Cultural variations in mothers’ attributions : influence of child attention-deficit/hyperactivity disorder
Creators: name: Mah, Janet W. T.
Publisher: name: University of British Columbia
Year: 2010

description: The attributions made by Chinese immigrant and Euro-Canadian mothers regarding the causes of child prosocial and problem behaviors exhibited by children with and without Attention- Deficit/Hyperactivity Disorder (ADHD) were investigated. The attributions of 51 mothers of 5-to 9-year-old boys were elicited using audio-taped scenarios of child behavior. In one-half of the scenarios, the child was described as having ADHD. Overall, mothers attributed less responsibility to the child for problem behaviors when the child was described as having an ADHD diagnosis than when the child was described as not having any behavior disorders. Furthermore, in comparison to Euro-Canadian mothers, Chinese immigrant mothers saw the child as less responsible for prosocial behavior. In general, mothers attributed the child’s prosocial behaviors more than problem behaviors to parental factors, and also attributed the behavior of children who were described as not having any behavior disorders more to parental factors compared to the behavior of children labeled with ADHD. Findings from this study have implications for gaining a better understanding of the cultural uniqueness and similarities of maternal attitudes regarding ADHD.

description: The aim of the paper was to present the value of rural and urban household consumer goods and services expenditures under changes of their income. Consumption expenditures per capita in households on rural areas are lower than in urban areas. The highest increase of consumption expenditures as a result of per capita disposable income increase was observed in expenditures on: communication, furnishing, household equipment and routine maintenance of the house and food and non-alcoholic beverages both in rural and urban households. In urban households with an increase of per capita income spending on recreation and culture, pocket money and transport increased while in rural household expenditure on miscellaneous goods and services increased.

description: An extensive phytochemical study of a foliose lichen from Indonesia, Parmelia cetrata, resulted in the successful isolation of 13 phenol and depside derivatives (1–13) including the previously unreported depsides 3′-hydroxyl-5′-pentylphenyl 2,4-dihydroxyl-6-methylbenzoate (7), 3′-hydroxyl-5′-propylphenyl 2,4-dihydroxyl-6-methylbenzoate (8) and 3′-hydroxyl-5′-methylphenyl 2-hydroxyl-4-methoxyl-6-propylbenzoate (9). The anti-infective activity of isolated compounds was evaluated against the gram-negative bacterium Aliivibrio fischeri and the nematode Caenorhabditis elegans. 2,4-Dihydroxyl-6-pentylbenzoate (5) and lecanoric acid (6) induced growth inhibition of A. fischeri with inhibition values of 49% and 100% at a concentration of 100 µM, respectively. The antibacterial activity might be due to their free carboxyl group. A phenolic group at C4 also contributed to the antimicrobial activity of the depsides as shown for compounds 7 and 8, which caused 89% and 96% growth inhibition at 100 µM, respectively. Lecanoric acid (6) in addition possesses significant anthelmintic effects causing 80% mortality of C. elegans at 100 µg/mL.

description: Finding efficient ways of manipulating magnetic bits is one of the core goals in spintronic research. Electrically-generated spin-orbit torques (SOTs) are good candidates for this and the search for materials capable of generating highly-efficient SOTs has gained a lot of traction in the recent years. While antiferromagnet/ferromagnet bilayer structures have been employed extensively for passive applications, e.g. by using exchange bias fields, their active properties are not yet widely employed. Here we show the presence of large interfacial SOTs in bilayer of a ferromagnet and the two-dimensional layered antiferromagnetic insulator NiPS$_3$. We observe a large in-plane damping-like interfacial torque, showing a torque conductivity of $σ_\mathrm{DL} \approx 1 \times 10^{5} \mathrm{(\frac{\hbar}{2e}) /(Ωm)}$ even at room temperature, comparable to the best devices reported in the literature for standard heavy-metal-based and topological insulators-based devices. Additionally, our devices also show an out-of-plane field-like torque arising from the NiPS$_3$/ferromagnet interface, further indicating the presence of an interfacial spin-orbit coupling in our structures. Temperature-dependent measurements reveal an increase of the SOTs with a decreasing temperature below the Néel temperature of NiPS$_3$ ($T_N \approx 170 \mathrm{K}$), pointing to a possible effect of the magnetic ordering on our measured SOTs. Our findings show the potential of antiferromagnetic insulators and two-dimensional materials for future spintronic applications.

