    Value co-creation through digital technology in developing economies : reflections from Indonesian agri-food E-commerce chain

    Full text link
    PhD ThesisValue co-creation (VCC) has supported the expansion of research in marketing by embracing service innovation within the digital-driven era. However, a small number of studies provide a comprehensive examination of VCC through digital technology from the perspective of multiple local market actors at developing economies at the bottom of the pyramid (BOP) market. This research explores the role of digital commerce in VCC with the empirical focus on the Indonesian horticulture industry, moving towards e-commerce for marketing innovation. This research aims to: (1) explore VCC manifestation within the local BOP market, (2) discover the role of e-commerce in the exchange process of co-creation at the local BOP market, (3) explore the dimensions of VCC of engagement amongst the local e-commerce supply chain actors of BOP, and (4) investigate the causes and effects of customer engagement to VCC of using e-commerce in this marketplace. This research adopted a mixed-method approach of qualitative semi-structured interviews and a quantitative survey. VCC identified as occurring in a newly emerging e-commerce marketing channel via the interaction amongst channel members. Inclusive, collaborative, and empowerment ideology contribute to market scripting scenario by local entrepreneurs who identify as ‘socio-entrepreneurs’. This research argues that the exchange logic underpinning this new transformative business approach of digitally enabled VCC in local BOP markets is akin to a ‘social justice logic’. For consumers, digital technologies create online ‘consumption communities’ where information is exchanged concerning product provenance and food preparation opportunities supporting online purchases and innovation in value chain ‘pull’ strategies. The research indicates that customer VCC behaviour was influenced by the significant effects of customer-related VCC resources of social expertise and openness, customer motivation, and its effects on value-in-use, willingness-to-engage, positive emotions, and behavioural intentions. Finally, the results highlight the moderating role of customer age and the length of engagement in VCC processes on these relationships.Indonesia Endowment Fund for Education (LPDP

    Realistic evacuation simulation through micro and macro scale agent-based modelling including demographics, agent patience and evacuation route capacities

    PhD ThesisDisasters affect millions of people annually, causing large social impacts, and detrimental economic impacts. Emergency professionals recurrently tackle these impacts, therefore they require assessment methods to understand potential consequences and enable the delivery of resilient resolutions. One method of achieving this is through numerical modelling, specifically agent-based modelling. However, current models simulating human behaviours and movement are bespoke in nature and non-transferable. It has also been found that current modelling tools have either focused on the microscale (e.g. individual confined spaces) or macroscale (e.g. city scale), without considering how the two scales may be interlinked. Further to this, the inclusion of human behaviour has been over-simplified and generic, lacking the inclusion of unique populations with varied characteristics. The aim of this research is to develop a modelling framework, utilising agent-based modelling, to form a more robust representation of human behaviour within an enhanced evacuation model environment. This will allow emergency planners to be better prepared, reduce the interruption after an event (thereby reducing social and economic impacts) and potentially reduce the mitigation required beforehand. The individual agents within the framework capture a range of robust human behaviour indicators (e.g. walking speed, obedience, and patience), allowing the accurate replication of an emergence scenario response. Initially, the research focused on creating a macroscale evacuation model for a test city, to assess whether the inclusion of varied population characteristics and groups of people affected evacuation time. The varied characteristics included a range of ages, gender, and mobility in the form of walking speed. It was then possible to compare this with the parameters of existing evacuation models. This research has found that by enhancing the representation of human behaviour within a model environment more accurate predictions of evacuation time can be produced. To produce more robust human behaviour, models must include a range of population characteristics (such as age, gender and mobility), the grouping of agents and walking speed ratio. When all the variables are included in the model, there is an average increase of 70% in the time to evacuate Newcastle city centre. Even with less variables, i.e. only considering population characteristics, there has been an average increase of 45% in the time to evacuate Newcastle city centre compared with existing models. To further examine human behaviour and the more intricate and detailed behaviours such as patience, a microscale model was created to consider the capacity of the pathways and to introduce congestion. The two microscale models were created of a pavement and a crossroads, ii to replicate people passing and waiting behind slower people, whilst still including the varied population characteristics. When capacity is captured at the microscale, there is an average 61% increase in the time to exit the pavement and when on a crossroads there is an average 87% increase in the time to exit compared to 1.34m/s (3mph) models. Overall, this research has found that there is a need to provide more robust representation of human behaviour characteristics within evacuation models. This must be carried out not only at the macroscale in terms of enhancing population demographics but also at the microscale by capturing intricate behaviours such as taking over and giving way. Without an ability to exhibit these characteristics evacuation simulations cannot effectively capture human behaviour and therefore produce robust simulation times. The inclusion of more representative human behaviour in simulations and the continual need to improve provides the opportunity to reduce the likelihood of increased fatalities and injuries caused by those unable to evacuate in time due to current underestimations. The improvement of computational simulation of evacuations alongside existing simulation techniques allows emergency professionals to plan and prepare better for a range of events to protect global communities

