Enhancing policy delivery: normalizing four critical contributions

Four Contributions to Experimental Economics

Maternal contributions to preterm delivery.

Preterm delivery (PTD) is a complex trait with a significant familial component. However, no specific inheritance patterns have been established. The authors examined the contribution of PTDs in both the woman's family and her partner's family to her risk of PTD. The authors linked birth information from Danish national registers with pedigree information from the Danish Family Relations Databa...

enhancing critical thinking with literary discussion

the major aim of this study was to investigate the effect of literary discussion on critical thinking. to this end, two classes (experimental and control groups) were selected from college of ferdowsi university. in both groups literature was used as supplementary homework. students were supposed to read short stories and poems at home and present them in class. the students in the experimental...

Four Canadian Contributions to Stochastic Modeling

We outline the history, significance, and impact of four important contributions by Canadian researchers to stochastic modeling for operational research: the use of the uniformization method to compute transient probabilities for Markov chains, pioneered by Winfried K. Grassmann, contributions to Markov decision processes by Martin L. Puterman, contributions to the development of random number ...

Factorization of Twist-Four Gluon Operator Contributions

We consider diagrams with up to four t-channel gluons in order to specify gluonic twist-four contributions to deep inelastic structure functions. This enables us to extend the method developed by R.K.Ellis, W.Furmanski, and R. Petronzio (EFP) [1] to the gluonic case. The method is based on low-order Feynman diagrams in combination with a dimensional analysis. It results in explicitly gauge inva...
