A nationally representative sample (N = 1050) responded to a survey testing possible connections between Americans' attention to media about President Donald J. Trump's preference for fast food, their perceptions of Trump, and public perceptions and behavioral intentions regarding fast food consumption. This survey utilized measures aimed at integrating theory about audience responses to celebrity health issues with the Theory of Planned Behavior and found a significant positive relationship between attention to media about Trump's diet and perceptions that fast food is socially acceptable, as well as intentions to consume it. Some, but not all, media-related variables in the analyses were positively associated with fast food perceptions and intentions, even after controlling for demographic and psychosocial factors. Attention to media specifically about Trump's dietary habits was more often associated with fast food-related perceptions and outcomes than were other types of media attention. Additionally, having a positive parasocial relationship with Trump was positively associated with increased perceived acceptability of fast food. There were also differences in the connections between attention to media about Trump's diet, parasocial relationships with Trump, and fast food perceptions and consumption intentions for audiences with different political affiliations. For instance, attention to media about Trump in general was positively associated with more positive attitudes toward fast food for Republicans, but not for Democrats are those unaffiliated with either political party. Attention to media specifically about Trump's diet was positively related to fast food attitudes for both Republicans and Democrats but not unaffiliated individuals. This study demonstrates the important role of social, political, and media influences in shaping fast food related perceptions and preferences and offers many potential avenues for future research in this area.

detection suffers from slow analysis time and high costs, along with the need for specificity. While state-of-the-art electrochemical biosensors are cost-efficient and easy to implement, their sensitivity and analysis time still require improvement. In this work, we present a paper-based electrochemical biosensor utilizing magnetic core-shell FeO@CdSe/ZnS quantum dots (MQDs) to achieve fast detection, low cost, and high sensitivity.

Triploids are widely used to rapidly achieve genetic improvements of organisms due to their fast growth and enhanced environmental adaptability. Artificially induced triploids are generally considered to be infertile owing to the obvious inhibition of gonadal development. Recently, some fertile individuals with reduced advantages have been found in triploid bivalves, which is a notable deviation from the original intention of artificially inducing triploids.

In this work, a series of three-dimensional (3D) SERS substrate were successfully fabricated by assembling silver nanoparticles (AgNPs) onto a porous gelatin sponge (GS) for highly sensitive thiram residues detection in vegetables. These 3D micro-nanostructures could induce the sufficient surface plasmon resonance (SPR) effect of noble metals on their surface and achieve high enrichment of pollutant molecules. As crystal violet (CV) was used as a probe molecule, the lowest CV solution could be detected at 10 M, and the enhancement factor (EF) was calculated to be 9.

Our current agricultural system faces a perfect storm-climate change, burgeoning population, and unpredictable outbreaks like COVID-19 disrupt food production, particularly for vulnerable populations in developing countries. A paradigm shift in agriculture practices is needed to tackle these issues. One solution is the diversification of crop production.

This study aims to analyze the configuration of inequalities in one of Argentina's most significant production zones for fresh vegetables and cut flowers, located in Greater La Plata, Buenos Aires Province. This ongoing anthropological research, initiated in 2021, employs methods such as participant observation, interviews, food mapping, and digital ethnography. Among the main findings, we highlight that this production zone exhibits, in both its origins and daily operations, certain racist dynamics that are not solely generated by the host society toward migrants but are disseminated throughout the social fabric, including by migrant producers themselves.
