Males generally use aggression more often than females. However, the magnitude of difference between the sexes varies widely
according to the type of aggression that is considered, and according to the developmental period studied. Taking a developmental
perspective, this paper reviews research that compares the progression of physical aggression (predominantly used by males)
with indirect aggression (predominantly used by females) among males and females. Existing empirical evidence indicates that
most children cease to use physical aggression during the course of childhood, but that a minority fails to do so. This group
is comprised of children with high, stable levels of PA and is mostly male. Overall, most children use low levels of IA, but
there is one group that uses this type of aggression with increasing frequency. This group is mostly female. Importantly,
the differences between the sexes are not stable over time. Rather, while the gap between males and females is present during
preschool years, it widens considerably during childhood and preadolescence. A review of hypotheses based on evolution, biology
and social learning provides critical insight into the origins and development of sex differences in aggression over the life
course. We conclude by arguing that violence in males may be effectively reduced through early, sustained intervention with
high-risk mothers. 相似文献

This paper looks at the field of information technology (IT) law and its reliance on the buzzwords, jargon and acronyms that tend to alienate serious discussion about some of the deeper socio‐legal issues involved. It is often easy to become confused by the terminology and the technology, which has led to some non‐issues receiving too much interest (the year 2000 bug for example) and some valuable and worthy topics being almost ignored. Some writers and researchers may be tempted to neglect the field because of a lack of understanding of the technology, which may eventually lead to the end of IT law as a serious field of research. This paper will attempt to re‐ignite the jurisprudential debate about the future of IT law research, teaching and practice by looking at the possible trends emerging from the literature. 相似文献

The aim of this work was to study taphonomic marks that cadaveric coleopteran can produce under controlled conditions. To evaluate this, pig trotters were initially exposed to adults of Dermestes maculatus De Geer at 21 ± 5°C and a 12:12‐h day/night cycle. Observations were made and photographs taken every 4–5 days for 9 months. When feeding and reproducing, D. maculatus produced, in both adult and larvae stages, different types of marks such as holes, striations, scratches, and pits in several kinds of tissue such as integumental, connective, and muscular, in both their fresh and dried stages. Bite marks were also evident. The results in this study provide not only taphonomic but also biological and forensic information. This is the first time that this kind of experiment has been performed. 相似文献
