Context in Mobile System Design: Characterization, Theory, and Implications
Context information brings new opportunities for efficient and effective applications and services on mobile devices. Many existing work exploit the context dependency of mobile usage for specific applications, and show significant, quantified, performance gains by utilizing context. In order to be practical, such works often pay careful attention to the energy and processing costs of context awareness while attempting to maintain reasonable accuracy. These works also have to deal with the challenges of multiple sources of context, which can lead to a sparse training data set.
Even with the abundance of such work, quantifying context-dependency and the relationship between context-dependency and performance achievements remains an open problem, and solutions to manage the and challenges of context awareness remain ad-hoc. To this end, this dissertation methodologically quantifies and measures the context dependency of three principal types of mobile usage in a methodological, application agnostic yet practical manner. The three usages are the websites the user visits, the phone numbers they call, and the apps they use, either built-in or obtained by the user from the App Store . While this dissertation measures the context dependency of these three principal types of mobile usage, its methodology can be readily extended to other context-dependent mobile usage and system resources. This dissertation further presents SmartContext, a framework to systematically optimize the energy cost of context awareness by selecting among different context sources, while satisfying the system designerβs cost-accuracy tradeoffs. Finally, this thesis investigates the collective effect of social context on mobile usage, by separating and comparing LiveLab users based on their socioeconomic groups.
The analysis and findings are based on usage and context traces collected in real-life settings from 24 iPhone users over a period of one year. This dissertation presents findings regarding the context dependency of three principal types of mobile usage; visited websites, phone calls, and app usage. The methodology and lessons presented here can be readily extended to other forms of context and context-dependent usage and resources. They guide the development of context aware systems, and highlight the challenges and expectations regarding the context dependency of mobile usage

The Effect of Cognitive Behavioral Group Therapy on Body Image, Attachment Style and Emotion Regulation in Women with Eating Disorder
The purpose of this study is to explain the effect of cognitive behavioral therapy on body image, attachment style, and emotion regulation in women with eating disorders. The present paper is a quasi-experimental study of "pretest-posttest with control group design" and was applied research based on the aim. The statistical population includes 470 women who attended nutrition clinics, psychiatric centers, and bodybuilding and aerobics clubs in areas 1, 3, 6, and 21 of Tehran in 20219. The sample includes 30 women with eating disorders who attended the above centers in 2019. They were selected by Convenience Sampling and randomly divided into control and experimental groups. Patients in the intervention group received 12 sessions of two-hour CBT group therapy over a 12-week period. Patients in the control group remained on the waiting list. Participants answered the Adult Attachment Inventory (AAI), Difficulty in Emotion Regulation Scale (DERS), and Satisfaction with Body Image (SWBI) questionnaires in the pretest and posttest phases. We used ANCOVA and the T-test for independent samples to test the research hypotheses. SPSS version 26 was used for data analysis. The results of ANCOVA showed a significant effect of cognitive-behavioral group therapy on body image (F= 6.632, p= 0.016), emotion regulation (F= 57.423, p=0.001), and secure attachment style (F=6.250, p= 0.019). In addition, the results of the Independent Sample T-test showed that cognitive behavioral therapy had a significant effect on avoidance attachment style (t= 3.272, p= 0.006) and ambivalence attachment style (t= 4.570, p=0.001). The present study demonstrated that cognitive behavioral group therapy improved body image, attachment style, and emotion regulation in women with eating disorders, and that this type of treatment may be a useful therapy for women with eating disorders
