1. 1. Factors Influencing Drivers' Speeding Behaviour

   Författare :Henriette Wallén Warner; Lars Åberg; J. A. Rothengatter; Uppsala universitet; []
   Nyckelord :Psychology; theory of planned behaviour; driver behaviour questionnaire; intelligent speed adaptation; observed speeding; beliefs; attitudes; Psykologi;

   Sammanfattning : Every year many people all over the world are killed and severely injured in road traffic accidents. Even though driving too fast is a behaviour well known to contribute to both the number and the outcome of these accidents, drivers are still speeding. LÄS MER

3. 2. Speed Choice : The Driver, the Road and Speed Limits

   Författare :Mats Haglund; Nils Petter Gregersen; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Driving behaviour; Speed choice; Risk estimates; Enforcement; Attitudes; Psykologi; Psychology; Psykologi; Psychology; psykologi;

   Sammanfattning : Speed choice is one of the more characteristic features of driver behaviour. The speed a driver chooses to travel at determines the degree of difficulty he or she operates under. Higher speeds lead to more accidents, higher accident risk and more severe consequences of an accident. LÄS MER

4. 3. Interpreting budget deficits and productivity fluctuations

   Författare :Jyry Hokkanen; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

   Sammanfattning : This thesis includes four self-contained essays on budget deficits and productivity fluctuations:ESSAY I evaluates the effects of budget deficits on several key macroeconomic variables of the Swedish economy by estimating a vector autoregression model. The main finding is that - apart from a positive transitory real interest rate effect associated with a shock in the deficit - neither actual nor unexpected movements in deficits have any significant explanatory power for the determination of real non-fiscal variables.

5. 4. Time and inequality - A study of individual preferences

   Författare :Hjördis Hardardottir; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Behavioral economics; Experimental economics; Individual preferences; Time preferences; Social preferences; income inequality; Health inequality;

   Sammanfattning : This thesis consists of three papers that study individual preferences. The focus of the first two papers is on time preferences. In the third paper, preferences regarding how inequality in health and income should be defined are elicited. LÄS MER

7. 5. Multi-Photon Interactions with a Time Structure

   Författare :Alexander Baev; KTH; []
   Nyckelord :nonlinear optics; two-photon absorption; mirrorless lasing; charge-transfer chromophores; solutions; resonant photoemission; life-time vibrational interference; scattering duration time; electron Doppler effect; polymers;

   Sammanfattning : The present thesis concerns aspects of the interaction ofmatter in gas, liquid and solid phases, with electromagneticradiation, ranging from the optical to the X-ray region. Overthe last decade the availability of ultrashort strong laserpulses as well as of high power synchrotron sources of tunableX-ray radiation has stimulated a rapid development of newexperimental techniques which makes it possible to analysedifferent physical, chemical and biological processes inunprecedented detail.
