description: In this paper we present an arbitrary-order fully discrete Stokes complex on general polyhedral meshes. We enriche the fully discrete de Rham complex with the addition of a full gradient operator defined on vector fields and fitting into the complex. We show a complete set of results on the novelties of this complex: exactness properties, uniform Poincaré inequalities and primal and adjoint consistency. The Stokes complex is especially well suited for problem involving Jacobian, divergence and curl, like the Stokes problem or magnetohydrodynamic systems. The framework developed here eases the design and analysis of scheme for such problems. Schemes built that way are nonconforming and benefit from the exactness of the complex. We illustrate with the design and study of a scheme to solve the Stokes equations and validate the convergence rates with various numerical tests.

title: Parenting Behaviors Related to Young Adult Depressive Symptomology
Creators: name: Abramson, Rebecca D.
Publisher: name: Old Dominion university
Year: 2001

description: arental stress, hostility, warmth, acceptance, amount of control, and overall security of parent-child attachment appears to influence childhood and adult adjustment. Several relationships have been found between parenting style and the emotional and psychological well being of children and adolescents (e.g., Baumrind, 1967, 1971; Parker, 1979a, 1979b; Ge, Conger, Lorenz, & Simons, 1994; Ge, Best, Conger, & Simons, 1996). The present study examined the effects of perceived parenting styles on young adults' reported psychological distress and depressive symptomology. Participants viewed both mothers and fathers as equally attentive, supportive, and controlling, while viewing mothers as slightly more caring. However, participants' perceptions of their mothers' parenting practices showed strong relationships to respondents' reported depressive symptomology and stress levels while their perceptions of their fathers showed weak relationships to stress and depressive symptomology.

Parenting style was assessed using the Parental Bonding Instrument (Parker, Tupling, & Brown, 1979) and the Children's Report of Parenting Behavior Inventory (Schaefer, 1965). Psychological distress and level of depressive symptomology were measured with the Symptom-Checklist-90-Revised (Derogatis, 1983) and the Center for Epidemiologic Studies-Depression-Scale (Radloff; 1977).

description: In this study mechanical fatigue behaviour of different types of Cu metallization film stacks (consisting of Si/SiO2/TiW/Cu) on Si substrates was investigated in the high cycle fatigue regime at room temperature. The influence of thickness, grain size and texture as well as the composition of the diffusion barrier on the deformation behaviour of Cu metallization layers in the thickness range of 5 µm to 20 µm was studied. The samples, which consisted of Cu-metallized Si strips were subjected to symmetrical tension - compression fatigue loading by using an ultrasonic resonance fatigue testing systems working at 36kHz at room temperature. Systematic investigations of surface degradation and fatigue damage in the films showed distinct slip band formation in preferentially oriented grains. Evaluation of fatigue life and the degree of damage was based on the determination of the slip band density as a function of loading cycles as measured by means of optical microscopy. The degree of damage was found to be highly dependent on film thickness, grain orientation and grain size. Moreover it was found that there exists a trend between the adhesion strength of Si/diffusion barrier/Cu and the degree of surface damage during the high frequency fatigue loading (higher adhesion strength of the diffusion barriers to the silicon substrate resulted in a higher degree of surface deformation of the Cu films). This result may be used as a measure for the evaluation of the dynamic adhesion response of thin film stacks on Si substrates. Furthermore, in order to study the effect of constraint on the lifetime and cyclic deformation behavior of the Cu films, free standing miniaturized bar shaped fatigue specimens were prepared by chemical removal of the silicon substrate. Fatigue life curves (Wöhler curves) were determined by using an ultrasonic fatigue system working at 20kHz and a special set-up suitable for testing of free standing miniaturized specimens. The comparison of fatigue tests on free standing Cu bars with Cu film stacks of the same thickness and microstructure showed that cyclic induced plastic deformation is noticeably suppressed in constraint films. Cu bars showed a higher density of deformed grains, with rougher and broader extrusions compared to the features observed in Cu films on a silicon substrate. The fatigue life curve of the free standing Cu bars covered a stress range of 15-25MPa in the high cycle regime (>106), while early stages of slip band formation on the surface of Cu metallization on Si was observed first at stress levels in the range of 72MPa. The results of this study are a contribution to understanding the mechanical fatigue response of constrained metallization films on substrates and provides a new efficient methodology.
Foreign trade elasticities in centre-periphery models of growth and development

