BACKGROUND Packed lunch is the dominant lunch format in many countries including Denmark. School lunch is consumed unsupervised, and self-reported recalls are appropriate in the school setting. However, little is known about the accuracy of recalls in relation to packed lunch. OBJECTIVE To assess the qualitative recall accuracy of self-reported consumption of packed lunch among Danish 11-year...

King and Korf [9] introduced, in the framework of a discrete-time dynamic market model on a general probability space, a new concept of arbitrage called free lunch in the limit which is slightly weaker than the common free lunch. The definition was motivated by the attempt at proposing the pricing theory based on the theory of conjugate duality in optimization. We show that this concept of arbi...

Modeling human behavior is a complex task, as it might include unpredictability, sub-conscious knowledge and intuition. This paper presents some initial results from a novel algorithm that creates human behavior models automatically by observing humans performing. Furthermore, the paper uses conclusions from the No Free Lunch Theorems to signify the scalability of the modeling algorithm. These ...

We provide equivalence of numerous no-free-lunch type conditions for financial markets where the asset prices are modeled as exponential Lévy processes, under possible convex constraints in the use of investment strategies. The general message is the following: if any kind of free lunch exists in these models it has to be of the most egregious type, generating an increasing wealth. Furthermore,...
