Clinical outcomes of the Nobel Active dental implant system after one year of loading : a retrospective multicentre analysis
Creators: name: Demeter, Angela
Publisher: name: University of British Columbia
Year: 2010

description: Objective: A retrospective review of charts was conducted to assess the survival rate and marginal bone loss around Nobel Active implants after one year of loading. Methods: The study included 124 NobelActive dental implants that were placed by experienced practitioners in two private clinics and by senior Graduate Periodontics residents at the University of British Columbia. The effect of patient, medical condition, site, implant, surgeon’s experience and timing related risk factors on implant survival and marginal bone loss was evaluated. Implant failure was defined as the loss or removal of an implant. Radiographic measurements of marginal bone loss (mm) were made using Image J 1.42 software and Planmeca Romexis 2.2.7R software. Bivariate analyses were used to identify variables associated with implant failure and marginal bone loss. Risk factors that were shown to be significant (p<0.05) or thought to be relevant in previous studies were included in stepwise linear multiple regression and logistic regression analyses. Results: NobelActive implants demonstrated a survival rate of 94.4% with 7 of the 64 patients experiencing one failure. Variables considered risk factors did not have a statistically significant effect on failure. The average mean marginal bone loss of the mesial and distal measurements was 0.89+(0.95) mm during the follow up period of 12.9 months (range of 4-27 months). The bivariate analysis revealed smoking, insertion torque, anatomic location, previous bone augmentation and immediate loading as significant predictors of marginal bone loss. Significant correlations were observed between insertion torque and bone quality and insertion torque and anatomic location in terms of marginal bone loss. The multiple regression analyses identified predictors that had the largest impact on marginal bone loss, these included diabetes, smoking, anatomic location, immediate placement and immediate loading. Conclusions: The short-term clinical outcomes of survival rate and marginal bone loss for NobelActive implants are similar to those reported in literature for currently validated implant systems. Variables considered risk factors did not have a statistically significant effect on implant failure, however diabetes, smoking, anatomic location, immediate placement and immediate loading did have a significant impact on marginal bone loss.
Quantisation, Representation and Reduction; How Should We Interpret the Quantum Hamiltonian Constraints of Canonical Gravity?

description: Hamiltonian constraints feature in the canonical formulation of general relativity. Unlike typical constraints they cannot be associated with a reduction procedure leading to a non-trivial reduced phase space and this means the physical interpretation of their quantum analogues is ambiguous. In particular, can we assume that `quantisation commutes with reduction' and treat the promotion of these constraints to operators annihilating the wave function, according to a Dirac type procedure, as leading to a Hilbert space equivalent to that reached by quantisation of the problematic reduced space? If not, how should we interpret Hamiltonian constraints quantum mechanically? And on what basis do we assert that quantisation and reduction commute anyway? These questions will be refined and explored in the context of modern approaches to the quantisation of canonical general relativity.

title: Attitudes towards online and face-to-face counselling among university students in Newfoundland
Creators: name: De Paola, Lisa
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: This study investigated student attitudes towards online and face-to-face counselling at a university in Newfoundland. In addition, the variables ‘self-stigma’, ‘perceived stigma from others’ and ‘practical barriers to treatment’ were examined for their relationship with attitudes towards counselling. There were 166 students that participated in the study that included an online survey. While participants’ attitudes towards online counselling were favourable (M=39.34), students still significantly preferred face-to-face counselling (M=44.18). Students did not associate discomfort with either mode of delivery. Relationships were also found between the variables tested. Students who reported practical barriers to treatment had more negative attitudes towards face-to-face counselling (r=-0.167, p=0.038) but neither positive or negative attitudes towards online counselling. Self-stigma was negatively associated with face-to-face counselling (r=-0.526, p<0.001), but not online counselling. Perceived stigma from others was negatively associated with face-to-face counselling (r=-0.330, p<0.001), and to a lesser extent, online counselling (r=-0.0158, p<0.01). Participants in the study reported facing multiple barriers to treatment, as well as, reported medium to high levels of stigma associated with seeking mental health services. Based on the findings, it is recommended that university counselling centres find ways of increasing access to face-to-face counselling as its students’ preferred method of treatment. In addition, universities should provide outreach to decrease mental health stigma on campus. Since attitudes towards online counselling are favourable, introducing this service could be beneficial, but not with the intention that it will remove barriers to treatment. The implications of stigma and barriers to mental health treatment in these findings in light of students’ attitudes towards counselling is addressed.

