Abstract
Purpose
Previous studies have mainly focused on the negative impact of illegitimate tasks on recipients but ignored its impact on observers. Drawing on deservingness theory, this research developed a moderated serial mediation model to examine the underlying mechanism in the relationship between observed illegitimate tasks and observers’ helping behaviour.
Design/methodology/approach
This research tested the model using a sample of 218 employees in China through a two-wave field study. A path analysis was conducted with the bootstrapping procedure to test the hypothesized model.
Findings
The results showed that the effect of observing illegitimate tasks was contingent upon the degree of the observer’s interpersonal liking towards the recipient. Specifically, when the observer had a high level of interpersonal liking for a coworker, the observer may perceive that the coworker was undeserving of being assigned illegitimate tasks, which increased sympathetic emotion and the sequent helping behaviour.
Originality/value
This study shifted the perspective of the illegitimate task literature from the recipient to the third parties. Additionally, it provided a finer-grained understanding of the mechanism between observed workplace disrespectful treatment and the observer’s helping behaviour.

Abstract
Purpose
The debate surrounding the influence of parental nutritional knowledge on offspring’s susceptibility to overweight/obesity persists, with a dearth of research elucidating the mechanisms involved. This study aims to explore if and how parental nutrition knowledge affects adolescents' overweight and obesity, by highlighting the mediating effect of parental perceived severity of obesity.
Design/methodology/approach
A questionnaire was conducted in Zhejiang Province, China, with a sample of 2,298 students as well as their parents during November–December 2022. Logistic regression and propensity score matching methods was used to validate the relationship between parental nutrition knowledge and adolescents' overweight/obesity, while the multiplication coefficient method was used to test the mediation effect.
Findings
Parental nutrition knowledge significantly reduces the odds ratio for adolescent obesity, without affecting the likelihood of overweight. The perceived severity of obesity fully mediates the relationship between parental nutrition knowledge and adolescents' overweight and obesity.
Research limitations/implications
By exploring mediating factors, the analysis offers an innovative explanation of the process by which nutritional knowledge influences health behaviors. Lack of relevant motivation or beliefs is an important reason for the failure of nutritional knowledge. If parents do not have sufficient awareness of the dangers of overweight or obesity, they will have inadequate motivation to apply nutritional knowledge in guiding dietary or exercise decisions. We also supplement the literature by demonstrating the health belief model in highlighting the mediating mechanism of perceived severity in the relationship between parental nutrition knowledge and adolescents' obesity.
Practical implications
Extending the research focus on subjective beliefs and cognitive motivation bears important policy implications for designing education campaigns to effectively restrain the obesity rate. Considering that many Chinese parents have insufficient awareness of the dangers of childhood overweight and obesity, even considering “chubby children” as symbols of “cuteness” and “health”. This can largely undermine their motivation to apply nutritional knowledge to restrain adolescents' overweight and obesity. Consequently, education campaigns, public health professionals and government agencies can be developed aiming to increase parental nutrition knowledge, especially on the hazards of obesity.
Social implications
With the prevalence of overweight and obesity among adolescents, it is critical to control students' weight and health. Families, especially parents, are vital to the physical and mental health of adolescents. This research confirmed that improving parental nutrition knowledge is necessary for maintaining a healthy weight for adolescents. Results also emphasized that the association between parental nutritional knowledge and adolescents' overweight or obesity was mediated by parental perceived severity. This indicates that interventions designed to enhance parental nutritional knowledge should pay more attention to strengthening parental cognition of and beliefs in obesity.
Originality/value
This paper added to the debate on the impact of parental nutritional knowledge on adolescent’s overweight and obesity. Based on the health belief model, it also identified a novel pathway and mechanism by highlighting the importance of subjective motivations and beliefs such as the perceived severity of obesity in influencing overweight/obesity. Conclusions bear important policy implications for designing education campaigns to effectively restrain the obesity rate.

Abstract
Purpose
Building on the core concept of anthropomorphism and the empathy-helping theory, this research aims to examine how product anthropomorphism and buyer usage intentions affect sellers’ pricing in second-hand markets as well as explore the psychological dynamics underlying these effects.
Design/methodology/approach
To test the hypotheses, a series of four experiments were conducted. Studies 1a (n = 140) and 1b (n = 140) employed a one-factor (product anthropomorphism: yes vs no) between-subject design and used chi-square analysis. Study 2 (n = 145) and Study 3 (n = 162) employed a 2 (usage intention: protective vs destructive) × 2 (product anthropomorphism: yes vs no) between-subject design and used two-way ANOVA and moderated mediation analysis.
Findings
The study found that even when potential buyers with destructive (vs protective) usage intentions offer higher prices, sellers of anthropomorphized (vs non-anthropomorphized) products are less willing to choose them (Studies 1a and 1b). When potential buyers express destructive (vs protective) usage intentions, sellers of anthropomorphized (vs non-anthropomorphized) products are less willing to offer discounts (Study 2), and the lowest price they are willing to accept is higher (Study 3). The level of perceived capacity for pain mediates these effects (Study 3).
Originality/value
These findings offer insights into the application of product anthropomorphism strategies and the second-hand transactions of used anthropomorphized products.

