  1. 1. Speciation - What Can be Learned from a Flycatcher Hybrid Zone?

    Författare :Chris Wiley; Anna Qvarnström; Lars Gustafsson; Roger Butlin; Uppsala universitet; []
    Nyckelord :Biology; speciation; reinforcement; fitness; postzygotic isolation; asymmetrical hybridization; hybrid zone; species recognition; mate choice; sexual selection; direct benefits; parasite resistance; delayed plumage maturation; Ficedula hypoleuca; Ficedula albicollis; flycatcher; Biologi;

    Sammanfattning : Studies of hybrid zones offer important insights into the process of speciation. Much of the knowledge to be gained is dependent on an accurate estimation of the strength of pre- and post-zygotic isolation between hybridizing taxa. My results demonstrate that hybridization can variously affect different components of fitness. LÄS MER

  2. 2. Beyond scattering – what more can be learned from pulsed keV ion beams?

    Författare :Svenja Lohmann; Daniel Primetzhofer; Andreas Wucher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Charge exchange; Deep UV photons; Electron emission; Silicon; Sputtering; TOF-MEIS; Fysik; Physics;

    Sammanfattning : Interactions of energetic ions with matter govern processes as diverse as the influence of solar wind, hadron therapy for cancer treatment and plasma-wall interactions in fusion devices, and are used for controlled manipulation of materials properties as well as analytical methods. The scattering of ions from target nuclei and electrons does not only lead to energy deposition, but can induce the emission of different secondary particles including electrons, photons, sputtered target ions and neutrals as well as nuclear reaction products.

  3. 3. What is taught and what is learned. Professional insights gained and shared by teachers of mathematics

    Författare :Angelika Kullberg; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; learning study; variation theory; teaching; learning; mathematics education; negative numbers; rational numbers;

    Sammanfattning : The aim of the thesis is to contribute to knowledge about relationships between teaching and learning in school. The framework used in this research, variation theory, states that, to improve student learning, attention must be paid to what is being learned, the capability that is to be improved and the features (critical features) that it is necessary for the learner to discern.

  4. 4. Hydrology and forests in the Blue Nile basin : what can be learned from half a century of observations and community perception for water management?

    Författare :Solomon Gebrehiwot; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Forest cover change is considered a major cause of water scarcity during the dry season in the Blue Nile River Basin of Ethiopia, which is part of the Nile River system. However, this is an over-simplification of the complex reality of forest and flow relationships, especially in the tropics. LÄS MER

  5. 5. Improving incident reports in the swedish armed forces

    Författare :Ulrica Pettersson; Försvarshögskolan; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Incident reports; lessons learned; design science; memory psychology; cued recall; eyewitness testimony; Ledningsvetenskap; Ledningsvetenskap; Incident reports; lessons learned; design science; memory psychology; cued recall; eyewitness testimony;

    Sammanfattning : It is generally maintained that learning should be a part of the daily routines of many organizations; this is often referred to as lesson learned processes. The purpose of organizational learning is to foster improvements that seek to both reduce incidents and accidents and reduce their consequences when they nevertheless happen. LÄS MER
