Local food has received considerable attention in recent years. It is seen as a response to increased demand for authentic foods, just as organic foods have been considered to be. It is unclear whether organic and local are two complementary or competitive trends in food consumption. This study addresses this question with a mixed methods investigation of why Danish consumers of organic products and conventional consumers of local products choose locally produced food, what values and opinions they associate with local food, and whether there are sociodemographic differences between the groups. The results show that the same values and opinions tended to motivate organic consumers and a group of committed conventional consumers of local foods. However, organic consumers were much more likely to include environmental issues in their deliberations. Another group of local-food consumers did not seem to be motivated by values and opinions when purchasing locally produced foods. Some sociodemographic differences between the groups were found: organic consumers were more likely to live in the capital than committed local consumers; to have a lengthy education than consumers of local foods; and committed local-food consumers were more likely than organic consumers to have a vocational education. The article concludes that while it is to some extent the same preference for authentic food that motivates organic and committed conventional local-food consumers to buy locally produced foods, it is at the same time different types of consumers who prefer (conventional) local food and organic food.

The abnormal expression of acetylcholinesterase (AChE) is linked to the development of various diseases. Accurate determination of AChE activity as well as screening AChE inhibitors (AChEIs) holds paramount importance for early diagnosis and treatment of AChE-related diseases. Herein, a fluorescent and colorimetric dual-channel probe based on gold nanoclusters (AuNCs) and manganese dioxide nanosheets (MnO NSs) was developed.

The urban agglomeration represents the predominant form of new urbanisation, yet the evolution of its internal spatial structure exhibits pronounced spatial and temporal heterogeneity. This study concentrates on the Bohai Rim urban agglomeration, one of three major urban agglomerations in China, which has received comparatively limited research attention but has also undergone substantial urbanisation. Therefore, we reassessed and explored the spatial-temporal evolution of the spatial structure of urban expansion using Exploratory Spatiotemporal Data Analysis (ESTDA), and summarized the driving mechanisms using Geographically and Temporally Weighted Regression (GTWR).

The cytokine homologs, particularly transforming growth factor (TGF)-β, is a crucial immunomodulatory molecule and involved in growth and developmental processes in several helminths. In this study, the basic properties and functions of T. spiralis TGF-β homolog 2 (TsTGH2) were characterized using bioinformatics and molecular biology approaches.

By employing the stabilizer in the supersonic gas nozzle to produce the plasma density profile with a sharp downramp, we have experimentally demonstrated highly stable electron beam acceleration based on the shock injection mechanism in laser wakefield acceleration with the use of a compact Ti:sapphire laser. A quasi-monoenergetic electron beam with a peak energy of 315 MeV ± 12.5 MeV per shot is generated.

Background: In May 2020, Oakland became the most populous city in California to implement a minimum floor price law (MFPL), requiring tobacco retailers to sell cigarettes and cigars at $8 or more per pack/package. Policy enforcement began in August 2020.
Methods: We estimated changes in cigarette and cigar prices and unit sales for Oakland versus a matched comparator during the first 20 months following MFPL implementation using a synthetic difference-in-differences approach.
