La crise, l’industrie et la finance (crisis, industry and finance)
No full textCe document analyse la crise dans l’industrie. Les uns après les autres pays et branches industrielles, sont durement touchés par des suppressions d’emploi dont l’ampleur donne le vertige. Dans les années 80, le monde de l’industrie a été bouleversé. Le modèle économique des groupes industriels repose sur une combinaison des activités industrielles et financières. Ce modèle, ici détaillé, met ces groupes à la merci des marchés financiers. La crise du crédit conjuguée à la baisse du revenu disponible a transformé la crise financière en crise économique de surproduction. Cet article présente les réactions des directions de grands groupes face à la crise à partir d’exemples précis. La situation financière de ces groupes est aussi analysée, et notamment l’importance à la fois des bénéfices réalisés et du poids de leur dette. Enfin, l’auteur aborde ce qu’il estime être des facteurs d’aggravation de la crise. Une fois de plus, la variable d’ajustement des comptes des grands groupes est essentiellement la force de travail, son effectif, et son taux horaire. Denis Langlet est l’auteur du livre « L’industrie dans la tourmente de la finance » édité chez l’Harmattan en mai 2008. This article analyses the economic crisis. In each country and each industrial branch, more and more companies lay off thousand and thousand workers. During 80’s years, the industrial world was greatly upset. The culture of the firms is boundaryless, outsourcing, subcontracting, cost reduction and merger/acquisitions. This economic model put the firms under the monetary founds pression. The monetary crisis and the fall of the disposable income change the situation: financial crisis become economical and global crisis. This article presents the top management declarations about this crisis and their commitment towards shareholders. The financial situation of these groups and their huge debt are pointed. Then, the author speaks about the cost reduction policy whose the first target is the working class. Denis Langlet is the author of the book untitled “L’industrie dans la tourmente de la finance” edited by L’Harmattan in 2008 may.crisis, industry, firm, finance, shareholders
Contourographic QT interval measurement

Payment Card Network Pricing - A Theoretical Approach Analyzing the Relationship between Downstream Market Characteristics and the Merchant Usage Fee
No full textIn this thesis the model of a payment card network is constructed to explore the impact of downstream market characteristics (i.e., the market where merchants and consumers interact) on the merchant and the interchange fee, thereby extending the literature’s observations of payment systems. To accomplish this, three scenarios are analyzed: firstly, a unitary payment card network with merchants under Cournot quantity competition and, secondly, under Bertrand price competition respectively, as well as, thirdly, a multi-party payment card network with merchants under Cournot quantity competition. This study yields two significant results. Firstly, the merchant and the interchange fee are found decreasing in the consumer price elasticity, the level of product substitutability and the relative frequency of card usage. Secondly, regulating the interchange fee and the merchant fee respectively is found particularly useful since, in markets with less competition where consumers already face inefficiently high prices, the payment card fees will also tend to be higher. --Two-sided markets,Payment card networks,Platform pricing,Bertrand competition,Industrial Organization,Cournot competition
PREVENTION OF POSTISCHEMIC VENTRICULAR-FIBRILLATION LATE AFTER RIGHT OR LEFT STELLATE GANGLIONECTOMY IN DOGS
No full textTo gain insight into the differences in antiarrhythmic potential of right vs left stellate ganglionectomy, 72 dogs were randomized to either unilateral stellectomy or second intercostal space thoracotomy and left circumflex coronary arteriovenous pedicle occlusion was performed, without vagotomy, a mean of 8 weeks later under anesthesia. The type and timing of ventricular ectopic beats, including both nonsustained and sustained ventricular fibrillation, were investigated. Several covariates, including postischemic electrocardiographic changes, were considered. Both right and left stellate ganglionectomy reduced the incidence of early (0 to 10 min) (p = .004 and p = .001, respectively) and total (0 to 60 min) (p = .009 and p = .008, respectively) ischemia-induced ventricular fibrillation, and improved outcome (p = .0013 and p = .0012, respectively). Early sustained ventricular tachycardia was similarly reduced (p = .02) in both stellectomized groups. By contrast, neither the type nor the time distribution of the other forms of ventricular arrhythmias differed significantly among the randomized groups. The multivariate Cox's regression model showed that ST segment elevation at 3 min postocclusion, unilateral stellate ganglionectomy (either right or left), sex, and weight were significant independent predictors of the incidence of ventricular fibrillation during the occlusion period. Lower ST segment elevation and reduced incidence of sustained ventricular tachycardia in the early postischemic period might explain improved outcome in stellectomized dogs by Cox analysis. The side of intervention (either stellectomy or sham operation) did not influence survival; however, left-sided interventions were more effective than right-sided ones. These results confirm the previously reported antifibrillatory effect of left and indicate like effects of right stellate ganglionectomy in a randomized experimental study
The circumflex coronary artery occlusion canine model of sudden death: methodology and electrocardiographic observations.
No full textThis study deals with a left circumflex coronary artery occlusion-reperfusion canine model of sudden death using multiple electrocardiographic leads to define a subgroup of animals at high risk of ventricular fibrillation. Occlusion was followed by ventricular fibrillation in 15 of 30 animals (50\%). In the 15 dogs surviving 60 min postocclusion, reperfusion gave rise to ten cases of ventricular fibrillation (66.7\%). Thus, the total incidence of occlusion-reperfusion ventricular fibrillation was 25 of 30 (83.3\%). Electrocardiographic delta R\% changes greater than or equal to 25\% in leads 2 and 3 at both 3 and 5 min postocclusion predicted the occurrence of postocclusion ventricular fibrillation with 80\% specificity and 56\% sensitivity. However, ST segment elevation greater than or equal to 0.5 mV in the same leads at the same times predicted postocclusion ventricular fibrillation with 67\% specificity and 100\% sensitivity. When only dogs with ST segment elevation greater than or equal to 0.5 mV in leads 2 and 3 at both 3 and 5 min postocclusion were considered, ventricular fibrillation postocclusion was seen in 15 of 20 dogs (75\%) and ventricular fibrillation after reperfusion occurred in four of the remaining five animals (80\%). Thus, in the subgroup of animals presenting with ST segment elevation greater than or equal to 0.5 mV in leads 2 and 3 at both 3 and 5 min postocclusion, the overall incidence of occlusion-reperfusion ventricular fibrillation was 19 of 20 (95\%). These data may be useful in studies aimed at testing the effectiveness of drugs or other interventions in a canine model of sudden death
