Published: December 2021

AbstractSKD3, also known as human CLPB, belongs to the AAA+ family of ATPases associated with various activities. Mutations in the SKD3/CLPB gene cause 3-methylglutaconic aciduria type VII and congenital neutropenia. SKD3 is upregulated in acute myeloid leukemia, where it contributes to anti-cancer drug resistance. SKD3 resides in the mitochondrial intermembrane space, where it forms ATP-dependent high-molecular weight complexes, but its biological function and mechanistic links to the clinical phenotypes are currently unknown. Using sedimentation equilibrium and dynamic light scattering, we show that SKD3 is monomeric at low protein concentration in the absence of nucleotides, but it forms oligomers at higher protein concentration or in the presence of adenine nucleotides. The apparent molecular weight of the nucleotide-bound SKD3 is consistent with self-association of 12 monomers. Image-class analysis and averaging from negative-stain electron microscopy (EM) of SKD3 in the ATP-bound state visualized cylinder-shaped particles with an open central channel along the cylinder axis. The dimensions of the EM-visualized particle suggest that the SKD3 dodecamer is formed by association of two hexameric rings. While hexameric structure has been often observed among AAA+ ATPases, a double-hexamer sandwich found for SKD3 appears uncommon within this protein family. A functional significance of the non-canonical structure of SKD3 remains to be determined.
Emotion transformation: a grounded theory for uncovering painful triggers and repairing relational connection for parents of autistic children
Authors: Robinson Anna , Yong Ennie 
Published: December 2021

Purpose
It is often voiced that parents of autistic children are the expert of their child, whereas parenting programmes target them as effective mediators for change. This paper aims to explore this unchallenged heuristic to develop an understanding of both emotional and relational needs of parents through trainers’ experiences of delivering emotion-focused and autism parent training.

Design/methodology/approach
This qualitative study used a constructivist approach of grounded theory to gain an in-depth understanding of trainers’ experiences from their encounters when delivering parent training. Six expert trainers were interviewed, and a two-phased coding of ground theory and an adapted thematic analysis was used.

Findings
An overarching theme emerged: emotion transformation from painful triggers, to enhanced attunement and relational repair. Four main themes containing 13 subthemes were identified. The interaction of these themes and subthemes are presented in a three-phase process model. Phase 1: uncovering painful emotions from a shared journey contained one theme: parent painful triggers. Phase 2: uncovering interpersonal rupture cycle contained one theme: relational rupture cycle within non-synchrony of attunement. Phase 3: parent–child relational repair contained two themes: repairing attachment bonds and therapist’s prizing stance.

Social implications
The authors challenge the parent as expert heuristic and propose that not all parents feel expert in neurotypical-neurodivergent intersubjectivity. The authors are curious to see whether trainers/therapists can guide parents through unprocessed emotions and non-synchrony of attunement to promote healing and relational repair, which requires further investigation.

Originality/value
To the best of the authors’ knowledge, this is the first emotion-transformation process model grounded in humanistic principles of relational acceptance and emotion theory. The authors propose that a focus on process rather than outcome is more likely to result in higher parenting self-efficacy.
How preexisting beliefs and message involvement drive charitable donations: an integrated model
Authors: Van Steenburg Eric , Spears Nancy 
Published: December 2021

