description: Coherent grazing-incidence small-angle X-ray scattering is used to investigate the average kinetics and the fluctuation dynamics during self-organized nanopatterning of silicon by Ar$^+$ bombardment at 65$^{\circ}$ polar angle. At early times, the surface behavior can be understood within the framework of linear theory. The transition away from the linear theory behavior is observed in the dynamics through the intensity correlation function. It quickly evolves to exhibit stretched exponential decay on short length scales and compressed exponential decay on length scales corresponding the dominant structural length scale - the ripple wavelength. The correlation times also peak strongly at the ripple length scale. This behavior has notable similarities but also significant differences with the phenomenon of de Gennes narrowing. Overall, this dynamics behavior is found to be consistent with simulations of a nonlinear growth model.

description: We present the results of narrow-band and broad-band imaging with the Very Large Telescope of the field surrounding the radio galaxy TN J0924-2201 at z = 5.2. Fourteen candidate Ly alpha emitters with a rest-frame equivalent width of > 20 A were detected. Spectroscopy of 8 of these objects showed that 6 have redshifts similar to that of the radio galaxy. The density of emitters at the redshift of the radio galaxy is estimated to be a factor 1.5-6.2 higher than in the field, and comparable to the density of Ly alpha emitters in radio galaxy protoclusters at z = 4.1, 3.1 and 2.2. The Ly alpha emitters near TN J0924-2201 could therefore be part of a structure that will evolve into a massive cluster. These observations confirm that substantial clustering of Ly alpha emitters occurs at z > 5 and support the idea that radio galaxies pinpoint high density regions in the early Universe.

description: We present a grand canonical Monte Carlo simulation study of the phase diagram of a Lennard-Jones fluid adsorbed in a fractal and highly porous aerogel. The gel environment is generated from an off-lattice diffusion limited cluster-cluster aggregation process. Simulations have been performed with the multicanonical ensemble sampling technique. The biased sampling function has been obtained by histogram reweighting calculations. Comparing the confined and the bulk system liquid-vapor coexistence curves we observe a decrease of both the critical temperature and density in qualitative agreement with experiments and other Monte Carlo studies on Lennard-Jones fluids confined in random matrices of spheres. At variance with these numerical studies we do not observe upon confinement a peak on the liquid side of the coexistence curve associated with a liquid-liquid phase coexistence. In our case only a shouldering of the coexistence curve appears upon confinement. This shoulder can be associated with high density fluctuations in the liquid phase. The coexisting vapor and liquid phases in our system show a high degree of spatial disorder and inhomogeneity.

The child welfare response to domestic violence : exploring the concurrence between the literature, best practice guidelines and worker perception in the Ministry for Children and Family Development
Creators: name: DeGeer, Ian G.
Publisher: name: University of British Columbia
Year: 2009

description: Increasingly; child welfare authorities have become involved with families where domestic violence is an issue. This has been the result of improved understanding of the impact of witnessing domestic violence on children. However, child welfare has been criticized for the oppressive nature of the interventions with families where domestic violence has occurred. Critics have argued that an absence of understanding about domestic violence by social workers in child welfare has resulted in oppressive practice towards women and children. This study explored the perceptions of social workers in British Columbia's Ministry for Children and Family Development - South Fraser Region about the barriers to best practice in cases of domestic violence. An extensive literature review revealed eight barriers to best practice that contradict current best practice guidelines for cases of domestic violence. The findings of this study revealed that social workers identified that similar barriers to best practice exist in the South Fraser Region, thereby confirming the concerns in the literature. The use of factor analysis revealed that social workers are attempting to work with non-offending parents in amore supportive manner, but there continue to be systemic problems associated with child welfare services that impede workers ability to practice in a non-oppressive manner. Recommendations for improvement of service provision are outlined and discussed.

description: Sample selection is a necessary preparation for weak lensing measurement. It is well-known that selection itself may introduce bias in the measured shear signal. Using image simulation and the Fourier_Quad shear measurement pipeline, we quantify the selection bias in various commonly used selection function (signal-to-noise-ratio, magnitude, etc.). We proposed a new selection function defined in the power spectrum of the galaxy image. This new selection function has low selection bias, and it is particularly convenient for shear measurement pipelines based on Fourier transformation.

