Witnessing the socially dead : testimony, violence, and Sarah
Creators: name: Van Voorthuysen, Hannah
Publisher: name: University of British Columbia
Year: 2011

description: This paper critiques the assumption, common in academic studies on survivor testimony, that trauma or pain renders the witness speechless. Through an in-depth analysis of Sarah, an extremely marginalised, socially dead, survivor-witness of multiple violences during times of war and peace in northern Uganda, I consider how such witnesses communicate in embodied ways to outline the nature of violences that they experience. Given that witnessing is a relational practice, I then explore the creative, empathetic, and imaginative ways that researchers or listeners should respond to such testimonies in order to do justice to the testimony told.

description: We present non-LTE oxygen abundances for a sample of B stars in the Orion association. The abundance calculations included non-LTE line formation and used fully blanketed non-LTE model atmospheres. The stellar parameters were the same as adopted in the previous study by Cunha & Lambert (1994). We find that the young Orion stars in this sample of 10 stars are described by a single oxygen abundance with an average value of A(O)=8.78 and a small dispersion of +/- 0.05 dex, which is of the order of the uncertainties in the analysis. This average oxygen abundance compares well with the average oxygen abundance obtained previously in Cunha & Lambert (1994): A(O) = 8.72 +/- 0.13 although this earlier study, based upon non-blanketed model atmospheres in LTE, displayed larger scatter. Small scatter of chemical abundances in Orion B stars had also been found in our previous studies for neon and argon; all based on the same effective temperature scale. The derived oxygen abundance distribution for the Orion association compares well with other results for the oxygen abundance in the solar neighborhood.

Während die Professionalisierung von Marketing eher von der Aufgabe ausgeht, die dann auf den verschiedenen Ebenen akteurs- und rollenbezogen zugeordnet und operationalisiert werden muss, geht die Professionalisierung von Dozierenden eher von den Akteuren aus, wobei die Professionalisierung der Lehrakteure dann selbst eine Mehrebenenherausforderung im Sinne der Professionalisierung des Dozierendenmanagements darstellt. Abschließend werden einige externe Professionalisierungsbedingungen in Politik, Wirtschaft und Wissenschaft für die Stärkung des Mandats wissenschaftlicher Weiterbildung – auch im Innenbereich von Hochschulen – markiert.

description: We investigate the expectations for the light Higgs signal in the MSSM in different search channels at the LHC. After taking into account dark matter and flavor constraints in the MSSM with eleven free parameters, we show that the light Higgs signal in the $gammaγ$ channel is expected to be at most at the level of the SM Higgs, while the $h\rightarrow b\bar{b}$ from W fusion and/or the $h \rightarrowτ\barτ$ can be enhanced. For the main discovery mode, we show that a strong suppression of the signal occurs in two different cases: low $M_A$ or large invisible width. A more modest suppression is associated with the effect of light supersymmetric particles. Looking for such modification of the Higgs properties and searching for supersymmetric partners and pseudoscalar Higgs offer two complementary probes of supersymmetry.

description: Patients with persistent somatoform pain disorder (PSPD) usually experience various functional impairments in pain, emotion, and cognition, which cannot be fully explained by a physiological process or a physical disorder. However, it is still not clear for the mechanism underlying the pathogenesis of PSPD. The present study aimed to explore the intra- and inter-network functional connectivity (FC) differences between PSPD patients and healthy controls (HCs). Functional magnetic resonance imaging (fMRI) was performed in 13 PSPD patients and 23 age- and gender-matched HCs. We used independent component analysis on resting-state fMRI data to calculate intra- and inter-network FCs, and we used the two-sample t-test to detect the FC differences between groups. Spearman correlation analysis was employed to evaluate the correlations between FCs and clinical assessments. As compared to HCs, PSPD patients showed decreased coactivations in the right superior temporal gyrus within the anterior default-mode network and the anterior cingulate cortex within the salience network, and increased coactivations in the bilateral supplementary motor areas within the sensorimotor network and both the left posterior cingulate cortex and the medial prefrontal cortex within the anterior default-mode network. In addition, we found that the PSPD patients showed decreased FNCs between sensorimotor network and audio network as well as visual network, between default-mode network and executive control network as well as audio network and between salience network and executive control network as well as right frontoparietal network, and increased FNCs between sensorimotor network and left frontoparietal network, salience network as well as cerebellum network, which were negatively correlated with the clinical assessments in PSPD patients. Our findings suggest that PSPD patients experience large-scale reorganization at the level of the functional networks, which suggests a possible mechanism underlying the pathogenesis of PSPD.

