Today a broad body of literature has emerged within the IS research community investigating the organizational consequences of IS implementations. However in view of these developments, it seems that practitioners are still faced with implementation problems, such as user dissatisfaction, resistance and mismatches between the new technology and existing work practices. It is this tension, within a
In this paper we study the distribution of the product of an inverse Wishart random matrix and a Gaussian random vector. We derive its asymptotic distribution as well as its approximate density function formula which is based on the Gaussian integral and the third order Taylor expansion. Furthermore, we compare obtained asymptotic and approximate density functions with the exact density which is o
Popular Abstract in English Airborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes. In order to understand completely the role of aerosols in atmosphere, their chemical composition is of basic importance. Chemical analysis of aerosols involves broadly two steps, extraction step and detection/quantification of chemical constituentsAirborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes.

Popular Abstract in Swedish Många av dagens biotekniska processer syftar till att framställa protein. Det är proteinets användningsområde som är avgörande för vilka renhetskrav som ställs på produkten. I vissa fall måste proteinet vara helt fritt från föroreningar för att inte åstadkomma oönskade effekter. Vaccinframställning är ett exempel på en sådan tillämpning. För andra ändamål, t ex vid framTwo polymers, alginate and Eudragit S-100 were used as reversibly soluble-insoluble ligand carriers for the selective isolation of enzymes and lectins respectively. These two polymers have the inherent property of being precipitated under well defined conditions. Alginate was made insoluble by the addition of Ca2+ ions, and Eudragit S-100 by a pH shift. The polymers were modified with affinity lig
The distinction between intrinsic and extrinsic value has given rise to a batch of fundamental questions concerning the very nature, importance and coherence of our core value concepts. Section I outlines an approach to the distinction between intrinsic and extrinsic value that has taxonomical advantages. Recent work has alerted us to the fact that the traditional way of explicating extrinsic valu
Facts are once again put to work in philosophical enterprises. The discussion in this paper is conducted under the presumption that we for this reason need to examine the nature of facts anew. To some extent it has been taken for granted that the question of properties and particulars is the primary problem to solve, and that the question of facts is secondary. This approach naturally leads to man

We study theoretically the linear conductance of a quantum dot connected to ferromagnetic leads. The dot level is split due to a noncollinear magnetic field or intrinsic magnetization. The system is studied in the noninteracting approximation, where an exact solution is given, and, furthermore, with Coulomb correlations in the weak tunneling limit. For the noninteracting case, we find an antireson
En fråga som dominerar den svenska välfärdspolitiska debatten är den höga ungdomsarbetslösheten. 1990-talets krisår framstår som en brytpunkt. Utbildningsperioderna har förlängts och etableringsfasen har blivit mer utdragen. Flera ungdomar lever i fattigdom, uppbär socialbidrag och fastnar i utanförskap. Till följd av förändringar i ett postindustriellt arbetsliv och i spåren av ny teknik i en til
Abstract in Finnish Inleding Dagen's biomedicinska utveckling bidrar till förbättrad livskvalitet för många människor. Det kan röra sig om nya läkemedel eller andra kliniska behandlingar med avgörande betydelse för en person's hälsotillstånd. Dessa medicinska möjligheter är emellertid inte helt oproblematiska. Ofta är stora ekonomiska kostnader förknippade, inte enbart med utvecklingsarbetet, men
Improving the quality of education is the goal of all pedagogical research. By using student surveys and course evaluations problem areas can be identified in most courses offered by universities. In this paper we perform a large-scale student survey in order to find the causes of, and remedies to, a widespread student dissonance in a mandatory course with over 100 students at Lund University. Our
Background. Dosimetry of the hypothalamus-pituitary (HP) region could allow prediction of the risk of growth hormone deficiency (GHD) following cranial irradiation. Procedure. Nineteen children (15 boys) with a median age of 6.3 years (range 1.7–16.5) at the time of irradiation of a brain tumor not involving the HP axis were followed for 1.2–6.3 years (median 3.4) from radiotherapy (RT). The dose
