Quantifying the use of the statin antilipemic drugs: Comparisons and contrasts between Nova Scotia, Canada, and Queensland, Australia

Background: jurisdictions are developing public drug insurance systems to improve access to pharmaceuticals, cost-effective prescribing, and patient health and well-being. We compared 2 Jurisdictions with different pharmaceutical policies to determine prescribing patterns for 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (le, statins). Objective: The aim of this work was to investigate the feasibility of using available prescription admimstrative databases to compare the use of statins in Queensland, Australia, and in Nova Scotia, Canada. Methods: Data from the Nova Scotia Pharmacare Program and the Health Insurance Commission in Australia were used to obtain dispensing data. Utilization was compared for the 5-year period from 1997 through 2001, using the World Health Organization anatomic therapeutic chemical/defined daily dose (DDD) system. Results: In the year 2001, there were 177,000 beneficiaries in the public drug plan in Nova Scotia (62% aged ≥ 65 years old) and 960,000 concession beneficiaries (pensioners and social security recipients, 61% aged ≥ 65 years) in Queensland. These 2 groups were comparable. The overall utilization of statin medications increased steadily in both areas over the study period, from 50 to 205 DDD/1000 beneficiaries per day. Comparison of the 2 growth lines showed no statistically significant differences in overall statin use despite differences in brand availabilities and policies about prescribing. In the year 2001, atorvastatin was the most commonly prescribed statin in both areas, comprising 46% of statin use in Nova Scotia and 51% in Queensland. Mean doses of each statin prescribed were slightly above the DDDs. Expenditure on statins per 1000 beneficiaries and per DDD were similar in each jurisdiction, being slightly higher in Nova Scotia. Conclusions: Despite differences in pharmaceutical reimbursement systems, use of the statins was similar in Nova Scotia and Queensland. The feasibility of the methodology was demonstrated. Future studies, including comparisons of drug utilization for other classes of drugs for which drug policies may be divergent (eg, different pricing structures or prior authorization requirements), or for which less evidence for appropriate use is available, may be useful. © 2005 Excerpta Medica, Inc.

A CFD study of biomass pyrolysis in a downer reactor equipped with a novel gas-solid separator - I:hydrodynamic performance

This study presents the first part of a CFD study on the performance of a downer reactor for biomass pyrolysis. The reactor was equipped with a novel gas-solid separation method, developed by the co-authors from the ICFAR (Canada). The separator, which was designed to allow for fast separation of clean pyrolysis gas, consisted of a cone deflector and a gas exit pipe installed inside the downer reactor. A multi-fluid model (Eulerian-Eulerian) with constitutive relations adopted from the kinetic theory of granular flow was used to simulate the multiphase flow. The effects of the various parameters including operation conditions, separator geometry and particle properties on the overall hydrodynamics and separation efficiency were investigated. The model prediction of the separator efficiency was compared with experimental measurements. The results revealed distinct hydrodynamic features around the cone separator, allowing for up to 100% separation efficiency. The developed model provided a platform for the second part of the study, where the biomass pyrolysis is simulated and the product quality as a function of operating conditions is analyzed.

