Monetary circulation, the paradox of profits, and the velocity of money
2007
Recent papers have reconsidered the paradox of profits, that is the difficulty to explain how monetary profits can be generated when firms borrow only the wage bill to finance their production. In this article, we use a stock-flow consistent approach give a solution to this paradox assuming that, when firms sell goods at prices which exceed their unit costs, the realised monetary profits are not used to pay back banks. These profits then remain in the circuit, allowing additional transactions. In a sense, profits result from their own expenditure. According to this interpretation, the velocity of money is higher than one because some monetary units are used in several transactions of goods.
Texture et paradoxes auditifs dans la musique récente de Michaël Levinas
2020
Parmi les courants musicaux apparus après 1945, le spectralisme a été celui dont les fondements théoriques, les techniques d’écriture et les sources d’inspiration ont été le plus fécondés par les recherches en acoustique, en psychoacoustique et en perception de la musique. Les questionnements musicaux de Michaël Levinas, comme ceux de Grisey, Murail, Dufourt, Saariaho, Hurel, Dalbavie, Maresz et d’autres, se sont nourris de notions telles que spectre, transitoires, résonance, battements, sons de combinaison, inharmonicité, rugosité, seuil perceptif,masquage, effet Doppler, etc. Cependant, s’il partage avec ses collègues ce socle de connaissances, elles ne l’ont pas conduit aux mêmes solutio…

A search for beta-lactamase in chlamydiae, mycoplasmas, planctomycetes, and cyanelles: bacteria and bacterial descendants at different phylogenetic p…
2000
Bacteria from different phylogenetic positions such as chlamydiae, mycoplasmas, planctomycetes and also endosymbiotic murein-containing cyanelles were investigated for the production of beta-lactamases. No beta-lactamase activity was found in bacteria lacking murein such as Chlamydia pneumoniae, Mycoplasma pneumoniae, Pirellula marina and Planctomyces maris. In the murein-containing cyanelles of Cyanophora paradoxa no beta-lactamase activity could be detected.
Patterns of international capital flows and their implications for developing countries
2017
According to standard economic theory, capital should flow from rich to poor countries. However, a reverse pattern has prevailed in the world economy. This is the so-called Lucas paradox. In addition, it has been shown that, counterintuitively, there is a negative correlation between capital inflow and productivity growth across developing countries. This is the so-called allocation puzzle. This review sheds light on the following questions: “What are the patterns of international capital flows in the world economy?”, “What are the most plausible explanations for these patterns?”, and “What are the possible implications of these developments for developing countries?” In addition, the curre…
IS evolution benefit assessment: Challenges with economic investment criteria
2007
Maintenance and system evolution activities have a significant role in the information system (IS) life cycle. It has been estimated that approximately 80% of the total IT expenses are allocated for maintenance activities [20]. According to Lehman’s first law, maintenance is necessary, because software needs to be continuously improved or it will get out of date and cannot respond to the requirements of its environment [19]. Despite the importance of IS evolution investments, there is a gap between the IT related costs and company profitability [27]. Brynjolfssen [10] described this as a productivity paradox: information technology utilization has increased since the 70’s but simultaneously…
Headache in cerebrospinal fluid volume depletion syndrome: A case report
2006
Cerebrospinal fluid (CSF) volume depletion syndrome is due to leakage of cerebrospinal fluid through lesions of the dural sac at the level of the cranial base or of the spine. When past medical history is negative for recent trauma or surgery, the term spontaneous intracranial hypotension (SIH) is used. SIH is characterized clinically by orthostatic headache, neck pain, nausea, emesis, horizontal diplopia, tinnitus, plugged ear, hearing difficulties, blurring of vision, facial numbness, and upper limb radicular symptoms. In SIH, brain and cervical MR scans show a diffuse pachymeningeal gadolinium enhancement that ends at the site of CSF leakage. The application of epidural blood patches has…
