摘要：
Many IT companies like HP, Dell and Lenovo have established both English language and Chinese user support forums for their consumers to share and construct knowledge. The innovative knowledge generated in these virtual product user communities is valuable for companies enabling them to incorporate users’ innovative insights and problems solving skills. This research compares the knowledge construction processes within such forums in English and Chinese cultural contexts. The research adopts a method combining content analysis of discussion threads where technical problems are solved, complemented by observation and thematic analysis of interviews with forum members. The results show that the cultural and language differences do not cause a big change of users’ knowledge construction patterns. However, the character of Chinese language and culture can indirectly affect the process by including more social information to influence social interactions. The research suggests that more tailored facilitation strategies should be adopted in managing producer sponsored user support forums designed for different cultural regions.

摘要：
Ultrafine particles with a diameter below 1 μm are strongly linked to traffic and industrial emissions, causing a growing global health concern. In order to reveal the characteristics of ultrafine particles in central China, which makes up the sparse research in industrial cities of a developing country, particle number concentrations (PNC) together with meteorological parameters and concentrations of trace gases were measured over one year inWuhan. The number concentration of ultrafine particles peaked in winter and was the lowest in summer across the entire size range monitored. Further, particles with a diameter smaller than 30 nm increased dramatically in concentration with decreasing diameter. The monthly averaged number concentrations of particles discriminated in three size ranges formed a near- inverse parabolic distribution peaking in January. This trend is supported by a negative correlation between PNC and precipitation, temperature, and mixing layer height, which emphasizes the effect of these meteorological parameters on scouring, convection, and diffusion of particles. However, since wind not only disperses particulate matter but also brings in exogenous particles, wind speed plays an equivocal role in particle number concentrations. The diurnal analysis indicates that hourly measurements of trace gases concentrations could be used as a proxy for dense industrial activities and to reveal some complex chemical reactions. The results of this study offer reasonable estimations of particle impacts and provide references for policymaking of emission control in the industrial cities of developing countries.

automated trust negotiation;mobile commerce;negotiation strategy;Petri net
摘要：
Automated trust negotiation (ATN) offers an attractive means for trust establishments, which establishes mutual trust among strangers wishing to share resources or conduct business, but it comes at the cost of non-trivial computation and communication overheads. The deployment of ATN strategies on a resource-constrained mobile device may lead to user-obstructive latency for operations. In this paper, we propose a trust negotiation strategy called trust target Petri nets negotiation strategy (TPNNS). It highly reduces the negotiation latency in the mobile device compared with other negotiation strategies, since it considers all the alternative responses at each step and chooses the best one. TPNNS supports cycle avoidance and employs skipped TPN which is a new approach presented in this paper. What is more, it is complete and ensures no irrelevant credentials are disclosed during the trust negotiation.

passenger flow management;oscillations extracting;operation of airports;forecasting and decision-making
摘要：
Managing air passenger traffic flows is important in investing and operation of airports. However, it is extremely difficult for traditional methods to analyse passenger traffic in both the short and medium terms because of the oscillation and irregularity inherent in air passenger traffic flows dynamics. In this study, we design a hybrid oscillations analysis approach. The proposed method decomposes time series into different scales, making it useful in revealing structural breaks and volatility clusters, and identifying dynamic properties of a process at specific timescales. A case study of Hong Kong airport demonstrates and validates the feasibility of applying the proposed models. Empirical results have confirmed that the proposed model is superior to other competing models and can provide high flexibility in decision-making.

摘要：
We investigated a topic-based navigation guidance system in the World Health Organization portal, compared the link connection network and the semantic connection network derived from the guidance system, analyzed the characteristics of the 2 networks from the perspective of the node centrality (in_closeness, out_closeness, betweenness, in_degree, and out_degree), and provided the suggestions to optimize and enhance the topic-based navigation guidance system. A mixed research method that combines the social network analysis method, clustering analysis method, and inferential analysis methods was used. The clustering analysis results of the link connection network were quite different from those of the semantic connection network. There were significant differences between the link connection network and the semantic network in terms of density and centrality. Inferential analysis results show that there were no strong correlations between the centrality of a node and its topic information characteristics. Suggestions for enhancing the navigation guidance system are discussed in detail. Future research directions, such as application of the same research method presented in this study to other similar public health portals, are also included.
摘要：
In the current business environment, both managers and researchers have realized that assessing and managing risk in a supply chain operation is crucial to business success. Furthermore, the traditional assessment methodologies are unable to deal with intangible criteria which are crucial factor in the analysis. Thus, we develop an orders-of-magnitude AHP (OM-AHP) based ex-ante supply chain risk assessment model, to enable the comparison of the tangible and intangible elements that influence supply chain risks. In the application of OM-AHP method to risk assessment it also became apparent a formal guiding structure of how to pivot using OM-AHP did not exist. A formal method is proposed that can significantly reduce the number of needed comparisons and improve the consistency with pairwise comparisons matrices under any AHP decision. The process of the proposed supply chain risk assessment framework consists of three phases: risk identification, risk assessment, and risk ranking and analysis. An illustrative example is provided to demonstrate the efficacy of the proposed risk assessment framework. The results are organized in a 2-way risk matrix based on their probability and consequence severity and tested for robustness via sensitivity analysis.(C) 2016 Elsevier B.V. All rights reserved.