Publisher: name: PSL Quarterly Review
Year: 2013
Subjects: subject: Growth, balance of payments, income elasticity of demand, imports, exports
subject: F14, F32

description: The Author looks at the difference in growth rates among countries and argues that they can be traced to the strength of the balance of payments position, determined largely by the propensity to export relative to the propensity to import. Relative growth performance, thus, can be understood by looking to income elasticities of demand for exports and imports. This insight into the process of income determination in open economies, found in Harrod as well as in the literature on economic development, is developed through so-called centre-periphery models of growth and development. However, their essential conclusions were already contained in the early classic papers. The author concentrates on three of them (Prebisch, Seers, Kaldor) to argue that a country’s growth rate relative to another’s can be approximated by the ratio of its income elasticity of demand for exports to its income elasticity of demand for imports.

description: We study logarithmic Voronoi cells for linear statistical models and partial linear models. The logarithmic Voronoi cells at points on such model are polytopes. To any $d$-dimensional linear model inside the probability simplex $Δ_{n-1}$, we can associate an $n\times d$ matrix $B$. For interior points, we describe the vertices of these polytopes in terms of co-circuits of $B$. We also show that these polytopes are combinatorially isomorphic to the dual of a vector configuration with Gale diagram $B$. This means that logarithmic Voronoi cells at all interior points on a linear model have the same combinatorial type. We also describe logarithmic Voronoi cells at points on the boundary of the simplex. Finally, we study logarithmic Voronoi cells of partial linear models, where the points on the boundary of the model are especially of interest.

title: Initial value problems in general relativity
Creators: name: Gunasekaran, Sharmila
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: The initial value formulation viewpoint is one of the main foci of research in general relativity. This thesis establishes results for two problems pertinent to it. In the first of the problems which form the contents of Chapters 3 and 4, the focus is on a class of five dimensional stationary asymptotically flat spacetimes. These naturally arise in high energy physics as possible microstates of black hole spacetimes. In Chapter 3, several spacetimes with non-trivial topology in the domain of outer communication are considered, of which the soliton spacetime is one such example. The mass variation formula previously established for such spacetimes is used to compute energy, angular momenta and charge for these spacetimes. It is shown that regularity is essential for the formula relating them to hold. In Chapter 4, the decay of the wave equation in a family of soliton spacetimes is studied and a slow decay rate is established, hinting at nonlinear instability. The second problem is establishing a horizon-based initial boundary value formulation with the goal of studying the near-horizon spacetime. The problem is addressed in the setting of four-dimensional general relativity. In Chapter 5, we establish that data specified on the horizon and a future null boundary determine the near horizon geometry and illustrate this for spherically symmetric spacetimes with a massless scalar field. In Chapter 6 we conclude with directions for future research.

description: We demonstrate that flavour-changing neutral currents in the top sector, mediated by leptophilic scalars at the electroweak scale, can easily arise in scenarios of new physics, and in particular in composite Higgs models. We moreover show that such interactions are poorly constrained by current experiments, while they can be searched for at the LHC in rare top decays and, more generally, in the channels $pp\to tS(S)+j$, with $S\to\ell^+\ell^-$. We provide dedicated analyses in this respect, obtaining that cut-off scales as large as $Λ\sim$ 90 TeV can be probed with an integrated luminosity of $\mathcal{L} = 150$ fb$^{-1}$.

description: Sentiment analysis seeks to identify the viewpoint(s) underlying a text span; an example application is classifying a movie review as "thumbs up" or "thumbs down". To determine this sentiment polarity, we propose a novel machine-learning method that applies text-categorization techniques to just the subjective portions of the document. Extracting these portions can be implemented using efficient techniques for finding minimum cuts in graphs; this greatly facilitates incorporation of cross-sentence contextual constraints.