    Investigating Problem-Orientated Patient Pathways, Toothache to Treatment: ImPacT Study

    Full text link
    Ph. D. ThesisAlmost one-third of adults will only seek professional dental care when suffering with acute dental pain rather than engaging in routine preventive dental care, so called problem-orientated dental attenders. These individuals can wait a long time before seeking care resulting in: greater impacts on everyday activities, and greater potential for serious adverse events. They can present to a range of services including emergency dental services, medical emergency departments, and general medical practitioners (GMPs). The reasons for this attendance pattern and care pathway are under-researched. To encourage these patients to engage in routine dental care it is important to build an understanding of: (1) why they only attend when symptomatic, (2) where they present and why. The aim of this thesis was to build an understanding of problem-orientated attendance to subsequently develop an intervention to encourage regular dental attendance. This thesis involved four studies. The first was a retrospective observational study examining dental attendances at Welsh GMPs. The second and third were qualitative studies exploring: (1) problem-orientated attenders’ perspectives and experiences of seeking repeated emergency dental care (2) adolescents’ experiences of dental care and their future plans for dental attendance. The final study co-designed an intervention to prevent problem-orientated dental attendance. Dental attendance rates at GMPs varied over the study period and appeared to relate to key policy change dates. Predictors of being a repeat dental attender included deprivation, residential area, and appointment outcome. Reasons for problemorientated attendance were complex and multifactorial, with overarching reasons related to knowledge and dentist characteristics. Adolescents faced multiple barriers to dental care-seeking as they transitioned to independence subsequently affecting decision-making to continue to seek regular care. Finally, an intervention was developed targeted at adolescents and young adults to encourage continued regular dental attendance as they transitioned to independence, hence preventing problemorientated attendance.National Institute for Health Research (NIHR), European Society of Endodontolog

    A holistic study of the sustained impact of non-standard refined diesel fuel on the Niger Delta Region of Nigeria

    Ph. D. ThesisThe non-standard refining of crude oil in the creeks of the Niger Delta Region of Nigeria has come to be a profitable business. The monetary benefits this brings to the refiners are obvious, nevertheless the host communities are relentlessly hit by their activities. This research investigates the sustained impact of the activities of the non-standard crude oil refiners on their host communities. The research will take a social study approach, with result from the social study fed into a scientific study, which will in turn be fed into an engineering study. This approach involves all stakeholders and makes for necessary feedback. The results revealed that farming areas and fishing routes have been impacted by the activities of the non-standard refiners. The usage of the non-standard refined diesel fuel oil was found to be damaging to engines contributing to huge expense in their maintenance. The physiochemical properties of the non-standard refined diesel fuel oil revealed that the pour point, flash point, and water content showed differences to ASTM designated standard D975. The Gas Chromatography Mass Spectrometry (GC-MS) analysis revealed significant differences in the BTX concentration of the non-standard refined diesel fuel oils as compared to the control sample. The engine performance and emission analysis revealed high levels of oxides of nitrogen (NOx) and carbon monoxide emissions from the non-standard refined diesel fuel oil coupled with high peak cylinder pressure. This study provides evidence-based recommendations that the government should do more to discourage the citizens from establishing non-standard refineries. It also suggests that government agencies like the military given the responsibility of destroying the non-standard refineries must do so in a sustainable manner. The National Orientation Agency must do more to enlighten the public on the dangers of establishing non-standard refineries and purchasing refined products from non-standard refineries.Niger Delta University, Linkages and Advancements and the Tertiary Education Trust Fund (TETFund