description: Brain development is a combination of complex physiological changes, and various magnetic resonance imaging (MRI) techniques can help explain observed changes during development in vivo. Building upon observations from post-mortem studies, advancements in imaging and modelling techniques provide new means to further interpret the understanding of healthy brain development during childhood and adolescence. It is, however, a challenge to capture specific physiological changes, such as myelination, using MRI. This thesis uses MRI techniques – neurite orientation dispersion and density imaging (NODDI), inhomogenous magnetization transfer (ihMT), and multi-component driven equilibrium single pulse observation of T1 and T2 (mcDESPOT) – that further characterize development in white and subcortical grey matter regions in the brain by improving specificity of the MRI signal compared to conventional techniques. Measures from NODDI, ihMT, and mcDESPOT suggest an increase in myelination and/or axonal packing during development from 0-13 years.

description: A primordial vector mode and its associated magnetic field generation are investigated. Firstly, we put an observational constraint on the amount of the primordial vector mode from the seven-year WMAP data. The constraint is found as $r_v \lesssim -\frac{r}{40}+0.012$, where $r_v$ and $r$ are the amounts of vector and tensor perturbation amplitudes with respect to the scalar one, respectively. Secondly, we calculate the spectrum of magnetic fields inevitably created from the primordial vector mode, given the constraint on $r_v$. It is found that the maximum amount of magnetic fields generated from the vector mode is given by $B\lesssim 10^{-22}{\rm G} (\frac{r_v}{0.012})^{1/2} (\frac{k}{0.002})^{(n_v+1)/2}$ with $n_v$ being a spectral index of the vector mode. We find a non-trivial cancellation of the magnetic field generation in the radiation dominated era, which creates a characteristic cut off in the magnetic field spectrum around $k\approx 1.0$ Mpc$^{-1}$.

description: We introduce methods for discovering and applying sparse feature circuits. These are causally implicated subnetworks of human-interpretable features for explaining language model behaviors. Circuits identified in prior work consist of polysemantic and difficult-to-interpret units like attention heads or neurons, rendering them unsuitable for many downstream applications. In contrast, sparse feature circuits enable detailed understanding of unanticipated mechanisms. Because they are based on fine-grained units, sparse feature circuits are useful for downstream tasks: We introduce SHIFT, where we improve the generalization of a classifier by ablating features that a human judges to be task-irrelevant. Finally, we demonstrate an entirely unsupervised and scalable interpretability pipeline by discovering thousands of sparse feature circuits for automatically discovered model behaviors.

Late Paleozoic Chronostratigraphy and Tectonostratigraphy of Pericratonic Terranes near Barkerville, British Columbia: Implications for the Lower Permian (Asselian) Sugar Limestone

description: The Lower Permian Sugar limestone unit is a discontinuous calci-tubidite deposit in the Barkerville Terrane near Barkerville, British Columbia. It is here interpreted that the Pundata Thrust, which transported the Slide Mountain Terrane over the Barkerville and Cariboo terranes, separates the Sugar limestone unit from the underlying Hardscrabble Mountain succession. The Sugar limestone unit was likely deposited adjacent to an isolated carbonate platform in the Slide Mountain Ocean, prior to being thrust to its current location. This interpretation is based on the age and localized nature of the Sugar limestone unit, plus its proximity to klippen of the Slide Mountain Terrane. Regional stratigraphy and detrital zircon analysis indicate the Lower Paleozoic units of the pericratonic terranes share affinity with ancestral North America. A structural and stratigraphic reinterpretation, which incorporates ‘accordion tectonics’ was used to explain differences between the Lower and Upper Paleozoic units within the pericratonic terranes near Barkerville.
The cathedral of Milan and its fabulous donor

