Determinants of demand for international tourist flows to Turkey

This article describes the development and findings of a set of models used to identify the most important of the following selected variables influencing international tourist flows to Turkey: per capita income; relative prices; relative exchange rate; promotional expenditure (the Turkish Government has invested a substantial amount in promoting foreign tourism) and ‘special events’, eg political unrest. The demand for travel was measured both by the number of tourists, and by the total tourist expenditure. Data were obtained from secondary sources, and analysis was by least squares multiple regression. Income, price and exchange rate were found to be important factors but the impact of promotional expenditure was minimal     

巴江口水电站综合办公楼防雷设计方案

随着现代社会的发展，建筑物的规模不断扩大，其内各种电气设备的使用日趋增多，尤其是随着计算机网络信息技术的普及，建筑物越来越多采用各种信息化的电气设备。广西每年因雷击破坏建筑物内电气设备的事件时有发生，所造成的损失非常巨大。因此，建筑物的防雷设计显得尤为重要。笔者结合实际工作，以巴江口水电站综合办公楼防雷设计为例，提出建筑物综合防雷工程设计方案。     

Context sensitive multimodal road planning: a case study in Cape Town, South Africa

Road planning practice relies almost exclusively on parameters related to traffic factors, such as private vehicle speeds and volumes. In many developing countries the requirements for public transport and non-motorised transport are not explicitly integrated into the planning process, despite the fact that these form the primary mode of transport for the majority of the population. This affects the mobility opportunities for these sectors of the population and contributes to poor road safety, especially with regards to pedestrians. The research outlined in the paper posits that, in order to assess the usage and needs of the road holistically, other factors related to the adjacent land uses, socio-economic characteristics of the population the road serves, and the environmental context within which the road is located, factors heavily in how the road is used and should, therefore, be considered within the planning process. The paper describes a methodology to include these factors in the planning of roads. The method attempts to prioritise amongst the five primary road based modes (public transport, car, freight, walking and cycling) based upon a combination of traffic and non-traffic factors. The method employed uses a geographic information system (GIS) based spatial multiple criteria evaluation (SMCE) model with inputs from widely available data sources such as census, household travel surveys, land use and environmental data to arrive at solutions for modal priorities. A case study is conducted along an arterial route in Cape Town, South Africa, providing infrastructure planning recommendations and audit possibilities for the future. Since weighting is an important driver in the SMCE process, a sensitivity analysis is conducted to investigate the effect of alternative weighting schemes on the outputs from the method.     

Can an Unemployment Insurance System Generate Multiple Natural Rates?

This article studies some macroeconomic consequences of the financing of an unemployment insurance scheme. Under a balanced-budget rule, when both taxes and unemployment benefits are proportional to wages, the existence of multiple natural rates of unemployment is a generic property of the matching model. Government can lead the economy to a high equilibrium by fixing the rate of tax on wages and then setting the replacement ratio so that its expenditure matches its receipts.     

Multiple Bids, Management Opposition, and the Market for Corporate Control

We use regression analysis to disentangle the wealth effect for acquired firm shareholders of management opposition and multiple bids (e.g., multiple bidders and bid revisions). Although multiple bidders and bid revisions occur more frequently for opposed acquisitions, opposition is not associated with incremental acquisition returns for acquisitions with multiple bidders. We also find that management opposition has no significant incremental effect on single bidder acquisitions unless the acquiring firm revises its initial bid. These findings indicate that rather than amplifying acqiuisition returns directly, management opposition instead serves as a negotiating tool to solicit additional bids.     

一种基于小波域的盲水印算法

提出了一种基于小波变换后频域系数的特征以及水印图像数据的奇偶性盲水印算法。该算法先将图像进行两级小波变换，根据LL2中数据特点和水印数据的奇偶性在HL2、LH2、HH2嵌入水印。在检测水印的时候，只需要拥有少量数据，就可以完成水印的提取。攻击实验研究表明：此算法具有很好的抗规则剪切、不规则剪切、加噪、压缩的能力，具有很好的鲁棒性。     

椭圆半带滤波器及其在小波包谐波分析中的应用

小波包分解因为具有较高频谱分析的精度，在电力系统谐波检测中得到了广泛的应用．但其复杂的计算使它在实时的测量中受到了限制．现提出了将IIR椭圆半带滤波器应用于小波包谐波分析中的新方法，通过研究表明，该算法可以将复杂的计算减少到与快速傅立叶变换（FFT）同等数量级上．仿真和实验结果进一步表明了该算法的有效性．     

金融危机正在改变世界

当前金融危机是经济周期的必然结果，其直接原因是以美元为核心的单体国际货币体系和保护主义日益严重导致的全球经济的长期失衡，要通过这场金融危机来平衡全球金融体系和经济的关系。因此，建立多元的国际货币体系，是这次金融危机之后最重大的金融制度的变革。目前金融还是现代经济的核心和心脏，不能因为金融危机而停止中国金融的市场化改革的步伐；同时，金融危机给中国带来了两个难得的机遇，即人民币的国际化和全球金融中心的构建。

基于多元线性回归的装饰工程快速估价模型

针对目前装饰工程陕速估价方法的不足，以及装饰工程造价组成的特点，建立一种基于多元线性回归的快速估价新模型。以住宅类建筑为例，建立其多元线性回归模型，结合SPSS软件对样本分析，结果表明，其线性回归模型显著，同时，内墙、外墙、楼地面和窗的回归系数也非常显著。通过计算回归值与实际值的误差，发现误差比较理想，该模型具有很好的实用价值。
