In order to realize effective infotainment systems for vehicles, we need to have context-aware applications that use the latest (live) information for an enhanced user experience. Such up-to-date information is now abundantly available on the Internet, due to the explosive growth of the Web 2.0. In earlier times, it was difficult and expensive for vehicles to connect to the Internet. Recent advances in vehicular ad-hoc networks (VANETs) have enabled vehicles to connect to the Internet through road side infrastructures, with little to no additional cost. However, there are several problems with directly using Internet data in a vehicle, such as (1) Internet data sources have their own interfaces, which keep changing over time, needing frequent application updates, (2) information provided by multiple data sources needs to be preprocessed and fused before use, and (3) vehicles employ propriety platforms for infotainment systems, which makes an application update even more cumbersome. Furthermore, accessing multiple Internet sources may cause unnecessary overhead over the VANET bandwidth. In this thesis, we propose a cloud-based middleware framework for vehicular infotainment application development. The proposed framework follows service oriented architecture in which data filtering and fusion functionalities are delegated to the cloud. Data filtering and fusion reduce the data flow over VANET. Furthermore, because most the the processing is done on the cloud, the client becomes lightweight and loosely coupled with Internet resources and underlying platforms. We also propose a class based fusion method to combine information from multiple sources. The efficacy of the proposed framework is validated by developing an enhanced navigation (eDirection) application for the vehicle, as well as three infotainment applications: context-aware music, news, and weather.

Includes bibliographical references / The turn of the millennium witnessed the uptake and proliferation of mobile technology in developing regions. This occurrence has provided a medium for mobile telecommunication vendors within the region to create and offer services that are now accessible across socio-economic classes. A notable case of a widely adopted mobile technology-enabled service in the developing world is a mobile money service in Kenya called M-pesa. Since its inception, M-pesa has witnessed a mass adoption which has generally been attributed to prior lack of access by majority of individuals' in the country to affordable regulated financial services. M-pesa's presence has now been anticipated to afford a larger population the initial opportunity to harness economic benefits such as: increase money circulation, increase employment opportunities, facilitate social capital accumulation, facilitate savings, and promote financial autonomy, amongst others. Also, M-pesa based transactions in Kenya are reported to exceed those of western union globally. Whilst M-pesa presently vaunts large user adoption numbers, it is the first of its kind in the region to amass such achievement. Further, historically: products and services of similar nature to M-pesa have been unsustainable. A case of M-pesa's demise would have dire implication for the Kenyan economy and 30% of the households in the country that rely on it for remittances. To understand this phenomenon, extant studies have examined the drivers of adoption of this service but have slacked in subsequent investigations to understand user continuance with the service. As such, the information systems literature cautions that initial adoption of technology, although crucial, does not guarantee sustained use. Therefore it is imperative to investigate drivers of continuance. In general, extant research has not focused on investigations of user continuance intention in Africa. In response, this thesis presents an African based study on the determinants of user continuance intention towards M-pesa. Specifically, the purpose of this study was to i) identify and discuss factors from the literature that are most likely to influence user continuance intention towards M-pesa, (ii) develop a research model that is grounded in theory, (iii) test the model within the sample context to identify the antecedents and determinants of user continuance intention towards M-pesa in Kenya. A broad, critical review of the relevant literature provided basis for hypothesized relationships between the identified factors. A formal survey of users of M-pesa in Kenya comprised the phase of data collection and resulted in a usable data set of (n=434). The data collected from the respondents within Kenya was relied upon to test the hypotheses. The survey instrument used to measure the study's constructs was developed via a process of literature review, expert pre-testing, pilot testing, and statistical validation. Partial Least Square and Artificial Neural Network analyses were used to examine the study's measurement and structural model comprising variables of : behavioural beliefs (post-usage usefulness, confirmation, satisfaction), control-beliefs (utilization and flow), object-based beliefs (perceived task-technology fit, system quality, information quality, and service quality), and attitudinal belief (trust). Collectively, the afore-listed ten independent variables and one dependent variable (continuance intention) comprised the study's model. Four of the independent variables (utilization, satisfaction, flow, and trust) were hypothesized to directly determine continuance intention. Of these four, all emerged as determinants of continuance intention. However, trust emerged as the strongest determinant, subsequently, utilization, flow, and satisfaction respectively. The result was unexpected, as satisfaction (a behavioural belief) has been presented in the extant literature as the dominant determinant of continuance intention but does not hold a consistent predictive strength in a developing world. Its predictive power was diluted by trust, utilization, and flow amongst the Kenyan sample. The study's model revealed an R² of 0.334. The analyses demonstrated that user continuance intention is determined by factors across object, control, attitudinal, and behavioural beliefs. The unexpected finding of the rankings of predictive strength of the factors turns a new leaf and introduces areas of further inquiry in future studies. The study concludes with realized contributions to theory and important guidelines for current and future technology-enabled service vendors in developing regions.

