The DIFs are a family of secreted chlorinated molecules that control cell fate during development of Dictyostelium cells in culture and probably during normal development too. They induce stalk cell differentiation and suppress spore cell formation. The biosynthetic and inactivation pathways of DIF-1 (the major bioactivity) have been worked out.

Most computerized data is not under the purview of traditional database management systems, but, rather, it is stored in files. Data Interchange Formats (DIFs) are the basis of an important class of such files, containing massive volumes of data, and serving a large user community.

Not all DIF is shaped similarly
Psychometrika, 2021In response to the target article by Teresi et al. (2021), we explain why the article is useful and we also present a different approach. An alternative category of differential item functioning (DIF) is presented with a corresponding way of modeling DIF, based on random person and random item effects and explanatory covariates.

Broadband development and firm creation: Dif-in-dif estimates for Germany
AHFE International, 2022Although some of the outcomes of the digital transformation are reflected in the scientific literature, the connection between high-speed internet transmission rates and firm entries is still poorly studied. While some positive impact of basic broadband availability in Germany was found in our previous studies, in this paper we decided to examine the ...

Practitioners are increasingly becoming interested in Differential Item Functioning (DIF) forimproving the validity of test and scale interpretations. Among the statistical procedures availableto assess DIF in dichotomous and polytomous items, the Mantel-Haenszel chi-square (1959) andother standardization proceduresmay beparticularly attractive to ...