description: Novel electronic states resulting from entangled spin and orbital degrees of freedom are hallmarks of strongly correlated f-electron systems. A spectacular example is the so-called 'hidden-order' phase transition in the heavy-electron metal URu2Si2, which is characterized by the huge amount of entropy lost at T_{HO}=17.5K. However, no evidence of magnetic/structural phase transition has been found below T_{HO} so far. The origin of the hidden-order phase transition has been a long-standing mystery in condensed matter physics. Here, based on a first-principles theoretical approach, we examine the complete set of multipole correlations allowed in this material. The results uncover that the hidden-order parameter is a rank-5 multipole (dotriacontapole) order with 'nematic' E^- symmetry, which exhibits staggered pseudospin moments along the [110] direction. This naturally provides comprehensive explanations of all key features in the hidden-order phase including anisotropic magnetic excitations, nearly degenerate antiferromagnetic-ordered state, and spontaneous rotational-symmetry breaking.

description: Definitive screening designs (DSDs) have grown rapidly in popularity since their introduction by Jones and Nachtsheim (2011). Their appeal is that the second-order response surface (RS) model can be estimated in any subset of three factors, without having to perform a follow-up experiment. However, their usefulness as a one-step RS modeling strategy depends heavily on the sparsity of second-order effects and the dominance of first-order terms over pure quadratic terms. To address these limitations, we show how viewing a projection of the design region as spherical and augmenting the DSD with axial points in factors found to involve second-order effects remedies the deficiencies of a stand-alone DSD. We show that augmentation with a second design consisting of axial points is often the Ds-optimal augmentation, as well as minimizing the average prediction variance. Supplemented by this strategy, DSDs are highly effective initial screening designs that support estimation of the second-order RS model in three or four factors.
Quantitative modeling of responses to chronic ionizing radiation exposure using targeted and non-targeted effects

description: The biological effects of chronic ionizing radiation exposure can be difficult to study, but important to understand in order to protect the health of occupationally-exposed persons and victims of radiological accidents or malicious events. They include targeted effects (TE) caused by ionizations within/close to nuclear DNA, and non-targeted effects (NTE) caused by damage to other cell structures and/or activation of stress-signaling pathways in distant cells. Data on radiation damage in animal populations exposed over multiple generations to wide ranges of dose rates after the Chernobyl nuclear-power-plant accident are very useful for enhancing our understanding of these processes. We used a mechanistically-motivated mathematical model which includes TE and NTE to analyze a large published data set on chromosomal aberrations in pond snail (Lymnaea stagnalis) embryos collected over 16 years from water bodies contaminated by Chernobyl fallout, and from control locations. The fraction of embryo cells with aberrations increased dramatically (>10-fold) and non-linearly over a dose rate range of 0.03–420 μGy/h (0.00026–3.7 Gy/year). NTE were very important for describing the non-linearity of this radiation response: the TE-only model (without NTE) performed dramatically worse than the TE+NTE model. NTE were predicted to reach ½ of maximal intensity at 2.5 μGy/h (0.022 Gy/year) and to contribute >90% to the radiation response slope at dose rates <11 μGy/h (0.1 Gy/year). Internally-incorporated 90Sr was possibly more effective per unit dose than other radionuclides. The radiation response shape for chromosomal aberrations in snail embryos was consistent with data for a different endpoint: the fraction of young amoebocytes in adult snail haemolymph. Therefore, radiation may affect different snail life stages by similar mechanisms. The importance of NTE in our model-based analysis suggests that the search for modulators of NTE-related signaling pathways could be a promising strategy for mitigating the deleterious effects of chronic irradiation.

