Interdependence of government expenditure among European countries: Productivity spillover and strategic interaction

Economic Inquiry, EarlyView.
Abstract We build an endogenous growth model that distinguishes productive and welfare government expenditures and embeds fiscal externalities. The model yields three testable hypotheses: (i) productive expenditure raises growth (Barro effect); (ii) productive expenditure generates cross‐country productivity spillovers; (iii) government expenditure ...

Locating nests of endangered bumble bees: Lessons from field trials in northern Germany

Insect Conservation and Diversity, EarlyView.
Tracking bumble bees to find their nests using coloured strips of paper stuck to their thorax proved to be the most suitable method, while radio transponders were too heavy. Tracking times of up to 2 h and distances of up to 800 m were achieved with strips of pink craft tissue paper.

Freight distribution optimization by implementing the team orienteering problem with occasional drivers

International Transactions in Operational Research, EarlyView.
Abstract This research evaluates the effectiveness of a hybrid crowdshipping system that integrates occasional drivers with traditional delivery services (OD+TD) to improve the efficiency of freight distribution. By implementing the team orienteering problem with occasional drivers model, we develop a mathematical model and an agile optimization ...

When Numbers Mean Money: Pest Precision Sampling in High‐Density Mango Crops

Journal of Applied Entomology, EarlyView.
ABSTRACT The development of sampling plans is essential for assertive decision‐making in integrated pest management programs. The present study aimed to develop a plan for monitoring major mango pests in high‐density mango crops in Brazil. For this purpose, the influence of the position of the branch to be sampled in the canopy (internal and external ...

Breeding 5.0: Artificial intelligence (AI)‐decoded germplasm for accelerated crop innovation

Journal of Integrative Plant Biology, EarlyView.
ABSTRACT Crop breeding technologies are vital for global food security. While traditional methods have improved yield, stress tolerance, and nutrition, rising challenges such as climate instability, land loss, and pest pressure now demand new solutions.