description: We present a method to calculate many-body states of interacting carriers in million atom quantum nanostructures based on atomistic tight-binding calculations and a combination of iterative selection of configurations and perturbation theory. This method enables investigations of large excitonic complexes and multi-electron systems with near full configuration interaction accuracy, even though only a small subspace of the full many-body Hilbert space is sampled, thus saving orders of magnitudes in computational resources. Important advantages of this method are that the convergence is controlled by a single parameter, the threshold, and that ground and excited states can be treated on an equal footing. We demonstrate the extreme efficiency of the method by numerical studies of complexes composed of up to 13 excitons, which requires filling of states up to the fourth electronic shell. We find that the method generally converges fast as a function of the threshold, profiting from a significant enhancement due to the perturbative corrections. The role of the choice of single-particle basis states is discussed. It is found that the algorithm converges faster in the Hartree-Fock basis only for highly charged systems, where Coulomb repulsion dominates. Finally, based on the observation that second order perturbative energy corrections only depend on off-diagonal elements of the many-body Hamiltonian, we present a way to accurately calculate many-body states that requires only a relatively small number of Coulomb matrix elements.

description: An explicit evaluation of the spin asymmetry of the deuteron and the associated GDH sum rule is presented which includes disintegration, single and double pion and eta production. For the GDH integral a large cancellation is found between the disintegration channel and the meson production channels. Furthermore, first results for the contribution of the disintegration channel to the generalized GDH integral at constant four-momentum transfer reveal a dominance of the isovector M1 transition to the $^1$S$_0$-state near threshold resulting in a negative contribution with a minimum around $Q^2\approx 0.2$ fm$^{-2}$ which is driven by the nucleon anomalous isovector magnetic moment.

description: The aim of the study was to determine the influence of selected factors on the usage efficiency of subsidies by family farms participating in support programs of the European Union. In the years 2004-2009, 70 farms from the Biłgoraj County were studied, they were divided into groups according to: the amount of subsidy, the area of arable land, their economic size, and business income. The following measures were used: employment, stocking density, intensity of organization of production, business income and family income. Farms with intensive organization of production received subsidies of up to five times more than extensive ones. Efficiency of business income increased with an increase in the selected criteria, with the highest in farms of an area over 70 ha AL and ESU over 40. Multiple linear regression confirms that the usage efficiency of EU subsidies for technical modernization depends on the farm area and its economic size and the rational application and use of farming technology in a given production process.
title: Explaining Data Patterns using Knowledge from the Web of Data
Creators: name: Tiddi, Ilaria
Publisher: name: The Open University
Year: 2016

description: Knowledge Discovery (KD) is a long-tradition field aiming at developing methodologies to detect hidden patterns and regularities in large datasets, using techniques from a wide range of domains, such as statistics, machine learning, pattern recognition or data visualisation. In most real world contexts, the interpretation and explanation of the discovered patterns is left to human experts, whose work is to use their background knowledge to analyse, refine and make the patterns understandable for the intended purpose. Explaining patterns is therefore an intensive and time-consuming process, where parts of the knowledge can remain unrevealed, especially when the experts lack some of the required background knowledge. In this thesis, we investigate the hypothesis that such interpretation process can be facilitated by introducing background knowledge from the Web of (Linked) Data. In the last decade, many areas started publishing and sharing their domain-specific knowledge in the form of structured data, with the objective of encouraging information sharing, reuse and discovery. With a constantly increasing amount of shared and connected knowledge, we thus assume that the process of explaining patterns can become easier, faster, and more automated. To demonstrate this, we developed Dedalo, a framework that automatically provides explanations to patterns of data using the background knowledge extracted from the Web of Data. We studied the elements required for a piece of information to be considered an explanation, identified the best strategies to automatically find the right piece of information in the Web of Data, and designed a process able to produce explanations to a given pattern using the background knowledge autonomously collected from the Web of Data. The final evaluation of Dedalo involved users within an empirical study based on a real-world scenario. We demonstrated that the explanation process is complex when not being familiar with the domain of usage, but also that this can be considerably simplified when using the Web of Data as a source of background knowledge.