    Integrated topological representation of multi-scale utility resource networks

    Full text link
    PhD ThesisThe growth of urban areas and their resource consumption presents a significant global challenge. Existing utility resource supply systems are unresponsive, unreliable and costly. There is a need to improve the configuration and management of the infrastructure networks that carry these resources from source to consumer and this is best performed through analysis of multi-scale, integrated digital representations. However, the real-world networks are represented across different datasets that are underpinned by different data standards, practices and assumptions, and are thus challenging to integrate. Existing integration methods focus predominantly on achieving maximum information retention through complex schema mappings and the development of new data standards, and there is strong emphasis on reconciling differences in geometries. However, network topology is of greatest importance for the analysis of utility networks and simulation of utility resource flows because it is a representation of functional connectivity, and the derivation of this topology does not require the preservation of full information detail. The most pressing challenge is asserting the connectivity between the datasets that each represent subnetworks of the entire end-to-end network system. This project presents an approach to integration that makes use of abstracted digital representations of electricity and water networks to infer inter-dataset network connectivity, exploring what can be achieved by exploiting commonalities between existing datasets and data standards to overcome their otherwise inhibiting disparities. The developed methods rely on the use of graph representations, heuristics and spatial inference, and the results are assessed using surveying techniques and statistical analysis of uncertainties. An algorithm developed for water networks was able to correctly infer a building connection that was absent from source datasets. The thesis concludes that several of the key use cases for integrated topological representation of utility networks are partially satisfied through the methods presented, but that some differences in data standardisation and best practice in the GIS and BIM domains prevent full automation. The common and unique identification of real-world objects, agreement on a shared concept vocabulary for the built environment, more accurate positioning of distribution assets, consistent use of (and improved best practice for) georeferencing of BIM models and a standardised numerical expression of data uncertainties are identified as points of development.Engineering and Physical Sciences Research Council Ordnance Surve

    The motivations and outcomes of consumer engagement with online sexual health communities

    Full text link
    PhD ThesisThe continuous improvement in living standards has resulted in increasing attention being paid to personal health. The definition of health nowadays no longer refers only to physical or mental health, it also includes sexual health. Sexual health is not only understood in a narrow sense as Sexually Transmitted Diseases (hereafter STDs), but also the enjoyment and satisfaction of having sex with partners. Positive sexual experiences are beneficial to both physical and mental health (Hensel et al., 2016). Although, despite it being an important part of our lives, sometimes sexual health is difficult to discuss due to the stigmatization and discrimination associated with STDs, which can affect patients’ intention to seek a doctor’s advice, leading those patients in need to ignore their illness for fear of unfair treatment which in turn can lead to serious physical outcomes and psychological burdens. The National Health Services (NHS) is under enormous pressure from an increasing demand for consultation; in 2020 more than 60 million people were listed as registered with the NHS (NHS Digital, 2020). This sometimes results in patients not being able to seek medical attention promptly or having only a short consultation time, which is sometimes not sufficient to properly address an individual’s health concerns, and more specifically their concerns about STDs. By gathering users from multiple backgrounds and experiences to form a virtual online community, Online Sexual Health Communities (OSHCs) provide a platform for information sharing and the exchange of emotions (relating to sexual health). Combining the advantages of a virtual environment such as unrestricted time and space, OSHCs not only provide a convenient and effective consultation with users who may have similar health issues but also reduce the pressure on the NHS (Nagendra et al., 2020). Despite the relevance of health communities in today’s societies, the reasons why consumers engage with OSHCs has rarely been studied, nor has the consequences of such engagement on consumers’ psychological and physical wellbeing. This study believes that learning about the motivations and outcomes of OSHC engagement is conducive to enriching the existing engagement literature in the field. From a practical point of view, it provides a more comprehensive guide for those establishing, or seeking to establish, OSHCs. Accordingly, a clear understanding of a user’s motivation for engaging with an OSHC iii can better help the founders of sexual health forums in improving their online communities. Furthermore, understanding the outcome of their engagement can help public organizations understand their influence on individuals’ wellbeing. Scholars are calling for qualitative research on the impact of social media on consumer behaviour and societal wellbeing (Davis et al., 2016; Shensa et al., 2017). The present study lies within transformative consumer research, which focuses on significant social issues and challenges (Davis and Ozanne, 2019). Interviews were chosen for data collection due to their ability to uncover underlying motivations, beliefs, attitudes, and feelings (Rubin and Rubin, 2005), particularly in discussions involving sensitive or embarrassing topics (for example, body image concerns and self-esteem) (Malhotra et al., 2007). The author of this thesis conducted semi-structured interviews with 20 participants from one of the most popular OSHCs on Facebook namely PrEp Facts: Rethinking HIV Prevention and Sex. Data were analysed through both manual coding and NVivo. Ten themes emerged from the interviews including eight motivations and two consequences of engagement, which enabled the development of a conceptual framework of engagement with OSHCs The contributions of this study can be viewed from both a theoretical and practical perspective. Theoretically, this study provides a conceptual framework regarding the motivations and consequences of consumer engagement. This study sheds light on eight motivations: information quality, information quantality, social support, fear, source credibility, convenience, online community quality, and privacy concerns. There are two outcomes of consumer engagement with OSHCs (health empowerment and entertainment), which contribute to the existing literature. Specifically, this study offers a comprehensive understanding regarding consumer engagement towards OSHCs, which can help online community moderators develop a better virtual environment based on consumer demands. Future research around this subject should use quantitative research methods to further verify the model developed in this study

