When In Rome: Conformity and the Provision of Public Goods [PDF]
We ask whether conformity, copying the most observed behavior in a population, can affect free riding in a public goods situation. Our model suggests that, if free riding is sufficiently frequent at the start of a public goods game, conformity will ...

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Electron-magnon Umklapp Scattering in FePt Films Measured by Thermopower
We report unconventional thermopower (Seebeck coefficient, $S$) behavior of $L1_{0}$ FePt films. The electron diffusion and magnon scattering are found to be the major contributions to the thermopower at low temperatures. The temperature dependence of $S$

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Researching on Head Car Crashworthiness of Inter-city EMUs
With overall design ideas for crashworthy car body, referring to domestic and foreign crashworthiness design specifications and guidelines and combining with a certain inter-city EMUs, finite element models of inter-city EMUs head car collision were ...

ABSTRACT This paper reports on the excavation of a cache of stone artefacts, buried on the bank of a waterhole or ‘billabong’ in central western Queensland. This is an extremely rare find, and yet it is the second such site to be reported within less than a 10 km radius.

ABSTRACT The archaeological site Graman B4 provided one of the first records of substantial dietary change in ancient Australian Aboriginal society. Initial examination of the faunal remains from this site suggested that Late Holocene hunters reduced their focus on high‐ranked kangaroos to increasingly rely on arboreal possums; and that these ...

Experimental Testbeds for ECOSEL: A Market Framework for Private Provision of Forest Ecosystem Services [PDF]
We attempt to design a market framework (which we call ECOSEL) for private provision of forest ecosystem services. ECOSEL is a non-regulatory framework that uses a voluntary public good provision mechanism (in a form of an auction) in conjunction with a ...
