Business Strategy and the Environment, EarlyView.ABSTRACT Rice production sustains food security and rural livelihoods across many low‐income countries but remains highly vulnerable to climate‐related hazards, including floods, droughts, salinity intrusion and heat stress, which reduce yields and threaten the long‐term sustainability of rice production.

Les sens procéduraux intersubjectifs de la particule UP
Corela, 2006 In this paper I adopt the tenets of historical pragmatics and make use of previous scholarly work on the adverbial particle up to present hypotheses on the existence in PDE and historical development of two intersubjective procedural meanings of the ...

Lasso for hierarchical polynomial models
Canadian Journal of Statistics, EarlyView.Abstract The divisibility conditions implicit in a polynomial hierarchy suggest parameter constraints in regression. With this idea, we establish strong and weak hierarchies for both the lasso and relaxed lasso. Our proposal extends prior work on hierarchical lasso, which was mainly concerned with models of degree 2.

Reflex seizures and epilepsy surgery: A network approach case‐based exploration
Epileptic Disorders, EarlyView.Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.

Phase Transitions Related to the Pigeonhole Principle [PDF]
, 2014 Since Jeff Paris introduced them in the late seventies [Par78], densities turned out to be useful for studying independence results. Motivated by their simplicity and surprising strength we investigate the combinatorial complexity of two such densities which are strongly related to the pigeonhole principle.

The Strong Nash‐Williams Orientation Theorem for Rayless Graphs
Journal of Graph Theory, EarlyView.ABSTRACT In 1960, Nash‐Williams proved his strong orientation theorem that every finite graph has an orientation in which the number of arc‐disjoint directed paths between any two vertices is at least half the number of undirected edge‐disjoint paths between them (rounded down).

Most primitive groups are full automorphism groups of edge-transitive hypergraphs [PDF]
, 2014 We prove that, for a primitive permutation group G acting on a set X of size n, other than the alternating group, the probability that Aut (X,YG) = G for a random subset Y of X, tends to 1 as n → ∞.

Journal of Graph Theory, EarlyView.ABSTRACT A 2‐edge‐coloured graph G $G$ is called locally complete if for each vertex v $v$, the vertices adjacent to v $v$ through edges of the same colour induce a complete subgraph in G $G$. Locally complete 2‐edge‐coloured graphs have nice properties, and there exists a polynomial algorithm to decide whether such a graph has an alternating ...

Journal of Graph Theory, EarlyView.ABSTRACT Lovász et al. proved that every six‐edge‐connected graph has a nowhere‐zero three‐flow. In fact, they proved a more technical statement, which says that there exists a nowhere‐zero three‐flow that extends the flow prescribed on the incident edges of a single vertex z $z$ with bounded degree. We extend this theorem of Lovász et al.