    Crisis management, reinvention and resilience in museums : the Imperial War Museum during the Second World War Era, 1933-1950

    Full text link
    PhD ThesisThis thesis is about museums and crisis. Through research on the Imperial War Museum, known today as IWM, during the Second World War era, 1933-1950, it reveals how crises disrupt museums, and the contrasting defensive and revolutionary strategies which museums must adopt when mitigating crisis situations. The thesis is situated in a small but emergent literature concerning museums and crisis. Existing work comprises contemporary case studies on difficult museum experiences, predominantly financial difficulty, wherein crisis has been applied to describe an institution’s general state of organisational malaise. This thesis, by contrast, is innovative in that it comprises a historical case study on a museum facing wholesale physical and ideological collapse, and deploys newly developed crisis concepts to analyse different critical situations that can impact museums and to analyse the pathology underlying them. It draws on methodology informed by various case study, archival and historical theorists, and is produced using data extracted principally from documentary sources researched at the IWM museum archive and The National Archives. Through investigating the experience of the Imperial War Museum during the Second World War era, this thesis finds that museums can be harmed by two crisis types. The first comprises a surface-defensive crisis, where the impacted museum must rebut the crisis effects. This type was conceived through considering the impact of the wartime aerial attacks against London on the Imperial War Museum. The second type comprises a deep-revolutionary crisis, where the museum must transition from its existing crisis-ridden state to some new, more sustainable paradigm. This type was conceived through considering the threats posed by cultural irrelevancy, perceived during the war, against the Imperial War Museum after the conflict. Delivered via an original synthesis of historical, museological and crisis research, the outcome of these findings comprises a novel understanding of crisis in the museum context.Arts and Humanities Research Council, the Northern Bridge Doctoral Training Partnership and Newcastle University.

    Ph. D. Thesis.Reduced mains water consumption and renewable electricity generation in the built environment are key sustainability challenges for a rapidly urbanising global population. This dissertation assessed the performance of various technological and management solutions for saving mains water and generating solar electricity in the urban environment. Three student accommodation blocks and two Green Gown Award winning buildings of Newcastle University in the UK, and India’s first 5-star Green Rating for Integrated Habitat Assessment (GRIHA) campus provided unique case studies for the real-world performance assessment of sustainability solutions such as smart sensor systems, rainwater harvesting systems, wastewater reclamation systems, ultralow water use appliances, and photovoltaic panel systems. The related mains water and grid electricity savings, operational and repair costs and payback periods for capital expenditures were collated. Interviews with building managers provided insight into asset management challenges. Recurring themes from the case studies were the high costs of rainwater harvesting systems, and significant water savings opportunities via better management which were revealed by consumption monitoring. In the Indian case study, better water management to address leakage, and more drought-tolerant landscaping in a semi-arid climate, could reduce blue water use by up to 52% and reduce operational costs by up to 23%. In the UK student accommodation case study, up to 50% of potable water use was caused by malfunctioning toilets. In the UK mixed use building case study (office/teaching/laboratory), significant performance gaps of green building assets arose from technical and social issues (pump failures, leakages, poor alignment of demand and supply with limited storage, low photovoltaic panel efficiency, poor user acceptance, etc.), but the consequences were exacerbated by inadequate asset management that resulted in long system downtimes. Overall, it was concluded that better monitoring, maintenance, and management are the most cost-effective ways of improving water use sustainability in the built environmen

