    • The social, legal, and technical perspectives of cyberstalking in India

      Miftha, Ameema (University of BedfordshireUniversity of Bedfordshire, 2024-02)
      Cyberstalking is a consequence of the worldwide growth in the use of internet-enabled information and communication technology (ICT) services and devices, especially the indiscriminate and unhindered use of the products and services of social media sites, channels, and apps. This cybercrime has had a severe impact on the psychological and physiological states of millions of innocent victims and is a major social and legal concern. Society is still discovering ways to effectively address cyberstalking, especially in countries such as India, where IT-based technologies and services are comparatively better developed due to the country’s strong talent pool and expertise. This study explores the social, technical, and legal perspectives on cyberstalking in India. Although cyberstalking is a global phenomenon, in the Indian context it has received limited attention in both academic and social research fields. From the Indian perspective, the research gaps result from poor sociocultural perception, perpetual ignorance, and cultural conflict among the victims and their family members; poor perception, inadequate legislation, and late reaction from the legal authorities; and technological limitations to identifying perpetrators. The objectives of this research were to examine Indian victims’ perceptions of cyberstalking in their prevailing socio-cultural setting; examine the impacts of cyberstalking; understand the perceptions of legal enforcement authorities and identify inadequacies of the Indian legal system; understand the role of technology in preventing cyberstalking; draw a comparison between India, the United States, and the UK; and suggest improvement measures. Following a grounded theory synthesis, this study used a victim questionnaire, individual victim’s testimonials, and thematic expert interviews as the primary data collection tools together with an exploratory literature review to achieve the research objectives and answer the research questions. An extensive review of the literature on the subject was conducted to analyse and identify gaps in the research to formulate the research questions according to the objectives of the study and to frame the research strategy with tools. Accordingly, a Likert scale survey, which had 260 samples associated with cyberstalking, was conducted to understand the following: the social media environment and cases of cyberstalking, the victims’ perceptions based on their experiences in the online environment, the victims’ experiences of dealing with the police and the legal system, the responses, and attitudes of the victims’ families while they were pursuing their cases, and the outcomes. The research also delved into specific cases of cyberstalking to understand the genesis, development, and outcomes of such incidents. To further understand the causative factors and dynamics of cyberstalking and its outcomes, an expert opinion was sought from select experts from the technological, social, and police/legal justice systems. The analysis included quantitative analysis of the survey data with statistical tools such as percentage analysis, comparative analysis, and correlation coefficient analysis using statistical package for the social sciences (SPSS) software to gather insights about the internet and the social media environment. Next, the perceptions of victims gathered via the Likert scale method were analysed using content analysis and comparative analysis techniques. The third stage included an analysis of expert inputs using thematic analysis and content analysis backed by software-based output using NVivo software. From the sociocultural perspective, the accumulated findings from the literature review, victim surveys, victim case studies, thematic analyses of interviews with experts and victims, and semiotic analyses of victim case studies suggested issues and concerns, primarily secondary victimisation from family and friends. The primary study results pertaining to the case testimonials and the thematic interviews suggest that secondary victimisation by family members’ and relatives’ reactions to cyberstalking are determined by the social and cultural responses that may happen if such incidents occur in the real world. In Indian society and culture, family prestige and standing have more value than an individual’s choice or preference. The family, extended family, and social environment are integral parts of life. However, in most cases of cyberstalking, the support system does not provide the required support, as there is a gap in the parents’ and family support groups’ understanding of the context of the cyberstalking. In India, the flawed sociocultural mindset and inadequate legislation often result in secondary victimisation. Factors such as poor social and cultural perceptions of the victims and their family/relatives, general and cultural ignorance, and false family prestige permeate the crime and its implications for victims’ psychological and physiological states. Cyberstalking can even result in victims being punished and harassed further by family members. As a result, the number of formal legal complaints and cases remains low compared to the actual number of incidents. Often, the cyberstalking incidents change victims’ lives permanently. The impact on victims is particularly severe due to secondary victimisation. As per the findings from the legal and technical perspectives, factors such as poor social perception of the crime, cultural conflict and ignorance, the subjective characteristics and habits of the victims, the freedom and remoteness of internet technology, and the inadequacy of cyber-legislation to preventing and to penalise cyberstalking have all facilitated the proliferation of cyberstalking in India. Hence, from the Indian perspective, the research gaps are threefold: social, legal, and technical. From a social perspective, the factors are general lack of understanding, cultural conflict, and perceptual ignorance on the parts of the victims and their family members. From a legal perspective, compared to developed countries like the United States and the UK, the law is inadequate to prevent cyberstalking, and from a technical perspective, technology plays the dual role of facilitator and preventer of cyberstalking. This study validates the findings, and recommendations based on Stamper’s semiotic framework are given. In addition, a framework for regulating cyberstalking across the six layers of the semiotic framework is suggested.
    • The mediating role of thriving at work between organizational inducements and work outcomes

