      Di Nunno, Giulia; Haferkorn, Hannes Hagen (Journal article; Peer reviewed, 2017)
      Time change is a powerful technique for generating noises and providing flexible models. In the framework of time changed Brownian and Poisson random measures we study the existence and uniqueness of a solution to a ...
    • An analysis of maintenance schedules for public facilities 

      Hopland, Arnt Ove; Kvamsdal, Sturla F; Sandal, Leif Kristoffer (Journal article; Peer reviewed, 2019)

    • An Analysis of Social Seed Network and Its Contribution to On-Farm Conservation of Crop Genetic Diversity in Nepal 

      Poudel, Diwakar; Sthapit, Bhuwon; Sherstha, Pratap (Journal article; Peer reviewed, 2015)
      Social seed systems are important for the maintenance of crop genetic diversity on farm. This is governed by local and informal system in the community through a farmers’ network. This paper analyses these local seed ...
    • An Educational Game in Collaborative Logistics 

      D'Amours, Sophie; Rönnqvist, Mikael (Journal article; Peer reviewed, 2013)
      We describe an educational game in collaborative logistics. The game is based on an award-winning application in cost allocation in transportation. The purpose of the game is to acquire an understanding of negotiation, ...
    • An experimental study of prosocial motivation among criminals 

      Cappelen, Alexander Wright; Sørensen, Erik Øiolf; Tungodden, Bertil; Birkeland, Sigbjørn (Journal article; Peer reviewed, 2014)
      The fact that criminal behavior typically has negative consequences for others provides a compelling reason to think that criminals lack prosocial motivation. This paper reports the results from two dictator game experiments ...
    • Are AIS-based trade volume estimates reliable? The case of crude oil exports 

      Ådland, Roar Os; Jia, Haiying; Strandenes, Siri Pettersen (Peer reviewed; Journal article, 2017)
      Most global trade statistics in the public domain refer to official customs data, which are not generally available on a micro (individual cargo) level. With the increasing availability and completeness of ship positioning ...
