Abstract
Purpose
Food waste has strong ecological, economical and social implications. Focusing on waste perceptions and behavior according to food types, this paper aims to propose that vice or virtue food categories determine cognitive and behavioral reactions to food waste. The authors examine the psychological mechanism underlying the differential waste perceptions and behavior.
Design/methodology/approach
The authors conduct five studies, including a field study, to provide converging evidence that supports this theorization.
Findings
This study demonstrates that consumers feel that trashing vice food is more wasteful than trashing virtue food. They are less willing to waste vice food and more comfortable with wasting virtue food. Consequently, they waste more virtue than vice foods. The authors demonstrate that counterfactual thinking explains the food type effect on waste.
Research limitations/implications
This paper provides a conceptual framework for understanding and explaining food waste perceptions and behavior across vice and virtue food categories. This paper identifies counterfactual thinking as underpinning the psychology of waste perceptions and behaviors. The findings extend the growing research on subconscious and unintentional food waste, the food consumption literature and the psychology of waste literature.
Practical implications
The differential waste perceptions and behavior provide several implications for waste interventions and consumer education. By expanding theories of consumer food waste, this paper provides material for educational campaigns aimed at reducing waste and improving healthful eating.
Social implications
Consumers can benefit from understanding their tendency to avoid wasting vice foods but will waste virtue foods with little compunction. Waste aversion may be a reason people consume vice foods beyond satiation. Consumers may overconsume vice foods because they are so acutely averse to wasting them, with detrimental consequences for health and welfare.
Originality/value
To reduce consumer food waste, one must gain deeper insights into factors shaping consumer food waste perceptions and behavior. Food waste studies have been increasing but have overlooked the power of consumer perceptions in driving food waste consequences. To the best of the authors’ knowledge, no prior study has examined how food type affects waste perceptions and behavior. This research fills this gap.

Abstract
Purpose
The purpose of this paper is to examine the relationship between self-enhancement and helping behavior/intentions. Some people are more inclined than others to engage in helping behaviors. Determining what individual characteristics are related to helping behavior could have important implications for both marketers and non-profit organizations. Drawing on research on self-enhancement, this paper examines the relationship between the “above-average effect” (the tendency of individuals to rate themselves more favorably than they rate others) specifically on altruistic traits and helping behavior.
Design/methodology/approach
Data were collected through two surveys and analyzed with correlation analysis, path analysis and structural equation models.
Findings
In two studies, we find a positive relationship between interdependence and self-enhancement and a positive relationship between self-enhancement and helping behavior (volunteering in Study 1 and donation behavior in Study 2). We further show that self-enhancement mediates the effect of interdependence on helping. Personal importance of altruistic traits is shown to underlie these relationships.
Practical implications
By understanding the antecedents of helping behaviors, non-profit and charity organizations, social marketers and other advocates of pro-social behaviors can enhance the effectiveness of their appeals. Our findings provide insights for both messaging and targeting.
Originality/value
This study examines the relationship between self-enhancement and helping behavior. In so doing, it contributes to the self-enhancement literature by identifying the relationship between self-construal and self-enhancement. It also extends understanding of the relationship between these two constructs and helping behavior by revealing the mediating role of self-enhancement on helping behavior.

Abstract
Purpose
The purpose of this paper is to expand knowledge of supply chain management (SCM) by empirically testing the moderating effects of supply chain dynamism (SCD) on the association between supply chain integration (SCI) and logistics performance.
Design/methodology/approach
Survey methods were used to measure the perspective of South Korean manufacturers. Moderated hierarchical regression analysis was undertaken to test the proposed hypotheses empirically.
Findings
The findings suggest that SCI can enhance logistics performance when the level of SCD is high, but the effects of SCI on logistics performance are blurred at low levels of SCD.
Originality/value
This finding provides empirical evidence of the moderating effects of SCD on the SCI-logistics performance link and offers a new interpretation of the relationship. This work contributes to SCM disciplines by providing theory-driven and empirically tested explanations.

Abstract
Purpose
With the emergence of social media, online influencers have played a major role in brand marketing. This study aims to examine how Malaysian young adults perceive advertising endorsements of celebrities and online influencers within the framework of parasocial relations and multiculturalism.
Design/methodology/approach
This study engaged 42 Malaysian young adults aged 18–24 in semistructured interviews. They were asked to share a television commercial with celebrity endorsement and explain why it was impressive. They were then asked explicitly to compare traditional celebrities and online influencers in terms of attractiveness, credibility and endorsement effects.
Findings
Advertising execution strategies and emotional attachment to advertising endorsers are the two main reasons for making an advertisement impressive. Interviewees demonstrate strong emotional attachments to celebrities who are national icons. Online influencers are perceived as more relatable, authentic and credible than traditional celebrities. Interviewees perceive that endorsements by traditional celebrities were more effective for luxurious brands and brands targeting older consumers. On the other hand, endorsements by online influencers were perceived to be more effective for low-involvement product categories and brands that target younger consumers.
Research limitations/implications
This study presents a summary of the parallel perceptions of online influencers and celebrities to explain how young consumers evaluate advertising with celebrity and social media influencer endorsement.
Practical implications
Malaysian young adults perceive endorsers as people who guide their experiences with ads. Adopting an endorser who is young, has a trendy image, and has a similar cultural background enhances the relatability of ads for young adults. National sports heroes can serve as nation-building agents through celebrity endorsement in advertising.
Originality/value
Few studies directly compare the endorsement effects of celebrities and online influencers in a multicultural setting. This study provides marketing and theoretical insights to unravel the influencing mechanism of parasocial relations and multiculturalism.

Abstract
Purpose
This paper aims to investigate the reusability of metal/metal oxide-coupled ZnO nanorods (ZnO NRs) to degrade rhodamine B (RhB).
Design/methodology/approach
ZnO NRs particles were synthesized by precipitation method and used to remove various types of metal ions such as Cu2+, Ag+, Mn2+, Ni2+, Pb2+, Cd2+ and Cr2+ ions under UV illumination. The metal/metal oxide-coupled ZnO NRs were characterized by scanning electron microscope, X-ray diffraction and UV-Vis diffuse reflectance. The photodegradation of RhB dye by these metal/metal oxide-coupled ZnO NRs under UV exposure was assessed.
Findings
The metal/metal oxide-coupled ZnO NRs were successfully reused to remove RhB dye in which more than >90% of RhB dye was degraded under UV exposure. Furthermore, the coupling of Ag, CuO, MnO2, Cd and Ni particles onto the surface of ZnO NRs even enhanced the degradation of dye. The dominant reactive species involved in the degradation of RhB dye were •OH- and •O2−-free radicals.
Research limitations/implications
The coupling of metal/metal oxide onto the surface of ZnO NRs after metal ions removal could affect the photocatalytic performance of ZnO NRs in the degradation of organic pollutants in subsequent stage.
Practical implications
A good reusability performance of metal/metal oxide-coupled ZnO NRs make ZnO NRs become a desirable photocatalyst material for the treatment of wastewater, which consists of both heavy metal ions and organic dyes.
Originality/value
Metal/metal oxide coupling onto the surface of ZnO NRs particles improved subsequent UV-assisted photocatalytic degradation of RhB dye.
