Some authors suggest that many of the icons used in evolutionary diagrams cones of increasing diversity (i.e., trees with narrow bases and wide tops), upwardly directed trees, and trees with differential resolution (emphasizing some taxonomic groups)—reinforce ideas of evolution as progressive and directional (Gould 1995, 1997; O'Hara 1992).
For example, evolution is often viewed as progressive and directional.
Figure 3B shows a DNAm heatmap for all DMRs, displaying progressive and directional DNAm change at several regions in the Young, Mid, and Old samples.
Also a progressive and directional variation can be observed among groups by Barthel Index and SF-12 PCS scores, with those scoring the lowest on these tests having the lowest Lawton IADL scores.
This apparent sequence-independent, progressive and directional enrichment along the Xist/ Tsix region indicates that, in the absence of Tsix transcription, the hotspot of H3K27me3 spreads into the Xist/ Tsix locus and, therefore, suggests that Tsix acts as a boundary element partitioning two distinct chromatin domains.
"History is directional and progressive, and the modernization process points to liberal democracy as its fullest embodiment.
How visitors perceive exhibits with humans and other living or extinct primates in them is complex and challenging, but they are often interpreted as being linear, directional, and progressive (Scott 2007, 2010; Scott and Giusti 2006).
These results from the psychological literature are consistent with findings from museum studies that visitors typically interpret exhibits on human evolution as depicting the evolution of our species as linear, directional, and progressive (Scott [2007], [2010]).
What significance, if any, visitors might attribute to these particular examples is unknown, but previous work has demonstrated the potential for interpreting the layout of exhibits that include humans, their most recent extinct relatives, and/or other primates as directional and progressive (Scott and Giusti 2006).
The theory was further adapted and extended to the prediction of in situ first ply yielding and failure (FPY and FPF) and progressive failure of multi-directional laminates under static and dynamic loadings.
