美国国家航空航天局(NASA)的科学家们最近又拿出新证据,证明地球的邻居火星上的确曾有生命存在:他们从1.3万年前落到地球上的一块火星陨石中发现了简单细菌的石化.这个消息也许能给怀有移民火星梦想的人们增添一份信心.据媒体报道,科学家们的新证据是从一块1984年在南极洲发现的火星陨石中找到的.据介绍,这块被命名为艾伦·希尔斯84001的陨 相似文献

像一些影视剧描述的情况一样,当某地发生凶杀案后,法医和警察会立即奔赴现场收集各种证据,不放过任何“痕迹证据”。不过,有一些重要的证据是肉眼根本看不到的,比如说细菌,它现在可是破案的利器。 相似文献

证据展示是在庭审前控辩双方交换证据、相互获取有关案件信息的制度。旨在“整理争点” ,增加对抗 ,体现公正 ,兼顾效率。司法实践中 ,控方从法院“交换”取得辩方展示的拟在法庭出示的证据后 ,以核实为名 ,进行反调查 ,又获取与辩方观点相反的新证据 ,并运用于诉讼。这种旨在达到自己诉讼目的而违背刑事诉讼原理 ,破坏法定程序 ,影响客观、公正 ,降低诉讼效率的做法 ,应引起我们的深思。 相似文献

Research increasingly recognises the importance of student bystander and adult educator shared responsibility for successful bully prevention. The role of teacher observations versus student reports of bullying, as well as staff preparedness, as predictors of teacher involvement was investigated in 115 middle school teachers. Being told by students about bullying incidents was the strongest predictor of teacher involvement. However, the relation between being told about bullying, or observing it, and coaching students on how to manage bullying was most evident when teachers felt highly prepared to handle bullying situations. Results from this study point to the pivotal role that both teacher preparedness and student reporting play in teacher responsiveness to bullying. Implications for training school professionals and bully prevention programmes are discussed. 相似文献

The compelling argument for harassment prevention training: Implications for instructional designers
John A. Sample 《Performance Improvement》2007,46(7):18-26
The purpose of this article is to inform instructional design and development specialists on the importance of harassment prevention training in organizations. The review includes a summary of relevant case law, a review of litigation costs associated with harassment litigation, and the value of return on investment for such instruction. Good‐faith effort as a strategy to avoid litigation and punitive damages is emphasized. Recommendations for designing and implementing harassment prevention instruction are proposed. 相似文献

In the hit BBC TV drama Life on Mars Sam Tyler had an accident and woke up in 1973. Is he mad, in a coma or actually back in time? As the drama unfolds he experiences a world without performance audits but also one without the safeguards for arrest, detention and the interviewing of suspects mandated by the Police and Criminal Evidence Act (1984). The acclaimed series has led to flights of nostalgia, not least for a world in which police could get on with ‘real policing’ without ‘unnecessary’ paperwork. In this article, we will metaphorically go back in time to contemporary and historical practices of headship in English schools. If a headteacher from 2009 were to wake up in 1973 what would they understand about their work, what would be the same, what would be different? What taken‐for‐granted current practices might get them into trouble, what might frustrate them – and what might delight them that they would bring back to the current job if they could? Mobilising Bourdieu’s thinking tools, we will examine these questions through an analysis of published and unpublished texts produced by heads about their work. 相似文献

火星文风靡整个网络,受到了年轻一代的极力推崇。从文字的角度来看,火星文是一种以汉字(包括简体字、繁体字)为主体,融合了外文、台湾注音符号、字母、数字、图形以及其他符号的文字综合体。火星文的使用呈现出创新性与离奇性并存、简略性与复杂性并存、多样性与不规范性并存的特点。 相似文献