description: The algorithms and the interactions facilitated by online platforms have been used by radical groups to recruit vulnerable individuals to their cause. This has resulted in the sharp growth of violent events and deteriorating online discourse. The Manosphere, a collection of radical anti-feminist communities, is one such group which has attracted attention due to their rapid growth and increasingly violent real world outbursts. In this paper, we examine the social engagements between Reddit users who have participated in feminist discourse and the Manosphere communities on Reddit to understand the process of development of traits associated with the adoption of extremist ideologies. By using existing research on the psychology of radicalization we track how specific types of social engagement with the Manosphere influence the development of traits associated with radicalization. Our findings show that: (1) participation, even by the simple act of joining the Manosphere, has a significant influence on the language and outlook traits of a user, (2) Manosphere elites are extremely effective propagators of radical traits and cause their increase even outside the Manosphere, and (3) community perception can heavily influence a user's behavior. Finally, we examine how our findings can help draft community and platform moderation policies to help mitigate the problem of online radicalization.

The type of activities engaged in and the causes of this growth in business are studied, in addition to their general welfare effects. It is concluded that both developments in technology and a desire to escape Canadian regulations and taxation have caused this growth. It is argued that resultant inefficiencies have entered banking practice, which should be rectified by the payment of interest on banks' compulsory reserves with the Bank of Canada.

description: Quantum support vector machines employ quantum circuits to define the kernel function. It has been shown that this approach offers a provable exponential speedup compared to any known classical algorithm for certain data sets. The training of such models corresponds to solving a convex optimization problem either via its primal or dual formulation. Due to the probabilistic nature of quantum mechanics, the training algorithms are affected by statistical uncertainty, which has a major impact on their complexity. We show that the dual problem can be solved in $O(M^{4.67}/\varepsilon^2)$ quantum circuit evaluations, where $M$ denotes the size of the data set and $\varepsilon$ the solution accuracy compared to the ideal result from exact expectation values, which is only obtainable in theory. We prove under an empirically motivated assumption that the kernelized primal problem can alternatively be solved in $O(\min \{ M^2/\varepsilon^6, \, 1/\varepsilon^{10} \})$ evaluations by employing a generalization of a known classical algorithm called Pegasos. Accompanying empirical results demonstrate these analytical complexities to be essentially tight. In addition, we investigate a variational approximation to quantum support vector machines and show that their heuristic training achieves considerably better scaling in our experiments.

This is the first analytic calculation of a three-parameter event shape observable, which provides valuable data for various studies ranging from conformal field theories to jet substructure. The associated class of functions define a new type of single-valued polylogarithms characterized by 16 alphabet letters, which manifest a $D_6 \times Z_2$ dihedral symmetry of the event shape. With the unexplored simplicity in the perturbative structure of EEEC, all kinematic regions including collinear, squeezed and coplanar limits are now available.

description: Piero Sraffa is widely regarded as the greatest Italian economist and one of the greatest economists of all time. And yet, some have argued that Sraffa’s work has not penetrated deeply into the consciousness of the economic profession. The present work responds to this view by drawing attention to Sraffa’s contribution to the reconstruction of political economy, and, more generally, to his influence on modern culture. The author demonstrates how Sraffa’s influence has been felt in different fields: not only in economics, but also that of philosophy and politics. JEL: B24, B31, E11

description: We calculate the critical density of the zero-temperature, first-order ferromagnetic phase transition in n-doped GaAs/AlGaAs quantum wells. We find that the existence of the ferromagnetic transition is dependent upon the choice of well width. We demonstrate rigorously that this dependence is governed by the interplay between different components of the exchange interaction and that there exists an upper limit for the well width beyond which there is no transition. We predict that some narrow quantum wells could exhibit this transition at electron densities lower than the ones that have been considered experimentally thus far. We use a screened Hartree-Fock approximation with a polarization-dependent effective mass, which is adjusted to match the critical density predicted by Monte Carlo calculations for the two-dimensional electron gas.

