The proliferation of information technology offers challenges to developing countries which struggle with basic human needs. Yet the key to their survival may lie in information which is inaccessible to them. Facing these challenges, developing nations start from a position of frailty based on low levels of capital; a limited information infrastructure; dependencies on foreign aid and multinationals; and an ever‐increasing population growth. It is essential that foreign technology inflow is adopted strategically within the pre‐existing framework of national policies for technological development and with an emphasis on technology transfer. The broad policy direction needs to be towards the establishment of an information infrastructure and a contingent perspective for the meta‐policy process of designing appropriate information technology infrastructures.

Objective
In the present randomized controlled trial, the effectiveness of multisystemic therapy (MST) in The Netherlands was examined. Moderator tests were conducted for ethnicity, age and gender.Methods
The sample consisted of N?=?256 adolescents, referred because of conduct problems, and randomized to MST or treatment as usual (TAU). Assessments (questionnaires and observational ratings) took place before and immediately after the treatment.Results
MST was more effective than TAU in decreasing externalizing behavior, ODD, CD and property offences, but not for violence. Findings were mixed for adolescents’ and parental cognitions: the MST group, compared to TAU, showed an improvement in parental sense of competence, and a decrease in adolescents’ hostility, but no change in self-esteem and an increase in personal failure. MST was effective for positive dimensions of parenting and associations with prosocial peers, but not for relationships with deviant peers. MST was equally effective for adolescents of different ages and with different ethnicities. However, MST showed larger (and more positive) effects for adolescent cognitions for boys than for girls.Conclusions
Effects of MST in The Netherlands are generally comparable to the positive findings reported in American and Norwegian trials. MST seems equally effective across age and ethnic minority groups, but some gender moderator effects were found for adolescent cognitions. 相似文献43.

This paper addresses several issues that we encountered when implementing a randomized experiment to evaluate a promising intervention for serious juvenile delinquents, multi-systemic therapy (MST). The issues overlap with issues others experienced when trying to conduct randomized experiments in clinical practice, but are complicated because MST takes place in a legal context. The complex juvenile justice system makes it difficult to come up with a simple system of randomization. Problems encountered are the complexity of the referral process in this type of intervention, legal issues and the ethical concerns raised by clinicians. Our experiences might be useful to others planning to carry out a randomized efficacy study within the juvenile justice system. Firstly, other researchers might feel supported if they realize that others experience similar problems, and, secondly, we provide some concrete suggestions concerning the following: selecting the procedures and determining the moment of randomization, dealing with and overcoming the resistance of institutions involved, maintaining the cooperation of both the institution and the sample, and keeping turnover of research staff to a minimum. 相似文献
