    An embodied approach to informational interventions: using conceptual metaphors to promote sustainable healthy diets

    Get PDF
    Poor diet quality and environmental degradation are two major challenges of our times. Unhealthy and unsustainable dietary practices, such as the overconsumption of meat and consumer food waste behaviour, contribute greatly to both issues. Across seventeen online and field experiments, in two different cultures (US and China), this thesis investigates if the embodied cognition approach, and more specifically, research on conceptual metaphors, can be used to develop interventions to promote sustainable healthy diets. Interventions relying on conceptual metaphors have been shown to stimulate attitudinal and behavioural changes in other fields (e.g., marketing and political communications), but are rarely adopted to encourage sustainable healthy diets. To fill in this gap in the literature, I conducted five sets of experimental studies examining the effects of different metaphors on specific sustainable healthy dietary practices, each of which forms an independent empirical paper (Chapters 2-6 of the thesis). After introducing the current perspectives on embodied cognition and conceptual metaphors in the context of this research (Chapter 1), Chapter 2 looks into the conceptual metaphor “Healthy is Up”, demonstrating that US people implicitly associate healthiness with verticality, and offering recommendations for healthy eating guidelines. Chapter 3 extends this research to Chinese samples and partially replicates the results. Chapter 4 shows that the anthropomorphic metaphor “Animals are Friends” discourages meat consumption by inducing anticipatory guilt among US omnivores, whereas Chapter 5 reveals that Chinese omnivores are more responsive to another anthropomorphic metaphor, namely, “Animals are Family”. Bringing lab insights 6 to the real world, Chapter 6 demonstrates with a longitudinal field experiment that anthropomorphic metaphors together with environmental feedback result in a higher reduction in food waste as compared to other feedback interventions. The strengths, limitations and implications of those empirical papers are discussed in the conclusive part of the thesis

    Talking about personal recovery in bipolar disorder: Integrating health research, natural language processing, and corpus linguistics to analyse peer online support forum posts

    Background: Personal recovery, ‘living a satisfying, hopeful and contributing lifeeven with the limitations caused by the illness’ (Anthony, 1993) is of particular value in bipolar disorder where symptoms often persist despite treatment. So far, personal recovery has only been studied in researcher-constructed environments (interviews, focus groups). Support forum posts can serve as a complementary naturalistic data source. Objective: The overarching aim of this thesis was to study personal recovery experiences that people living with bipolar disorder have shared in online support forums through integrating health research, NLP, and corpus linguistics in a mixed methods approach within a pragmatic research paradigm, while considering ethical issues and involving people with lived experience. Methods: This mixed-methods study analysed: 1) previous qualitative evidence on personal recovery in bipolar disorder from interviews and focus groups 2) who self-reports a bipolar disorder diagnosis on the online discussion platform Reddit 3) the relationship of mood and posting in mental health-specific Reddit forums (subreddits) 4) discussions of personal recovery in bipolar disorder subreddits. Results: A systematic review of qualitative evidence resulted in the first framework for personal recovery in bipolar disorder, POETIC (Purpose & meaning, Optimism & hope, Empowerment, Tensions, Identity, Connectedness). Mainly young or middle-aged US-based adults self-report a bipolar disorder diagnosis on Reddit. Of these, those experiencing more intense emotions appear to be more likely to post in mental health support subreddits. Their personal recovery-related discussions in bipolar disorder subreddits primarily focussed on three domains: Purpose & meaning (particularly reproductive decisions, work), Connectedness (romantic relationships, social support), Empowerment (self-management, personal responsibility). Support forum data highlighted personal recovery issues that exclusively or more frequently came up online compared to previous evidence from interviews and focus groups. Conclusion: This project is the first to analyse non-reactive data on personal recovery in bipolar disorder. Indicating the key areas that people focus on in personal recovery when posting freely and the language they use provides a helpful starting point for formal and informal carers to understand the concerns of people diagnosed with bipolar disorder and to consider how best to offer support

    The Omnichannel phenomenon: unveiling the role of Channel Integration for consumers and retailers

