Abstract
Purpose
This study aims to propose a rapid optimization design framework for the electric propulsion system of tiltrotor aircraft with a comprehensive set of propeller and motor parameters.
Design/methodology/approach
To enhance the prediction accuracy, the authors have developed correction models for both the propeller and motor, i.e. the propeller performance model is based on blade element momentum theory, with the Reynolds-averaged Navier–Stokes method to obtain blade airfoil aerodynamic data, and the motor performance model incorporates an experimentally corrected second-order equivalent circuit model. Using Bayesian optimization algorithms, the authors have addressed the mixed-integer nonlinear programming design problem, which includes discrete variables such as the number of propeller blades and blade airfoil type, as well as continuous variables such as propeller diameter, pitch angle, chord length distribution, twist angle distribution, initial motor resistance, no-load current and KV value.
Findings
To estimate the aircraft-level performance, the authors have integrated the electric propulsion system into the tiltrotor’s overall mission profile, where an energy consumption reduction of 34.1% for the mission profile can be achieved after propeller and motor simultaneous optimization.
Originality/value
This study provides a valuable tool for the preliminary design and optimization of the electric propulsion systems for tiltrotor aircraft.

Abstract
This chapter reflects on a media studies project exploring Sylvia Plath poetry on Tumblr. The project ultimately resulted in excess digital data, with no conventional publications or research outputs. Now writing 10 years after data collection, I take a storying approach to explore the original research concerns and the research process, thereby locating a reconfigured ‘research event’ that draws together various biographical, social, political and historical factors. I reflect on my evolving understanding of ‘research’, discussing early teaching experiences and postgraduate pathways that partly structured a particular relationship to research. This serves to bridge a discussion about the challenges of the initial process over a decade ago, including the uncomfortable pairing of inexperience among aspiring researchers and institutional pressures to publish. I then discuss the theoretical perspectives that inspire and, in retrospect, offer clarity for the project, given the amount of time passed since data collection and the synergistic relationship between the storying approach, poststructuralist thought and story-focused methodologies. I argue that Tumblr provides unique opportunities for identity negotiation, aesthetic appreciation, data extraction and commodification, which highlights both the creative agency of digital aesthetic curation and self-work, as well as the importance of algorithmic transparency. I also contend that engaging with excess data led to methodologically and theoretically useful insights, challenging assumptions about the temporality of usable data and the ever-changing relationship between art, technology and freedom.

Abstract
Purpose
This study aims to analyse the influence of football fans' involvement on sponsor brand equity and their purchase intention toward the sponsoring brand. To achieve this, we specified a structural model examining the relationships between engagement, brand equity and fans’ purchase intentions.
Design/methodology/approach
The data for this study were collected using a structured questionnaire. Three football teams from the city of Quito (Ecuador) that compete in the first division of Ecuadorian professional football were considered. For data collection, both personal interviews and a web link were used. The personal interviews were carried out directly with the fans of the three teams in the vicinity of the stadiums, prior to matches of the Ecuadorian League.
Findings
The study concluded that a greater involvement of fans with a football club positively influences both the valuation of the sponsoring brand and the intention to purchase the product and/or service of the sponsoring brand.
Practical implications
This work contributes to the literature on brand equity. On the one hand, from the companies’ perspective, it is important for brand managers to realise that football fans constitute an especially significant section of the public to strengthen the brand and even to buy the products of the sponsoring brand. On the other hand, from the point of view of the clubs, it should be borne in mind that the involvement of the fans with the clubs constitutes a major factor in strengthening the sponsoring brands.
Originality/value
Most of the research in the literature has studied purchase intention towards the club brand but not towards the sponsoring brand. The research, which is applied to the football industry, conceptually extends the customer-based brand equity (CBBE) model by including the perspective of football fans’ involvement with their clubs.