      Karadas, Georgiana; Vatankhah, Sanaz; Ozturk, Anastasia; Altun, Ozlem (Wiley, 2023-11-20)
      The study intends to assess the underlying mechanism of thriving between organizational inducements (OIs) and health care workers’ (HCWs) mental health and work effort based on social exchange theory and the socially embedded model (SEM) of thriving. This study tested a conceptual model regarding the antecedents and outcomes of thriving at work (TW). According to the results of structural equation modelling, both dimensions of OIs predict TW among HCWs. Employees who receive OIs display enhanced levels of thriving, which plays a key role in HCWs’ mental health and their work effort. This research adds important insights to the thriving literature by empirically examining its mediating role between workplace resources and HCWs’ health and work-related outcomes.
    • ‘Mind the gap”: extending outcome measurement for accountability and meaningful innovation

      Johnson, R.E.; Kerridge, Gary; Alderson, Hayley; Currie, Graeme; Friel, Seana; Harrop, Carrie; Lynch, Amy; McGovern, Ruth; Munro, Emily; Newlands, Fiona; et al. (Oxford University Press, 2024-02-21)
      We examine the outcome measurement landscape in care leaver innovation, where many innovations to support transitions of young people leaving care fail to sustain beyond a fixed-term pilot, and fewer impact wider transition policies. Our empirical qualitative study comprises interviews with 31 senior UK children’s social care policy and practice professionals, 103 interviews across five innovation-focused case studies within England with a range of public and private providers. We consider these data in relation to evaluations from a nationally diffused social care innovation. We identified three measurement landscape challenges. First, we highlight the limits of the economically-oriented measurement and identify an overlooked outcome measurement demand. Second, we emphasise a need to stratify care leaver population outcomes to better reflect individuals transition through different domains of life and trajectory. Third, we identify areas of precarity around intended use of care leaver experience. We conclude that tensions exist between the pull toward a unified approach to outcome measurement and the reality of decoupled outcome requirements and legitimacy-seeking priorities which differ according to stakeholder. These tensions entrench stagnant innovation. Recognition of roles and legitimacies that exist across the process of care leaver innovation is warranted. Opportunities for action are discussed.
    • Comparing leaving-care policy and practice across the four nations of the United Kingdom: exploring similarities, differences, and implementation gaps

      Munro, Emily; Kelly, Berni; Mannay, Dawn; McGhee, Kenny; University of Bedfordshire; Queen's University Belfast; Cardiff University (Routledge, 2024-02-22)
      From an international comparative perspective, the four nations of the UK have robust legal and policy frameworks governing care-leaving. Measures taken include: access to aftercare workers; pathway planning; introduction of extended care arrangements (permitting young people to remain in placement beyond 18 years); and specific types of financial support. The paper explores commonalities and differences in approaches across the UK and illuminates how resource constraints, placement availability, workforce challenges and cultural norms may result in implementation gaps and a post-code lottery of provision. Findings lend weight to calls for attentiveness to, and systematic evaluation of, the implementation process to understand the challenges encountered in embedding effective support for care leavers. They also highlight the value of further comparative studies that explore the systems and subsystems of law, policy and practice in the four nations to contribute to more informed leaving care policy and practice.
    • The effects of adapted mind-body exercises on physical function, quality of life and wellbeing for older people: a systematic review and meta-analysis

