    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; impact analysis; roles; organisational levels; requirements engineering; imputation;

    Abstract : Change is unavoidable in software development. During the entire lifecycle of a product, from concept to retirement, the environment changes; the needs of customers or the market change and grow, and with them the requirements on the system being developed. READ MORE

  2. 2. Geochronology of impact structures - constraining syn- and post-impact processes using the 40Ar/39Ar and U-Pb techniques

    Author : Maria Herrmann; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Impact structure; Dating impact events; 40Ar 39Ar dating; U-Pb dating; Siljan impact structure; Mien impact structure; Hummeln impact structure; Puchezh-Katunki impact structure;

    Abstract : The discovery, at the beginning of the 20th century, that elements can transform into other elements, due to the spontaneous decay of an instable to a stable atomic nuclei, gave rise to a powerful source for age information in many fields of earth science. For impact structures, it is crucial to establish well-defined and precise ages in order to understand how impact events affect the Earth’s geo and biosphere and also with regard to possible future events that can have devastating effects on our civilization.

  3. 3. Urban drainage and climate change : impact assessment

    Author : Karolina Berggren; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : According to the Intergovernmental Panel on Climate Change (IPCC, 2007), the global mean temperature has increased by 0,7 °C during the last 100 years and, as a consequence, the hydrological cycle has intensified with, for example, more intense rainfall events. As urban drainage systems have been developed over a long period of time and design criteria are based upon climatic characteristics, these changes will affect the systems and the city accordingly.

  4. 4. Addressing poor educational outcomes among children with out-of-home care experience : Studies on impact, pathways, and interventions

    Author : Hilma Forsman; Lars Brännström; Bo Vinnerljung; Marie Sallnäs; Mattias Strandh; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; child welfare; out-of-home care; educational outcomes; impact; pathways; interventions; longitudinal; evaluation; socialt arbete; Social Work;

    Abstract : Children with out-of-home care (OHC; foster family/residential care) experience is a high-risk group for future adverse outcomes. With an ambition of supporting the design of effective preventive child welfare measures targeting children in OHC, the overall aim of this thesis is to examine education as a possible intervention path for improving their development and overall life chances.
