Description
The problem of the study was to investigate constraints and facilitators of Mexican American parents when deciding whether or not to enroll their children in formal swim lessons as a means of drowning prevention. The information obtained by this study (1) helps create awareness about youth drowning incidents and (2) provides insight about Mexican American perspectives and behaviors toward drowning prevention through, or not through as the case may be, youth formal swim lesson participation. This study's sample was purposively selected using typical case and snowball sampling techniques. Individual interviews were conducted with Mexican American parent participants and focus group interviews were conducted with aquatic personnel. From April to August, individual and focus group interviews were conducted in the border towns Sierra Vista, Bisbee, and Douglas in the state of Arizona. There were a total of 25 Mexican American parent participants: 10 had never enrolled their children in swim lessons and 15 had experience enrolling and observing their children in swim lessons. There were 3 focus groups interviews of aquatic personnel experts: Sierra Vista had 6, Bisbee had 7 and Douglas had 9 participants. The theory used to identify and classify the types of constraints and facilitators described in the findings of this study was the Leisure Constraints Theory proposed by Crawford, Jackson and Godbey, 1991. Finding from this study suggest that despite the uncommon perception, Mexican Americans youth are actually participating more in formal swim lessons than they have in past generations. Mexican American families in this sample reported major constraints for formal swim lessons as a reliance on learning form family and friends, swimming at private pools, money, time, and transportation as barriers to participation. Facilitators for Mexican American youth to participate in formal swim lessons are youth drowning awareness, education, lack of parental swimming ability, generational social norm behavior changes, financial assistance and an attitude shift in favor of formal swim lessons.

Description
In order to be competitive in the hotel market, more and more hotels have proposed various types of "wow" services to inform customers' impressions of the hotel in a positive way. Many customers consider these services excellent, and they often exceed their expectations. However, some "wow" services only generate the effect of amazement instead of meeting customers' needs and wants. Applying the notion of the Zone of Tolerance (ZOT: the range between customers' desired and adequate levels of service expectations) to the unique services provided by the Hotel Royal Chiao Hsi Spa in Taiwan, this research study explores hotel customers' service expectations and perceived service quality while revealing the relationship between service quality, satisfaction, and future behavioral intentions. The findings indicate that the ZOT indeed exists in customers' service expectations through the significant difference between the desired and adequate levels of expectations. In addition, findings indicate that customers have diverse tolerance zones toward different hotel services regarding the perceived level of essentialness. Ultimately, the findings specify that customers' perceived service quality has a direct effect on both customer satisfaction and future behavioral intentions.

Description
This research is focused on competitive female video gamers. This study focuses on a specific group of competitive female gamers who participate in an all female online community group or clan known as the PMSclan. The purpose of the study is to analyze the highly competitive female video gaming clan members of the PMSclan in order to understand how resistance is displayed in a female centered video gaming community and how that affects the identity of the individual gamers through Shaw's (2001) theory of resistance. This study employs qualitative research design and uses content analysis of publicly available clan doctrines and member blogs through the PMSclan website. Findings indicate that collective acts of resistance lead to individual acts of resistance which can be seen through self-expression, self-determination, and empowerment. These acts of resistance have a positive impact on female gamers with outcomes of strength and power which can be displayed in a typically masculine society.

Description
Within the media there is an abundance of reports that claim tourists are being harassed, kidnapped and even killed in some instances as a result of their representation of their country's political ideology and international relations. A qualitative study was undertaken in Bolivia to determine how a tourist avoids or copes with the fear of severe political retribution or harassment in a country whose political environment is largely opposed to that of the traveler's home country. Interviews were conducted in multiple regions of Bolivia, and the data were coded. The results show that tourists experience political retribution on a much smaller scale than initially thought, usually through non-threatening social encounters. The overall themes influencing traveler behaviors are the (Un)Apologetic American, the George W. Bush foreign policy era, avoiding perceived unsafe countries or regions, and Bolivian borders. Respondents, when asked to reflect upon their behavioral habits, do not usually forthrightly deny their country of origin but merely adapt their national identities based on their familial origins, dual citizenship, language abilities or lack thereof, familiarity with the world/regional politics or lack thereof and associating oneself with a popular region in the United States (e.g. New York), rather than the US as a whole. Interestingly, none of the Americans interviewed candidly deny their American nationality or express future intention to deny their nationality. The Americans did express feeling "singled out" at the Bolivian borders which leads to the management implication to implement an automated receipt when purchasing a Bolivian visa and improving the Ministry of Tourism website that would more clearly state visa requirements. Additionally, the image of Bolivia as a culturally and politically homogeneous country is discussed.

