Unveiling the Secrets of Collaboration on Video-Sharing Platforms

In online video platforms, collaborative content creation gains popularity as vloggers exchange social capital to boost content’s appeal and personal visibility. However, existing research lacks rigorous verification of collaboration efficacy in this context. This study investigates the benefits of collaboration on vlogger influence within the online video domain. Utilizing a staggered difference-in-differences approach, we found that collaboration indeed generates positive impact on vloggers’ influence, as evidenced by the significant increases of their fan and like numbers among the audience. However, managing collaboration activities with suitable intensity is vital, as the marginal utility of collaborations diminishes with increased collaboration numbers. Furthermore, vloggers should avoid excessive non-core activities (e.g., uploading photo albums, audios, and articles) post-collaboration, as these peripheral activities negatively affect collaboration benefits in online video contexts. We believe that the findings of our study will provide helpful guidelines for designing more effective collaboration strategies on video sharing platforms

Educating and Supporting Tennis Parents Using Web-Based Delivery Methods: A Novel Online Education Program

This is an Accepted Manuscript of an article published by Taylor & Francis in Journal of Applied Sport Psychology on 23 Feb 2018, available online: https://doi.org/10.1080/10413200.2018.1433250This study evaluated the effectiveness of a novel online education program for British tennis parents and their experiences of engaging in the program. Using a convergent parallel mixed-methods design, 13 parents completed pre- and post-program online questionnaires, while a subset of 9 participants also shared their experiences via an asynchronous email interview. Quantitative findings revealed positive directional changes for almost all of the variables in relation to emotional experiences, goal orientations, tennis parent efficacy, and general parenting efficacy. The contribution of the combined quantitative and qualitative findings and their practical implications are discussed

The Business of Influencing: Business Models of Social Media Influencers – a Literature Review

Purpose: Influencer Marketing (IM) has become an important marketing category and has, in turn, led to the rise of so-called social media influencers (SMI), who as a group generate significant economic activity. Whereas IM has been studied extensively from an advertiser or effectiveness perspective, addressing the issue from the perspective of SMIs and their economic activities – how they generate, deliver and capture value – has received relatively little attention. Therefore, this study reviews and conceptually represents the current state of knowledge on business models of SMIs. Methodology: Structured literature review of peer-reviewed, English-language journals in Scopus database between 2017-2022. The findings are organised according to Osterwalder and Pigneur’s nine-dimension business model concept, adapted to service-dominant logic aspects following Ojasalo & Ojasalo (2015). Findings/Contribution: Value generation, delivery and capture in SMI business models occur in complex, even collective (co-)production and (co-)consumption settings. This co-creation involves several stakeholders, involves mutual vetting by potential partners and is characterized by significant transaction costs. The scalability of SMI business models is limited due to the core value proposition (the SMI persona and contents), space and time constraints as well as by increasing efforts to sustain parasocial relationships with audiences. Due to the personalised nature of the value proposition, the intertemporal stability of business models is uncertain. The study enlarges the understanding of competition within platform-based ecosystems by looking at complementors with limited resources and scaling ability. It also sheds light on digital business models from a service-dominant logic perspective

My blogger told me it was okay : processing and persuasion of youth risk behavior via parasocial interaction and health beliefs /

Includes vita.This study explored how parasocial interaction (PSI) and health beliefs influence motivational processing of blog content among young women using a 2 (Stance: Anti, Pro) X 4 (Risk Behavior: E-Cigarette, Drinking, Product, Control) X 2 (Order) X 60 (Seconds) mixed factorial design experiment (N = 63). Using the theoretical frameworks of the terror management health model (TMHM) and the health belief model (HBM), the study predicted the effects of parasocial interaction, such that a higher level of parasocial interaction (PSI) the viewer experienced before exposure to the stimuli would lead to increased emotional response, attention and physiological arousal. Among other findings, participants with higher PSI for a beauty blogger had greater reported positive emotional response toward blog posts than those with lower PSI. Additionally, those with higher PSI reported the greatest self-reported positive emotion toward product, news, and video posts (control condition in this study), suggesting that a higher level of PSI led individuals to be more engaged with self-goals (vs. health-goals) within the TMHM. HBM variables (i.e., susceptibility, severity, barriers, and benefits) were also found to predict participants' PSI response, emotional response, physiological arousal, and attention.Dr. Glen Cameron, Dissertation Co-Supervisor.|Dr. Sungkyoung Lee, Dissertation Co-Supervisor|Includes vita.Includes bibliographical references (pages 79-87)

Storytelling to Promote Mental Health: A Conceptual Analysis and Application with Acceptance and Commitment Therapy for Depression

Mental health treatments can be delivered in many ways. One approach is to use storytelling to communicate healthy practices. While societies across the world have engaged in storytelling for thousands of years, these practices have been used less in the mental health field. The aim of this project was to study the overlap between the areas of mental health and storytelling. We also tested how a storytelling-based mental health treatment could help solve a particular clinical problem. In this case, the problem of people who receive inadequate help for managing depression through medication alone. We examined one particular mental health intervention, called Acceptance and Commitment Therapy (ACT), and its overlap with basic principles of storytelling. The central goal of ACT is to live more fully according to one’s personal values even in the presence of emotional suffering. We explain technically how reading, hearing, or seeing engaging stories could support this goal. We also describe ways that therapists who use ACT with their patients can draw from these storytelling-based principles. The second part of this project was a specific test of what happens when ACT and storytelling are combined in a mental health treatment. LifeStories is an online mental health program that teaches ACT-based skills for managing depression through the use of personal narrative videos of other patients who have developed effective ways of coping. We tested LifeStories with a group of primary care patients who were prescribed vi antidepressant medication but were not receiving other mental health support. Half of these patients used the LifeStories program for four weeks in addition to taking their medication, while the other half only took medication. We found that patients who used LifeStories had greater increases in quality of life compared to those only taking medication. These patients also became more interested in continuing mental health treatment after the program ended. In both groups of patients, depression severity decreased at the same rate, as did psychological inflexibility. Overall, our study showed that a brief storytelling intervention can improve quality of life and promote interest in seeking further mental health support for primary care patients

