We re-examine the theoretical concept of a production function for cognitive achievement, and argue that an indirect production function that depends upon the variables that constrain parents’ choices is both more tractable from an econometric point of view, and more interesting from an economic point of view than is a direct production function that depends upon a detailed list of direct input...

We investigate present some new statistical properties of order books. We analyse data from the Nasdaq and investigate (a) the statistics of incoming limit order prices, (b) the shape of the average order book, and (c) the typical life time of a limit order as a function of the distance from the best price. We also determine the ‘price impact’ function using French and British stocks, and find ...

In [3] we proposed a unified approach to addition of resistors and capacitors such that the formulæ are always simply additive. This approach has the advantage of being consistent with the intuition of students. To demonstrate the effectiveness of our approach, we proposed some problems. In this companion to the original paper, we give the solutions of the problems and we add new problems from ...

While social interactions play an important role for the evolution of bacterial siderophore production in vitro, the extent to which siderophore production is a social trait in natural populations is less clear. Here, we demonstrate that siderophores act as public goods in a natural physical environment of Pseudomonas fluorescens: soil-based compost. We show that monocultures of siderophore pro...

self confronted with a difficulty which is pithily expressed by the phrase embarrass des richesses; Deuitt, Holmes, Beyant, Eeichsen, G-ant and we hope soon to add Agnew, each admirable in its way and specially valuable from some special point of view ; all sound and complete embodiments of modern surgery. We have not included in the list of text books Paget's immortal work or Billeoth's splend...

The socio economic condition of the slum dwellers is generally poor because of the lack of basic social amenities; functional skills, proper education, source of the income, hygiene and health resources. However, slum dwellers directly or indirectly play an important role in nation building. With this point of view the study of slum dwellers becomes important. This paper attempts to demonstrate...

As part of the DocumentToText project, which is being piloted by TIME University and Horizon data society, we are working to develop an Optical Character Recognition engine to convert all scanned books that exist in Tunisian University into editable textual documents . In this article we present our approach for the development of an OCR system as well as the presentation of the utility of usin...
