An Analysis of Sick Leave in Sweden using Panel Data 1985-1997

Since the beginning of the 1990's, sick leave benefits accruing from the tax-financed Swedish social security insurance have been reduced a number of times. In this paper we use data from the survey on the Household Market and Non-market activities to estimate a fixed effects negative binomial model. We find a direct relationship between the rate of compensation and the amount of sick leave taken

Interlaboratory tests on thermal foot models

In order to compare measurements in different laboratories and with different models and measuring principles a small Round Robin test was suggested. 12 test institutions were able to join the study (with foot model sizes from 254 mm to 275 mm and test boot sizes from 41 to 44). We got also a declaration of interest from 2 other institutes that were not able to carry out the tests now. A database

The specificities of radical innovation

In this paper, we investigate a special case of new product development (NDP), that of radical innovation. When a company desires to go outside a current saturated market, it is necessary to offer a new product which is radically different from the competition. If successful, the offering will create a new market that the company can expect to dominate a least for a while until the competition str

Konversion

This book chapter is a short presentation of different understandings of the concept of conversion, research on conversion, and the complexity of using this concept to describe religious mobility today. This applies not least to conversion where religions other than Christianity are involved. Conversion is also discussed in relation to secularisation and individualisation of religion.

Physics of Viral Infectivity: Energetics of Genome Ejection

Popular Abstract in Swedish Virala infektioner är och har varit ett stort hälsoproblem för mänskligheten. Många av de sjukdomar som förorsakas av virus är obotliga och spridningen är oftast snabb (ett exempel är HIV). Förutom att direkt förorsaka olika sjukdomstillstånd har virus också påvisats vara orsak till olika former av cancer. Under de senaste åren har dock forskare försökt att börja använAll viruses that infect bacteria, plant, or animal cells involve a genome (RNA or DNA) that is encapsidated by a rigid protein shell. After delivery of the viral genome into the host cell, new capsid proteins, which are encoded by viral DNA or RNA, are expressed and self-assembled into new viral capsids. The main objective of my research was to study the key physical factors of genome ejection tha

Fragmentability, a foundational systems concept

Fragmentation is a fundamental process, beneath the level of logics. Fragmentation occurs in our most everyday activities. We analyse (literally, to break into fragments), describe, and interpret by performing fragmentations. We propose a linguistic concept of fragmentation, namely a complementaristic whole of "syntactic fragmentation" and "semantic fragmentation", as foundational for Systems and,