The importance of collecting process data describing school counselor practice is widely supported as a component of accountability. However, the lack of practically significant and valid instruments may hamper this practice. The School Counselor Activity Rating Scale was designed to measure how school counselors actually spend their time versus how they would prefer to spend their time in job-related activities. Its development, initial validity and reliability results, and potential applications are presented in this article.

The purpose of this study was to examine the relationships between perceived organizational support, perceived coworker support, and debriefing on the one hand, and compassion satisfaction, burnout, and secondary traumatic stress on the other hand in Florida law enforcement, fire, emergency medical services, and dispatch public safety workers. In order to explore the relationships between these constructs, the research questions examined the relationships of the work environment of Florida public safety by administering surveys gauging perceived organizational support, perceived coworker support, psychological resilience, and debriefing activities that the personnel participate in. The Professional Quality of Life: Compassion Satisfaction and Compassion Fatigue Version 5 was also sent out to establish the self-reported levels of compassion satisfaction, burnout, and secondary traumatic stress. The study found that there were differences in the levels of compassion satisfaction, burnout, and secondary traumatic stress between the public safety fields. It also found that there was a positive relationship between the presence of perceived organizational support, perceived coworker support, psychological resilience, and debriefing activities on at least one of the constructs of compassion satisfaction, burnout, or secondary traumatic stress within the different public safety fields. This study furthers the literature by being the first study to compare the four different public safety fields in the state of Florida and with regards to those constructs.

The implications of rising healthcare expenditures are of great concern nationally and internationally. Performing procedures in the outpatient setting can be one solution to this crisis. However, there is a lack of research on systematic approaches for transitioning procedures to the outpatient setting. Unicondylar knee arthroplasty (UKA) presents an opportunity, as it is already in the early stages of transitioning to the outpatient setting. The key step in facilitating an effective transition to the outpatient setting is comparing outpatient UKAs with inpatient UKAs with a focus on process time, quality outcomes, and patient satisfaction. This study retrospectively compares 400 UKA patients in the outpatient setting with 675 UKA patients in the inpatient setting. The primary analytical tools for this study are Ordinary Least Squares Regression, Logistic Regression, and Ordinal Regression adjusting for comorbidity, social history, demographics, and surgery related characteristics. Outpatient UKAs outperformed inpatient UKAs across 11 of 18 variables analyzed. Process Time will be less for outpatient UKAs in all phases with the exception of Surgery Breakdown Time. The risk-adjusted quality outcomes of UKAs in the outpatient setting were better across Non-Surgery Related Complications, Follow-Up Pain, and Follow-Up Functional Range of Motion Limitation. Patient Satisfaction was higher for outpatient UKAs. There was a lack of consistent and appropriate information to conduct a substantial statistical analysis of the costs. These findings point towards outpatient UKAs being a viable option in the future. This research serves as a platform to launch a system-wide effort of transitioning procedures to the outpatient setting across different specialties.
