Location-based service (LBS) is a geographical location-related service that provides highly personalized services for users. It is a platform for network operators to provide new and innovative ways of increasing profits from new services. With the rapidly growing trend toward LBS, there is a need for standard LBS protocols. This thesis started with introducing the Internet Engineering Task Force GEOPRIV working group, which endeavors to provide standard LBS protocols capable of transferring geographic location information for diverse location-aware applications. Through careful observation, it was found that Session Initiation Protocol (SIP) is well suited to the GEOPRIV requirements. The aim of this research was therefore to explore the possibility of the integration of LBS and the SIP protocol and, to some extent fulfill the GEOPRIV requirements.

Objectives: Systematic review: This article presents a systematic review of studies evaluating the evidence for mobile phone-based interventions with adolescents who have Type 1diabetes. Studies were critically appraised and findings synthesised with the aim of answering the question: do mobile phone technologies facilitate improved outcomes in adolescents who have Type 1diabetes? Empirical research study: Diabetes research has indicated an association between attachment security and metabolic control as well as increased prevalence of mental health difficulties in diabetes populations. There is limited research with an adolescent Type 1 diabetes population. The current study aimed to examine attachment, emotional distress and self-esteem in an adolescent Type 1 diabetes population in relation to metabolic control and quality of life. The current study also aimed to evaluate the impact of ‘wellbeing text-messaging support’ with the same population. Method: Systematic review: A systematic search strategy was employed to identify relevant studies. An electronic database search, combined with a hand search of key journals and reference sections of key papers, was undertaken. Methodological quality was determined using an idiosyncratic measure including information relating to study design, sample size, interventions and statistical analyses. A narrative synthesis was performed due to the heterogeneity of the sample. Empirical research study: 60 participants aged between 12-18 years old who had a diagnosis of Type 1 diabetes for over 12 months took part. A longitudinal questionnaire design was used to collect data using five validated psychological measures. HbA1c was used as a measure of metabolic control. Text-messaging comprised a wellbeing module delivered daily over a three-week period. Results: Systematic review: 12 eligible studies were identified. One achieved a rating of ‘very good’, two a rating of ‘good’ and the remaining nine were pilot and/or feasibility studies, of whom four received a rating of ‘fair’ and ‘five received a rating of ‘poor’ methodological quality. Results indicated limited good quality evidence which included improved adherence and self-efficacy and mixed results in relation to metabolic control. Limitations identified included the use of small, convenience samples and short study duration. Empirical research study: High levels of fearful attachment security predicted poorer metabolic control and poorer quality of life, and high levels of emotional distress predicted poorer quality of life. ‘Wellbeing text-messaging support’ resulted in significantly improved quality of life. Conclusion: Systematic review: There is limited evidence that mobile phone technology has consistently improved outcomes in adolescents with Type 1 diabetes. Due to the number of pilot or feasibility studies and predominantly poor/fair quality of the current literature, and the heterogeneity of the sample, only tentative conclusions can be drawn, thus highlighting the need for further research. Empirical research study: Adolescent attachment style and emotional distress may be assessed as part of routine diabetes care in order to identify individuals who are potentially most at risk of failing to engage with diabetes health care. This can subsequently impact negatively on metabolic control and/or quality of life. These findings highlight the importance of clinical psychology input in paediatric diabetes teams. Further research in relation to text-messaging support was recommended.

This thesis looks beyond the sensationalized coverage of Islamic State and instead utilizes Islamic State materials as a window into the remote radicalization and recruitment process of susceptible English-speaking individuals in the West. This thesis considers Islamic State’s mode of operation in conjunction with the appeals made in its online materials to devise a framework for understanding how Islamic State materials interact with susceptible individuals. The framework lends insight into how the body tasked with creating counter-narratives within the U.S. State Department can more effectively disrupt the remote recruitment and radicalization process.

The introduction of the Internet and computers into the work environment have changed the news industry. New models of revenues for spreading the news, and the reachability and accessibility of the news has grown tremendously. These implications have influenced the way media company’s employees have to work, from multi-skilling to communicating with each other efficiently. This research seeks to investigate the current state of the internal communication flow in a Swedish media company called Hallpressen AB and to find opportunities for improving the internal communication flow inside the company. In order to fully understand the existing situation in the company, the authors observed nine of the company’s departments, held 14 interviews with managers and executive committee members, and conducted two focus groups. Based on the data collection, the authors created a communication channel model of the existing communication inside the media company, and performed a qualitative content analysis to summarize the findings from the observations and interviews. The focus groups were performed in order to examine an existing communication tool called “Slack”, and to understand the general perception that the company’s employees held of it. From the findings, the authors suggested possible improvements for the company’s internal communication flows. First, what could be improved in the management of communication inside the company, such as opening of a communication department or hiring an internal communicator. Second, what could be improved in already existing communication channels, such as creation of special part on the intranet for every department and etc.

