创新福建投资机制的对策与建议

分析福建目前经济增长呈现粗放式增长的若干表现：经济增长动力主要来自投资需求的扩张,投资外延化趋势明显,投资效益有待提高,用于科技进步和自主创新能力提高的投入依然不足,资源供需矛盾突出、对能源的依赖程度不断提高,经济增长伴随着环境恶化等现象。在此基础上,提出了从体制创新入手,转变经济增长方式,提高福建投资效率与内涵质量的基本思路。

福建省外商直接投资与经济增长关系的研究

20世纪80年代以来,国际资本流动日趋活跃,外商直接投资成为主要的资本流动方式,也成为发展中国家获取外部资源的主要渠道.根据福建省1985—2010年的年度经济数据,利用协整理论和Granger因果关系检验方法对福建省实际利用外商直接投资金额和GDP之间的关系进行实证检验,以检验福建的外商直接投资与经济增长是否存在长期均衡关系和因果关系,进一步把握福建省的经济发展模式的实质.     

Comfort drawing during investigative interviews: Evidence of the safety of a popular practice

Objective

This study evaluated the impact of comfort drawing (allowing children to draw during interviews) on the quality of children's eyewitness reports.

Methods

Children (N = 219, 5 to 12 years) who had participated in an earlier memory study returned 1 or 2 years later, experienced a new event, and described these events during phased, investigative-style interviews. Interviewers delivered the same prompts to children in the no drawing and drawing conditions but provided paper and markers in the drawing condition, invited these children to draw, and periodically asked if they would like to make another picture.

Results

Most children in the drawing condition were interested in using the materials, and measures of eyewitness performance were sensitive to differences in cognitive ability (i.e., age) and task difficulty (i.e., delay between the remote event and interview). Comfort drawing had no overall impact as evidenced by nonsignificant main effects of condition across 20 performance measures, although more of the younger children reported experienced touching in the drawing than no drawing condition.

Conclusions

The children successfully divided attention between voluntary drawing and conversations about past events. Importantly, comfort drawing did not impair the amount of information recalled, the accuracy of children's answers, or even the extent to which interviewers needed to prompt for answers. Due to the large number of analyses, the benefit of drawing for younger, touched children requires replication.

Practice Implications

Comfort drawing poses no documented risks for typically-developing school-aged children, but the practice remains untested for younger children and those with cognitive impairments.
