In this study, I examine firstly the determinants of the wage earnings for immigrants from different countries, and secondly whether their wage earnings converge to those of comparable native-born Swedes. The study is based on a longitudinal dataset, and the data refers to 1991 and 1995, respectively. The empirical results indicate that immigrants in Sweden are heterogeneous, and different inco...

Physical and biogeochemical ocean dynamics can be intermittent and highly variable, and involve interactions on multiple scales. In general, the oceanic fields, processes and interactions that matter thus vary in time and space. For efficient forecasting, the structures and parameters of models must evolve and respond dynamically to new data injected into the executing prediction system. The co...

Perceptual indicators of multimedia quality have to be taken into account in order to build the truly end-toend communication architectures of the future. This paper investigates the perceptual impact of differing multimedia presentation frame rates on user information assimilation and level of satisfaction. We apply the Quality of Perception (QoP) concept, which encompasses not only a user’s a...

We investigate the impact of captions on deaf and hearing perception of multimedia video clips. We measure perception using a parameter called Quality of Perception (QoP), which encompasses not only a user's satisfaction with multimedia clips, but also his/her ability to perceive, synthesise and analyse the informational content of such presentations. By studying perceptual diversity, it is our...

The present study investigates Australian English (AusE) monolingual listeners’ perception of non-native vowels in Dutch, a language with fewer vowels compared to AusE. AusE listeners’ performance was compared to native monolingual Peruvian Spanish (PS) listeners whose L1 contains fewer vowels than Dutch. Results show that compared to PS listeners, AusE listeners were better at discriminating o...

Correct knowledge of soil moisture is important for improving the prediction of coupled land surface atmosphere interactions. This is due to the control that soil moisture exerts on the latent and sensible heat flux transfer between the land surface and atmosphere. Because of this strong dependence on moisture availability, improved atmospheric prediction requires correct initialisation of soil...

Disadvantages of Linguistic Origin: Evidence from Immigrant Literacy Scores This study quantifies the disadvantage in the formation of literacy skills of immigrants that arises from the linguistic distance between mother tongue and host country language. Combining unique cross-country data on literacy scores with information on the linguistic distance between languages, gaps in literacy test sc...