Description
Efficiency of components is an ever increasing area of importance to portable applications, where a finite battery means finite operating time. Higher efficiency devices need to be designed that don't compromise on the performance that the consumer has come to expect. Class D amplifiers deliver on the goal of increased efficiency, but at the cost of distortion. Class AB amplifiers have low efficiency, but high linearity. By modulating the supply voltage of a Class AB amplifier to make a Class H amplifier, the efficiency can increase while still maintaining the Class AB level of linearity. A 92dB Power Supply Rejection Ratio (PSRR) Class AB amplifier and a Class H amplifier were designed in a 0.24um process for portable audio applications. Using a multiphase buck converter increased the efficiency of the Class H amplifier while still maintaining a fast response time to respond to audio frequencies. The Class H amplifier had an efficiency above the Class AB amplifier by 5-7% from 5-30mW of output power without affecting the total harmonic distortion (THD) at the design specifications. The Class H amplifier design met all design specifications and showed performance comparable to the designed Class AB amplifier across 1kHz-20kHz and 0.01mW-30mW. The Class H design was able to output 30mW into 16Ohms without any increase in THD. This design shows that Class H amplifiers merit more research into their potential for increasing efficiency of audio amplifiers and that even simple designs can give significant increases in efficiency without compromising linearity.

Description
Playing tennis professionally is a stressful profession. However, it has the potential to be even more stressful for players who must move from their home country in order to train. If not dealt with, these stresses have the potential of causing many negative outcomes, including increasing levels of distress, in these professional tennis players. It is known that resources play a role in reducing or buffering levels of stress and distress among individuals, but there are competing theories as to how this occurs. Using Ensel and Lin's models of stress processes, this is an exploratory study that identifies the stresses and distresses professional Taiwanese tennis players face and the resources they use to cope. Participants included in this study are professional Taiwanese tennis players (2 males and 2 females) who continuously attend national and international tennis competitions and have both domestic and world ranks. Results from the semi-structured interviews revealed that challenges, frustration, resources, and toughness were four general themes to describe stresses and distresses professional Taiwanese tennis players face and the resources they use to cope. Future research for professional tennis players is also discussed.

Description
Thousands of children are being injured every day in bicycling accidents. Interventions, like Safe Routes to School, are currently in place to combat injury rates by providing programs to teach children safe biking behaviors. In order to develop effective behavioral change programs, behavior and the components of which it is composed must be understood. Attitudes, subjective norms, and self-efficacy are important predictors of intention to perform a behavior. The purpose of this study was to ascertain the extent to which attitude, subjective norms, self-efficacy, and bike rodeo participation explain third through eighth graders' intentions to bike safely. These constructs were tested using a survey research design in a purposive sample of fifty-seven third through eighth grade students in Safe Routes to School schools in the Southwest. Students took an online survey in the computer lab at their respective schools supervised by a teacher. The study found attitudes to be comprised of three factors: happy/safe, not afraid, and calm. Overall, the model explained approximately 71% of the variance in children's intentions to bike safely, R2=.749, Adjusted R2=.713, F(7, 49)=20.854, p<.01. The significant predictors were happy/safe attitudes, subjective norms, self-efficacy, and a quadratic self-efficacy term explaining 10% (p=.019), 28% (p<.01), 18% (p<.01), and 15% (p<.01) respectively. The results of the study can be used to create future and improve current bike safety interventions for children.