description: Conducted research confirmed that the enterprises which incurred higher expenses on innovations gained higher labour productivity. The level of labour productivity indicator was lower in the enterprises with the lowest and average inputs on innovation than in the group, without innovative activity. The increase of labour productivity in dairy sector was first of all an effect of the change in technical equipment. Technical and organizational improvements affected the labour productivity growth less. Inconsiderable increase of labour productivity in enterprises with the lowest and average inputs on innovative activity resulted from the rationalization of employment. Expenditures on the purchase of fixed assets in this group of enterprises were very low and the technical equipment of labour increased only slightly or there was no change of this indicator
Determination of structural and functional thigh muscle properties in a healthy older population using MRI and isokinetic dynamometry
Creators: name: Vetter, Karen Pamela Ruth
Publisher: name: University of British Columbia
Year: 2010

description: Background: No consistent findings have been reported regarding the relationship between aging muscle size and strength. This may be due to the use of an inaccurate method of muscle quantification, anatomical cross-sectional area, and a limited study of muscle group and contraction type. There is little normative data on thigh muscle size and strength, or the nature of relationships among muscle groups of the thigh in a healthy older population. Purpose: 1) To determine the relationship between muscle volume (MV) of the knee flexors, knee extensors, and hip abductors, and their associated muscle strength and fatigue. 2) To investigate the reliability and validity of stereology to determine MV, and to establish the reliability of a protocol to measure hamstring muscle fatigue. 3) To investigate thigh circumference, and determine whether or not it is representative of MV and/or strength. 4) To establish normative strength ratios for this population. Subjects: Healthy older males and females, 51-80 years old. Methods: MV was calculated from MRl’s of the subject’s legs, using stereology. lsokinetic and isometric strength was measured on the Kin-Com Dynamometer, and muscle fatigue was measured using EMG during an 80% maximum voluntary contraction (MVC). Thigh circumference was determined using a Lufkin steel tape measure. Results: Average MV was 1529.57 ± 500.54 cm³ for the quadriceps, 776.46 ± 231.65 cm³ for the adductors, and 613.59 ± 159.73 cm³ for the hamstrings. All three muscle groups showed a good to excellent relationship between MV and strength (r=0.76-0.91). Thigh circumference measures at 10 cm had a strong relationship with size (r=0.55-0.72) and strength (r=0.93) of all muscle groups. Isometric strength ratios were 0.41 for hamstring : quadriceps, and 0.37 for adductor : hamstrings, where MV ratios were 0.51 and 1.03 respectively. The hamstring : quadriceps endurance time ratio was 1.74. Conclusions: The reliability of using stereology to measure MV of the thigh muscles was established, showing strong relationships between thigh muscle size and strength. Muscle strength ratios, and the evidence supporting thigh circumference measures at proximal sites on the thigh to represent functional muscle groups, will assist therapists in the treatment of healthy older adults.

description: Time-reversal symmetric charge and spin transport through a molecule comprising two-orbital channels and connected to two leads is analyzed. It is demonstrated that spin-resolved currents are generated when spin-flip processes are accompanied by a flip of the orbital channels. This surprising finding does not contradict Bardarson's theorem [J. H. Bardarson, J. Phys. A: Math. Theor. 41, 405203 (2008)] for two-terminal junctions: the transmission does possess two pairs of doubly-degenerate eigenvalues as required by the theorem. The spin-filtering effect is explicitly demonstrated for a two-terminal chiral molecular junction, modeled by a two-orbital tight-binding chain with intra-atomic spin-orbit interactions (SOI). In the context of transport through organic molecules like DNA, this effect is termed "chirality-induced spin selectivity" (CISS). The model exhibits spin-splitting without breaking time-reversal symmetry: the intra-atomic SOI induces concomitant spin and orbital flips. Examining these transitions from the point of view of the Bloch states in an infinite molecule, it is shown that they cause shifts in the Bloch wave numbers, of the size of the reciprocal single turn, whose directions depend on the left-and right-handedness of the helix. As a result, spin-up and spin-down states propagate in the opposite directions, leading to the CISS effect. To further substantiate our picture, we present an analytically-tractable expression for the 8$\times$8 scattering matrix of such a (single) molecule.

