme can obtain the spectrum of paring model in principle. We concretely discuss the case in the concerned subspaces of pairing model and then, as an example, give out a simple initial state to get the gap of two the lowest energy levels in the given subspace. The quantum simulation to get more differences of energy levels is able to be discussed similarly.

description: This article gives a brief overview of the popular methods for estimating variance components in linear models and describes several ways to obtain such estimates in Stata for various experimental designs. The article’s emphasis is on using xtmixed to estimate variance components. Prior to Stata 9, loneway could be used to estimate variance components for one-way random-effects models. For other experimental designs, variance components could be computed manually using saved results after anova. The latter approach is viable but requires tedious computations for complicated experimental designs. Instead, as of Stata 9, variance components are easily obtained by using xtmixed.

description: There is no escaping from the fact that most of the time the marāṭhā category includes both the Deccan kṣatrīya and the kuṇbī; though by and large, the users of the label recognize and accept that the two are indeed distinct ‘castes’; Karve calls such an arrangement a ‘caste cluster’. [Karve, 1961 : Hindu Society – An Interpretation, 19] The Deccan kṣatrīya and the kuṇbī are treated as endogamous ‘castes’ within the cluster : most of the time they do not interdine and do not intermarry, but exceptions do occur. As a result there has been significant intermingling between the two groups. According to Karve in successive censuses the word kuṇbī has receded, until at last in the 1941 census the word has all but vanished; the kuṇbī have given their ‘caste’ either as Maratha or as some kind of kṣatrīya (1941 census was the last to register ‘caste’).

We compute the binding energies of the 4He tetramer and of alpha-particle. The well-known linear correlation between the three-body binding energies and the four-body binding energies of these physical systems can be understood as a consequence of the absence of a four-body force at leading order.

description: At its heyday, Kāṭhīyāvāḍ was not just one port; it was a massive port complex from the gulf of Kacca through the Little Rann and the Nāl-Bhāl depression up to the gulf of Khāmbāt. It was the grand entrepôt of the trade with the Near East and Africa. [The Odyssey of Kṣatrīya and Brāmhaṇ, 10 Feb 19] It lay on a new trade corridor between China and Mesopotamia. This corridor entered the Indian sub-continent from the North-East and went along the Brahmaputra-Ganga plain to Kāṭhīyāvāḍ; and thence by sea along the Sind and Makran coast into the Gulf of Oman and further to Tigris - Euphrates basin. [The Mesopotamian Connection, 11 Jul 19]But the glory of Kāṭhīyāvāḍ did not last for long. Sometime around the beginning of the Common Era rising sea submerged Kāṭhīyāvāḍ; the exact time of this could vary significantly, as this region seem to have submerged more than once. [Kṛṣṇa’s Dvārakā, 14 May 17; The Lost Kuśasthaḷī, 21 May 17] When Kāṭhīyāvāḍa was submerged the trade had to move; but its replacement had to be equally massive. What eventually came to be built was a ‘belt’ of ports spanning the entire littoral of Komkan, from Saṁjāṇa in Gujarat (outside modern Daman) to Kuśasthaḷī in Goa. At many of these ‘new port cities’, we find strong cultural and archaeological evidence of cultural continuity between Kāṭhīyāvāḍ and the new homes of Kāṭhīyāvāḍī.

Pollinator-mediated selection and diversity in flowering plants
Creators: name: Sargent, Risa
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the role pollinators have played in the diversification of flowering plants. The extent to which animal pollinators drive the formation of new angiosperm species remains unresolved. Animal pollinators may drive higher rates of diversification because they promote reproductive isolation via specialization on certain floral forms. In Chapter II, using sister group comparisons, I demonstrate that flowering plant lineages possessing monosymmetric (=bilaterally symmetrical) flowers, tend to be more species rich than their radially symmetrical sister lineages. This result supports an important role for pollinator-mediated speciation and indicates that floral morphology plays a key role in angiosperm speciation. The degree to which flowers should evolve to attract one type of pollinator or a suite of pollinators is unclear. In Chapter III, I develop a population genetics model that examines the effects of local species richness on the evolution of pollinator specialization. The model predicts that local species richness plays a role in determining whether or not plants evolve to specialize on one type of pollinator. This model connects the number of species competing for pollinator attention and the probability of a plant receiving conspecific pollen to show that generalist flowers are more likely to evolve when a species is numerically dominant. In addition to morphological diversity, angiosperm species also exhibit a wide diversity of mating strategies. In Chapter IV, I develop a population genetic model to explore the evolutionary forces that contribute to the evolution of dichogamy, a mating strategy whereby pollen dispersal and stigma receptivity are separated in time. The model suggests that factors such as anther-stigma interference and inbreeding depression tend to select for dichogamy, while factors such as the fitness advantage of selffertilization and selection to match the timing of ovule and pollen production tend to select against dichogamy. Lastly, In Chapter V, I test the hypothesis that pollination mode (i.e., wind or animal) is evolutionarily correlated with the form of dichogamy using a maximum likelihood program designed to detect correlated trait evolution on phylogenetic trees. The results suggest that protandry and protogyny have evolved in response to different modes of pollination; specifically, in animal-pollinated species flowers evolve protandry, while in wind-pollinated species flowers evolve protogyny.

