Enkelt uttryckt är Samverkansinlärning (SI) en studiecirkel kopplat till en utmanande kurs. SI leds av en senior student som utformar läraktiviteter där studenterna arbetar i grupper med att förklara och förtydliga svårt kursmaterial. Målsättningen med SI, förutom förbättrade prestationer i den aktuella kursen, är att studenterna skall utveckla goda studiestrategier och bli mer självständiga i sit
When you think of fungi, you’ll probably picture a huddle of chubby brown mushrooms, or the large, red-capped toadstools you stumble across in the woods. In doing so, you’re reducing fungi to their reproductive organs – tasty or striking as they may often be.
Sex chromosomes were discovered more than 100 years ago. They have been studied intensely from a theoretical perspective since then, giving rise to a large body of testable predictions about their evolution from autosomes. A common feature of sex chromosomes is recombination suppression between the sex chromosome copies (X and Y in male heterogametic systems, or Z and W in female heterogametic sys
Vad innebär värden och ideal som exempelvis jämlikhet, trygghet och personlig autonomi i migrationspolitiska frågor? Bör välfärdsstaten och jämlikheten inom landet prioriteras, vilket skulle motivera en mer restriktiv migrationspolitik? Eller bör global utjämning av individers säkerhet och livskvalitet prioriteras genom en öppnare migration? Politiker och engagerade medborgare har nytta av att bek
A variable gain transimpedance amplifier (TIA) is presented featuring single-ended to differential conversion by means of negative feedback. The proposed topology also ensures stability when amplifier gain is varied. Furthermore, effective input capacitance of the TIA is reduced by using a positive capacitive feedback. The circuit is intended for intermediate frequency (IF) over fiber systems, but
Selecting requirements for a release of software is a difficult undertaking as people have trouble comparing requirements of different types and have natural biases towards short-terms gains over longer-term sustainability. Portfolio theory is proposed as a solution to this problem, as it provides a method for balancing investment options to maximize the likelihood of a given return. This approach