description: We have measured the thermal conductivity parallel to the a-axis of the Zn-free and 1% Zn-substituted SrCu$_{2-x}$Zn$_x$(BO$_3$)$_2$ in magnetic fields up to 14 T, in order to examine the thermal conductivity due to the multi-triplet magnons. It has been found that the thermal conductivity peak observed in the spin gap state is suppressed by the substitution of Zn for Cu in high magnetic fields above 6 T, while it is not changed in low magnetic fields below 6 T. The results suggest that the thermal conductivity peak in the spin-gap state of SrCu$_2$(BO$_3$)$_2$ is composed of not only thermal conductivity due to phonons but also that due to the multi-triplet magnons in high fields above 6 T.

description: The elaborations presents the opinion of managers concerning the possible future decision that will influence the assets-capital relations in companies. Most of managers planned to increase the value of the tangible fixed assets, that is related to their declaration that they will invest money in new fixed assets. Managers believed that increasing the equity financing in relation to value of fixed assets would be advantageous for company. The main benefit of this strategy is the fact that it would not create any additional costs in managers opinion. The entrepreneurs were in favor of increasing the level of equity capital on account of improving the financial stability of company. Manager also stated that equity financing is used effectively that why it would be beneficial for company to increase the level of own capital engagement. The managers did not see the need to change accepted policy of financing current assets. Entrepreneurs preferred long term debt financing, that builds financial stability of company. Even though managers did not plan to enlarge the foreign capital engagement.

description: A necessary precondition for secure quantum key distribution (QKD) is that sender and receiver can prove the presence of entanglement in a quantum state that is effectively distributed between them. In order to deliver this entanglement proof one can use the class of entanglement witness (EW) operators that can be constructed from the available measurements results. This class of EWs can be used to provide a necessary and sufficient condition for the existence of quantum correlations even when a quantum state cannot be completely reconstructed. The set of optimal EWs for two well-known entanglement based (EB) schemes, the 6-state and the 4-state EB protocols, has been obtained recently [M. Curty et al., Phys. Rev. Lett. 92, 217903 (2004)]. Here we complete these results, now showing specifically the analysis for the case of prepare&measure (P&M) schemes. For this, we investigate the signal states and detection methods of the 4-state and the 2-state P&M schemes. For each of these protocols we obtain a reduced set of EWs. More importantly, each set of EWs can be used to derive a necessary and sufficient condition to prove that quantum correlations are present in these protocols.

description: We present a systematic framework for noncommutative (NC) QFT within the new concept of relativistic invariance based on the notion of twisted Poincaré symmetry (with all 10 generators), as proposed in ref. [7]. This allows to formulate and investigate all fundamental issues of relativistic QFT and offers a firm frame for the classification of particles according to the representation theory of the twisted Poincaré symmetry and as a result for the NC versions of CPT and spin-statistics theorems, among others, discussed earlier in the literature. As a further application of this new concept of relativism we prove the NC analog of Haag's theorem.

description: Microalgal biomass is composed of different valuable metabolites that can satisfy the requirements of renewable biofuels, alternative proteins, carbohydrates, and food grade natural colorants. Production of a specific product from microalgae has been proved to be economically infeasible on the commercial scale except for the production of high-value products (e.g. carotenoids and phycobiliproteins). Therefore, the simultaneous extraction of multiple products is essential to bring pragmatism for the production of biofuels, proteins, and carbohydrate derived products from microalgal biomass. In order to obtain multiple products, various strategies have been implemented using potential techniques of cell disruption and biomass fractionation based on the priorities of products. Conventional approaches of downstream processing have often proved to be inefficient in the case of integrated fractionation systems. This is attributable to the divergent nature of the intracellular metabolites of microalgae and their vulnerability toward the different chemicals and conditions of those downstream processes. However, three phase partitioning (TPP), aqueous two-phase separation, membrane separation, supercritical fluid extraction (SFE), and pressurized liquid extraction (PLE) are some of the advanced techniques which have been proved to be useful in this regard. Choice of cell disruption mechanisms is critical for several purposes, such as the selective release of metabolites into a suitable solvent, preservation of bioactivity of molecules and cost-savings. Unfortunately, consolidated report for the fractionation of priority-based products from microalgal biomass using these techniques is lacking. Therefore, in this review, we have critically discussed the different strategies for the priority-based multiple products by implementation of the advanced techniques.

