Intangible Experiences Assignment
(Bangor University, 2024-04-01) Alalloia, Yasser; Jones, Edward
Meeting the growing demand of tourists for memorable experiences is a primary goal and a serious challenge for Dubai (Dubai Tourism, 2021). The city has utilised social media in tourism marketing and management successfully. For instance, during the #BeMyGuest campaign on YouTube, featuring Bollywood superstar, Shah Rukh Khan, Dubai used a unique and highly personalised storytelling approach to marketing the city as a tourist destination brand (Dubai Tourism, 2021). While these efforts may be considered a successful shift of the city to the customer-oriented approach to tourism marketing and management, not all companies could harness the tremendous branding potential. One recent study shows that word of mouth remains the primary approach of small and medium hotels to advertise their business and attract more clients (Ahmad & Saber, 2015). Apparently, they rely on personal investments to keep their companies afloat. They cannot afford such risky ventures as social media campaigns (Ahmad & Saber, 2015). Thus, the unaffordability of social media marketing may become a serious barrier to successfully utilising social network sites for marketing purposes.

Examining the Suitability, and Feasibility of a Nurse-led Foot Care Educational Intervention in Adult Patients with EndStage Kidney Disease Receiving Haemodialysis
(Queen's University Belfast (QUB), 2024-04-08) Alshammari, Layla Salem S; Noble, Helen; O'Halloran, Peter; Doherty, Julie; McSorley, Oonagh
People with end-stage kidney disease undergoing haemodialysis are at risk for peripheral arterial disease, lower limb amputation, and foot ulceration. Neuropathy and previous ulceration are the major risk factors for foot ulceration in patients undergoing dialysis. Similar risks apply to people with diabetes mellitus. Providing haemodialysis patients with education about foot care is crucial because it can help improve patients’ foot care knowledge, foot self-care behaviour, and prevent or minimize the incidence of foot ulcer development and amputation of the lower limb. Haemodialysis nurses are well-placed to provide information, education, and support for patients with end-stage kidney disease receiving haemodialysis in the dialysis unit. However, there are no studies of nurse-led foot care educational intervention programs for end-stage kidney disease patients receiving haemodialysis, despite the fact that patients with end-stage kidney disease have prevalence rates of risk factors similar to those in patients with diabetes mellitus. Therefore, there is a need for a nurse-led foot care educational intervention that can feasibly be delivered by haemodialysis nurses to patients with end-stage kidney disease receiving dialysis. Aim and objectives: The present study aimed to develop a nurse-led foot care educational intervention programme and explore its feasibility for use with patients who have end-stage kidney disease treated with haemodialysis. There were three phases to the study, with each phase having its own objectives. Phase 1: Developing a nurse-led foot care educational intervention programme: The nurse-led foot care educational intervention programme was informed by: a) a systematic review, which was undertaken to examine the factors that help or hinder the successful implementation of foot care educational programmes for patients with end-stage kidney disease receiving haemodialysis; b) an umbrella review, which was undertaken to derive further evidence from existing systematic reviews and meta-analysis of the effectiveness of interventions directly aimed at diabetes patients; c) an interdisciplinary advisory group made up of key stakeholders; and d) foot care education guidelines (National Institute for Clinical Excellence (NICE, 2019), the Registered Nurses Association of Ontario (RNAO, 2013), and the International Working Group on the Diabetic Foot (IWGDF, 2019)). Phase 2: Implementation of the foot care educational intervention programme: Early testing of programme theory and evaluation of the feasibility of measurement tools through a one-group pretest-posttest design with haemodialysis nurses, haemodialysis patients and their informal caregivers was carried out. The evaluation also involved measuring the foot care knowledge of haemodialysis nurses, foot care knowledge, and foot self-care behaviours of haemodialysis patients as well as the foot care knowledge of informal caregivers. Phase 3: Process evaluation: A qualitative exploration of factors affecting the acceptability of the intervention with key stakeholders (haemodialysis nurses, haemodialysis patients and their informal caregivers) following the implementation of the intervention programme. Conclusion: A nurse-led foot care educational intervention programme for patients with end-stage kidney disease receiving haemodialysis is highly acceptable for haemodialysis nurses, haemodialysis patients, and their informal caregivers, and a definitive trial is feasible with small modifications such as adding a foot assessment form during the future implementation and evaluation of randomised controlled trials. The researcher and the advisory group will search for a valid and reliable form for a foot assessment form. If one is not available, the researcher and advisory group will develop it. Foot-care assessment is important, as previous research indicates that regular foot assessments, education, suitable footwear, and timely referral for care escalation can effectively prevent foot problems.