description: In the continuation of a preceding work, we derive a new expression for the metric in the near zone of an isolated matter system in post-Newtonian approximations of general relativity. The post-Newtonian metric, a solution of the field equations in harmonic coordinates, is formally valid up to any order, and is cast in the form of a particular solution of the wave equation, plus a specific homogeneous solution which ensures the asymptotic matching to the multipolar expansion of the gravitational field in the exterior of the system. The new form provides some insights on the structure of the post-Newtonian expansion in general relativity and the gravitational radiation reaction terms therein.

A vizsgálatba vont állomány (több mint 6 ezer koca és éves átlagban 100 ezer hízósertés) adatai alapján folyamatosan növekvő termelési költségek mellett számottevő különbség mutatkozott az integráción kívüli, illetve az iparszerű termelési rendszerhez (integrációhoz) tartozó gazdaságok eredményei között. A kocák reprodukciós teljesítménye és a takarmány értékesülés fajlagos mutatói közötti különbségek jelentősen differenciálták a két csoporthoz tartozó gazdaságok jövedelmét, az iparszerű rendszerhez tartozók javára. -------------------------------------------------------- Nationwide data indicate that the pork industry is in crisis. Our survey of 11 farms in the Transdanubian region, done between 2006 and 2008, shows that reasonable revenues can be achieved by quality operations which are appropriately organised. The data of the animal stock covered by the research (over 6,000 sows and an average of 100,000 store-pigs a year) indicated that while production costs were continuously increasing, there was a significant difference between farms depending on whether they were part of the industrialised production system (integration). The specific indices measuring the reproductive performance of sows and the utilisation of feedstuff clearly showed the division between the two groups, and their revenues, revealing that farms belonging to the industrialised production system fared better in this regard.
Heat-Kernel Approach to UV/IR Mixing on Isospectral Deformation Manifolds

description: We work out the general features of perturbative field theory on noncommutative manifolds defined by isospectral deformation. These (in general curved) `quantum spaces', generalizing Moyal planes and noncommutative tori, are constructed using Rieffel's theory of deformation quantization for action of $\R^l$. Our framework, incorporating background field methods and tools of QFT in curved spaces, allows to deal both with compact and non-compact spaces, as well as with periodic or not deformations, essentially in the same way. We compute the quantum effective action up to one loop for a scalar theory, showing the different UV/IR mixing phenomena for different kinds of isospectral deformations. The presence and behavior of the non-planar parts of the Green functions is understood simply in terms of off-diagonal heat kernel contributions. For periodic deformations, a Diophantine condition on the noncommutativity parameters is found to play a role in the analytical nature of the non-planar part of the one-loop reduced effective action. Existence of fixed points for the action may give rise to a new kind of UV/IR mixing.

description: The current obesity crisis in the United States is generating numerous alternative policy options for combating the problem. One alternative that has been widely proposed is an excise or sales tax on sugar-sweetened non-alcoholic beverages. This literature started out within a very simple partial equilibrium framework. Not considering the feedback effects (or general equilibrium effects) across interrelated market is a shortcoming of these partial equilibrium analyses. Our study is carried out to ascertain stochastic partial and general equilibrium calorie, body weight and revenue effects of a tax on sugar-sweetened beverages as well as incidence of such tax. We used Nielsen Homescan data on prices and quantities of selected non-alcoholic beverages purchased over the period January 1998 through December 2008. Probability density functions (pdfs) generated using simulations of calorie outcomes reveal that the calorie reduction due to tax on sugar-sweetened beverages is between 465 and 716 calories per person per month. However, consideration of both direct and indirect effects in generating the effect of the tax on sugar-sweetened beverages reveal reduction as low as 199 calories per person per month and as high as707 calories per person per month.

