Description
The economic crisis in 2008 triggered a global financial shockwave that left many wondering about the origins of the crisis. Similarly, in the early twentieth century, Wall Street faced catastrophic losses that set the stage for the Great Depression, which resulted in a decade of economic depression, leaving millions of people out of work. Using discourse analysis to understand how economic crisis is framed through the mainstream press, this research project analyzed the stock market crash of 1929-1932 and the mortgage-backed financial crisis of 2007-2009 through the lens of two mainstream publications, The New York Times and The Wall Street Journal. Comparative analysis focused on explanations for the causes of the crises, attributions of blame, culprits, and proposed solutions emerging in news coverage of the 1929 panic and the 2007-2009 financial crises. Mainstream media accounts of the 2007-2009 crisis are then compared with `alternative media' accounts of crisis causes, culprits, and solutions. These comparative analyses are contextualized historically within economic paradigms of thought, beginning with the classical economists led by Adam Smith and transitioning to the Chicago School.

Description
Branding and brand management have been top management priorities in the hotel industry. Some researchers have concluded that strong branding would be an efficient way for hotels and hotel chains to differentiate themselves from each other. Recent studies have focused on the establishment of a brand equity model and the relevant causal relationships of the model. Most of these studies have used types of desirability scales examining the importance of individual factors in measuring brand equity. However, they ignore the trade-offs that affect and characterize choice. Particularly, the personal decision process implied by the hierarchical brand equity model is absent. This study proposed two alternative measures of brand equity, analytic hierarchy process (AHP) and conjoint analysis (CA), to address these limitations. The AHP and the CA were compared using several validity measures to aid in selecting efficient methods. This study examined the validity of AHP and CA under two data collection methods applied to hotel branding: paper-based survey and online survey. Result showed that the AHP data collection methods were easier, as well as with respect to saving time and costs. Results also indicated that the AHP is equivalent to the CA with respect to predictive accuracy. Practical differences for hotel branding in attribute preferences were clearly observed between the AHP and the CA. The AHP results were consistent with previous studies by awarding high importance to perceived quality and brand loyalty and lower importance to brand awareness and brand image. Managerial implications were provided for results. In terms of practicality in data collection, the study results revealed that the data gathered online leads to a slightly lower internal and predictive validity. A limitation of this study was that the two methods were not perfectly comparable. Nevertheless, the validity of both AHP and CA seems satisfactory for both methods. The study results also offer useful perspectives to consider when choosing between the two methods, as well as between AHP and CA.

Description
The goal of the present study was to test for links between experiences of red flags in initial interactions with romantic partners and later styles of relational conflict. Red flags are negative qualities or traits displayed by a potential romantic partner that trigger warnings in singles of possible future negative experiences if a romantic relationship develops. I focused on five red flags (displayed a lack of interest, evidenced narcissistic-like behavior, was too sexual, too possessive, or drank too much) and three conflict styles (mutual constructive style, demand/withdraw style, mutual avoidance style) in the current study. The 155 unmarried male undergraduates and the 504 unmarried female undergraduates were asked to refer back to their most recent dating partner when completing these relationship measures. The red flag measures, therefore, were measured using a retrospective approach. After controlling for whether the singles were still in their relationships and the sex of the participants, regression analyses revealed that recalling that one's partner showed a lack of interest in initial interactions were significantly and positively associated with a demand/withdraw and mutual avoidant conflict style. Results also showed that recalling that one's partner was too possessive in initial interactions was significantly and negatively associated with a mutual constructive conflict style, and positively related to partner demand/I withdraw and mutual avoidant conflict styles. Finally, recalling that their partner drank too much in a first interaction was negatively linked to later reports of engaging in a mutually constructive conflict style. This study provides insight into an area of research that has not been previously studied.