description: The cosmic microwave background (CMB) has been a treasure trove for cosmology. Over the next decade, current and planned CMB experiments are expected to exhaust nearly all primary CMB information. To further constrain cosmological models, there is a great benefit to measuring signals beyond the primary modes. Rayleigh scattering of the CMB is one source of additional cosmological information. It is caused by the additional scattering of CMB photons by neutral species formed during recombination and exhibits a strong and unique frequency scaling ($\propto ν^4$). We will show that with sufficient sensitivity across frequency channels, the Rayleigh scattering signal should not only be detectable but can significantly improve constraining power for cosmological parameters, with limited or no additional modifications to planned experiments. We will provide heuristic explanations for why certain cosmological parameters benefit from measurement of the Rayleigh scattering signal, and confirm these intuitions using the Fisher formalism. In particular, observation of Rayleigh scattering allows significant improvements on measurements of $N_{\rm eff}$ and $\sum m_ν$.

description: Exploring the significant impacts of topological charge on the holographic phase transitions and conductivity we start from an Einstein - Maxwell system coupled with a charged scalar field in Anti - de Sitter spacetime. In our set up, the corresponding black hole (BH) is chosen to be the topological AdS one where the pressure is identified with the cosmological constant. Our numerical computation shows that the process of condensation is favored at finite topological charge and, in particular, the pressure variation in the bulk generates a mechanism for changing the order of phase transitions in the boundary: the second order phase transitions occur at pressures higher than the critical pressure of the phase transition from small to large BHs while they become first order at lower pressures. This property is confirmed with the aid of holographic free energy. Finally, the frequency dependent conductivity exhibits a gap when the phase transition is second order and when the phase transition becomes first order this gap is either reduced or totally lost.

description: We consider the unoriented two-dimensional Abelian sandpile model on the half-plane with open and closed boundary conditions, and relate it to the boundary logarithmic conformal field theory with central charge c=-2. Building on previous results, we first perform a complementary lattice analysis of the operator effecting the change of boundary condition between open and closed, which confirms that this operator is a weight -1/8 boundary primary field, whose fusion agrees with lattice calculations. We then consider the operators corresponding to the unit height variable and to a mass insertion at an isolated site of the upper half plane and compute their one-point functions in presence of a boundary containing the two kinds of boundary conditions. We show that the scaling limit of the mass insertion operator is a weight zero logarithmic field.

title: Impermanent development and the pursuit of permanence: mobilising marginalisation and uncertainty towards a rightful share of Kenya’s oil

description: What happens when the historically marginalised part of a country becomes overnight a reservoir of potential national wealth? In 2012, commercially viable crude oil deposits were confirmed in Turkana County, Kenya, home to some of East Africa’s few mobile pastoralists. This thesis examines the dynamics of resource extraction that unfolded since then, including promises of development and social inclusion for this hitherto relegated region. Oil is unusual in that it is a highly lucrative commodity with tremendous economic potential. In recent years, there has been a proliferation of policies around ‘ethical extraction’ and the requirement that oil companies need to leave communities better off than they found them. This thesis argues that despite the social performances of global best practices, oil has actually exacerbated the precarious living conditions in the county instead of providing the stability that was promised. The net result is a community that lives in a cycle of impermanence characterised by temporary jobs, incomplete infrastructure, and inconsistent development projects. This has resulted from a combination of the fragile and indeterminate nature of oil itself, the technical nature of jobs in the extractives industry, the unequal power relations between industry and government, and the ambiguous ethical codes that appear to breed secrecy more than accountability and transparency. The thesis includes an analysis of Turkana’s rapidly shifting position within Kenyan political and economic structures; an account of the redefinition of entitlements to resources and revenues and how this has shaped local political, socioeconomic, and ethnic identities; and a discussion of how the Kenyan state, corporate actors, third-sector agencies, and local populations are seeking to design the prospective future with oil. It develops an original analytical framework in order to explore how histories of marginalisation and uncertainty shape the processes of natural resource development. Anthropologists have long examined the relationship between pastoral societies and modernisation, particularly their exclusion from national social compacts and political life. This study aims to contribute anthropological perspectives on the extractive industries by investigating the uneven distribution of early oil benefits and the competing responsibilities for constituting and securing a rightful share of the profits. This involves paying attention to the power relations and governance techniques that perpetuate marginalisation and to the internal dynamics of livelihood struggles and social relations in pastoral areas.

