Rethinking Samir Amin’s legacy and the case for a political organization of the global justice movement

ABSTRACT

A case is made here for the desirability and viability of the late Samir Amin’s call for a new International. However, the project to forge a political organization of the global justice movement must in the first instance draw lessons from the limitations of the recent network structure of new social movements, notably the World Social Forum, and rectify the failures of the old internationals of left-wing cadres. The actualization of such a radical idea also needs to observe the realpolitik of class formation and class struggle under conditions of the imperialistic globalization of capitalism today. Envisioned as a plural and participatory learning organization, the new International’s progression should be evolutionary and its strategic engagements have to balance the imperatives of political realism with the ideals of democratic values.     

Meta-analysis using multilevel models with an application to the study of class size effects

Meta-analysis is formulated as a special case of a multilevel (hierarchical data) model in which the highest level is that of the study and the lowest level that of an observation on an individual respondent. Studies can be combined within a single model where the responses occur at different levels of the data hierarchy and efficient estimates are obtained. An example is given from studies of class sizes and achievement in schools, where study data are available at the aggregate level in terms of overall mean values for classes of different sizes, and also at the student level.     

Class Size and Educational Policy: Who Benefits from Smaller Classes?

ABSTRACT

The impact of class size on student achievement remains an open question despite hundreds of empirical studies and the perception among parents, teachers, and policymakers that larger classes are a significant detriment to student development. This study sheds new light on this ambiguity by utilizing nonparametric tests for stochastic dominance to analyze unconditional and conditional test score distributions across students facing different class sizes. Analyzing the conditional distributions of test scores (purged of observables using class-size specific returns), we find that there is little causal effect of marginal reductions in class size on test scores within the range of 20 or more students. However, reductions in class size from above 20 students to below 20 students, as well as marginal reductions in classes with fewer than 20 students, increase test scores for students below the median, but decrease test scores above the median. This nonuniform impact of class size suggests that compensatory school policies, whereby lower-performing students are placed in smaller classes and higher-performing students are placed in larger classes, improves the academic achievement of not just the lower-performing students but also the higher-performing students.     

毛泽东分界知识分子标准的自我矛盾解析

政治态度与世界观是毛泽东分界知识分子的主要标准。完全、准确、客观的厘清毛泽东界定知识分子革命性质的政治标准与其阶级性质的世界观标准的内涵及二者之间的矛盾,不仅有助于透视毛泽东时代中国共产党对待知识分子的一系列政策及活动,深刻把握当代中国共产党的知识分子政策的理论根源,而且也对于当下的中国如何在意识形态领域坚持马克思主义的主导地位具有重要启示意义。     

关于提高本科生专业外语学习效率的研究

在简要介绍现阶段专业外语课程基本情况的基础上,以农业水土工程专业为例,对该课程在教材选择、课时和教学方法等方面存在的主要问题进行了研究。同时结合实际教学,提出了四点改进方法,即选择专业对口、系统性和完整性较好且难易程度适中的教材;课时量应适当增多;养成良好学风及端正学习态度和灵活的教学方法等,以此顺利展开该课程的深入学习。     

冲突经济学视域下的阶级斗争与社会变革

马克思经济学理论中,生产力与生产关系的矛盾是社会变革的原因。利用冲突经济学中的CFS模型,采用阶级的分析方法,对上述论断提供一种证明。不同阶级掌握的生产力水平决定了本阶级资本存量的积累速度,资本存量决定了斗争的有效性。根据CFS,阶级斗争的过程大体可以分为四个阶段,各阶级根据斗争有效性采取不同的策略,各阶段随之呈现激烈与缓和斗争状态。掌握先进生产力的阶级取得胜利具有必然性。研究显示了阶级斗争也是有效率的资源配置方式。     

IRUSRT: A Novel Imbalanced Learning Technique by Combining Inverse Random Under Sampling and Random Tree

In this article, a novel technique IRUSRT (inverse random under sampling and random tree) by combining inverse random under sampling and random tree is proposed to implement imbalanced learning. The main idea is to severely under sample the majority class thus creating multiple distinct training sets. With each training set, a random tree is trained to separate the minority class from the majority class. By combining these random trees through fusion, a composite classifier is constructed. The experimental analysis on 23 real-world datasets assessed over area under the ROC curve (AUC), F-measure, and G-mean indicates that IRUSRT performs significantly better when compared with many existing class imbalance learning methods.     

略论和谐的马克思主义——阶级斗争理论与构建社会主义和谐社会

阶级斗争理论是马克思主义的重要组成部分。但是，理论发展与应用应该与具体社会发展阶段相一致。社会主义制度确立后，阶级矛盾不是中国社会的主要矛盾。在当前，更应该强调社会和谐发展理论。也只有把社会主义作为一种运动，从社会发展的实际出发，不断推进社会主义理论创新，才能真正实现马克思主义理论与实践的统一，推进社会主义事业不断发展。     

介乎士大夫与平民之间的文学形态——南宋中后期游士阶层的诗歌创作

游士自视为士人阶级并努力向士大夫靠近，但其社会身份却更接近平民。游士议政诗歌具有士大夫般的忧时忧国情怀，却因为过于激烈直白而被质疑为卖直钓名、粗豪亢厉之作；游士诗歌力求风雅，却被视作矫语高蹈的伪风雅；游士诗歌情调语调通俗，却与平民赏爱的话本、杂剧、南戏尚有一点距离，无法被庶民百姓广泛接受。游士阶层介乎士大夫与平民之间的中间游移性质，使其诗歌成为传统文体大幅度变革的载体，是南宋文化转型以及文学转型时期一个士庶交接、雅俗杂糅的文学形态，也是俗文学冲击下雅文体之俗化达到了临界点的标本。