Description
The coordination of group behavior in the social insects is representative of a broader phenomenon in nature, emergent biological complexity. In such systems, it is believed that large-scale patterns result from the interaction of relatively simple subunits. This dissertation involved the study of one such system: the social foraging of the ant Temnothorax rugatulus. Physically tiny with small population sizes, these cavity-dwelling ants provide a good model system to explore the mechanisms and ultimate origins of collective behavior in insect societies. My studies showed that colonies robustly exploit sugar water. Given a choice between feeders unequal in quality, colonies allocate more foragers to the better feeder. If the feeders change in quality, colonies are able to reallocate their foragers to the new location of the better feeder. These qualities of flexibility and allocation could be explained by the nature of positive feedback (tandem run recruitment) that these ants use. By observing foraging colonies with paint-marked ants, I was able to determine the `rules' that individuals follow: foragers recruit more and give up less when they find a better food source. By altering the nutritional condition of colonies, I found that these rules are flexible - attuned to the colony state. In starved colonies, individual ants are more likely to explore and recruit to food sources than in well-fed colonies. Similar to honeybees, Temmnothorax foragers appear to modulate their exploitation and recruitment behavior in response to environmental and social cues. Finally, I explored the influence of ecology (resource distribution) on the foraging success of colonies. Larger colonies showed increased consistency and a greater rate of harvest than smaller colonies, but this advantage was mediated by the distribution of resources. While patchy or rare food sources exaggerated the relative success of large colonies, regularly (or easily found) distributions leveled the playing field for smaller colonies. Social foraging in ant societies can best be understood when we view the colony as a single organism and the phenotype - group size, communication, and individual behavior - as integrated components of a homeostatic unit.

Description
This dissertation examined sojourner adjustment success utilizing a unique method for collecting and analyzing the perceptions and sense making of the sojourner participants. Although previous research studies in this area have mostly relied on quantitative survey designs and researcher-generated models, this study relied on in-depth, participant-driven, qualitative interviews that were semi-structured using a software-assisted method called Interpretive Structural Modeling (ISM). Through this dissertation research, study abroad students (sojourners) had the opportunity to reflect on their sojourn experience, share their adjustment stories, and identify factors that were personally relevant to their success. This study broke new ground while building on the vast body of work in cross-cultural and sojourner adjustment. Sojourners were asked to provide their perspectives on the relationships among those factors reported in the literature that are commonly believed to influence successful adjustment. This allowed me to connect existing literature on the subject with the lived experience of the sojourner participants. This dissertation sought to answer two research questions. First, what factors do participants identify as being keys to the success of their sojourn? Second, what relationships do participants perceive among the factors contributing to successful sojourner adjustment? This dissertation found that language proficiency played a key role in their adjustment and openness was the factor most selected by participants in their explanation of a successful sojourn. Additionally, participant profiles and influence structure summaries provided evidence of the relationships participants saw among success factors in their lived experiences. In terms of preparing sojourners for going abroad, analysis of the composite structure revealed what could be prioritized in pre-departure training for impending sojourners. Themes emerged which provide insight into the commonalities of the sojourner experience despite differences in one's program or personality. This dissertation also explained additional success factors participants identified (e.g., ability to manage language fatigue, creation of connections with other travelers) that were not initially provided to them. Finally, suggestions for study abroad students/coordinators, researchers, and employers are provided.

Description
The purpose of this study was to measure the effect of gendered communication on women's behavioral intentions regarding nonprofit and for-profit entrepreneurship. Women represent half of the U.S. workforce, but only about one third of all American entrepreneurs are women. Feminists have argued that because entrepreneurship is largely understood as a masculine activity, women — who are predominantly socialized to espouse a feminine gender role — are less likely to become entrepreneurs. Previous scholarship and the particular theoretical lens of social feminism suggest that communication about entrepreneurship that is congruent with a feminine gender role would lead to the recruitment of a greater number of women entrepreneurs. Findings of the current study, however, suggested the opposite, providing support for poststructuralist feminist theory. Women who viewed a feminine entrepreneurship recruiting brochure about entrepreneurship reported themselves to be more feminine and less likely to report intentions to become entrepreneurs than women who viewed a masculine entrepreneurship recruiting brochure. These findings suggested that feminine communication may prime women to think of themselves as feminine, which may then lead them to view themselves as not masculine enough to be entrepreneurs. The applications of these findings stretch beyond engaging more women in entrepreneurship and also extend to scholarship that investigates gender's effects on women's pursuit of other masculine careers, including those in science, technology, engineering, and mathematics. Until the larger discourse on entrepreneurship changes to be inclusive of femininity, it is unlikely that strategies that feminize entrepreneurial activity in controlled situations will have an effect on changing the patterns of women's entrepreneurial intentions.

