国有经济在国民经济中的核心地位

国有经济在国民经济中的核心地位是毋庸置疑的 ,关键是国有经济在国民经济中所占比例应该存在一个平衡的尺度点 ,这个尺度点与外在的国际环境和内在的社会结构密切相关。文章分析了国有经济及其变形形态 ,并描述了其运行规律。文章强调 ,社会人的公私二像性特征是深刻理解国民经济体系中国有经济未来发展趋势的理论基石。     

Some remarks on the duality of continuous time markov chains

A simple proof of Siegmund's result on the relation between dual q-matrices and dual transition functions for Markov chains is given. A byproduct is a uniqueness result for minimal solutions of stochastically monotone q-matrices.

欧几里得空间建立对偶原理的一种方法

本文旨在根据欧几里得空间的特征,探求在欧几里得空间建立对偶原理的一种方法.并利用这种方法说明初等几何中仅与度量性质有关本身并无联系的两种命题可以对偶地联系起来.     

中国新农村社区空间建设策略研究

通过对中国传统农村进行的调查,我们发现典型的空间建设模式展示出原型与标志型,它们之间存在因果关系,而在城镇化和现在化影响下,空间建设模式正在逐渐消失,部分新型社区正在高速、大规模的进行整合。这些导致了地理性建设系统和生态环境的破坏。在原型理论出发,二元性特征应该与空间建设相结合,来引导传统农村空间建设模式的传播和应用,寻找新型空间发展路径。这个路径要以可持续性、可选择性和转变为基础。     

Generalized anticipated backward stochastic differential equations driven by Brownian motion and continuous increasing process*

This article mainly considers a new class of anticipated BSDEs driven by Brownian motion and continuous increasing process, which are called generalized anticipated backward stochastic differential equations(GABSDEs). We first give the form of GABSDEs. Then, existence and uniqueness result for GABSDEs is established as well as a comparison theorem is obtained under the certain assumptions. At last, we give an application about the duality between SDDEs and GABSDEs.     

Giddens’ structuration theory and its implications for management accounting research

The purpose of this essay is to briefly review the pillars and the rationale of Giddens’ theory of structuration, and offer a snapshot of the impact of these ideas on research in management accounting. Conceptualised as a way of making sense of social life, structuration theory represents a sensitizing device for researchers, which has be drawn upon “in a selective way in thinking about research questions or interpreting findings” (Giddens, Modernity and self-identity: Self and society in the late modern age, 1991). In the following pages the duality of structure, the modalities of structuration, the concept of double positioning, the theory of the subject as well as concepts such as ontological security, routines or trust will be reviewed as essential elements of a vocabulary originally framed within Giddens’ The constitution of society (1984). The essay ends sketching the work of Macintosh and Scapens (Management accounting and control systems—an organisational and behavioural approach, 1990), who broke new ground to interpret management accounting systems in light of structuration theory terms and concepts, as well as some of the more recent works in accounting that have built on Giddens’ latest ideas on the The Consequences of Modernity (1990).

Dynamic network analysis of contact diaries

Analyzing two-mode networks linking actors to events they attend may help to uncover the structure and evolution of social networks. This classic social network insight is particularly valuable in the analysis of data extracted from contact diaries where contact events produce — and at the same time are the product of relations among participants. Contact events may comprise any number of actors meeting at a specific point in time. In this paper we recall the correspondence between two-mode actor–event networks and hypergraphs, and propose relational hyperevent models (RHEM) as a general modeling framework for networks of time-stamped multi-actor events in which the diarist (“ego”) simultaneously meets several of her alters. RHEM can estimate event intensities associated with each possible subset of actors that may jointly participate in events, and test network effects that may be of theoretical or empirical interest. Examples of such effects include preferential attachment, prior shared activity (familiarity), closure, and covariate effects explaining the propensity of actors to co-attend events. Statistical tests of these effects can uncover processes that govern the formation and evolution of informal groups among the diarist’s alters. We illustrate the empirical value of RHEM using data comprising almost 2000 meeting events of former British Prime Minister Margaret Thatcher with her cabinet ministers, transcribed from contact diaries covering her first term in office (1979–1983).     

国民党抗战时期政治体制述评

抗日战争时期,国民党在原有的以党治国和五院制政府的训政体制上,形成了以蒋介石为领袖,以国防最高委员会为决策和执行机关的党政军一体化战时体制。同时还设立了各级民意机关。这一战时政治体制,具有集权与民主二重性。但其主流和发展趋向是不断强化国民党的一党专政和蒋介石的个人独裁。由此,也使国民党政权走向腐败的深渊。     

Benefit-of-the-doubt aggregation and the diet problem

In this note we show that the diet problem and the benefit-of-the-doubt (BoD) aggregation are linear programming duals. That is, the primal (dual) formulation of the diet problem is equivalent to the dual (primal) formulation of the BoD model as long as food prices are set equal to one. In addition, we show that the diet problem and the inverted BoD model are linear programming equivalent as long as the nutritional requirements are set equal to one.