Definite and indefinite affixes in Tihami Arabic
(The University of Kansas, 2024-04-09) Asiri, Amer; Gluckman, John
This dissertation explores the semantics of definite and indefinite affixes in Tihami Arabic. The dialect exhibits a four-way distinction in its (in)definiteness paradigm, which makes it a good example to investigate (in)definiteness theories. The dialect exhibits two ways to inflect indefinite nouns: with -in and with the bare form. Additionally, the dialect has two ways of inflecting definite nouns: with -im and al-. I argue that the bare forms of nouns are true indefinites and -in is a “situation-associated” morpheme that quantifies over the topic situation. Moreover, I argue that the two types of definites in Tihami are best captured by appealing to L¨obner’s (1985, 2011) uniqueness distinction which claims that elements are either inherently unique or inherently non-unique. Concerning the indefinite markers, while the bare form of the noun is a true indefinite, the seemingly indefinite marker -in distributes on domains beyond nouns such as predicate domain and on dislocated elements, and it correlates with different interpretations such as specificity, stage-level, and discourse prominence readings. I show that the primary trigger for the -in’s occurrence is the availability of a context. Using situation semantics, I argue that -in’s function is to associate the element it marks or the whole utterance to the topic situation. The implementation of this analysis extends to the realization of the morpheme -in in other Arabic varieties and possibly justifies their distributions. I further argue that the two types of definite markers in Tihami are semantically determined. Their distribution is contingent on whether the uniqueness is inherent or derived from the context. While al- occurs on elements that are inherently unique, im- derives its uniqueness from the context and occurs with elements that are inherently not unique. Following ˇSim´ık (2018), I utilize situation semantics and modal semantics to account for the two types of definite markers; I argue that al- is evaluated with respect to all situations that are similar to the topic situation, whereas the uniqueness of im- is only evaluated relative to the topic situation. I also discuss cases where the uniqueness of inherently unique entities is altered to be derived from the context. The definite and indefinite markers correlate with each other. While the definite im- correlates with -in in that they are both contextually determined, al- correlates with the bare form of the nouns in their ability to express genericity. Besides their possible similar form, I argue that the correlation between im- and -in is due to their quantification over the topic situation; by contrast, the source of correlation between al- and the bare forms is due to their non-situational restriction. The correlation spans from the form to the meaning, implying a partially unified analysis. This dissertation provides a deeper understanding of theories of definiteness and indefiniteness. It also deepens our understanding of the behavior of (in)definiteness of other varieties of Arabic, and possibly other Semitic languages.

Independent Mobile Learning of English: The Case of Saudi Female University Students
(University of Leeds, 2024-03-05) Basheikh, Amal; Walker, Aisha
This thesis investigates the use of smartphones for independent language learning, focusing on the experiences of seven female university students in Saudi Arabia. It aims to understand how they use their smartphones for language learning and to identify the challenges they face. This was implemented through my proposed Independent Mobile Learning of English (IMLE) framework: This framework encompasses three phases: 1) planning; 2) management of learning activities; and 3) monitoring and evaluating learning processes and outcomes. This study employs a qualitative approach, where data were gathered from seven participants through semi-structured interviews. To enrich the dataset, additional media materials, such as screenshots and video clips illustrating their smartphone usage for language learning, were also gathered. MAXQDA software was used to analyse the data. Six key themes were identified to understand the IMLE experience across the three phases of the framework. Within the first two phases, planning and management of learning activities, there were four themes. First, learners incorporated English into their daily routines using various tools, such as social networking sites and films. Second, they identified the importance of choice in deciding on language partners for conversational practice across different social digital tools. Third, learners used a range of digital platform serving different needs. Fourth, they used translation tools to enhance their language competence and confidence. From the final phase of the IMLE framework, two themes emerged, which dealt with monitoring and evaluating learning outcomes as learners acknowledged challenges and reflected on solutions. First, learners recognised the importance of following their own interests in IMLE. Second, they reported the need for community support to make IMLE more effective. The findings of this study provide insights that will be valuable for educators and researchers who aim to create effective language-learning experiences tailored to learners’ needs in an increasingly digital world, as well as for learners interested in engaging in IMLE.

Modelling and Forecasting Volatility of Bitcoin Cryptocurrency: A Comparative Study of Conditional Heteroscedastic Model
(Queen Mary University of London, 2024-03-27) Alsulami, Amal M Saeed; Koutroumpis, Panagiotis
This study details three cryptocurrencies: Bitcoin, Ethereum, and Tether. These cryptocurrencies provide a high return but also pose a high degree of risk to investors. The changes in the prices of the currencies impact their return volatility. This report presents the performance of two models employed in forecasting the volatility in the times series data. These models are the ARCH and GARCH. The research presented in this report employs a GARCH suite of models: ARCH (1), GARCH (1,1), as well as GARCH-M and PARCH. The three models are described based on the literature review and their roles. Using the data collected based on these models, prices, and changes in investments are determined. A methodology based on the models was applied to test the data and measure the stationarity and structural breakpoints and the ARCH effects. From the collected data and methods employed to evaluate it, this study concludes that the ARCH (1) model has the best performance for all three cryptocurrencies when it comes to return and risk.