      Tanhamira, Lesley-Anne; Randhawa, Gurch; Hewson, David; University of Bedfordshire (Elsevier, 2024-02-14)
      Participating in physical activity programmes is one way to optimise wellbeing and quality of life in older adults. Mind-body exercises could provide greater benefits than other forms of traditional physical activity and can be easily adapted for older people who are starting to develop functional decline. To synthesise the literature looking at the effects of adapted mind-body interventions on older people. A systematic review and meta-analysis was conducted on articles from Web of Science, MEDLINE, SPORTDiscus, AMED and CINAHL that were searched up to 13 September 2023. Studies were extracted and assessed by two authors and included if they were adapted mind-body quasi experimental trials (QET) or randomised controlled trials (RCT) evaluating physical function, quality of life or wellbeing in community dwelling older adults aged 60 years and over. The Cochrane Risk of Bias 2 scale was used for quality appraisal. Analysis of the results included calculating standardised effect sizes (Hedge's g) and a narrative synthesis of results not included in meta-analysis. 18 studies (8 quasi-experimental trial designs, n = 310; 10 randomised control trials, n = 1829) were included in the systematic review, with 14 studies (9 RCT, n = 1776, 5 QET, n = 100) retained for meta-analysis. For the RCT studies, some improvement was noted in mobility (ES 0.36: 95% CI: 0.01, 0.71), flexibility (ES 0.36: 0.01, 0.70), well-being (ES 0.54: 0.18, 0.91) and quality of life (ES 0.50: 0.21, 0.79). No positive effect was observed for leg power (ES 0.09: -0.33, 0.51), leg endurance (ES 0.16: -0.72, 1.03), back scratch test (ES 0.24: -0.10, 0.59), or balance, (ES 0.05: -0.06, 0.15). Heterogeneity varied from 0%-87% across the different outcomes. For the QET studies, gait velocity was shown to improve (ES 0.54: 0.18, 0.91), while fear of falling showed no significant improvements (ES 0.82: -0.06, 1.69). A meta-regression for quality of life in which the total physical activity of the intervention, in hours, was used as a covariate, showed ES = 1.1 for every 100 h of physical activity. There is scope for adapted mind-body physical activity interventions to play a role in improving quality of life, wellbeing, and physical function in older adults. The provision of adapted interventions for older people might improve uptake of and engagement with physical activity interventions in older people with limited or reduced abilities.
    • What does the mid-1990s soybean liberalization tell us about the role of foreign investment in China's rural industrialization?

      Fares, Tomaz Mefano; University of Bedfordshire (Taylor and Francis, 2024-01-09)
      This article reassesses the role of foreign investments in China’s rural industrialization in the 1980s and the early 1990s. It draws upon the power disputes between agribusiness transnational corporations (TNCs) and central domestic players in the country’s soybean complex. I follow Chris Bramall’s argument that food processing infrastructure grew progressively since the Maoist era in the 1960s and 1970s, instead of springing from foreign investments or pro-business local state officials during the reform and opening up. However, I go beyond this assumption by suggesting that foreign investments often had a detrimental role in rural industrialization, depending on their political action. I show through in-depth empirical analyses that due to the Maoist industrial legacy, soybean processors from Northeast China consolidated an endogenous form of accumulation based on local circuits of production and consumption under state protectionism. This specific industrialization trajectory has put them on opposite sides from agribusiness TNCs. The liberalization agenda pushed by the TNCs through bilateral and multilateral levels of influence culminated in the opening of China’s soybean imports in the late 1990s, allowing the consolidation of their global trade monopoly to the detriment of domestic players.
    • Beyond monolithic threat: understanding risk typology in court-involved Black male youth

