Description
The population of intellectually gifted youth encompasses a wide range of abilities, talents, temperaments, and personality characteristics. Although generalizations are often made outside of the empirical literature regarding the interpersonal skills of these children, much remains to be understood about their social behavior. The aim of this study was to examine the within-group differences of gifted children, and it was hypothesized that subgroups of the gifted population would differ from each other in terms of interpersonal skill development. Gifted education teachers within a large K-12 public school district in the Southwestern United States completed the Devereux Student Strengths Assessment (DESSA) regarding the social-emotional competence of 206 elementary and middle school students classified as gifted. Correlational analyses and factorial analysis of variance were conducted to compare interpersonal skills (as measured by DESSA ratings) and students' level of giftedness, area of identification as gifted, gender, and age. Results indicated that interpersonal skills were significantly related to gender, area of identification, and level of giftedness. Female children were described as having significantly higher levels of interpersonal skills overall, and children identified as gifted with both nonverbal and quantitative measures exhibited significantly higher levels of interpersonal skills than those identified with verbal or nonverbal measures alone. Significant correlations were also observed between the level of children's estimated gifted abilities and their interpersonal skills. Trends in the data suggested that as children's cognitive abilities increased, their interpersonal skills also increased, placing profoundly gifted children at social advantages over their moderately gifted peers. However, it was also noted that although the two variables were significantly related, they were not commensurate. While children presented with above-average cognitive abilities, their interpersonal skills were within the average range. This suggests that gifted children may benefit from interventions that target interpersonal skill development, in an effort to bring their social skills more in line with their cognitive abilities.

Description
A principal goal of this dissertation is to study wireless network design and optimization with the focus on two perspectives: 1) socially-aware mobile networking and computing; 2) security and privacy in wireless networking. Under this common theme, this dissertation can be broadly organized into three parts.
The first part studies socially-aware mobile networking and computing. First, it studies random access control and power control under a social group utility maximization (SGUM) framework. The socially-aware Nash equilibria (SNEs) are derived and analyzed. Then, it studies mobile crowdsensing under an incentive mechanism that exploits social trust assisted reciprocity (STAR). The efficacy of the STAR mechanism is thoroughly investigated. Next, it studies mobile users' data usage behaviors under the impact of social services and the wireless operator's pricing. Based on a two-stage Stackelberg game formulation, the user demand equilibrium (UDE) is analyzed in Stage II and the optimal pricing strategy is developed in Stage I. Last, it studies opportunistic cooperative networking under an optimal stopping framework with two-level decision-making. For both cases with or without dedicated relays, the optimal relaying strategies are derived and analyzed.
The second part studies radar sensor network coverage for physical security. First, it studies placement of bistatic radar (BR) sensor networks for barrier coverage. The optimality of line-based placement is analyzed, and the optimal placement of BRs on a line segment is characterized. Then, it studies the coverage of radar sensor networks that exploits the Doppler effect. Based on a Doppler coverage model, an efficient method is devised to characterize Doppler-covered regions and an algorithm is developed to find the minimum radar density required for Doppler coverage.
The third part studies cyber security and privacy in socially-aware networking and computing. First, it studies random access control, cooperative jamming, and spectrum access under an extended SGUM framework that incorporates negative social ties. The SNEs are derived and analyzed. Then, it studies pseudonym change for personalized location privacy under the SGUM framework. The SNEs are analyzed and an efficient algorithm is developed to find an SNE with desirable properties.