Empirical study of exchange rates in Brazil, Canada and the Caribbean

This dissertation examines the monetary models of exchange rate determination for Brazil, Canada, and two countries in the Caribbean, namely, the Dominican Republic and Jamaica. With the exception of Canada, the others adopted the floating regime during the past ten years.^ The empirical validity of four seminal models in exchange rate economics were determined. Three of these models were entirely classical (Bilson and Frenkel) or Keynesian (Dornbusch) in nature. The fourth model (Real Interest Differential Model) was a mixture of the two schools of economic theory.^ There is no clear empirical evidence of the validity of the monetary models. However, the signs of the coefficients of the nominal interest differential variable were as predicted by the Keynesian hypothesis in the case of Canada and as predicted by the Chicago theorists in the remaining countries. Moreover, in case of Brazil, due to hyperinflation, the exchange rate is heavily influenced by domestic money supply.^ I also tested the purchasing power parity (PPP) for this same set of countries. For both the monetary as well as the PPP hypothesis, I tested for co-integration and applied ordinary least squares estimation procedure. The error correction model was also used for the PPP model, to determine convergence to equilibrium.^ The validity of PPP is also questionable for my set of countries. Endogeinity among the regressors as well as the lack of proper price indices are the contributing factors. More importantly, Central Bank intervention negate rapid adjustment of price and exchange rates to their equilibrium value. However, its forecasting capability for the period 1993-1994 is superior compared to the monetary models in two of the four cases.^ I conclude that in spite of the questionable validity of these models, the monetary models give better results in the case of the "smaller" economies like the Dominican Republic and Jamaica where monetary influences swamp the other determinants of exchange rate. ^

Effects of introduced moose (Alces alces) on vegetation composition, nutrient dynamics, and decomposition rates in boreal forest ecosystems in Newfoundland, Canada

Globally, consumers affect ecosystem processes including nutrient dynamics. Herbivores have been known to slow nutrient flow in boreal forest ecosystems. I examined the effects of introduced moose on disturbed forests of Newfoundland, Canada by conducting a field experiment during August - November 2014 in 20 paired moose exclosure-control plots. I tested whether moose browsing directly and indirectly affected forests by measuring plant species composition, litter quality and quantity, soil quality, and decomposition rates in areas moose exclosure-control plots. I analyzed moose effects using linear mixed effects models and found evidence indicating that moose reduce plant height and litter biomass affecting the availability of carbon, nitrogen, and phosphorus. However, plant diversity, soil quality, and litter decomposition did not differ between moose exclosures and controls. Moose in Newfoundland directly influence plant regeneration and litter biomass while indirect effects on soil ecosystems may be limited by time, disturbance, and climate.

The syntheses and characterization of nickel complexes; investigation of Ni(dppp)2 and [NiX(dppp)n]x, potentially catalytically active nickel(0)/(I) species for cross-coupling reactions

This thesis describes an investigation in which we compare Ni(0), Ni(I) and Ni(II) complexes containing 1,3-bis(diphenylphosphino)propane (dppp) as a phosphine ligand for their abilities to effect three types of cross-coupling reactions: Buchwald-Hartwig Amination, Heck-Mizoroki, and Suzuki-Miyaura cross-coupling reactions with different types of substrates. The Ni(0) complex Ni(dppp)2 is known and we have synthesized it via a new procedure involving zinc reduction of the known NiCl2(dppp) in the presence of an excess of dppp. The Ni(0) complex was characterized by NMR spectroscopy and X-ray crystallography. Since Ni(I) complexes of dppp seem unknown, we have synthesized what at this stage appear to be NiXdpppn/[NiX(dppp)n]x (X = Cl, Br, I; n = 1,2, x = 1, 2) by comproportionation of molar equivalents of Ni(dppp)2 and NiX2dppp, X= Cl, Br, I.

A State of Minds : Canada in the Information Era (Working Paper 10)

Globalization and the knowledge/ information revolution are signalling the advent of a new societal order, one with profound and pervasive implications for citizens, for markets, for governments and, therefore, for public policy. This new global order is a truly remarkable watershed in the annals of human history and, as is the case with all such great transformations, it carries with it both enormous opportunities and daunting challenges. Building on my 1999 Mabel Timlin Lecture at the University of Saskatchewan, I want to share with you my perspectives on the nature of some of these opportunities and challenges, with an eye toward drawing out the implications for the evolution of the Canadian society and economy.