Publisher: name: No Publisher Supplied
Year: 2013

description: This dissertation focuses on Marco Carelli, a fourteenth-century wealthy Milanese merchant who in 1391 donated his vast patrimony to jump-start the building of the city's new cathedral. The intent in each chapter is to weave together a "life" that reflects upon its time. Through wills, merchandise inventories, confraternity statutes, accounting books, sale contracts, and trial minutes dug out of the archives of Bruges, Lille, Milan, and Venice, I reconstruct the life of a man who is in many ways typical for his period. The profile that emerges from this detailed analysis profoundly contradicts the standard historiography of the rapacious merchant who bestowed lavish gifts to buy his way into heaven by paying off time owed for his sins and as well to create earthly monuments to himself. Further, the thesis challenges the prevailing divide among scholars that separates economic and religious spheres, which leads in my judgment to an artificially bifurcated portrait of medieval society and mentality. For a medieval merchant, I argue, being a good Christian meant devoting himself to success in business and equally to charitable deeds, always making great profits on his investments. After an introductory chapter to set the scene, Chapter Two focuses on the Carelli family before Marco was someone of importance, showing how his attitudes and skills were rooted in a robust familial tradition of merchants with solid patrimony and tight networks of commercial alliances acquired through farsighted marital strategies. Then, it explores Marco Carelli's golden age and the construction of his trans-regional mercantile empire, looking at his modus operandi to understand more about choices and decisions, explaining the factors that contributed to his success, and showing the profound intertwining between business and faith, omnipresent in the merchant's life. Chapter Four examines the merchant's bequest to the Milan Cathedral through the examination of his two wills and codicil. The final chapter describes how the cathedral Fabbrica decided to celebrate his death, and to honor his body and his memory - notwithstanding that he asked for none of the pomp and ceremony, only for masses for the salvation of his soul.

description: This dissertation investigates the social practices of North American medical illustrators in the creation of images for their pharmaceutical sponsors. It tells a contemporary story of the relational attributes that support these visual science messages, using theories of social practice and research on communities of practice. Ethnographic interviews conducted with 28 medical illustrators reveal that visual accuracy is the result of a process of negotiation influenced by transitioning community interests. Medical illustrators face increased complexity in the communities of practice responsible to professional representations of science bridging research science, marketing, regulatory, legal, and health advertising interests. Medical illustrators invoke accuracy in challenging negotiations through relationships with beauty, technology and science story, in order to engage in traditional dialogues with medical science practitioners despite a commercial pharmaceutical context of dissemination. The accuracy of images is not a singular, uncomplicated entity, but a fertile area of active creation, a social construction through negotiated meaning. Medical illustrators transition to working contexts that allow them to engage in production processes that bridge dialogue and dissemination, in smaller biotech companies, not-for-profit educational contexts, or their own research science studies. This research contributes to the disparate literatures of medical illustration, practice theory, the social studies of scientific imaging and visualization, and visual culture where the material world is a complex socio-material space.

description: In view of their nature, planetary nebulae have very short lifetimes, and the chemical abundances derived so far have a natural bias favoring younger objects. In this work, we report physical parameters and abundances for a sample of old PNe located in the galactic bulge, based on low dispersion spectroscopy secured at the SOAR telescope using the Goodman Spectrograph. The new data allow us to extend our database including older, weaker objects that are at the faint end of the planetary nebula luminosity function (PNLF). The results show that the abundances of our sample are lower than those from our previous work. Additionally, the average abundances of the galactic bulge do not follow the observed trend of the radial abundance gradient in the disk. These results are in agreement with a chemical evolution model for the Galaxy recently developed by our group.

description: A road network is one of the most fundamental data of geospatial information. In order to update road maps promptly and consistently, map inference is proposed to automatically generate roads' geometric positions and topological connections from Global Positioning System (GPS) traces. Most of the existing methods are designed to deal with low-noise, densely sampled and uniformly distributed GPS traces. In this research, we propose a novel point clouds segmentation and grouping framework to infer high-quality road maps from high-noise and sparsely sampled GPS traces. First, we segment the points of GPS traces into clusters to represent nearly straight roads. Second, we group the adjacent clusters according to their spatial proximities. Finally, we generate centerlines from the clusters and refine the intersections to form road networks. Experimental results show that our methods are robust to noises and sampling rates. The generated road maps have better geometric accuracy compare to the existing methods.