description: Using Comparative Price Level data for food and food products, we analysed a process of convergence in prices of these products among EU countries over the period 1999-2014. The analysis confirms the existence of beta and sigma convergence processes for overall food prices. The rate of beta convergence for overall food was 3.5%, and the half-life coefficient was 20.1 years. Beta convergence has been demonstrated for all food groups (breads and cereal products, meat, fish, milk, cheese and eggs, oils and fats, fruits, vegetables and potatoes), but rate of catch-up effect was differentiated. The severity of the convergence process sigma varied in different periods. The decrease of price differentiation occurred in 1999-2008, but formal accession in 2004 did not affected it’s pace. The sigma convergence process for food prices has not occurred after 2008, since the financial crisis.

description: We derive the full N=2 supergravity Lagrangian which contains a symplectic invariant scalar potential in terms of electric and magnetic charges. As shown in reference [1], the appearance of magnetic charges is allowed only if tensor multiplets are present and a suitable Fayet-Iliopoulos term is included in the fermion transformation laws. We generalize the procedure in the quoted reference by adding further a Fayet-Iliopoulos term which allows the introduction of electric charges in such a way that the potential and the equations of motion of the theory are symplectic invariant. The theory is further generalized to include an ordinary electric gauging and the form of the resulting scalar potential is given.

Leading order corrections to the quantum extremal surface prescription

Year: 2020
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We show that a naïve application of the quantum extremal surface (QES) prescription can lead to paradoxical results and must be corrected at leading order. The corrections arise when there is a second QES (with strictly larger generalized entropy at leading order than the minimal QES), together with a large amount of highly incompressible bulk entropy between the two surfaces. We trace the source of the corrections to a failure of the assumptions used in the replica trick derivation of the QES prescription, and show that a more careful derivation correctly computes the corrections. Using tools from one-shot quantum Shannon theory (smooth min- and max-entropies), we generalize these results to a set of refined conditions that determine whether the QES prescription holds. We find similar refinements to the conditions needed for entanglement wedge reconstruction (EWR), and show how EWR can be reinterpreted as the task of one-shot quantum state merging (using zero-bits rather than classical bits), a task gravity is able to achieve optimally efficiently.

Dynamical description of a quintom cosmological model nonminimally coupled with gravity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this work we have studied a cosmological model based on a quintom dark energy model non-minimally coupled with gravity, endowed with a specfic potential energy of the exponential squared type. For this specific type of potential energy and non-minimal coupling, the dynamical properties are analyzed and the corresponding cosmological effects are discussed. Considering the linear stability method, we have investigated the dynamical properties of the phase space structure, determining the physically acceptable solutions. The analysis showed that in this model we can have various cosmological epochs, corresponding to radiation, matter domination, and de Sitter eras. Each solution is investigated from a physical and cosmological point of view, obtaining possible constraints of the model's parameters. In principle the present cosmological setup represent a possible viable scalar tensor theory which can explain various transitional effects related to the behavior of the dark energy equation of state and the evolution of the Universe at large scales.

description: The aim of the discussion in this paper was to identify the components of the level of socio-economic development responsible for enterprises development in rural areas. In the first stage, was performed spatial autocorrelation analysis variations in the rate of enterprises and identified 4 municipalities groups: forming clusters of high values, clusters of low value, as well as cases of atypical occurrence in the high single or low values of the indicator. For each of the groups correlation analysis was conducted separately with respect to the components of the level of socio-economic development. Analysis of correlation coefficient in the designated spatial regimes revealed variable strength of a constituent of socio-economic change in the intensity of enterprises. In general for rural areas as important determinants were considered: the degree of labor market sustainability and prosperity and cohesion of the local community. The relatively high values of the correlation coefficient for all the analyzed components of the level of socio-economic development was observed only in the group of municipalities included in the clusters of high values (HH), which is adjacent communes with above-average growth enterprises.

