Microbial fuel cells (MFCs) represent a new biological method for generating electricity directly from biodegradable compounds. Efficiency of MFCs using manure as substrate is generally low. This study proposed a new design by incorporating biocathodes into a three-chamber MFC, which yielded maximum power densities much higher than those reported in literature. The new design placed cylindrical anode chamber for easy stirring and two symmetrical cathodic chambers with reduced anode-cathode distance. The biocathodes were applied to reduce charge transfer resistance. Additionally, biocathode microbial community was cultured to enrich favorable microorganisms. With external loading of 100Ω, the power densities for new biocathode MFC using 2, 4, 6, 8 and 10% total solids diary manure reached 7.85±1.0Wm -3, 7.84±1.20Wm -3, 8.15±0.20Wm -3, 7.60±0.97Wm -3 and 5.63±0.97Wm -3, respectively. The pH drop as a result of manure hydrolysis limited the power output. To provide detailed information of the microbial community in the biocathode MFC, the 454-pyrosequencing technique was adopted. The Firmicutes, γ-, β-, α- and δ-Proteobacteria, Bacteroidetes and Actinobacteria were the major groups on the anode, while γ-, β-, and α-Proteobacteria, Bacteroidetes and Actinobacteria were the predominant groups on the cathode. © 2011 Elsevier B.V.

Microbial fuel cells (MFCs) with abiotic cathodes require expensive catalyst (such as Pt) or catholyte (such as hexacynoferrate) to facilitate oxidation reactions. This study incorporated biocathodes into a three-chamber MFC to yield electricity from sewage sludge at maximum power output of 13.2±1.7W/m 3 during polarization, much higher than those previously reported. After 15d operation, the total chemical oxygen demand (TCOD) removal and coulombic efficiency (CE) of cell reached 40.8±9.0% and 19.4±4.3%, respectively. The anolyte comprised principally acetate and propionate (minor) as metabolites. The use of biocathodes produced an internal resistance of 36-46Ω, lower than those reported in literature works, hence yielding higher maximum power density from MFC. The massively parallel sequencing technology, 454 pyrosequencing technique, was adopted to probe microbial community on anode biofilm, with dominant phyla belonging to Proteobacteria (45% of total bacteria), Bacteroidetes (19%), Uncultured bacteria (9%), Actinobacteria (7%), Firmicutes (7%), Chloroflex (7%). At genera level, Rhodoferax, Ferruginibacter, Propionibacterium, Rhodopseudomonas, Ferribacterium, Clostridium, Chlorobaculum, Rhodobacter, Bradyrhizobium were the abundant taxa (relative abundances>2.0%). © 2011 Elsevier Ltd.

The accurate estimation of the point spread function (PSF) of degradation model is the key point in image restoration. Aiming at the fact that the blur PSF parameters of uniform linear motion are unknown, a blur parameter estimation method is proposed based on frequency spectrum correlation coefficient analysis with reference image. Specifically, using the motion blur direction property of the blurred image twice Fourier transform spectrum, a clear reference image is blurred with a fix blur length and various blur directions, and then the blur direction estimation is achieved through analyzing the spectrum correlation maximum between the blurred reference image and the image to be restored. The direction error can be limited in a small range by using a defined adjustment matrix. Furthermore, the motion blur direction and blur length can be calculated accurately by analyzing the spectrum correlation in Fourier frequency domain. The experiment results show that for noise free blurred image, there are no direction and length estimation errors in any direction and within the blur length range of 10

With the rapid business expansion in China, multinational logistics companies are desperately in need of local management personnel to staff new offices and routes. This has been a major challenge for multinational logistics enterprises, as finding qualified candidates, recruiting them, and retaining them in China have proven to be harder than expected. Based on a set of interviews with executives in global logistics companies as well as interviews with Chinese supply chain candidates, we explore a set of root causes that underlie the challenges that human resource (HR) managers in multinational logistics companies face when recruiting and retaining Chinese employees. These underlying causes are manifold in nature. First, there is a shortage of qualified graduates from universities for open roles in logistics enterprises partly due to the nascent logistics higher education in China. Second, multinational logistics enterprise roles are often less appealing to talented Chinese job candidates who have multiple options for logistics career opportunities. Third, there is a gap between the expectations of Chinese employees and the perceived reality of foreign managers relative to what constitutes competitive salary, benefits, and job satisfaction conditions. To address the logistics labour challenges, it is imperative that Western logistics enterprises operating in China align their HR strategies and tactics with the hard realities of the Chinese labour pool and the conditions that exist in the market today as well as the near future. We identify several approaches to close the gap that exists today, including (a) creating training opportunities for HR managers on Chinese culture and social contexts, (b) establishing fair incentives internally, and (c) seeking deeper and broader relationships with Chinese universities to attract talent. © 2012 Copyright Taylor and Francis Group, LLC.

