数据初始值对DF类IPS检验势的影响研究

 本文研究了DF类面板数据单位根IPS检验势受时序数据初始值的影响,推导了DF类面板单位根IPS检验统计量在局部备择假设下的极限分布和局部渐近势函数,发现了DF类面板数据单位根IPS检验统计量局部渐近势在异质性局部备择假设下是初始条件的单调递增函数;小样本Monte Carlo模拟分析结果表明,若假设初始条件为零,DF类IPS统计量的检验势将被低估。     

Implementation of evidence-based interventions: analyzing critical components for sustainability in community mental health services

This study analyses the implementation and sustainability of evidence-based community mental health services in the form of publicly financed Individual Placement and Support programs. Critical implementation components and program fidelity were assessed after one year. After two years, program fidelity was assessed once again. After three years, the programs’ sustainability was assessed and semi-structured interviews performed, in order to deepen the understanding of implementation. Interviews and documents provided the quantitative and qualitative data, which were analyzed by the use of the Supported Employment Fidelity Scale, the Sustainable Implementation Scale (which was developed in a connecting study), and qualitative content analysis. Despite promising fidelity results after one year, eight out of 14 programs were terminated within three years. Implementation of integrated evidence-based programs in community-based settings is a delicate undertaking. Implementing agencies can benefit from rigorous preparation before program start, especially concerning the circumstances at the organizational level, such as making plans for collaboration, financing and assessments of program fidelity.