Abstract
Purpose
This study aims at building a framework for the electronic word-of-mouth (eWOM) response under the social media environment. The elaboration likelihood model was adopted to explain how message source credibility and message appeal jointly influence the eWOM response process, while source credibility provides a central route and message appeal plays a peripheral route for information processing.
Design/methodology/approach
This study used a scenario design to test the decision behavior in the Facebook environment through message content manipulation. A convenience sampling method was adopted in this study. We collected 203 valid questionnaires and tested this research model with LISREL 8.8. This study used a two-stage structural equation modeling data analysis method with LISREL 8.8, by which the measurement model was assessed through confirmatory factor analysis for the reliability and validity of the research model, and the causal relationship among factors was assessed through exploratory factor analysis .
Findings
The results showed that 53% variance of eWOM responses could be explained by message source credibility and emotional message appeal from the elaboration likelihood model perspective. Message source credibility plays a central role in the social media environment. The model was further tested with a demographic profile analysis for both gender and age. It is found that a female user is influenced by both source credibility and emotional appeal, but a male user is only influenced by message source credibility. The mature age group is more responsive to eWOM messages.
Research limitations/implications
The sample might not represent all social networking sites (SNS) users. The participants represent a small segment of the Facebook population around the globe. Secondly, this research design could be improved by using more recreational messages to test the effects of message appeal and message source credibility. Thirdly, the mobile phone is a type of physical product rather than an experiential product. Future studies could try to identify the same eWOM determinants with different SNS functions, for example, the inbox message function. Similarly, Facebook users are allowed to use both text and pictures to disseminate promotional messages.
Practical implications
This study provides an insight for SNS administrators regarding the determinants of driving more customer responses toward a message. Message source credibility and message appeal are identified as the antecedents for eWOM responses in SNS. Companies could make use of this finding to improve their marketing communication strategy in SNS. The finding can inform administrators of the importance of focusing on both customers’ psychological state and message attributes during the dissemination of promotional messages to improve the efficiency of the promotional effort. Companies aimed at receiving different types of eWOM responses in SNS may need to consider other factors for creating their promotional messages.
Originality/value
Previous studies have mainly identified factors influencing eWOM responses from the people-centered variables such as personal traits and social relationships. This study proposes that the eWOM response is a dual information processing process that can be explained by the ELM. When a user processes information in SNS, he follows both the central route and the peripheral route (i.e. source credibility and message appeal) which can influence the eWOM response. It is the first time that the source credibility is investigated as the central route in ELM model.

Abstract
Purpose
In Belgium, mentally ill offenders often spend extended periods in forensic psychiatric hospitals, where restrictive living conditions can affect their quality of life (QoL). QoL is a key factor in these settings, influencing both short- and long-term recidivism risks. Despite its significance, research on QoL in Belgian forensic psychiatry is scarce. Internationally, studies highlight that the sexuality domain tends to score lower than other QoL areas. This study aims to explore QoL in forensic psychiatry with a particular focus on the sexuality domain.
Design/methodology/approach
This cross-sectional, observational study involved 275 male forensic psychiatric patients, all found not guilty by reason of insanity and under court-ordered psychiatric treatment. Patients resided in either treatment units or long-term forensic care units. Data were analyzed using R Studio.
Findings
Patients in medium-security units in Flanders reported the lowest satisfaction in the sexuality domain compared to other QoL areas. Additionally, overall QoL declined with longer stays in forensic psychiatric care.
Practical implications
The study underscores the need for clear policies regarding sexuality in forensic psychiatric settings. Integrating sexuality and sexual health assessments into routine evaluations is recommended. Future research should explore long-term QoL changes while investigating the impact of sexuality policies and considering gender and cultural differences. Collaboration between forensic institutions is key to improving data collection, while staff training on addressing sexuality is essential. Including patients in policy development and promoting their sexual health rights will help create a more inclusive environment.
Originality/value
To the best of the authors’ knowledge, this is the first study to pool data from three forensic medium-security units in Flanders, providing new insights into QoL in Belgian forensic psychiatry.

Abstract
Purpose
Increased work hours can result in stress and burnout among mine workers. Research within stone, sand and gravel mining operations is limited and has not explored whether health impairment, in this context, influences job satisfaction and turnover intention among these workers.
Design/methodology/approach
A path analysis was completed using Mplus to assess a theoretical model and hypotheses associated with model variables to include work hours, stress, burnout, job satisfaction and turnover intention. Cross-sectional survey data from 419 stone, sand and gravel mine workers were used in the path analysis.
Findings
Model fit was good. Work hours were positively associated with stress, stress was positively associated with burnout, stress and burnout were negatively associated with job satisfaction, stress and burnout were positively associated with turnover intention and job satisfaction was negatively associated with turnover intention. Burnout partially mediated the relationship between stress and both job satisfaction and turnover intention. Job satisfaction partially mediated the relationship between stress and turnover intention and burnout and turnover intention. An alternate model determined there was no direct relationship between work hours and burnout and that this relationship was fully mediated by stress.
Originality/value
Findings illustrate the importance of managing work hours among mine workers to reduce health impairment and to bolster job satisfaction and reduce turnover intention.

