再论马克思的分配理论及其现实意义——重读《哥达纲领批判》

马克思的《哥达纲领批判》一文充分阐述了关于分配的一般理论和特殊分配原则,即共产主义第一阶段的按劳分配原则和共产主义高级阶段的按需分配原则。马克思的分配理论不仅是社会主义国家分配的理论渊源．而且是中国当下收入分配制度改革的重要指导思想。

APPLYING A GENETIC ALGORITHM TO INTERNATIONAL DIVERSIFICATION OF EQUITY PORTFOLIOS: A SOUTH AFRICAN INVESTOR PERSPECTIVE

This paper uses the genetic algorithm (GA) approach to generate a portfolio optimisation scenario of a South African investor who seeks to maximise return from investing in S&P500, FTSE100, NASDAQ, DOWJONES, CAC40 and the DAX from January 1, 2005, to January 31, 2008, but facing exchange rate risk. The GA searches for the optimal solution in the entire set of financial constraints without looking for partial derivatives of the utility function. Whereas most financial problems require a non‐linear and time‐varying model, the GA, with its survival principle of offspring chromosomes, is better suited to this type of problem than local optimisation methods. The performance of the GA is compared with two non‐linear models, namely the quadratic mean‐variance (QMV), which maximises the portfolio mean‐variance, and the quadratic variance minimisation (QVM), which minimises the portfolio variance. The results show that neither the QMV nor the QVM takes into account the domestic investors' risk attitude towards investing in foreign equities and therefore does not provide any international diversification benefits. In addition, the bootstrapping scenario of 10,000 simulations reveals that neither the QMV nor the QVM outperforms the GA in terms of Sharpe ratio and flexibility in dealing with investors' risk attitude towards investing in foreign equities denominated in foreign currencies.

上海合作组织命运共同体:一项研究议题

构建上海合作组织命运共同体是中国政府提出的关于促进上海合作组织长远发展的重大倡议。由于上海合作组织命运共同体理念的提出时日尚短,学术界关于该理念的研究尚未全面启动。要使上海合作组织命运共同体理念成为一个有效的研究议题,不仅需要明晰上海合作组织命运共同体的具体内涵,而且需要将其纳入国际共同体、国际组织和大国外交等议题的研究,提炼出一些具有普遍性的理论命题。就攸关上海合作组织命运共同体构建的重大问题而言,至少需要回答上海合作组织命运共同体提出的理论与实践意义、上海合作组织命运共同体构建应遵循的基本路径、上海合作组织命运共同体构建的基础和条件、上海合作组织命运共同体构建面临的挑战与障碍、学术界能为上海合作组织命运共同体构建提供的对策建议等重大问题。在此过程中,学术界还需将其与周边命运共同体、人类命运共同体等家族相似性的概念纳入同一研究视域,以澄清上海合作组织命运共同体的内涵与外延,辨识上海合作组织命运共同体演变的动力与机制,并从理论层面提炼上海合作组织发展经验的特殊性与普遍性。

原型范畴理论视角下的英语时态认知解读

原型范畴理论作为认知语言学概念的基础近年来逐渐得到了语言学家的重视。原型范畴理论可以用于英语教学并对英语时态具有一定的解释力,从而为英语时态教学开辟新视角。本文以一般现在时态、一般过去时态、一般将来时态为例,探索原型范畴理论在英语时态教学中的应用。希望能推动该理论在英语时态教学中的应用。     

百年炮火中的未竟之学——对民国时期国际关系研究与教学的回溯

作者凭借史料,并参考、评价和补充既有学术史研究成果,对民国时期的国际关系学进行回溯。作者首先聚焦学术著作、教材和大学课程设置,认为民国时期国际关系学形成于国际关系史学和国际法学的基础之上、并逐渐朝多元化发展的过程演进,中国的国际关系学科是在20世纪30年代形成的。其次,文章考察了20世纪30年代中国期刊发表外交论文情况,以《外交月报》与《外交评论》为考察对象,重点探讨了民国学者在外敌压境下,放眼国际形势、关注国际格局、思考中国问题,在舆论界发出学术界的声音,尝试以智识指导舆论。国际关系学在民国时期的发展始终与国家的命运相联系,在百年炮火之下,国人眼界逐步放宽,学界亦秉持务实的精神,为实现中国之自由与平等,从被动学习到主动研究,从了解世界到救亡图存,在西学与中学交汇、政治与公众之间寻求自身的平衡点。百年前的未竟之学,要求我们对整个国际关系加以深入的研究,从而建立起一个完整的国际关系学。     

“Should I stay or should I go?”—Why the future of global work may be less binary: Lessons on approaches to global crises from the experiences of expatriates during the COVID-19 pandemic

COVID-19 has significantly impacted expatriates, affecting their ability to work effectively and their personal and family lives. This study explores their experiences in different phases of the pandemic, and their perspectives on the future of international living in light of such global disruption. Involving over 600 expatriates in 48 countries, the research shows shifts in motivation and priorities as a result of the crisis and reveals how family (extended and immediate) topped expatriates' concerns. The study examines if and how support systems worked and looks at coping mechanisms, skills, traits, previous experience, and attitudes which participants found useful. A common theme was “falling between two stools”—where expatriates were ineligible for support in either their home country or in their host country. Others described being “pulled in different directions” or “torn by a dilemma” with pros and cons in either choice. The study contributes to the questions about the future of global work with results of the survey revealing changing norms for expatriation and global mobility raising the possibility of more nuanced approaches to global projects and less binary options for global professionals and their families.