description: Quantum frequency conversion (QFC), a nonlinear optical process in which the frequency of a quantum light field is altered while conserving its non-classical correlations, was first demonstrated 20 years ago. Meanwhile, it is considered an essential tool for the implementation of quantum repeaters since it allows for interfacing quantum memories with telecom-wavelength photons as quantum information carriers. Here we demonstrate efficient (>30%) QFC of visible single photons (711 nm) emitted by a quantum dot (QD) to a telecom wavelength (1,313 nm). Analysis of the first and second-order coherence before and after wavelength conversion clearly proves that important properties, such as the coherence time and photon antibunching, are fully conserved during the frequency translation process. Our findings underline the great potential of single photon sources on demand in combination with QFC as a promising technique for quantum repeater schemes.

description: Nine stratigraphic sections of Lower Moscovian (Pennsylvanian) to Sakmarian (Lower Permian) mixed carbonate-siliciclastic strata, belonging to the Canyon Fiord, Belcher Channel and Nansen formations were examined on SW Ellesmere Island, Nunavut. This succession is represented by fifteen microfacies indicative of environments ranging from open marine, reef, back-reef, shoal, lagoonal carbonates to nearshore sandstones. The studied succession is part of two long-term transgressive and regressive sequences bounded above and below by regional unconformities. These sequences are dated as Bashkirian-Kasimovian and Gzhelian-Sakmarian based on foraminiferal biostratigraphy. Superimposed on this trend are fifth-order sequences, or cyclothems, likely resulting from glacio-eustatic fluctuations. The recognition of distal and proximal cyclothems provided the basis to decipher the paleogeographic history of the area. The upper part of proximal cyclothems displays petrographic and isotopic evidence of subaerial exposure and meteoric diagenesis, which played a role in secondary porosity development, thus contributing to the economic potential of this succession.
The perception of hypertension among Haitian adults: a focused ethnography
Creators: name: Feurer, Amy E.
Publisher: name: No Publisher Supplied

description: The terms “health disparities” and “social justice” are popular buzz words in health care. These terms have been applied locally and internationally when examining the current health conditions and health resources. Since 2010, Haiti has gained much attention from the world with relief efforts and increased attention on the apparent health needs in the country. Despite these efforts, the overall health statistics of the country have not improved (Brown, 2010; Garfield & Berryman, 2012; WHO, 2014). In 2010, in response to the global epidemiological transition, the World Health Organization (WHO) shifted its attention to worldwide non-communicable diseases (NCDs) such as cardiovascular disease, cancer, diabetes, and respiratory diseases. With this shift in attention, hypertension has been identified as a worldwide health concern. The purpose of this focused ethnography is to describe Haitians’ perceptions of hypertension which contribute to the meaning of and beliefs about this chronic illness, in order to more fully understand the needs of Haitian adults with hypertension. Kleinman’s Explanatory Model of Illness (Kleinman, A., Eisenberg, L., & Good, B., (1978) serves as the theoretical background for the study. The overarching theme identified is that Haitians perceive hypertension to be a feeling that one gets which should be treated at that moment to prevent falling down. This feeling presents differently and can vary with occurrences and individuals. The feelings identified as being associated with hypertension can actually be a variety of symptoms to include: headache, blurry vision, dizziness, burning, weakness, and shortness of breath. These feelings, known as symptoms in allopathic medicine, are consistent with presenting clinical manifestations of hypertension as well as consistent with the complication of stroke often associated with uncontrolled hypertension. The findings in this study can be expanded upon to inform management and treatment options for this population as well as provide recommendations for healthcare providers serving in developing countries.

description: The present review will focus on recent development of exact-diagonali- zation (ED) methods that use Lanczos algorithm to transform large sparse matrices onto the tridiagonal form. We begin with a review of basic principles of the Lanczos method for computing ground-state static as well as dynamical properties. Next, generalization to finite-temperatures in the form of well established finite-temperature Lanczos method is described. The latter allows for the evaluation of temperatures T>0 static and dynamic quantities within various correlated models. Several extensions and modification of the latter method introduced more recently are analysed. In particular, the low-temperature Lanczos method and the microcanonical Lanczos method, especially applicable within the high-T regime. In order to overcome the problems of exponentially growing Hilbert spaces that prevent ED calculations on larger lattices, different approaches based on Lanczos diagonalization within the reduced basis have been developed. In this context, recently developed method based on ED within a limited functional space is reviewed. Finally, we briefly discuss the real-time evolution of correlated systems far from equilibrium, which can be simulated using the ED and Lanczos-based methods, as well as approaches based on the diagonalization in a reduced basis.

