Risk adverse individuals demand a sickness insurance to cover the risk of income loss due to work incapacity. Since health or sickness is not easy to observe, there is asymmetric information causing the well-known problems with adverse selection and moral hazard. Furthermore, sickness, with resulting inability to work, is to some extent private information hidden to the insurer. One effect is that

A producer-independent, problem-oriented, group-education programme with 2-day meetings on drug treatment in primary health care (PHC) was developed and evaluated. Initially, it was tested on a selected group of general practitioners (district physicians), using a non-exposed group as control. A comprehensive questionnaire was used to test changes in attitudes. There was a significant change in at

Popular Abstract in SwedishEn av de viktigaste forskningsfrågorna inom matematikutbildning handlar om förståelse. Det huvudsakliga syftet med den här avhandlingen har varit att nå insikt i olika förståelseformer i skolmatematik och former av lärandeidentiteter i två lärandemiljöer. Avhandlingens specifika fokus var flexibla sätt att urskilja delar och avgränsa helheter och undersöka hur lärande inA central question in mathematics education research concerns understanding. The main objective of the present thesis has been to obtain insights into flexible modes of knowing in school mathematics in two school class contexts, and how these relate to modes of being a learner in these contexts, with specific focus on learners’ flexible ways of discerning parts and delimiting wholes, and how they

Not all areas in value theory are battlegrounds. We find, for instance, a strong consensus when it comes to whether or not values are so-called supervenient properties, i.e., properties that accrue to the value bearer in virtue of some or all of its other kinds of (subvenient) properties. These ‘other properties’ are often assumed to belong (at least at some basic level) to the object’s so-called

Plasminogen activator inhibitor-1 (PAI-1) functions as an important regulator of fibrinolysis by inhibiting both tissue-type and urokinase-type plasminogen activator. PAI-1 is produced by smooth muscle cells (SMCs) in atherosclerotic arteries, but the mechanisms responsible for induction of PAI-1 in SMCs are less well understood. In cultured human aortic SMCs, PAI-1 mRNA expression and protein sec

Interest in learning in mature adulthood has become increasingly important as attention has been focused on what is seen to be an impending crisis in the near future, i.e., shortage of labour due to the ever-growing number of elderly and decreasing nativity rates. In some circles "alarmist demographics" have overshadowed an arguably more important concern, that of providing for aging individuals'

In this lecture, we will discuss the emergence of the semiotic function, both ontogenetically and phylogenetically, and we will consider the part played by the picture sign in this development. In order to demonstrate that pictures are indeed signs, we will explore the basic elements of the sign presupposed but never put into focus neither by Saussure nor by Peirce. Indeed, explorations in the psy