description: The nature of the interaction between galaxies and the intergalactic medium (IGM) is one of the most fundamental problems in astrophysics. The accretion of gas onto galaxies provides fuel for star formation, while galactic winds transform the nearby IGM in a number of ways. One exciting technique to study this gas is through the imaging of hydrogen Lyman-alpha emission. We use cosmological simulations to study the Lyman-alpha signals expected from the growth of cosmic structure from z=0-5. We show that if dust absorption is negligible, recombinations following the absorption of stellar ionizing photons dominate the total Lyman-alpha photon production rate. However, galaxies are also surrounded by "Lyman-alpha coronae" of diffuse IGM gas. These coronae are composed of a combination of accreting gas and material ejected from the central galaxy by winds. The Lyman-alpha emission from this phase is powered by a combination of gravitational processes and the photoionizing background. While the former dominates at z~0, collisional excitation following photo-heating may well dominate the total emission at higher redshifts. The central regions of these systems are dense enough to shield themselves from the metagalactic ionizing background; unfortunately, in this regime our simulations are no longer reliable. We therefore consider several scenarios for the emission from the central cores, including one in which self-shielded gas does not emit at all. We show that the combination of star formation and cooling IGM gas can explain most of the observed "Lyman-alpha blobs" at z~3, with the important exception of the largest sources. On the other hand, except under the most optimistic assumptions, cooling IGM gas cannot explain the observations on its own.

Freshwater fish assemblage patterns and risks posed by acidic deposition in northeastern British Columbia
Creators: name: Murray, Sonia Bennett.
Publisher: name: University of British Columbia
Year: 2011

description: In order to manage and protect natural resources it is important to understand local ecological processes and to assess potential risks. I studied the effects of environment on fish assemblage structure and assessed the potential risk of acidic deposition from oil and gas development in northeastern British Columbia (BC) in order to inform future management decisions. This project was part of a cumulative impact assessment project initiated by Treaty #8 First Nations in northeastern BC. They are concerned that recent rapid development in the area may be degrading the environment and infringing upon their rights. I used canonical correspondence analysis to relate environmental variables to patterns in fish assemblage structure at local and regional scales. At the local scale I compared low and high gradient watershed groups in the northern and southern portion of the study area and found that a unique set of variables related to local habitat features in each watershed group best accounted for variation in fish assemblage structure. At the regional scale two gradients best explained patterns in species distribution and abundance. The strongest gradient was correlated with temperature and the second gradient was correlated with stream width, boulder cover and in-stream vegetation cover. These patterns correspond with patterns found in other studies on fish assemblage structure, showing that scale is an important factor in determining the effect of environmental variables on fish and that temperature plays an important role in determining regional species distribution. I used soil maps to predict the potential sensitivity of different areas to acidic deposition, supported by water sampling and fish surveys in the field. In most areas of northeastern BC fish are not at risk from acidification because the ground water is generally quite alkaline and able to buffer incoming acidity. An area north of Fort St. John with organic soils, however, has quite acidic streams (pH 5-6.5) and may be sensitive to acidic deposition. The sensitivity of this area had not been recognized in previous studies of acidic deposition in BC. Further study will be necessary to better delineate the area and the level of sensitivity.

description: Deep learning models for medical image segmentation can fail unexpectedly and spectacularly for pathological cases and images acquired at different centers than training images, with labeling errors that violate expert knowledge. Such errors undermine the trustworthiness of deep learning models for medical image segmentation. Mechanisms for detecting and correcting such failures are essential for safely translating this technology into clinics and are likely to be a requirement of future regulations on artificial intelligence (AI). In this work, we propose a trustworthy AI theoretical framework and a practical system that can augment any backbone AI system using a fallback method and a fail-safe mechanism based on Dempster-Shafer theory. Our approach relies on an actionable definition of trustworthy AI. Our method automatically discards the voxel-level labeling predicted by the backbone AI that violate expert knowledge and relies on a fallback for those voxels. We demonstrate the effectiveness of the proposed trustworthy AI approach on the largest reported annotated dataset of fetal MRI consisting of 540 manually annotated fetal brain 3D T2w MRIs from 13 centers. Our trustworthy AI method improves the robustness of a state-of-the-art backbone AI for fetal brain MRIs acquired across various centers and for fetuses with various brain abnormalities.

