The paper analyses the scientific research production of more than a thousand faculty members of Louis Pasteur University, large and well ranked in Europe. We take account of individual and collective determinants to explain individual productivity in terms of intensity and quality. We find that individual variables related to the position occupied are significant. The size of the lab plays neg...

In the present work, ribosomes assembled in bacterial cells in the absence of essential ribosomal protein L5 were obtained. After arresting L5 synthesis, Escherichia coli cells divide a limited number of times. During this time, accumulation of defective large ribosomal subunits occurs. These 45S particles lack most of the central protuberance (CP) components (5S rRNA and proteins L5, L16, L18,...

The controversy over whether and how much to charge for health products in the developing world rests, in part, on whether higher prices can increase use. We test this hypothesis in a field experiment in Zambia using door-to-door marketing of a home water purification solution. Our methodology separates the screening effect of prices (charging more changes the mix of buyers) from the psychologi...

Due to EU law, European citizens enjoy one of the highest worldwide food safety standards. Along the entire food supply chain, mandatory controls are made to ensure that plant and animal products healthiness and food and feed safety are properly labeled and comply with the strictly EU rules. The process of review of European legislation began with the promulgation of the Regulation 178/2002/EC ...

The paper is an exploratory study of science parks in the United States. It models the history of science parks as the diffusion of an innovation that was adopted at a rapid and increasing rate in the early 1980s, and since then at a decreased rate. It models the growth of a science park once established, showing significant effects on growth for the proximity to universities and other resource...

abstract this article aims to provide theoretical model for analyzing challenge of asymmetric information in the third sector of economy (which is the most important challenge, preventing the growth and development of third sector), using the theoretical foundation of contract theory and incentive theory with regard to the special characteristics of third sector derived by its special structure...

Anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV) is a severe condition encompassing two major syndromes – granulomatosis with polyangiitis (formerly known as Wegener’s--GPA) and microscopic polyangiitis (MPA). Its etiology is unknown, and whether it is a single disease entity, and the role of ANCA in its pathogenesis, are debated. To investigate the genetic basis of AAV a g...

Bacteria respond dynamically to the changes in zinc availability. Repression by the Bacillus subtilis transcription factor Zur requires Zn(II), which binds with negative cooperativity to two regulatory sites per dimer to form, sequentially, Zur2:Zn3 and Zur2:Zn4 forms of the repressor. Here we show that, as cells transition from zinc sufficiency to deficiency, operons regulated by Zur are derep...

We examine the use of subsidies to R&D in a mixed and a private duopoly market. We show that the socially optimal R&D subsidy is increasing in the degree of spillovers but it is lower in the private duopoly. The optimal R&D subsidy leads to an increase in total R&D and production, however, it does not lead to the equalisation of per …rm output and therefore to an e¢ cient distribution of produc...

In this paper, I argue that because nonprofit organizations rely disproportionately on intrinsically motivated employees, they provide a particularly interesting context for examining the relationship between wage dispersion and employee motivation. If certain hypotheses put forth in the literature on psychology and employee motivation are correct, then wage dispersion should be less apparent i...