description: This paper presents a command, glst, for trend estimation across different exposure levels for either single or multiple summarized case–control, incidence-rate, and cumulative incidence data. This approach is based on constructing an approximate covariance estimate for the log relative risks and estimating a corrected linear trend using generalized least squares. For trend analysis of multiple studies, glst can estimate fixed- and random-effects metaregression models.

description: Background: People with severe speech and motor impairment (SSMI) often uses a technique called eye pointing to communicate with outside world. One of their parents, caretakers or teachers hold a printed board in front of them and by analyzing their eye gaze manually, their intentions are interpreted. This technique is often error prone and time consuming and depends on a single caretaker. Objective: We aimed to automate the eye tracking process electronically by using commercially available tablet, computer or laptop and without requiring any dedicated hardware for eye gaze tracking. The eye gaze tracker is used to develop a video see through based AR (augmented reality) display that controls a robotic device with eye gaze and deployed for a fabric printing task. Methodology: We undertook a user centred design process and separately evaluated the web cam based gaze tracker and the video see through based human robot interaction involving users with SSMI. We also reported a user study on manipulating a robotic arm with webcam based eye gaze tracker. Results: Using our bespoke eye gaze controlled interface, able bodied users can select one of nine regions of screen at a median of less than 2 secs and users with SSMI can do so at a median of 4 secs. Using the eye gaze controlled human-robot AR display, users with SSMI could undertake representative pick and drop task at an average duration less than 15 secs and reach a randomly designated target within 60 secs using a COTS eye tracker and at an average time of 2 mins using the webcam based eye gaze tracker.

Generalized ordered logit/partial proportional odds models for ordinal dependent variables

description: This article describes the gologit2 program for generalized ordered logit models. gologit2 is inspired by Vincent Fu’s gologit routine (Stata Technical Bulletin Reprints 8: 160–164) and is backward compatible with it but offers several additional powerful options. A major strength of gologit2 is that it can fit three special cases of the generalized model: the proportional odds/parallel-lines model, the partial proportional odds model, and the logistic regression model. Hence, gologit2 can fit models that are less restrictive than the parallel-lines models fitted by ologit (whose assumptions are often violated) but more parsimonious and interpretable than those fitted by a nonordinal method, such as multinomial logistic regression (i.e., mlogit). Other key advantages of gologit2 include support for linear constraints, survey data estimation, and the computation of estimated probabilities via the predict command.

description: Many underutilized crops are characterized by high nutritional quality and resilience to abiotic stress, but their yield and agronomic properties are significantly lower compared to major crops. The last decades of genomic, physiological, and population genetic research provide the opportunity to transfer methods to minor crops to accelerate their improvement if knowledge is effectively shared between disciplines. Grain amaranth is an ancient nutritious pseudocereal from the Americas that is regaining importance due to its high protein content and favorable amino acid and micronutrient composition. To effectively combine genomic and population genetic information with molecular genetics, plant physiology, and use it for interdisciplinary research and crop improvement, an intuitive interaction for scientists across disciplines is essential. Here, we present PopAmaranth, a population genetic genome browser, which provides an accessible representation of the geneticv ariation of the three grain amaranth species (A. hypochondriacus, A. cruentus, and A. caudatus) and two wild relatives (A.hybridus and A. quitensis) along theA. hypochondriacus reference sequence. We provide population scale diversity and selection analysis from whole-genome sequencing data of 88 curated genetically and taxonomically unambiguously classified accessions. We incorporate the domestication history of the three grain amaranths to provide an evolutionary perspective for candidate genes. We show that genetic diversity in the water stress-related MIF1 gene declined during amaranth domestication and provide evidence for converged saponin reduction between amaranth and quinoa. These examples show that our tool enables the detailed study of individual genes, provides target regions for breeding efforts, and can enhance the interdisciplinary integration of population genomic findings across species.

description: El objetivo de este trabajo es analizar cómo inciden los factores biológicos, técnicos, medioambientales y económicos en la rentabilidad de las empresas de piscicultura. Para ello se contrasta, con técnicas de análisis multivariante, un modelo empírico utilizando datos de empresas españolas de cría de dorada y lubina en el periodo 2005/2007. Los resultados muestran cómo los aspectos técnico-biológicos pierden importancia a medida que se estandarizan los procesos productivos, mientras que se incrementa la relevancia de los aspectos medioambientales y económicos.
