Maux de l'économie, mots des économistes

1990

International audience; La méthodologie économique a largement séparé les discours (hypthèses, théorie, corps de pensée) de l'action (représentée essentiellement par les applications ou les descriptions monographiques). Dans cet essai, avec la plus large prudence répondant à une démarche balbutiante, nous tentons de donner des représentations synthétiques, sur longue période, de l'évolution de la littérature économique ; ceci au moyen des méthodes usuelles de l'analyse des données. Il reste, quelque soit les résultats auxquels nous parvenons, que ce type de traintement repose sur l'hypothèse d'avoir pris en compte chaque production de littérature comme un objet statistique simple. L'applica…

Gniew człowieka w Księdze Przysłów

2018

The article is dedicated to analysis of the statements in the Book of Proverbs concerning man’s wrath. After a preliminary depiction of the attitude of man’s wrath, the author presents the basic vocabulary, namely the nouns and verbs used by the sages of Israel to convey that hard reality. In the second part of the article, after unfolding the structure of Proverbs, particular sayings mentioning the human expression of wrath are discussed. A characteristic feature of the Book of Proverbs is depicting human attitudes in parallel, thus each of the sayings is linked to a suggested positive attitude to be embraced, so as not to yield to the negative inclination toward wrath and impulsiveness. T…

The waiting time for prostate cancer treatment in Italy: analysis from the PROS-IT CNR Study.

2022

Background Prostate cancer (PCa) is the second most common neoplasm in male patients. To date, there's no certain indication about the maximum waiting time (WT) acceptable for treatment beginning and the impact on oncological and functional outcomes has not been well established. Methods Data from the National Research Council PCa monitoring multicenter project in Italy (Pros-IT CNR) were prospectively collected and analyzed. WT was defined as the time from the bioptical diagnosis of PCa to the first treatment received. Patients were divided in two groups, using a time frame of 90 days. Quality of life was measured through the Italian version of the University of California Los Angeles-Pros…

Efficient on-the-fly Web bot detection

2021

Abstract A large fraction of traffic on present-day Web servers is generated by bots — intelligent agents able to traverse the Web and execute various advanced tasks. Since bots’ activity may raise concerns about server security and performance, many studies have investigated traffic features discriminating bots from human visitors and developed methods for automated traffic classification. Very few previous works, however, aim at identifying bots on-the-fly, trying to classify active sessions as early as possible. This paper proposes a novel method for binary classification of streams of Web server requests in order to label each active session as “bot” or “human”. A machine learning appro…

NAD(P)H regeneration is the key for heterolactic fermentation of hexoses in Oenococcus oeni

2002

Oenococcus oeni (formerly Leuconostoc oenos) can perform malolactic fermentation, converting L-malate to L-lactate and carbon dioxide, in wines. The energy and redox potential required to support the growth of the micro-organism are supplied mainly by the consumption of carbohydrates via the heterolactic pathway. In the first steps of hexose metabolism two molecules of NAD(P)(+) are consumed, which must be regenerated in later reactions. The aim of this work was to test if aerobic growth of O. oeni promotes higher cell yields than anaerobic conditions, as has been shown for other lactic acid bacteria. O. oeni M42 was found to grow poorly under aerobic conditions with glucose as the only car…

Histamine, histidine, and growth-phase mediated regulation of the histidine decarboxylase gene in lactic acid bacteria isolated from wine

2006

Fermented foods are frequently contaminated by histamine that is generated by microorganisms with histidine decarboxylase activity. The ingestion of large amounts of histamine can cause serious toxicological problems in humans. A study of the effects of histamine, histidine, and growth phase on histamine production by lactic acid bacteria isolated from wine is reported here. With northern blots and specific activity analysis, we observed that histidine induces the expression of the histidine decarboxylase gene (hdc) and that histamine causes a decrease in the expression of this gene. The expression of hdc is also mediated by the bacterial growth phase. Histidine and histamine do not affect …

Saccharomyces cerevisiae-Oenococcus oeni interactions in wine: current knowledge and perspectives.

2003

Winemaking can be summarized as the biotransformation of must into wine, which is performed principally by Saccharomyces cerevisiae strains during the primary or alcoholic fermentation. A secondary fermentation, the so-called malolactic fermentation (MLF) is a biodeacidification that is often encouraged, since it improves wine stability and quality. Malolactic fermentation usually occurs either spontaneously or after inoculation with selected bacteria after alcoholic fermentation. The main organism responsible for MLF, the lactic acid bacterium Oenococcus oeni, develops in physicochemically harsh conditions, which may lead to MLF failure. Furthermore, yeast that ferment must before or toget…

Theoretical and Pragmatic Approaches of Undeclared Work in Romania

2014

Abstract Undeclared work in Romania is a very widespread phenomenon. The published information about the employment relationship worries us, having regard to the damage recorded by undeclared work. For this reason, without claiming a comprehensive approach, through this article we try to give answer to questions such as: What is undeclared work and how it is manifested in Romania? What is the level of undeclared work in Romania? What are the main causes of undeclared work? What measures can be taken to prevent, detect and stop undeclared work? What is the experience of other countries to combat undeclared work?

Game Theory and Mutual Beliefs

1995

Conventional facts are based on mutual beliefs which work as reasons for actions. The question remaining is: How can other peoples’ beliefs in something, which leads them to act accordingly, be a reason for someone else acting in a similar way? What is the compelling force of conventional facts noticed by Durkheim?