      Onifade, Eyitayo; Campbell, Christina; Shishane, Kwanele; Annan, Sylvia; Odotei, Emma; Williams, Justin B.; Clark Atlanta University; University of Cincinnati; University of Bedfordshire; University of Wisconsin-Madison (Taylor and Francis, 2024-02-12)
      Black male youth are at greatest risk of disparate contact and detention in the U.S. juvenile justice system. This study aims to identify recidivism risk/need patterns among African American male youth in the Ohio juvenile justice system, utilizing cluster analysis of risk assessment data from the Ohio Youth Assessment System-Disposition (OYAS-DIS). We found four distinct risk patterns and accompanying recidivism rates in the Black male youth population. Two of the clusters exhibited moderate levels of risk. However, they had significantly different recidivism outcomes, suggesting certain combinations of risk factors have more or less impact the propensity for crime in the Black male sample. Implications for policy and practice are discussed, as well as future directions for research.
    • Revolutionising financial portfolio management: the non-stationary transformer's fusion of macroeconomic indicators and sentiment analysis in a deep reinforcement learning framework

      Liu, Yuchen; Mikriukov, Daniil; Tjahyadi, Owen Christopher; Li, Gangmin; Payne, Terry R.; Yue, Yong; Siddique, Kamran; Man, Ka Lok; Xi’an Jiaotong-Liverpool University; University of Liverpool; et al. (MDPI, 2023-12-28)
      In the evolving landscape of portfolio management (PM), the fusion of advanced machine learning techniques with traditional financial methodologies has opened new avenues for innovation. Our study introduces a cutting-edge model combining deep reinforcement learning (DRL) with a non-stationary transformer architecture. This model is designed to decode complex patterns in financial time-series data, enhancing portfolio management strategies with deeper insights and robustness. It effectively tackles the challenges of data heterogeneity and market uncertainty, key obstacles in PM. Our approach integrates key macroeconomic indicators and targeted news sentiment analysis into its framework, capturing a comprehensive picture of market dynamics. This amalgamation of varied data types addresses the multifaceted nature of financial markets, enhancing the model’s ability to navigate the complexities of asset management. Rigorous testing demonstrates the model’s efficacy, highlighting the benefits of blending diverse data sources and sophisticated algorithmic approaches in mastering the nuances of PM.
    • The effects of growth mindset and resilience on immigrant students' PISA science achievement: the mediating role of attitudes toward school

      Kaya, Sibel; Eryilmaz, Nurullah; Yuksel, Dogan; University of Bedfordshire; University of Bath; Open University (SAGE, 2024-01-29)
      In recent years, self-theories such as growth mindset and resilience have gained interest as they have a sizable influence on achievement and school-related motivation. The aim of this study is to investigate the relationship between immigrant students’ growth mindset, resilience, and science achievement in PISA 2018 by considering the mediating effect of attitudes toward school. Using secondary data for Australia, the UK, and the USA obtained from PISA 2018, we conducted a series of Structural Equation Modeling analyses to unravel the relationship between self-theories and science achievement. The growth mindset had the strongest effect on science achievement for both immigrants and non-immigrants in all three countries; resilience was positively related to science achievement for immigrants in the US, and attitudes toward school were positively related to science achievement for immigrants in Australia. The mediating role of attitudes toward school between growth mindset, resilience and science achievement could not have been confirmed. We speculate that self-theories might be affecting immigrant groups differently in different countries. Implications regarding these findings are discussed.
    • Forced migration: a relational wellbeing approach

      Kohli, Ravi K.S.; Fylkesnes, Marta Knag; Kaukko, Mervi; White, Sarah C.; University of Bedfordshire; Norwegian Research Centre; Tampere University; Relational Wellbeing (RWB) Collaborative (MDPI, 2024-01-15)
      Editorial. In this Special Issue, we consider the ways in which a relational wellbeing approach can be used to understand the lives and trajectories of refugees in general and young refugees in particular. We mainly focus on the lives of young adults who came to the global North as unaccompanied children—that is, without an adult responsible for them when they claimed asylum. Many of the papers report from the Drawing Together project (see, accessed on 11 January 2024). The project focus is on ‘relational wellbeing’ for young refugees—that is, wellbeing that is experienced through actions that repair and amplify a sense of responsibility they and other people have to each other. Hospitality and reciprocity emerge through small acts of fellowship. In time, these build patterns of exchanges between young refugees and those important to them, leading to a mutual sense of ‘having enough’, ‘being connected’, and ‘feeling good’ (White and Jha 2020). This is wellbeing as a shared endeavour. Overall, the project and many contributions in this Special Issue stand at the conjunction between fields of research into wellbeing and refugee studies. The papers span contexts and countries, offering a sense of an international array of experiences, joined by an issue of supra-national importance—that is, the ways interaction and relationality mediate the experiences of becoming and being a refugee.
    • Coping with COVID-19 lockdown: a qualitative study of older adults in alcohol treatment

