Corporate Career Presences on Social Network Sites: An Analysis of Hedonic and Utilitarian Value
Contribution & Benefit: Presents a structural equation model which describes what benefits job seekers derive from corporate career presences on social network sites.
Abstract » Due to the shortage of skilled workforce and the increasing usage of social network sites, companies increasingly apply social network sites to attract potential applicants. This paper explores how corporate career presences on network sites should be realized in order to attract potential applicants. Therefore, we tested the impact of seven individual characteristics (namely Appointments, Daily Working Routine, Jobs, Corporate News, Entertainment, Media Format, and Features) of these corporate career presences that we extracted by a comprehensive pre-study on users' perceived hedonic and utilitarian value of these presences on social network sites. Based on an online survey with 470 participants, the results reveal a highly significant impact of five characteristics that corporate career presences provide both a hedonic as well as a utilitarian value to the user.ACM
Finding and Assessing Social Media Information Sources in the Context of Journalism
Contribution & Benefit: Design and evaluation of a system for journalists to filter and assess the verity of sources found through social media, including eyewitness, user-archetype classifiers, and network and location cues.
Abstract » Social media is already a fixture for reporting for many journalists, especially around breaking news events where non-professionals may already be on the scene to share an eyewitness report, photo, or video of the event. At the same time, the huge amount of content posted in conjunction with such events serves as a challenge to finding interesting and trustworthy sources in the din of the stream. In this paper we develop and investigate new methods for filtering and assessing the verity of sources found through social media by journalists. We take a human centered design approach to developing a system, SRSR ("Seriously Rapid Source Review"), informed by journalistic practices and knowledge of information production in events. We then used the system, together with a realistic reporting scenario, to evaluate the filtering and visual cue features that we developed. Our evaluation offers insights into social media information sourcing practices and challenges, and highlights the role technology can play in the solution.ACM
Evaluation of the Uses and Benefits of a Social Business Platform
- Long Case Study
Contribution & Benefit: This case study evaluates how knowledge workers within a corporation use and benefit from using a social business platform and how different patterns of staff activities impact their experienced benefits.
Abstract » We evaluated an integrated social software platform, called Handshake, to determine individuals’ usage patterns and characterize Handshake’s business value. Our multi-step investigation included conducting 63 in-depth interviews, analyzing log data from 4600+ users, and administering an online survey. We found that both the level and type of participation affects whether users experience value. Active participants, for example, say that Handshake supports collaboration, strengthens social connections, fosters awareness of connections’ activities, and facilitates knowledge management. This case study captures an early snapshot of behavior that we anticipate will change and grow over time.
Sustainability of a College Social Network Site: Role of Autonomy, Engagement, and Relatedness
- Short Case Study
Contribution & Benefit: Case study describing successful factors of 10-year old college social network site. Suggestions to designers and administrators who want to create a sustainable online community.
Abstract » Increasingly, universities are trying, with limited success, to use social network sites (SNSs) as a way of retaining students. This study presents the case of Ewhaian.com, a 10-year old SNS for a large university in South Korea. Success factors are explained from the perspective of self-determination theory.
Understanding Experts' and Novices' Expertise Judgment of Twitter Users
Contribution & Benefit: Presents an empirical study to understand the differences between experts and novices in judging expertise of Twitter authors. Provides design guidelines for micro-blogger recommendation system.
Abstract » Judging topical expertise of micro-blogger is one of the key challenges for information seekers when deciding which information sources to follow. However, it is unclear how useful different types of information are for people to make expertise judgments and to what extent their background knowledge influences their judgments. This study explored differences between experts and novices in inferring expertise of Twitter users. In three conditions, participants rated the level of expertise of users after seeing (1) only the tweets, (2) only the contextual information including short biographical and user list information, and (3) both tweets and contextual information. Results indicated that, in general, contextual information provides more useful information for making expertise judgment of Twitter users than tweets. While the addition of tweets seems to make little difference, or even add nuances to novices� expertise judgment, experts� judgments were improved when both content and contextual information were presented.ACM
