Description
Website usage on both smartphone and tablet devices is rapidly increasing. Website success hinges largely upon how well information on the site is recalled and perceived. The purpose of this study is to explore the question of whether or not the differences in display size and resolution of smartphone versus tablet devices affect the recall of website information. I hypothesize that tablets will produce greater website recall than smartphones, due to their larger screen size and higher resolution which may reduce cognitive strain. During the study, participants viewed a sample website for two minutes on either an iPhone or iPad, and then participated in a brief 20 question memory test to evaluate how well they remembered the website information. Although test scores for the iPad users were about one test point higher than test scores for the iPhone users, the difference was not statistically significant. However, the study was limited by the low sample size (n = 94). This indicates that further research may find that tablets indeed allow for increased recall of certain kinds of website content.

Description
The marmoset monkey (Callithrix jacchus) is a new-world primate species native to South America rainforests. Because they rely on vocal communication to navigate and survive, marmosets have evolved as a promising primate model to study vocal production, perception, cognition, and social interactions. The purpose of this project is to provide an initial assessment on the vocal repertoire of a marmoset colony raised at Arizona State University and call types they use in different social conditions. The vocal production of a colony of 16 marmoset monkeys was recorded in 3 different conditions with three repeats of each condition. The positive condition involves a caretaker distributing food, the negative condition involves an experimenter taking a marmoset out of his cage to a different room, and the control condition is the normal state of the colony with no human interference. A total of 5396 samples of calls were collected during a total of 256 minutes of audio recordings. Call types were analyzed in semi-automated computer programs developed in the Laboratory of Auditory Computation and Neurophysiology. A total of 5 major call types were identified and their variants in different social conditions were analyzed. The results showed that the total number of calls and the type of calls made differed in the three social conditions, suggesting that monkey vocalization signals and depends on the social context.

Description
Gift-giving economies are economic models that freely give resources rather than barter for them or purchase them from market. Need-based transfers fit into this economic model by freely giving resources on the basis of need, provided the giver can spare the resources. The Maasai are an East African pastoral tribe that practices need-based transfers through a tradition they call osotua. If they have a partner with an established osotua relationship, then they will give any amount of cattle that partner request, provided they can spare the cattle. Cheating each other is unheard of in this tradition, but for this simulation I am introducing cheating into this economic model through feigning need. If a cheater is not in need, they will act like they are in need. If they are in need, then the cheater will request more cattle than what they need to survive. I am testing two different responses to cheating: walking-away and punishing. In the walk-away condition, the victim ends their osotua partnership and establishes a new one. In the punishment condition, a portion of the cheater's stolen cattle is destroyed.

Description
Perceptions of the self differ between cultures, generally between those cultures in the West and East. Some of the ways that these individuals from these cultures may differ are in their self-construal, their collectivist and individualist tendencies, and how they perceive control in their lives. The current study proposes that some of these differences are influenced by different concepts individuals hold regarding the "soul", or inner self. These concepts may be promoted by the different religious beliefs prominent in different regions. The Soul Perception Index, being developed through this study, measures belief in multiple souls, a universal soul, a single soul, or no soul. It was predicted that a belief in a single soul will correlate with an individual view of the self (individualism, independent self-construal, internal locus of control), and a universal or multi-soul belief will correlate with an interdependent view of the self (collectivism, interdependent self-construal, and external locus of control). We found that these variables did not significantly differ in their relationships with soul belief. However, Indian Hindu participants and Chinese participants seemed to score highly on all self-view variables and all soul perception types indicating that individuals from these cultures may be more predisposed to hold opposing beliefs simultaneously while US Christians are not.

Description
This research examined the influence that Christian and Hindu religious beliefs have on environmentalism; specifically, whether beliefs that one would return to this earth after death (i.e., a belief in reincarnation) and how the world might end may explain more positive attitudes toward the environment. Participants were 533 self-identified Christians and Hindus in the United States and India who completed an online survey assessing religiosity, positive attitudes towards environmentalism, afterlife beliefs, and eschatological beliefs. Christians showed significantly lower ratings of environmentalism compared with Hindus. There were also significant negative differences found based on beliefs about heaven, eschatology beliefs, and increased religiosity in Christians, and significant positive differences found based on reincarnation, eschatology beliefs, and increased religiosity in Hindus. Overall, these results suggest that Christians are less likely to have positive attitudes toward environmentalism compared with Hindus, and that beliefs about the afterlife and the end of the world were significant predictors of environmentalist attitudes.

Telemedicine is a multipurpose tool that allows medical professionals to use technology as a means to evaluate, diagnose, and treat patients remotely. This paper focuses on the challenges that developing telemedicine programs face, specifically discussing target population, user experience, and physician adoption. Various users of telemedicine share their experiences overcoming such challenges with the greater goal of this paper being to facilitate the growth of telemedicine programs.

Description
For centuries, religion has been a part of people's lives, impacting their well-being. Well-being includes both positive and negative emotions that make people feel satisfied. Religion can affect how people handle their physical health, social behavior, support, and stress. Interestingly, more people have been abandoning religion since 1990, even though it has positive effects on well-being. In this study, I sought to understand the extent to which leaving religion is associated with all aspects of well-being, including spiritual well-being. I asked 606 Arizona State University undergraduates to rate their well-being from two different time periods in their life. Participants were first asked if they were currently religious or nonreligious;135 said they had left/changed religions. If participants indicated that they did not leave/change religions, they were asked about their well-being before and after starting at ASU. I examined perceived change in well-being to understand how religion can influence many aspects of an individual’s life. Leaving or changing religion was positively associated with well-being. Those who reported leaving religion reported better environmental, emotional, social, educational, occupational, and spiritual well-being. In the control group (ASU), educational and spiritual well-being had a significant increase, which is interesting. The results showed that changing/leaving religion had a positive association on well-being.
