Description
The purpose of this study was to investigate the impacts of visual cues and different types of self-explanation prompts on learning, cognitive load and intrinsic motivation, as well as the potential interaction between the two factors in a multimedia environment that was designed to deliver a computer-based lesson about the human cardiovascular system. A total of 126 college students were randomly assigned in equal numbers (N = 21) to one of the six experimental conditions in a 2 X 3 factorial design with visual cueing (visual cues vs. no cues) and type of self-explanation prompts (prediction prompts vs. reflection prompts vs. no prompts) as the between-subjects factors. They completed a pretest, subjective cognitive load questions, intrinsic motivation questions, and a posttest during the course of the experience. A subsample (49 out of 126) of the participants' eye movements were tracked by an eye tracker. The results revealed that (a) participants presented with visually cued animations had significantly higher learning outcome scores than their peers who viewed uncued animations; and (b) cognitive load and intrinsic motivation had different impacts on learning in multimedia due to the moderation effect of visual cueing. There were no other significant findings in terms of learning outcomes, cognitive load, intrinsic motivation, and eye movements. Limitations, implications and future directions are discussed within the framework of cognitive load theory, cognitive theory of multimedia learning and cognitive-affective theory of learning with media.

Description
A statement appearing in social media provides a very significant challenge for determining the provenance of the statement. Provenance describes the origin, custody, and ownership of something. Most statements appearing in social media are not published with corresponding provenance data. However, the same characteristics that make the social media environment challenging, including the massive amounts of data available, large numbers of users, and a highly dynamic environment, provide unique and untapped opportunities for solving the provenance problem for social media. Current approaches for tracking provenance data do not scale for online social media and consequently there is a gap in provenance methodologies and technologies providing exciting research opportunities. The guiding vision is the use of social media information itself to realize a useful amount of provenance data for information in social media. This departs from traditional approaches for data provenance which rely on a central store of provenance information. The contemporary online social media environment is an enormous and constantly updated "central store" that can be mined for provenance information that is not readily made available to the average social media user. This research introduces an approach and builds a foundation aimed at realizing a provenance data capability for social media users that is not accessible today.

Description
This dissertation is both creative and scholarly, engaging in the technique of "narrative scholarship," an increasingly accepted technique within the field of ecocriticism. The project is framed by my experiences with Spanish and Latino actors as well as activists involved with the 15-M movement in and around Madrid. It takes a "material ecocritical" approach, which is to say that it treats minds, spirits and language as necessarily "bodied" entities, and creates an absolute union between beings and the matter that constructs them as well as their habitat. I apply the lens of Jesper Hoffmeyer's Biosemiotics, which claims that life is at its most essential levels a communicative process. In other words, I will explore how "all matter is 'storied' matter," as well as how the "semiosphere," which is an important concept in biosmiotics, signaling a semiotic environment that predicts and defines all biological bodies/life, the human, the plant and the animal as beings who are made of and involved in semiotic activity, can serve as a basis for union amongst all bodies and provide a model of cooperation rooted in "storytelling." My project aims to embody what Wendy Wheeler describes as ecocriticism's, "syntheses between the sciences and the humanities" It is my strong opinion that creative writing has the power to offer the general public insight into the reasons why new research in biosemiotics is so important to the work that activists are doing to raise awareness of how humans can live responsibly on the only planet that is our home. This will help readers of creative writing and cultural studies scholars understand why they ought to embrace science, especially in literary and cultural studies, as a path to better understanding of the role of the humanities in an increasingly scientifically oriented world.