      Trevena, Paulina; Seddon, Jennifer L.; Elliott, Lawrie; Wadd, Sarah; Dutton, Maureen; University of Glasgow; Oxford Brookes University; Glasgow Caledonian University; University of Bedfordshire (Cambridge University Press, 2024-01-19)
      The COVID-19 global pandemic had a major impact on older people's mental health and resulted in changes in alcohol use, with more older adults increasing than decreasing consumption levels among the general population. So far, no studies have focused on older people who were already experiencing problem alcohol use. This qualitative research is the first to provide a nuanced understanding of changes to drinking patterns among older adults engaged in alcohol treatment during the COVID-19 pandemic, and the implications of these for practice. We conducted 30 semi-structured interviews with people in alcohol treatment aged 55+ living in urban and rural areas across the UK. Data were analysed using thematic analysis. We found that changes in alcohol use varied depending on the social, economic and health impacts of the pandemic on older adults. Boredom, lack of adequate medical or emotional support, and key life changes experienced during the pandemic (such as bereavement or retirement) increased the risk of increased drinking. Moreover, some people in longer-term alcohol treatment were struggling to maintain abstinence due to lack of face-to-face peer support. For others, decreased drinking levels were a side-effect of lockdown policies and restrictions, such as alcohol-related hospitalisations, closure of social spaces or inability to source alcohol; these also supported those who decided to cut down on drinking shortly before the pandemic. Generally, older adults who developed home-based interests and self-care practices managed lockdown best, maintaining abstinence or lower risk drinking levels. Based on these results, we argue that multilevel interventions aimed at strengthening resilience are required to reduce drinking or maintain abstinence among older adults. Such interventions should address three domains: individual (coping strategies and mindset), social (support networks), and structural (access to resources). In preparation for supporting older alcohol users through prospective future pandemics, building digital literacy and inclusion are essential.
    • A question of age? applying desistance with children

      Wigzell, Alexandra; Bateman, Tim; University of Cambridge; University of Bedfordshire (SAGE, 2024-01-23)
      Youth justice in England and Wales has seen the increasing adoption of desistance thinking in recent years. There has been scarce academic debate of this development, despite the desistance evidence base focussing on adult pathways away from crime. This article examines the theorisation and application of desistance thinking with children, centring on the experiences and narratives of four ‘groups’ involved in the formal youth justice system in England and Wales, across two empirical studies. It challenges previous scholarship that denies the relevance of desistance theories to under-18s, arguing for progressive desistance practice that prioritises children’s healthy long-term development.
    • Leading modes and feature zones of sea ice concentration in North Pacific during Spring seasons of 2000–2020

      Xu, Li; Crabbe, M. James C.; BYD Company Ltd; Oxford University; University of Bedfordshire (World Scientific, 2024-01-23)
      Under the influence of the Arctic amplification, sea ice variability in North Pacific is becoming a key indicator of global climate changes. Due to the widespread and complex impacts of North Pacific sea ice variations, the understanding of its dynamic changes, especially its spatial and temporal evolution patterns, has great significance. In this study, we used the rotated empirical orthogonal decomposition to divide the whole North Pacific into six feature zones on the evolution sea ice concentration under the recent global warming and highlighted the complexity and diversity of sea ice variations in the offshore waters.
    • Book review: Coming and going

