Despite the rapid adoption of Facebook as a means of photo sharing, minimal research has been conducted to understand user gratification behind this activity. In order to address this gap, the current study examines users’ gratifications in sharing photos on Facebook by applying Uses and Gratification (U&G) theory. An online survey completed by 368 respondents identified six different gratifica...

In this supplementary material, we provide further details for each of our Amazon Mechanical Turk (MTurk) tasks, and on our implementation. The data from all of our experiments is fully open and available on-line at http://opensurfaces.cs.cornell.edu/. Statistics about the experiments and the results are also hosted online, and they will be continually updated as the database grows. Task descri...

The size of grains in gravel and conglomerate deposits is most easily measured on photos taken from related outcrops. However, the occlusion by sedimentary matrix or other grains, possible distortions photos, could introduce a bias such datasets. Here, we explore uncertainties associated with datasets where lengths were photos. To this end, analysed coarse-grained (>2 mm) fluvial material pit (...

We present a discussion of the precision for the PHOTOS Monte Carlo algorithm, with improved implementation of QED interference and multiple-photon radiation. The main application of PHOTOS is the generation of QED radiative corrections in decays of any resonances, simulated by a “host” Monte Carlo generator. By careful comparisons automated with the help of the MC-TESTER tool specially tailore...

Near-duplicate detection techniques are exploited to facilitate representative photo selection and region-of-interest (ROI) determination, which are important functionalities for efficient photo management and browsing. To make near-duplicate detection module resist to noisy features, three filtering approaches, i.e., point-based, region-based, and probabilistic latent semantic (pLSA), are deve...

We tested a prediction that females' duration estimates of briefly-viewed male, but not female, photos would be modulated by attractiveness. Twenty-seven female participants viewed sequences of five stimuli of identical duration in which the first four were sine-wave gratings (Gabor discs) and the fifth was either the same sine-wave grating (control trials) or a photo of an attractive or unattr...

Erratum Upon publication of the original article [1], the incorrect figure was included as Fig. 8. Additionally, the following paragraph found in Results, under the subheading; Weekend clubs: social mediainstagram “The number of photos acquired was 937 in total, but the top 3 contributors (1 girl and 2 boys) uploaded 70% of the photos, as shown in Fig. 8” should read “ The number of photos acqu...

Attractive people are considered by others to have many positive qualities and in the case of social skills and intelligence, these attributions are often true. In internet dating, individuals with attractive profile photos are viewed more favorably overall, but no research has yet established whether they indeed have more positive qualities. We addressed this issue by having 50 women independe...
