A Match Made in Heaven? Do Religious and General Appeals Instill Hope for Reduction of Food Waste
(SAGE Publications on behalf of the Australian and New Zealand Marketing Academy., 2025-10-03) Khalil M; Lang B; Septianto F; Northey G
Globally, approximately 30% of food is wasted, leading to severe social, environmental, and financial consequences. Household interventions are crucial, given that most waste occurs at this level. Despite various message trials for waste reduction, the impact of incorporating religious appeals into general messages and their relation to hope remains underexplored due to the complexities of the food waste context. This research fills this void by conducting four experiments to investigate the impact of religious (vs. general) and communal (vs. agentic) appeals on consumers’ intention to reduce food waste. Participants were randomly exposed to various appeals to assess how the appeals should be matched to increase intention to reduce food waste. Results show that religious appeals are less effective than general appeals in increasing behavioral intention, and that in order for food waste to be reduced, general appeals should be paired with communal (vs. agentic) appeals. The study also shows that state hope is the underlying mechanism of this effect. This research contributes to the literature on religious appeals, communal (vs. agentic) appeals, and hope theory.
A systematic review and future agenda on continuance intentions in mobile apps
(Elsevier Ltd, 2025-12-01) Veronika S; Lee MSW; Lang B; Putra P
Technology changes at ever increasing speeds. Therefore, it is crucial for practitioners and academics to understand why users’ intend to continue or discontinue their usage. This paper presents a current and comprehensive systematic literature review on continuance intentions for mobile applications. The review analyzes 119 studies from the Scopus database (January 2019–December 2023) using the PRISMA, SPAR, and TCCM frameworks. It identifies key theoretical models, determinants of mobile app continuance intention, research methods, existing gaps, and future research directions. Findings reveal that several well-recognised theoretical models are frequently applied in the literature on continuance intention. Consequently, the variables derived from these models are among the most commonly measured by researchers. Additionally, the majority of studies in this area employ quantitative methods, with structural equation modelling being most widely used. This review categorises the literature based on mobile application classifications and six distinct sets of factors influencing continuance intention: psychological, technical, social, behavioural, contextual, and barriers. Furthermore, it explores the outcomes associated with continuance intention. The paper identifies two primary areas for future research: the development of a conceptual framework and research design. It also highlights research opportunities related to emerging technologies and the gap between intentions and actual behaviours.
Exploring diverse food system actor perspectives on gene editing: a systematic review of socio-cultural factors influencing acceptability
(Springer Nature B V, 2024-06) Henderson K; Lang B; Kemper J; Conroy D
Despite the promise of new gene editing technologies (GETs) (e.g., CRISPR) in accelerating sustainable agri-food production, the social acceptability of these technologies remains unclear. Prior literature has primarily addressed the regulatory and economic issues impacting GETs ongoing acceptability, while little work has examined socio-cultural impacts despite evolving food policies and product commercialisation demanding input from various actors in the food system. Our systematic review across four databases addresses this gap by synthesising recent research on food system actors’ perspectives to identify the key socio-cultural factors influencing GET acceptability. This review extends prior literature by including views from a more diverse range of actors (e.g., farmers and NGOs) and provides a better understanding of their perceived social benefits and concerns. We find food system actors perceive positive and negative impacts of using GETs in agriculture. These perspectives are often entangled in broader debates regarding sustainability and food systems issues (e.g., social justice). We discuss practical recommendations for policymakers, agri-food industry managers, and scientists to better align gene edited foods (GEFs) with food system actors’ values. GEF policy, development, and commercialisation must reflect social values such as collective wellbeing and transparency to improve actors’ acceptability. More research is required among marginalised food actors such as Indigenous and smallholder farmers.

'It's somewhere here, isn't it'? The provision of information and health warnings for alcoholic beverages sold online in New Zealand and the United Kingdom
(John Wiley and Sons Australia, Ltd on behalf of Australasian Professional Society on Alcohol and other Drugs, 2023-02-10) Shen V; Haffner L; Walker N; Ni Mhurchu C; Lang B
INTRODUCTION: Alcohol beverages in many countries are required to display health information and warnings on all product packaging, given the individual and societal harm caused by alcohol. It is unclear whether consumers purchasing alcohol online are able to easily view such information. This study examines the presence, type and location of mandatory and voluntary health information and warnings consumers are exposed to when entering online alcohol retail shopping environments in the United Kingdom (UK) and New Zealand (NZ). METHODS: Using an observational study design, 1407 randomly sampled alcoholic beverages from 14 online alcohol retailers (7 per country) were reviewed to ascertain the visual presence or absence of mandatory and voluntary health information and warnings. RESULTS: UK online alcohol retailers were more compliant than NZ retailers in showing mandatory health information (e.g., alcohol by volume percentage was visible on 92% of alcoholic beverages sold online in the UK, compared to 31% in NZ, p < 0.001). A similar pattern was noted for voluntary health warnings. Online retailers in both countries had a low proportion of alcohol products with the viewable mandatory information, and voluntary health warnings were rarely present and/or viewable. DISCUSSION AND CONCLUSIONS: Mandatory health information and warnings for alcoholic beverages are not fully adhered to within the UK and NZ online retail environments, impacting the ability of consumers to make informed purchase decisions. In both countries, alcohol policy needs to stipulate that mandatory health information and warnings should be clearly viewable on the product page and product imagery of online alcohol retailers.