    Get PDF
    This thesis work is aimed at deepening the knowledge of the phenomenon called "Omnichannel", as the main challenge of modern retailing. Omnichannel is a new retailing configuration, which envisages drastic changes compared to the Multi- and Cross-channel models. Although the Omnichannel phenomenon has been extensively studied in recent years, it is also missing a comprehensive framework. This is also shown by the variety of alternative definitions of "Omnichannel" existing in literature. The three studies presented in this thesis start from this assumption, and come to identify and investigate an element that clearly emerges as the core of Omnichannel: Channel Integration. The first study, an extensive literature review conducted with bibliometric techniques, allowed us to frame the extent of Omnichannel in terms of papers, topics and issues addressed. Furthermore, through the use of co-citation analysis, a clustering technique based on the triangulation of citations, the theoretical foundations of Omnichannel have been identified. 4 research clusters were traced back to: Consumer Behavior, Strategic Management, Channel Management, and Channel Integration. Results also show that Channel Integration is the main element of Omnichannel, capable of creating synergies with other clusters and capturing the perspectives of the consumer and retailer at the same time. The second study qualifies as an extension of these results to the future of Omnichannel, through qualitative research. It was in fact decided to proceed by discussing the topic with a panel of 18 international experts, with proven academic and managerial background. The participants commented on the results emerging from our previous study and expressed themselves on: areas, topics, methodologies and settings of priority development; generation of new theories or application of pre-existing theories; challenges, issues and retailers’ needs in Omnichannel. The results were then coded and analyzed to create a research agenda divided into 5 macro-themes of interest: a) Omnichannel customer journeys, b) Omnichannel customer experiences, c) Omnichannel transition issues, d) the human factor in Omnichannel, and e) augmented and intelligent Omnichannel environments. The experts also validated the model in 4 research clusters proposed by our first study and confirmed the central role of Channel Integration. For the third and final study, we therefore decided to investigate the role of Channel Integration in Omnichannel contexts, from the perspective of customer journeys (theme a) emerging from Study 2). We employed quantitative methodologies (MCA, CFA, SEM) to test the effect of touchpoints - which constitute the various steps of customer journeys - on consumers’ perception of Channel Integration, and the effect of the latter on patronage intention towards the retailer. Through the Categorization Theory, we proposed that the touchpoints capable of activating a Channel Integration perception are different depending on the sector and on the type of consumer (first-time and repeat customer). The research, conducted on two panels of Italian consumers in the grocery and fashion sectors – 1.031 and 759 participants, respectively –, led to the identification of substantial differences related to context and target, and confirmed a positive effect of Channel Integration perception on customer loyalty through patronage intention. The work therefore has, overall, both theoretical and managerial implications.Il presente lavoro di tesi è volto ad approfondire la conoscenza del fenomeno denominato Omnicanalità, quale principale sfida del retailing moderno. Si tratta di una nuova configurazione di retailing, che prevede cambiamenti drastici rispetto ai modelli di Multi- e Cross-canalità che l’hanno preceduta. Nonostante si tratti di un fenomeno ampiamente studiato negli ultimi anni, abbiamo rilevato una sostanziale difficoltà nel suo inquadramento, che si evince anche dalla molteplicità di definizioni alternative di “Omnicanalità” esistenti in letteratura. I tre studi che costituiscono questa tesi partono da questo presupposto, arrivando ad individuare e investigare l’elemento che emerge chiaramente come il fulcro dell’Omnicanalità. Il primo studio, una estesa literature review condotta con tecniche bibliometriche, ci ha permesso di inquadrare l’Omnicanalità in termini di studi condotti in letteratura e tematiche affrontate. Inoltre, mediante la co-citation analysis, una tecnica di clustering basata sulla triangolazione delle citazioni, sono state ricostruite le basi teoriche dell’Omnicanalità. Attraverso l’interpretazione dei contributi fondamentali così individuati, sono stati identificati 4 cluster di ricerca: Consumer Behavior, Management Strategico, Channel Management, e Channel Integration. Dall’analisi emerge anche come la Channel Integration sia l’elemento centrale dell’Omnicanalità, in grado sia di creare sinergie con gli altri cluster sia di catturare al contempo le prospettive del consumatore e del retailer. Il secondo studio si qualifica come un’estensione di tali risultati al futuro dell’Omnicanalità, attraverso un’analisi di tipo qualitativo. Si è infatti deciso di procedere discutendo il tema con un panel di 18 esperti internazionali, dalla comprovata esperienza sia accademica che professionale. I partecipanti hanno commentato i risultati emergenti dallo studio precedente e si sono espressi in merito a: aree, temi, metodologie e contesti prioritari per lo studio dell’Omnicanalità; sfide, problematiche e necessità di ricerca in tale ambito. I risultati sono stati codificati e analizzati per produrre una research agenda articolata in 5 macro-tematiche di interesse: a) Omnichannel customer journeys, b) Omnichannel customer experiences, c) problematiche di transizione verso l’Omnicanalità, d) il fattore umano nell’Omnicanalità, ed e) la gestione di ambienti Omnicanale tecnologicamente avanzati ed intelligenti. Gli esperti hanno inoltre validato il modello in 4 research clusters da noi proposto e confermato la centralità della Channel Integration. Per il terzo ed ultimo studio, si è pertanto deciso di investigare ulteriormente il tema della Channel Integration in contesti Omnicanale, secondo la prospettiva delle customer journeys (punto a) emerso dal secondo studio). Attraverso metodologie quantitative (MCA, CFA, SEM), si testa l’effetto dei touchpoints – che costituiscono i vari step delle customer journeys – sulla percezione di Channel Integration maturata dal consumatore, e l’effetto di questa sulla patronage intention verso il retailer. Attraverso la Categorization Theory, si propone che i touchpoint in grado di attivare una percezione di Channel Integration siano diversi a seconda del contesto settoriale – sulla base di differenti categorie di prodotto – e della tipologia di consumatore (first-time e repeat customer). La ricerca, condotta su due panel di consumatori italiani nei settori grocery e fashion – con 1.031 e 759 partecipanti, rispettivamente –, ha portato all’individuazione ed alla discussione di tali touchpoint, evidenziando differenze sostanziali tra i touchpoint che determinano la channel integration tra settori e tra target, e ha confermato un effetto positivo della percezione di Channel Integration sulla customer loyalty attraverso la patronage intention. Il lavoro presenta pertanto implicazioni sia teoriche che manageriali