Abstract
Purpose
Mechanoreception is crucial for robotic planning and control applications, and for robotic fingers, mechanoreception is generally obtained through tactile sensors. As a new type of robotic finger, the soft finger also requires mechanoreception, like contact force and object stiffness. Unlike rigid fingers, soft fingers have elastic structures, meaning there is a connection between force and deformation of the soft fingers. It allows soft fingers to achieve mechanoreception without using tactile sensors. This study aims to provide a mechanoreception sensing scheme of the soft finger without any tactile sensors.
Design/methodology/approach
This research uses bending sensors to measure the actual bending state under force and calculates the virtual bending state under assumed no-load conditions using pressure sensors and statics model. The difference between the virtual and actual finger states is the finger deformation under load, and its product with the finger stiffness can be used to calculate the contact force. There are distinctions between the virtual and actual finger state change rates in the pressing process. The difference caused by the stiffness of different objects is different, which can be used to identify the object stiffness.
Findings
Contact force perception can achieve a detection accuracy of 0.117 N root mean square error within the range of 0–6 N contact force. The contact object stiffness perception has a detection average deviation of about 15%, and the detection standard deviation is 10% for low-stiffness objects and 20% for high-stiffness objects. It performs better at detecting the stiffness of low-stiffness objects, which is consistent with the sensory ability of human fingers.
Originality/value
This paper proposes a universal mechanoreception method for soft fingers that only uses indispensable bending and pressure sensors without tactile sensors. It helps to reduce the hardware complexity of soft robots. Meanwhile, the soft finger no longer needs to deploy the tactile sensor at the fingertip, which can benefit the optimization design of the fingertip structure without considering the complex sensor installation. On the other hand, this approach is no longer confined to adding components needed. It can fully use the soft robot body’s physical elasticity to convert sensor signals. Essentially, It treats the soft actuators as soft sensors.

Abstract
Purpose
The present study examines the impact of sustainable transitions on the energy and environmental efficiency (EEE) of nations across the developed and developing world. It studies the temporal shift in the share of renewable sources in energy generation. It also analyses the shift in the efficiency frontier of nations using data envelopment analysis (DEA). Further, it studies the macro-level drivers of EEE in the countries.
Design/methodology/approach
As the first step, we benchmark the EEE of the developed and developing nations using DEA. Subsequently, we look at the influence of institutional quality, human capital, R&D and knowledge systems on EEE, to develop a comprehensive understanding of the macro-level drivers of EEE.
Findings
Our analyses reveal that a country’s institutional quality, human capital and R&D are critical determinants of EEE. The results show that while human capital has a significant positive impact on EEE, R&D expenditure alone has no substantial impact. The findings also suggest that knowledge diffusion disperses best practices across nations and bridges EEE gaps.
Practical implications
Attempts to promote sustainable energy transitions and improve EEE have met with varying levels of success. The results of this study will provide a useful guideline for the governments to achieve the goal of EEE through sustainable energy transitions (SET).
Originality/value
Unlike previous studies, we adopt a multi-factor EEE assessment. We also examine additional influences like the human capital of a nation and its knowledge management system to develop a comprehensive understanding of the macro-level drivers of EEE.

Abstract
Purpose
Little is established about the mechanism through which employee voice is connected to employee mental health. Drawing from social exchange theory, this study examines how employee engagement practices are associated with employee voice, which further influences employee mental health. In addition, the study includes parallel mediation and examines whether perceived interpersonal justice (PIJ) and empathetic leadership (EL) mediate the relationship between employee engagement practices and employee voice.
Design/methodology/approach
Three time-lagged surveys of 457 employees in the Indian information technology (IT) sector were accomplished.
Findings
As hypothesised, employee engagement practices have a positive influence on employee voice. Secondly, employee voice has a positive influence on the employee’s mental health. PIJ and EL were also found to be significant parallel mediators for the relationship among employee engagement practices and employee voice.
Practical implications
This study displays the positive influence of employee engagement practices on employee voice. Further, the employee’s voice influences the employee’s mental health. Therefore, it suggests means for improving its pervasiveness in an organisation.
Originality/value
This research paper is an important contribution as it is one of the few studies examining the role of PIJ and EL as parallel mediators of employee engagement practices and employee voice. It also answers repeated calls for more research on employee mental health in the IT sector.
