LOGISTICS SALIENCE IN A CHANGING ENVIRONMENT

The primary purpose of this paper was to empirically explore some of the reasons that logistics has become more important, or salient, in comparison to other functions within the firm. A survey of 296 managers across multiple industries in the U.S. found logistics becomes more important within the firm when the industry increases in uncertainty, when there is an emphasis on time‐based competition, when there is greater adoption of information technology, and when there is an emphasis on cross‐functional integration.

农村集体建设用地流转地权的激励模式

农村集体建设用地流转中存在严重的资金时差悖论,导致难以利用集体土地本身进行融资,土地整理融资难反过来又成为阻碍集体建设用地流转的瓶颈性因素。现有流转模式难以协调各种利益,不能对流转各方产生足够激励,变相征地的方式削弱了农民的土地持续收益能力,未能真正实现城乡建设用地"同质、同价、同权"。因此,应根据利益协调的原则创新制度设计,以地权激励引导社会资源投入,促进集体建设用地顺畅流转。     

人民币实际有效汇率的变化对我国进出口的影响

本文从空间和时间两个角度全面考察了人民币实际有效汇率的变化对我国进出口的影响。结果表明,人民币汇率的变化会显著影响我国的进出口。但是,这种影响程度在1994年以后明显地出现了下降趋势。同时,人民币汇率变化对我国进出口的调整存在明显的J曲线效应,其中进口变动大致滞后于汇率变动2个季度,而出口则滞后1个季度,滞后期限均短于西方发达国家。本文分析了其中的原因并提出了相关建议。

中国私募基金运作机制研究

私募基金是相对于公募的共同基金而言的一种基金类型，这种基金属于一种合伙人制的小型私人投资公司，主要投资于公开交易的证券和衍生金融产品，是一种高风线的投机基金。随着证券市场改革的深入，私募基金面临的环境发生了重大变换，本文从研究美国私募基金运作机制入手，探讨适合中国私募基金运作的机制，以规范和发展我国的私募基金。     

Residential Asking Rents and Time on the Market

Landlords offering a house in the rental market face a difficult strategic pricing decision. The revenue maximizing decision for the landlord involves a tradeoff between the rental rate and time on the market. Because the turnover of renters is higher than owners, and because the landlord must bear some carrying costs on a vacant house, pricing the rent too high may decrease revenue due to a higher vacancy period and pricing it too low may reduce the revenue when occupied. While there is substantial research on the relationship between listed prices and time on the market for freehold interests, this is the first study to provide empirical evidence on the relationship between asking rent, contract rent and time on the market for single family residential rental (leasehold) property interests. We present two models; a rental price model and a duration model for time-on-the market. Using data from the Dallas–Fort Worth area we find that landlords who set a lower asking rent relative to predicted rent can expect a shorter marketing period for their properties. The results also indicate that overpricing the asking rent and then lowering it at a later date leads to a longer marketing time (after the reset) and often a lower rent. These finding are reasonably robust for low-, mid-, and higher-valued rental properties.

An empirical investigation of water consumption forecasting methods

Many regions on earth face daily limitations in the quantity and quality of the water resources available. As a result, it is necessary to implement reliable methodologies for water consumption forecasting that will enable the better management and planning of water resources. This research analyses, for the first time, a large database containing data from 2 million water meters in 274 unique postal codes, in one of the most densely populated areas of Europe, which faces issues of droughts and overconsumption in the hot summer months. Using the R programming language, we built and tested three alternative forecasting methodologies, employing univariate forecasting techniques including a machine-learning algorithm, with very promising results.     

Forecasting UK house prices: A time varying coefficient approach

Previous studies of UK house prices, developed from the demand and supply ofhousing or from the asset market approach have been poor in terms of robustness and ex-post forecasting ability. The UK housing market has suffered a number of structural changes, particularly since the early 1980s with substantial house price increases, financial market deregulation and the removal of mortgage market constraints through competition. Consequently, models which assume that the underlying data-generating process is stable and apply constant parameter techniques tend to suffer in terms of parameter instability. This article uses the Time Varying Coefficient (TVC) methodology where the underlying data-generating process in the UK housing market is treated as unstable. The estimation results of the TVC regression of UK house prices is compared with those obtained from three alternative constant parameter regressions. Comparisons of forecasting performance suggest the TVC regression out-performs forecasts from an Error Correction Mechanism (ECM), Vector Autoregressive (VAR) and an Autoregressive Time Series regression.     

手术在治疗跟骨关节内骨折28例的临床效果

目的探讨手术治疗根骨关节内骨折的临床疗效。方法本选取2009年12月～2011年12月我院收治的跟骨关节内骨折患者28例的临床资料。按其来院顺序,将其随即分为两组,切开复位内固定组(A组)和改良式复合外固定支架固定组(B组),每组患者均为14例。比较两组的临床疗效。结果 A组治疗在SandersⅡ型上,其优良率好于B组,且差异具有统计学意义(x2=8.45,P<0.05)。两组在SandersⅢ型-Ⅳ型的治疗上,B组好于A组,差异具有显著统计学意义(x2=14.36,P<0.01)。结论切开复位内固定和改良式复合外固定支架固定治疗根骨关节内骨折临床疗效均较好,且操作简单,并发症少,值得在临床中广泛应用。