description: We perform Ramsey-Bordé spectroscopy on laser-cooled magnesium atoms in free fall to measure the 1S0 \rightarrow 3P1 intercombination transition frequency. The measured value of 655 659 923 839 730 (48) Hz is consistent with our former atomic beam measurement (Friebe et al 2008 Phys. Rev. A 78 033830). We improve upon the fractional accuracy of the previous measurement by more than an order of magnitude to 7e-14. The magnesium frequency standard was referenced to a fountain clock of the Physikalisch-Technische Bundesanstalt (PTB) via a phase-stabilized telecom fiber link and its stability was characterized for interrogation times up to 8000 s. The high temperature of the atomic ensemble leads to a systematic shift due to the motion of atoms across the spectroscopy beams. In our regime, this leads to a counterintuitive reduction of residual Doppler shift with increasing resolution. Our theoretical model of the atom-light interaction is in agreement with the observed effect and allows us to quantify its contribution in the uncertainty budget.

description: Introduction

Short telomere length has been suggested to be associated with atherosclerotic changes in Western populations. We examined the relationships between leukocyte telomere length and cardiovascular and renal function in a Japanese cohort.

Participants and methods

We enrolled 770 subjects who each had at least one cardiovascular risk factor. The mean age was 59.5 ± 12.2 years; mean BMI was 25.1 ± 4.6 kg/m2. We measured leukocyte telomere length (LTL) by quantitative PCR (T/S ratio), and measured other biomarkers from blood and urine samples. In addition, we assessed surrogate markers of arterial stiffness, cardiovascular organ damage and kidney function, including flow-mediated vasodilation (FMD), pulse wave velocity (PWV), carotid artery augmentation index (CAAI), and urinary albumin creatinine ratio (UACR) and eGFR.

Results

Leukocyte telomere length (T/S ratio) was inversely associated with age (r = -0.194, P<0.001), and was lower in men (1.13 ± 0.29%) than in women (1.20 ± 0.31%, P = 0.002). T/S ratio was positively associated with BMI in women (r = 0.11, P = 0.047), but not in men. LTL did not show a significant relationship to cardiovascular surrogate markers, including arterial stiffness, FMD, and PWV, but did show some relationship to CAAI, which was inversely associated with T/S ratio only in men (r = -0.159, P = 0.015). LTL did show a significant positive association with renal function measured by eGFR (r = 0.16, P<0.001) both in men and women.

Conclusions

In this Japanese sample of persons with increased cardiovascular risk, telomere length showed a relationship of longer telomere length to better renal function, but did not overall show convincing association with cardiovascular measures of arterial stiffness and target organ damage.

description: Jamming and intrusion detection are critical in 5G research, aiming to maintain reliability, prevent user experience degradation, and avoid infrastructure failure. This paper introduces an anonymous jamming detection model for 5G based on signal parameters from the protocol stacks. The system uses supervised and unsupervised learning for real-time, high-accuracy detection of jamming, including unknown types. Supervised models reach an AUC of 0.964 to 1, compared to LSTM models with an AUC of 0.923 to 1. However, the need for data annotation limits the supervised approach. To address this, an unsupervised auto-encoder-based anomaly detection is presented with an AUC of 0.987. The approach is resistant to adversarial training samples. For transparency and domain knowledge injection, a Bayesian network-based causation analysis is introduced.