PurposeThe purpose of this paper is to investigate how individuals respond to messages asking for donations in broadcast advertising. It does so by considering both preexisting attitudes and beliefs related to donating, as well as message processing. The goal is to uncover messages that may help nonprofit organisations increase donations.Design/methodology/approachThe research combines the theory of planned behaviour (TPB) to measure preexisting beliefs and the elaboration likelihood model (ELM) to measure involvement in an investigation of donation responses to broadcast-quality advertisements developed by a professional ad agency featuring the following two messages: one that leverages social norms and another that legitimises minimal giving. Two studies collected data from a total of 544 respondents in two between-subjects 2 × 2 × 2 experiments.FindingsInjunctive norm messages affect the intended donation behaviour of individuals who are pre-disposed to donating, but only if they are highly involved with the ad. Social legitimisation messages affect donations from individuals who look to referents to direct behaviour, but unlike what was expected, only by those not highly involved with the ad. Similarly, individuals who do not think they can donate increased donations when they saw the legitimisation message and had low advertisement involvement.Research limitations/implicationsResults extend the ELM-TPB integrated framework by discovering when and how involvement drives intended donation behaviour. The research also sheds light on message processing by focussing on the preexisting characteristics of recipients.Practical implicationsThe results provide nonprofit managers with strategies to increase donations with targeted messages. Those who pay attention to the ad and have a positive attitude toward giving are going to donate if they are told others support the cause. Therefore, the focus should be on those who are not involved with the ad but still believe giving is appropriate.Originality/valueThis research is the first to use the ELM-TPB framework to discover that ELM has varying utilities and values from TPB in different ad contexts.
A study of a modified nonlinear dynamical system with fractal-fractional derivative
Authors: Kumar Sunil , Chauhan R.P. , Momani Shaher , Hadid Samir 
Published: December 2021

Purpose
This paper aims to study the complex behavior of a dynamical system using fractional and fractal-fractional (FF) derivative operators. The non-classical derivatives are extremely useful for investigating the hidden behavior of the systems. The Atangana–Baleanu (AB) and Caputo–Fabrizio (CF) derivatives are considered for the fractional structure of the model. Further, to add more complexity, the authors have taken the system with a CF fractal-fractional derivative having an exponential kernel. The active control technique is also considered for chaos control.

Design/methodology/approach
The systems under consideration are solved numerically. The authors show the Adams-type predictor-corrector scheme for the AB model and the Adams–Bashforth scheme for the CF model. The convergence and stability results are given for the numerical scheme. A numerical scheme for the FF model is also presented. Further, an active control scheme is used for chaos control and synchronization of the systems.

Findings
Simulations of the obtained solutions are displayed via graphics. The proposed system exhibits a very complex phenomenon known as chaos. The importance of the fractional and fractal order can be seen in the presented graphics. Furthermore, chaos control and synchronization between two identical fractional-order systems are achieved.

Originality/value
This paper mentioned the complex behavior of a dynamical system with fractional and fractal-fractional operators. Chaos control and synchronization using active control are also described.

Authors: Lajante Mathieu , Ladhari Riadh , Massa Elodie 
Published: December 2021

PurposeResearch on the role of affective forecasting in hotel service experiences is in its infancy, and several crucial questions remain unanswered. This study aims to posit that affective forecasting is a significant antecedent of customers’ affective reactions during a hotel stay. The authors investigate how customers’ service quality expectations influence their affective forecasting and how customers’ affective forecasting before an upcoming hotel service experience influences their affective reactions during the hotel service experience.Design/methodology/approachThe authors collected data through online questionnaires distributed among 634 US adults who had stayed at a hotel within the past month.FindingsThe results show that: service quality expectations influence affective forecasting; affective forecasting influences affective reactions; service quality expectations influence perceived service quality, thereby influencing affective reactions and affective reactions and service quality perception influence electronic Word-Of-Mouth intentions.Practical implicationsThe study suggests that hotel managers should identify what hotel performance attributes customers value most and depict how these attributes elicit positive affective reactions in advertising to influence customers’ purchase decisions.Originality/valueThis is one of the few studies to investigate the antecedents and consequences of affective forecasting in hotel service experiences.

Innovation for environmental sustainability: longitudinal effects of an education for sustainable development intervention on university students’ pro-environmentalism
Authors: Collado Silvia , Moreno José David , Martín-Albo José 
Published: December 2021

