购物中心的商户关系研究

本文基于共生理论尝试性的对购物中心内商户间的相互关系进行了研究,论文选取了竞争、寄生与互惠这三种主要关系进行分析,提出以服饰类和珠宝类商户为代表的同质商户存在着同业聚集的经济效应,这时的同业竞争相对经济效应而言属于次要地位;主力店的选择和自身所处的位置决定了寄生关系的存在与作用大小,一部分非主力店能够凭借自身的吸引力获得客流;在异质商户之间,消耗性生活便利品与超市具有高度互补性,另外百货店与衣服鞋类专卖店也具有高互补性;但是消耗性生活用品与百货店,专卖店与超市的互补性都较低。

一、引言 进入21世纪以来,城市滨水地区由于其悠久的发展历史、丰厚的文化底蕴和重要的城市区位,成为政府、公众和开发商关注的焦点,因此,滨水地带的复兴成为中国城市发展的中心议题之一.     

Labor force participation and juvenile delinquency in Taiwan: a time series analysis

This study examines the null hypothesis of Granger no-causality between labor force participation (LFP) and juvenile delinquency in Taiwan. In order to explore this issue more thoroughly, this study adopts the approach proposed by Toda and Yamamoto (1995, Journal of Econometrics, 66(1–2), 225–250). It uses official time-series data provided by the Government of Taiwan. After estimating both a four- and five-variable VAR system, one that substitutes both male and female LFP rates for the aggregate LFP rate, the primary findings of this study reveal the following: The higher the past juvenile crime rate, the lower the future aggregate and female LFP rate will be. In addition, the higher the past male LFP rate, the higher the future juvenile crime rate will be. These findings are quite robust in terms of different lag-length structures.

构建保险分支机构内控制度的对策研究

保险分支机构内控制度是保险监管和保险业风险管理的重要微观基础,当前我国保险分支机构内部控制制度建设普遍滞后于保险行业的发展,落后于保险监管和行业风险管理要求,存在一系列突出矛盾和问题。为此,一要强化分支机构改革和完善内控的内部动力,严格执行监管部门制定的制度建设指引;二要通过保险公司、监管机构、行业协会及其他相关部门给分支机构施加更强的外部压力,二者共同作用以进一步促进保险分支机构加快完善内控制度,提高保险分支机构及其所属公司管理和防范经营风险的能力,最终达到夯实保险业风险管理基础的根本目标。     

A SIMULATION ANALYSIS OF THE JAPANESE JUST-IN-TIME TECHNIQUE (WITH KANBANS) FOR A MULTILINE,MULTISTAGE PRODUCTION SYSTEM

The Japanese “just-in-time with kanban” technique reduces in-process inventory to absolute minimal levels, in concert with the Japanese belief that inventory is an unnecessary evil. Due to the success of Japanese firms that employ this type of system, American firms would like to import this technique and emulate Japanese successes. But this Japanese success may be attributable not only to the just-in-time with kanban technique but also to the production environment in which the technique is employed. This paper simulates the just-in-time with kanban technique for a multiline, multistage production system in order to determine its adaptability to an American production environment that might include such characteristics as variable processing times, variable master production scheduling, and imbalances between production stages. The results have practical implications for those firms considering adoption of the Japanese technique.     

先秦兵家军事立法理念初探

兵家军事立法理念兼具理想性和现实性,既讲求战争和法律的正义性与合人心性,也研究作战指导、治军方案的可行性与可操作性。兵家对治军中的“礼”与“法”的相互关系已有清醒的认识,并积极提倡和重视教化与刑罚的结合,即“令之以文,齐之以武”。在兵家看来,“礼”的要求也是“法的内容”,“礼”与“法”各有所用,只有礼、法并用,才能治理好军队。     

从区域文化角度比较唐浩明与二月河历史小说的差异

唐浩明、二月河是当代历史小说创作的两位突出代表,理论界对两者历史小说的批评一般停留在历史真实与艺术真实的结合和雅俗定位上,缺乏针对性。笔者认为唐浩明、二月河的创作都受到区域文化的影响,湖湘文化的"经世致用"与河东风土的"重实轻名",是使唐浩明与二月河的文学作品在创作动机、艺术品位等方面产生差异的重要原因。

Characterizations based on conditional expectations

For given real functionsg andh, first we give necessary and sufficient conditions such that there exists a random variableX satisfying thatE(g(X)|X≥y)=h(y)r _x (y),∀y ∈ C _x , whereC _x andT _X are the support and the failure rate function ofX, respectively. These extend the results of Ruiz and Navarro (1994) and Ghitany et al. (1995). Next we investigate necessary and sufficient conditions such thath(y)=E(g(X)|X≥y), for a given functionh. Support for this research was provided in part by the National Science Council of the Republic of China, Grant No. NSC 86-2115-M-110-014 and NSC 88-2118-M-110-001     

Quantile regression for large-scale data via sparse exponential transform method

In recent decades, quantile regression has received much more attention from academics and practitioners. However, most of existing computational algorithms are only effective for small or moderate size problems. They cannot solve quantile regression with large-scale data reliably and efficiently. To this end, we propose a new algorithm to implement quantile regression on large-scale data using the sparse exponential transform (SET) method. This algorithm mainly constructs a well-conditioned basis and a sampling matrix to reduce the number of observations. It then solves a quantile regression problem on this reduced matrix and obtains an approximate solution. Through simulation studies and empirical analysis of a 5% sample of the US 2000 Census data, we demonstrate efficiency of the SET-based algorithm. Numerical results indicate that our new algorithm is effective in terms of computation time and performs well for large-scale quantile regression.