description: Recent cosmological data for very large distances challenge the validity of the standard cosmological model. Motivated by the observed spatial flatness the accelerating expansion and the various anisotropies with preferred axes in the universe we examine the consequences of the simple hypothesis that the three-dimensional space has a global R^2 X S^1 topology. We take the radius of the compactification to be the observed cosmological scale beyond which the accelerated expansion starts. We derive the induced corrections to the Newton's gravitational potential and we find that for distances smaller than the S^1-radius the leading 1/r-term is corrected by convergent power series of multipole form in the polar angle making explicit the induced anisotropy by the compactified third dimension. On the other hand, for distances larger than the compactification scale the asymptotic behavior of the potential exhibits a logarithmic dependence with exponentially small corrections. The change of Newton's force from 1/r^2 to 1/r behavior implies a weakening of the deceleration for the expanding universe. Such topologies can also be created locally by standard Newtonian axially symmetric mass distributions with periodicity along the symmetry axis. In such cases we can use our results to obtain measurable modifications of Newtonian orbits for small distances and flat rotation spectra, for large distances at the galactic level.

description: We study a novel policy tool—interest rate uncertainty—that can be used to discourage inefficient capital inflows and to adjust the composition of external account between shortterm securities and foreign direct investment (FDI). We identify the trade-offs faced in navigating between external balance and price stability. The interest rate uncertainty policy discourages short-term inflows mainly through portfolio risk and precautionary saving channels. A markup channel generates net FDI inflows under imperfect exchange rate passthrough. We further investigate new channels under different assumptions about the irreversibility of FDI, the currency of export invoicing, risk aversion of outside agents, and effective lower bound in the rest of the world. Under every scenario, uncertainty policy is inflationary.

description: Nous étudions un nouvel instrument de politique, soit l’incertitude quant à la trajectoire future des taux d’intérêt, qui peut servir à décourager les entrées de capitaux inefficientes et à ajuster la répartition des investissements entre titres à court terme et investissements directs étrangers dans le compte extérieur. Nous déterminons les arbitrages à faire entre la balance extérieure et la stabilité des prix. La politique d’incertitude quant à la trajectoire future des taux d’intérêt décourage les entrées de capitaux à court terme principalement par deux canaux : les risques de portefeuille et l’épargne de précaution. Par ailleurs, un mécanisme de majoration des prix entraîne des entrées nettes d’investissements directs étrangers lorsque les variations du taux de change ne sont pas entièrement répercutées sur les prix. Nous examinons également de nouveaux mécanismes selon diverses hypothèses sur l’irréversibilité des investissements directs étrangers, la monnaie de facturation des exportations, l’aversion pour le risque des agents extérieurs et la valeur plancher des taux d’intérêt à l’étranger. Dans chaque scénario, la politique d’incertitude est inflationniste.

description: The nature of weak emission-line quasars (WLQs) is probed by comparing the Baldwin effect (BEff) in WLQs and normal quasars (QSOs). We selected 81 high-redshift (z>2.2) and 2 intermediate-redshift (z=1.66 and 1.89) WLQs. Their rest-frame equivalent widths (EWs) of the C IV emission-line and their Eddington ratio were obtained from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7) Quasar Catalogue or from Diamond-Stanic et al. We compare the parameters of WLQs with these of 81 normal quasars from Bright Quasar Survey (BQS) and 155 radio-quiet and radio-intermediate quasars detected by SDSS and Chandra. The influence of the Eddington ratio, Lbol/Ledd, and the X-ray to optical luminosity ratio,alpha_ox, on the BEff is analysed. We find that WLQs follow a different relationship on the EW(CIV)-Lbol/Ledd plane than normal quasars. This relationship disagrees with the super-Eddington hypothesis. The weakness/absence of emission-lines in WLQs does not seem to be caused by their extremely soft ionizing continuum but by low covering factor (Omega) of their broad line region (BLR). Comparing emission-line intensities indicates that the ratios of high-ionization line and low-ionization line regions (i.e. Omega_(HIL)/Omega_(LIL)) are lower in WLQs than in normal QSOs. The covering factor of the regions producing C IV and Lyalpha emission-lines are similar in both WLQs and QSOs.