      Giudice, Nicolo; University of Bedfordshire (2023-12-15)
      Book Review Coming and Going By Jim Goldberg, MACK, London. 75£, ISBN: 978-1-912339-77-8 Jim Goldberg's new book, Coming and Going (Mack, 2023) takes the viewer on a breath-taking autobiographical journey, which traces a path through time and layers of photographic images, collages, texts, documents, drawings, and ephemera. The book itself is a substantntially large and thick object, one that brings to mind a scrapbook, a family album, a home movie, a diary and a book dummy. Its dimension and scale make it an extensive and immersive art object.
    • Person reference and a preference for association in emergency calls

      Tennent, Emma; Weatherall, Ann; Victoria University of Wellington; University of Bedfordshire (Routledge, 2024-02-12)
      Person reference is pervasive in talk. Conversation analytic work has identified preferences in person reference relating to recognitional reference. However, the principles shaping non-recognitional reference are less well understood. We propose a preference for association in an institutional setting where recognition is not relevant. Our data are calls to the New Zealand police emergency line which were institutionally classified as family harm. Using a collection methodology, we found that non-recognitional person reference typically takes the form my x which directly associates speaker and referent, for example “my partner”, “my ex-partner”, “my dad”. Initial references that suggest no association (e.g. “someone” or “an abusive guy”) were subsequently revised by callers using self-repair or targeted by call-takers through questions that seek clarification about association. The shifts from non-associative to associative references demonstrate participants’ orientations to the relevance of association and are evidence of a preference for association in the setting under examination. Data are in English.
    • Digital financial inclusion in emerging economies: evidence from Jordan

      Al-Khub, Abdalla Fuad; Saeudy, Mohamed; Gerged, Ali Meftah; University of Bedfordshire; Sheffield University; Misurata University (MDPI, 2024-02-08)
      This study explores the role of digital financial inclusion in mitigating poverty and bolstering economic growth, with a special focus on developing nations during the COVID-19 era. Centering on Jordan, it seeks to identify key influencers of financial access by analyzing data from 260 participants using a non-linear probit regression model. The research uncovers a significant disparity in financial inclusion between Jordanian adult males and females, attributable to differences in education, wealth, employment, and income levels. These findings point to the necessity of prioritizing financial accessibility for marginalized groups such as women, the elderly, and those with lower income to effectively combat poverty and facilitate economic advancement and sustainable development in emerging markets.
    • An institutional perspective on the shifts in banking and capitalist ideology: ‎sustainability, social, and environmental insights

      Saeudy, Mohamed; Hussainey, Khaled; ; University of Bedfordshire (Emerald, 2024-04-09)
      Purpose – This paper investigates the development of moralised business ideologies (MBIs) among sustainable banks as they navigate social and environmental business prospects. Methodology –Empirical evidence is drawn from top-management-level interviews with 16 UK-based small and medium-sized banks that specialise in financing social and environmental projects. Findings – MBIs have emerged in the literature review and empirical data analysis as a new concept taken on by sustainable banks with roots closer to MBIs such as ethical practices, moralised values, sustainable business models, and ecological standards. The results confirm that MBIs help banking institutions to create a more sustained positive impact in terms of social and environmental business opportunities. Originality– This paper offers novel evidence on the intersection between banking and MBIs with a focus on social and environmental considerations.
    • Preparation of a novel metallothionein-AuNP composite material by genetic modification and Au–S covalent combination

