Transgenic expression of human alpha-L-iduronidase in mouse and characterization of the long term pathophysiology of murine alpha-L-iduronidase deficiency
Creators: name: Russell, Christopher Spencer
Publisher: name: University of British Columbia
Year: 2009

description: Mucopolysaccharidosis type I (MPS I) is an autosomal recessive genetic disorder resulting from deficiency of alpha-L-iduronidase (IDUA), a lysosomal hydrolase required in the catabolism of heparan and dermatan sulfate glycosaminoglycans (GAGs). MPS I presents as a clinical spectrum of disease ranging from a severe multisystem disease with associated death in the first decade (Hurler syndrome) to milder forms of MPS I which are compatible with a normal lifespan (Scheie syndrome). Towards a better understanding o f MPS I, I have characterized the long term pathophysiology of murine IDUA deficiency. Skeletal manifestations represent the earliest clinical finding in MPS I mice with histologic analysis of growth plate and cortical bone revealing evidence that significant early pathology is present. Analysis of the central nervous system has revealed the novel finding of progressive neuronal degeneration within the cerebellum. In addition, brain tissue from MPS I mice show increased levels of GM₂ and GM₃ gangliosides. While persisting to adulthood and capable of mating, the IDUA deficient mouse most closely resembles severe MPS I in humans or Hurler syndrome. While many efforts are directed towards solving the problems of long term therapeutic gene expression, it remains to be determined if gene therapy will have the desired curative effects on the host of MPS I symptoms, and, additionally, whether expression of therapeutic genes in an unregulated manner will disrupt normal cellular metabolism, i.e. inducing disease. I have successfully generated murine strains which have the potential to express human IDUA in a conditional transgenic approach. In addition to genetic crosses into the IDUA deficient strain to address the benefit of IDUA expression in specific tissues at defined time points, these transgenic mice lines can provide a source of human IDUA expressing cells for use in transplantation studies. Finally, the phenotype of transgenic human IDUA expression, if any, can be determined. It is hoped that these mouse strains will be useful in determining levels, locations, and time points important to the efficacy and safety of gene therapy for MPS I.

description: Die Pacht landwirtschaftlicher Nutzflächen nimmt im Vergleich zum Kauf in Deutschland eine herausragende Stellung ein. Infolge dessen beeinflussen die Entwicklungen auf dem Pachtmarkt die strategischen Entwicklungsmöglichkeiten landwirtschaftlicher Betriebe sehr stark. Ziel des vorliegenden Beitrags ist es, Einflussfaktoren auf die Stabilität der Pachtverhältnisse aus Perspektive der Landeigner zu analysieren. Als Basis dient eine Befragung von 264 Verpächtern in Niedersachsen. Die Ergebnisse zeigen, dass eine gute Beziehung zu den Pächtern für die Befragten grundsätzlich sehr wichtig ist und diese die Wechselbereitschaft reduziert, wenngleich der Effekt von Preiszufriedenheit und tatsächlichem Pachtpreis größer ist. Es wird ferner deutlich, dass die Verpachtung an Bekannte ein wesentlicher Ansatz der Verpächter ist, um die mit der Pächtersuche verbundene Unsicherheit zu reduzieren. Dies stellt eine wichtige Eintrittsbarriere für ortsfremde Pächter dar.

description: Das Testbetriebsnetz ist eine der wichtigsten Datenquellen für einzelbetriebliche Wirtschaftsergebnisse landwirtschaftlicher Betriebe in Deutschland. Die Kennzahl ‚Nettorentabilität‘ gewinnt dabei als Vergleichsmaßstab und erfolgsbasiertes Differenzierungskriterium für unterschiedlich strukturierte Betriebe zunehmend an Bedeutung. Unterschiedliche methodische Vorgehensweisen bei der Bewertung des Faktors Boden und eine unvollständige Datenerhebung bei Personengesellschaften können jedoch zu Verzerrungen insbesondere bei der Ergebnisdarstellung führen. Je nach Auswertung oder Region weisen identisch strukturierte Betriebe erheblich voneinander abweichende Nettorentabilitäten auf. Interinstitutionelle und interregionale Vergleiche sowie die betriebswirtschaftliche Auswertung der Daten erfordern daher eine genaue Kenntnis der Berechnungsmethodik und der steuerlich bedingten Friktionen. Der Beitrag beschreibt die zu berücksichtigenden Aspekte und analysiert ihre Folgen. Möglichkeiten zur Verbesserung der Datenbasis werden aufgezeigt und ihre Umsetzbarkeit geprüft.

