THE MEXICAN PESO AND THE KOREAN WON REAL EXCHANGE RATES: EVIDENCE FROM PRODUCTIVITY MODELS

Using the U.S. as benchmark country, Korean data from 1970:1 to 2000:4 and Mexican data from 1983:1 to 2000:4 are decomposed into traded and non-traded sectors. We find that the traditional purchasing power parity (PPP) model performs remarkably well for the Peso and that the productivity model appears adequate for the Peso but not for the Won. As Mexican relative traded goods productivity rises, the nominal Peso appreciates (coefficients between -2.03 and -2.16). Conversely, as U.S. relative traded goods productivity rises, the Peso depreciates (coefficients between 2.06 and 2.48). Although predicting correctly the direction of change, such large magnitudes suggest only partial support for the theoretical mechanism in Mexico. Coefficients with contrary signs obtained in Korea may indicate competing models (neoclassical or Ricardian) are more appropriate to capture the relationship between productivity and exchange rates.Cointegration, Non-traded Goods, Traded Goods, Traditional PPP, Productivity Models

RL10A-3-3B high mixture ratio qualification program

The results of the high mixture ratio qualification testing of the RL10 engine for the Shuttle/Centaur program are presented. The objective of the engine qualification test was to demonstrate the suitability of the RL10A-3-3B engine for space vehicle flight by subjecting it to the testing specified in RL10A-3-3B Model Specification Number 2295 dated February 1986. The applicable section of the specification is presented. Due to payload volume advantages which can be achieved by increasing the operating mixture ratio of the RL10, a decision was made to qualify the engine to run at a higher mixture ratio. A program was created to qualify the RL10 engine for operation at 15,000 pounds thrust and a nominal 6.0 to 1 mixture ratio. This model of the engine was designated the RL10A-3-3B. The qualification program included three test series as follows: (1) hardware durability and limits test in which the engine completed 23 firings and 4605.7 seconds with 1588.7 seconds at less than 6.6 mixture ratio; (2) preliminary qualification test in which the engine completed 26 firings and 5750 seconds; and (3) qualification test in which the engine completed 26 hot firings and 5693.4 seconds with 905.9 seconds at 6.7 mixture ratio. Several changes in engine hardware were required for operation of the RL10A-3-3B engine in the Space Shuttle which include a duel pressure switch ignition, an oxidizer flow control, and helium plumbing changes

Random walks and half-lives in Chilean and Mexican peso real exchange rates: 1980-2003

Several papers have shown that high-inflation contributes to mean reversion in real exchange rates. This paper studies the Chilean peso (CLP) and Mexican peso (MXN) real exchange rates over 1980-2003. Three datasets are used: two with quarterly and monthly bilateral data (against the U.S. dollar) with consumer and producer price indices and another with monthly real effective rate exchange rates (REER). Unit root tests do not reject the root in levels for both currencies. Half-lives, however, contrast markedly: at 5 years or infinity for the Chilean peso and between 1 and 3 years for the Mexican peso. These findings suggest that the sharp depreciations in MXN and Mexico’s relatively higher inflation record may have amplified monetary forces in the dynamics of the real exchange rates.ARMA models, half-lives, random walks, real exchange rates, unit roots

Time-resolved photoelectron spectroscopy of proton transfer in the ground state of chloromalonaldehyde: Wave-packet dynamics on effective potential surfaces of reduced dimensionality

We report on a simple but widely useful method for obtaining time-independent potential surfaces of reduced dimensionality wherein the coupling between reaction and substrate modes is embedded by averaging over an ensemble of classical trajectories. While these classically averaged potentials with their reduced dimensionality should be useful whenever a separation between reaction and substrate modes is meaningful, their use brings about significant simplification in studies of time-resolved photoelectron spectra in polyatomic systems where full-dimensional studies of skeletal and photoelectron dynamics can be prohibitive. Here we report on the use of these effective potentials in the studies of dump-probe photoelectron spectra of intramolecular proton transfer in chloromalonaldehyde. In these applications the effective potentials should provide a more realistic description of proton-substrate couplings than the sudden or adiabatic approximations commonly employed in studies of proton transfer. The resulting time-dependent photoelectron signals, obtained here assuming a constant value of the photoelectron matrix element for ionization of the wave packet, are seen to track the proton transfer