description: We examine possible phenomenological constraints for the joint evolution of supermassive black holes (SMBH) and their host spheroids. We compare all the available observational data on the redshift evolution of the total stellar mass and star formation rate density in the Universe with the mass and accretion rate density evolution of supermassive black holes, estimated from the hard X-ray selected luminosity function of quasars and active galactic nuclei (AGN) for a given radiative efficiency, ε. We assume that the ratio of the stellar mass in spheroids to the black hole mass density evolves as (1+z)^{-α}, while the ratio of the stellar mass in disks+irregulars to that in spheroids evolves as (1+z)^{-β}, and we derive constraints on α, βand ε. We find that α>0 at the more than 4-sigma level, implying a larger black hole mass at higher redshift for a given spheroid stellar mass. The favored values for βare typically negative, suggesting that the fraction of stellar mass in spheroids decreases with increasing redshift. This is consistent with recent determinations that show that the mass density at high redshift is dominated by galaxies with irregular morphology. In agreement with earlier work, we constrain εto be between 0.04 and 0.11, depending on the exact value of the local SMBH mass density, but almost independently of αand β.

description: In studies of the environment of massive young stellar objects, recent progress in both observations and theory allows a unified treatment of data for maser and 'quasi-thermal' lines. Interferometric maser images provide information on the distribution and kinematics of masing gas on small spatial scales. Observations of multiple masing transitions provide constraints on the physical parameters. Interferometric data on 'quasi-thermal' molecular lines permits an investigation of the overall distribution and kinematics of the molecular gas in the vicinity of young stellar objects, including those which are deeply embedded. Using multiple transitions of different molecules, one can obtain good constraints on the physical and chemical parameters. Combining these data enables the construction of unified models, which take into account spatial scales differing by orders of magnitude. Here we present such a combined analysis of the environment around the ultracompact HII region in W3(OH). This includes the structure of the methanol masing region, physical structure of the near vicinity of W3(OH), detection of new masers in the large-scale shock front and embedded sources in the vicinity of the TW young stellar object.

description: The sharp increase of the prices of mineral fertilizers in 2010-2013 caused in most of farms necessity bears of higher expenses of mineral fertilizers in order to safe at least steadily level of application mineral fertilizers to plants. Most of them in this period increased costs of mineral fertilizers but part of farms that costs reduced. The aim of the study was to analyze production potential, costs of production, effectiveness and rate of investment two statistically different groups of farms specializing in field crops according to demand of mineral fertilizers, that in 2010-2013 led accountancy according to the Polish FADN. It was found that farms that in this period increased costs of mineral fertilizers are characterized by a lower the amount of labour per farm and per 1 ha utilized agriculture area (UAA), had a larger area of UAA and a better economic situation.

description: We consider discrete random fractal surfaces with negative Hurst exponent $H<0$. A random colouring of the lattice is provided by activating the sites at which the surface height is greater than a given level $h$. The set of activated sites is usually denoted as the excursion set. The connected components of this set, the level clusters, define a one-parameter ($H$) family of percolation models with long-range correlation in the site occupation. The level clusters percolate at a finite value $h=h_c$ and for $H\leq-\frac{3}{4}$ the phase transition is expected to remain in the same universality class of the pure (i.e. uncorrelated) percolation. For $-\frac{3}{4}

description: The article shows the role of social enterprises on the labour market, exemplified by social cooperatives. In market economy, basing on experiences of a number of EU states, it is possible to state that there is a reason for existence of that type of enterprises, which can be proved by their continuous development and supporting policy of the European Parliament. These enterprises are often the only chance for marginalized and socially excluded people. The work made use of provisions of the law regarding operation of social cooperatives, different types of elaborations, as well as scientific literature.