description: In the name of supersymmetric double field theory, superstring effective actions can be reformulated into simple forms. They feature a pair of vielbeins corresponding to the same spacetime metric, and hence enjoy double local Lorentz symmetries. In a manifestly covariant manner --with regard to O(D,D) T-duality, diffeomorphism, B-field gauge symmetry and the pair of local Lorentz symmetries-- we incorporate R-R potentials into double field theory. We take them as a single object which is in a bi-fundamental spinorial representation of the double Lorentz groups. We identify cohomological structure relevant to the field strength. A priori, the R-R sector as well as all the fermions are O(D,D) singlet. Yet, gauge fixing the two vielbeins equal to each other modifies the O(D,D) transformation rule to call for a compensating local Lorentz rotation, such that the R-R potential may turn into an O(D,D) spinor and T-duality can flip the chirality exchanging type IIA and IIB supergravities.

description: Although sexual activity is commonly believed to be a key component of emotional well-being, little is known about the factors associated with the absence of sexual activity or its associations with self-reported happiness. Using the U.S. General Social Survey–National Death Index 2008 dataset, a series of nationally representative surveys (1988–2002), this study analyzed the sociodemographic and lifestyle factors associated with past-year sexlessness and self-reported happiness among American adults (n = 17,744). After adjustment for marital status, there were no significant time trends evident in the proportion of American adults reporting past-year sexlessness. Among participants (age = 18–89 years), 15.2% of males and 26.7% of females reported past-year sexlessness while 8.7% of males and 17.5% of females reported no sex for 5 years or more. For both genders, past-year sexlessness was most strongly associated with older age and being currently non-married in the multivariable models. Among males, the multivariable analysis also showed that sexlessness was associated with providing less than 20% of the house-hold income (OR 2.27). In female participants, sexlessness was associated with very low income, poor health, lower financial satisfaction, absence of children, and having conservative sexual attitudes (OR 1.46–3.60). For both genders, Black race was associated with a much lower likelihood of sexlessness among currently non-married adults. The purported detrimental impact of sexlessness on self-reported happiness levels was not evident in this large, nationally representative study after adjusting for sociodemographic factors. Sexless Americans reported very similar happiness levels as their sexually active counterparts.

description: We explore the sensitivity of weak gravitational lensing to second-order corrections to the spacetime metric within a cosmological adaptation of the parameterized post-Newtonian framework. Whereas one might expect nonlinearities of the gravitational field to introduce non-Gaussianity into the statistics of the lensing convergence field, we show that such corrections are actually always small within a broad class of scalar-tensor theories of gravity. We show this by first computing the weak lensing convergence within our parameterized framework to second order in the gravitational potential, and then computing the relevant post-Newtonian parameters for scalar-tensor gravity theories. In doing so we show that this potential systematic factor is generically negligible, thus clearing the way for weak lensing to provide a direct tracer of mass on cosmological scales for a wide class of gravity theories despite uncertainties in the precise nature of the departures from general relativity.

Murder in the park : civic identity-making and space in Vancouver
Creators: name: Wright, Natasha
Publisher: name: University of British Columbia

description: Stanley Park is well known in Vancouver, Canada, and globally as a site of nature in the city. Over the course of its history, this image of the park as healthy, natural, and safe has been frequently disrupted by violent and/or destructive incidents. Physical and sexual attacks, both random and calculated, have routinely occurred in the park and have resulted in frenzied media, civic, and political responses. These events unsettle Stanley Park’s identity, and as a result, multiple actors in Vancouver perform cultural work to reinvent and/or restore the Park’s meaning vis-à-vis extreme disruptions of violence. By examining the textual records of two exemplary incidents of violent disruption in the park – the 2001 queer-bashing murder of Aaron Webster and the 1992 beating and killing of six Chilean flamingos in the Park zoo – I ask: How is Stanley Park’s identity created, managed, and communicated to Vancouver residents and to visitors and tourists? How are belonging, citizenship, power, and morality implicated in this cultural work? This thesis argues that both the murder of Aaron Webster and the flamingo killings have profound implications for how we understand Stanley Park. Webster’s death and the ensuing public response demarcated rightful queer ownership of the space and at the same time provided a platform for public scrutiny and administration of queer sexuality. The flamingo murders were leveraged to bring Stanley Park ‘back’ to its ‘natural’ state, upholding a national narrative about the park as an untouched wilderness and further erasing the histories and ongoing realities of colonialism. The discourses that emerged in response to each event went well beyond the cases at hand to produce important meanings about civic identity and who belongs and does not belong in Vancouver.