description: As they evolve, white dwarfs undergo major changes in surface composition, a phenomenon known as spectral evolution. In particular, some stars enter the cooling sequence with helium atmospheres (type DO) but eventually develop hydrogen atmospheres (type DA), most likely through the upward diffusion of residual hydrogen. Our empirical knowledge of this process remains scarce: the fractions of white dwarfs that are born helium-rich and that experience the DO-to-DA transformation are poorly constrained. We tackle this issue by performing a detailed model-atmosphere investigation of 1806 hot ($T_{\rm eff} \ge 30,000$ K) white dwarfs observed spectroscopically by the Sloan Digital Sky Survey. We first introduce our new generations of model atmospheres and theoretical cooling tracks, both appropriate for hot white dwarfs. We then present our spectroscopic analysis, from which we determine the atmospheric and stellar parameters of our sample objects. We find that $\sim$24% of white dwarfs begin their degenerate life as DO stars, among which $\sim$2/3 later become DA stars. We also infer that the DO-to-DA transition occurs at substantially different temperatures ($75,000 \ {\rm K} > T_{\rm eff} > 30,000$ K) for different objects, implying a broad range of hydrogen content within the DO population. Furthermore, we identify 127 hybrid white dwarfs, including 31 showing evidence of chemical stratification, and we discuss how these stars fit in our understanding of the spectral evolution. Finally, we uncover significant problems in the spectroscopic mass scale of very hot ($T_{\rm eff} > 60,000$ K) white dwarfs.

description: We demonstrate a new simple technique to measure IR frequencies near 30 THz using a femtosecond (fs) laser optical comb and sum-frequency generation. The optical frequency is directly compared to the distance between two modes of the fs laser, and the resulting beat note is used to control this distance which depends only on the repetition rate fr of the fs laser. The absolute frequency of a CO2 laser stabilized onto an SF6 two-photon line has been measured for the first time. This line is an attractive alternative to the usual saturated absorption OsO4 resonances used for the stabilization of CO2 lasers. First results demonstrate a fractional Allan deviation of 3.10-14 at 1 s.

description: Despite extensive study, fundamental understanding of self-organized patterning by broad-beam ion bombardment is still incomplete and controversial. Understanding the nanopatterning of elemental semiconductors, particularly silicon, is both foundational for the broader field and of intrinsic scientific and technological interest itself. This is the second component of a two-part investigation of the kinetics and fluctuation dynamics of self-organized nanoscale ripple development on silicon during 1 keV Ar$^+$ (Part I) and Kr$^+$ bombardment. Here, it's found that the ion-enhanced viscous flow relaxation is essentially equal for Kr$^+$-induced patterning as previously found for Ar$^+$ patterning. The magnitude of the surface curvature dependent roughening rate in the early stage kinetics is larger for Kr$^+$ than for Ar$^+$, qualitatively consistent with expectations for erosive and mass redistributive contributions to the initial surface instability. As with the Ar$^+$ case, fluctuation dynamics in the late stage show a peak in correlation time at the length scale corresponding to the dominant structural feature on the surface -- the ripples. Analogy is made to the phenomenon of de Gennes narrowing in liquids, but significant differences are also pointed out. Finally, it's shown that speckle motion during the surface evolution can be analyzed to determine spatial inhomogeneities in erosion rate and ripple velocity on the surface. This allows the direction and speed of ripple motion to be measured in real time, a unique capability for measuring these fundamental parameters outside the specialized environment of FIB/SEM systems.

Neural mechanisms of Levodopa induced motor complications in Parkinson’s disease
Creators: name: Bowden, Gregory Neil
Publisher: name: University of British Columbia
Year: 2009

