Hamilton´s rule is considered a cornerstone in evolutionary biology. It is used to understand why organisms help relatives and serves as starting point for the development of cooperation between strangers. The rule is based on a method from economics. It compares a benefit to cost ratio (k) to...

Help within genetically related and unrelated organisms as well as investments of investors holding shares to different degree including charity can be understood within the ensemble concept. In an ensemble transfer of substrate from a source to a sink may result in superadditivity as well as...

The active and independent ensemble is redistributing substrate from source to sink, controlling internal giving and taking by its own. This will lead to superadditivity in comparison to the inactive ensemble. The surface area of superadditivity differs from dependent ensembles. The line of...

Within the transfer space source and sink exchange substrates (material and energy) to selfishly optimize their own productivity. Under certain conditions this will lead to a productivity increase of the whole ensemble. The present day view that cooperation is the most productive interaction...

The explanation of heterogeneity when combining different studies is an important issue in meta analysis. Besides including a heterogeneity parameter in the analysis, it is also important to understand the possible causes of heterogeneity. A possibility is to incorporate study-specific...
