Polytopal realizations of finite type $\mathbf{g}$-vector fans

, 2018
This paper shows the polytopality of any finite type $\mathbf{g}$-vector fan, acyclic or not. In fact, for any finite Dynkin type $\Gamma$, we construct a universal associahedron $\mathsf{Asso}_{\mathrm{un}}(\Gamma)$ with the property that any $\mathbf{g}

From Task Motivation to L2 Learning: Understanding Links through Learners' Task Engagement

TESOL Quarterly, EarlyView.
Abstract This study investigated whether learners' task motivation predicts their task engagement, and whether their task engagement is associated with subsequent L2 learning. Task motivation was operationalized through situated expectancy‐value theory (SEVT; Eccles & Wigfield, 2020), a model of the proximal (i.e., task‐specific) social‐cognitive ...

Iowa Population Exposures to Metals and Metalloids in Well Water

Environmental Toxicology, EarlyView.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

Between‐country differences in the psychosocial profiles of British cattle farmers

Veterinary Record, EarlyView.
Abstract Background Psychosocial factors are important for the uptake of livestock disease control measures by farmers and can differ by region, which would have implications for disease control nationally. Methods We investigated altruism, trust, psychological proximity and the COM‐B behaviour change framework in a survey of 475 British cattle farmers