description: Parkinson's disease (PD) is a common neurodegenerative disorder characterized by a loss of dopamine (DA) neurons. Motor fluctuations and dyskinesia are common complications that appear with long-term Levodopa (Ldopa) therapy. A rat model of unilateral Parkinsonism was formed using 6-OHDA and treatment with L-dopa was conducted to induce dyskinesia. The abnormal involuntary movement (AIM) rating scale was used for monitoring the time-action curve of the L-dopa response. Striatal DA levels were investigated using in vivo microdialysis. Post-mortem brain sections were taken for autoradiography and in situ hybridization histochemistry. The validation study (Chapter II) indicates that the AIM rating scale is reproducible across test days and within its four subscores. This offers a reliability that allows for an expanded analysis of the time action curve of dyskinetic movements. The chronic L-dopa treatment study (Chapter III) demonstrates that AIM magnitude (Emax) correlates negatively with latency to onset and decay time, but positively with rising time. We found that prodynorphin mRNA in the striatum has a significant negative correlation with decay time, and a positive correlation with Emax. This upregulation of prodynorphin mRNA, is also associated with L-dopainduced dyskinesia and may contribute to the development of motor fluctuations. The microdialysis experiments (Chapter IV) show that a DA surge response is necessary to cause L-dopa-induced AIM. The time concentration curve of extracellular DA shows a left shift in dyskinetic rats after chronic pulsatile treatment. Also, partially lesioned rats show a smaller increase in extracellular DA levels with greater increase in extracellular DOPAC levels after L-dopa injection, compared to those with severe striatal DA terminal loss. This suggests that the severity of DA terminal loss is a factor determining the level of "DA surge" in the striatum after L-dopa administration. Experimental observations from this project indicate that both severe DA terminal loss in the striatum and L-dopa treatment contribute to the development of "DA surge" in the striatum with a therapeutic dose of L-dopa, which is in turn responsible for the development of response fluctuations and dyskinesia in a rat model of Parkinson's disease.

description: This article quantifies the effect of the 2006 food-borne illness spinach outbreak on harvested acreage for the fresh spinach market. In September 2006, fresh spinach contaminated with E. coli O157:H7 caused hundreds of consumer illnesses across the U.S. and a few deaths. The outbreak was detrimental to the spinach industry causing a significant decrease in the demand for spinach. Spinach growers were prohibited from harvesting spinach until more was known about the contamination. According to the Census of Agriculture, harvested spinach acreage for the fresh market fell by 17% from before the outbreak. Due to the unanticipated effects resulting from the outbreak, farms potentially decreased their acreage of fresh market spinach to reduce profit uncertainty caused by the probability of a future outbreak. Alternatively, farms may have increased the acreage of a less risky commodity in order to provide a method to remove potential contamination.

description: We study the supersymmetric embeddings of different D-brane probes in the AdS_5 x T^{1,1} geometry. The main tool employed is kappa symmetry and the cases studied include D3-, D5- and D7-branes. We find a family of three-cycles of the T^{1,1} space over which a D3-brane can be wrapped supersymmetrically and we determine the field content of the corresponding gauge theory duals. Supersymmetric configurations of D5-branes wrapping a two-cycle and of spacetime filling D7-branes are also found. The configurations in which the entire T^{1,1} space is wrapped by a D5-brane (baryon vertex) and a D7-brane are also studied. Some other embeddings which break supersymmetry but are nevertheless stable are also determined.

description: A stated preference experiment is conducted to elicit consumer WTPs for various blueberry attributes. The mixed logit model is employed to account for consumer heterogeneity. The model is set up in the WTP space where the distributions of WTPs are directly specified. Considering the high diversity of consumer perception and the remarkable benefits from differential marketing, we apply the hierarchical Bayesian approach and the discussion is based on the individual level WTP estimates. The results show that “local produced” attribute is preferred over simply “produced in the U.S.” by most respondents. By contrast, less than 50% of the respondents are willing to pay premium for organic blueberries. In addition, hardly any relationship between demographics and WTPs is detected. Demographic information seems to have little explanation power for consumer perception in small purchases like fruits or vegetables. In this light, the hierarchical Bayesian approach is critical to the practice of differential marketing strategies.

