This study examined factors (e.g., ad values and social networking advertising characteristics) influencing consumers' attitudes and behavioural intention towards three types of social networking advertising (SNA) on Facebook – home page ad, social impression ad, and organic impression ad. Findings demonstrate that peer influence had the most significant impacts on attitude and behavioural intention across all types of SNA. The significant interaction term of invasiveness and privacy concern indicates that both attitude and behavioural intention were diminished, particularly when perceived invasiveness and privacy concern were high simultaneously. In addition, results suggest that attitudes towards the ad played a mediating role between SNA characteristics and behavioural intention. Lastly, among the types of SNA, consumers preferred organic impression ads that featured friends' names on their newsfeed more than paid ads located on the sidebar of their Facebook pages.  相似文献

近年来,在互联网领域出现的"人肉搜索"现象,已经受到人们越来越多的关注。"人肉搜索"作为一种信息搜索工具,结合了现代网络技术与传统检索的优点。它从虚拟社区向现实世界的这次跳跃,得到的并不仅仅是掌声,还有质疑甚至恐俱。一方面,它具有一定的社会舆论监督意义;另一方面,它往往会涉及侵害个人的隐私权以及侵犯公民的其他正当权益。因此,在保护公民合法权益的同时,发挥"人肉搜索"的正面作用,并对其加以理性约束,具有重要的理论和现实意义。  相似文献

The Economist recently declared that digital information has overtaken oil as the world’s most valuable commodity. Big data technology is inherently global and borderless, yet little international consensus exists over what standards should govern its use. One source of global standards benefitting from considerable international consensus might be used to fill the gap: international human rights law. This article considers the extent to which international human rights law operates as a legal or ethical constraint on global commercial use of big data technologies. By providing clear baseline standards that apply worldwide, human rights can help shape cultural norms—implemented as ethical practices and global policies and procedures—about what businesses should do with their information technologies. In this way, human rights could play a broad and important role in shaping business thinking about the proper handling of this increasingly valuable commodity in the modern global society.  相似文献

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.  相似文献

To test a theoretical model, this study explores the effect of anxiety, trust, personality, and perceived benefits on the disclosure of personal information online. An online survey conducted among participants in the United States (n = 248, age range: 20–82 years) examined attitudes toward disclosing personal data online. Specifically, the study researches the impact of anxiety disclosing personal data, trust (both in the Internet and in institutions), the Big Five personality traits, and four sets of perceived shopping benefits (opportunity, bargain, purchase, and expected privacy benefits) in e-commerce disclosure and their role as antecedents for adoption and use of e-commerce. The study aligns with existing trust literature and corroborates other findings on how perceived purchase benefits impact individuals’ attitudes toward disclosing personal data online. The data suggest that both trust in the Internet and trust in institutions positively influence attitude toward disclosing personal data online. Perceived purchase benefits were also significant positive predictors for attitude toward disclosing personal data online. Furthermore, personality dimensions can affect attitude toward disclosing: the more neurotic a person is, the more negative their attitude is about disclosing personal data online. The study underscores that consumers have a responsibility to educate themselves about online disclosure and marketing practices, and about how to protect their online privacy. Most importantly, fostering trust, reducing anxiety, and promoting benefits are essential to the future of e-commerce. Implications for theory, consumers, marketing practice, and public policy are also discussed.  相似文献

Tourism to the Canary Islands is centred around competitively priced holidays focused on the sun and beach mass tourism experience. A restructure of the islands' wine industry offers opportunities for developing new tourism alternatives based on gourmet products and traditional landscapes. This paper examines the potential of wine tourism from winery operators' perspectives. Challenges to overcome in the development of a successful sustainable local wine tourism industry include the need for expansion of the destination image to reflect the region's wine‐making history and scenic qualities; a shift towards independent high‐yield travellers; and reintroducing local produce in the mass tourism product.

We analyzed the determinants of acceptance of genetically modified food (GMF) by using the probit model. In this study, we found that around 41% of the students are willing to buy GMF, and acceptance of GMF is less in female respondents than male respondents. The findings indicate that in India, benefit perception of GMF outweighed the risk perception. We also found that respondents’ trust in international organizations for truthful information has a positive and significant influence on acceptance of GMF.  相似文献

This paper presents a conditional role-involved purpose-based access control (CPAC) model, where users dynamically activate conditional roles in accordance with the context attributes. Based on conditional role, access permissions are assigned that represent what can be accessed for what purpose to roles under certain conditions. On the other hand, conditional purpose is applied along with allowed purpose and prohibited purpose in the model. It allows users using some data for certain purpose with conditions (for instance, Tony agrees that his income information can be used for marketing purposes by removing his name). The structure of a CPAC model is defined and investigated. Access purpose is verified in a dynamic behavior, based on user attributes, context attributes, and authorization policies. Intended purposes are dynamically associated with the requested data object during the access decision. An algorithm is developed to achieve the compliance computation between access purposes and intended purposes and is illustrated with role-based access control (RBAC). Access purpose authorization and authentication in the model are studied with the hierarchical purpose structure. The model separates authorization of access purpose from access decision that improves the flexibility of private data control.  相似文献

We examine the impact of the global financial crisis (GFC) on auditor behaviour in Australia. Using a sample of listed companies, we examine whether the GFC impacted the propensity of auditors to issue going concern modifications and increased audit effort as reflected in audit fees and audit reporting lag. Controlling for client characteristics, we find an increase in the propensity to issue going concern opinions during the period 2008–2009 compared with the period 2005–2007 and that Big N auditors responded to the GFC earlier than non‐Big N auditors. In relation to audit effort, we find evidence of increased audit fees during the period 2008–2009 compared with the period 2005–2007. There is, however, no evidence of increased audit reporting lags during the GFC.  相似文献