The accurate estimation scheme of point spread function (PSF) is very important for obtaining good restoration performance in image restoration. For the unknown blur parameter of a single defocus image, an estimation method is proposed. First, polar transformation is applied to the logarithmic power spectrum of the defocus image in the frequency domain. Then the defocus blur radius can be obtained by calculating the sum of the logarithmic spectrum along concentric circles in the polar coordinate. The experiment results show that for noise free blurred images, the method can achieve more accurate estimation of the point spread function within the blur radius range of 0

In recent years, online group purchase companies are thriving. In group purchase, according to the thirddegree price discrimination principle, consumers get extra utility, and at the same time new areas of growth are created by merchants. Thus, third-degree price discrimination strategy can enhance both market efficiency and social welfare. In this research, the game theory model and the utility function are used to show that online group purchase can not only improve producers and consumers' welfare, and also promote social welfare.

Unlike traditionally used reserves models, this paper focuses on a reserve process with dynamic income to study the reinsurance-investment problem for an insurer under Vasicek stochastic interest rate model. The insurer's dynamic income is given by the remainder after a dynamic reward budget being subtracted from the insurer's net premium which is calculated according to expected premium principle. Applying stochastic control technique, a Hamilton-Jacobi-Bellman equation is established and the explicit solution is obtained under the objective of maximizing the insurer's power utility of terminal wealth. Some economic interpretations of the obtained results are explained in detail. In addition, numerical analysis and several graphics are given to illustrate our results more meticulous.

We discuss an application of conjoint analysis in technology forecasting, summarize basic operation steps of conjoint analysis, and give a stimulant example of technology forecasting. In this example, we consider five factors that will affect the emergence of a new technology. These factors have investing demand in a new technology, potential market value of a new technology, realizable difficulty of a new technology, supporting degree of relative technology to a new technology, and the competitive power of a new technology with original technology. Technology development has a discontinuity. With discontinuity, we cannot forecast the future of technology development, based on the current trend of technology development. As using quantitative methods to make forecasting, we assumed that current trends of technology development hold a fixed law, so those quantitative methods cannot forecast the discontinuity of technology development. Some subjective forecasting methods have huge improvement in technological discontinuity forecasting. The improvement is that forecaster's subjective judgments and capability are embodied in forecasting. But this method has two inherent defects: one is the lack of design ability, which makes this method susceptible to the influence of organizer and forecasting, and the other is that while facing numerous forecasters, the forecasting data are often difficult to explain and analyze; we also have difficultly in making a synthesized judgment. A subjective and synthesized judgment of technology development is similar to economical utility, thus we could apply the measure of colony's utility to improve the appropriateness and reliability of subjective forecasting method. Using conjoint analysis, we can judge the colony's utility accurately, because the datum that we use in analysis comes from the subjective judgments of forecasters to various fields of technical development, but the influence of the random error can be dispelled by using some theory model about data processing. Therefore, conjoint analysis method is one useful tool for technology forecasting. The effectiveness of this method has been testified by simulation experiment. © Springer Science+Business Media, LLC 2011.

The study on the relationship between the resources development and the economic development has been a hotly debated topic. The traditional economic theory emphasized the positive role of the abundant natural resources in regional economic development, while resource course theory holds the opposite view. Taking Shanxi province which is abundant of coal resource as an example, this paper analyzes empirically the relationship between the coal resource development and the economic development by using the panel data model. The result shows that there is no significant correlation between the abundance of coal resource and the economic development. © 2011 Published by Elsevier Ltd.
