Crime, medo e percepções de insegurança

O artigo é produto de três pesquisas de vitimização realizadas em Marília/SP, entre os anos de 2001 e 2008, com o objetivo de conhecer a dinâmica do crime sob a ótica da vítima real (objetiva) e captar os sentimentos de medo do risco “potencial” da população (vítima ou não). O primeiro caso – vítima real – constitui um instrumento auxiliar ao desenvolvimento de programas de prevenção mais eficazes por abranger, inclusive, os crimes subnotificados. De modo geral, os resultados contribuirão para a compreensão de alguns aspectos da dinâmica criminal, da relação entre a polícia e a comunidade, da percepção do medo e da sensação de (in)segurança.

Allonursing in river buffalo, Bubalus bubalis: Nepotism, incompetence, or thievery?

Allonursing was investigated in a dairy herd of 30 river buffalo cows and their calves. The primary behavioural variables were solicitations of allonursing by calves and acceptances of calves by cows. The sample of cows included a group of nine half-sisters, two additional pairs of half-sisters, and a pair of full-sisters. All of the calves were half-siblings owing to putative common paternity. Ancillary variables were age, milk-yield and docility of cows, as well as age, sex, weight and growth rate of calves. Three hundred and fifty-one instances of allonursing and 341 of filial nursing were recorded. There were large individual differences in the cows' tendencies to accept their own offspring and non-filial calves, and for the calves to successfully solicit milk from their mothers and other cows. Thirteen of the 30 cows accounted for 97% of the allonursing. Frequent allonursing was correlated with decreased growth rate in the donors' calves. Allonursing was unrelated to kinship or reciprocal relationships among the cows, and was associated with a lack of maternal experience in young cows and apparent milk theft by hungry calves whose mothers were not providing them with sufficient milk. © 1995 The Association for the Study of Animal Behaviour.
