Ground rules directions are given to children in forensic interviews to explain what is expected of them, and to reduce their tendency to acquiesce to erroneous or incomprehensible questions. Ground rules may also be necessary when children provide testimony in court. Drawing on research conducted for the Australian Royal Commission into Institutional Responses to Child Sexual Abuse, the present study examined the use of ground rules directions delivered in court in 52 trials by 24 presiding judges in three jurisdictions to 57 child complainants (aged 7–17.5 years). Eleven categories of rules were identified. The number of words spoken to deliver each rule was counted, and grade-level readability scores were calculated as a proxy for the complexity of the ground rules. When judges asked comprehension or practice questions, the question types were coded. More than one third of the children (35%) received no ground rules directions from the judge; the remaining 65% received directions on an average of 3.5 types of ground rules out of a maximum of 11 types. While comprehension questions were common, practice questions were rare. Comprehension questions were most often presented in a yes/no format that implied the expected response, although this form of question is unlikely to provide an effective assessment of a child's comprehension. Neither the number of rules delivered nor the number of words used was related to children's age. Implications for children's court testimony are discussed. 相似文献

煤矿是我国国民经济的支柱产业之一。而采矿引起的一系列地质灾害不仅威胁矿区安全,而且影响和制约着经济的发展,从而引发一系列社会问题和矛盾。大同地区最主要的矿山地质灾害是以煤矿开采引发的地面塌陷。而遥感作为信息获取的快速、有效的工具,具有宏观性好、更新周期快、人为因素干扰小等优点,可以直接为地质灾害监测的决策者提供丰富的客观数据,还可以通过推理、演绎和归纳等科学方法,提炼出需要的科学数据,这样不仅丰富了地质灾害监测决策的技术手段,还大大提高了决策的效率。 相似文献

In recent years, the usages of by-products and wastes in industry have become more important. The importance of the sustainable development is also of increasing. The utilizations of wastes, as mineral admixture or fine aggregate, reduce the consumption of the natural resources and improve the durability of concrete. In this study, the effect of the fineness on the high temperature and sulphate resistances of concrete mortar specimens, produced with ground granulated blast-furnace slag (GBFS) replacing cement, is investigated. The compressive and flexural strength test results for all series related to durability effects, exposing temperature and solutions, exposure times for these durability effects, slag content and fineness are discussed. Conse- quently, the optimum slag contents are determined for producing the sulphate and high temperature resistant mortars. 相似文献
