PRICE VERSUS QUOTA REDUCTIONS: U.S. FLUE-CURED TOBACCO POLICY
Declining domestic cigarette consumption, increased global competition, and loss of import restrictions indicate decreased demand for U.S. flue-cured tobacco. The effects of 10% declines in domestic and export demand are evaluated under a policy of reducing quota to maintain price versus a policy of allowing price to fall to maintain quota. Changes in prices, quantities, revenues, and economic rents are simulated. Losses to nonfarming quota owners are minimized under a policy of price maintenance, while losses in revenues to tobacco-producing areas are minimized by a policy of quota maintenance. Aggregate losses to tobacco growers are greater under a policy of quota maintenance.Flue-cured, Policy, Price reduction, Quota, Tobacco, Agricultural and Food Policy,

“Pistol Fever”: Regulating Revolvers in Late-Nineteenth-Century Canada
This paper examines the debates over the regulation of pistols in Canada from confederation to the passage of nation’s first Criminal Code in 1892. It demonstrates that gun regulation has long been an important and contentious issue in Canada. Cheap revolvers were deemed a growing danger by the 1870s. A perception emerged that new forms of pistols increased the number of shooting accidents, encouraged suicide, and led to murder. A special worry was that young, working-class men were adopting pistols to demonstrate their manliness. Legislators responded to these concerns, but with trepidation. Parliament limited citizens’ right to carry revolvers, required retailers to keep records of gun transactions, and banned the sale of pistols to people under 16 years of age. Parliamentarians did not put in place stricter gun laws for several reasons. Politicians doubted the ability of law enforcement officials to effectively implement firearm laws. Some believed that gun laws would, in effect, only disarm the law abiding. In addition, a number of leading Canadian politicians, most importantly John A. Macdonald, suggested that gun ownership was a right of British subjects grounded in the English Bill of Rights, albeit a right limited to men of property.Le présent article porte sur les débats entourant la réglementation des pistolets au Canada depuis la confédération jusqu’à la promulgation du premier Code criminel en 1892. Il démontre que la réglementation des armes à feu est un point litigieux et important au Canada depuis longtemps. À partir des années 1870, en effet, les révolvers bon marché sont considérés comme étant un danger croissant. L’idée se profile que les nouvelles sortes de pistolets augmentent le risque de fusillades, incitent au suicide et favorisent le meurtre. On s’inquiète particulièrement de l’adoption du pistolet par les jeunes hommes de la classe ouvrière pour afficher leur masculinité. Le législateur réagit à ces préoccupations, mais avec appréhension. Le parlement intervient pour limiter le droit des citoyens de porter des armes de poing, pour exiger que les commerçants tiennent des relevés de transactions et pour interdire la vente de pistolets aux moins de seize ans. Or, les parlementaires n’imposent pas de lois plus strictes pour plusieurs raisons, entre autres parce qu’ils doutent de la capacité des agents de la paix de les appliquer efficacement. Certains sont d’avis qu’une telle législation n’aurait pour effet que de désarmer les citoyens respectueux des lois. Par ailleurs, plusieurs dirigeants politiques canadiens de premier plan, dont John A. Macdonald, pensent que tout sujet britannique a le droit de posséder une arme en vertu du Bill of Rights anglais, même si ce droit est limité aux propriétaires fonciers
Near-Infrared Spectroscopy of the Bright Kuiper Belt Object 2000 EB173
We have obtained a near-infrared spectrum of the bright Kuiper Belt object 2000 EB173; the spectrum appears featureless. The spectrum has a sufficient signal-to-noise ratio to rule out the 1.5 and 2.0 ÎĽm absorption from water ice even at the low level seen in the Centaur Chariklo. In addition, we can rule out a 2.3 ÎĽm absorption at the level seen in the Centaur Pholus
Molecular Identification of Eimeria Species in Broiler Chickens in Trinidad, West Indies
Coccidiosis is an intestinal disease of chickens of major economic importance to broiler industries worldwide. Species of coccidia found in chickens include Eimeria acervulina, Eimeria brunetti, Eimeria maxima, Eimeria mitis, Eimeria necatrix, Eimeria praecox, and Eimeria tenella. In recent years, polymerase chain reaction (PCR) has been developed to provide accurate and rapid identification of the seven known Eimeria species of chickens. The aim of this study was to use species-specific real-time PCR (qPCR) to identify which of the seven Eimeria species are present in Trinidad poultry. Seventeen pooled fecal samples were collected from 6 broiler farms (2–5 pens per farm) across Trinidad. Feces were also collected from birds showing clinical signs of coccidiosis in two live bird markets (pluck shops). qPCR revealed the presence of five species of Eimeria (E. acervulina, E. maxima, E. mitis, E. necatrix, and E. tenella), but not E. brunetti or E. praecox. Mixed infections were detected on all broiler farms, and DNA of two highly pathogenic Eimeria species (E. tenella and E. necatrix) was detected in feces taken from clinically sick birds sampled from the two pluck shops
