构建大学新型体育教学模式多维因子辩证分析——以黑龙江省为例

在21世纪国际社会飞速发展的形势下,体育教学在以人为本的前提下已经是一个多向、动态的过程。因此构建大学新型体育教学模式要不断研究至关重要的多维因子,使体育教学在思想体系层面上充分体现辩证统一,促进从生理改造向生理、心理、适应能力、创造能力、生存能力并重的模式发展。     

Expectation-driven fluctuations and welfare loss under free trade in two-country models

This paper investigates the interlinkage in the business cycles based on expectation-driven fluctuations of large-country economies in a free-trade equilibrium. We consider a two-country, two-good, two-factor general equilibrium model with sector-specific externalities. We show that some country's expectation-driven fluctuations can spread throughout the world once trade opens even if the other country has determinacy under autarky. We thus prove that under free trade, globalization and market integration can have destabilizing effects on a country's competitive equilibrium. Finally, we characterize a configuration in which opening to international trade improves the stationary welfare at the world level but deteriorates the stationary welfare of the country that imports investment goods and exports consumption goods. We conclude that in opposition to the standard belief, international trade might not be beneficial to all trading partners in the long run.

开放经济条件下我国货币需求研究

文章引入股票流通市值、汇率等变量对开放经济条件下我国货币需求函数进行全面研究。协整和误差修正模型结果表明：汇率是除社会消费品零售总额外影响我国长短期货币需求稳定的最重要的变量,并且对我国货币需求的影响很大;股票市场发展对我国长期和短期货币需求的影响很小。这一发现可为我国当前反通货膨胀的货币政策的制订提供重要的参考。为控制货币供应量,我们应该重点关注汇率波动。     

贸易顺差、冲销操作和货币政策效应的非对称性

文章利用＂G—R＂模型和结构向量自回归模型,实证分析我国货币政策的独立性和非对称性,通过我国汇改前后的比较得出,汇改之前货币政策独立性小于汇改之后,但汇改后,为保持汇率稳定而进行的冲销操作在很大程度上削弱了我国货币政策的独立性。通过江苏、山东和四川三省的实证分析得出,货币政策效应存在明显的区域差异。     

基于过程模型和资源视角的上海制造业企业信息化影响因素实证研究

文章基于过程模型和资源视角,构建了信息技术价值创造的研究模型,通过对上海398家制造业企业的调查．采用结构方程模型方法对调查数据进行统计分析,揭示了上海制造业企业信息化的价值创造过程,验证了从IT投资到产生价值的路径,证实了政府推动政策、IT基础设施、IT管理等因素对制造业企业信息化的影响。     

腐败循环博弈模型的构建

腐败循环是一种腐败问题持续发生的现象,为什么这一现象难以得以根除？文章利用官员和承包商之间一个简单的博弈模型来对此问题进行探析,找出阻断腐败循环的方法。     

贝叶斯方法在二维目标定位中的应用

本文对如何运用贝叶斯方法,以一维方式采集资料,进行二维目标定位作了一些探讨。实验中,运用光电计测定出发射和接收红外二极管的模式,通过分析建立起物体的二维模型方程,然后运用贝叶斯方法,估计出物体在坐标中的水平位置和垂直距离。进而验证了这种基于贝叶斯方法的二维物体定位算法。这为以后研制具有较强实用性的地雷探测仪或者是其它的不方便进入目标区域情况下的应用提供了方法上的依据。     

The role of corrosive internalisation and denial of responsibility in stabilising inequality in South Africa

ABSTRACT

This paper examines how capabilities inequality is stabilised through its consequences on those at both ends of the distribution. It outlines the development of the balance model, which is argued to help highlight these consequences. Specifically, how adverse environments associated with lack of access to resources and poor treatment can lead to internal consequences which further corrode capabilities. At the same time, denial of this corrosion or its importance is critical for those who benefit from the inequality. To avoid moral constraints being triggered it is important, necessary even, for them to see those who suffer as outside of their moral universe, or their suffering to be in no way associated with their advantage. Corrosion and denial work to stabilise the system. For those in the middle of the distribution, they may work to do so in combination. Appreciating these internalised consequences is key to addressing inequality in South Africa.     

Marx,Sraffa, and Surplus: Observations Prompted by Garegnani (2018)

ABSTRACT

In a posthumously published article, Pierangelo Garegnani (2018. ‘On the Labour Theory of Value in Marx and in the Marxist Tradition.’) depicts Marx’s project in Capital as that of ‘developing systematically the theory of Ricardo and [the] implications of social conflict’ implied by Ricardo’s ‘surplus approach to value and distribution’. This paper argues to the contrary that Marx’s theory of surplus value and exploitation differs from (neo-)Ricardian surplus theory in fundamental ways, and modifies Garegnani’s simple Sraffian model to illustrate the distinctive implications of Marx’s theory.