description: Die Beschreibung und Analyse agrarstrukturellen Wandels beschäftigt die Agrarökonomik seit langem. Anpassungsprozesse der Agrarstruktur gehen in den meisten Fällen mit Investitionen und Desinvestitionen einher. Dem Verständnis des Investitions- und Desinvestitionsverhaltens landwirtschaftlicher Unternehmerinnen und Unternehmer kommt deshalb eine besondere Bedeutung zu. In diesem Beitrag wird untersucht, inwiefern das klassische Kapitalwertkriterium und der Realoptionsansatz einen Erklärungsbeitrag für das Verhalten landwirtschaftlicher Unternehmer in Desinvestitionssituationen leisten kann. Dazu wird ein Desinvestitionsplanungsproblem definiert, für das normative Benchmarks bestimmt werden können. Die Desinvestitionszeitpunkte, die Landwirte in einem anreizkompatiblen Experiment gewählt haben, werden mit den optimalen Desinvestitionszeitpunkten verglichen, die gemäß der klassischen Investitionstheorie und gemäß dem Realoptionsansatz bestimmt wurden. Bei der Bestimmung der normativen Benchmarks wird die individuelle Risikoeinstellung der Teilnehmer berücksichtigt. Die Ergebnisse zeigen, dass der Realoptionsansatz besser als das Kapitalwertkriterium geeignet ist, um das Desinvestitionsverhalten von Landwirten zu erklären.

description: We describe perturbation theory (PT) models of galaxy bias for applications to photometric galaxy surveys. We model the galaxy-galaxy and galaxy-matter correlation functions in configuration space and validate against measurements from mock catalogs designed for the Dark Energy Survey (DES). We find that an effective PT model with five galaxy bias parameters provides a good description of the 3D correlation functions above scales of 4 Mpc/$h$ and $z < 1$. Our tests show that at the projected precision of the DES-Year 3 analysis, two of the non-linear bias parameters can be fixed to their co-evolution values, and a third (the $k^2$ term for higher derivative bias) set to zero. The agreement is typically at the 2 percent level over scales of interest, which is the statistical uncertainty of our simulation measurements. To achieve this level of agreement, our {\it fiducial} model requires using the full non-linear matter power spectrum (rather than the 1-loop PT one). We also measure the relationship between the non-linear and linear bias parameters and compare them to their expected co-evolution values. We use these tests to motivate the galaxy bias model and scale cuts for the cosmological analysis of the Dark Energy Survey; our conclusions are generally applicable to all photometric surveys.

We present a theoretical demonstration how the direction of the ensuing electron spin polarization may be determined by electrical means of two ferromagnet/semiconductor Schottky barriers.

description: Most empirical studies that declare their focus on network success or performance investigate the achievement of goals by an individual firm participating in a network. Goals that are set at the network level are mainly neglected. The aim of this study is to develop and test the model that includes goal achievement at both the firm and network levels. We test our model in the context of strategic supply chain networks in the Ukrainian food industry. The results indicate that network-level goals really exist in strategic networks and are subject to significant effect on the part of cooperation and coordination.

The method is not restricted to convolution-type kernels of the form $K(x,y)=K(x-y)$ but instead works for general kernels at competitive speeds and with exponential convergence. We provide various numerical experiments on problems with or without known analytic solutions and comparisons with other methods.

description: We propose the model of first quasars formation around the cluster of rimordial black holes (PBHs). It is supposed, that mass fraction of the universe ~10^-3 is composed of the compact clusters of PBHs, produced during the phase transitions in the early universe. The clusters of PBHs become the centers of dark matter condensation. As a result, the galaxies with massive central black holes are formed. In the process of galaxies formation the central black holes are growing due to accretion. This accretion is acompaned by the early quasar activity.

