In this article, we present results of an empirical study with 500 German students of grades 7 and 8. The study focussed on students’ mathematics achievement and their interest in mathematics as well as on the relation between these two constructs. In particular, the results show that the development of an individual student’s achievement between grade 7 and grade 8 depends on the achievement l...

With low temperature long time (LTLT) cooking it can take hours for meat to reach a final core temperature above 53°C and germination followed by growth of Clostridium perfringens is a concern. Available and new growth data in meats including 154 lag times (tlag), 224 maximum specific growth rates (μmax) and 25 maximum population densities (Nmax) were used to developed a model to predict growth...

Belief disagreements have been suggested as a major contributing factor to the recent subprime mortgage crisis. This paper theoretically evaluates this hypothesis. I assume that optimists have limited wealth and take on leverage in order to take positions in line with their beliefs. To have a signi…cant e¤ect on asset prices, they need to borrow from traders with pessimistic beliefs using loans...

The phase behavior of dimerizing ~associating! rigid particles is studied by both theory and computer simulation. The model molecule comprises a hard spherocylinder of length L and diameter D with a terminal square well bonding site embedded in one of the hemispherical caps. This model mimics the properties of simple hydrogen bonding mesogens; for example, mesogens with a carboxylic acid end gr...

a r t i c l e i n f o JEL classification: C15 G14 D53 D82 Keywords: Information costs Noise trader Fundamental analysis Agent-based modeling This study explores the long-standing question about the survival of noise traders in financial markets through the relatively new method of agent-based modeling. We find that, in the normal case, there are two attractors for the ratio of experts versus no...

C an rural financial inclusion enhance agricultural growth? This study, using annual data over the period 1981-2014 and the ARDL bounds testing approach, captures the long run as well as the short-run dynamics of the relationship between financial inclusion and agriculture in Nigeria. The results show that usage of financial services has significant impacts on agriculture both in the...

A model is developed where firms in a financial system have to settle their debts to each other by using a liquid asset (or money). The question that is studied is how many firms must have access to this asset from outside the financial system to make sure that all debts within the system are settled. The main result is that these liquidity needs are larger when these firms are more interconnec...
