Description
The purpose of this paper is to introduce a new method of dividing wireless communication (such as the 802.11a/b/g
and cellular UMTS MAC protocols) across multiple unreliable communication links (such as Ethernet). The purpose is to introduce the appropriate hardware, software, and system architecture required to provide the basis for a wireless system (using a 802.11a/b/g
and cellular protocols as a model) that can scale to support thousands of users simultaneously (say in a large office building, super chain store, etc.) or in a small, but very dense communication RF region. Elements of communication between a base station and a Mobile Station will be analyzed statistically to demonstrate higher throughput, fewer collisions and lower bit error rates (BER) with the given bandwidth defined by the 802.11n wireless specification (use of MIMO channels will be evaluated). A new network nodal paradigm will be presented. Alternative link layer communication techniques will be recommended and analyzed for the affect on mobile devices. The analysis will describe how the algorithms used by state machines implemented on Mobile Stations and Wi-Fi client devices will be influenced by new base station transmission behavior. New hardware design techniques that can be used to optimize this architecture as well as hardware design principles in regard to the minimal hardware functional blocks required to support such a system design will be described. Hardware design and verification simulation techniques to prove the hardware design will accommodate an acceptable level of performance to meet the strict timing as it relates to this new system architecture.

Description
Voice and other circuit switched services in a LTE deployment can be based on a Circuit Switched Fall Back mechanism or on the upcoming Voice Over LTE option. Voice Over LTE option can be used with its SIP based signaling to route voice calls and other circuit switched services over the LTE's packet switched core. The main issue that is faced though is the validation of this approach before the deployment over commercial network. The test strategy devised as a result of this work will be able to visit corner scenarios and error sensitive services, so that signaling involved can be verified to ensure a robust deployment of the Voice Over LTE network. Signaling test strategy is based on the observations made during a simulated Voice Over LTE call inside the lab in a controlled environment. Emergency services offered are carefully studied to devise a robust test strategy to make sure that any service failure is avoided. Other area were the service is routed via different protocol stack layer than it normally is in a legacy circuit switched core are identified and brought into the scope of the test strategy.

Description
The relationships between goals and specific flirting behaviors were investigated in a college population. Research questions and hypotheses were guided by Dillard's (1990) Goals-Plans-Action (GPA) model of interpersonal influence, which states that goals lead to planning processes, which, in turn, produce behavior. Six hundred and eighty-five undergraduates at a large southwestern university participated in an online survey assessing their behaviors in their most recent flirting interactions, their goals for that interaction, as well as measures designed to assess planning, the importance of the goal, and the number of goals present for the interaction. Results indicate that goals relate to the use of some, but not all behaviors, and that a flirting script may exist. Furthermore, planning, importance, and number of goals were all found to relate to the reporting of specific flirting behaviors. Sex differences were found as well, such that men reported using more forward and direct behaviors, while women reported using more facial expressions, self-touch, and laughing; men also reported flirting for sexual reasons more than women, and women reported flirting for more fun reasons that men. Overall, this study confirms the utility of the GPA framework for understanding the relationship between goals and flirting behavior, and suggests several avenues for future research.

Description
The division of domestic labor has far-reaching implications for "private" life (e.g. relational satisfaction and conflict) and for "public" paid labor (e.g. time and dedication in the workplace and career advancement). Although several theories have been developed and tested, they do not sufficiently explain the consistent findings that women in mixed sex households perform a majority of the domestic labor. Without understanding the causes for differences in task performance, past research encouraging communicative solutions to ameliorate conflict was ineffective in changing task allocation and performance. Therefore, it is necessary to understand theoretical explanations that drive domestic labor behavior to develop effective solutions. The recent integrative theory of the division of domestic labor attempts to explain how individuals interact with household partners to allocate domestic tasks. Recognizing the complexity of the division of domestic labor, the integrative theory considers individual, dyadic, and societal factors that influence task allocation. Because clear differences in task performance have been found in mixed sex households, this study separates sex and gender as distinct variables by considering same-sex roommate relationships, essentially removing sex differences from the living arrangement. Furthermore, this study considers individual threshold levels as described by the integrative theory in order to test the theoretical underpinnings. Specifically, this study is designed to investigate the relationships between individual cleanliness threshold levels and gender, sex, perceptions of satisfaction, equity, and frequency of conflict in same-sex roommate relationships. Results indicate support of the integrative theory of the division of domestic labor. Regarding gender differences, partial support for the theory appeared in that feminine individuals have lower threshold levels than masculine individuals. Regarding sex differences, women possess lower individual threshold levels (i.e. more bothered when a task is undone) compared to men, which likely accounts for why existing research indicates that women spend more time performing domestic tasks. What is more, individuals with higher threshold levels report greater relational satisfaction. Further, individuals whose threshold levels differ from their living partner report lower relational satisfaction and greater conflict frequency. Finally, in terms of equity, both overbenefited and underbenefited individuals experience more conflict than those who feel their relationship is equitable. These results provide theoretical support for the integrative theory of the division of labor. Furthermore, the development and testing of a threshold measure scale can be used practically for future research and for better roommate pairings by universities. In addition, communication scholars, family practitioners and counselors, and universities can apply these theoretically grounded research findings to develop and test strategies to reduce conflict and increase relational satisfaction among roommates and couples.

