L'aperception de soi chez shihab al-din al-suhrawardi et l'heritage avicennien

Avicenna (d. 1037) bequeathed the Arabic philosophical tradition with an aporia : self-knowledge is conceived, at times, in terms of intellection, at other times, in terms of apperception. In his Book of Discussions and Book of Notes, Avicenna has lengthy discussions on apperception, defined as a direct ontological mode of knowledge. Heir to this tradition, Shihāb al-Dīn al-Suhrawardī (d. 1191) moved away from the first conception of self-knowledge as intellection to adopt the second conception of an apperception of the self as a direct, intuitive and "presential (hcombining dot belowudcombining dot belowūrī)" perception, and which he defended with four types of arguments.

Pharmacokinetic software for the health sciences - Choosing the right package for teaching purposes

Computer assisted learning has an important role in the teaching of pharmacokinetics to health sciences students because it transfers the emphasis from the purely mathematical domain to an 'experiential' domain in which graphical and symbolic representations of actions and their consequences form the major focus for learning. Basic pharmacokinetic concepts can be taught by experimenting with the interplay between dose and dosage interval with drug absorption (e.g. absorption rate, bioavailability), drug distribution (e.g. volume of distribution, protein binding) and drug elimination (e.g. clearance) on drug concentrations using library ('canned') pharmacokinetic models. Such 'what if' approaches are found in calculator-simulators such as PharmaCalc, Practical Pharmacokinetics and PK Solutions. Others such as SAAM II, ModelMaker, and Stella represent the 'systems dynamics' genre, which requires the user to conceptualise a problem and formulate the model on-screen using symbols, icons, and directional arrows. The choice of software should be determined by the aims of the subject/course, the experience and background of the students in pharmacokinetics, and institutional factors including price and networking capabilities of the package(s). Enhanced learning may result if the computer teaching of pharmacokinetics is supported by tutorials, especially where the techniques are applied to solving problems in which the link with healthcare practices is clearly established.
