Ephemerality in Social Media: Unpacking the Personal and Social Characteristics of Time Limit Users on WeChat Moments

Social media platforms increasingly give users the option of ephemerality through settings that delete or hide posted content after a set period of time. Many individuals apply these settings to manage their posting history and, in turn, reduce concerns about self-presentation. Despite the growing popularity of this feature, few studies have empirically explored it. This study examines the Time Limit setting on WeChat Moments as an example and investigates how users using the Time Limit setting differ from nonusers in terms of personal characteristics (demographics, personality traits, psychological factors, and previous behavioral patterns) and social characteristics (audience size and audience diversity). Compared with nonusers, users using Time Limit setting scored significantly higher on posting frequency and privacy setting use and scored significantly lower on audience size. We also examine how personal and social characteristics vary between user groups with different degrees of ephemerality (i.e., low, medium, or high). Our findings show that users using the Time Limit setting who scored higher on measures of life changes, self-monitoring, posting frequency, and audience size and lower on perceived stress were more likely to opt for the low (i.e., 6months) rather than the medium (i.e., 1month) or high (i.e., 3days) degree of ephemerality. Our work contributes to the understanding of ephemerality settings on social media platforms and provides insights that help practitioners design more effective platforms.

Assisting humans in privacy management: an agent-based approach

Image sharing is a service offered by many online social networks. In order to preserve privacy of images, users need to think through and specify a privacy setting for each image that they upload. This is difficult for two main reasons: first, research shows that many times users do not know their own privacy preferences, but only become aware of them over time. Second, even when users know their privacy preferences, editing these privacy settings is cumbersome and requires too much effort, interfering with the quick sharing behavior expected on an online social network. Accordingly, this paper proposes a privacy recommendation model for images using tags and an agent that implements this, namely pelte. Each user agent makes use of the privacy settings that its user have set for previous images to predict automatically the privacy setting for an image that is uploaded to be shared. When in doubt, the agent analyzes the sharing behavior of other users in the user’s network to be able to recommend to its user about what should be considered as private. Contrary to existing approaches that assume all the images are available to a centralized model, pelte is compatible to distributed environments since each agent accesses only the privacy settings of the images that the agent owner has shared or those that have been shared with the user. Our simulations on a real-life dataset shows that pelte can accurately predict privacy settings even when a user has shared a few images with others, the images have only a few tags or the user’s friends have varying privacy preferences.

PSEUDONYM AND PERSONA MANAGEMENT IN PSYCHOANALISYS APPROACH AMONG J-POP FANS IN SOCIAL MEDIA

ABSTRACT The development of communication technology makes a new form of persona management strategies. Facebook is one of social media, which can make the borders of public persona and private persona to be blurred and invisible. This research aims to explore the persona management in pseudonym practice through psychoanalysis approach by Japanese popular culture’s fans on Facebook by separating their personas in RL (Real Life) account and fannish account. This research is a qualitative research and using constructivism paradigm. Data collection was obtained by unstructured interviews submitted to two Facebook users. The data is then processed and analyzed interpretively. Study found that the main motive of fans using pseudonimity in social media is to avoid the stereotype threats from their real-life society. Virtual ethnography methods are also used which depart from virtual participatory observation methods for pseudonym accounts and participant RL accounts Study also found that there’s a new form of persona management strategies by using social media’s technology features such as blocking, unfriend-ing, and using privacy setting feature, and the other strategies. So, their persona is public yet private towards some audience. Keywords; fandom, persona, pseudonym, fans, popular culture. ABSTRAK Perkembangan teknologi komunikasi menciptakan bentuk baru dari strategi manajemen persona.

A Model for Predicting Human Depression using Machine Learning Algorithm

In recent days people share their images in many social media and also they are not certain about the privacy. This leads to many issues. In light of these incidents, a tool is needed for providing access control method during user’s file sharing. To do that, Adaptive Privacy Policy Prediction (A3P) system is proposed for setting the privacy parameters to their images. The image data, user’s social context and their meta data are used in the privacy setting preferences. The author proposed a two-stage framework for determining and setting the existing privacy policy in accordance to the user’s history over the website. The proposed solution depends on the image categories and the social features of the user. Also, it depends on the user’s privacy data and the relevant features. From the experimental and simulation results it is proved that the privacy preservation is one of the important task in internet applications.

What drives self-disclosure in mobile payment applications? The effect of privacy assurance approaches, network externality, and technology complementarity

Purpose Drawing on the control agency theory and the network effect theory, the purpose of this paper is to examine the effect of privacy assurance approaches, network externality and technology complementarity on consumers’ self-disclosure in mobile payment (MP) applications. The authors identify four types of privacy assurance approaches: perceived effectiveness of privacy setting, perceived effectiveness of privacy policy, perceived effectiveness of industry self-regulation and perceived effectiveness of government legislation. The research model considers how these privacy assurance approaches influence privacy concerns and consumers’ self-disclosure in MP applications under boundary conditions of network externality and technology complementarity. Design/methodology/approach An online survey with 647 sample users was conducted to empirically validate the model. The target respondents were current consumers of a popular MP application. The empirical data were analyzed by a structural equation modeling approach. Findings The empirical results reveal several major findings. First, privacy assurance approaches can effectively decrease privacy concerns, which ultimately formulates consumers’ self-disclosure in MP applications. Second, network externality and technology complementarity weaken the effect of perceived effectiveness of privacy setting on privacy concerns. Third, network externality and technology complementarity strengthen the relationship between perceived effectiveness of government legislation and privacy concerns, while they have non-significant interaction effect with perceived effectiveness of privacy policy and industry self-regulation on privacy concerns. Practical implications MP providers and stakeholders can harness the efficacy of privacy assurance approaches in alleviating privacy concerns and promoting consumers’ self-disclosure in MP applications. Originality/value The authors’ work contributes to the information privacy literature by identifying effective privacy assurance approaches in promoting consumers’ self-disclosure in MP applications, and by highlighting boundary conditions of these privacy assurance approaches.
