Characteristics of built food environments associated with alternative protein food choices: a systematic review.

BACKGROUND: This systematic review contributes to the understanding of the characteristics of built food environments that may be associated with choices of alternative protein foods (APF). Using the built food environment typology proposed by Downs et al., we investigated various environmental structures (e.g., supermarkets, other retailers, farmers' markets, restaurants, schools, and online vendors) and the characteristics that may facilitate or hinder consumers' choices. For example, facilitators and barriers may refer to the physical characteristics of environmental structures, food presentation practices, the organizational strategies or policies operating in the setting, or the actions that retailers or consumers engage in while selling, serving, choosing, trying, or purchasing APF in these environmental structures. METHODS: A systematic review (PROSPERO database preregistration; no. CRD42023388700) was conducted by searching 13 databases for peer-reviewed journals focusing on the fields of economics and business, agriculture, medical sciences, and social sciences. Data searches, coding, and quality evaluations were conducted by at least 2 researchers. A total of 31 papers (36 original studies) were included. The risk of bias was evaluated with the Joanna Briggs Institute quality evaluation tool, with 24 publications presenting low risk of bias. RESULTS: The findings indicate that perceived and actual availability facilitate consumers' APF choices across a built food environment. Several barriers/facilitators were associated with APF choices in specific types of built food environments: the way food is presented in produce sections (supermarkets), consumer habits in terms of green and specialty shopping (grocery stores), and mismatches among retailer actions in regard to making APF available in one type of food environment structure (e-commerce) and consumers' preferences for APF being available in other food environment structures (supermarkets, grocery stores). The effect of a barrier/facilitator may depend on the APF type; for example, social norms regarding masculinity were a barrier affecting plant-based APF choices in restaurants, but these norms were not a barrier affecting the choice of insect-based APF in restaurants. CONCLUSIONS: Addressing barriers/facilitators identified in this review will help in developing environment-matching interventions that aim to make alternative proteins mainstream.

Harmonisation of Pharmaceutical Take-Back Systems in the EU.

When medicines enter the environment, they harm living species and ecosystems. Improper disposal of household pharmaceutical waste increases the concentration of pharmaceuticals in the environment and thus their detrimental impacts. Since 2004, the EU has obliged its Member States to establish 'an appropriate collection system' for unused and/or expired medication. However, as no implementation guidelines exist, large differences in the systems and their use remain. Pressure for adoption of guidelines harmonising the systems across the EU has been increasing. We address the question whether such harmonisation could mitigate pharmaceutical pollution, and which regulatory measures would be appropriate. To answer this, we conduct a comparative investigation of the systems' regulation and an empirical study of citizens' beliefs and behaviour across four European countries. We find a potential for increasing the effectiveness of pharmaceutical take-back systems through their harmonisation and conclude that the EU has the competence and tools to regulate this.

Effectiveness of environmental health and loss framing on household pharmaceutical take-back schemes.

Pharmaceutical pollution poses an emerging environmental and public health problem. Together with increasing medicine use and pharmaceutical manufacturing effluents, improper disposal of household pharmaceutical waste significantly adds to this issue, despite pharmaceutical take-back schemes having been established in many countries. Even where take-back schemes are available return rates remain low. Previous studies have used only survey and interview methodologies and therefore merely described the situation. This study goes further, exploring not only the effects of the availability of information on pharmaceutical take-back schemes but also the effects of the framing of information provided to individuals on their intentions and reported behaviours to collect unused and/or expired household pharmaceuticals and return them to a pharmacy. The data were collected throughout three preregistered, randomised experiments with representative samples (N = 3754). The results show that tapping into individuals' pre-existing conception of the problem and psychological biases through the delivery of environmental health, loss framing information highly increased the odds of returning household pharmaceutical waste. This result is long-lasting (Studies 2 and 3), is found in various European countries (Study 1), and remains robust in all studies. Based on the results, we suggest that, in the context of household pharmaceutical waste management, psychologically informed, proactive approaches combined with targeted local action and services can reduce the psychological and practical barriers to pro-health and pro-environmental behaviour. The findings are used to support a policy recommendation that is cost-efficient, easy to use, and effective.

