Chute Losses Aren't Accidents! Most Injuries can be Avoided. Here's How to Rate the Performance of Your Chute and Crew

The conclusion of the article reads "good handling during processing and re-implanting could mean the difference between a going operation and financial disaster. But it's up to you to make certain your crew understands and follows proper chute practices. When they do, it will mean more money in your pocket."

The Transformation Problem : an Aleternative Solution with an Identical Aggregate Profit Rate in the Labor value and the Monetary Space.

The aim of this paper is to demonstrate that, even if Marx's solution to the transformation problem can be modified, his basic conclusions remain valid. the proposed alternative solution which is presented hare is based on the constraint of a common general profit rate in both spaces and a money wage level which will be determined simultaneously with prices.

The Inflation Bias When the Central Bank Targets, the Natural Rate of Unemployment

This paper studies the proposition that an inflation bias can arise in a setup where a central banker with asymmetric preferences targets the natural unemployment rate. Preferences are asymmetric in the sense that positive unemployment deviations from the natural rate are weighted more (or less) severely than negative deviations in the central banker's loss function. The bias is proportional to the conditional variance of unemployment. The time-series predictions of the model are evaluated using data from G7 countries. Econometric estimates support the prediction that the conditional variance of unemployment and the rate of inflation are positively related.

Explaining the Transition Between Exchange Rate Regimes

This paper studies the transition between exchange rate regimes using a Markov chain model with time-varying transition probabilities. The probabilities are parameterized as nonlinear functions of variables suggested by the currency crisis and optimal currency area literature. Results using annual data indicate that inflation, and to a lesser extent, output growth and trade openness help explain the exchange rate regime transition dynamics.

Temporary Natural Resource Cartels

We analyze the behavior of a nonrenewable resource cartel that anticipates being forced, at some date in the future, to break-up into an oligopolistic market in which its members will then have to compete as rivals. Under reasonable assumptions about the value function of the individual firms in the oligopolistic equilibrium that follows the break-up, we show that the cartel will then produce more over the same interval of time than it would if there were no threat of dissolution, and that its rate of extraction is a decreasing function of the cartel's life; that there are circumstances under which the cartel will attach a negative marginal value to the resource stocks, in which case the rate of depletion will be increasing over time during the cartel phase; that, for a given date of dissolution, the equilibrium stocks allocated to the post-cartel phase will increase as a function of the total initial stocks, whereas those allocated to the cartel phase will increase at first, but begin decreasing beyond some level of the total initial stocks.

The Exchange Rate in a Dynamic-Optimizing Current Account Model with Nominal Rigidities: a Quantitative Investigation.

This paper studies a dynamic-optimizing model of a semi-small open economy with sticky nominal prices and wages. the model exhibits exchange rate overshooting in response to money supply shocks. the predicted variability of nominal and real exchange rates is roughly consistent with that of G7 effective exchange rates during the post-Bretton Woods era.

Cardiovascular effects of a medetomidine constant rate infusion at different dose levels in anaesthetized dogs

Les effets cardiovasculaires des alpha-2 agonistes, particulièrement importants chez les chiens, limitent leur utilisation en pratique vétérinaire. La perfusion à débit constant (PDC) de ces drogues, comme la médétomidine (MED) permettrait un contrôle plus précis de ces effets. Les effets hémodynamiques de plusieurs doses de MED en PDC ont été évalués chez le chien. Lors de cette étude prospective, réalisée en double aveugle, 24 chiens en santé, ont reçu de façon aléatoire une des 6 doses de MED PDC (4 chiens par groupe). Les chiens ont été ventilés mécaniquement pendant une anesthésie minimale standardisée avec de l’isoflurane dans de l’oxygène. Une dose de charge (DC) de médétomidine a été administrée aux doses de 0.2, 0.5, 1.0, 1.7, 4.0 ou 12.0 µg/kg pendant 10 minutes, après laquelle la MED PDC a été injectée à une dose identique à celle de la DC pendant 60 minutes. L’isoflurane a été administré seul pendant une heure après l’administration d’une combinaison d’ISO et de MED PDC pendant 70 minutes. La fréquence cardiaque (FC), la pression artérielle moyenne (PAM) et l’index du débit cardiaque (IC) ont été mesurés. Des prélèvements sanguins ont permis d’évaluer le profil pharmacocinétique. D’après ces études, les effets hémodynamiques de la MED PDC pendant une anesthésie à l’isoflurane ont été doses-dépendants. L’IC a diminué progressivement alors que la dose de MED augmentait avec: 14.9 (12.7), 21.7 (17.9), 27.1 (13.2), 44.2 (9.7), 47.9 (8.1), and 61.2 (14.1) % respectivement. Les quatre doses les plus basses n’ont provoqué que des changements minimes et transitoires de la FC, de la PAM et de l’IC. La pharmacocinétique apparaît clairement dose-dépendante. De nouvelles expériences seront nécessaires afin d’étudier l’utilisation clinique de la MED PDC.