description: Während für Theorielehrkräfte in der Pflegeausbildung seit 01.01.2020 ein abgeschlossenes pädagogisches Masterstudium obligat ist, erfolgt die Weiterbildung von Praxisanleitenden in den Pflegeberufen nach wie vor zumeist im außerhochschulischen Kontext im Rahmen einer berufspädagogischen Zusatzqualifikation. Für diese existieren weder verbindliche Vorgaben in Bezug auf die zu erwerbenden Kompetenzen, noch scheinen bisher vor allem pädagogische Professionalisierungsdiskurse Einzug in das Feld der Praxisanleitung erhalten zu haben. Vor dem Hintergrund der komplexen Anforderungen an Praxisanleitende aus Perspektive professionellen Pflegehandelns einerseits und pädagogischem Anleitungshandelns andererseits stellt sich die zielstellende Frage des Beitrags, inwieweit die Fort- und Weiterbildung von Praxisanleitenden ein Fall für die wissenschaftliche Weiterbildung ist.

description: We report high resolution multi-station observations of meteors by the Canadian Automated Meteor Observatory (CAMO) recorded from June 2009 to August 2010. Our survey has a limiting detection magnitude of +5 mag in R-band, equivalent to a limiting meteoroid mass of ~2*E-7 kg. The high metric trajectory accuracy (of the order of 30 m perpendicular to the solution and 200 m along-track) allows us to determine velocities with average uncertainty of < 1.5% in speed and ~0.4 degr in radiant direction. A total of 1739 meteors had measured orbits. The data has been searched for meteors in hyperbolic orbits, which are potentially of interstellar origin. We found 22 potential hyperbolic meteors among our sample, with only two of them having a speed at least three sigma above the hyperbolic limit. For our one year survey we find no clear evidence of interstellar meteoroids at mm-sizes in a weighted time-area product of ~1*E4 km^2*h. Backward integrations performed for these 22 potentially hyperbolic meteors to check for close encounters with planets show no considerable changes in their orbits. Detailed examination leads us to conclude that our few identified events are most likely the result of measurement error. We find an upper limit of f_ISP < 2*E-4/(km^2*h) for the flux of interstellar meteoroids at Earth with a limiting mass of m > 2*E-7 kg.

title: A Simple Method for Extracting the Probability of Default from American Put Option Prices
Creators: name: Chang, Bo Young

description: A put option is a financial contract that gives the holder the right to sell an asset at a specific price by (or at) a specific date. A put option can therefore provide its holder insurance against a large drop in the stock price. This makes the prices of put options an ideal source of information for a market-based measure of the probability of a firm’s default.

description: Une option de vente est un contrat financier qui donne le droit à son détenteur de vendre un actif à un prix stipulé à l’avance d’ici (ou à) une date préétablie. Les options de vente fournissent donc à leur détenteur une assurance contre une baisse importante du cours de leurs actions sous-jacentes. Ainsi, le prix des options de vente constitue une source idéale d’informations pour mesurer la probabilité de défaut d’une entreprise en fonction des données du marché.

