We tested the hypothesis that intergenerational effects of parents’ war trauma on offspring's attachment and mental health are mediated by psychological maltreatment. Two hundred and forty children and their parents were sampled from a war-prone area, Gaza, Palestine. The parents reported the number and type of traumatic experiences of war they had had during their lifetime before the child's birth and during a current war when the child was 10–12 years old. The children reported their war traumas, experiences of psychological maltreatment, attachment security, and symptoms of posttraumatic stress (PTSS), depression, and aggression. The direct and indirect intergenerational effects of war trauma were tested in structural equation models. The hypotheses were confirmed for father's past war exposure, and disconfirmed for mother's war exposure. The father's past war trauma had a negative association with attachment security and positive association with the child's mental health problems mediated by increased psychological maltreatment. In contrast, the mother's past war trauma had a negative association with the child's depression via decreased psychological maltreatment. The mother's current war trauma had a negative association with the child's depression and aggression via decreased psychological maltreatment. Among fathers, past war exposure should be considered as a risk factor for psychological maltreatment of children and the associated attachment insecurity and mental health problems. Among mothers, war exposure as such could be given less clinical attention than PTSS in the prevention of psychological maltreatment of children. 相似文献

This article describes the pedagogical framework of an interdisciplinary and international project entitled NINTER (Networked Interaction: Theory-Based Cases in Teaching and Learning). The practical aim of the project is to produce a pedagogical model for learning and teaching in networked environments. The research project has its foundation on socio-constructivist learning theories, with one of the most important principles being the idea of apprenticeship in thinking. The article also takes a look at the first results obtained from different kinds of videotaped and written material that were collected during a WWW-based university course. Also questions raised from the data for future research are considered. 相似文献

We investigated age-related differences in the relationships among acceleration, maximum running speed, and repeated-sprint performance in 61 highly trained young male soccer players (Under 14, n = 14; Under 16, n = 22; Under 18, n = 25). We also examined the possible influence of anthropometry (stature, body mass, fat-free mass) and biological maturation (age at peak height velocity) on performance in those three sprint-running qualities. Players were tested for 10-m sprint (acceleration), flying 20-m sprint (maximum running speed), and 10 × 30-m sprint (repeated-sprint performance) times. Correlations between acceleration, maximum running speed, and repeated-sprint performance were positive and large to almost perfect (r = 0.55-0.96), irrespective of age group. There were age-based differences both in absolute performance in the three sprint-running qualities (Under 18 > Under 16 > Under 14; P < 0.001) and when body mass and fat-free mass were statistically controlled (P < 0.05). In contrast, all between-group differences disappeared after adjustment for age at peak height velocity (P > 0.05). The large correlations among acceleration, maximum running speed, and repeated-sprint performance in all age groups, as well as the disappearance of between-group differences when adjusted for estimated biological maturity, suggest that these physical qualities in young highly trained soccer players might be considered as a general quality, which is likely to be related to qualitative adaptations that accompany maturation. 相似文献
