This paper aims to focus on the design, analysis and additive manufacturing (AM) with two different technologies of an accelerator pedal for the Formula Student 2014 edition to reduce the weight of the original pedal in aluminium and maintain a reasonable level of performance.

The new and the original accelerator pedals were modelled in a computer-aided design application, and three finite element simulations were performed for each manufacturing technology to evaluate three different driving scenarios. Later on, two physical prototypes were manufactured using two AM technologies: poly-jet and fused deposition modelling (FDM). With these physical prototypes, static tests were carried out to verify the computational simulations and to determine the fracture load, while dynamic tests, based on an input signal from a real racing scenario, were performed to ensure their technical viability.

Simulations with poly-jet and FDM printing material show that the new design presents a maximum deformation of 4.8 and 4.09 mm, respectively, under a nominal load of 150N. The results of the static tests with the poly-jet physical prototype showed a maximum displacement of 4.05 mm under a nominal load of 150N, while the ultimate load before fracture was 450N. The FDM prototype reached 3.98 mm under 150N and the ultimate load was 350N. Dynamic tests showed that both pedals were able to withstand four Formula Student “Endurance” events without failure.

This paper states that AM approach is a feasible and economically affordable solution in comparison to exiting solutions with metallic alloys and composite materials when designing and manufacturing accelerator pedal arms for Formula Student competition cars. According to these results, the present research argues that, from a technical point of view, the AM pedals stand at a reasonable level of performance in displacements and stresses. This study suggests that AM pedals could be a viable option that must be considered in professional competitive automobiles.

The struggle against torture and institutional violence has to be practiced in numerous scenarios: in the very places of deprivation of liberty, against workers, administrations and judges who try to hide it or justify it, but also, it’s a struggle against an academy that, too often, has decided to look the other way. In order to be activist, criminology must leave the classroom and enter the places of deprivation of liberty. It must engage with victims and survivors and it has to make political and social denunciations, organising itself and weaving networks with other social organisations that fight for the same goal. Unfortunately, it also has to fight against the very obstacles that the criminal justice system institutions pose; the denunciations and persecution of these same institutions and some police and prison workers groups and unions; the dirty war against terrorism and political dissent; and the criminalisation of some mass media and also of the academic world, where activism against this phenomenon is a minority and marginalised. These two sides of the same coin, involvement in anti-torture activist movements, as well as persecution and criminalisation when challenging state power, is what the authors of this chapter have experienced in Catalonia and Spain. While we fight against torture outside the classroom, we also carry out activism inside the classroom, teaching what other academics do not want to engage with, and pointing out the political elements of criminology and the action of the penal system. In this chapter, the authors highlight the use of torture and other cruel, inhuman or degrading treatment or punishment in custody and prison, and in the context of police activity in Spain. Then, the authors explain the structures of denial (political, judicial and academic) that allow its perpetuation and impunity. The text ends with a journey through the configuration of activist criminology in Spain that unites critical analysis from a legal sociology perspective with collective and activist intervention.

This study aimed to determine whether the brand image of fast-food restaurants moderates the relationship between satisfaction and loyalty among Chilean customers.

The study was conducted using a structural equation modeling approach and involved a sample of 1,000 fast-food customers who were surveyed through nonprobabilistic sampling with a questionnaire consisting of 21 items. The instrument underwent validation by a panel of experts, and the results obtained were processed using the statistical software Smart PLS4. Convergent validity, discriminant validity and the structural model were tested to assess the acceptance or rejection of the proposed hypotheses.

The results of the research indicate that product quality, service quality and physical environment are crucial factors influencing customer satisfaction and shaping customer loyalty. However, it was found that brand image does not moderate the relationship between satisfaction and loyalty in fast-food consumption.

The present study contributes to the field of knowledge on fast-food consumption behavior and unveils findings that help fill knowledge gaps regarding the influence of restaurant brand image on the relationship between satisfaction and consumption loyalty. Thus, it demonstrates that, for certain customers, the brand becomes an irrelevant factor for their consumption loyalty as long as the restaurant offers product quality, excellent service and a pleasant physical environment.