description: Ziel dieses Beitrags ist es, die grundlegende Bedeutung der wissenschaftlichen Weiterbildung für die Professionalisierung beruflicher Handlungsfelder herauszustellen. Zu diesem Zweck wird zunächst der Professionalisierungsbegriff beleuchtet und sein Zusammenhang mit der wissenschaftlichen Weiterbildung dargestellt. Besonders in den Mittelpunkt gestellt wird im weiteren Verlauf die Bedeutung von Standards der professionellen Arbeit. Anschließend wird diskutiert, inwieweit modulare Weiterbildungsangebote besonders geeignet sind, Standardisierungsbemühungen bei der Beschreibung von Lerninhalten – als Teil der Professionalisierung sowohl der Lernenden wie auch der Lehrenden (nicht nur) in der hochschulischen Weiterbildung – erneut in den Blick zu nehmen.

title: Dynamic Competition in Negotiated Price Markets

description: "In many credit markets, prices are negotiated repeatedly. The final mortgage rate, for example, is rarely the posted price, but something that borrowers and lenders have bargained over. If borrowers are not satisfied with the rates their lenders propose, they need to search for and negotiate better offers. Borrowers often find it costly and inconvenient to switch lenders. The search and switching costs give incumbent lenders a clear advantage, allowing them to charge relatively high prices.

Repeated interactions between borrowers and lenders create the possibility of dynamic pricing: lenders compete aggressively with low prices to attract new borrowers and then raise their prices once borrowers have made a commitment.

We find such pricing patterns in the Canadian mortgage market, as most borrowers in Canada renegotiate their mortgage every five years. In this paper we develop a framework for studying this type of dynamic competition in similar negotiated-price markets. Our paper suggests that although search costs unambiguously hurt consumers, switching costs are not necessarily harmful. Consumers pay higher rates when they renew, but they reap the benefits of aggressive pricing when the loan begins."

description: "Dans bon nombre de marchés du crédit, les prix sont négociés à plusieurs reprises. Par exemple, le taux hypothécaire appliqué correspond rarement au prix affiché : il s’agit plutôt d’un taux négocié par les emprunteurs et les prêteurs. Si les emprunteurs ne sont pas satisfaits des taux proposés par les prêteurs, ils doivent chercher de meilleures offres et négocier de nouveau. Les emprunteurs trouvent souvent qu’il est coûteux et peu pratique de changer de prêteur. Les coûts de recherche et de transfert donnent aux prêteurs initiaux un net avantage qui leur permet de facturer des prix relativement élevés.

Les interactions répétées entre emprunteurs et prêteurs ouvrent la porte à un processus dynamique de fixation des prix : les prêteurs se livrent une concurrence féroce en offrant des bas prix susceptibles d’attirer de nouveaux emprunteurs, puis augmentent ces prix après que les emprunteurs ont souscrit un contrat.

Cette tendance s’observe sur le marché hypothécaire canadien, car la plupart des emprunteurs au Canada renégocient leurs prêts tous les cinq ans. Dans la présente étude, nous construisons un cadre pour examiner ce type de concurrence dynamique sur des marchés semblables où il y a négociation des prix. Les résultats obtenus laissent voir que même si les coûts de recherche sont indéniablement désavantageux pour les consommateurs, les coûts de transfert, eux, ne sont pas nécessairement néfastes. Les consommateurs paient des taux plus élevés au renouvellement de leurs prêts, mais ils tirent profit des prix très attrayants offerts au départ."

description: Dispersion effects may play a vital role, in addition to location effects, in exploring optimal addition orders of several materials in some chemical, industrial and pharmaceutical studies. Two replication-based statistical methods developed using frequentist and fiducial probability arguments are introduced in this paper to identify active dispersion effects from replicated order-of-addition experiments. Simulation results show that both approaches can maintain empirical sizes sufficiently close to the nominal level while their finite-sample performances are very similar. From a statistical perspective, the fiducial method can provide a unified probability framework to analyze dispersion effects as well as location effects. However, it is computationally more expensive than the frequentist method. Consequently, the frequentist method is recommended for real-world applications due to its low computational cost. A drug combination study is used to illustrate these two approaches. In addition, some eligible order-of-addition designs are collected in a catalogue for future work.
