Estudo comparativo da área ocupada pelos corpos pedunculados no cérebro de duas espécies de abelhas (Hymenoptera, Apoidea) Zoologia
Abdalla,Fábio Camargo; Cruz-Landim,Carminda da.
The present study compare the size of the corpora pedunculata (mushroom bodies) of Exomalopsis aureopilosa a quasi-social specie and Apis mellifera a eusocial specie of bees. The aim was to correlate the developmental degree of such structures with the behavior complexity. The results show that the female specimens of both species have the corpora pedunculata with same relative size. However the area occupied by the neurones cellular bodies (glomeruli) is greater in the workers of A. mellifera. In other way in E. aureopilosa the total size of the corpora pedunculata is larger in females, but the glomeruli area is relatively larger in the male.

Gender Inequality in India: Evidence from a Rural Survey in West Bengal AgEcon
Tisdell, Clement A..
Notes the unfavourable female-male ratio in India and its declining trend. In addition, the convergence of this ratio for the scheduled castes towards that of the general casts is noted as well as the slight decline in this ratio for scheduled tribals. A reason for this trend is suggested. Gender inequality is explored by summarising the results of survey of wives in the Midnapore area of West Bengal. Wives in four villages were interviewed so as to include tribals (Santals) and non-tribals, all of whom were Hindus. The socio-economic characteristics of those interviewed are first summarised and general information provided about the survey. The results are then used to consider several aspects of inequality in relation to sons and daughters, to gauge the...