    Facilitating prosociality through technology: Design to promote digital volunteerism

    Volunteerism covers many activities involving no financial rewards for volunteers but which contribute to the common good. There is existing work in designing technology for volunteerism in HumanComputer Interaction (HCI) and related disciplines that focuses on motivation to improve performance, but it does not account for volunteer wellbeing. Here, I investigate digital volunteerism in three case studies with a focus on volunteer motivation, engagement, and wellbeing. My research involved volunteers and others in the volunteering context to generate recommendations for a volunteer-centric design for digital volunteerism. The thesis has three aims: 1. To investigate motivational aspects critical for enhancing digital volunteers’ experiences 2. To identify digital platform attributes linked to volunteer wellbeing 3. To create guidelines for effectively supporting volunteer engagement in digital volunteering platforms In the first case study I investigate the design of a chat widget for volunteers working in an organisation with a view to develop a design that improves their workflow and wellbeing. The second case study investigates the needs, motivations, and wellbeing of volunteers who help medical students improve their medical communication skills. An initial mixed-methods study was followed by an experiment comparing two design strategies to improve volunteer relatedness; an important indicator of wellbeing. The third case study looks into volunteer needs, experiences, motivations, and wellbeing with a focus on volunteer identity and meaning-making on a science-based research platform. I then analyse my findings from these case studies using the lens of care ethics to derive critical insights for design. The key contributions of this thesis are design strategies and critical insights, and a volunteer-centric design framework to enhance the motivation, wellbeing and engagement of digital volunteers