description: This paper considers outdoor terrain mapping using RGB images obtained from an aerial vehicle. While feature-based localization and mapping techniques deliver real-time vehicle odometry and sparse keypoint depth reconstruction, a dense model of the environment geometry and semantics (vegetation, buildings, etc.) is usually recovered offline with significant computation and storage. This paper develops a joint 2D-3D learning approach to reconstruct a local metric-semantic mesh at each camera keyframe maintained by a visual odometry algorithm. Given the estimated camera trajectory, the local meshes can be assembled into a global environment model to capture the terrain topology and semantics during online operation. A local mesh is reconstructed using an initialization and refinement stage. In the initialization stage, we estimate the mesh vertex elevation by solving a least squares problem relating the vertex barycentric coordinates to the sparse keypoint depth measurements. In the refinement stage, we associate 2D image and semantic features with the 3D mesh vertices using camera projection and apply graph convolution to refine the mesh vertex spatial coordinates and semantic features based on joint 2D and 3D supervision. Quantitative and qualitative evaluation using real aerial images show the potential of our method to support environmental monitoring and surveillance applications.

Why development aid?

Subjects: subject: Aid, exports, subsidised loans, private foreign investment, trade
subject: F21, F35

description: It has become common practice for both bilateral donors and multilateral aid agencies to make loans to developing countries below the commercial rate of interest. One obvious reason for this is the competition for exports, which can lead to subsidised credits in the hope that export sales of manufactured products or sales of surplus agricultural commodities are thereby promoted. The boundaries become a bit blurred when subsidised loans are given for infrastructure that makes private foreign investment more profitable, or loans to promote benefits from trade in the long-term. The present work, however, focuses on loans without any clear commercial qui pro quo. The author presents five arguments. JEL: F21, F35

Subjects: subject: Astrophysics (astro-ph)

description: In this review, I survey our current understanding of how the very first stars in the universe formed, with a focus on three main areas of interest: the formation of the first protogalaxies and the cooling of gas within them, the nature and extent of fragmentation within the cool gas, and the physics -- in particular the interplay between protostellar accretion and protostellar feedback -- that serves to determine the final stellar mass. In each of these areas, I have attempted to show how our thinking has developed over recent years, aided in large part by the increasing ease with which we can now perform detailed numerical simulations of primordial star formation. I have also tried to indicate the areas where our understanding remains incomplete, and to identify some of the most important unsolved problems.

description: A decade has elapsed since our country joined the European Union. It is a historical period. In 2004 – when Hungary became the member of the EU – the world surrounding Hungary went through a transformation. Have we achieved our goals? Are we disappointed? The answers to these questions are limited in their scope today. However, the author is convinced that the feeling of unsatisfaction is not the result of our EU membership.

description: The problem of nutrition security is getting worse in Africa, due to increasing population growth and poor progress in efforts directed at reducing food insecurity in many countries in the continent. The paper undertook an assessment of the food security situation and food consumption pattern in rural households in Ogun state, Nigeria. A multistage sampling technique was used to select 260 rural households from whom data were collected through structured questionnaire. The tools of analysis were descriptive statistics and food security index. The former described the consumption pattern, and households’ sources of food availability, while the latter was used to analyse the food security situation. The result of the rural households’ consumption pattern reveals that the rural households derived more of their energy from carbohydrates at the expense of other classes of food items. The result also shows that majority (75.5%) obtained their food through their own production and supplemented same with food purchased from the market to meet up with their family needs. Based on the recommended daily calorie intake (R) of 2,470 kcal, 59.6% of the rural households were food insecure while 40.4% were food secure. The calculated head count ratio (H) for the food insecure households was 0.6, confirming that almost 60% of households in the study area were food insecure. For secure households, the head count ratio (H) was 0.4, further confirming that only about 40% of households in the study area were food secure. The shortfall index and surplus index were 0.2787 and 0.3498 respectively, meaning that the energy requirement was less by about 27 percent and in excess of 34 percent for the food insecure and food secure households. The paper recommends that while enhancing production of arable crops - roots, tubers and cereals, a sensible balance of tilting towards meeting the requirements in the consumption of animal protein/legume, fats/oils, fruits and vegetables must be maintained to ensure food security. This policy thrust could be enhanced through mass education.

