Improving Environmental Protection: One Imagined Touch At A Time, Luke Ingalls Liska

USF Tampa Graduate Theses and Dissertations

Can imagined touch of flora and fauna (i.e., the plants and animals of the natural world) make you more willing to support environmental protection efforts? Across seven studies, I demonstrate that by asking consumers to imagine touching fauna, marketers can encourage consumers to become more engaged in environmental protection efforts. This effect occurs because imagined touch generates haptic imagery, which enhances a consumer’s emotional attachment to fauna. I demonstrate that emotional attachment to fauna induced via imagined touch enhances individual’s willingness to share Facebook posts, improves their willingness to support increased fines for environment-related offenses, and increases the number of …

Detecting Digitally Forged Faces In Online Videos, Neilesh Sambhu

USF Tampa Graduate Theses and Dissertations

We use Rossler’s FaceForensics dataset of 1004 online videos and their corresponding forged counterparts [1] to investigate the ability to distinguish digitally forged facial images from original images automatically with deep learning. The proposed convolutional neural network is much smaller than the current state-of-the-art solutions. Nevertheless, the network maintains a high level of accuracy (99.6%), all while using the entire FaceForensics dataset and not including any temporal information. We implement majority voting and show the impact on accuracy (99.67%), where only 1 video of 300 is misclassified. We examine why the model misclassified this one video. In terms of tuning …
