Fresh start: a group-based intervention to promote physical activity among college freshman

Master of ScienceDepartment of KinesiologyEmily MaileyPhysical activity levels tend to decline as students transition from high school to college, and freshmen college women may be particularly susceptible to physical activity barriers. It is possible that providing physical activity resources and support via text messages could assist freshmen women in increasing their physical activity levels. The primary purpose of this study was to evaluate the effects of a mobile group-based intervention for freshmen female college students on physical activity and sedentary behavior. In addition, we examined intervention effects on social support, enjoyment, and stress in this population. Freshmen females (n=30) were recruited to participate in a 9-week intervention that involved wearing a physical activity monitor for three individual weeks (week 0, week 5, and week 9) and receiving tailored weekly messages via GroupMe. Participants were randomly assigned to groups of 6-7 participants, and each group was moderated by one research assistant. GroupMe discussions were specifically formatted to provide physical activity social support, promote physical activity enjoyment, enhance knowledge about benefits of physical activity, suggest ways to decrease sedentary behavior, and increase awareness of various physical activity resources on campus, such as the recreational center. Outcomes were assessed at baseline and post-intervention. Additionally, follow-up focus group sessions were conducted during the fall semester of the participants’ sophomore year to gain further feedback about the intervention. We hypothesized that students would demonstrate increases in physical activity, enjoyment, and social support, and decreases in sedentary behavior and stress after participating in the intervention. Results revealed no significant changes in physical activity or sedentary behavior based on objective data from the activPALs. A Wilcoxon Signed-Rank Test of self-reported physical activity and sedentary behavior (International Physical Activity Questionnaire) indicated increases in self-reported sitting time from baseline to post-intervention (Z=-2.654, p<0.008). There were no significant changes in enjoyment, social support, or stress from baseline to post-intervention. A total of 10 participants attended a follow-up focus group session. Key recommendations included incorporating more face to face interaction, a change of topics within the messages to focus on more nutrition and exercise and or guided exercises, and running the intervention during the fall semester rather than the spring. Aspects of the program that participants liked the best included the feedback of activity provided by the activPAL, the idea of using GroupMe for the program, and the length of the program. Overall, results did not align with our hypotheses, but the intervention results and feedback from participants will help with intervention refinement. Future studies should continue to seek creative ways to promote physical activity in this population, with an overall purpose of sustaining physical activity habits beyond the intervention

HitFraud: A Broad Learning Approach for Collective Fraud Detection in Heterogeneous Information Networks

On electronic game platforms, different payment transactions have different levels of risk. Risk is generally higher for digital goods in e-commerce. However, it differs based on product and its popularity, the offer type (packaged game, virtual currency to a game or subscription service), storefront and geography. Existing fraud policies and models make decisions independently for each transaction based on transaction attributes, payment velocities, user characteristics, and other relevant information. However, suspicious transactions may still evade detection and hence we propose a broad learning approach leveraging a graph based perspective to uncover relationships among suspicious transactions, i.e., inter-transaction dependency. Our focus is to detect suspicious transactions by capturing common fraudulent behaviors that would not be considered suspicious when being considered in isolation. In this paper, we present HitFraud that leverages heterogeneous information networks for collective fraud detection by exploring correlated and fast evolving fraudulent behaviors. First, a heterogeneous information network is designed to link entities of interest in the transaction database via different semantics. Then, graph based features are efficiently discovered from the network exploiting the concept of meta-paths, and decisions on frauds are made collectively on test instances. Experiments on real-world payment transaction data from Electronic Arts demonstrate that the prediction performance is effectively boosted by HitFraud with fast convergence where the computation of meta-path based features is largely optimized. Notably, recall can be improved up to 7.93% and F-score 4.62% compared to baselines.Comment: ICDM 201

The Effects of Christianity on Adult Resiliency when Overcoming Grief

Grief seems to affect everyone in some way over the course of life. This research conducted a thematic analysis using grounded theory methods to understand the process in which Christians overcome grief when losing a loved one. A total of six participants volunteered to be able to share their stories. The questions to be answered included: “What is the process of growing resilience among Christians who experience grief due to losing a loved one?” and “How does one’s faith impact this process of overcoming grief?” Utilizing Strauss and Corbin (1990), the data collected in this study was analyzed by open, axial, and selective coding. From the data, two selective codes emerged: 1) Enduring the struggles of grief as it leads to hope and resilience and 2) Christian faith cultivates and strengthens resilience. Christians go through a phase of struggles in which they depend on their faith to navigate through the difficulties of grief to gain resilience

Sema as Zikr: The Language of the Whirling Dance

This paper explores the parallels found in the dance of the whirling dervishes and Rumi’s poetry. The dance, or sema, is a remembrance of God, zikr, which Rumi beautifully describes in his poetry. It is an honoring and mirroring of the revolutions, cycles, circles, centers, and turnings of life. This poetry in motion, done in the silence of the dervish, brings us to the sema, as a pronounced capacity topresence, because it is both poetry and thing. As poetry, it affords us to undergo an experience with language and the silence that bring us nearer to our center. There is much that is said in the sema even if nothing is spoken. What is said is heard in the silence cultivated by sema. The dance of the whirling dervishes is zikr, a remembrance of God.