description: Social entrepreneurship, as a field for research and scientific disputes between scholars and practitioners, it still remains a novel investigation area, as far as new opportunities, challenges, business approaches and concepts appear into the modern world and competitive market. This paper puts emphasis on social framework behind the development of social businesses in Moldova. Moreover, it presents the grass-root state of readiness of existing small and medium – sized enterprises from Moldova to undertake the leap towards the new kind of economy and different organizational approaches. The paper provides a content analysis of specific literature on social entrepreneurship, with particular emphasis on general perception of the small holders and small and medium – sized enterprises on social business. A total number of 593 small and medium – sized enterprises and individuals participated to organized interviews. The survey results show that 66% of the respondents are not acknowledged with social entrepreneurship concept and functionality. From those (34%) who are informed about the topic, most of them are actual young entrepreneurs. Additionally, young entrepreneurs, respondents, wouldn’t reinvest their profit for social mission (73%). Unlike young entrepreneurs, individuals would reinvest their profit in social missions, in case they have a business. These findings suggest that, in the society there is a lack of general understanding on social entrepreneurship. The author also found out that, the general perception regarding social problems is mostly assigned to public authorities instead of enterprises. Moreover, the research results show that the absence of a clear mechanism which would raise public awareness regarding social problems and social capital, affects the active implication of community stakeholders into the societal problems.

Nonlinear Photonic Crystals: IV. Nonlinear Schrodinger Equation Regime
Creators: name: Babin, Anatoli

Year: 2004
Subjects: subject: Mathematical Physics (math-ph)

description: We study here the nonlinear Schrodinger Equation (NLS) as the first term in a sequence of approximations for an electromagnetic (EM) wave propagating according to the nonlinear Maxwell equations (NLM). The dielectric medium is assumed to be periodic, with a cubic nonlinearity, and with its linear background possessing inversion symmetric dispersion relations. The medium is excited by a current $\mathbf{J}$ producing an EM wave. The wave nonlinear evolution is analyzed based on the modal decomposition and an expansion of the exact solution to the NLM into an asymptotic series with respect to some three small parameters $α$, $β$ and $\varrho $. These parameters are introduced through the excitation current $\mathbf{J}$ to scale respectively (i) its amplitude and consequently the magnitude of the nonlinearity; (ii) the range of wavevectors involved in its modal composition, with $β^{-1}$ scaling its spatial extension; (iii) its frequency bandwidth, with $\varrho ^{-1}$ scaling its time extension. We develop a consistent theory of approximations of increasing accuracy for the NLM with its first term governed by the NLS. We show that such NLS regime is the medium response to an almost monochromatic excitation current $\mathbf{J} $. The developed approach not only provides rigorous estimates of the approximation accuracy of the NLM with the NLS in terms of powers of $α$, $β$ and $\varrho $, but it also produces new extended NLS (ENLS) equations providing better approximations. Remarkably, quantitative estimates show that properly tailored ENLS can significantly improve the approximation accuracy of the NLM compare with the classical NLS.

Subjects: subject: Federal Reserve, FED, policy, interest rates, federal funds rate
subject: E58, E43

description: The article considers the change in the federal reserve instruments that occurred since October 1979. Before then, the FED used bank reserves to establish an interest rate that would result in the desired level of the money stock. After 1979 the FED replaced the federal funds rate as its control variable with the volume of bank reserves. In principal, provided the will to adjust interest rates when the money stock is off target exists, two policies show little difference. Critics of the Fed’s policy prior to 1979 often confuse principal with practice. Then, Fed policy was closer to pegging the federal funds rate than to using it as a control over the quantity of money. JEL: E58, E43
