优化国际语言服务环境背景下关于大学英语写作教学的若干反思

国际语言服务的水平直接体现了一个城市乃至国家的国际化程度,关系到一个城市或国家的国际形象和国际竞争力。随着中国与国际社会的交流日深,对既有自己的专业又具备一定的英语综合运用能力的复合型人才的需求也随之增加。他们不但要有一定的英语口头表达能力,书面表达能力也面临着新的挑战和要求。但我国高校的大学英语课普遍对写作环节重视不足,导致学生的写作基础薄弱。文章分析了大学英语写作过程中存在的普遍性问题并提出了相应的对策。     

金代宗室管理制度考论

金朝十分重视对宗室的管理,设专门管理机构大宗正府,职掌修撰玉牒、监察训导宗室、宗庙祭祀等宗室事务;宗正官基本上由宗室属亲者担任,但也适当参用世戚勋旧。另有御史台、太常寺以及其他相关机构也兼理宗室事务。这些兼管机构与大宗正府相互配合,各司其职,从不同方面实施对宗室的有效管理。鉴于宗室也是威胁皇权的重要因素,金朝统治者对宗室还采取了诸多政令上的防范措施。     

微博时代我国主流意识形态面临的发展格局、挑战及其对策

微博时代,我国主流意识形态面临的机遇和挑战并存。微博的迅猛发展和强大功能,进一步拓展了我国主流意识形态的发展空间,深刻地改变了我国主流意识形态的发展格局。同时,微博也成为各种意识形态争夺的阵地;微博蕴含的政治力量挑战了国家的政治议程;微博谣言泛滥消弱了民众对我国主流价值观的认同。这些都给我国主流意识形态建设带来严峻的挑战。对此,我国主流意识形态必须有所作为,对微博的负面效应进行有效的制度化解和积极应对,确保我国主流意识形态建设稳定、持续、健康的发展。

试论问责制的法制环境与配套措施建设

问责制是对政府的违法行为及其后果都必须和能够追究责任的一种制度,构建合理的问责制,必须从法制环境与配套措施建设的角度入手,通过追究官员确实应承担的责任,促使官员合法、正当地行使手中的权力,不断提高管理水平,使行政机关和公务员真正负起责任。     

我国商会预防和应对对华反倾销诉讼的策略及措施

近年来,在国外我国产品被控反倾销的次数不断增多,而相比之下,胜诉案件的比例却没有同等增长,这对我国的出口贸易秩序和出口贸易发展造成极为不利的影响.商会应利用其自身优势,确定应对对华反倾销诉讼的策略,并采取相应的具体措施,积极参与对华反倾销诉讼活动的各个环节,进而改变预防和应对对华反倾销的各种被动局面.     

Comparison of performance measures for multivariate discrete models

For multivariate probit models, Spiess and Tutz suggest three alternative performance measures, which are all based on the decomposition of the variation. The multivariate probit model can be seen as a special case of the discrete copula model. This paper proposes some new measures based on the value of the likelihood function and the prediction-realization table. In addition, it generalizes the measures from Spiess and Tutz for the discrete copula model. Results of a simulation study designed to compare the different measures in various situations are presented.     

Deciding with Thresholds: Importance Measures and Value of Information

Risk‐informed decision making is often accompanied by the specification of an acceptable level of risk. Such target level is compared against the value of a risk metric, usually computed through a probabilistic safety assessment model, to decide about the acceptability of a given design, the launch of a space mission, etc. Importance measures complement the decision process with information about the risk/safety significance of events. However, importance measures do not tell us whether the occurrence of an event can change the overarching decision. By linking value of information and importance measures for probabilistic risk assessment models, this work obtains a value‐of‐information‐based importance measure that brings together the risk metric, risk importance measures, and the risk threshold in one expression. The new importance measure does not impose additional computational burden because it can be calculated from our knowledge of the risk achievement and risk reduction worth, and complements the insights delivered by these importance measures. Several properties are discussed, including the joint decision worth of basic event groups. The application to the large loss of coolant accident sequence of the Advanced Test Reactor helps us in illustrating the risk analysis insights.     

Comparing mean ranks for repeated measures data

Rank tests are considered that compare t treatments in repeated measures designs. A statistic is given that contains as special cases several that have been proposed for this problem, including one that corresponds to the randomized block ANOVA statistic applied to the rank transformed data. Another statistic is proposed, having a null distribution holding under more general conditions, that is the rank transform of the Hotelling statistic for repeated measures. A statistic of this type is also given for data that are ordered categorical rather than fully rankedo Unlike the Friedman statistic, the statistics discussed in this article utilize a single ranking of the entire sample. Power calculations for an underlying normal distribution indicate that the rank transformed ANOVA test can be substantially more powerful than the Friedman test.     

优势互补,协力合作开发——中俄双方联合开发抚远三角洲的问题研究

随着中俄两国在抚远三角洲国界线走向勘界工作的结束,两国地方政府便将抚远三角洲的开发建设提上重要议事日程。抚远三角洲独特的地缘优势使中俄双方在抚远三角洲开发建设上具有极强的互补性。因此,中俄双方遵循互利双赢的原则,不断完善合作协调机制,大力发展在能源、资源、农业、科技及旅游业等方面的协力合作,共同将抚远三角洲打造为区域开放合作的大平台。