description: We study the recent claim that black NS5-branes are filled with folded strings. We calculate, in the near-extremal case, the number of folded strings at the black fivebranes interior, using different approaches, and get the exact same answer. The backreaction of the folded strings leads us to argue that the interior of the black fivebrane is AdS_2 (times a compact manifold) and that infalling matter cannot reach the interior, due to a shock wave at the horizon. These considerations also suggest a novel insight into the black fivebranes entropy.
Domino tilings of cylinders: connected components under flips and normal distribution of the twist

description: We consider domino tilings of $3$-dimensional cubiculated regions. A three-dimensional domino is a 2x2x1 rectangular cuboid. We are particularly interested in regions of the form $R_N = D \times [0,N]$ where $D$ is a fixed quadriculated disk. In dimension 3, the twist associates to each tiling $t$ an integer $Tw(t)$. We prove that, when $N$ goes to infinity, the twist follows a normal distribution. A flip is a local move: two neighboring parallel dominoes are removed and placed back in a different position. The twist is invariant under flips. A quadriculated disk $D$ is regular if, whenever two tilings $t_0$ and $t_1$ of $R_N$ satisfy $Tw(t_0) = Tw(t_1)$, $t_0$ and $t_1$ can be joined by a sequence of flips provided some extra vertical space is allowed. Many large disks are regular, including rectangles $D = [0,L] \times [0,M]$ with $LM$ even and $L,M \ge 3$. For regular disks, we describe the larger connected components under flips of the set of tilings of the region $R_N = D \times [0,N]$. As a corollary, let $p_N$ be the probability that two random tilings $T_0$ and $T_1$ of $D \times [0,N]$ can be joined by a sequence of flips conditional to their twists being equal. Then $p_N$ tends to 1 if and only if $D$ is regular. Under a suitable equivalence relation, the set of tilings has a group structure, the domino group. These results illustrate the fact that the domino group dictates many properties of the space of tilings of the cylinder $R_N = D \times [0,N]$, particularly for large $N$.

These stars are shown to be ideal targets to study this old, intriguing astrophysical problem.

The implications of the results obtained on the identification of the still unknown carrier(s) are discussed.

description: We utilize observations of 16 white dwarf stars to calculate and analyze the oxidation states of the parent bodies accreting onto the stars. Oxygen fugacity, a measure of overall oxidation state for rocks, is as important as pressure and temperature in determining the structure of a planet. We find that most of the extrasolar rocky bodies formed under oxidizing conditions, but approximately 1/4 of the polluted white dwarfs have compositions consistent with more reduced parent bodies. The difficulty in constraining the oxidation states of relatively reduced bodies is discussed and a model for the time-dependent evolution of the apparent oxygen fugacity for a hypothetical reduced body engulfed by a WD is investigated. Differences in diffusive fluxes of various elements through the WD envelope yield spurious inferred bulk elemental compositions and oxidation states of the accreting parent bodies under certain conditions. The worst case for biasing against detection of reduced bodies occurs for high effective temperatures. For moderate and low effective temperatures, evidence for relatively reduced parent bodies is preserved under most circumstances for at least several characteristic lifetimes of the debris disk.

There is an important connection between the topological properties of these complexes and lower bounds for chromatic numbers. We give a very short and conceptual proof of the fact that if G-v is a fold of G, then Bd(Hom(G,H)) collapses onto Bd Hom(G-v,H), whereas Hom(H,G) collapses onto Hom(H,G-v). We also give an easy inductive proof of the only nonelementary fact which we use for our arguments: if $ϕ$ is a closure operator on P, then $Δ(P)$ collapses onto $Δ(ϕ(P))$.

description: A modified version of a system dynamics model constructed for an EU-wide case-study project (TOP-MARD) using STELLA software was used to simulate the effects of a number of development scenarios for a remote rural area in Northern Scotland, i.e. Caithness & Sutherland, which is characterised by a high regional importance of agriculture for the local economy. In this paper, the context of the modelling work in policy and socio-economic terms is first described. This is followed by the specification of the model and of the several modelling scenarios, which relate to the reconfiguration of Pillar 2 spending within the area and an reversal of recent Structural Funds spending for 2007 onwards. The modelling results are discussed, in terms of regional population and economic trends, from 2001 to 2015. Finally, some conclusions are drawn, both about the implications of the results for such remote rural regions, and about the usefulness of this type of modelling exercise for policy analysis of rural development measures.

description: Phonon-induced spin relaxation in coupled lateral quantum dots in the presence of spin-orbit coupling is calculated. The calculation for single dots is consistent with experiment. Spin relaxation in double dots at useful interdot couplings is dominated by spin hot spots that are strongly anisotropic. Spin hot spots are ineffective for a diagonal crystallographic orientation of the dots with a transverse in-plane field. This geometry is proposed for spin-based quantum information processing.

