INDIFFERENCE PRICE WITH GENERAL SEMIMARTINGALES

Using duality methods, we prove several key properties of the indifference price π for contingent claims. The underlying market model is very general and the mathematical formulation is based on a duality naturally induced by the problem. In particular, the indifference price π turns out to be a convex risk measure on the Orlicz space induced by the utility function.

小户型设计中的扩展艺术

由于房价高企,城市人口增多,小户型成为年轻人的热门选择。户型虽小但是生活却不会因此而缩小,如何在有限的空间中创造出最大的使用功能,是目前很受关注的一个问题。因为小户型的空间划分和布局受到户型和面积的限制,装修时往往导致房屋空间功能不全,或者房屋的整体协调性美观程度降低。因此在装修前,需要按照自己的需求对空间进行重新划分,使其在更合理化、人性化,同时整体协调,不杂乱。只要有合理的布局,小户型也可以拥有舒适的生活空间。     

Defensible Space on the Move: Revisiting the Urban Geography of Alice Coleman

This article traces the movement of the concept of ‘defensible space’ from New York City in the 1970s, where it was developed by the Canadian architect/planner Oscar Newman, to London in the 1980s and into design interventions in British public housing in the 1990s, through British geographer Alice Coleman, who acted as an especially powerful transfer agent. In focusing on this urban design ‘concept’ on the move we contribute to existing scholarship on policy mobility and city building in a number of ways. First, we explore an instance of the movement/mobility of a planning concept in a historical period (the recent past) largely overlooked to date. Secondly, we demonstrate that this movement was the result of a disaggregated series of expert knowledge transfers and localized translations of pre‐policy expert knowledge, generated through university‐based research work and networks. We theorize this instance of urban planning mobility by way of the interlinked insights offered by the sociology of science and policy‐mobilities literatures. As this is an instance of university research shaping public policy it also offers an opportunity to reflect upon the meaning of ‘evidence‐based policy’ and the impact agenda in contemporary higher education.     

Tourism spatial reconstruction of Chengde City under the influence of Holiday Tourism Circle of Beijing

Holiday Tourism Circle of Beijing （HTCB） is one of the nine key regions of Chinese tourism industry in the period of the 11^th Five-Year Project. According to Tourist Marginal Utility Theory, Time-Distance Method is used to define HTCB in this paper. Chengde City, famous for its cultural tourism, is regard as one of the regions in Holiday Tourism Circle of Beijing. And this geographical advantage, in the context of the boom of tourism in China, is featured by the changes of tourist product structure and development model. In this paper, the influence upon Chengde tourism spatial structure has been discussed from tourist market, location and transportation. Chengde tourism spatial structure has been rebuilt with particular references to the factors of tourism destination district, tourist area, nodes, routes, and origin markets. In this paper, Chengde will develop tourism industry with the central heritage area as the center and northern forest and pasture area and southern mountain and lake area as the two wings.