A functional MRI investigation into the neural correlates of the multiple-object tracking deficit in amblyopia.
Creators: name: Secen, John
Publisher: name: University of British Columbia
Year: 2010

description: Amblyopia is a visual developmental disorder defined by reduced visual acuity in one (amblyopic) eye, while the other (fellow) eye has normal visual acuity and is otherwise healthy. Deficits in motion perception – such as multiple object tracking - affect both the amblyopic eye and the fellow eye. This thesis examined the neural correlates of the multiple-object tracking deficit to further understand the cortical deficit in amblyopia. Functional data were collected as participants with and without a history of amblyopia performed the multiple-object tracking task monocularly inside a 3T MRI scanner. Participants were asked to use their attention to track 0, 1, 2 or 4 of 9 moving balls (6 deg/s) for 12 seconds. MR signal change relative to fixation, as a function of target numerosity (track 0, track 1, track 2, track 4), group (control, amblyopia), and eye were examined in six regions of interest: putative V1, MT, superior parietal lobule, frontal eye fields, anterior intraparietal sulcus, and posterior intraparietal sulcus. For all four tracking conditions, area MT was found to be less active in participants with amblyopia with both fellow and amblyopic eye viewing. When tracking 4 balls, the anterior intraparietal sulcus was found to be less active in participants with amblyopia, only with amblyopic eye viewing. This finding suggests the functional differences in this region may be subtle. Future investigations targeting the network involved in sustained attention can determine the extent to which posterior parietal function may be impaired in amblyopia. Overall, this thesis provided neuroimaging evidence that the MT region is affected in human amblyopia, and that both eyes are affected by underlying cortical changes in dorsal extra-striate areas.

description: General solutions of nonlinear ordinary differential equations (ODEs) are in general difficult to find although powerful integrability techniques exist in the literature for this purpose. It has been shown that in some scalar cases particular solutions may be found with little effort if it is possible to factorize the equation in terms of first order differential operators. In our present study we use this factorization technique to address the problem of finding solutions of a system of general two-coupled Liénard type nonlinear differential equations. We describe a generic algorithm to identify specific classes of Liénard type systems for which solutions may be found. We demonstrate this method by identifying a class of two-coupled equations for which the particular solution can be found by solving a Bernoulli equation. This class of equations include coupled generalization of the modified Emden equation. We further deduce the general solution of a class of coupled ordinary differential equations using the factorization procedure discussed in this manuscript.

description: In-situ electrochemical impedance spectroscopy was used to study the effect of lattice volume and strain on the proton conductivity of the yttrium-doped barium cerate proton conductor by applying the hydrostatic pressure up to 1.25 GPa. An increase from 0.62 eV to 0.73 eV in the activation energy of the bulk conductivity was found with increasing pressure during a unit cell volume change of 0.7%, confirming a previously suggested correlation between lattice volume and proton diffusivity in the crystal lattice. One strategy worth trying in the future development of the ceramic proton conductors could be to expand the lattice and potentially lower the activation energy under tensile strain.

description: We study a multi-field inflationary theory with separable Lagrangian, which has different speed of sound for each field. We find that the fields always coupled at perturbative level through gravitational interaction. We show that if the coupling terms among the perturbation fields are weak enough, these fields can be treated as a combination of decoupled fields, which are similar to normal modes in coupled oscillation. By virtue of such fields, the curvature perturbation at the horizon-crossing can be calculated up to the leading order of slow variation parameters via $δ\mathcal{N}$ formalism. Explicitly, we consider a model of multi-speed DBI inflation, and calculate the power spectrum in detail. The result depends on the ratio of different speeds of sound, and shows an apparent amplification when the ratio deviates from unity.