description: We analyze the late-time relaxation dynamics for a general contagion model. In this model, nodes are either active or failed. Active nodes can fail either "spontaneously" at any time or "externally" if their neighborhoods are sufficiently damaged. Failed nodes may always recover spontaneously. At late times, the breaking of time-translation-invariance is a necessary condition for physical aging. We observe that time-translational invariance is lost for initial conditions that lie between the basins of attraction of the model's two stable stationary states. Based on corresponding mean-field predictions, we characterize the observed model behavior in terms of a phase diagram spanned by the fractions of spontaneously and externally failed nodes. For the square lattice, the phases in which the dynamics approaches one of the two stable stationary states are not linearly separable due to spatial correlation effects. Our results provide new insights into aging and relaxation phenomena that are observable in a model of social contagion processes.

This generalizes a theorem of Lackenby, removing restrictions needed about the regularity of the covers. Furthermore, we can replace the assumption that the covers have bounded Heegaard genus with the weaker hypotheses that the Heegaard splittings for the covers have Heegaard gradient zero, and also bounded width, in the sense of Scharlemann-Thompson thin position for Heegaard splittings.

description: Decoherence largely limits the physical realization of qubits and its mitigation is critical to quantum science. Here, we construct a robust qubit embedded in a decoherence-protected subspace, obtained by hybridizing an applied microwave drive with the ground-state electron spin of a silicon carbide divacancy defect. The qubit is protected from magnetic, electric, and temperature fluctuations, which account for nearly all relevant decoherence channels in the solid state. This culminates in an increase of the qubit's inhomogeneous dephasing time by over four orders of magnitude (to > 22 milliseconds), while its Hahn-echo coherence time approaches 64 milliseconds. Requiring few key platform-independent components, this result suggests that substantial coherence improvements can be achieved in a wide selection of quantum architectures.

description: Recent evidence indicates that the abundance of recurring elementary interaction patterns in complex networks, often called subgraphs or motifs, carry significant information about their function and overall organization. Yet, the underlying reasons for the variable quantity of different subgraph types, their propensity to form clusters, and their relationship with the networks' global organization remain poorly understood. Here we show that a network's large-scale topological organization and its local subgraph structure mutually define and predict each other, as confirmed by direct measurements in five well studied cellular networks. We also demonstrate the inherent existence of two distinct classes of subgraphs, and show that, in contrast to the low-density type II subgraphs, the highly abundant type I subgraphs cannot exist in isolation but must naturally aggregate into subgraph clusters. The identified topological framework may have important implications for our understanding of the origin and function of subgraphs in all complex networks.

description: Sustainability in food networks has become a dominant issue in the development of the food sector in light of the challenging scenarios one might expect in the future. Products, enterprises, chains, consumers, and regions are all affected by this discussion. Environmental, social and economic pressures require the development of strategies on how to best meet the challenges and to move the sector with its global presence and its many SMEs towards a status which is sustainable and robust enough to remain so even if future scenarios might deviate from today’s expectations (dynamic sustainability). The paper outlines a framework for research on sustainability developments, sustainability assessments, consumer communication, and the transition of enterprises and chains towards improvements in sustainability.

description: The Common Agricultural Policy is modelled as a club good providing the European Union (EU) farmer with financial benefits. We build an economic model which explains how much farmers in individual EU countries invest in rent-seeking activities in order to test for free-riding behaviour on lobbying costs. For our investigation we group the EU member countries by farm structure, and the type of benefit received. We explain the fees paid by farmers for lobbying by other countries fees, political variables, and country and regional agricultural characteristics. The model shows that some member countries free ride on others. This suggests a form of policy path dependency and leads to a suboptimal investment on lobbying of 7.5%.

description: Standard-size autonomous navigation vehicles have rapidly improved thanks to the breakthroughs of deep learning. However, scaling autonomous driving to low-power systems deployed on dynamic environments poses several challenges that prevent their adoption. To address them, we propose a closed-loop learning flow for autonomous driving mini-vehicles that includes the target environment in-the-loop. We leverage a family of compact and high-throughput tinyCNNs to control the mini-vehicle, which learn in the target environment by imitating a computer vision algorithm, i.e., the expert. Thus, the tinyCNNs, having only access to an on-board fast-rate linear camera, gain robustness to lighting conditions and improve over time. Further, we leverage GAP8, a parallel ultra-low-power RISC-V SoC, to meet the inference requirements. When running the family of CNNs, our GAP8's solution outperforms any other implementation on the STM32L4 and NXP k64f (Cortex-M4), reducing the latency by over 13x and the energy consummation by 92%.

