TOOR: A Novel Product Title Optimization Method Based on Online Reviews in E-commerce

Titles of online products play an important role in attracting consumers and promoting product sales in e-commerce. However, current online product titles only cover basic features and cannot reflect the preferences of consumers exactly. To address this problem, this research proposed an online title optimization method based on the analysis of online reviews, which is called TOOR (Title Optimization based on Online Reviews). In this research, we analyzed and compared product features extracted from online product titles and online reviews from the point of view of consumers and applied features extracted from reviews to title optimization. In order to verify the effectiveness of the proposed method, two experiments were conducted in this paper, selecting four typical smartphones as experiment samples and Taobao.com as the data resources. The experimental results indicated that features extracted from online reviews can better reflect the consumers’ concern, and the titles optimized by the TOOR method are more appealing to consumers and have higher click-through rates.     

Am I intruding? Developing a conceptualisation of advertising intrusiveness

This study develops a conceptual framework of advertising intrusiveness that extends previous research on the topic by examining both drivers and consequences. To achieve this, the work draws on in-depth interviews with 29 adult consumers who report experiencing intrusive advertising in their daily lives. Three drivers of advertising intrusiveness are identified – temporal disruption, visual disruption and flow disruption – along with three consequences – emotional response, behavioural response and cognitive response. From these drivers and consequences, a conceptual framework of advertising intrusiveness is developed based on ideas about psychological reactance. Based on this framework it is proposed that, while all advertisements might ultimately be perceived as intrusive, an advertisement’s characteristics, which are the identified subcomponents of the drivers of intrusiveness, exacerbate the resultant consequences.     

一种基于无线电环境地图的路由优化机制

设计认知无线网络路由算法时,需要兼顾主用户保护与路由性能两个方面。为了提高认知无线网络中次用户之间路由的端到端性能,提出了基于无线电环境地图的路由优化机制,该机制中无线电环境地图能够为次用户提供主用户保护有关的无线电环境数据。首先,无线电环境地图根据次用户的数据请求将各授权频段的可用概率与功率控制相关信息反馈到该次用户;其次,次用户可以计算出与上一跳次用户之间的链路稳定性以及传输时延;最后,目的次用户通过计算每条路由的端到端吞吐量的期望值,然后选取期望值最大的一条路由。仿真结果表明,该路由机制在平均分组投递率、平均端到端吞吐量、平均端到端时延方面均优于对比路由算法。     

Self-Regulation for Online Behavioral Advertising (OBA): Analysis of OBA Notices

This study assessed how and to what extent self-regulation of online behavioral advertising (OBA) is executed on participating companies' websites. Based on the principles of OBA, as outlined by the Digital Advertising Alliance and Federal Trade Commission, we analyzed the format of OBA notices, explanation of OBA notices, opt-out options, transparency, and use of unacceptable notices. A series of content analyses was done in the years 2013 and 2015. Our results indicated slight improvements over the years, but the specific details of the implementation continued to fall short of the standards. In terms of accessibility and visibility, many websites demonstrated problematic presentations or lack of the components necessary to increase consumers' understanding and control over the practice of OBA.     

The impact of online financial disclosure and donations in nonprofits

Decreased public confidence and trust in the nonprofit sector has fueled increased calls for transparency. In response, federal regulators and watchdog organizations have recommended that nonprofits voluntarily disclose their financial information on their own public websites. Despite the potential benefits of enhanced public confidence and trust, improved donor decision making, and increased donations, many nonprofit organizations have not adopted the recommended disclosure practices. We investigate the disclosure practices of 3,217 nonprofits and find that voluntary web disclosure of the IRS Form 990 is strongly correlated to donations, independent of other variables such as age, size, and fundraising expenditures. Further, fundraising is also clearly related to the performance indicators shown in the 990 disclosures, particularly the program ratio of program expenditures to total expenditures. This is true on a general level and when specifically compared to other nonprofits within particular sectors. As a result, nonprofits should seriously consider voluntarily posting their Form 990 results on their websites when it reflects favorably and strive to improve their financial performance if online disclosure would reflect poorly on the organization.