Description
The objective of this study was to understand domestic and foreign-born housekeeper's individual perceptions of labor mobility and job satisfaction related to their jobs within the hospitality industry. Literature regarding the bridging of tourism, immigration, and labor supply was addressed to expose broad conceptual frameworks that lead to the development of this study. More specifically, literature regarding labor mobility within tourism industries, migrant decision making, and barriers to mobility and immigration helped to construct a narrowed conceptual framework specific to hospitality labor in Phoenix, Arizona. Similar and previous studies focused on perceived labor mobility during significant economic or industry shifts. This study included the addition of a policy factor to help determine to what degree state policy change effected hospitality workers' perceived labor mobility. Arizona's recently passed and implemented legislative act SB1070 regards immigrant identification and employment, and enforcement of the act in the state of Arizona; this serves as the implicated policy change. Data were collected via on-site survey administered February to May 2011. An overall score was created for the five motivational dimensions: 1 — Status; 2 — Economic; 3 — Refugee; 4 — Entrepreneurial; and, 5 — Political using principle component factor analysis using a varimax rotation with Kaiser normalization. Theory and literature suggest that the economic advancement, status advancement, and the refugee orientation are effective explanatory variables for motivating a career move into the tourism industry. A total of 82 questionnaires were delivered and completed (N = 82), and none were eliminated. The statistically-determined Economic Dimension was characterized by eleven statements explained 51% of the variation and was the overwhelming motivational force. The average coded response for change in job satisfaction was very positive at .75. Ten features of changes in job satisfaction were used as the basis of the second measure of change in job satisfaction. The first Principle Component of the ten features of job satisfaction change explained 45% of the variation in these features and loadings were positive near or above 0.60 for all items. The relationship between variations in each of the measurements of change in job satisfaction and motivating factors was explored using regression analysis. The two dependent variables were Overall Change and First Principle Component, and the independent variables for both regressions included the four motivating factors as measured by the rotated factors scores to represent dimensions of Economic, Status, Refugee and Entrepreneurial. In addition to the motivational factors, four demographic variables were included as independent variables to account for personal and situational differences. None of the regression coefficients were significant at even the 10% level. Although this result was expected, the positive sign of regression coefficients suggest that expectations of working as a housekeepers results in a positive outcome. Understanding this relationship further is necessary, and seeking larger sample sizes over a longer period of time would be most beneficial to this field of research.

Description
Incentive travel continues to grow as a form of motivation in the work place. However, there is little research that has examined future potential incentive travelers' wants and needs from an incentive travel trip. The purpose of this study was to understand how and in what way various potential incentive travelers' beliefs, including attitudes, subjective norm, perceived behavioral control and motivation, influence their future inclusion of a significant other on an incentive travel trip using a modified theory of planned behavior. Moreover, the potential moderating effect of past inclusion of a significant other experience was examined as well. The study collected 129 usable responses from potential incentive travelers from companies based in Iowa and Arizona. The research for this project was conducted through online questionnaires that included quantitative and qualitative questions. The study used exploratory factor analysis (EFA), Pearson's correlation and multiple regression to test study hypotheses. The results of the multiple regression indicated three constructs, attitudes, subjective norm and motivation appeared to be statistically significant, while perceived behavioral control was not statistically significant in predicting potential incentive travelers' intended inclusion of a significant other. Perceived behavioral control was not significant because the control of including a significant other is dependent on the participant's employer. Pearson's correlation found a moderating effect of past inclusion of a significant other on subjective norm and perceived behavioral control. In conclusion, the results validated the theory of planned behavior in the context of incentive travelers' inclusion of a significant other.

Description
Class D Amplifiers are widely used in portable systems such as mobile phones to achieve high efficiency. The demands of portable electronics for low power consumption to extend battery life and reduce heat dissipation mandate efficient, high-performance audio amplifiers. The high efficiency of Class D amplifiers (CDAs) makes them particularly attractive for portable applications. The Digital class D amplifier is an interesting solution to increase the efficiency of embedded systems. However, this solution is not good enough in terms of PWM stage linearity and power supply rejection. An efficient control is needed to correct the error sources in order to get a high fidelity sound quality in the whole audio range of frequencies. A fundamental analysis on various error sources due to non idealities in the power stage have been discussed here with key focus on Power supply perturbations driving the Power stage of a Class D Audio Amplifier. Two types of closed loop Digital Class D architecture for PSRR improvement have been proposed and modeled. Double sided uniform sampling modulation has been used. One of the architecture uses feedback around the power stage and the second architecture uses feedback into digital domain. Simulation & experimental results confirm that the closed loop PSRR & PS-IMD improve by around 30-40 dB and 25 dB respectively.
