This paper investigates the mediation of the adoption of computerized accounting system （CAS） on the relationship between environmental uncertainty and organizational performance. The authors use factor analysis, path analysis, and regression model to examine the effects of CAS adoption on the relationship between environmental uncertainty and organizational performance. The findings reveal that the adoption level of CAS is positively associated with organizational characteristics, environmental uncertainty, and organizational performance, and the usage of CAS has a statistically significant mediating effect on the relationship between environmental uncertainty and organizational performance. This paper will be significant to business managers in the decision to adopt CAS.

Wogonin is a plant flavonoid compound extracted from Scutellaria baicalensis(Huang-Qin or Chinese skullcap) and has been studied thoroughly by many researchers till date for its anti-viral, anti-oxidant, anti-cancerous and neuro-protective properties. Numerous experiments conducted in vitro and in vivo have demonstrated wogonin's excellent tumor inhibitory properties. The anticancer mechanism of wogonin has been ascribed to modulation of various cell signaling pathways, including serine-threonine kinase Akt(also known as protein kinase B) and AMP-activated protein kinase(AMPK) pathways, p53-dependent/independent apoptosis, and inhibition of telomerase activity. Furthermore, wogonin also decreases DNA adduct formation with a carcinogenic compound 2-Aminofluorene and inhibits growth of drug resistant malignant cells and their migration and metastasis, without any side effects. Recently, newly synthesized wogonin derivatives have been developed with impressive anti-tumor activity. This review is the succinct appraisal of the pertinent articles on the mechanisms of anti-tumor properties of wogonin. We also summarize the potential of wogonin and its derivatives used alone or as an adjunct therapy for cancer treatment. Furthermore, pharmacokinetics and side effects of wogonin and its analogues have also been discussed.

Objective: To evaluate the efficacy of He-Ne laser in combination with topical clindamycin in the treatment of AV at 108 Military Central Hospital from Oct 2015 to Aug 2016. Subjects and Methods: 61 patients with AV were divided into 2 groups: Group 1: 31 patients were treated with He-Ne laser in combination with topical Clindamycin, Group 2: 30 patients were only treated with topical clindamycin. Laser HE-NE was applied 2 times/week for 6 weeks. Result: After 3 months of treatment Group 1: very good—51.6%, good—48.4%. Group 2: very good—30%, good—50% and moderate—20%. Conclusion: The combination of He-Ne laser with topical clindamycin shows more rapid clinical improvement compared to topical clindamycin alone in the treatment of mild and moderate AV.

幽默影响和丰富着我们的日常生活。幽默还反映出一个人对生活的态度、个性以及他对外界的看法。幽默因人而异,一个人发现有趣的东西对另一个人毫无乐趣。除了主观感觉外,语言和文化条件也起着重要作用。因为缺乏必要的社会文化背景,来自不同国家和文化的人有可能无法互相理解对方的幽默感。因此可以将幽默视为一个普遍的概念,即使大家不是为了同一回事而发笑,但人人都会发笑。幽默翻译因其强大的文化和语言特性而成为每位翻译都面临的一项挑战。一段时间以来,许多翻译学者甚至把幽默翻视为“不可能的任务”,这一观点深受源语和目的语文本对等这一过时理论影响,始终关注于翻译自由应走多远的问题。本文研究幽默翻译的难度。事实证明,它早已不再是不可翻译的主题。李劲的作品《别输在不会表达上》作为这次翻译项目的原文。从标题可以看出,李劲作品的题目涉及中国社会和文化中的修辞和沟通。本文的主要重点是为汉德幽默翻译的困难提出一种有普遍意义的方法和翻译策略。翻译的目标读者是对中国文化感兴趣,但对中国及其传统知识甚少了解的普通德国读者。因此,目的是为德语受众弥补缺失的源语文化背景,创建一个德语受众容易理解的翻译,使之更接近中国社会的幽默感和魅力。由于幽默在世界各地都不尽相同,更不用说在中国和德国两个截然不同的文化了,这里的重点是再现德语中的幽默元素,使目标受众因类似的效果或笑话的趣味而发笑,至少使译文具备合理的幽默感,使德语读者也能体会到其幽默之处。本文分为五个部分。引言之后是对作品内容的介绍,其中对文本的结构以及作者的语言或风格进行了详细说明。第三章论述了相关的理论原理。赖斯（Reiss）和费梅尔（Vermeer）的翻译理论被用作翻译实践的指南。在探讨幽默翻译的理论问题时,首先对幽默这一概念做了更仔细的研究,并使用定义进行讨论。接下来,对生成幽默的方法和提供可能的翻译策略进行了论述。具体而言,产生幽默的方法可分为笑话、嘲笑和讽刺、文字游戏。本章最后讨论了幽默的不可译性及其复杂性。在第四章的后续分析中,论文列出了极具挑战的原文段落,并提供了基于翻译策略的翻译过程示例和说明。第五章包含了本文在翻译实践中分析得出的所有发现和结论。