Description
The present study focused on those who had recently been involved in a romantic relationship that ended in a breakup. Data was collected from 326 participants using an online questionnaire. Participants were asked questions about goal linking, rumination, self-efficacy, Facebook ORI behaviors, and emotional response questions. The results indicated that there were two types of Facebook ORI behaviors: explicit and covert. Explicit ORI was predicted by self-efficacy among those whose partner ended the relationship, as well as goal linking when the breakup was self-initiated. Covert ORI was predicted by rumination across all levels of breakup initiator (self, partner, or mutual). Moreover, only general negative emotions predicted Covert ORI, but general negative emotion and positive emotion predicted Explicit ORI. Finally, the results showed that those who were broken up with engaged in more Covert ORI behaviors than those who ended the relationship themselves or who mutually ended the relationship. These results suggest that Relational Goal Pursuit theory, which is commonly used to explain ORI behavior, be reconceptualized.

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
With growing complexity of power grid interconnections, power systems may become increasingly vulnerable to low frequency oscillations (especially inter-area oscillations) and dependent on stabilizing controls using either local signals or wide-area signals to provide adequate damping. In recent years, the ability and potential to use wide-area signals for control purposes has increased since a significant investment has been made in the U. S. in deploying synchrophasor measurement technology. Fast and reliable communication systems are essential to enable the use of wide-area signals in controls. If wide-area signals find increased applicability in controls the security and reliability of power systems could be vulnerable to disruptions in communication systems. Even though numerous modern techniques have been developed to lower the probability of communication errors, communication networks cannot be designed to be always reliable. Given this background the motivation of this work is to build resiliency in the power grid controls to respond to failures in the communication network when wide-area control signals are used. In addition, this work also deals with the delay uncertainty associated with the wide-area signal transmission. In order to counteract the negative impact of communication failures on control effectiveness, two approaches are proposed and both approaches are motivated by considering the use of a robustly designed supplementary damping control (SDC) framework associated with a static VAr compensator (SVC). When there is no communication failure, the designed controller guarantees enhanced improvement in damping performance. When the wide-area signal in use is lost due to a communication failure, however, the resilient control provides the required damping of the inter-area oscillations by either utilizing another wide-area measurement through a healthy communication route or by simply utilizing an appropriate local control signal. Simulation results prove that with either of the proposed controls included, the system is stabilized regardless of communication failures, and thereby the reliability and sustainability of power systems is improved. The proposed approaches can be extended without loss of generality to the design of any resilient controller in cyber-physical engineering systems.

Description
This qualitative study examines the major changes in relationship closeness of married couples when one spouse acquires a vision disability. Turning Points analysis and Retrospective Interview Technique (RIT) were utilized which required participants to plot their relational journey on a graph after the onset of the disability. A sample of 32 participants generating 100 unique turning points and 32 RIT graphs lent in-depth insight into the less explored area of the impact of a visual disability on marital relationships. A constant comparison method employed for the analysis of these turning points revealed six major categories, which include Change in Relational Dynamics, Realization of the Disability, Regaining Normality in Life, Resilience, Reactions to Assistance, and Dealing with the Disability. These turning points differ in terms of their positive or negative impact on the relational closeness between partners. In addition, the 32 individual RIT graphs were also analyzed and were grouped into four categories based on visual similarity, which include Erratic Relational Restoration, Erratic Relational Increase, Consistent Closeness and Gradual Relational Increase. Results provide theoretical contributions to disability and marriage literature. Implications for the application of turning points to the study of post-disability marital relationships are also discussed, and research directions identified.
