Í þessari grein er fjallað um lýðfræði sem undirgrein félagsfræðinnar í alþjóðlegu vísindastarfi. Fjallað er um helstu svið innan lýðfræðinnar, breytingar á mannfjölda á Íslandi síðustu áratugi og rannsóknir sem íslenskir fræðimenn hafa gert til aukins ...

This paper argues that philosophical practice in the Western world, in particular analytic philosophy, suffers from problems that contribute to its lack of diversity in two senses: the exclusion of women and minorities, and a narrow choice of subjects ...

Previous studies have shown an increased risk for mental health problems in children born to both younger and older parents compared to children of average-aged parents. We previously used a novel design to reveal a latent mechanism of genetic association ...

Background Self-report questionnaires are commonly used in epidemiology, but may be susceptible to misclassification, especially if answers are given on behalf of others, e.g. children or parents. The aim was to determine agreement and analyse predictors ...

Manuscript culture in Icelandic immigrant communities in North America is examined through the case study of an immigrant-scribe, Albert Jóhannesson (1847–1921), who left Iceland as an adult in 1884 and eventually settled in the community of Hecla ...

Using a sub-millimeter exciton-polariton waveguide suitable for integrated photonics, we experimentally demonstrate nonlinear modulation of pico-Joule pulses at the same time as amplification sufficient to compensate the system losses. By comparison ...