    Vitalism and Its Legacy in Twentieth Century Life Sciences and Philosophy

    Get PDF
    This Open Access book combines philosophical and historical analysis of various forms of alternatives to mechanism and mechanistic explanation, focusing on the 19th century to the present. It addresses vitalism, organicism and responses to materialism and its relevance to current biological science. In doing so, it promotes dialogue and discussion about the historical and philosophical importance of vitalism and other non-mechanistic conceptions of life. It points towards the integration of genomic science into the broader history of biology. It details a broad engagement with a variety of nineteenth, twentieth and twenty-first century vitalisms and conceptions of life. In addition, it discusses important threads in the history of concepts in the United States and Europe, including charting new reception histories in eastern and south-eastern Europe. While vitalism, organicism and similar epistemologies are often the concern of specialists in the history and philosophy of biology and of historians of ideas, the range of the contributions as well as the geographical and temporal scope of the volume allows for it to appeal to the historian of science and the historian of biology generally

    Developing Socially-Just Teachers Through A Proposed Alternative Curriculum For Initial Teacher Education

    Get PDF
    Problems of teacher burnout, low job satisfaction and high rates of teacher attrition are not specific to England but are also global concerns and symptomatic of a profession in crisis. In England, teacher education is a highly regulated sector and, in recent years, has become increasingly complex, fragmented and marketised. Increased government control over what pre-service teachers learn during their initial training phase has resulted in a centralised teacher training curriculum which is both reductionist and situates teachers as technicians. Universities have always played a distinctive role in teacher education, but the marketisation of the sector in recent years has led to a de-professionalisation and re-professionalisation of university teacher educators. The disappearance of universities from teacher training policy discourse and the tightening of government control over what is taught to pre-service teachers reflects a lack of trust in the university teacher education sector. Given this aggressive policy context, it is not surprising that some higher education institutions in England have withdrawn their teacher education courses. Courses which were once the ‘bread and butter’ of many institutions are now viewed as a reputational risk. Inspection regimes seek to enforce the government prescribed curriculum and there are heavy penalties that are imposed on institutions where the prescribed curriculum is not being delivered in its entirety or where it is not being taught in sufficient depth. The government curriculum is reductionist and produces teachers as technicians who believe in and can implement the prescribed approaches. This thesis presents 13 published papers. Implications to support the development of an alternative teacher education curriculum are drawn from the findings. The findings of the papers demonstrate that matters of inclusion and social justice need to be given greater emphasis in teacher education to enable pre-service teachers to respond to the professional challenges that they will face in classrooms. Key broad themes drawn from the papers include teacher identity, social justice and inclusion as critical components of a teacher education curriculum. These themes are used to develop a proposed curriculum framework for initial teacher education, which aims to situate teachers as critical thinkers who can challenge government policy, advance equality and prioritise both their own mental health and the mental health of their students. In addition, a framework for a mentor curriculum is also proposed to support the implementation of the teacher education curriculum in schools

    Examining the Relationships Between Distance Education Students’ Self-Efficacy and Their Achievement

    This study aimed to examine the relationships between students’ self-efficacy (SSE) and students’ achievement (SA) in distance education. The instruments were administered to 100 undergraduate students in a distance university who work as migrant workers in Taiwan to gather data, while their SA scores were obtained from the university. The semi-structured interviews for 8 participants consisted of questions that showed the specific conditions of SSE and SA. The findings of this study were reported as follows: There was a significantly positive correlation between targeted SSE (overall scales and general self-efficacy) and SA. Targeted students' self-efficacy effectively predicted their achievement; besides, general self- efficacy had the most significant influence. In the qualitative findings, four themes were extracted for those students with lower self-efficacy but higher achievement—physical and emotional condition, teaching and learning strategy, positive social interaction, and intrinsic motivation. Moreover, three themes were extracted for those students with moderate or higher self-efficacy but lower achievement—more time for leisure (not hard-working), less social interaction, and external excuses. Providing effective learning environments, social interactions, and teaching and learning strategies are suggested in distance education
