资金流量表是国民经济核算体系中的重要组成部分。然而,由于在编制过程中需要采集大量的数据,通常情况下,很多国家的资金流量表都会有较长时间的滞后。在编制实物资金流量表的延长表时,已有方法通常是基于基期与预测期交易收支结构保持不变的假定条件。然而,经济结构发生显著变化时,该类方法就会失效。基于上述问题,研究弱化模型的假设条件,并提出了新的实物资金流量表预测方法( 简称 FPTF方法)。根据表中元素必须满足的约束条件,该方法通过建立数学模型解除约束,其次基于历史数据的动态趋势,采用适当的时间序列分析方法来预测目标年份的实物资金流量表。通过仿真分析,验证了所提方法的有效性和稳定性。此外,基于中国1992年~2014 年的实物资金流量表数据进行实例分析,取得了满意的分析结果。  相似文献

马克思的劳动价值论和按生产要素分配   总被引:1,自引:0,他引:1  
生产要素所有权决定劳动产品的分配。不同社会制度下劳动产品的分配不同根源于生产资料所有制的不同。市场经济条件下生产要素获取收益的方式主要有三种:把生产要素当作商品、把生产要素当作资本商品,把生产要素当作资本。无论何种方式参与分配的依据都是生产要素的所有权,而非劳动价值论:劳动价值论不是生产要素参与分配的依据,但在市场经济中两者有着内在的联系。  相似文献

梦醒寻梦——张岱及其小品文   总被引:1,自引:0,他引:1  
张岱是晚明小品文的集大成者。张岱的出身遭际和社交氛围,造就了他博雅风流、愤世谐谑的名士风度;张岱小品的内容十分丰富,殆同一幅全景式的明末风俗画;所表达的思想感情十分复杂,而最值得注意的是郁积其中的黍离情结;审美品味求真求廉、求空灵自然;风格洒脱谐谑、恣肆;境界既世俗又博雅,既真切又空灵。  相似文献

The socio-ecological challenges facing communities in the 21st century are building towards a critical conjuncture of history, culture, power, and profound inequity. Scholars working in the service of social transformation and improving the wellbeing of communities are calling for creative, deliberate, and consequential interventions. Tharp & O’Donnell (this issue) call for increased engagement between Cultural-Community Psychology and Cultural-Historical Activity Theory to lead this kind of call. Drawing from our experiences in community based design research, we argue for cultivating axiological innovations in research and interventions. We explore three examples including: critical historicity, inter-generational learning, and strategic transformations of institutional relations.  相似文献

This paper seeks to understand key dimensions of reflection in experience-based workplace learning for research being collaboratively undertaken by scholars in Dutch and US research institutions. We systematically explore and compare Tara Fenwick’s analysis of five perspectives on cognition to distinguish among constructivist, psychoanalytic, situative, critical-cultural, and enactivist perspectives on reflection. Our aim is to examine how to conceptualize reflection so that one or more perspectives can complement our understanding of learning through experience at work. We position reflection not only from a practical but also from a theoretical perspective that moves beyond the individual focus of the constructivist perspective. Fenwick’s five perspectives are described in terms of whether and how reflection is utilized, key activities in the process of reflection, relative focus on the individual and/or the context, triggers for reflection, role of power and positionality, role of emotions, and reflection outcomes. We conclude that adding other lenses to the dominant constructivist perspective helps expand our understanding of reflection as well as identify and attend to other tools, people, and factors in the work situation that influence reflection processes and learning outcomes. The paper closes with a discussion of promising new approaches that have emerged since Fenwick’s analysis.  相似文献

For a given graph and an integer t, the MinMax 2-Clustering problem asks if there exists a modification of a given graph into two maximal disjoint cliques by inserting or deleting edges such that the number of the editing edges incident to each vertex is at most t. It has been shown that the problem can be solved in polynomial time for \(t<n/4\), where n is the number of vertices. In this paper, we design parameterized algorithms for different ranges of t. Let \(k=t-n/4\). We show that the problem is polynomial-time solvable when roughly \(k<\sqrt{n/32}\). When \(k\in o(n)\), we design a randomized and a deterministic algorithm with sub-exponential time parameterized complexity, i.e., the problem is in SUBEPT. We also show that the problem can be solved in \(O({2}^{n/r}\cdot n^2)\) time for \(k<n/12\) and in \(O(n^2\cdot 2^{3n/4+k})\) time for \(n/12\le k< n/4\), where \(r=2+\lfloor (n/4-3k-2)/(2k+1) \rfloor \ge 2\).  相似文献

The composite quantile regression (CQR) has been developed for the robust and efficient estimation of regression coefficients in a liner regression model. By employing the idea of the CQR, we propose a new regression method, called composite kernel quantile regression (CKQR), which uses the sum of multiple check functions as a loss in reproducing kernel Hilbert spaces for the robust estimation of a nonlinear regression function. The numerical results demonstrate the usefulness of the proposed CKQR in estimating both conditional nonlinear mean and quantile functions.  相似文献