Around 50 per cent of carers of people with eating disorders (EDs) experience mental health difficulties. The purpose of this paper is to investigate well-being of carers of people with ED and carers of people with severe and enduring eating disorders (SEEDs).

Carers (n=104) were recruited from UK support groups and stratified using duration of the care recipient’s ED (0-2, 2-6, > 6 years), with the > 6 years category classified as SEED. Data were compared with existing carer well-being studies of other patient groups.

Carers of people with SEED were not significantly different on reported well-being to carers of people with ED. However, carers of people with ED reported significantly less well-being than community norms, carers of people with brain injury and of people with dementia. Specifically, poorer social functioning was reported.

Further research on carers of people with SEED is warranted as carers of people with SEED were not equally balanced in gender. It would be beneficial if support groups and skill-based workshops were more available for carers.

This is the first known study to compare carer well-being of people with SEED with carers of other clinical populations. Further research is required to identify the needs of carers.

This study aims to identify how Spanish consumers’ extrinsic preferences for food have evolved by examining the extant literature on food preferences in Spain, focusing on food-related attributes and food-related values.

This study is based on a synthetic review of the extant academic literature on Spanish consumer preferences for food-related attributes and food-related values from the mid-20th to the 21st century. This study uses key economic and social milestones that are most likely to influence food value chain actors to show how consumer preferences have evolved over the study period.

Spanish consumer food attribute preferences expanded as the food sector of the nation continued to grow, and value preferences showed a similar pattern from the mid-20th to the 21st century. The drivers of these preferences were trust, lifestyle, education (campaigns), sociodemographic factors and purchasing power.

Evaluating the extant literature’s contribution to consumer preferences for food-related attributes and values is important because it can aid in understanding the hierarchy and variety of consumers’ food preferences as well as the factors that drive these preferences. To the best of the authors’ knowledge, this study is the first to explore how Spanish consumer preferences evolved between the mid-20th and 21st centuries.

Given the potential for authorial fashion to lead the way in the field of sustainable fashion and digital platforms to be a powerful tool for spreading sustainable messages, this study seeks to explore the emphasis given to sustainability in the digital communication of Portuguese and Spanish’s authorial fashion.

A thematic analysis of all the posts published on the feeds of the 63 designers who presented their collections at the Madrid and Lisbon fashion weeks in September/October 2022 (Spring/Summer 2023) or February/March 2023 (Fall/Winter 2023/2024) editions was carried out. The information was collected over a six-month period between the two fashion weeks. This study is based on the categories identified in the reflexive thematic analysis developed by Testa et al. (2020). After adapting the categories to our analysis, 14 emerging themes were identified as observation criteria.

A total of 4,699 posts were examined. The analysis reveals a general lack of interest in mentioning sustainability – a subject evident in just around 6% of the content – as well as a high emphasis on the visual aspect of the fashion product. Several similarities between the Portuguese and Spanish markets were observed.

This study is important since there are few cross-cultural studies in the field of fashion between the two countries, particularly on sustainable fashion. Furthermore, it establishes a structure that is easily replicable in various markets and geographical areas.

The content of training (art-based method) and instructional strategies (blended learning) can improve business school students' creativity and attempts to determine how training can be maintained using longitudinal tracking. The study aims to answer (1) whether the incorporation of art-based methods enhances the creativity of students compared to traditional face-to-face (F2F) teaching, and (2) whether such creative training and blended teaching methods have a higher transfer of training.

This study adopted a two-stage design (1) it adopted a 2 × 2 (with or without art-based methods * blended teaching or F2F teaching) between-subject design of experiments with 221 participants and (2) a one-year follow-up study was conducted (participants who were employed for 6 months to one year after graduation) with 187 participants and their directors.

The results showed that the inclusion of art-based methods in the creative training of students strengthens creative ability of the students; there were no significant differences between blended and traditional learning. The authors examined the effect of transferring creative training through a questionnaire analysis of participants and employers of the participants. Self-regulated and self-directed learning positively influence motivation to transfer, which positively influences creative performance.

The higher the level of self-regulated and self-directed learning of students, the more effective the transfer of creative training is over time.