description: Η έννοιας της μνήμης είναι ένα πολυδιάστατο πέπλο ερμηνειών, το οποίο εξερευνώντας το, ανακαλύπτεται ένα αχανές πεδίο εφαρμογής. Η προκειμένη έρευνα, όμως, επικεντρώνεται στον τρόπο με τον οποίο η μνήμη συνδέεται με την αστική αφήγηση, στοχεύοντας κυρίως στη διερεύνηση των τρόπων με τους οποίους εργαλειοποιήθηκε αυτή στην σύγχρονη εποχή μέσα από το έργο δύο μεγάλων αρχιτεκτόνων του 20ου αιώνα. Για τον λόγο αυτό, παρουσιάζεται η αναδρομή και ορίζεται η πορεία της απεικόνισης του αστικού χώρου σε δύο διακριτές χρονικές περιόδους. Η διαδικασία ανάγνωσης και απεικόνισης των αστικών στοιχείων, που κατά τον εκάστοτε εξεταζόμενο αρχιτέκτονα είναι ικανή να αποδώσει την ταυτότητα της πόλης, διαχωρίζεται ως εξής: Στα σημαίνοντα συστήματα του 16ου αιώνα, στα οποία η πόλη ορίζεται μέσα από τη μνήμη και τα μνημεία της, και στο σύγχρονο αρχιπέλαγος του δεύτερου μισού του 20ου αιώνα, στο οποίο η πόλη είναι το μέσο που θέτει και ορίζει το τι εστί μνήμη στον αστικό χώρο.
description: The starting point of this research is a word, a concept with many manifestations:
 "Memory"
The concept of memory is a multidimensional veil of definitions, which, when explored, reveals a vast field of application. This research, however, focuses on the way in which memory is linked to the urban narrative, aiming primarily to explore the ways in on how it has been used in the modern era through the work of two great twentieth-century architects. To this end, a retrospective is presented and the trajectory of the representation of urban space in two distinct time periods is defined. The process of reading and depicting urban elements, which, according to the architect in question, is capable of conveying the identity of the city, is divided as follows: In the signifying systems of the 16th century, in which the city is defined through its memory and monuments, and in the contemporary archipelago city of the second half of the 20th century, in which the city is the medium that poses and defines what memory is in urban space.
However, in the process of researching and interpreting this purpose, some concerns and questions arose which are worth exploring to enable an in-depth examination of the main topic of this research. How is memory defined and functions and what is its relationship with space-time? What is the role of memory in the human perceptual ability to understand urban space and why is it considered important in this reading process? Can architecture and built space function as a means of expressing and narrating the city through monuments? And finally, how do all of the above questions relate to the representation of urban space?
A Role for CpG methylation mediated epigenetic transcriptional silencing during olfactory neuronal development

description: Epigenetic control of chromatin structure plays a critical role in regulated transcriptional silencing in eukaryotes (Li 2002). It is associated with the inaccessibility of DNA to transcription promoting factors and is critical for gene regulation during development. DNA methylation is a mechanism of epigenetic control and leads to the silencing of genes directly by blocking transcription factors from binding to promoters and indirectly by recruiting chromatin remodelling complexes leading to chromatin condensation and exclusion of transcription factors from their binding sites. We have identified Dnmt3b as a gene that is upregulated following bulbectomy induced neurogenesis in the mouse. DNMT3b is a de novo methyltransferase which can methylate previously unmethylated genomic DNA. New patterns of methylation give rise to new patterns of stable and heritable transcriptional silencing. De novo methylation and the establishment of new methylation patterns may play a role in cell lineage refinement and cellular differentiation, silencing genes that are no longer needed in a cell lineage. Here we have examined if DNA methylation may be a potential regulator of olfactory receptor neuron development. In silico analysis of OR gene clusters showed that functional OR genes are not associated with CpG motifs of characteristically high or characteristically low methylation density suggesting that dynamic control of CpGs is a potential controller of OR gene expression during ORN development. In vivo analysis showed that both DNMT3b and the other known de novo DNA methyltransferase, DNMT3a are expressed in the olfactory epithelium from E11 to adulthood and that they are differentially and sequentially expressed by ORNs at different stages of maturation during development. We have previously generated an in vitro model of ORN development to help us understand ORN developmental events. Analyses of DNMT3b expression in the OP27 olfactory receptor cell line show that DNMT3b is not recruited to DNA replication forks. DNMT3b is thus not likely to be involved in maintenance methylation and may therefore be involved in mediating changes in transcriptional competence during ORN differentiation.

