Impact of Geography on Institutions in Agricultural and Nomadic Societies

open access: yesInternational Studies of Economics, EarlyView.
ABSTRACT How geography affects the choice of institutions is studied in a theoretical model. In this model, nations are located around a circle. Rulers compete through choosing tax rates, the level of military spending, and the degree of formality of institutions. Geographic condition is captured by population density.

Must Longtermists Wish Us All Dead? A Quadrilemma

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Longtermists assign great moral importance to making the long‐term future as good as possible, especially by ensuring the survival of humanity. We argue, to the contrary, that on assumptions that are plausible, conservative, or shared by leading longtermists, human extinction will likely augment total utility among human and non‐human animals ...

Biochemical and Molecular Insights Into Monocrotaline‐Induced Hepatotoxicity: An Experimental Mouse Study

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Monocrotaline (MCT), a plant‐derived pyrrolizidine alkaloid, is well known for its hepatotoxic effects. However, full elucidation of the mechanisms underlying MCT‐induced hepatotoxicity, as well as the development of reliable biomarkers for early detection and monitoring, requires an integrated evaluation of biochemical, molecular, and ...

Annual and Seasonal Rainfall Variability in Mozambique During the Nineteenth Century

open access: yesInternational Journal of Climatology, EarlyView.
This paper presents the first annually and seasonally resolved reconstructions of nineteenth‐century rainfall variability for Mozambique derived from the analysis of extensive documentary evidence. It reveals spatially heterogeneous rainfall patterns with recurrent multi‐year droughts, episodic extreme wet events, and a strong coherence between ...

‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...