description: The Michelson Doppler Imager (MDI) aboard the Solar and Heliospheric Observatory observed the transits of Mercury on 2003 May 7 and 2006 November 8. Contact times between Mercury and the solar limb have been used since the 17th century to derive the Sun's size but this is the first time that high-quality imagery from space, above the Earth's atmosphere, has been available. Unlike other measurements this technique is largely independent of optical distortion. The true solar radius is still a matter of debate in the literature as measured differences of several tenths of an arcsecond (i.e., about 500 km) are apparent. This is due mainly to systematic errors from different instruments and observers since the claimed uncertainties for a single instrument are typically an order of magnitude smaller. From the MDI transit data we find the solar radius to be 960".12 +/- 0".09 (696,342 +/- 65 km). This value is consistent between the transits and consistent between different MDI focus settings after accounting for systematic effects.

description: Anisotropic, spatially textured electronic states often emerge when the symmetry of the underlying crystalline structure is lowered. However, the possibility recently has been raised that novel electronic quantum states with real-space texture could arise in strongly correlated systems even without changing the underlying crystalline structure. Here we report evidence for such texture in the superconducting quantum fluid that is induced by pressure in the heavy-fermion compound CeRhIn5. When long-range antiferromagnetic order coexists with unconventional superconductivity, there is a significant temperature difference between resistively- and thermodynamically-determined transitions into the superconducting state, but this difference disappears in the absence of magnetism. Anisotropic transport behaviour near the superconducting transition in the coexisting phase signals the emergence of textured superconducting planes that are nucleated preferentially along the {100} planes and that appear without a change in crystal symmetry. We show that CeRhIn5 is not unique in exhibiting a difference between resistive and bulk superconducting transition temperatures, indicating that textured superconductivity may be a general consequence of coexisting orders.

description: Diabetic patients are at higher risk of liver dysfunction compared with the normal population. Thus, using hypoglycemic agents to improve liver efficiency is important in these patients. Sodium-glucose cotransporters-2 inhibitors (SGLT2i) are newly developed antidiabetic drugs with potent glucose-lowering effects. However, recent limited evidence suggests that they have extra-glycemic benefits and may be able to exert protective effects on the liver. Hence, these drugs could serve as promising pharmacological agents with multiple benefits against different hepatic disorders. In this review, the current knowledge about the possible effects of SGLT2 inhibitors on different forms of liver complications and possible underlying mechanisms are discussed.

description: SHARC (SHAring Reward & Credit) est un groupe d'intérêt scientifique interdisciplinaire créé dans le cadre de RDA (Research Data Alliance) dans le but de faciliter le partage des données de recherche (et des ressources) par la valorisation de l'ensemble des activités pré-requises à ce partage, tout au long du cycle de vie des données. Dans ce cadre, un sous-groupe de travail SHARC élabore des grilles d'évaluation des chercheurs afin de mesurer leur niveau de prise en compte des principes FAIR dans la gestion de leurs données.

La grille d'évaluation présentée dans ce poster est destinée à être complétée par tout scientifique produisant et / ou utilisant des données. Il s'agit d'un résumé d'une grille d'évaluation plus étendue conçue pour un partage optimal des données (non encore mise en œuvre pour le moment par la plupart des scientifiques). L'évaluation est basée sur les critères de conformité FAIR. Pour remplir cet objectif, la grille affiche le minimum de critères qui doivent absolument être appliqués par les chercheurs pour attester de leur pratique FAIR. Ces critères sont organisés en 5 groupes: «Motivations de partage»; "Trouvable", "Accessible", "Interopérable" et "Réutilisable". Pour chaque critère, 4 degrés d'évaluation sont proposés ("Jamais / Non évaluable"; "Si obligatoire"; "Parfois"; "Toujours"). Au moins un degré mais un seul doit être sélectionné par critère. L'évaluation doit être effectuée pour chaque catégorie F / A / I / R; L'évaluation finale est la somme de chaque degré coché rapportée au nombre total de critères dans chaque catégorie F / A / I / R. Des règles d'interprétation prenant en compte les «motivations du partage» sont proposées.

