浅谈高职国际商务人才观

随着经济全球化的不断深入,国际商务在国民经济中的支柱地位越来越凸现,国际商务的激烈竞争对人才的需求越来越迫切,人才问题已成为国际商务竞争的焦点。因此,作为培养国际商务人才的高职商贸学院,必须在人才培养模式方面进行全方位的改革,树立国际化的人才观。面对这种形式,本文重点探讨了高职国际商务人才应具备的基本素质。     

Contagion around the October 1987 stock market crash

This study investigates financial contagion among seven international stock markets around the October 19, 1987 crash. Building on a recent advance in vector autoregression analysis by [Swanson, N., Granger, C.W.J., 1997. Impulse response functions based on a causal approach to residual orthogonalization in vector autoregression. Journal of the American Statistical Association 92, 357–367], data-determined historical decompositions are conducted to provide a day-by-day picture of price fluctuation transmission, which is crucial to explore the financial contagion pattern characterized by rich dynamics. The results clearly show that the crash originated in the US market and that an upward movement in the Japanese market after the crash helped the recovery in the US market, which has not yet been empirically documented in the literature.     

ICT领域世界专利格局与中国标准的国际竞争

专利是决定标准竞争的母国优势中最重要的因素之一。日本、韩国、美国和欧盟在国际、国内和中国国内的专利地图中均处于强势,中国居于劣势地位。这种格局降低标准化效率,蚕食了标准竞争力。中国标准要赢得国际竞争,最紧迫的任务是瞄准标准战略展开研发活动,提高全社会的创新意识,实施专利策略     

创新与企业经营

在当今知识经济和经济全球化时代,企业原有管理制度、权责制度、组织机构已不适应现时的要求,必须采取一套新的经营管理制度和组织机构。本文针对我国一些企业,目前存在的观念落后、管理水平低、权责不明的情况,提出通过企业经营和管理的创新来提高我国企业的管理水平,构建企业改制后适应时代要求的企业经营管理新体制。     

"化学专业拔尖人才"国际化培养模式的探索

扼要介绍了北京师范大学化学学院在加强化学专业拔尖人才培养方面所开展的一系列国际化培养模式的探索,包括借鉴国际一流大学的先进培养模式(例如加入美国大学生科研训练计划),推行连贯式分层次的国际化课程学习、科学训练、综合实践项目,以及开创基于慕课平台的中外合作混合教学等。期望通过总结与反思探索出一种化学专业拔尖人才培养的有效模式。     

Stimuli-responsive fluorescent supramolecular polymer network based on a monofunctionalized leaning tower[6]arene

A fluorescent supramolecular polymer network with an excellent triple-stimuli responsive property based on metal–ligand coordination and host–guest interactions has been constructed from a terpyridine-monofunctionalized leaning tower[6]arene, a tetraphenylethylene AIEgen, and a bridging coordination ion (Zn²⁺). Addition of competitive binding agents, trifluoroacetic acid, and/or pillar[5]arene can break the metal coordination and/or host-guest inclusion complexation, and thermal heating can weaken the non-covalent interactions in the supramolecular polymer gel, all leading to the gel-to-sol transition.     

Zn-Co oxide electrodes with excellent capacitive behavior for using supercapacitor application

In the present study, super-capacitive behavior of spinel Zn-Co oxides (with different Zn⁺²/Co⁺² mol ratio) has been thoroughly investigated. The spinel of transition metal oxides with different morphologies has been synthesized with hydrothermal method on Ni foam as substrate layer. The specific capacitance of the Zn-Co oxide electrode prepared at 180 °C for 5 h with different Zn⁺²/Co⁺² mol ratios of 1:0, 2:1, 1:1, 1:2, 0:1 were investigated and measured 405, 842, 726, 1237, 705 F g^?1, respectively at 50 mV s^?1 scan rate. Zn-Co oxide with Zn⁺²/Co⁺² mol ratio of 1:2 was also synthesized at two different temperatures of 120 and 150 °C for 5 h with the specific capacitance of 1147, 917 F g^?1 at 50 mV s^?1 scan rate, respectively. Among the obtained data, the sample with Zn⁺²/Co⁺² mol ratio of 1:2 prepared at 180 °C for 5 h possessed highest specific capacitance. The cyclic life of this electrode showed 92% capacitance retention after 1000 cycle of charge-discharge. All results revealed that Zn-Co oxides had excellent supercapacitive properties due to multiple oxidation states and fast ion/electron transfer at the surface of electrode which could be offered as suitable devices for energy storage applications.

指示稳定性的反相超高效液相色谱评价原料药和制剂配方中奈必洛尔杂质的方法建立与验证(英文)

A sensitive,stability-indicating gradient reverse phase ultra performance liquid chromatographic method has been developed for the quantitative estimation of nebivolol impurities in active pharmaceutical ingredient(API)and pharmaceutical formulation.Efficient chromatographic separation was achieved on an Acquity BEH C18 column(100 mm×2.1 mm,1.7μm)with mobile phase of a gradient mixture.The flow rate of the mobile phase was 0.18 mL/min with column temperature of 30℃and detection wavelength of 281 nm.The relative response factor values of(R*)-2-(benzylamino)-1-((S*)-6-fluorochroman-2-yl)ethanol((R*S*)NBV-1),(R)-1-((R)-6-fluorochroman-2-yl)-2-((S)-2-((S)-6-fluoro-chroman-2-yl)-2-hydroxyethylamino)ethanol((RRSS)NBV-3),1-(chroman-2-yl)-2-(2-(6-fluorochroman-2-yl)-2-hydroxy ethyl amino)ethanol(monodesfluoro impurity),(S)-1-((R)-6-fluorochroman-2-yl)-2-((R)-2((S)-6-fluoro-chroman-2-yl)-2-hydroxyethylamino)ethanol hydrochloride((RSRS)NBV-3)and(R*)-1-((S*)-6-fluorochroman-2-yl)-2-((S*)-2-((S*)-6-fluoro-chroman-2-yl)-2-hydroxyethylamino)ethanol((R*S*S*S*)NBV-2)were 0.65,0.91,0.68,0.92 and 0.91 respectively.Nebivolol formulation sample was subjected to the stress conditions of acid,base,oxidative,hydrolytic,thermal,humidity and photolytic degradation.Nebivolol was found to degrade significantly under peroxide stress condition.The degradation products were well resolved from nebivolol and its impurities.The peak purity test results confirmed that the nebivolol peak was homogenous and pure in all stress samples and the mass balance was found to be more than 98%,thus proving the stability-indicating power of the method.The developed method was validated according to International Conference on Hormonization(ICH)guidelines with respect to specificity,linearity,limits of detection and quantification,accuracy,precision and robustness.
