Flexible methods for species distribution modeling with small samples
Species distribution models (SDMs) predict where species live or could potentially live and are a key resource for ecological research and conservation decision‐making. However, current SDM methods often perform poorly for rare or inadequately sampled species, which include most species on earth, as well as most of those of the greatest conservation ...

Consumers' valuation for cultured meat: A multi‐city choice experiment in China
Abstract Despite the rising interest in cultured meat, there remains scant information on whether consumers would value it. This study evaluated consumers' willingness‐to‐pay (WTP) for cultured chicken and examined how information affects WTP. Using a choice experiment with a total of 571 samples, the results found that consumers are unwilling to pay a

Application of the fractional factorial design in multiple W/O/W emulsions
In presented research, multiple W/O/W emulsions were developed by using experimental design method. A 24-1 fractional factorial design was performed by varying the following input parameters: primary polymeric emulsifier (PEG 30-dipolyhydroxystearate ...