Abstract
Purpose
How to reduce uncertainty in clothing online purchasing has become a primary concern for consumers. This study aims to investigate the effects of quality perception and multisensory perception on consumer online clothing purchase intention and to explore the mediating effect of trust.
Design/methodology/approach
This study was conducted with consumers who have online clothing shopping experiences. A total of 539 valid samples were analyzed by bootstrap and structural equation model.
Findings
The result of this research revealed that perceived information quality, perceived service quality, perceived haptic imagery and perceived visual-audio cues have a significant influence on purchase intention. Additionally, consumers’ trust is positively correlated with purchase intention. Trust mediates the relationship between the perceptions (perceived information quality, perceived service quality, perceived haptic imagery and perceived visual-audio cues) and purchase intention, irrespectively.
Originality/value
To investigate the effects of multisensory perception on purchase intention, perceived haptic imagery is adopted as a variable in this study. This study investigates the mediating role of trust between multisensory perception and purchase intention. The findings of this study can enrich Stimulus-Organism-Response (S-O-R) framework and Information System (IS) success model in the field of clothing online shopping.

Abstract
Purpose
Loading the work on social capital theory, we have tried to check the influence of social currency (SC) on social media usage (SMU) and its subsequent impact on the brand experience (BE). The study attempted to ascertain the mediation of loyalty (LT) between the SC and SMU as well as the moderation of perceived ease of use (PEU) in the SMU and BE relationship.
Design/methodology/approach
The data were collected from 384 respondents employing snowball sampling technique by administering a questionnaire on seven-point Likert scale. The respondents were the active internet users, who devote the significant part of their daily routine to social media activities. Structural equation modelling was used to study the path of the considered variables.
Findings
The result of the study strengthened the findings of earlier studies on SC dimensions. This study elaborated about the positive impact of SC on SMU, SC on LT, LT on SMU, SMU on BE. The study also found the mediating effect of LT in the SC and BE relationship. The study did not identify a moderating role of PEU in the SMU and BE relationship.
Research limitations/implications
By taking into account SC, SMU, LT, PEU and BE, the study adds the knowledge to the social capital theory.
Practical implications
This study aids marketers in adjusting social media strategies for the effective use of SC aimed to deliver enhanced BE. Additionally, it demonstrates the value of customer LT in the context of SC and SMU by customers.
Originality/value
This study is among the few research on the SC of the Indian user and its impact on SMU and BE. Checking the mediation of LT and the moderation of PEU in the SC context makes this study novel and different from any study conducted earlier.

Abstract
Purpose
This study aims to establish whether three technology-specific attributes – convenience, compatibility with cultural needs and social reputation – influence the sustained use of clean cooking technologies in Uganda’s households.
Design/methodology/approach
This study adopted a cross-sectional and correlational research design. A survey was conducted with 125 households. The data were analyzed using SPSS and Smart PLS.
Findings
The results indicate that, in contrast to convenience, social reputation and compatibility with cultural needs significantly influence the sustained use of clean cooking technologies in Uganda’s households.
Research limitations/implications
This study focused on the Greater Kampala Metropolitan Area; hence, several households in other urban centers and rural communities were excluded from the study. In addition, technology-specific attributes only accounted for 34.4% of the variation in the sustained use of clean cooking technologies in Uganda, leaving 65.6 unexplained. Therefore, the authors recommend that future studies look at other technology-specific attributes that may influence the sustained use of clean cooking technologies in Uganda’s households.
Originality/value
This study provides initial evidence of technology-specific attributes and the sustained use of clean cooking technologies based on the expectation–confirmation model.

Abstract
Purpose
Through the lens of resource-based view (RBV), knowledge-based view (KBV) and DCV, this paper aims to investigate the relationship of entrepreneurial leadership (EL) on the project success (PS) and further examines the mediating effect of knowledge infrastructure capability (KIC), knowledge-based dynamic capability (KBDC) and Big data analytic capability (BDAC).
Design/methodology/approach
The data were collected from 467 employees working on project in software companies. The data were evaluated using SMART-PLS, a structural equation modeling (SEM) tool.
Findings
The study revealed a significant impact of EL on the PS, the study also found the significant mediation role of KIC, KBDC and BDAC on the EL and PS relationship.
Originality/value
The research gives valuable insight into the effective role of EL as a contemporary leadership style in project-based firms. Also, this research is one of the first to examine knowledge-oriented dynamic capabilities (DC) as a knowledge fulcrum in project execution. These DC have been empirically proven to facilitate EL in achieving PS and support the firm in competing in an uncertain environment.
