OBJECTIVE: Children who are physically maltreated are at risk of a range of adverse outcomes in childhood and adulthood, but some children who are maltreated manage to function well despite their history of adversity. Which individual, family, and neighborhood characteristics distinguish resilient from non-resilient maltreated children? Do children's individual strengths promote resilience even when children are exposed to multiple family and neighborhood stressors (cumulative stressors model)? METHODS: Data were from the Environmental Risk Longitudinal Study which describes a nationally representative sample of 1,116 twin pairs and their families. Families were home-visited when the twins were 5 and 7 years old, and teachers provided information about children's behavior at school. Interviewers rated the likelihood that children had been maltreated based on mothers' reports of harm to the child and child welfare involvement with the family. RESULTS: Resilient children were those who engaged in normative levels of antisocial behavior despite having been maltreated. Boys (but not girls) who had above-average intelligence and whose parents had relatively few symptoms of antisocial personality were more likely to be resilient versus non-resilient to maltreatment. Children whose parents had substance use problems and who lived in relatively high crime neighborhoods that were low on social cohesion and informal social control were less likely to be resilient versus non-resilient to maltreatment. Consistent with a cumulative stressors model of children's adaptation, individual strengths distinguished resilient from non-resilient children under conditions of low, but not high, family and neighborhood stress. CONCLUSION: These findings suggest that for children residing in multi-problem families, personal resources may not be sufficient to promote their adaptive functioning.  相似文献

ABSTRACT

Population aging is exacerbating the loss of competences in the workforce and simultaneously young people neither in employment nor in education and training (NEETs) are struggling to be reengaged in employment. These issues, which are deemed priorities for the European policy agenda, could be addressed by triggering active aging dimensions, valuing and exploiting older adult entrepreneurs’ knowledge for enhancing youngsters’ entrepreneurial attitudes, through mentoring. This paper reports the results of a study based on an intergenerational learning program, carried out in 2018 in Germany, Italy and Slovenia. The study was aimed at developing and testing one training on mentoring addressing 41 older adult entrepreneurs (55 and over), and two intergenerational learning trainings aiming at boosting entrepreneurial competences of 33 NEETs (aged 18–29). The impact of the program on older adult entrepreneurs and NEETs was assessed through a pre and post-evaluation using qualitative and quantitative tools. Findings at country level were treated as national case-studies and then the latter were compared by considering them as a multiple embedded case-study. Results indicated that, to different extent in the study countries, mentors learned and enhanced mentoring competences, e.g. active listening and the capability of orienting, improved well-being and self-esteem, social inclusion and active aging attitude. Moreover, NEETs acquired entrepreneurial and socio-relational competences by benefiting from the full exploitation of mentors’ know-how and the trust relationship with them. Companies, trade unions, educational and voluntary organizations should cooperate to adopt intergenerational learning programs as good practices for older adults and NEETs’ lifelong learning promotion.  相似文献

With a relatively complex maze, reliable forgetting is clearly seen when the training-test interval is 25 days. This forgetting is evidenced by the longer time taken to run the maze and in an increase in the number of errors from the last training trial to the first test trial. In this case, forgetting is a lapse, not a loss, since performance attains the last training trial level at a subsequent test. Furthermore, a reminder which does not in itself contain sufficient information to facilitate performance of a naive animal, significantly improves maze performance of animals which have “forgotten,” even on the first retention test. With the use of additional control groups, it is shown that there must be a memory lapse before contextual cues can be demonstrated to be effective in facilitating memory retrieval.  相似文献

A fairly recent definition of reading disability (RD) is that in the form of a hybrid model. The model views RD as a latent construct that is manifested through various observable unexpected impairments in reading-related skills and through inadequate response to intervention. The current report evaluated this new conceptualization of RD from an etiological perspective. The sample consisted of 2,737 twin pairs in 1st through 4th grade (Mage = 8.52) from the Florida Twin Project on Reading. Using twin analyses, results showed that a substantial proportion of genetic variance, a small proportion of shared environmental, and a small proportion of nonshared environmental variance was attributed to the RD factor. Findings suggest that the etiological architecture of RD closely mirrors the structure of the hybrid model of RD.  相似文献

Nowadays, meaningful learning takes a central role in science education and is based in mental models that allow the representation of the real world by individuals. Thus, it is essential to analyse the student’s mental models by promoting an easier reconstruction of scientific knowledge, by allowing them to become consistent with the curricular models presented in the classroom. In this context, the study aims to examine, through the application of a diagnostic instrument (Two-Tier Diagnostic Test), what students consider to be the seismic effects on soils and buildings, to analyse and to compare their mental models about some of these issues related to seismology, applying a questionnaire to 52 students from a Portuguese University attending an undergraduate degree in Geology and a master course in Biology and Geology teaching. The analysis of the data allowed concluding that undergraduate students have more inconsistent mental models than master students, mainly concerning the factors which influence the seismic risk, such as hazard and vulnerability, and the soils characteristics which influence the intensity of earthquakes. During their academic formation in the university, teachers present some curricular models to students which allow them to reconstruct their mental models and turn them scientifically consistent, enhancing the educational implications of this study that points to the need for teachers to be aware of the importance of the diagnosis of the students’ mental models and to promote meaningful learning and scientific literacy autonomously and dynamically.  相似文献

To investigate the relationship between achievement and IQ in the learning-disabled (LD) population, changes in the IQ scores of LD students from the early elementary grades to the high school grades were studied. The intercorrelations among those IQ scores and a variety of achievement scores were then explored for the purpose of ascertaining causal relationships. The results were interpreted as support for the contention that the underachievement of LD students (in particular, reading underachievement) plays a predominant causal role in the achievement-IQ relationship in this population.  相似文献

The ecological paradigm has become a powerful framework for understanding how teachers and students negotiate the learning environment. This article articulates the ecological paradigm into a more cohesive framework and expands it using influential work from the sociology of physical education. First, we explain several core concepts of ecological theory and explain how they fit together. Next, we overview past ecological work in each of the three main task systems, while integrating literature from outside traditional ecological theory to show how it better enhances the paradigm's usefulness. We show how culturally relevant content, student ownership/control, and cooperation/competition provide richness in further explaining the instructional task system. Similarly, we broaden the student social system into a social task system with three dimensions: relationships between teachers and students, relationships among students, and the social climate of the school.  相似文献

This article describes how the National Science Foundation's support of information research has evolved from NSF's original mission of improving the dissemination of scientific and technical information to its present interest in information robotics and intelligent systems. The pattern of grant support, since a major reorganization of the information science division in 1978, is analyzed in terms of the institutions, the investigators, and the disciplines that have been major grant recipients.  相似文献