Three Cheers for Lord Denman: Reformers, the Irish, and Jury Reforms in Nova Scotia, 1833-1845
This article explores the important place of the jury in the relationship between law, politics, and state in pre-Confederation Nova Scotia. The legislature responded to fears of jury packing by creating more complex procedures for jury selection. These jury selection systems relied for their implementation on committees composed of magistrates and sheriffs, officials who proved unreliable instruments for carrying out a more bureaucratic state policy. Juries also reflected, and influenced, debates about political parties, libel, and the public sphere. In the 1840s, Irish immigrants to Nova Scotia drew upon their experience of packed juries in Ireland to complain that they were systematically excluded from jury service. Political reformers also asserted that officials packed juries against them with their political opponents, especially in high profile libel cases in which tories attempted to silence the increasingly critical reform press. These libel cases highlighted the role of the jury in protecting freedom of the press and therefore reformers’ ability to challenge the tory leadership of the colony. The fierce complaints over jury selection irregularities led to the passage of reform legislation, though a final solution to the politicization of juries remained elusive with the emergence and acceptance of political parties in Nova Scotia.L’article suivant analyse le rôle important du jury au regard de la loi, de la politique et de l’État, dans la Nouvelle-Écosse d’avant la Confédération. Afin d’éviter qu’un jury soit noyauté, l’assemblée législative élabora des procédures complexes pour mieux encadrer la sélection des jurés. La mise en oeuvre de ces procédures relevait de comités composés de magistrats et de shérifs; ces représentants officiels se révélèrent toutefois peu fiables pour appliquer les mesures bureaucratiques instaurées par l’État. Les jurés ne restaient pas imperméables aux débats sur les partis politiques, sur la diffamation et sur les questions relevant du domaine public. Dans les années 1840, les immigrants irlandais installés en Nouvelle-Écosse, forts de leur expérience de noyautage de jury en Irlande, se plaignirent qu’ils n’étaient jamais appelés à faire partie d’un jury. Des réformistes politiques affirmèrent aussi que des représentants officiels choisissaient des jurés défavorables à leur cause, surtout lorsqu’il s’agissait de cas majeurs de poursuite en diffamation, les torys se servant de cette tribune pour tenter de museler une presse réformiste de plus en plus critique. Ces procès en diffamation soulignaient l’importance du rôle du jury dans la protection de la liberté de la presse et montraient conséquemment que les réformistes avaient les moyens d’ébranler le leadership des torys dans la colonie. Les virulentes dénonciations des irrégularités dans la sélection des jurés débouchèrent sur l’adoption d’une loi réformiste; le problème de la politisation des jurés resta cependant difficile à régler entièrement à cause de la montée et de la reconnaissance des partis politiques en Nouvelle-Écosse
Torque vectoring to maximize straight-line efficiency in an all-electric vehicle with independent rear motor control
BEVs are a critical pathway towards achieving energy independence and meeting greenhouse and pollutant gas reduction goals in the current and future transportation sector [1]. Automotive manufacturers are increasingly investing in the refinement of electric vehicles as they are becoming an increasingly popular response to the global need for reduced transportation emissions. Therefore, there is a desire to extract the most fuel economy from a vehicle as possible. Some areas that manufacturers spend much effort on include minimizing the vehicle’s mass, body drag coefficient, and drag within the powertrain. When these values are defined or unchangeable, interest is driven to other areas such as investigating the control strategy of the powertrain. If two or more electric motors are present in an electric vehicle, Torque Vectoring (TV) strategies are an option to further increase the fuel economy of electric vehicles. Most of the torque vectoring strategies in literature focus exclusively on enhancing the vehicle stability and dynamics with few approaches that consider efficiency or energy consumption. The limited research on TV that addresses system efficiency have been done on a small number of vehicle architectures, such as four independent motors, and are distributing torque front/rear instead of left/right which would not induce any yaw moment. The proposed research aims to address these deficiencies in the current literature. First, by implementing an efficiency-optimized TV strategy for a rear-wheel drive, dual-motor vehicle under straight-line driving as would be experienced in during the EPA drive cycle tests. Second, by characterizing the yaw moment and implementing strategies to mitigate any undesired yaw motion. The application of the proposed research directly impacts dual-motor architectures in a way that improves overall efficiency which also drives an increase in fuel economy. Increased fuel economy increases the range of electric vehicles and reduces the energy demand from an electrical source that may be of non-renewable origin such as coal