Public sensemaking of active packaging technologies: A feature-based perspective.

Taking a point of departure in the idea that technology features can act as cues for sensemaking, we explore how the public makes sense of new active packaging technologies; technologies that absorb or release substances from or into the packaging atmosphere, preserving the freshness and safety of food products. Based on data from ten focus groups across five countries (Ireland, Denmark, Italy, Spain and China), we show that sensemaking occurs at two feature-proximity levels. At the first level, we observe the production of proximal representations, where salient technology features drive the sensemaking process and how the individuals come to understand the essence of the technology. At the second level, we observe the production of distal representations, where distinct technology features become less salient, and the holistic understanding of the technology takes over in how individuals come to understand the locus of the technology in broader contexts. Our insights contribute to theory regarding public sensemaking of novel technologies and have practical implications for stakeholders who aim to increase their adoption prospects.

Social discourses of healthy eating. A market segmentation approach.

This paper proposes a framework of discourses regarding consumers' healthy eating as a useful conceptual scheme for market segmentation purposes. The objectives are: (a) to identify the appropriate number of health-related segments based on the underlying discursive subject positions of the framework, (b) to validate and further describe the segments based on their socio-demographic characteristics and attitudes towards healthy eating, and (c) to explore differences across segments in types of associations with food and health, as well as perceptions of food healthfulness.316 Danish consumers participated in a survey that included measures of the underlying subject positions of the proposed framework, followed by a word association task that aimed to explore types of associations with food and health, and perceptions of food healthfulness. A latent class clustering approach revealed three consumer segments: the Common, the Idealists and the Pragmatists. Based on the addressed objectives, differences across the segments are described and implications of findings are discussed.

Traceability information carriers. The technology backgrounds and consumers' perceptions of the technological solutions.

The implementation of traceability in the food supply chain has reinforced adoption of technologies with the ability to track forward and trace back product-related information. Based on the premise that these technologies can be used as a means to provide product-related information to consumers, this paper explores the perceived benefits and drawbacks of such technologies. The aim is to identify factors that influence consumers' perceptions of such technologies, and furthermore to advise the agri-food business on issues that they should consider prior to the implementation of such technologies in their production lines. For the purposes of the study, a focus group study was conducted across 12 European countries, while a set of four different technologies used as a means to provide traceability information to consumers was the focal point of the discussions in each focus group. Results show that the amount of and confidence in the information provided, perceived levels of convenience, impact on product quality and safety, impact on consumers' health and the environment, and potential consequences on ethical and privacy liberties constitute important factors influencing consumers' perceptions of technologies that provide traceability.

Human decision-making biases in the moral dilemmas of autonomous vehicles.

The development of artificial intelligence has led researchers to study the ethical principles that should guide machine behavior. The challenge in building machine morality based on people's moral decisions, however, is accounting for the biases in human moral decision-making. In seven studies, this paper investigates how people's personal perspectives and decision-making modes affect their decisions in the moral dilemmas faced by autonomous vehicles. Moreover, it determines the variations in people's moral decisions that can be attributed to the situational factors of the dilemmas. The reported studies demonstrate that people's moral decisions, regardless of the presented dilemma, are biased by their decision-making mode and personal perspective. Under intuitive moral decisions, participants shift more towards a deontological doctrine by sacrificing the passenger instead of the pedestrian. In addition, once the personal perspective is made salient participants preserve the lives of that perspective, i.e. the passenger shifts towards sacrificing the pedestrian, and vice versa. These biases in people's moral decisions underline the social challenge in the design of a universal moral code for autonomous vehicles. We discuss the implications of our findings and provide directions for future research.
