交际策略的教学与运用

语言交际教学法的目的是提高学习者的交际能力。然而 ,作为交际能力的一个重要组成部分———策略能力 ,却被教师们忽略。交际策略的可教性依然是个有争议的问题。本文首先陈述交际策略的重要性 ,以便唤起教师的注意力 ;其次 ,分析影响学习者交际策略使用的因素 ;第三部分提出了交际策略的教学方法     

信息网络与高校学生思想政治工作

信息网络的发展,给高校学生思想政治工作带来严峻的挑战,同时也带来了难得的机遇。笔者认为:高校应该以新的教育理念和工作方法,占领网络思想教育阵地,积极推进思想政治教育进网络工作。     

阅读测验中认知与元认知策略研究

语言知识、策略能力和情绪等心理和社会特征在语言使用中交互作用,并对语言沟通能力产生影响。文章采用定量与定性方法对其预测性及内部关联加以实证。研究发现二者关联度很强,元认知策略对绩效预测力显著强于认知策略。认知与元认知策略呈现相互嵌套模式,相同加工行动在不同情境中由于履行功能差异而转换角色。     

Expected sample moments of concomitants of selected order statistics

In this paper, the task of determining expected values of sample moments, where the sample members have been selected based on noisy information, is considered. This task is a recurring problem in the theory of evolution strategies. Exact expressions for expected values of sums of products of concomitants of selected order statistics are derived. Then, using Edgeworth and Cornish-Fisher approximations, explicit results that depend on coefficients that can be determined numerically are obtained. While the results are exact only for normal populations, it is shown experimentally that including skewness and kurtosis in the calculations can yield greatly improved results for other distributions.     

庭审会话中的言语策略和权力控制--律师-证人庭审会话分析

在庭审特殊的语境下,参与会话的角色之间的权力分配是不均等的,法官的权力最高,其次是律师,其掌握着庭审会话的主动权,而证人只是被询问的一方,其权力极为有限,所拥有的言语权也最少。通过分析询问中律师一证人间的会话发现,律师借助封闭性问话、重复问话等言语策略对证人实施权力控制。同时,证人除在言语上对律师表示尊重外,也努力通过各种应答言词策略争取更多的主动权。两者之间对权力的控制主要表现在他们不同的言语策略上。     

数字技术对文化产业内容生产的挑战及其应对策略

数字技术当前深度参与文化产业的内容生产,对创作群体、生产活动、传播形式和消费语境等多方面皆产生重大影响,形成了全新的数字文化产业生态。然而,有些数字文化产品过于强调技术而忽视文化的特殊性,导致出现内容生产粗糙随意、价值判断标准矮化、意识形态风险增加等问题,不能稳定地输出品位高、社会效益佳的文化产品,未来发展面临挑战。对此,数字文化产业的内容生产需要打破“注意力经济”的单一模式、改良人工智能算法的激励与推荐机制、探索文化生产评价标准的自我更新,从而推动新时代数字文化产业的高质量发展。     

Basic aspects of evolution strategies

Evolution strategies (ESs) are a special class of probabilistic, direct, global optimization methods. They are similar to genetic algorithms but work in continuous spaces and have the additional capability of self-adapting their major strategy parameters. This paper presents the most important features of ESs, namely their self-adaptation, as well as their robustness and potential for parallelization which they share with other evolutionary algorithms.Besides the early (1 + 1)-ES and its underlying theoretical results, the modern ( + )-ES and (, )-ES are presented with special emphasis on the self-adaptation of strategy parameters, a mechanism which enables the algorithm to evolve not only the object variables but also the characteristics of the probability distributions of normally distributed mutations. The self-adaptation property of the algorithm is also illustrated by an experimental example.The robustness of ESs is demonstrated for noisy fitness evaluations and by its application to discrete optimization problems, namely the travelling salesman problem (TSP).Finally, the paper concludes by summarizing existing work and general possibilities regarding the parallelization of evolution strategies and evolutionary algorithms in general.     

What's wrong with sociology? Its public image

In response to editor Stephen Cole's question—"What's wrong with sociology?"—the answer is nothing that cannot be overcome by clearer communications and better public relations. The problem is that the field is not held in high esteem by college administrators, legislators, and the public. Many see us as rebels of the 1960s, political liberals, and impractical thinkers with a penchant for jargon. Even our research is derided by some as a waste of money. The solution consists of strategies for overcoming our poor public image. Seven strategies for doing so are discussed: (1) Write clearly. (2) Write for a mass audience. (3) Seek board positions. (4) Strengthen our identity. (5) Teach sociology in high school. (6) Develop academic partnerships. (7) Emphasize outcomes: increase in tolerance and research skills.

绘本游戏阅读活动开展的意义及其指导策略

游戏式阅读活动旨在充分发挥绘本中的游戏精神和教育价值,让幼儿在获得充分的游戏体验的同时,促进其各种能力的发展。教师在游戏式阅读活动中指导的关键在于能否正确看待绘本中的游戏精神与教育价值,满足幼儿“阅读游戏”的体验,把握“游戏式阅读”的指导要点,避免陷入重知识传授、轻游戏体验的教学误区。