    Dysphagia in head and neck cancer patients in Kuwait

    Full text link
    PhD ThesisIntroduction: Head and Neck Cancer (HNC) and its treatment often result in severe functional impairments, with dysphagia and related morbidities being serious and wellrecognised complications in the acute, chronic and late stages. These complications contribute to a decreased quality of life and decreased overall HNC survival. An active surveillance of swallowing function using appropriate swallowing outcome measures is needed throughout the continuum of care. HNC dysphagia has not been studied previously in Kuwait. Aims: The overall aim of this thesis is to investigate HNC dysphagia in Kuwait, with a longterm view to improve quality of life and reduce morbidity. Methods and results: Five studies were conducted using different research designs. The first study aimed to investigate the prevalence of HNC dysphagia. The results suggest that dysphagia is not properly assessed and therefore may be under-reported. The second study explored the experiences and unmet needs of patients with HNC in Kuwait using qualitative interviews. The interviews revealed that patients often experience adverse feelings as a result of their functional and physical pain, and they employ different strategies to deal with their symptoms. Furthermore, the findings suggest that patients have substantial unmet informational and supportive care needs. Studies three to five aimed to further explore swallowing outcome measures in order to develop a multi-dimensional Swallowing Outcomes Package to systematically collect outcomes for HNC patients in Kuwait. The Package comprises: the MD Anderson Dysphagia Inventory (MDADI), a patient self-report tool, which was translated and culturally adapted and showed satisfactory psychometric properties. Diet scales, and a measure of swallowing performance (the 100mL Water Swallow Test (WST)). Preparatory work established the factor structure of the MDADI and the minimal clinically important difference for the 100mL WST. Conclusion: This study identified gaps in HNC dysphagia management in Kuwait, and it highlights the importance of the systematic collection of swallowing outcomes to understand the impact of cancer treatments, monitor changes over time, and improve quality of life and decrease morbidit

    An investigation of the driving factors affecting children’s water, sanitation and hygiene (WASH) behaviours in East New Delhi primary schools

    PhD ThesisSustainable Development Goal 6 (Clean Water and Sanitation) addresses gaps that persist in Water, Sanitation and Hygiene (WASH) access worldwide, particularly affecting poor communities’ opportunity to live healthy, hygienic lives. According to the ‘Capability, Opportunity, Motivation Behaviour Model’, these three domains must be addressed for WASH interventions to achieve sustained adoption of targeted behaviours. Numerous factors pertaining to these three domains enable or obstruct East New Delhi primary school children’s WASH behaviours and therefore progress towards SDG 6. This thesis investigates these driving factors, analysing mixed methods data gathered in three government schools and one low-fee private (LFP) school, as well as in the communities surrounding them. The main findings indicate that: - Children attending the LFP school practise positive WASH behaviours more frequently than government school children and have access to superior school WASH provision. Children at schools with higher-quality WASH facilities are more likely to practise positive WASH behaviours. - School principals face challenges in providing adequate school WASH facilities and ensuring that children have the capability, opportunity and motivation to practise positive WASH behaviours. These include insufficient funding, teachers’ obligatory non-school commitments, unexplained teacher absenteeism and a high turnover of students. Schools-based WASH interventions can mitigate these, particularly by motivating school staff. - Socio-economic status affects children’s opportunity to adopt positive WASH behaviours. Children from lower-income backgrounds practise positive WASH behaviours less often. Schools-based WASH interventions could mitigate this through outreach to parents and children transferring learning into the household. These findings reveal the driving factors affecting children’s capability, opportunity and motivation to practise positive WASH behaviours in East New Delhi primary schools. Secondly, they highlight action which could be taken to support children’s sustained adoption of these behaviours, securing progress towards SDG 6 for the next generatio