Consensus reaching;Group decision making;The Analytic Hierarchy Process (AHP);Weight determination
摘要：
Consensus reaching models are widely applied in group decision making problems to improve the group's consensus level before making a common decision. Within the context of the group Analytic Hierarchy Process (AHP), a novel consensus reaching model in a dynamic decision environment is proposed. A Markov chain method can be used to determine the decision makers' weights of importance for the aggregation process with respect to the group members' opinion transition probabilities. The proposed group consensus reaching model facilitates a peer to peer opinion exchange process which relieves the group of the need for a moderator by using an automatic feedback mechanism. Moreover, as the elements in the group decision framework change in a dynamic decision making problem, this model provides feedback suggestions that adaptively adjust for each of the decision makers depending on his credibility in each round. The full process of the dynamic adaptive consensus reaching model is presented and its properties are discussed. Finally, a numerical example is given to demonstrate the effectiveness of our model.

Financial market fluctuation;Multiple dimensioned mining;Radial basis function network
摘要：
Fluctuation mining is one of the greatest challenging tasks in the field of finance market. The main contribution of this research was to propose a multiple dimensioned model for financial market fluctuation mining. In this approach, the original financial time series is broken down into different information by the wavelet filtering technique, and then, all this information is handled through radial basis function networks due to its universal approximation abilities and more robust than the ordinary networks. An experimental analysis is conducted with the proposed model using stock index future time series, revealing consistent performance improvement of this kind of multidimensional approach.

摘要：
In the process of coverage for multiple targets, the existence of a large number of redundant data decreases the effective coverage of monitoring area and increases the energy consumption of network. Therefore, this paper proposes a Multi-Targets K-Coverage Preservation Protocol (MTCPP). Firstly, the de-pendency of sensor nodes and target nodes is established by the network model, and the method of monitoring region coverage is given. Secondly, the network energy balance is achieved by using sensor node scheduling mechanism. Finally, the simulation experiments show the protocol can effectively reduce the number of active nodes and improve the network lifetime.

摘要：
Robust small target detection of low signal-to-noise ratio (SNR) is very important in infrared search and track applications for self-defense or attacks. Consequently, an effective small target detection algorithm inspired by the contrast mechanism of human vision system and derived kernel model is presented in this paper. At the first stage, the local contrast map of the input image is obtained using the proposed local contrast measure which measures the dissimilarity between the current location and its neighborhoods. In this way, target signal enhancement and background clutter suppression are achieved simultaneously. At the second stage, an adaptive threshold is adopted to segment the target. The experiments on two sequences have validated the detection capability of the proposed target detection method. Experimental evaluation results show that our method is simple and effective with respect to detection accuracy. In particular, the proposed method can improve the SNR of the image significantly.

摘要：
Many women wear high heeled shoes (HHS) on a daily basis to increase the femininity and attractiveness, making these shoes remain popular despite the negative effects surrounding HHS. This study aimed to investigate the effects of HHS wearing experience and heel height on human stability and foot plantar pressure distribution. Thirty young healthy women consisted of two groups, inexperienced and experienced high-heel wearers, participated in a standing balance test to measure their foot plantar pressures and stability limits when they wore shoes of four different heel heights: 0cm (flat), 4cm (low), 7cm (medium), and 10cm (high). Experimental results showed that the increased heel height shifted the force and peak pressure from the rear foot and mid foot regions to the forefoot and toe regions and the center-of-pressure location moved towards medial anterior side of the foot. Human stability limits were worsened significantly with the increased heel height, especially when it reached 7cm. HHS wearing experience provided certain advantages to the wearers on plantar pressure distributions and the limits of stability, shown by more appropriate pressure distributions and larger excursions and better directional controls in the forward and back directions.
