《唐物语》中的王昭君故事在日本的演变

王昭君的故事在中国可谓家喻户晓、妇孺皆知,在日本古典文学史中也广为演绎和流传。成书于平安时代末期的《唐物语》第二十五篇就是王昭君故事在日本演变的产物。昭君故事中最核心的要素当属"画工曲笔",这一要素在《唐物语》中也有所体现。但是,在画工曲笔的契机和缘由,帝王与昭君及后宫嫔妃间感情纠葛的细腻描摹,以及昭君悲剧产生的根源等三个方面与中国原著的焦点截然不同。王昭君故事在日本的演变反映了日本天皇与后宫关系与中国的迥异。它融入了浓郁的日本本土文化色彩,为我们体悟两国风土人情的差异、把握日本文化提供了一种借鉴和思考。     

“河湟”地理概念变迁考

“河湟”这一地理概念,大致经历了汉代构建时期、唐代扩展时期和宋代以后复原时期三个阶段。汉代,随着中原王朝疆土西拓,“河湟”表述得以构建,但早期“河湟”内涵并不清晰;唐代,由于“河湟”地区本身战略地位的变化,“河湟”这一概念得到了进一步的扩展,其内涵更加的抽象化,指代的地域范围也更加的泛化和模糊;宋代以后,随着“河湟”边防地位的下降,其内涵也趋于向本体回归,最终成为今青海、甘肃两省黄河与湟水交汇区域的普遍代称。     

中国现代作家笔下的“南洋”风景:花木与建筑简

中国现代作家笔下有许多描写“南洋”风景的篇章,其中以“南洋”花木描写与“南洋”建筑描写卓为突出。诗人杜运燮的《热带三友》笔致动人地写述了“南洋”椰、蕉、木棉的尤异姿态和精神内涵。“南洋”的佛塔寺可谓“南洋”文化“超机体”的一个泛例隐喻,而新加坡的“鱼尾狮”则是“南洋”文化记忆库里最微缩典型的一个特案象征,两者分别从宏观与微观的代表性视界具体而微地诠证了“南洋”建筑风景全部文化归属性的“情感结构”。     

“一带一路”沿线东南亚国家林业资源开发

“一带一路”沿线东南亚国家森林资源丰富,是全球重要的热带木材产品出口地,但在片面的发展策略之下,森林滥伐对东南亚木材资源的可持续开发产生威胁,其中泰国的现代林业管理具有典型性。以泰国为研究案例,通过对其现代林业管理的沿革进行长时段梳理,分析其林业管理制度的特点和问题,探索总结东南亚国家的林业管理经验。研究认为,由国家垄断的林业管理方式是威胁泰国林业可持续发展的关键症结,导致片面追求林业经济利益而滋生腐败和过度采伐,引发社会矛盾,破坏了热带雨林生物多样性。研究还认为,社会自发的学术研究和公民保护行动对东南亚国家垄断的林业管理方式产生影响,形成了专门针对森林治理和环境保护的非政府组织（NGO）,推动了20世纪80年代以来东南亚的林业政策改革,缓解了破坏性开发带来的问题。因此,中国在与“一带一路”沿线东南亚国家的贸易和环境合作中,需要重视当地非政府组织的作用,积极参与亚太区域贸易合作,改善资源开发的整体环境。     

王国维“通人之学”与“专人之学”的尺短寸长

王国维“通人之学”“专人之学”等学术思想是中国学术研究转型的重大创新,通过对王国维学术成长的梳理、学术成果的分析、学术思想的论证,对“静安之学”进行了全面系统的研究。研究认为,王国维凭借厚实的知识贮备,批判地继承西方哲学理论与中国古代哲学思想,在构建中国大文科的学科体系、研究文史哲的学术体系和中国学者的学术话语体系方面做出了全面系统实践,取得重大进展和开创性成果,堪称开一代风气的大学者;王国维以创辟胜解、通方知类的学术思辨,创立二重证据方法,探索出一条由“通人之学”到“专人之学”学问研究蹊径。系统审读、反思静安之学,对我们严肃读书风气、匡正学问研究态度、提倡学术争鸣、甄别解决知识产权争端、清除学术造假现象、规范学术研究流程,能够起到见贤思齐、弃旧图新之作用。     

Marshall–Olkin gamma–Weibull distribution with applications

Abstract

A Marshall–Olkin variant of the Provost type gamma–Weibull probability distribution is being introduced in this paper. Some of its statistical functions and numerical characteristics among others characteristics function, moment generalizing function, central moments of real order are derived in the computational series expansion form and various illustrative special cases are discussed. This density function is utilized to model two real data sets. The new distribution provides a better fit than related distributions as measured by the Anderson–Darling and Cramér–von Mises statistics. The proposed distribution could find applications for instance in the physical and biological sciences, hydrology, medicine, meteorology, engineering, etc.     

Test for periodicity in restrictive EXPAR models

Abstract

This article is devoted to study the problem of test of periodicity in the restricted exponential autoregressive (EXPAR) model. The local asymptotic normality property, of this model, is shown via the adapted sufficient conditions due to Swensen (1985 Swensen, A.R. (1985). The asymptotic distribution of the likelihood ratio for autoregressive time series with a regression trend. J. Multivariate Anal. 16:54–70.[Crossref], [Web of Science ®] , [Google Scholar]). Using this result, in the case where the innovation density is specified, we obtain a parametric local asymptotic “most stringent” test.     

Adaptive Test for Periodicity in Self-Exciting Threshold Autoregressive Models

This article is devoted to the study of the periodicity testing problem in a self-exciting threshold autoregressive (SETAR) model. The local asymptotic normality (LAN) property is shown via the adapted sufficient conditions due to Swensen (1985 Swensen , A. R. ( 1985 ). The asymptotic distribution of the likelihood ratio for autoregressive time series with a regression trend . Journal of Multivariate Analysis 16 : 54 – 70 .[Crossref], [Web of Science ®] , [Google Scholar]). Moreover, the LAN of the central sequence is established. First, we consider the case where the innovation density is specified and we obtain a parametric local asymptotic test. Second, we construct an adaptive test in the case where this density is unspecified but symmetric. The performances of these established tests are shown via simulation studies.     

Use of the Correlation Coefficient with Normal Probability Plots

The use of the correlation coefficient is suggested as a technique for summarizing and objectively evaluating the information contained in probability plots. Goodness-of-fit tests are constructed using this technique for several commonly used plotting positions for the normal distribution. Empirical sampling methods are used to construct the null distribution for these tests, which are then compared on the basis of power against certain nonnormal alternatives. Commonly used regression tests of fit are also included in the comparisons. The results indicate that use of the plotting position p_i = (i - .375)/(n + .25) yields a competitive regression test of fit for normality.     

Multiple Comparison Procedures: The Practical Solution

A practicing statistician looks at the multiple comparison controversy and related issues through the eyes of the users. The concept of consistency is introduced and discussed in relation to five of the more common multiple comparison procedures. All of the procedures are found to be inconsistent except the simplest procedure, the unrestricted least significant difference (LSD) procedure (or multiple t test). For this and other reasons the unrestricted LSD procedure is recommended for general use, with the proviso that it should be viewed as a hypothesis generator rather than as a method for simultaneous hypothesis generation and testing. The implications for Scheffé's test for general contrasts are also discussed, and a new recommendation is made.