Real-time observation of intramolecular proton transfer in the electronic ground state of chloromalonaldehyde: An ab initio study of time-resolved photoelectron spectra

The authors report on studies of time-resolved photoelectron spectra of intramolecular proton transfer in the ground state of chloromalonaldehyde, employing ab initio photoionization matrix elements and effective potential surfaces of reduced dimensionality, wherein the couplings of proton motion to the other molecular vibrational modes are embedded by averaging over classical trajectories. In the simulations, population is transferred from the vibrational ground state to vibrationally hot wave packets by pumping to an excited electronic state and dumping with a time-delayed pulse. These pump-dump-probe simulations demonstrate that the time-resolved photoelectron spectra track proton transfer in the electronic ground state well and, furthermore, that the geometry dependence of the matrix elements enhances the tracking compared with signals obtained with the Condon approximation. Photoelectron kinetic energy distributions arising from wave packets localized in different basins are also distinguishable and could be understood, as expected, on the basis of the strength of the optical couplings in different regions of the ground state potential surface and the Franck-Condon overlaps of the ground state wave packets with the vibrational eigenstates of the ion potential surface

Narcisismo e apassivação

Tese (doutorado)—Universidade de Brasília, Instituto de Psicologia, Departamento de Psicologia Clínica, 2008.O presente estudo parte da constatação de que em casos de pacientes psicóticos, melancólicos e deprimidos está presente o fenômeno da apassivação. Tal fenômeno implica na destituição de investimentos da posição de sujeito ativo, e, por conseqüência, no desencadeamento de uma posição objetal, na qual o psiquismo se mostra sem iniciativas que promovam uma existência mais ativa e autônoma. O objetivo principal do trabalho é, portanto, articular os adoecimentos do Eu com o processo constitutivo do narcisismo, enfocando as transformações que ocorrem nos movimentos pulsionais desses adoecimentos, por meio de uma análise lingüística que os relaciona à apassivação. A questão da apassivação e sua relação com o adoecer psíquico são analisadas, então, em três diferentes enfoques. A princípio é analisada por meio do enfoque lingüístico, ressaltando principalmente os aspectos estruturais e semânticos da regência verbal na voz passiva. Na seqüência, os aspectos constitutivos do Eu são relacionados às vozes verbais, destacando, dentro de um enfoque psicanalítico, a questão do narcisismo e da apassivação. Por último, as transformações das vozes no circuito pulsional dos adoecimentos do Eu, são analisadas por meio de exemplos clínicos. Verificou-se, por meio da análise realizada, que existe uma relação específica das vozes verbais com cada momento constitutivo do Eu, bem como uma ligação entre as formas de regressão do Eu e o modo de apassivação que ocorre nos diferentes adoecimentos narcísicos. Além disso, o dêitico relacional me, presente nos enunciados desses pacientes, pode ser considerado um indicador do processo regressivo e de apassivação que sofre o sujeito. ____________________________________________________________________________________ ABSTRACTThis work is based on the fact that the process of becoming passive is present in psychotic, melancholic and depressed patients. This process implies a lack of investments from an active subject. As a result, it causes a modification to an object position, in which the psychism remains without leading actions for an active and independent existence. The aim of this work is, therefore, to link the I illnesses with the constitutive process of narcissism. In order to do so, we emphasized the modifications which occur with the pulsional movements of these illnesses, through a linguistic analyzes, linking these illnesses with the process of becoming passive. We analyzed this process and its relationship with the psychic illness in three different approaches. First, they are studied by a linguistic aspect, highlighting mainly the structural and semantical aspects of the verbal grammar in passive voice. After, the constitutive aspects of the I are related to verbal voices, and it is highlighted, by a psychoanalytical aspect, the narcissism issue and the process of becoming passive. At last, the voices transformations in the illness pulsional circuit are analyzed through clinical examples. We verified that there is a specific relationship between the verbal voices with each constitutive moment of the I and there is a bond between the regressive forms of the I with each process of becoming passive, in different narcissic illnesses. In addition, the relational deictic me/myself, which is noticed in these patients speeches, may be considered an adviser of the regressive process and of the process of becoming passive