      Li, Xuefen; Liu, Hui; Wang, Yuxia; Crabbe, M. James C.; Wang, Lan; Ma, Wenli; Ren, Zhumei; Shanxi University; University of Oxford; University of Bedfordshire (Elsevier, 2024-02-05)
      Metallothionein (MTs) can be used in the prevention and treatment of tumors and diabetes due to its antioxidant properties. However, it is necessary to solve its non-transmembrane properties and further improve its antioxidant activity, increase its fluorescence visualization and enhance its stability to meet practical applications in the biomedical field. Here, we report the preparation of a novel metallothionein-AuNP composite material with high transmembrane ability, fluorescence visualization, antioxidant activity, and stability by genetic modification (introducing transduction peptide TAT, fluorescence tag GFP and increasing sulfydryl groups) and immobilization technology (covalently bonding with AuNPs). The transmembrane activity of modified proteins was verified by immunofluorescence. Increasing the sulfhydryl content within a certain range can enhance the antioxidant activity of the protein. In addition, GFP were used to further simplify the imaging of the metallothionein-AuNP composite in cells. XPS results indicated that AuNPs can immobilize metallothionein through Au–S covalent bonds. TGA characterization and degradation experiments showed that thermal and degradation stability of the immobilized material was significantly improved. This work provides new ideas to construct metallothionein composites with high transmembrane ability, antioxidant activity, fluorescence visualization and stability to meet novel applications in the biomedical field.
    • A study of advanced RTO (Regenerative Thermal Oxidizer) technology by optimised combustor integration and carbon-free fuel for non-carbon emissions

      Liu, Jingyin (University of BedfordshireUniversity of Bedfordshire, 2024-01)
      The control of emissions of VOCs (Volatile Organic Compounds) has been an important issue when environmental standards has been starting to implement. Thermal Oxidation which involves combustion processes of gases, liquids and solids has been a common technique to destroy VOCs and has a vast application prospect, especially the application of regenerative thermal oxidizer (RTO). In this thesis which is aiming to investigate advanced RTO technology by optimised integration with combustor(s) and by carbon-free fuel for non-carbon emissions, based on necessary literature review on advanced RTO technologies, main methodology to study and optimize RTO (Regenerative Thermal Oxidation) performances, current development of relevant numerical simulation, non-carbon combustion with carbon-free fuels, experimental investigation and CFD simulation have been carried out for examining effects of various design parameters and operation parameters on VOC conversion efficiency, energy application and non-carbon emissions. After the experimental equipment, instrumentations and testing conditions for initial experimental investigation are introduced, influences of operating temperatures and purging time on gas-out VOC concentration have been examined. Those results suggest that to maintain a lower gas-out VOC concentration but keep low fuel consumption and low combustion temperature still need significant work to do. The CFD numerical model including relevant sub-models have been introduced and developed. Based on those, the required meshes have been created and presented. Initial validations show the modelling results have very good agreement with the experimental results. It suggested the developed CFD model can be used for simulating the performance of three-bed RTO. Then the integration between combustor(s) and RTO has been investigated with CFD simulation. Five sections Including combustor protrusion, combustor diameter (or combustor exit velocity), combustor vertical position, combustor horizontal position, twin combustor were studied for examining their influences on temperature distributions, flow field, VOC concentration distributions, VOC concentration in gas-out flow, NO emissions etc. In summary, combustor horizontal position can provide a better solution for reducing both VOC and NO outputs, while twin combustor is not so promising for benefiting RTO performance improvement. As hydrogen can provide zero CO2 emissions and other emissions except NOx, it as fuel was studied with the main objective to explore the possibility for RTO to implement carbon-free combustion and emissions,. The same heat amount with hydrogen as fuel was supplied for comparing the difference between hydrogen as fuel and natural gas as fuel. When stoichiometric combustion is maintained for both natural gas fuel and hydrogen fuel, modelling cases for same combustor diameter and same combustor exit velocity are simulated. Results show that, although the same heat amount is supplied with hydrogen as fuel, both the same combustor diameter case and the same combustor exit velocity case produce higher VOC concentration in gas-out flows. The reason may be the reduced temperature in most RTO space due to more water condensation for hydrogen combustion. Reduced hydrogen amount/flowrate was also investigated for examining effects of reduced energy supply on RTO performance. Results show that reduced hydrogen amount will almost proportionally increase VOC concentration in gas-out flows. With the same heat amount for hydrogen as fuel, NO emissions have no big difference, compared to natural gas although VOC amount increased. With reduced hydrogen amount/flowrate, NO emissions amount has some slight reduction. It suggests that both reduced temperature in most RTO space due to water condensation and increased flame temperature of hydrogen combustion contribute to the results.