Despite the distance that often separates grandparents from their young adult grandchildren, the abundance of new technologies provides numerous means of connection for the grandparent-grandchild (GP-GC) dyad. The purpose of this study was to understand how grandparents use technology, namely text messaging and Facebook, in relationships with their young adult grandchildren. Specifically, the aim was to understand grandparents' purposes for using these technologies with their grandchildren, their motivations for using these technologies, and their perceptions of these technologies. Qualitative interviews were conducted with 23 grandparent participants and analyzed according to the procedures delineated in grounded theory analysis. Both text messaging and Facebook emerged as important tools for connection, as text messaging encourages more frequent communication and Facebook helps grandparents "fill in the gaps" about their grandchildren's lives. Furthermore, results indicated that grandparents' uses of text messaging, and to a lesser extent Facebook, are acts of accommodation to their grandchildren.

This research examines the role of electronic messaging in business firms.

The research focus is intermediate-size firms.

Obesity ascending rates are still a public health priority. The primary aim of the study was to evaluate the effect of tailored text messages on body weight change in overweight and obese adults in a community based weight management program. A secondary aim was to detect behavioral changes in the same population. The study design was quasi-experimental with pre and posttest analysis, conducted over 12 weeks. A total of 28 participants were included in the analysis. Body weight, eating behaviors, exercise and nutrition self-efficacy, attitude toward mobile technology, social support and physical activity were assessed at baseline and at 12 weeks. Text messages were sent biweekly to the intervention but not to the control group. At 12 weeks, the intervention group had lost significant weight as compared to the control group. There was a trend toward an improvement in eating behaviors, exercise and nutrition self-efficacy in the intervention group, with no significant difference between groups. A total of 79% of participants stated that text messages helped in adopting healthy behaviors. Tailored text messages appear to enhance weight loss in a weight management program at a community setting. Large scale and long term intervention studies are needed to confirm these findings.

Doctor of Philosophy / Department of Hospitality Management and Dietetics / Carol W. Shanklin / This study used two operational research components to explore strategies to decrease waste in university dining facilities. Component one assessed students’ beliefs and behaviors toward food waste in a selected dining center. The relationships between students’ food waste behavior, sustainability beliefs, and demographics were evaluated with the use of a self-administered survey and continual food waste monitoring. This study also assessed whether simple prompt-type message interventions had an impact or if the addition of more personally relevant feedback-based data elicited a greater change in consumer beliefs and behaviors On average, more than 57 grams of edible food was left on each tray. Food waste behaviors were not influenced by demographic factors. Individuals with higher levels of food waste beliefs also disposed of less edible food items. The simple prompt-type messages stimulated a 15% reduction in food waste. The addition of more personalized feedback-based messages did not stimulate a change above that of the prompt message. These findings indicate that simply making university students aware of the topic of food waste may be useful in improving their behaviors. Component two evaluated the operational feasibility of implementing tray free dining at Kansas State University Dining Services. Telephone interviews with managers of university dining facilities involved in tray free dining were conducted to identify best practices. Focus groups of students were used with a written survey to gain insight into their perceptions of tray free dining. Benefits included: decreased waste, reduced chemical, resource, and food costs, and improved student satisfaction. Managers identified complaints and dining room cleanliness as negative outcomes. Student involvement, education, and communication were strongly recommended by both managers and students. This research supports the recommendation to consider the implementation of tray free dining at Van Zile. Decreased costs, improved satisfaction, and positive public perception are likely positive outcomes.

The purpose of this study was to investigate whether learners from different primary schools would respond to cell phone SMS (short message service) questions related to their schoolwork after school hours. As young people use cell phone technology to socialise, it seemed appropriate to consider integrating this technology within the school-framework, as many schools do not allow the use of cell phones during school. Another aim was to find out whether socio-economic backgrounds or gender groups responded differently to the SMS interaction study. A concurrent triangulation design research method was applied. The study examined how often and what types of answers learners would submit via SMS after school hours. The principal conclusion was that the learners reacted positively to the SMS feedback response sent in reply to an SMS answer and then engaged to a greater degree with the further questions.

Despite efforts to mitigate texting and driving in the United States, accidents as a result of distracted driving continue to increase, especially within the 16-24 age group. Considering the traits of the members of this age group, as well as the attributes of the various means that are utilized to mitigate such behavior, I hypothesize that the employment of filmed narratives in public service announcements is more effective than any other established approach. Testing the validity of this hypothesis, contributing to a lack of research, three methods of analysis were employed in this project: a textual analysis of a filmed narrative; an audience analysis of the comments accompanying the filmed narrative; and a video session followed by a self-administered questionnaire. The results of this study indicate that while the filmed narrative is more effective than the spoken narrative, more intensive analyses are necessary for further speculation. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection
