Abstract Consumption advice to ensure the health and safety of fish consumers remains urgent to handle the ever-increasing panic over heavy metal toxicity. Moreover, studies of fish consumption rarely focus on the perceptions and awareness of consumers. Considering this, the present study examines the knowledge and perceptions of the risks and benefits of fish consumption among consumers of Laguna de Bay to explore their willingness to follow fish consumption advice. The seasonal variation in selected types of heavy metal contamination in two commercially important fish species, tilapia and mudfish, was analysed and a vulnerability map based on the risk‒benefit ratio was produced for Laguna de Bay. Furthermore, this study formulates fish consumption advice for consumers of fish in the area. Primary data on consumers’ perceptions were collected through a questionnaire, whereas heavy metal contamination data were compiled from the best available literature. We concluded that people’s willingness to adopt consumption advice is mostly dependent on their existing level of fish consumption. Moreover, consumption advice is formulated to indicate restrictions on consumption for the areas identified as vulnerable due to contamination. This empirical study can serve as a model for the future development of fish consumption advice in the region.

Definitions for the culturally trendy “clean” eating phenomenon vary: whereas some characterize it as natural and healthy, others adopt more restrictive, moralizing, and affectively-laden definitions that may reflect disordered eating. We examined levels of familiarity with “clean” eating, sources of information, and perceptions of this dietary trend among a large, diverse sample of U.S. adolescents and emerging adults recruited from the National MyVoice Text Message Cohort (N = 1266; ages 14-24 years). Participants answered five questions assessing knowledge of “clean” eating, definitions, perceived healthiness vs. harm, and willingness to adopt “clean” eating, and responses were coded by three trained researchers. Results indicate that 55% of respondents had previously heard of “clean” eating, most commonly through social media, other online sources, and peers. Definitions were heterogeneous, with 40% offering “non-processed” or “whole foods” and 13% noting “non-GMO” or “organic” components. Few respondents (0.6%) expressed outright skepticism about “clean” eating, but many (30%) identified dietary avoidance and restriction as part of the definition. Overall, 71% characterized “clean” eating as a healthy approach, whereas 6% flagged it as “unhealthy” and 18% noted elements of both healthfulness and harm; 41% reported they “probably would” try “clean” eating themselves. Present findings highlight high levels of awareness and positive attitudes toward “clean” eating among young people in the U.S., with little recognition of the potential risks of dietary restriction. Further research could clarify potential risks of “clean” eating and related dietary trends and thus inform strategies for eating disorder prevention.

Quinoa is considered a strategic crop because it is well adapted to the adverse abiotic conditions of the Bolivian Altiplano; however, the average yield is low. Previous studies have demonstrated that quinoa yield would increase with deficit irrigation technology. Nevertheless, to irrigate quinoa is not a normal practice in the farming systems of the Altiplano. This paper examines the main factors that determine the attitude of farmers towards adopting deficit irrigation using a sample of 137 surveys in seven communities of the Central Altiplano. Statistic analysis demonstrates that the most important factors influencing farmers' willingness for irrigation adoption are the acreage planted with quinoa, quantity of surplus production for trading, and having irrigation experience. Also, the age and education level were important to know willingness to adopt a new technology. Therefore, deficit irrigation is more likely to be performed in area where farmers own larger fields and where there is already certain type of irrigation.

Abstract Background Sustainability of energy is key for quality life; thus, the use of clean energy at the household level warrants moving from fossil-based energy to modern forms like biogas. However, the joint interactive effect of household income, biogas usage and willingness to adopt a single-stage solar-supported hyper-thermophilic anaerobic biogas digester (SSHTABD) is not known. Methods A cross-sectional survey was carried out to assess the willingness of residents of Elmina to adopt the SSHTABD. Stratified and simple random sampling techniques were used to select 219 respondents fitted into a complementary log–log regression model. Results Household willingness to adopt the SSHTABD was 86%. Among them are households not willing to use biogas but have high income and households willing to use biogas but have either low or high income are more likely to adopt the technology compared to households not willing to use biogas and have low income. Households not willing to use biogas, but have high income (OR = 1.725, confidence interval [CI] 0.803–3.706) and households willing to use biogas, but have low income (OR = 1.877, CI 1.103–3.188) compared to households willing to use biogas and have high income (OR = 1.725, CI 1.080–3.451) are more likely to adopt the technology as households not willing to use biogas and have low income. Additionally, households employed under the formal government sector, formal and informal private sectors are 40%, 136% and 103%, respectively, more likely to adopt the technology than those unemployed. Conclusion The high willingness of households to adopt the technology calls for government to support households to own biogas digesters thus requires policy interventions and interdisciplinary research.

Abstract Background The COVID-19 crisis has meant a significant change in the lifestyle of millions of people worldwide. With a lockdown that lasted almost three months and an impulse to new normality, transport demand has suffered a considerable impact in the Spanish case. It is mandatory to explore the effect of the pandemic on changes in travel behaviour in post-COVID-19 times. Methodology A nationwide survey was carried out during the lockdown in Spring 2020 to overview the recent changes. The survey collected both stated preferences (socio-demographic characteristics and mobility-related attributes), and revealed preferences (individuals’ habits, especially in the frequency of the trips according to the trip purpose, and opinions regarding the willingness and acceptability of these changes, and which actors would have to drive them, and how) of individuals. This paper aims to study and understand the willingness to adopt a set of measures to improve the safety conditions of public transport and shared mobility services against possible contagion from COVID-19 and the willingness to pay for them. Results The results obtained show that some measures, such as the increase of supply and vehicle disinfection, result in a greater willingness to use public transport in post-COVID-19 times. Similarly, the provision of covers for handlebars and steering wheels also significantly increases individuals’ willingness to use sharing services. However, respondents expect that these measures and improvements would be implemented but maintaining the same pre-COVID-19 prices. The results of this research might help operators deploy strategies to adopt their services and retain users.

When confronted with a new product, consumers often find it difficult to predict how it will perform, and such uncertainty reduces consumers’ willingness to adopt the product. In this paper, we consider a market whereby consumers decide when and which product to buy, given that they know the product quality of the incumbent but are uncertain about that of the entrant. We investigate how consumer uncertainty about product quality affects firms’ behavior-based pricing and customer acquisition and retention dynamics. Using a two-period vertical model, we find that, under high-end encroachment, an increase in consumer uncertainty reduces the entrant’s profit and hurts the incumbent’s profit when the quality differential between the products is relatively small, whereas, under low-end encroachment, increasing uncertainty not only benefits the incumbent but also can favor the entrant. An important implication for entrants is that the marketing activities, which aim to reduce consumer uncertainty about product functionalities, may fail to improve profitability. We also find that the entrant lowers the price for uninformed customers and raises the price for repeat buyers under high-end encroachment but lowers the price for all customers under low-end encroachment. We further examine the subsidy strategy and show that, when the entrant’s product has a significant quality advantage and consumer uncertainty is high but not very high, the optimal strategy for the entrant is to acquire all consumers who do not buy from the incumbent by providing subsidies and to drop the low-valuation customers by means of a high price after their uncertainty is resolved.
