Shopping System Model in Electronic Commerce

Despite its name, e-commerce is not fully automated. Typically, online transactions require a significant level of human intervention. Customers undertake the search for products, services, potential vendors and business partners. They evaluate alternatives, decide what goods to buy and when, from which vendor, and how much they are willing to pay for. They engage in potential negotiations, carry out the transactions and so on. As those markets become mature, new products and services, as well as new practi...     

现代战争模拟研究的新方向：社会仿真

随着世界社会经济和科技水平的不断发展,特别是现代信息技术的发展,社会因素对战争的影响越来越突出,因此,战争模拟应该把视野扩展到传统研究之外的社会领域.主要阐述社会仿真概念的基本内涵,建模仿真基本方法,然后重点介绍社会仿真研究领域的基础设施建模研究、大规模群体行为建模研究以及国内外典型的大规模社会仿真系统,最后,介绍在该领域开展的部分研究工作,并指出我国在该领域展开研究工作的重要意义.     

一种增量式的社区发现算法研究

传统社区发现算法基本上属于静态的分析算法,其计算复杂性使其难以适应目前网络结构的频繁变化.为了改善静态算法的这一局限性,通过对Radiechi静态算法进行扩展,提出一种增量式的社区发现算法,并将其应用于MSN Space链接结构分析上.该算法能在网络结构变化频繁时进行增量式计算并保证社区发现的实时性.实验结果表明,该增量式算法在处理网络结构变化时的效率相对传统算法有显著提高,尤其对小规模频繁变化的网络有很强的适应力.     

Rigor, rigor mortis, and conspiratorial views of depression research.

The authors reassert the need for methodological changes in depression research appearing in the Journal of Personality and Social Psychology and other personality and social psychology journals. In this rejoinder the authors update their earlier literature review (H. Tennen, J. Hall, & G. Affleck; see record 1995-31710-001) and respond to the commentaries by P C. Kendall and E. C. Flannery-Schroeder (see record 1995-31700-001) and G. Weary, J. A. Edwards, and J. A. Jacobson (see record 1995-31713-001). The authors notice that G. Weary et al.'s own findings demonstrate the need to change how depression is measured and participants are assigned to experimental groups. The authors also challenge G. Weary et al.'s contention that structured interviews are limited because they require interviewer judgments, and they urge personality and social psychologists to learn more about these interviews. Finally, G. Weary et al.'s suspicion that depression research guidelines reflect professional parochialism is disputed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Do social media literacy skills help in combating fake news spread? Modelling the moderating role of social media literacy skills in the relationship between rational choice factors and fake news sharing behaviour

This study modelled the rational factors that predict fake news sharing behaviour. It also tested the moderating role of social media literacy skills. The focus was on social media users in Nigeria. An online survey was conducted to gather the responses from participants across Nigerian geopolitical zones. Structural equation modelling (SEM) Smart PLS 3.6 was used to analyse the data. We found that information sharing, the news finds me perception, trust in social media and status-seeking lead to fake news sharing among social media users in Nigeria. Specifically, trust in social media and status-seeking had a greater effect on fake news sharing behaviour. We also found that social media literacy skills significantly moderate the relationship between information sharing, status-seeking, the news finds me perception, trust in social media and fake news sharing in such a way that the effects/relationships are stronger among those with low social media literacy skills. This outcome contributes to theory and practice which was highlighted in the concluding aspect of this study.     

A blockchain-based trustworthy collaborative power trading scheme for 5G-enabled social internet of vehicles

Social Internet of Vehicles (SIoV) falls under the umbrella of social Internet of Things (IoT), where vehicles are socially connected to other vehicles and roadside units that can reliably share information and services with other social entities by leveraging the capabilities of 5G technology, which brings new opportunities and challenges, e.g., collaborative power trading can address the mileage anxiety of electric vehicles. However, it relies on a trusted central party for scheduling, which introduces performance bottlenecks and cannot be set up in a distributed network, in addition, the lack of transparency in state-of-the-art Vehicle-to-Vehicle (V2V) power trading schemes can introduce further trust issues. In this paper, we propose a blockchain-based trustworthy collaborative power trading scheme for 5G-enabled social vehicular networks that uses a distributed market mechanism to introduce trusted power trading and avoids the dependence on a centralized dispatch center. Based on the game theory, we design the pricing and trading matching mechanism for V2V power trading to obtain maximum social welfare. We use blockchain to record power trading data for trusted pricing and use smart contracts for transaction matching. The simulation results verify the effectiveness of the proposed scheme in improving social welfare and reducing the load on the grid.     

Social impacts of road traffic: perceptions and priorities of local residents

The assessment of the social impacts of road traffic is usually based on objective indicators or on expert judgement, without input from the affected communities. This paper considers the perceptions and priorities of local residents about traffic impacts and possible mitigation measures, using as a case study a rural area that will be affected by traffic associated with the construction of a nuclear power station. The study consisted of a qualitative phase followed by a stated preference survey. Econometric models were used to measure the relative priority of different impacts and mitigation measures. The most impactful aspects were noise, vibration and increased car or bus travel times. The most preferred measures were night-time restrictions to HGVs, parking restrictions and safety measures for pedestrians and cyclists. There were significant differences in preferences according to residence location, gender, employment status and household composition. The results provide information about aspects that tend to be aggregated in existing assessment frameworks, separating the reduction in the utility of some activities (like walking and driving) and the suppression of those activities.     

关于APP跨类别交叉推广的精准营销小数据设计研究

目的挖掘大学生群体的潜在需求,辅助企业进行交叉推广的精准营销,在信息筛选上以更有针对性的方式设计移动端产品。方法收集大学生群体使用手机超过6600个APP的小数据,运用统计学相关性原理对跨类别应用进行相关性分析。结论小数据分析发现大学生群体对社交类的兴趣偏好最强,其中女性更关注摄影与录像类。相关性方面,生活类、旅游类、美食佳饮类三者之间的相关性最高。交叉推广的方式上,健康健美类与导航类可以依附于摄影与录像类,音乐类和效率类可以依附于社交类进行辅助推广,而摄影与录像类和生活类可以相互推广,男性群体中的参考类和女性群体中的新闻类,均可和商务类以及图书类相互推广。可将兴趣偏好、相关性以及兴趣偏差纳入大学生群体的交叉推广中,进行信息筛选和设计。
