This work empirically evaluates the effectiveness of the novel ontology-based access-control mechanism and the common password-protected access-control mechanism for social blogs. The paper aims to discuss these issues.

The ontology-based access-control scheme is designed to fit two characteristics of blog activities: social relationships and tags. A laboratory experiment is conducted to assess the perceived privacy benefit and perceived ease of use of the two mechanisms.

Analytical results indicate that, with the ontology-based access-control scheme, users perceive more privacy benefit than with the password-protected access-control scheme. The perceived ease of use with the ontology-based and password-protected access-control systems did not differ significantly.

Cross-boundary collaborations need an appropriate approach to control communication access. Further study is required to evaluate the ontology-based access-control scheme applied in cross-organizational and cross-departmental collaborations.

From a knowledge management perspective, blogs can store personal and organizational knowledge and experiences. The ontology-based access-control scheme encourages knowledge sharing for appropriate persons.

The new ontology-based access-control mechanism can help online users keep secrets from selected people to gain more privacy benefits than the existing password-protected access-control mechanism.

Check-in based advertising is growing dramatically as the popularity of social media increases. The purpose of this paper is to explore which social cues are appropriate for check-in based advertising in social media based on media richness theory and how content effectiveness affects content generation intention based on achievement motivation theory.

A laboratory experiment was performed to evaluate the effects of social cue strategies on content effectiveness of attitude toward the ad and self-efficacy on recall. The influence of effectiveness on content generation intention are also measured in the experiment.

The results of a laboratory experiment indicated that a strategy of using plentiful social cues has high effectiveness as measured by the concept of attitude toward the ad. Content effectiveness measured by attitude toward the ad and self-efficacy on recall can directly affect user intentions to generating check-in based advertisements.

Although check-in based advertising is driven by the customers themselves rather than by the company, companies can encourage their customers to follow an appropriate check-in content generation strategy to improve effectiveness.

The findings of this study provide useful information for designing the content of social media designed to facilitate the promotion of products and companies in online marketing.

In theoretical contribution, this study integrates media richness theory and achievement motivation theory to explore how users intent to generate check-in advertising according to social cues effectiveness.

This paper aims to manage access control tasks to satisfy the user privacy needs of online information resources according to social relations and tags.

The study proposes a method for access control management in the online social context. The proposed method includes the access control policy management process, metadata of access control policies, the data of ontologies, tags, and social relations, and conflict detection rules.

Online information sharing and hiding, which needs to consider social relations and mentioned topics, is a unique context and needs a novel access control mechanism. Ontologies are powerful and expressive enough to identify conflicts in access control policies. The paper provides a method using ontologies to control the access control activities based on social relations and tags on web content. The effectiveness of the method's conflict detection rules is validated through several scenarios.

To make the proposed method suitable for widespread usage, further work is required to develop an access control policy specification and conflict detection tool. The proposed method introduces relatively novel usage scenarios, which consider social relationships, and tags compared with existing access control methods for online information sharing.

The proposed access control mechanism can be integrated into existing web sites. Online users can use this method to share information more easily than at present.

The method enables flexible access control in social contexts and handles unavoidable conflicts. It also opens the way to new access control scenarios in online social activities. The method can be used to keep secrets hidden from selected people.

Conversations surrounding gender are sweeping the globe as the voices and lived experiences of people are being heard and shared at unprecedented rates. Discourses about gender in advertising are embedded in cultural narratives and legitimatized by a broad system of institutional structures and actors, at both macro and micro/consumer levels. This study aims to explore how consumers (one type of institutional actor) engage in legitimizing/delegitimizing messages of gender in the marketplace.

This research draws on a qualitative approach, specifically the use of in-depth interviews with men across three global contexts.

This research identifies the ways in which men engage in (de)legitimizing messages of masculinity in advertising such as reiteration, reframing, ascribing to alternate logics and prioritizing personal norms.

Across three contexts, this research theorizes the (de)legitimization of gender ideals in advertising and situates consumer narratives within broader institutional forces, providing a holistic understanding of the phenomenon.

Understanding the ways in which individuals either accept or reject gendered ideals in media aids advertising and marketing professionals in tailoring messages that resonate with audiences.

Understanding how individuals negotiate their gender and the messages they deem as legitimate are crucial to understanding gender issues related to consumer welfare and public policy.

While research has examined advertising practitioners’ views regarding gender from an institutional perspective, research on how consumers construct and maintain the legitimacy of gendered messages in the marketplace is scarce. This research theorizes and illustrates the (de)legitimization of gender ideals across three contexts.
