  1. 1. Fertility, childcare and labour market : dynamics in time and space

    Author : Elena Kotyrlo; Magnus Wikström; Niklas Hanes; Giovanni Forchini; Anders Stenberg; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; nationalekonomi;

    Abstract : Paper [I] focuses on the effects of time and space dynamics on the description offertility in Sweden. Fertility is an important determinant of long-term populationgrowth and labour market conditions. The influence of time dynamics inpostponing or accelerating childbearing is assessed by considering two differenteffects of earnings. READ MORE

  2. 2. Freshwater methane and carbon dioxide fluxes : Spatio-temporal variability and an integrated assessment of lake and stream emissions in a catchment

    Author : Sivakiruthika Natchimuthu; David Bastviken; Åsa Danielsson; Peter A. Raymond; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Lakes; streams; spatio-temporal variability; CH4 flux; CO2 flux; gas transfer velocity; Sjöar; vattendrag; rumsliga och tidsmässiga variationer; CH4-flöden; CO2-flöden; gasutbyteshastighet;

    Abstract : Freshwater bodies such as lakes and streams release the greenhouse gases methane (CH4) and carbon dioxide (CO2) into the atmosphere. Global freshwater CH4 and CO2 emissions have been estimated to be of a similar magnitude to the global land or ocean carbon sink, and are thus significant components of global carbon budgets.

    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Data uncertainty; Discharge; Disinformative data; Evaporation; Flow-duration curve; Global hydrology; Neural networks; Numerical weather prediction; Precipitation; Quality control; Regionalisation; Ungauged basins; Water balance; Avdunstning; avrinningsområden utan vattenföringsdata; dataosäkerhet; desinformativa data; global hydrologi; kvalitetskontroll; nederbörd; neurala nät; numerisk vädermodell; regionalisering; varaktighetskurva; vattenbalans; vattenföring; Hydrology; Hydrologi;

    Abstract : Water is essential for human well-being and healthy ecosystems, but population growth and changes in climate and land-use are putting increased stress on water resources in many regions. To ensure water security, knowledge about the spatiotemporal distribution of these resources is of great importance. READ MORE

  4. 4. Marine Current Resource Assessment : Measurements and Characterization

    Author : Nicole Carpman; Karin Thomas; Mats Leijon; Sandra Eriksson; Mairead Atcheson; Uppsala universitet; []

    Abstract : The increasing interest in converting energy from renewable resources into electricity has led to an increase in research covering the field of marine current energy, mainly concerning tidal currents and in-stream tidal turbines. Tides have the advantage of being predictable decades ahead. READ MORE

  5. 5. Making travel sustainable with ICT? : The social practice of travel planning and travel information use in everyday life

    Abstract : Adopting the perspective of the traveller, this thesis examines how travel plans are actually made in the everyday situation and how information is used and drawn on when planning the many, often unremarkable, trips of ordinary urban life. Ethnographical field studies in southern Stockholm, Sweden, employing a practice theory perspective showed that people use a vast mixture of different types of information when planning and making trips.