PurposeAlthough education for sustainable development (ESD) is a key tool in the transition to a more sustainable society, its integration in higher education remains scarce. One reason for this is that more evidence is needed about the effectiveness of ESD interventions. This study aims to address this gap in the literature by examining the immediate and long-term effects of an ESD intervention on university students’ pro-environmental knowledge, personal environmental norm and pro-environmental behaviors.Design/methodology/approachThis study used a quasi-experimental design that examined to what extent participating in an ESD intervention influenced university students’ self-reported pro-environmentalism (i.e. experimental group), compared to those who did not participate in the ESD intervention (i.e. control group). The authors also examined the longitudinal effects of the ESD intervention by recording students’ pro-environmentalism (both in the experimental and control group) 1 year after the intervention.FindingsThe findings showed that participation in the ESD intervention enhanced students’ pro-environmental knowledge, personal environmental norms and pro-environmental behaviors relative to the no-participation control group. The positive effects of the ESD intervention remained 1 year after the program finished.Originality/valueThis work explores the effects that ESD interventions have on university students. Its findings provide evidence about the effectiveness of the intervention and, therefore, support the inclusion of ESD at higher educational levels.

Emotions in our lives: the evaluation of a user-centered training course »living e-Motions« in the context of recovery of people with mental health challenges
Authors: Bakračevič Karin , Zorjan Saša , Tement Sara , Christie Louise , Musil Bojan 
Published: December 2021

Purpose
This paper aims to evaluate the feasibility and effectiveness of a training course »Living e-Motions« for people living with mental health challenges in the context of their recovery. The course was developed in the joint project of partners from Spain, Estonia, Slovenia and the UK. The curriculum of the course is focused on emotional education. It uses a narrative approach as a practical way for participants to explore and regulate their emotions and consequently take charge of their recovery.

Design/methodology/approach
Seventeen participants were included in the pilot training in Spain and Estonia. Impact of the training was assessed on measures of life satisfaction, emotion regulation, positive and negative affect and recovery at baseline and directly after training.

Findings
The analysis revealed that participants reported higher life satisfaction, emotion regulation skills, positive affect and recovery after the training. However, because of the small sample size, the mean differences did not reach statistical significance. Further studies on larger samples are needed to test the effectiveness of the training course.

Practical implications
Pilot study findings are encouraging and show that the developed training course has a potential for improving key competencies and abilities needed in daily life, concretely in emotion regulation, positive and negative affect, life satisfaction and recovery.

Originality/value
This paper presents a novel training course that uses a narrative approach and focuses on recovery and improvement of key competencies and abilities of individuals with mental health issues.
End-to-end sustainability: trade-offs, consumers’ perceptions and decisions beyond B2C interfaces
Authors: Lee Park Camila , Fracarolli Nunes Mauro , Ishizaka Alessio 
Published: December 2021

Purpose
This study aims to examine the extended effects of corporate (ir)responsibilities in supply chains. More specifically, the authors compare the impact of social and environmental initiatives and failures in the reputational capital of supply chain partners. The authors investigate how (and if) companies’ decisions to prioritize different sustainability dimensions in their supplier selection processes (i.e. sustainability trade-offs) affect consumers’ perception of corporate image, corporate credibility-expertise, attitude towards the firm and word-of-mouth.

Design/methodology/approach
The authors conducted three behavioural vignette-based experiments with 562 participants from the USA, relying on analysis of variance and t-tests analyses.

Findings
Results show that consumers perceive social irresponsibility cases as more severe than environmental ones in suppliers’ operations, penalizing buyers’ corporate image, corporate credibility-expertise and word-of-mouth. Corporate image, attitude towards the firm and word-of-mouth also have significant differences between social and environmental trade-offs. Statistically significant differences were also found between scenarios that portrayed the discovery of an irresponsible action and ones that reinforced the previous irresponsible practice in companies’ suppliers.

Practical implications
When types of irresponsibility practices are presented, the discovery of child labour and modern slavery conditions in suppliers damage how consumers perceive the company on corporate image and their attitude towards the organization and how they will spread word-of-mouth, reinforcing the importance of considering sustainability issues when making supplier selection decisions.

Originality/value
The study contributes to the understanding of how companies are perceived by their consumers regarding irresponsible practices and their impact on firms’ supplier selection decisions. Furthermore, data suggests that consumers might hierarchize sustainability dimensions, perceiving social irresponsibility cases as more severe than environmental irresponsibility ones.