description: The luminosity for a WASA-at-COSY experiment involving the pd reaction at 2.14 GeV proton-beam energy is determined by the forward pd elastic scattering, which yields an average beam-on-target value of [5.2\pm0.3(stat)\pm0.3(syst)]*10^{30} s^{-1}cm^{-2}. In addition, the forward pd elastic-scattering angular distribution is obtained with four-momentum transfer squared -t between 0.16 (GeV/c)^{2} and 0.78 (GeV/c)^{2} at this beam energy, which is compared with other experimental data and the pd double scattering model.

description: We show that, because of their effective electromagnetic interaction in matter, transition radiation is emitted whenever neutrinos goes across the boundary between two media with different indices of refraction. This effect occurs in the context of the standard model and does not depend on any exotic neutrino property. We examine such a phenomena and compare it with the transition radiation of a neutrino endowed with an intrinsic dipole moment.

title:  Values of Dental Hygienists in Three Different Occupational Settings
Creators: name: Koot, Adele Cereghino
Publisher: name: Old Dominion University Libraries
Year: 1978

description: This study investigated values of dental hygienists in three occupational settings: private practice, community practice, and higher education.

The Allport, Vernon, Lindzey Study of Values was used to measure values of all licensed dental hygienists in North Carolina employed in one of the three occupational settings.

An ex post facto 3x3x3x4x4 factorial research design was used. Occupational setting, age, year of graduation, educational level, and length of time in present position were the non-manipulated independent variables; and the Allport, Vernon, Lindzey Study of Values scores were used as dependent variables. Five-way analysis of variance revealed no significant value differences among the three groups, p > 0.01. Mean value scores and standard deviations of dental hygienists were also compared with scores of college females, nursing students, dental students and faculty, and female medical students. One-way analysis of variance revealed significant value differences between dental hygienists and the other four groups, E < 0.001.
Grammar of Tebul Ure (Dogon, Mali)

Subjects: Dogon, Tebul Ure, Mali, grammar

description: Reference grammar with texts. Tebul Ure (TU) is a small-population Dogon language spoken traditionally on the heights overlooking the Dogon village cluster Bamba, on the eastern cliffs of the Dogon (Bandiagara) Plateau. Its closest genetic neighbors within Dogon are Najamba-Kindige and Yanda Dom. All three are genetically part of "western" Dogon although the western/eastern genetic division does not exactly match the geography. Also included in this upload is a lexical spreadsheet in xlsx format with English and French glosses. It is based on combining the TU material in a comparative Dogon lexical spreadsheets with the TU material in comparative Dogon flora and fauna spreadsheets. Some of the material in columns toward the left may be disregarded by most end-users. Identifications and groupings of flora-fauna terminology may be useful in (re-)sorting for various purposes. These documents and additional media (audio files, images of villages) will be archived online in Deep Blue Repositories, University of Michigan Libraries, which is divided into Deep Blue Documents (e.g. pdfs) and Deep Blue Data (including media and spreadsheets). TU materials can be found by searching for "Tebul" or "Heath". Many documentary-style videos from Central Mali, especially Dogon, are also archived in Deep Blue Data.

description: There is an observational correlation between astrophysical shocks and non-thermal particle distributions extending to high energies. As a first step toward investigating the possible feedback of these particles on the shock at the microscopic level, we perform particle-in-cell (PIC) simulations of a simplified environment consisting of uniform, interpenetrating plasmas, both with and without an additional population of cosmic rays. We vary the relative density of the counterstreaming plasmas, the strength of a homogeneous parallel magnetic field, and the energy density in cosmic rays. We compare the early development of the unstable spectrum for selected configurations without cosmic rays to the growth rates predicted from linear theory, for assurance that the system is well represented by the PIC technique. Within the parameter space explored, we do not detect an unambiguous signature of any cosmic-ray-induced effects on the microscopic instabilities that govern the formation of a shock. We demonstrate that an overly coarse distribution of energetic particles can artificially alter the statistical noise that produces the perturbative seeds of instabilities, and that such effects can be mitigated by increasing the density of computational particles.

description: In any connected non-compact semi-simple Lie group without factors locally isomorphic to SL_2(R), there can be only finitely many lattices (up to isomorphism) of a given covolume. We show that there exist arbitrarily large families of pairwise non-isomorphic arithmetic lattices of the same covolume. We construct these lattices with the help of Bruhat-Tits theory, using Prasad's volume formula to control their covolumes.
