We investigated how group members achieve collective decision-making, by considering individual intrinsic behavioural rules and behavioural mechanisms for maintaining social integration. Using a simulated burrow environment, we investigated the behavioural rules of coordinated workload for soil distribution in a eusocial mammal, the naked mole-rat (Heterocephalus glaber). We tested two predicti...
Biological assays were used to evaluate the effect of the insect growth regulator fenoxycarb (ethyl (2-p-phenoxyphenoxy) ethyl carbamate) on production of queen-derived dealation inhibitory pheromone and the queen recognition pheromone of Solenopsis invicta Buren. Treated virgin and mated queens weighed less and were less capable of inhibiting dealation by female alates than were nontreated con...

The 8-puzzle is the largest puzzle of its type that can be completely solved. It is simple, and yet obeys a combinatorially large problem space of 9!=2 states. The N N extension of the 8-puzzle is NP-hard. In the rst part of this paper, we present complete statistical data based on an exhaustive evaluation of all possible tile con gurations. Our results include data on the expected solution len...
We investigated worker policing by egg eating in the ponerine ant Pachycondyla inversa, a species with morphologically distinct queens and workers. Colonies were split into one half with the queen and one half without. Workers in queenless colony fragments started laying unfertilized male eggs after three weeks. Worker-laid eggs and queen-laid eggs were introduced into five other queenright col...

Spatial skills have been associated with learning in STEM areas and some research has shown that playing video games could facilitate the development of spatial skills. This study examines whether playing a game that uses a realistic physics engine and places spatial demands on the players could facilitate learning a subsequent physics lesson. Fifty-eight participants viewed a brief lesson on N...
The 8-puzzle is the largest puzzle of its type that can be completely solved. It is simple, and yet obeys a combinatorially large problem space of 9!/2 states. The N x N extension of the 8-puzzle is NP-hard. In the first part of this paper, we present complete statistical data based on an exhaustive evaluation of all possible tile configurations. Our results include data on the expected solutio...