Description
Broaden and build theory (BBT; Fredrickson, 1998; 2001) postulates that positive emotions expand the scope of one's attention and thought-action repertoires (Fredrickson & Branigan, 2005). Within the boundaries of BBT, the undoing hypothesis (Fredrickson, 1998, Fredrickson & Levenson, 1998) argues that positive emotions themselves do not bring forth specific action tendencies or urges; therefore, they do not consequently require an increase in cardiovascular activity to carry out the urge. On the other hand, positive emotions have evolved to subdue the cardiovascular response previously initiated by negative emotions. This dissertation proposes that the real power of positive emotions might be to undo not the effects of negative emotions themselves, however, but simply reduce the arousal itself. This dissertation used minor physiological arousal (e.g., a step-stool task) to simulate the cardiovascular effects of the stress manipulations used in previous tests of the undoing hypothesis by Fredrickson and colleagues. This dissertation asks if positive emotions undo the cardiovascular reactivity of an emotionally neutral stimulus. Positive emotions were induced through one film clip (i.e., a happy film clip) and was compared to a neutral film clip (no emotion elicited). An experimental design measured the effects of arousal induction and film clip on participants' cardiovascular activity. Results indicated that positive emotions had the same effect as no emotions on participants' cardiovascular activity. Implications for theory and research are provided, as well as an assessment of the study's strengths and limitations. Finally, several directions for future research are offered.

Exploring factors influencing Chinese American older adults' intentions to plan for end-of-life care
Description
This study aimed to understand the factors that influence Chinese American older adults’ advance care planning (ACP) on end-of-life care. The Theory of Planned Behavior (TPB) and Health Belief Model (HBM) were primarily applied to explain Chinese American older adults’ intentions toward two behaviors: 1) discussion of end-of-life care plans with family members and 2) completion of an advance directive (AD). Additionally, acculturation and family cohesion were considered to examine their impacts on the TPB and HBM. A cross-sectional survey was conducted through face-to-face interviews on a sample of 298 community-dwelling Chinese-American adults aged 55 and older living in the metropolitan Phoenix area of Arizona. Based upon random assignment, 161 participants answered questions regarding discussing end-of-life care plans with family members, while 137 participants answered questions related to the completion of an AD. Hierarchical multiple regression analysis was used to focus on the influence of TPB and HBM measures on behavioral intentions toward the two behaviors. Results indicated that both the TPB and HBM had predictive power to explain the target population’s intentions. However, the predictability of TPB and HBM measures varied across the two behaviors. Acculturation moderated the relationship between attitudes and intentions to complete an AD negatively. Family cohesion moderated the relationship between perceived benefits and intentions to discuss end-of-life care plans with family members negatively. These findings would help inform future interventions for improving the target population’s ACP awareness and engagement.

Description
The commercial semiconductor industry is gearing up for 5G communications in the 28GHz and higher band. In order to maintain the same relative receiver sensitivity, a larger number of antenna elements are required; the larger number of antenna elements is, in turn, driving semiconductor development. The purpose of this paper is to introduce a new method of dividing wireless communication protocols (such as the 802.11a/b/g
and cellular UMTS MAC protocols) across multiple unreliable communication links using a new link layer communication model in concert with a smart antenna aperture design referred to as Vector Antenna. A vector antenna is a ‘smart’ antenna system and as any smart antenna aperture, the design inherently requires unique microwave component performance as well as Digital Signal Processing (DSP) capabilities. This performance and these capabilities are further enhanced with a patented wireless protocol stack capability.

Description
This study investigated work-family conflict and related phenomena reported by female teachers in primary and secondary schools in Kenya. Specifically, it sought to first identify general work and family stressors and profession specific stressors, and how these stressors influenced teachers’ work-family conflict (WFC) and burnout. Second, it investigated whether support from home and work reduced these teachers’ perceived work-family conflict and burnout. Third, it investigated the impact of marital status, number and ages of children, length of teaching experience, and school location (city vs town) on perceived work-family conflict (WFC).
In this study, 375 female teachers from Nairobi and three towns completed a survey questionnaire with both closed- and open-ended questions. Data analysis was conducted through descriptive and inferential statistics, and content analyses of qualitative data. There were five primary findings. (1) Teachers clearly identified and described stressors that led to work-family conflict: inability to get reliable support from domestic workers, a sick child, high expectations of a wife at home, high workloads at school and home, low schedule flexibility, and number of days teachers spend at school beyond normal working hours, etc.
(2) Work-family conflict experienced was cyclical in nature. Stressors influenced WFC, which led to adverse outcomes. These outcomes later acted as secondary stressors. (3) The culture of the school and school’s resources influenced the level of support that teachers received. The level of WFC support that teachers received depended on the goodwill of supervisors and colleagues.
(4) Work-family conflict contributed to emotional exhaustion, cynicism, and professional efficacy. Time and emotional investment in students’ parents was related to emotional exhaustion; time and emotional investment in students’ behavior, the number of years teaching experience, and number of children were related to professional efficacy. Support from teachers’ spouses enabled teachers to cope with cynicism.
(5) While marital status did not influence WFC, school location did; teachers in Nairobi experienced more WFC than those in small towns. The study highlighted the importance of culture in studies of work-family conflict, as some of the stressors and WFC experiences identified seemed unique to the Kenyan context. Finally, theoretical implications, policy recommendations, and further research directions are presented.