description: Nowadays food products are increasingly produced in vertically cooperating supply chain networks. The questions of how such networks have to be designed and governed have been addressed in several well known articles. However, questions dealing with chain strategy and management are not discussed satisfyingly. In particular, the importance of network goals for the network’s strategy and management is undisclosed. Therefore, the aim of this paper is to provide the theoretical elaboration on the possible role of network goals in strategic chain management. Specifically, the following questions are inquired. First, what are the network goals? Second, how can these goals affect chain management?

description: In today’s saturated food markets with increasingly homogeneous products food quality provides an opportunity for product differentiation. We want to answer the question what determines the use of extrinsic quality cues (brands, seals of approval) in consumers’ pork purchase decision. Therefore, we accomplished a consumer survey (n=767) at different German retailers. The results show that consumers’ pork purchase at small supermarkets, use of household leaflets to make purchase decisions and modest income level determines the use of seals of approval. Consumers who buy pork at small supermarkets and discounters, and who use household leaflets use brands.
Equation of state of compressed matter: A simple statistical model
Creators: name: Site, L. Delle
Publisher: name: arXiv
Year: 2004
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We propose a simple approach for studying systems of compressed matter based on the Thomas-Fermi statistical model of single atom. The central point of our work is the development of the concept of ``statistical ionization'' by compression; in simple terms, we calculate the fraction of electrons within the atom whose positive energy, due to the compression, exceeds the negative binding energy electron-nucleus. Next we extend this concept from a single atom to macroscopic systems and write the corresponding equation of state. Positive aspects as well as limitations of the model are illustrated and discussed through all the paper.

Inclusive search for new nonresonant phenomena in multilepton final states with the CMS detector at the LHC
Creators: name: Heindl, Maximilian
Publisher: name: No Publisher Supplied
Year: 2021

description: Many theories of physics beyond the Standard Model, such as the type-III seesaw mechanism, vector-like taus, or third generation scalar leptoquarks, can be probed at the Large Hadron Collider (LHC) by searching for signatures with multiple leptons. Therefore, an inclusive search for nonresonant signatures of phenomena beyond the Standard Model in events with three or more charged leptons (electrons, muons, and hadronic taus) is performed and presented in this dissertation. The data sample corresponds to a total integrated luminosity of 138 inverse fb recorded in proton-proton collisions at 13 TeV by the CMS experiment at the LHC in 2016–2018. A signal model independent event categorization scheme is developed to probe multiple scenarios of the above-mentioned signal models. This scheme is based on the lepton charge and flavor multiplicities, invariant masses of lepton pairs, as well as on the multiplicity of b quark jets, and various kinematic variables. In the absence of any significant deviation from the background expectations, lower limits are set on the masses of type-III seesaw heavy fermions at 740 GeV for any branching fraction scenario to Standard Model leptons. Similarly, vector-like taus are excluded for masses below 920 GeV for the doublet model, and in the mass range of 120–180 GeV for the singlet model. In addition, scalar leptoquarks decaying exclusively to a top quark and a charged lepton of any flavor are excluded for masses below 1230 GeV.
Phase transition in a sexual age-structured model of learning foreign languages

description: The understanding of language competition helps us to predict extinction and survival of languages spoken by minorities. A simple agent-based model of a sexual population, based on the Penna model, is built in order to find out under which circumstances one language dominates other ones. This model considers that only young people learn foreign languages. The simulations show a first order phase transition where the ratio between the number of speakers of different languages is the order parameter and the mutation rate is the control one.

description: We study spherically symmetric gravitational collapse in cubic Horndeski theories of gravity. By varying the coupling constants and the initial amplitude of the scalar field, we determine the region in the space of couplings and amplitudes for which it is possible to construct global solutions to the Horndeski theories. Furthermore, we identify the regime of validity of effective field theory as the sub-region for which a certain weak field condition remains small at all times. We evolve the initial data using the CCZ4 formulation of the Einstein equations and horizon penetrating coordinates without assuming spherical symmetry.

