A systematic review on research trends and commercialised entomopathogenic nematodes: A global perspective

open access: yesAgricultural and Forest Entomology, EarlyView.
Out of 136 identified EPNs, only 18 (8 Steinernema and 6 Heterorhabditis) are commercialised globally, highlighting a major gap between discovery and application. High production costs and inconsistent field efficacy are the leading obstacles to the widespread commercialisation of EPN‐based biocontrol products.

Complementarity in alliances: How strategic compatibility and hierarchy promote efficient cooperation in international security

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.

The public agglomeration effect: Urban–rural divisions in government efficiency and political preferences

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Why and when do cities vote for the left? The emergence of the urban–rural divide in the United States in the 1930s is inconsistent with canonical theories of cleavages. This paper introduces an explanation: agglomeration effects. The provision of government services is more efficient in urban environments because of nonrivalries, economies of