Description
Sexual violence is a problem on college campuses across that United States. In the past few years, federal and state legislation has been drafted in order to address campus sexual violence. A main feature of this legislation addresses an important communicative construct related to students’ sexual behavior: sexual consent. Colleges and universities are adopting an affirmative-standard of consent, which emphasizes that consent for sexual activity be communicated verbally or via unambiguous actions, mutual, voluntary, enthusiastic, and ongoing throughout the sexual encounter. Literature has explored how college students communicate and interpret sexual consent, but antecedents to sexual consent behaviors, particularly affirmative consent, are largely unknown.
The current investigation seeks to longitudinally explore the antecedents to college students’ affirmative sexual consent behaviors (i.e., nonverbal, initiating, verbal). Using the Theory of Planned Behavior (TPB) as a theoretical framework, hypotheses predicted that at Time 1 (T1) attitudes, norms, and perceived behavioral control would positively and significantly predict students’ (T1) intentions to communicate affirmative consent to their partner. Then, it was predicted that at Time 2 (T2)—thirty days later—intentions to communicate consent from T1 would positively and significantly predict college students’ communication of affirmative consent to their partner during their most recent sexual encounter. The final matched (i.e., completed T1 and T2 surveys) sample included two hundred twenty-five (N = 225) college students who had engaged in sexual activity during the 30 days between survey distributions. Results from the path analyses support the theoretically driven hypotheses for all three affirmative consent behaviors, and demonstrate that subjective norms and perceived control are important and strong determinants of students’ communication of affirmative sexual consent. Furthermore, multi-group invariance tested the potential moderating effects of three individual, two dyadic, and two environmental/contextual variables on the strength of path coefficients between TPB constructs for all three sexual consent behaviors. Only individual and environmental/contextual variables significantly moderated relationships within the TPB for the three models. Results are discussed with regard to theoretical implications as well as practical implications for university health educators and other health professionals. Additionally, limitations and future directions are noted.

Description
Background: This study examines how pro-vaccine flu messages, guided by the Extended Parallel Process Model (EPPM), affect parents’ intentions to vaccinate their children.
Methods: Parents of children six months to five years old (N = 975) were randomly exposed to one of four high-threat/high-efficacy messages (narrative, statistical, combined, control) and completed a follow-up survey. Differences between message conditions were assessed with one-way ANOVAs, and binary logistic regressions were used to show how constructs predicted intentions.
Results: There were no significant differences in the ANOVA results at p = .05 for EPPM variables or risk EPPM variables. There was a significant difference between message conditions for perceived manipulation (p = 0.026), authority, (p = 0.024), character (p = 0.037), attention (p < .000), and emotion (p < .000). The EPPM model and perceptions of message model (positively), and the risk EPPM model and fear control model (negatively), predicted intentions to vaccinate. Significant predictor variables in each model at p < .05 were severity (aOR = 1.83), response efficacy (aOR = 4.33), risk susceptibility (aOR = 0.53), risk fear (aOR = 0.74), issue derogation (aOR = 0.63), perceived manipulation (aOR = 0.64), character (aOR = 2.00), and personal relevance (aOR = 1.88). In a multivariate model of the significant predictors, only response efficacy significantly predicted intentions to vaccinate (aOR = 3.43). Compared to the control, none of the experimental messages significantly predicted intentions to vaccinate. The narrative and combined conditions significantly predicted intentions to search online (aOR = 2.37), and the combined condition significantly predicted intentions to talk to family/friends (aOR = 2.66).
Conclusions: The EPPM may not be effective in context of a two-way threat. Additional constructs that may be useful in the EPPM model are perceptions of the message and fear control variables. One-shot flu vaccine messages will be unlikely to directly influence vaccination rates; however they may increase information-seeking behavior. The impact of seeking more information on vaccination uptake requires further research. Flu vaccine messages should be presented in combined form. Future studies should focus on strategies to increase perceptions of the effectiveness of the flu vaccine.
