The Issue of Pre‐Islamic Arabic Christian Poetry Revisited

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Is only very little Arabic Christian poetry extant from pre‐Islamic times? While distancing myself from Louis Cheikho's (1859–1927) view that almost all pre‐Islamic poets were Christians, I contend in this article that some of them indeed were.

Market regulation and productivity: The case of the Canadian Wheat Board

American Journal of Agricultural Economics, EarlyView.
Abstract Changes to regulatory environments influence firm‐level incentives, which can move the productivity frontier or reposition firms within an existing frontier. Estimating causal effects of policy changes requires a credible counterfactual for productivity in the absence of policy change.

Review of lightning protection standard in building structures in Nigeria. [PDF]

, 2014
A lightning protection system performs a simple task. It provides a specified path on which lightning can travel. When a building structure is equiped with a lightning protection system, the distructive power of the lightning strike is directed safely ...

Punchline with(out) purpose: Integrating research on instructional humour and seductive details

British Journal of Educational Psychology, EarlyView.
Abstract Introduction We integrated research on instructional humour and seductive details to investigate when affiliative course‐related humour is effective or rather ineffective for learning. We assumed that instructional humour without a cognitive function (irrelevant humour) would have detrimental effects on learning performance resembling the ...
