ABSTRACT

This qualitative study investigates urban at-risk youths’ perspectives on their multiproblem situations and explores their needs for support. Semi-structured interviews were conducted with 23 at-risk youths with varied (externalizing) problems and risk factors. The data analysis was carried out using an inductive thematic approach. Four main themes emerged: desistance from delinquent behavior, need for self-reliance, negative experiences in social relationships and need for support. The participants indicated a strong need to be(come) self-reliant, which was visible in their statements on independence, coping with problems and reluctance to seek or accept help, also regarding desistance from crime. For some, this need for self-reliance seemed to be accompanied by distrust of others, which appeared related to previous negative experiences in social interactions. The participants seemed more open to support coming from someone with similar characteristics or experiences. The findings suggest that in helping at-risk youths, a delicate balance should be sought between stimulating autonomy and providing the necessary resources for support. A focus on strengthening factors that foster resilience is recommended. Future research could investigate the possible benefits of perceived similarity between youths and their care providers.  相似文献

Two spatial tasks were designed to test specific properties of spatial representation in rats. In the first task, rats were trained to locate an escape hole at a fixed position in a visually homogeneous arena. This arena was connected with a periphery where a full view of the room environment existed. Therefore, rats were dependent on their memory trace of the previous position in the periphery to discriminate a position within the central region. Under these experimental conditions, the test animals showed a significant discrimination of the training position without a specific local view. In the second task, rats were trained in a radial maze consisting of tunnels that were transparent at their distal ends only. Because the central part of the maze was non-transparent, rats had to plan and execute appropriate trajectories without specific visual feedback from the environment. This situation was intended to encourage the reliance on prospective memory of the non-visited arms in selecting the following move. Our results show that acquisition performance was only slightly decreased compared to that shown in a completely transparent maze and considerably higher than in a translucent maze or in darkness. These two series of experiments indicate (1) that rats can learn about the relative position of different places with no common visual panorama, and (2) that they are able to plan and execute a sequence of visits to several places without direct visual feed-back about their relative position.  相似文献