description: There is a relationship between the rate of environmental taxation and the environmental consciousness of EU member states. The tax revenue collected in environmentally conscious member states is greater than that in the V-4 states (Visegrád states: Hungary, Czech Republic, Slovakia and Poland) or in the less environmentally conscious EU-15 states. Of the V-4 states, the environmental tax revenue is collected at the highest rate in the Czech Republic, which is the best situated in terms of the environment and the least amount of tax is collected in Hungary, where the environment is in the poorest state. XXXXXXXXXXXXXXXXXXXXXXX A környezeti adóbevételek százalékos aránya és a tagállamok környezeti tu-datossága között kapcsolat van, a környezetileg tudatosabb tagállamokban jel-lemzően nagyobb arányú a környezeti adóbevétel, mint a V4 államokban vagy a környezetileg kevésbé tudatos tagállamokban. A környezeti adókból származó adóbevétel arányát három féle viszonyítási alap szerint vizsgálva nagymértékű egyezőség figyelhető meg az országok sorrendjében. A V4 államok közül környe-zeti szempontból legkedvezőbb helyzetben lévő Csehországban a legmagasabb, legkedvezőtlenebb helyzetben levő Magyarországon legalacsonyabb a környezeti adóbevétel aránya. A magyar adórendszerben a környezeti adók aránya kicsi, je-lentősen elmarad az EU 15 és a V4 államokban megfigyelhető értékektől is.
Prebiotic precursors of the primordial RNA world in space: Detection of NH$_{2}$OH

description: One of the proposed scenarios for the origin of life is the primordial RNA world, which considers that RNA molecules were likely responsible for the storage of genetic information and the catalysis of biochemical reactions in primitive cells, before the advent of proteins and DNA. In the last decade, experiments in the field of prebiotic chemistry have shown that RNA nucleotides can be synthesized from relatively simple molecular precursors, most of which have been found in space. An important exception is hydroxylamine, NH$_2$OH, which, despite several observational attempts, it has not been detected in space yet. Here we present the first detection of NH$_2$OH in the interstellar medium towards the quiescent molecular cloud G+0.693-0.027 located in the Galactic Center. We have targeted the three groups of transitions from the $J$=2$-$1, 3$-$2, and 4$-$3 rotational lines, detecting 5 transitions that are unblended or only slightly blended. The derived molecular abundance of NH$_2$OH is (2.1$\pm$0.9)$\times$10$^{-10}$. From the comparison of the derived abundance of NH$_2$OH and chemically related species, with those predicted by chemical models and measured in laboratory experiments, we favor the formation of NH$_2$OH in the interstellar medium via hydrogenation of NO on dust grain surfaces, with possibly a contribution of ice mantle NH$_3$ oxidation processes. Further laboratory studies and quantum chemical calculations are needed to completely rule out the formation of NH$_2$OH in the gas phase.

Identifying child abuse : a structural equation modeling analysis of history of abuse and westernization on perceptions of abuse among Asian-descent and European-descent students
Creators: name: Kennedy, Margaret Alexis
Publisher: name: University of British Columbia
Year: 2009

description: Structural equation modeling (SEM) analyses were used to explore the relationships among Westernization, histories of child abuse and perceptions of child abuse. Students (n=601) from a large Canadian university completed a research questionnaire about personal histories of child abuse and were asked to provide information on what they would consider to be physically abusive or emotionally abusive behaviour. Perceptions of abuse were measured in part through participants' responses after viewing a video with a staged incident of physical abuse and a scenario depicting emotional abuse. The participants were culturally diverse and were assessed both on their ethnicity and their levels of acculturation. A three-factor model was specified for 225 participants. In addition, the model was re-specified and compared across two samples, a Chinese-descent sample (n=200) and a European-descent sample (n=176). The data suggested that perceptions of abusive behaviour were related to personal experiences with child abuse. This relationship held true for both physical and emotional abuse. Histories of abuse were measured by the Parent-Child Conflict Tactics Scale, the Child Abuse and Trauma Scale and the Parent Discipline Attitudes Survey. Westernization, as measured by generation level, the Vancouver Index of Acculturation and the Filial Piety scale, however, did not predict perceptions of abusive behaviour. Contrary to research findings in Asia, filial piety was not significantly correlated with acceptance of physical discipline. The model for physical abuse and the model for emotional abuse were equivalent for the two samples according to multi-group structural equation model constraints. Participants appeared to assess abuse equivalently intra-culturally and cross-culturally. The age of the child being disciplined changed the acceptability of the physical and emotional discipline strategies. Implications for abuse prevention education are discussed.