Perception is reality: qualitative insights into how consumers perceive alcohol warning labels
(Oxford University Press on behalf of the Medical Council on Alcohol, 2024-09) Kemper J; Rolleston A; Matthews K; Garner K; Lang B; Jiang Y; Ni Mhurchu C; Walker N
AIMS: This study explores perspectives of on-pack alcohol warning labels, and how they might influence alcohol purchase and/or consumption behavior to inform culturally appropriate label design for effective behavior change. METHODS: New Zealand participants ≥18 years, who reported having purchased and consumed alcoholic beverages in the last month were recruited via a market research panel and grouped into 10 focus groups (n = 53) by ethnicity (general population, Māori, and Pacific peoples), age group, and level of alcohol consumption. Participants were shown six potential alcohol health warning labels, with design informed by relevant literature, label framework, and stakeholder feedback. Interviews were transcribed and analyzed via qualitative (directed) content analysis. RESULTS: Effective alcohol labels should be prominent, featuring large red and/or black text with a red border, combining text with visuals, and words like "WARNING" in capitals. Labels should contrast with bottle color, be easily understood, and avoid excessive text and confusing imagery. Participants preferred specific health outcomes, such as heart disease and cancer, increasing message urgency and relevance. Anticipated behavior change included reduced drinking and increased awareness of harms, but some may attempt to mitigate warnings by covering or removing labels. Contextual factors, including consistent design and targeted labels for different beverages and populations, are crucial. There was a strong emphasis on collective health impacts, particularly among Māori and Pacific participants. CONCLUSIONS: Our findings indicate that implementing alcohol warning labels, combined with comprehensive strategies like retail and social marketing campaigns, could effectively inform and influence the behavior of New Zealand's varied drinkers.
Threat or opportunity? A stakeholder perspective on country of origin brand and promoting gene edited foods
(Taylor and Francis Group, 2025-06-16) Henderson K; Kemper J; Lang B; Conroy D; Frethey-Bentham C
Gene editing technologies could address critical challenges in the food system by producing gene edited foods (GEFs) with enhanced nutrition and climate resilient traits. Despite this potential, support for novel GEFs from stakeholders involved in their development, commercialisation, and marketing, remains uncertain. This research investigates the role of country of origin (COO) branding in promoting GEFs as sustainable food products. Through 28 interviews with New Zealand (NZ) agri-food industry stakeholders, we identify three key themes, 1) Perceptions of GEFs and NZ’s COO brand, 2) Inconsistency and incoherency in COO, and 3) Co-creating an adapted and repositioned COO. Findings reveal that stakeholders viewed the misalignment of New Zealand’s COO brand, often associated with ‘natural’ and ‘sustainable’, as a threat (brand damage) or as an opportunity (brand repositioning). This study provides new insights into branding dynamics by uncovering responses to incoherences created by GEFs within a well-established COO brand. It also offers valuable insights for stakeholders and marketing practitioners on the use of COO branding for sustainable foods.
Vaping cessation strategies and triggers for relapse amongst people from New Zealand who have vaped
(John Wiley and Sons Australia, Ltd on behalf of Australasian Professional Society on Alcohol and other Drugs, 2025-06-11) Rahimi M; Lang B; Shahab L; Brown J; Palmer A; Kemper J; Bullen C; Laking G; Nosa V; Parag V; Walker N
Introduction: In New Zealand (NZ) vapes (e-cigarettes) are a government-endorsed strategy to help people stop smoking, as well as being used recreationally by people who have never smoked. Nicotine vapes are addictive and many users want to quit. We surveyed current and past users of nicotine vapes to gather insights about their vaping cessation reasons and strategies. Methods: In December 2022, we undertook a web-based survey in NZ using market research survey panels. Eligible panellists were aged ≥16 years, did not currently smoke and had vaped nicotine. Questions focused on demographics, smoking and vaping status, vaping dependence, strategies used to quit vaping, and triggers for vaping relapse. Results: One thousand one hundred nineteen participants completed the survey: 144 had never smoked; 975 used to smoke, 401 currently vaped nicotine, and 718 used to vape nicotine. Participants were predominantly aged ≥25 years (89%); 63% were female, and 21% were Indigenous Māori and/or Pacific. Predictors of vaping dependence were having smoked or vaped for ≥2 years and vaping >3% nicotine. Reasons for trying to quit vaping included health concerns, disliking feeling dependent, and cost. Quitting strategies included stopping abruptly, nicotine tapering and family/friend support. Triggers for relapse were stress, being around others who vaped and nicotine withdrawal. Discussion and Conclusion: In NZ reasons to quit and triggers to return to vaping are similar to quitting smoking. Until more research is available, it seems appropriate to support people who wish to stop vaping with similar strategies used to support people to quit smoking.
