A Folk Theorem for Games when Frequent Monitoring Decreases Noise

This paper studies frequent monitoring in an infinitely repeated game with imperfect public information and discounting, where players observe the state of a continuous time Brownian process at moments in time of length _. It shows that a limit folk theorem can be achieved with imperfect public monitoring when players monitor each other at the highest frequency, i.e., _. The approach assumes that the expected joint output depends exclusively on the action profile simultaneously and privately decided by the players at the beginning of each period of the game, but not on _. The strong decreasing effect on the expected immediate gains from deviation when the interval between actions shrinks, and the associated increase precision of the public signals, make the result possible in the limit.

Translating and analysing songs: three songs in the context of communist Romania

Songs were the means used by the Romanian Communist Party to ‘educate’ Romanians. Through them, Romanians were told what they had to appreciate, how grateful they were supposed to be to the regime, how great President Ceausescu was and how they had to work harder and harder so that they could be even better Communists. This paper comprises the translation of three songs composed, performed and broadcast in Communist Romania and their analysis from the point of view of communication. In translating the song, I have chosen to translate closest to the original possible meaning and meanwhile to respect to the best of my ability Low’s ‘pentathlon principle’: singability, rhyme, rhythm, naturalness and fidelity to the sense of the source text

Assessing the Precision of Compositional Data in a Stratified Double Stage Cluster Sample: Application to the Swiss Earnings Structure Survey

Precision of released figures is not only an important quality feature of official statistics,it is also essential for a good understanding of the data. In this paper we show a casestudy of how precision could be conveyed if the multivariate nature of data has to betaken into account. In the official release of the Swiss earnings structure survey, the totalsalary is broken down into several wage components. We follow Aitchison's approachfor the analysis of compositional data, which is based on logratios of components. Wefirst present diferent multivariate analyses of the compositional data whereby the wagecomponents are broken down by economic activity classes. Then we propose a numberof ways to assess precision

Mastoparan, a novel mitogen for Swiss 3T3 cells, stimulates pertussis toxin-sensitive arachidonic acid release without inositol phosphate accumulation

Mastoparan, a basic tetradecapeptide isolated from wasp venom, is a novel mitogen for Swiss 3T3 cells. This peptide induced DNA synthesis in synergy with insulin in a concentration-dependent manner; half-maximum and maximum responses were achieved at 14 and 17 microM, respectively. Mastoparan also stimulated DNA synthesis in the presence of other growth promoting factors including bombesin, insulin-like growth factor-1, and platelet-derived growth factor. The synergistic mitogenic stimulation by mastoparan can be dissociated from activation of phospholipase C. Mastoparan did not stimulate phosphoinositide breakdown, Ca2+ mobilization or protein kinase C-mediated phosphorylation of a major cellular substrate or transmodulation of the epidermal growth factor receptor. In contrast, mastoparan stimulated arachidonic acid release, prostaglandin E2 production, and enhanced cAMP accumulation in the presence of forskolin. These responses were inhibited by prior treatment with pertussis toxin. Hence, mastoparan stimulates arachidonic acid release via a pertussis toxin-sensitive G protein in Swiss 3T3 cells. Arachidonic acid, like mastoparan, stimulated DNA synthesis in the presence of insulin. The ability of mastoparan to stimulate mitogenesis was reduced by pertussis toxin treatment. These results demonstrate, for the first time, that mastoparan stimulates reinitiation of DNA synthesis in Swiss 3T3 cells and indicate that this peptide may be a useful probe to elucidate signal transduction mechanisms in mitogenesis.

Using Songs in Primary Education: Advantages and Challenges

Aquesta recerca està basada en l’observació de les cançons per aprendre i ensenyar la llengua anglesa en l’etapa d’Educació Primària. S’analitza la cançó com un recurs eficaç per aprendre aquesta llengua, així com també s’observen els avantatges i desavantatges que es poden trobar en l’ús de les cançons a les aules de Primària. A partir d’una aplicació pràctica també s’estudia la validesa d’aquest recurs en el primer i darrer curs de la Primària. A més a més, es mesura la motivació que mostren els alumnes davant d’aquesta eina d’aprenentatge. Finalment, es presenten els resultats obtinguts en l’aplicació pràctica que s’ha portat a terme en una escola i les conclusions que s’extreuen a partir de la justificació teòrica i els resultats obtinguts a partir de les sessions pràctiques.