description: The objective of this study is to measure trade costs incurred by major U.S. regions when trading manufactured food products with other countries. Trade costs in this study’s context refer to all factors limiting exchange of goods and services among countries, e.g. policy, geographic and institutional barriers. Such costs are often measured as frictions in a micro-founded gravity model as in Anderson and van Wincoop (2004) and Jacks et al. (2011). In this study, the gravity framework is extended to identify regional trade costs in the U.S. food manufacturing industry. The new measures of trade costs not only capture the variation over time in trade fictions among countries, but also allow for further examination of their underlying sources: policy, geographic and institutional factors.
description: This study allows for variation of trade costs among regions, since a single trade costs measure may not appreciate the large number and diverse regions of the United States through which trade in food manufacturing occurs.

description: Cocoa beans are produced in equatorial and sub-equatorial regions of West Africa, Southeast Asia and South America. These are also the regions most affected by El Nino Southern Oscillation (ENSO) -- a climatic anomaly affecting temperature and precipitation in many parts of the world. Thus, ENSO, has a potential of affecting cocoa production and, subsequently, prices on the world market. This study investigates the benefits of using a measure of ENSO variable in world cocoa price forecasting through the application of a smooth transition autoregression (STAR) modeling framework to monthly data to examine potentially nonlinear dynamics of ENSO and cocoa prices. The results indicate that the nonlinear models appear to outperform linear models in terms of out-of-sample forecasting accuracy. Furthermore, the results of this study indicate evidence of Granger causality between ENSO and cocoa prices.

description: We provide a general framework which allows one to obtain the dynamics of $N$ noninteracting spatially indistinguishable particles locally coupled to separated environments. The approach is universal, being valid for both bosons and fermions and for any type of system-environment interaction. It is then applied to study the dynamics of two identical qubits under paradigmatic Markovian noises, such as phase damping, depolarizing and amplitude damping. We find that spatial indistinguishability of identical qubits is a controllable intrinsic property of the system which protects quantum entanglement against detrimental noise.

description: Fact checking is an essential challenge when combating fake news. Identifying documents that agree or disagree with a particular statement (claim) is a core task in this process. In this context, stance detection aims at identifying the position (stance) of a document towards a claim. Most approaches address this task through a 4-class classification model where the class distribution is highly imbalanced. Therefore, they are particularly ineffective in detecting the minority classes (for instance, 'disagree'), even though such instances are crucial for tasks such as fact-checking by providing evidence for detecting false claims. In this paper, we exploit the hierarchical nature of stance classes, which allows us to propose a modular pipeline of cascading binary classifiers, enabling performance tuning on a per step and class basis. We implement our approach through a combination of neural and traditional classification models that highlight the misclassification costs of minority classes. Evaluation results demonstrate state-of-the-art performance of our approach and its ability to significantly improve the classification performance of the important 'disagree' class.

description: It is not common to consider the role of uncertainties in the rate coefficients used in interstellar gas-phase chemical models. In this paper, we report a new method to determine both the uncertainties in calculated molecular abundances and their sensitivities to underlying uncertainties in the kinetic data utilized. The method is used in hot core models to determine if previous analyses of the age and the applicable cosmic-ray ionization rate are valid. We conclude that for young hot cores ($\le 10^4$ yr), the modeling uncertainties related to rate coefficients are reasonable so that comparisons with observations make sense. On the contrary, the modeling of older hot cores is characterized by strong uncertainties for some of the important species. In both cases, it is crucial to take into account these uncertainties to draw conclusions from the comparison of observations with chemical models.

description: The intrinsic antiferromagnetic (AFM) interlayer coupling in two-dimensional magnetic topological insulator MnBi$_2$Te$_4$ places a restriction on realizing stable quantum anomalous Hall effect (QAHE) [Y. Deng et al., Science 367, 895 (2020)]. Through density functional theory calculations, we demonstrate the possibility of tuning the AFM coupling to the ferromagnetic coupling in MnBi$_2$Te$_4$ films by alloying about 50% V with Mn. As a result, QAHE can be achieved without alternation with the even or odd septuple layers. This provides a practical strategy to get robust QAHE in ultrathin MnBi$_2$Te$_4$ films, rendering them attractive for technological innovations.
