Expanding Socio-economics in Four Dimensions

Abstract

During the last decades the rapid progress in the fields of complex modelling and simulationor in the cognitive and the life sciences was not accompanied by a similar advancement of the socio-economic research tradition itself. Socio-economics as a hybrid field for the complex dynamics of modern societies across their micro-, meso- and macro-levels has still a long way to go in order to reach its full potential. The present article provides a general outline for expanding and advancing socio-economics along four different dimensions which should be able to produce a significant take-off for socio-economic theories, models, methods and mechanisms.     

基于复杂网络理论的电动汽车充电设施布局合理性研究

提出了一种基于复杂网络理论构建电动汽车充电设施网络的模型,分别构建了上海、西安、合肥和大连的电动汽车充电设施网络,并分析了其电动汽车充电设施的运营情况以及布局的合理性。通过构建理想情况下的电动汽车充电设施网络,研究电动汽车充电设施网络的发展趋势。仿真结果显示:电动汽车充电设施网络的结构对电动汽车充电设施的利用率和稳定性有显著影响——该研究结果在实际网络中得到了验证。     

Synchronization and diversity in business cycles: a network analysis of the European Union

In this article, we use a correlation matrix and its internal networks to analyse business cycle synchronization across Europe since 2000. This methodology allows us to summarize individual country interactions and co-movements while also capturing the existing heterogeneity of connectivity within the European economic system. Our results indicate that synchronization of the euro zone countries remained stable from 1999 until the current financial crisis, after which co-movements increased sharply and synchronization rose to the highest in the time sample. By endogenously identifying clusters of countries with close connections in their business cycle, we also refute the commonly accepted notion of identifiable core and peripheral euro zone countries.     

“Social Freedom” in the Twenty-First Century: Rereading Polanyi

Karl Polanyi’s analysis of the genesis, crises, and institutional transformations of contemporary society is grounded on a theory of the basic features and dynamics of capitalism as a peculiar form of society. This article intends to develop this thesis on the basis of a reading of Polanyi’s The Great Transformation, with references to Polanyi’s preceding and later research. Polanyi’s theoretical and methodological achievements suggest a wide comparative outlook and offer a critique of economics, in addition to being deeply connected with his political philosophy. Polanyi’s approach seems to be nearer to the original institutional thought — from Karl Marx to Thorstein Veblen, from Max Weber to Adolf Löwe and Karl William Kapp — than to current neo-institutional tendencies in economics, sociology, and historiography. The hard problems society presently faces suggest the need to adhere to Polanyi’s radical point of view — that is, to a radical approach to Polanyi’s thought.     

复杂适应系统理论在股市模拟中的应用

资本市场是由金融产品提供者(如上市公司)、交易所和投资者组成的系统。随着经济的不断发展,股票市场已成为我国资本市场中最活跃、发展最快速的市场,因此它也成为众多专家学者研究的焦点。传统的金融学理论对于股票市场中许多普遍存在的特征性事实,如尖峰胖尾、波动聚集等现象难以解释。与此同时,传统的线性数学分析方法也陷入了前所未有困境。在环境的要求下,复杂适应系统理论在金融学中的应用所具备的优势逐渐显露出来。     

应用于复杂电磁环境下的一种新型船艇导航系统

复杂的电磁环境是未来信息化战场最突出的特征,这样的环境将会干扰现有依靠无 线电波进行工作的导航系统。为有效解决船艇在复杂电磁环境下的导航问题,提出了一种以 陆标定位为基础的新型船艇导航系统。系统通过高清度摄像机和磁航向传感器获取观测物标 数据,经过计算机解算,将位置信息显示到电子海图上。海上试验情况表明,与传统的陆标 定位相比,本系统在定位时间、定位精度等方面具有明显的优越性,完全满足军事航海的要 求,具有良好的军事效益。     

The density of the time to ruin for a Sparre Andersen process with Erlang arrivals and exponential claims

We derive expressions for the density of the time to ruin given that ruin occurs in a Sparre Andersen model in which individual claim amounts are exponentially distributed and inter-arrival times are distributed as Erlang(n,?β). We provide numerical illustrations of finite time ruin probabilities, as well as illustrating features of the density functions.     

The Political Economy of Addressing the Climate Crisis in the Earth System: Undermining Perverse Resilience

The Earth system is a complex adaptive system, characterised by non-linear change and with significant capacity for surprise. In times of systemic crisis, such as dangerous anthropogenic climate change, perverse resilience (for example the structural power of fossil fuel interests in the global economy) can threaten overall Earth system stability. Critical political economic analysis recognises climate change as a threat with significant political economic characteristics and implications. However, key dimensions of climate change as a globally coherent phenomenon, including the important implications of Earth system dynamism and non-linear change, can remain unrecognised, mischaracterised or underestimated. In contrast, resilience approaches describe social-ecological systems but neglect the significance of norms and power relations in human societies. This article builds theory by linking key concepts – hegemony and resilience – from neo-Gramscian political economic analysis and resilience approaches to social-ecological systems. Our objective is to generate a new conceptual framework to improve understanding of the role of politics in social-ecological systems. We use climate change and its mitigation to demonstrate the new framework's potential.
