This paper discusses and illustrates various approaches for the longitudinal analysis of personal networks (multilevel analysis, regression analysis, and SIENA). We combined the different types of analyses in a study of the changing personal networks of immigrants. Data were obtained from 25 Argentineans in Spain, who were interviewed twice in a 2-year interval. Qualitative interviews were used to estimate the amount of measurement error and to isolate important predictors. Quantitative analyses showed that the persistence of ties was explained by tie strength, network density, and alters’ country of origin and residence. Furthermore, transitivity appeared to be an important tendency, both for acquiring new contacts and for the relationships among alters. At the network level, immigrants’ networks were remarkably stable in composition and structure despite the high turnover. Clustered graphs have been used to illustrate the results. The results are discussed in light of adaptation to the host society. 相似文献

This paper examines how education and family background affect the fertility plans of young individuals in Mexico. Quantile
regression for count data is used for the analysis. Results indicate that education and family structure affect planned fertility
only at the tails of the conditional distribution. Education reduces planned fertility only among women with relatively strong
preferences towards children. An absent father reduces planned fertility mostly at the bottom of the conditional distribution.

This paper presents a model of service process for a family support service at the preventative level as part of a wider debate about child welfare systems in the UK and beyond. The paper places the debate about the shape of preventative family support services within the policy context and uses it to critique various models of service provision, principally the ‘child rescue’ paradigm. From this, the paper explores the characteristics that constitute a complex, yet preventative, family support service. This model is then illustrated using empirical evidence collected from the evaluation of a voluntary and community sector project in the North West of England that describes the service process and some of its characteristics. The paper argues that the model of family support presented has implications for the type of service process that can effectively put the theory into practice. Finally, questions for further research are defined in relation to the implications that this model poses for professional–user relationships and for the professional forms that can deliver preventative family support. 相似文献

This paper is about an evaluation of three centre-based projects established by a voluntary organization under the Scottish Government's Youth Crime Prevention Fund, to work with primary school-aged children displaying challenging and antisocial behaviour. Following a brief overview of what is known about effective interventions, the paper describes the projects' ways of working, including their remit and ethos. The core intervention chosen was the well-tested Webster-Stratton training programme, The Incredible Years . Wrap around services were also developed and staff modelled the projects' ethos, promoting children's participation and parents' empowerment. The evaluation is described, noting the limited time and resources at the disposal of the evaluation team. The evaluation team adopted a broad definition of evidence, using a range of measures to explore the processes of project development and service intervention, the meaning to the children and families who used the services, and the impact on children's behaviour and parents' levels of stress. The results were modest but encouraging. They suggested that the projects had provided valuable turning points for some of the children with out-of-control behaviour and their families. Finally, it is suggested that a better way to evaluate such projects could be to use complexity theory 相似文献

Summary. We consider joint spatial modelling of areal multivariate categorical data assuming a multiway contingency table for the variables, modelled by using a log-linear model, and connected across units by using spatial random effects. With no distinction regarding whether variables are response or explanatory, we do not limit inference to conditional probabilities, as in customary spatial logistic regression. With joint probabilities we can calculate arbitrary marginal and conditional probabilities without having to refit models to investigate different hypotheses. Flexible aggregation allows us to investigate subgroups of interest; flexible conditioning enables not only the study of outcomes given risk factors but also retrospective study of risk factors given outcomes. A benefit of joint spatial modelling is the opportunity to reveal disparities in health in a richer fashion, e.g. across space for any particular group of cells, across groups of cells at a particular location, and, hence, potential space–group interaction. We illustrate with an analysis of birth records for the state of North Carolina and compare with spatial logistic regression. 相似文献

In 2008 the authors held "Involving Interface," a lively interdisciplinary event focusing on issues of biological, sociocultural, and technological interfacing (see Acknowledgments). Inspired by discussions at this event, in this article, we further discuss the value of input from neuroscience for developing robots and machine interfaces, and the value of philosophy, the humanities, and the arts for identifying persistent links between human interfacing and broader ethical concerns. The importance of ongoing interdisciplinary debate and public communication on scientific and technical advances is also highlighted. Throughout, the authors explore the implications of the extended mind hypothesis for notions of moral accountability and robotics. 相似文献

Empirical evidence has consistently shown that political participation is positively related with socioeconomic background. Furthermore, recent research suggests that children who come from low status families are already less willing to get politically involved. The present paper aims to analyze the possible impact that schools can have in mitigating the effect of parents' socioeconomic status on students' expected electoral participation, focusing on two variables: civic knowledge and classroom climate. The analyses are based on a series of multilevel models using Chilean data of the International Civic and Citizenship Education Study 2009. The results support the influence of students' socioeconomic background on expected electoral participation. Furthermore, civic knowledge and classroom climate show a positive and similar influence on students' expected participation. However, classroom climate appears less affected by students' background than civic knowledge, opening the discussion about which strategy should be emphasized when aiming to mitigate the political participation gap. 相似文献

The development of initiatives for Local Agenda 21 for the cities of Peru, their documentation for the “best practices” programme of HABITAT II, and the demand for a formalized programme of support, capacity building and technical assistance has stimulated the establishment of the Peru Urban Management Education Programme (PEGUP). The PEGUP represents an innovative approach to capacity building, working through different mechanisms of education and training, technical assistance to municipal development of Local Agenda 21 and the promotion of networking and experience exchange. The experiences to date indicate that the set of support mechanisms is in line with the requirements of local governments which need a variety of support on the long road to develop urban management capacities that allow the solution of their urban and environmental problems. PEGUP offers a variety of services which are part of the development strategy of “Forum of Cities for Life” network. 相似文献
