Click Here Now: The Impact of Color and Size on Advertisements

Businesses and companies are always trying to find the most effective way to advertise their products to create higher click-through rates, increasing the intent to purchase, and consequently raising sales and revenue. This research examines the effect that several different design elements of an online advertisement have on the attitudes or behaviors of consumers. An online survey was sent out to students at Gettysburg College, consisting of pairs of advertisements differing either in color, hue, or size. Participants in the online survey were asked to click on the image that they preferred. All three of these categories had a significant effect on click-through rates on advertisements. Highly-saturated advertisements were significantly preferred over the low-saturated advertisements. There was a significant difference in size preference, but the average preference was evenly split between square and vertical rectangle sizes in the shape category. Warm colors were marginally preferred over cool colors in the images that were used. These findings are important for businesses in order for them to receive the greatest number of clicks on products advertised because those clicks lead to purchases of the product. Further research could also include the examination of other characteristics of advertisements

Correlations of three-dimensional motion of chromosomal loci in yeast revealed by the double-helix point spread function microscope

Single-particle tracking has been applied to study chromatin motion in live cells, revealing a wealth of dynamical behavior of the genomic material once believed to be relatively static throughout most of the cell cycle. Here we used the dual-color three-dimensional (3D) double-helix point spread function microscope to study the correlations of movement between two fluorescently labeled gene loci on either the same or different budding yeast chromosomes. We performed fast (10 Hz) 3D tracking of the two copies of the GAL locus in diploid cells in both activating and repressive conditions. As controls, we tracked pairs of loci along the same chromosome at various separations, as well as transcriptionally orthogonal genes on different chromosomes. We found that under repressive conditions, the GAL loci exhibited significantly higher velocity cross-correlations than they did under activating conditions. This relative increase has potentially important biological implications, as it might suggest coupling via shared silencing factors or association with decoupled machinery upon activation. We also found that on the time scale studied (∼0.1–30 s), the loci moved with significantly higher subdiffusive mean square displacement exponents than previously reported, which has implications for the application of polymer theory to chromatin motion in eukaryotes