Evaluating the relative effectiveness of utilitarian and existence value appeals for promoting ecocentric concern and pro-environmental behavior

Pro-environmental behavior has been linked in many studies to attachment to the natural world, often conceptualized as ecocentrism. The current study sought to explore whether environmental PSAs employing an existence value--as opposed to a utilitarian (usually cost-based)--frame might contribute to a more ecocentric mindset. Secondary goals of the study were to determine whether existence value frames might positively influence intention toward conducting pro-environmental behaviors, as well as whether those who are more egoistically oriented might be more receptive to utilitarian messages. The experimental approach presented participants with a randomly selected pro-environmental PSA representing either an existence value or utilitarian frame. Results from the main study indicate that a utilitarian frame can have a negative impact on both ecocentrism and pro-environmental behavioral intention, and that high-egoism participants were not more persuaded by utilitarian approaches

The clinical effectiveness of individual behaviour change interventions to reduce risky sexual behaviour after a negative human immunodeficiency virus test in men who have sex with men: systematic and realist reviews and intervention development

Background: Men who have sex with men (MSM) experience significant inequalities in health and well-being. They are the group in the UK at the highest risk of acquiring a human immunodeficiency virus (HIV) infection. Guidance relating to both HIV infection prevention, in general, and individual-level behaviour change interventions, in particular, is very limited. Objectives: To conduct an evidence synthesis of the clinical effectiveness of behaviour change interventions to reduce risky sexual behaviour among MSM after a negative HIV infection test. To identify effective components within interventions in reducing HIV risk-related behaviours and develop a candidate intervention. To host expert events addressing the implementation and optimisation of a candidate intervention. Data sources: All major electronic databases (British Education Index, BioMed Central, Cumulative Index to Nursing and Allied Health Literature, EMBASE, Educational Resource Index and Abstracts, Health and Medical Complete, MEDLINE, PsycARTICLES, PsycINFO, PubMed and Social Science Citation Index) were searched between January 2000 and December 2014. Review methods: A systematic review of the clinical effectiveness of individual behaviour change interventions was conducted. Interventions were examined using the behaviour change technique (BCT) taxonomy, theory coding assessment, mode of delivery and proximity to HIV infection testing. Data were summarised in narrative review and, when appropriate, meta-analysis was carried out. Supplemental analyses for the development of the candidate intervention focused on post hoc realist review method, the assessment of the sequential delivery and content of intervention components, and the social and historical context of primary studies. Expert panels reviewed the candidate intervention for issues of implementation and optimisation. Results: Overall, trials included in this review (n = 10) demonstrated that individual-level behaviour change interventions are effective in reducing key HIV infection risk-related behaviours. However, there was considerable clinical and methodological heterogeneity among the trials. Exploratory meta-analysis showed a statistically significant reduction in behaviours associated with high risk of HIV transmission (risk ratio 0.75, 95% confidence interval 0.62 to 0.91). Additional stratified analyses suggested that effectiveness may be enhanced through face-to-face contact immediately after testing, and that theory-based content and BCTs drawn from ‘goals and planning’ and ‘identity’ groups are important. All evidence collated in the review was synthesised to develop a candidate intervention. Experts highlighted overall acceptability of the intervention and outlined key ways that the candidate intervention could be optimised to enhance UK implementation. Limitations: There was a limited number of primary studies. All were from outside the UK and were subject to considerable clinical, methodological and statistical heterogeneity. The findings of the meta-analysis must therefore be treated with caution. The lack of detailed intervention manuals limited the assessment of intervention content, delivery and fidelity. Conclusions: Evidence regarding the effectiveness of behaviour change interventions suggests that they are effective in changing behaviour associated with HIV transmission. Exploratory stratified meta-analyses suggested that interventions should be delivered face to face and immediately after testing. There are uncertainties around the generalisability of these findings to the UK setting. However, UK experts found the intervention acceptable and provided ways of optimising the candidate intervention. Future work: There is a need for well-designed, UK-based trials of individual behaviour change interventions that clearly articulate intervention content and demonstrate intervention fidelity

Consumption breakdowns:On avoiding and embracing temptations

Self-regulation is a complex process that involves consumers’ persistence, strength, motivation, and commitment in order to be able to override short-term impulses. In order to be able to pursue their long-term goals, consumers typically need to forgo immediate pleasurable experiences that are detrimental to reach their overarching goals. Although this sometimes involves resisting to simple and small temptations, it is not always easy, since the lure of momentary temptations is pervasive. In addition, consumers’ beliefs play an important role determining strategies and behaviors that consumers consider acceptable to engage in, affecting how they act and plan actions to attain their goals. This dissertation investigates adequacy of some beliefs typically shared by consumers about the appropriate behaviors to exert self-regulation, analyzing to what extent these indeed contribute to the enhancement of consumers’ ability to exert self-regulation.