An Examination of Current Approaches to Integrative Indigenous and Western Knowledge System Implementation in Water Research and Management: A Case Study Encompassing the Colonized Geographies of Canada, Australia, New Zealand, and the United States

The commodification of natural resources and the pursuit of continuous growth has resulted in environmental degradation, depletion, and disparity in access to these life-sustaining resources, including water. Utility-based objectification and exploitation of water in some societies has brought us to the brink of crisis through an apathetic disregard for present and future generations. The ongoing depletion and degradation of the world’s water sources, coupled with a reliance on Western knowledge and the continued omission of Indigenous knowledge to manage our relationship with water has unduly burdened many, but particularly so for Indigenous communities. The goal of my thesis research is to call attention to and advance the value and validity of using both Indigenous and Western knowledge systems (also known as Two-Eyed Seeing) in water research and management to better care for water. To achieve this goal, I used a combined systematic and realist review method to identify and synthesize the peer-reviewed, integrative water literature, followed by semi-structured interviews with first authors of the exemplars from the included literature to identify the challenges and insights that researchers have experienced in conducting integrative water research. Findings suggest that these authors recognize that many previous attempts to integrate Indigenous knowledges have been tokenistic rather than meaningful, and that new methods for knowledge implementation are needed. Community-based participatory research methods, and the associated tenets of balancing power, fostering trust, and community ownership over the research process, emerged as a pathway towards the meaningful implementation of Indigenous and Western knowledge systems. Data also indicate that engagement and collaborative governance structures developed from a position of mutual respect are integral to the realization of a given project. The recommendations generated from these findings offer support for future Indigenous-led research and partnerships through the identification and examination of approaches that facilitate the meaningful implementation of Indigenous and Western knowledge systems in water research and management. Asking Western science questions and seeking Indigenous science solutions does not appear to be working; instead, the co-design of research projects and asking questions directed at the problem rather than the solution better lends itself to the strengths of Indigenous science.

Études de la liaison du complexe Ku aux télomères et du délai de croissance des survivants de type I chez Saccharomyces cerevisiae

L’extrémité des chromosomes linéaires est une structure nucléoprotéique très conservée chez les organismes eucaryotes. Elle est constituée du télomère et des régions sous-télomériques répétées (STR) qui sont placées en amont du télomère. Chez la levure bourgeonnante, on trouve deux types de télomère, les télomères XY’ et les télomères X, qui se distinguent par la nature des STR positionnées en amont des répétitions télomériques. Le télomère et les STR sont liés par pas moins de dix protéines qui vont participer au maintien et à la régulation de l’extrémité chromosomique nécessaires à la stabilité du génome. Le télomère protège ainsi le chromosome de dégradations ou encore de fusions avec d’autres chromosomes. Le maintien de la taille du télomère est assuré par la télomérase, une transcriptase inverse, qui permet l’ajout de répétitions pour pallier leur perte lors de la phase de réplication durant le cycle cellulaire. Lorsque la télomérase est absente, deux types particuliers de cellules, les survivants de type I et les survivants de type II, peuvent maintenir leurs télomères grâce aux mécanismes de recombinaison homologue. Chez l’humain, les répétitions télomériques sont également liées par un certain nombre de protéines nécessaires au maintien de la stabilité de l’extrémité chromosomique. L’implication des télomères dans les processus de cancérisation, de vieillissement, mais également dans des maladies congénitales fait de cette structure un pivot dans le domaine de la recherche fondamentale. Dans 10 % des cas de cancers, l’allongement n’est pas dû à une réactivation de la télomérase comme c’est en général le cas, mais est inhérent à des processus de recombinaison homologue, comme chez la levure. Les homologies de séquences, de protéines, mais aussi de mécanismes de régulation des télomères avec les cellules humaines, font de S. cerevisiae un excellent modèle d’étude. Cette thèse se divise en trois chapitres. Les deux premiers traitent de l’interaction du complexe yKu avec les télomères de type XY’ dans le chapitre 1 puis de son interaction avec les télomères de type X dans le chapitre 2. Le chapitre 3 traite du comportement d’un type de survivant chez S. cerevisiae. Le chapitre 1 porte donc sur l’analyse des sites de liaison aux télomères XY’ du complexe yKu par la technique de ChEC in vivo. yKu intervient dans de nombreux processus de régulation des télomères, mais aussi dans un mécanisme de réparation des cassures double-brin de l’ADN (DSBs), la NHEJ (Non homologous end-joining). Les résultats présentés dans cette partie appuient un modèle dans lequel yKu aurait plusieurs sites de liaison aux télomères et dans les répétitions télomériques interstitielles. Nous supposons que la liaison du complexe se ferait lors de la formation d’une cassure de type « one-sided break » générée à la suite du passage de la fourche de réplication à l’intérieur des répétitions télomériques. Le chapitre 2 est également une étude des sites de liaison par la technique de ChEC in vivo du complexe yKu, mais cette fois-ci aux télomères X. Les observations faites dans cette partie viennent corroborer les résultats du chapitre 1 de la liaison de yKu à la jonction entre le télomère et les STRs, de plus elle met en évidence des interactions potentielles du complexe avec les éléments X laissant supposer l’existence d’un potentiel repliement du télomère sur la région sous-télomérique chez la levure. Enfin, le chapitre 3 est axé sur l’étude du comportement des survivants de type I, des cellules post-sénescences qui maintiennent leurs télomères par un processus de recombinaison homologue, le mécanisme de BIR (break-induced replication) en l’absence de télomérase. Les survivants de type I présentent une croissance lente liée à un arrêt du cycle cellulaire en phase G2/M qui dépend de la protéine de contrôle Rad9, dont l’activité est en général induite par des cassures double-brin. Ce chapitre a permis d’apporter des précisions sur la croissance lente probablement inhérente à un berceau télomérique très restreint chez ce type cellulaire.

