Karyological analysis of the sea cicada Blepharipoda liberate Shen from the Rizhao intertidal zone, China

Blepharipoda liberate Shen is a commercially valuable seafood species that has important ecological signi?cance in Shandong Province, China. Although B. liberate is crustacean, its external characteristics are not entirely those of shrimps or crabs. The question of whether B. liberate is a shrimp or a crab has been debated in recent years. We studied the karyotype of B. liberate by light microscopy using air-drying and spreading methods. We obtained mitotic chromosomal plates from B. liberate larvae, and from adult B. liberate females subsequent to egg-laying. The results revealed that B. liberate has 53 pairs of chromosomes(i.e., n =53 and 2 n =106), a characteristic shared with four species of crab. The karyogram of B. liberate consists of 25 metacentric, 14 submetacentric, 11 subtelocentric and 3 telocentric pairs. We did not ?nd any heteromorphosis sex chromosomes. Tissue from larvae, gills and ovaries can be used for chromosomal investigations, and we found similar lampbrush chromosomes in ovary cells. Comparatively speaking, larvae tissue is more practical, and ovary tissue is more suitable for the preparation of lampbrush chromosomes. B. liberate is more closely related to crabs than to shrimps, based on the numbers of chromosomes. The B. liberate karyotype reported here provides a basis for further comparative cytogenetic studies of species populations.

Liberate进入中国广电

面对嘉里中心小会议室玻璃窗外北京的高楼大厦,Mr.MitchellKertzman(米切尔·柯兹曼),这位来自硅谷的传奇人物不禁感叹:中国的变化是如此巨大,相比10年,5年,甚至2年前,都有太大的不同.特别是中国政府高层,广电总局领导所表现出来的先进管理运营思想及模式已在接近西方,这一改变更给他带来深刻感受.

“liberal arts”的源与流——古今之变中的审视

“古今之变”是审视liberal arts流变的中心线索。古典liberal arts是具有内在统一性并指向完满品格的整全性知识体系。欧洲三次文艺复兴对liberal arts的再造展现了其历史流变中的不变逻辑,即为特定时代的受教育者提供共同价值。德国古典大学赋予了liberal arts在古典意义上的完美形态,而新人文主义的自我塑造观念孕育了博雅教育的现代转向。科学革命终结了古典学术的内在统一性与道德理想,瓦解了古典liberal arts。美国现代大学则借助古典资源,经由三次改革浪潮重建了liberal arts。然而,古典教育凝聚文明精华的共同价值、塑造意义与学术整合力量,同现代科学的智识自由、价值分殊与学科分化特性相冲突,这是古今之变为现代大学再造liberal arts所深植的困境,liberal arts只能在钟摆的两端之间不断权衡。

英文“liberal arts”真的等于“文科”或“人文学科”吗?——兼论翻译中的词汇空缺现象

伴随古希腊哲学思想兴起的liberal arts,体现了古希腊人对“普遍理解”的追求,经古罗马、文艺复兴及近世以降之经年累月发展,此概念之内在含义已然超越单纯之“文科”或“人文学科”的范畴,涵盖更广泛的学科领域。Liberal arts旨在培养学生广泛的知识和技能,包括批判性思维、沟通技巧、文化理解和全球意识等,从而使他们成为具有丰富知识和广泛兴趣的人。纵观liberal arts的发展,不宜将其简单翻译为“文科”或“人文学科”,可根据不同语境将其译为“通识教育”“博雅教育”,乃至“文理教育”。

The effect of overseas investors on local market efficiency:evidence from the Shanghai/Shenzhen–Hong Kong Stock Connect

Using a recent stock market liberalization reform policy in China—the Stock Connect—as a quasi-natural experiment,this study examines the effect of stock market liberalization on market efficiency.Employing a dataset of 17,086 Chinese listed firms covering 2009 to 2018,we find that stock market liberalization improves the market efficiency of the Chinese mainland stock market.We further explore the potential channels through which the Stock Connect can enhance the efficiency of the A-share(A-shares refer to shares issued by Chinese companies incorporated in China's Mainland,traded in the Shanghai Stock Exchange and the Shenzhen Stock Exchange.They are denominated in Chinese RMB(the local currency).A-shares were restricted to local Chinese investors before 2003,are open to foreign investors via the Qualified Foreign Institutional Investor,RMB Qualified Foreign Institutional Investor,or the Stock Connect programs.)market.The findings show that liberalizing capital markets could benefit local market efficiency by increasing stock price informational efficiency and improving corporate governance quality.The additional analysis shows that stock market liberalization has a significant and positive impact on local market efficiency,enhancing firm value and reducing stock crash risk.We conduct various robustness checks to corroborate our findings.This study provides important policy implications for emerging countries liberalizing capital markets for foreign investors.

保守主义强化:俄罗斯对外政策态势

The political essence of Russian conservatism is to respect the historical tradition and take a development path aligned with Russia's national conditions.Since Putin came to power,Russian conservatism has developed into the mainstream official ideology,becoming the core concept of Russia's current domestic and foreign policies.Russian conservatism is not only the guiding principle of Russia's national foreign policy,but it is also the moral banner of Russia's diplomacy,which reflects its foreign cognition and value system.Under the guidance of conservatism,Russia's foreign policy has distinct offensive features,and Russia has intensified its efforts to counter the liberal international order dominated by the West.After the escalation of the Ukraine crisis,the status of conservatism as Russia's mainstream ideology has been further consolidated,exerting a comprehensive influence on foreign policy.Against the background of extreme sanctions and isolation from the United States and the West,Russia has turned its diplomatic attention to non-Western countries,hoping to build a new international order.

