1. Upconversion in Er doped silica : - characterization and modeling
Sammanfattning : Further increase of erbium concentrations in Er-doped amplifiers and lasers is needed for the design of efficient, reliable, compact and cost-effective components for telecommunications and other photonic applications. However, this is hindered by Er concentration dependent loss mechanism known as upconversion. LÄS MER
2. Perspectives from a human-centred archaeology : Iron Age people and society on Öland
Sammanfattning : The objective of this study was to develop, test and evaluate a specifically defined interdisciplinary approach—the human-centred approach—as applied to a case study, Iron Age Öland. Four themes were selected to highlight different aspects of particular interest in Öland: taphonomy, diet, migration, and social organization. LÄS MER
3. Free to Choose? : Studies of Opportunity Constraints and the Dynamics of School Segregation
Sammanfattning : As a result of the negative consequences and persistence of school segregation, its causes have received a great deal of scholarly attention across a range of disciplines. However, the existing research has tended to overlook those aspects of the segregation process that lie beyond the choice of the individual. LÄS MER