VIOLA MUSIC FROM THE AMERICAS: MUSIC FROM CANADA, UNITED STATES, CUBA, VENEZUELA, MEXICO, AND BRAZIL

The enthusiasm towards writing music for the viola that flourished in the early 1900’s thanks to the efforts of a number of twentieth-century violists and composers rapidly spilled over to North and South America. Viola works by American and Canadian composers have already become cornerstones of the viola repertoire worldwide. On the other hand, compositions from other parts of the American continent remain lesser known outside of their country of origin. This is due in part to the less developed publishing and recording industry in these countries which makes it difficult for performers and programmers from other countries to buy or rent performing materials. As a violist born and trained in Venezuela, performing works by important Latin American composers to new audiences is deeply important to me. This dissertation was completed by performing selected works by Canadian, American, Cuban, Mexican, Brazilian, and Venezuelan composers. Composers from these countries have mixed their rich musical traditions with modern compositional techniques, creating original works that have greatly enriched the viola repertoire. This eclectic mixture of styles makes the music from Latin American composers not only very different from that of American and Canadian composers, but also very different from those of their neighboring countries. Through my three dissertation recitals, I intend to share this music with new audiences and inspire other violists to become familiar with this repertoire. The first recital includes compositions by American composers George Rochberg (1918-2015), Elliott Carter (1908-2012), and Alan Shulman (1915-2002) and Canadian composer Elizabeth Raum (b. 1945). The second recital includes works by Cuban composers Cesar Orozco (b. 1980), and Keyla Orozco (b. 1969), Venezuelan composers Aldemaro Romero (1928-2007) and Modesta Bor (1926-1998), and Venezuelan-Uruguayan composer Efrain Oscher (b. 1974). The third recital includes works by Mexican composers Carlos Chavez (1899-1978), José Pablo Moncayo (1912-1958) and Manuel M Ponce (1882-1948), and Brazilian composers Francisco Mignone (1897-1986) and Brenno Blauth (1931-1993). This music represents a bouquet of a distinctive mixture of styles from different parts of the American continent. Recordings of all three recitals can be accessed at the University of Maryland Hornabake Library.
