Housing Choice in an Affluent Shanghai – Decision Process of Middle Class Shanghai Residents  [PDF]
L. H. Li
Modern Economy (ME) , 2011, DOI: 10.4236/me.2011.21002
Abstract: While most papers on housing choice concentrate on relatively disadvantaged groups in the society con-strained by financial ability, this paper looks at the affluent population in Shanghai. In examining their own perception of the relative importance of difference factors affecting such choice by way of an Analytical Hi-erarchy Process, we are able to understand that currently, most affluent households still regard proximity to the city centre as an important factor when making housing choice. More importantly, there seems to be a marked difference in the ranking of these factors between the upper middle class and the average middle class in this city. Our analysis shows that the upper middle class households place more importance on the transportation network and neighbourhood infrastructure, while the average middle class have more concern on the housing attributes.
Physical and Electrical Performance of Vapor–Solid Grown ZnO Straight Nanowires
Li JY,Li H
Nanoscale Research Letters , 2008,
Abstract: Physical and electrical properties of wurtzitic ZnO straight nanowires grown via a vapor–solid mechanism were investigated. Raman spectrum shows four first-order phonon frequencies and a second-order Raman frequency of the ZnO nanowires. Electrical and photoconductive performance of individual ZnO straight nanowire devices was studied. The results indicate that the nanowires reported here are n-type semi-conductors and UV light sensitive, and a desirable candidate for fabricating UV light nanosensors and other applications.

The role of the parents in influencing children is very important, in terms of the value system, attitude and behaviour. The importance and values of health are recognized by Hong Kong people, the development of an active lifestyle and exercise habit is relatively unsatisfactory. In Hong Kong, the Sport for All movement has been implemented by the SAR Government of Hong Kong for 40 years, but recent researches showed that more than 60% of the population didn’t exercise adequately. This suggested that alternative means to promote the sport for all were desirable. The health practices namely, exercise frequency, snack habit, breakfast habit, regular meals, sleeping hours, drinking habit, smoking habit, medication taking, exercise and medical expenditures of 919 randomly and systemically selected subjects aged 40 - 59 years were assessed. For each health practice, gender differences were analyzed using Cramer’s V and Ward Linkage method (cluster) was used to assess their cluster membership.

Foreign Currency Derivatives and Firm Value: Evidence from New Zealand  [PDF]
Hao Li, Nuttawat Visaltanachoti, Robin H. Luo
Journal of Financial Risk Management (JFRM) , 2014, DOI: 10.4236/jfrm.2014.33010
Abstract: The benefit of corporate hedging remains controversial. While hedging could reduce the likelihood of adverse outcome, it will incur additional costs that may offset such benefit. This study provides some evidences to resolve the debate. We examine the benefits of foreign currency derivatives usage in 134 non-financial firms listed on the New Zealand Stock Exchange. New Zealand dollar experiences relatively high volatility so it is an ideal setting to examine whether the currency derivative usage could add value to the firm. Using Tobin-Q and other of its variants as a proxy of firm value, we find no evidence supporting the notion that the use of foreign currency derivatives can enhance a firm value.

Quantitative analysis on the ecological impact of large-scale water transfer project on water resource area in a changing environment
D. H. Yan,H. Wang,H. H. Li,G. Wang
Hydrology and Earth System Sciences Discussions , 2011, DOI: 10.5194/hessd-8-10465-2011
Abstract: The interbasin long-distance water transfer project is a key support for the reasonable allocation of water resources in a large-scale area, which can optimize the spatiotemporal change of water resources to reinforce the guarantee of the access of water resources. And large-scale water transfer projects have a deep influence on ecosystems; besides, global climate change causes the uncertainty and additive effect of the ecological impact of water transfer projects. Therefore, how to assess the ecological and environmental impact of large-scale water transfer projects in both construction and operation has triggered a lot of attention. The water-output area of the western route of China's South-North Water Transfer Project was taken as the study area of the present article. According to relevant evaluation principles and on the basis of background analysis on the eco-environment of the study area, the influence factors were identified and evaluation indexes were established. The climate-hydrology-ecology coupled simulation model was used to imitate the laws of ecological and environmental change of the water resource area in a changing climate. The emphasis of influence analysis and quantitative evaluation was placed on the reservoir construction and operation scheduling, representative river corridors and wetlands, natural reserves and the water environment of river basins below the dam sites. In the end, an overall influence evaluation of the impact of the project on the water circulation and ecological evolution of the water resource area was conducted. The research results were as follows: the environmental impacts of the western route project in the water resource area were concentrated on two aspects, i.e. the permanent destruction of vegetation during the phase of dam construction and river impoundment, and the significant influence on the hydrological situation of natural river corridor after the implementation of water transfer. Its impact on local climate, vegetation ecology, typical wetlands, natural reserves and the water environment of river basins below the dam sites was small.
Voltage Sags Matching to Locate Faults for Underground Distribution Networks
Advances in Electrical and Computer Engineering , 2011, DOI: 10.4316/aece.2011.02007
Abstract: A voltage sags matching to locate a fault for underground distribution network is presented in this paper. Firstly the method identifies the faulted section by matching a voltage sags measured at the primary substation during a fault with pre-developed voltage sag database. From the identified faulted section, the distance of a fault from sending-end is calculated. The problem of multiple sections is addressed by ranking approach. Test results on an underground distribution network shows most faults can be located by the first attempt within high accuracy distance. Only few faulted sections found by the second attempt. Since the method is using only voltage sag data, monitored at the primary substation, the method is considers economical to be implemented for a rural distribution network.
The Energy-Efficient Processing of Fine Materials by the Micropyretic Synthesis Route
H. P. Li
Journal of Nanomaterials , 2012, DOI: 10.1155/2012/727656
Abstract: Energy-efficient processing of TiB compound with nanowhiskers by micropyretic synthesis is investigated in this paper. Micropyretic synthesis not only offers shorter processing time but also excludes the requirement for high-temperature sintering and it is considered as the one of the novel energy-saving processing techniques. Experimental study and numerical simulation are both carried out to investigate the correlation of the processing parameters on the microstructures of the micropyretically synthesized products. The diffusion-controlled reaction mechanism is proposed in this study. It is noted that nanosize TiB whiskers only occurred when the combustion temperature is lower than the melting point of TiB but higher than the extinguished temperature. The results generated in the numerical calculation can be used as a helpful reference to select the proper route of processing nanosize materials. The Arrhenius-type plot of size and temperature is used to calculate the activation energy of TiB reaction. In addition to verifying the accuracy of the experimental measures, the reaction temperature for producing the micropyretically synthesized products with nanofeatures can be predicted.
