Central bank independence : a critical view
No full textWhile expansive literature on central bank independence contains some criticisms to the independent central bank quasi-paradigm, few critical analyses have been undertaken in the years between Friedman (1962) and Posen (1994). The author extends Posen's analysis to developing countries, discussing more broadly and systematically the reasons why merely instituting an independent central bank may not bring about its professed benefits, especially in developing countries. The author argues that widely reported empirical tests that are purported to support the central bank independence proposition are plagued by potential problems of simultaneity, reverse causality, missing variables, and measurement errors. Yet one can not make positive recommendations about institutional arrangements for central banks if causality relations are not well established. Institutions are shaped by a country's record of and preferences for inflation and may have little influence on them. The author also argues that the purported benefits of an independent central bank may be eroded by conflicts between fiscal and monetary policy and by inherent problems of central bank institutional design (especially mechanisms for board appointments, public accountability, and budgetary control). If these institutional problems are not solved, problems of dynamic inconsistency traditionally associated with monetary policy are not eliminated,but merely transformed. The author suggests that the benefits of central bank independence are less likely obtained in less developed countries with shallow financial markets. Accordingly, central bank independence should be granted at a later stage in a country's financial sector development. If a less developed country seeks to establish a low-inflation path, it should concentrate on instituting financial policy reforms (such as liberalization and privatization) that bolster opposition to inflation rather than easily reversible and practically meaningless changes in legal and institutional structures. This will better ensure the sustainability -- and hence the credibility -- of the government's anti-inflation stance. Fiscal policy is often at the root of macroeconomic disturbances in developing countries. Fiscal policy is more deserving of special protection from politics because of fiscal dominance over monetary policy and its greater vulnerability to private interests. The author suggests that the solution might be to make fiscal policy less susceptible to political pressures by creating an independent fiscal board. Tying the fiscal hands of government may seem a far-fetched idea. But would it not make more sense to force discipline on fiscal policy directly rather than indirectly through monetary policy?Economic Theory&Research,National Governance,Banks&Banking Reform,Economic Stabilization,Macroeconomic Management

Vision-based Integrated Navigation System and Optimal Allocation in Formation Flying
No full textThis article proposes an integrated navigation system for multiple micro aerial vehicles flying in formation. A data fusion algorithm uses measurements from an inertial measurement unit, a GPS receiver and a camera allowing to use the positioning information of the surrounding vehicles to improve its estimation. A measure of the navigation performance of the formation is defined. Based on such measure, the position where each vehicle should be located in the formation is studied to guarantee the best overall navigation quality.Fil: Giribet, Juan Ignacio.

Quaternions and Dual Quaternions: Singularity-Free Multirobot Formation Control
No full textCluster space control is a method of multirobot formation keeping that considers a group of robots to be a single entity, defining state variables to represent characteristics of the group, such as position, orientation, and shape. This technique, however, suffers from singularities when a minimal state representation is used. This paper presents three alternative implementations of this control approach that eliminate singularities through changes in the control architecture or through redundant formation definitions. These proposed solutions rely on quaternions, dual quaternions, and control implementations that produce singularity-free trajectories while maintaining a cluster level abstraction that allows for simple specification and monitoring. A key component of this work is a novel concept of representing formation shape parameters with dual quaternions. Simulation results show the feasibility of the proposed solutions and illustrate their differences and limitations.Fil: Mas, Ignacio Agustin.

Regulating New Banking Models to Bring Financial Services to All
No full textIn parts of Africa, only one in five people have access to traditional banking services. In Latin America only one in three do. Claire Alexandre, Ignacio Mas, and Daniel Radcliffe of the Bill and Melinda Gates Foundation say this need not be the case. The technology exists to make banking available at traditional retail outlets and thus spread access dramatically. For this to happen, regulations need changing. They tell us what they would do.
Adaptive Center-of-Mass Relocation for Aerial Manipulator Fault Tolerance
No full textThis work proposes a fault tolerant aerial manipulator based on a standard hexarotor vehicle, which is able to maintain independent control of torque and vertical thrust in case of motor failure by adequately changing the manipulator configuration and therefore modifying the position of the system's center of mass. By analyzing the disturbance torque that the manipulator exerts on the vehicle, conditions to achieve stable flight and operation limits are established. To provide an experimental proof of concept, several flights are performed, both in indoor and outdoor environments, for different size and weight of manipulators.Fil: Pose, Claudio Daniel.

Letter from Mas Sakai to Sakai family, October 12, 1942
No full textTwo letters from Mas Sakai to the Sakai Family, sent from Tanforan Assembly Center, informing the family that he will be leaving for Utah the following day. The letter is laced with sarcasm as Sakai describes living conditions at Tanforan ("it wouldn't be right if I called it a concentration camp would it? After all we get the freedom of the track, don't we?"), and incarcerees' expectations of life at Topaz ("we all look to Utah with a song in our hearts (a funeral march) for there are our golden opportunities. Wonderful, trackless, sand to plant in, and cool refreshing salt water to drink. We especially look forward to the toilets (no seats)").Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide
