Will they stay or will they go? How network properties of WebICs predict dropout rates of valuable Wikipedians

This paper contributes to our understanding of an increasingly prevalent work system, web-based internet communities (WebICs). We are particularly interested in how WebICs are governed given the fact how different they are compared to more classical forms of organization. We study the governance of a WebIC by studying the structure and dynamics of their edit network. Given the fact that the edit network is a relational structure, social network analysis is key to understanding these work systems. We demonstrate that characteristics of the edit network contribute to predicting the dropout hazard of valuable WebIC members. Since WebICs exist only thanks to the activity of their contributors, predicting drop-outs becomes crucial. The results show that reputation and controversy have different effects for different types of Wikipedians; i.e., an actor’s reputation decreases the dropout hazard of active Wikipedians, while participation on controversial pages decreases the dropout hazard of highly active Wikipedians.     

How climate change organizations utilize websites for public relations

This study is designed to examine climate change organizations (CCO)’s online public relations. It analyzes CCOs’ communicative efforts to build and maintain relationships with key stakeholders including media, donors, volunteers, and communities by using their websites and social networks. To accomplish this, a content analysis of 60 CCO websites was conducted. The result indicates that CCOs utilize websites primarily for media relations and fund raising purposes. The function of building and maintaining relationships with communities, current donors/volunteers was not actively utilized on CCOs’ websites. The interactivity of communication with stakeholders was somewhat limited in CCO's online communication activities.     

Are social networking sites a source of online harassment for teens? Evidence from survey data

Media reports on incidences of abuse on the internet, particularly among teenagers, are growing at an alarming rate causing much concern among parents of teenagers and prompting legislations aimed at regulating internet use among teenagers. Social networking sites (SNS) have been criticized for serving as a breeding ground for cyber-bullying and harassment by strangers. However, there is a lack of serious research studies that explicitly identify factors that make teenagers prone to internet abuse, and study whether it is SNS that is causing this recent rise in online abuse or is it something else. This study attempts to identify the key factors associated with cyber-bullying and online harassment of teenagers in the United States using the 2006 round of Pew Internet™ American Life Survey that is uniquely suited for this study. Results fail to corroborate the claim that having social networking site memberships is a strong predictor of online abuse of teenagers. Instead this study finds that demographic and behavioral characteristics of teenagers are stronger predictors of online abuse.     

A survey of social media use, motivation and leadership among public relations practitioners

This study investigates the relationship between motivation, leadership and social media use among a sample of public relations practitioners who recently had begun using Twitter to follow Universal Accreditation Board (UAB)-affiliated organizations. A majority of the survey respondents were classified as “everyday users.” A series of Twitter leadership indicators correlated positively with internal motivation and correlated negatively with amotivation. Several word-of-mouth variables also were investigated with regard to motivation.     

Meshworked reputation: Publicists’ views on the reputational impacts of online communication

This paper discusses the conceptual and empirical connections between an organization's reputation management and online communication. The paper develops a theory driven model of the structural dimensions of reputation and analyzes organizational communication professionals’ views on the potential that online communication has for reputation management. The survey data showed that online communication was perceived to have positive impacts on the structure and advantages of reputation, and that these two aspects would seem to be strongly dependent on each other. Thus, online communication can be used to influence the assessments made by stakeholders about an organization's products and services, corporate responsibility, success, its ability to change and develop, and its public image. In addition, online communication can generate reputational advantages by strengthening stakeholder relationships and building social capital for the organization.     

The Relationship between Adult Students' Instructional Technology Competency and Self-Directed Learning Ability in an Online Course

The main purpose of this research was to examine the relationship between adult students' self-directed learning (SDL) ability and instructional technology (IT) competency in an online course. The study also investigated motivation and learning strategies that the students used to learn IT. The research involved surveying 198 continuing education professionals who took online courses at a large Midwest state university. The results indicate a statistically significant positive correlation between SDL ability and IT competency in students with above average SDL ability. The results also indicate that motivation is an important factor for learning technology in an online course regardless of the students' SDL ability. Additionally, the results show that students with higher level of SDL ability are likely to exhibit higher level of self-efficacy for learning and performance, and higher level of effort regulation.

MAKING THE CASE ONLINE: HARVARD BUSINESS SCHOOL MULTIMEDIA

New media technologies provide opportunities to expand academic curriculum offerings and enhance student learning. Yet web-based and online learning tools should not be just repurposed text and information, or videotaped faculty lectures. Instead, the web calls for the inclusion of sound, text and visuals for learning tools that provide a media-rich environment. This allows faculty to create multidimensional experiences that cater to different learning styles and provide opportunities for problem solving. Drawing on my production experiences at HBS, as well as my own experience teaching visual anthropology and creating films, videos, photographs and web products, I discuss the teaching opportunities that new technologies and media can provide.