Teaching Reform and Practice of Finance under the Background of New Liberal Arts

Under the background of new liberal arts,the problems existing in the teaching process of Finance were re-examined.For instance,the setting of teaching objectives does not meet the requirements of construction of new liberal arts,and teaching content emphasizes theory;teaching method is single,and teaching assessment is not reasonable.It is proposed that the curriculum reform should be carried out from five dimensions:teaching objective,teaching content,teaching method,practice system and teaching evaluation,so as to meet the requirements of construction of new liberal arts.

The Pathologies of Modernity:Liberalism,Nihilism,Conservatism,Postmodernism,Intersectionality/Identity Politics,and Secular Humanism

In this article,Mocombe highlights what he calls the pathological-pathogenic purposive-rationalities(liberalism,nihilism,conservatism,postmodernism,intersectionality/identity politics,and secular humanism)that emerge out of modernity as constituted by the West under American hegemony.In the place of these pathological-pathogenic responses to the vagaries of modernity,Mocombe calls for an antihumanism,associated with what he calls libertarian communism,as a panacea to the aforementioned malaises.

National Revival and Workers Liberation in the Polish Issue-The Differences Between Marx and Engels and Proudhonists During the First International

In the international communist movement in the 19th century,the national uprising in Europe and the workers’movement were intertwined,forming a complex historical background.The Polish National Uprising in 1863 became a historical opportunity for the establishment of the First International.Although the unity of the British workers and the French workers was the realistic basis of the First International,the French workers showed a vague attitude different from the British workers on the Polish issue.In the first Congress of the First International,the French workers who almost are Proudhonists rejected the issue of supporting the Polish nation against the Tsar Russian oppression.Pierre-Joseph Proudhon did not link the Polish issue with the workers’movement,while he insisted that social and economic issues should not be confused with political reconstruction,and artificially separated national revival from workers’liberation.In order to promote and assist the establishment of the First International,Marx made certain consideration and concessions on national issues in the formulation of its declaration and constitution.Then Engels,commissioned by Marx,made some specific interpretations that they based on the difference between nation and nationality,and adhere it to the international national principle,both clearly shows the Marxism view of nation state,reveals the risk if international communist movement limited to the principle of nationalities,and also further reveals the importance to combine two great cause,national revival and workers liberation.

乡间与庙堂之争——从歌剧《白毛女》的文本生产看解放区文艺的一种创作路径

歌剧《白毛女》的文本生产经历了民间奇闻传说—现代革命故事—个人化的小说改写—集体创作的歌剧四个阶段。在文本生产的过程中,原先处于自在自为状态的民间口头叙述是丰富的、多样的、杂草丛生的,在进入到大规模的、有组织的国家文学生产之前,民间文学形态已经经历了一个民众/个人"去除杂草"的过程。正源于这种剔除,民间文化形态才会与官方意志达成默契、交融,进而进入延安文艺"把关人"的视野中,最终将其确立为重点建设的文艺项目进行集体创作,成为了解放区文艺的一种创作方式。

中国近代教会大学的办学理念——自由博雅教育

19世纪中期起,在中国的传教士对当时的中国教育提出了尖锐的批评,并在近代中国政府的教育体制之外办了从小学到大学的3级教育体系。教会大学办学的指导思想受到传教士所在国传统教育观念的影响。自由博雅教育(liberal education)理念是其核心,即人文的博雅全面教育观,也常被翻译为通识教育。

论杰布尔的自由原初意图主义

美国学者斯科特·杰布尔提出了新的宪法解释范式理论,即"自由的原意主义"(liberal original-ism)。他既反对脱离文本的现代自由的解释理论,也反对向后看的现代保守原意主义方法论,而主张自由的原意主义。杰布尔以历史、政治哲学和法律为分析视角,认为美国宪法的原初意图就是保护个人的自然权利。自由原意主义方法对美国宪法解释产生了深远的影响。

不同规格解放眉足蟹对活性饵料的摄食选择性研究

为探讨不同规格解放眉足蟹(Blepharipoda liberate Shen)的饵料需求,采用全人工养殖的1龄[头胸甲长(11.4±1.6)mm,体重(0.27±0.11)g]和2龄[头胸甲长(20.6±2.2)mm,体重(3.48±1.37)g]两种规格的解放眉足蟹为试验材料,开展其对卤虫(Artemia spp.)无节幼体和糠虾(Mysidacea)的72 h摄食试验。结果表明,各试验组解放眉足蟹存活率均为100%,1龄和2龄解放眉足蟹对卤虫无节幼体和糠虾均有摄食,其中1龄解放眉足蟹对卤虫无节幼体的摄食强于2龄,对糠虾的摄食弱于2龄。在解放眉足蟹人工养殖过程中,随着个体规格的增大,应及时进行饵料转换。

高水平大学建设下高校文理渗透人才培养模式探析
