What are analog bulletin boards used for today? Analysing media uses, intermediality and technology affordances in Swedish bulletin board messages using a citizen science approach
Analog bulletin boards are omnipresent in Swedish urban areas, yet little systematic knowledge about this communication medium exists. In the shadow of the rapid emergence of digital media the analog bulletin board has received less attention than its digital successors, many of them having incorporated similar functionality with novel technical solutions. In this study we used a citizen science method to collect 1167 messages from bulletin boards around Sweden aided by school children and teachers, with the purpose of shedding new light on what is communicated on the boards, by whom, using what types of technologies and in what way the messages refer to other media. Results show that the most common messages are invitations to events, such as concerts, lectures and sports events, followed by buy-and-sell ads for goods and services. The most frequent sender is an association, for example NGOs, sports associations or religious communities. Almost half of the sampled messages were professionally printed, about forty per cent were made by home printers. Only six per cent of the messages were handwritten, almost exclusively by private persons as senders. Moreover, we show how the analog bulletin board has adapted to recent changes in media technology-a media landscape which is saturated with electronic- and mobile media. Further, the bulletin board still holds a firm place in a media ecology where local communication is in demand, and exists in parallel with electronic media. Close to forty percent of the messages contained hyperlinks to web pages and we found (and removed for anonymization purposes) more than six hundred phone numbers from the dataset.

A case for location based contact tracing
We present an evaluation of the effectiveness of manual contact tracing compared to bulletin board contact tracing. Classical contact tracing relies on reaching individuals who have been in proximity to an infectious person. A bulletin board approach focuses on identifying locations visited by an infectious person, and then contacting those who were at those locations. We present results comparing their effects on the overall reproductive number as well as the incidence and prevalence of disease. We evaluate them by building a new agent based simulation (ABS) model using the Susceptible Exposed Infectious and Recovered (SEIR) framework for disease spread. We conduct simulation experiments to quantify the effectiveness of these two models of contact tracing by calibrating the model to be compatible with SARS-CoV-2. We find that bulletin board contact tracing gives comparable results in terms of the reproductive number, duration, prevalence and incidence but is less resource intensive, easier to implement and offers a wider range of privacy options. Our experiments show that location-based bulletin board contact tracing can improve manual contact tracing.

Non-public and public online community participation: Needs, attitudes and behavior
Nonpublic participation within an online community, often called lurking, occurs when an individual joins a community, but does not post. This study examines the nature of lurking, why people lurk and the differences in attitudes between lurkers and posters. The results indicate significant differences between people who lurk and those who post in an online community. We conclude that when people lurk they are observing, which in no way is a negative behavior. This introverted or passive behavior affects lurkers' attitudes about the benefits of the community, their expectations, and opinions of themselves and others who lurk. In general lurkers are less optimistic and less positive than those who post. [PUBLICATION ABSTRACT]

Effects of Mobile Instant Messaging on Collaborative Learning Processes and Outcomes: The Case of South Korea
The purpose of this paper was to investigate the effects of mobile instant messaging on collaborative learning processes and outcomes. The collaborative processes were measured in terms of different types of interactions. We measured the outcomes of the collaborations through both the students' taskwork and their teamwork. The collaborative learning processes and outcomes in the Mobile Instant Messaging group (Mobile IM) were also compared with the Personal Computer-based Instant Messaging group (PC IM) and the Bulletin Board System group (BBS). A total of 48 students participated in this study, and the main results show that more cognitive and metacognitive interactions were found in the BBS group while social and affective interactions were the major types of interactions in the Mobile IM group and the PC IM group. As a result of the collaborative learning outcomes, the Mobile IM group shows better teamwork than the other two groups. However, better taskwork was found in the BBS group and the PC IM group rather than the Mobile IM group. Finally, the researchers discuss the implications of this study from the perspective of the educational potential of mobile learning.

Innovations in Research with Medically Fragile Populations: Using Bulletin Board Focus Groups
A new group of medically fragile young adults are graduating from pediatric palliative care programs with limited expectations to live beyond early adulthood, and no comparable adult services to support their complex needs. Accessing this population is difficult because of the complexity of their conditions, the extensive personal and equipment supports that limit feasibility for travel, and divergent communication abilities. Therefore, we undertook a descriptive case study using an asynchronous modification of an online focus group, a bulletin board focus group (BBFG). The greatest strengths of the BBFG are the appeal of this methodology for young adults and the multi day focus group becomes both a community and an intervention. An important limitation of this method was participant follow through on discussion threads. This BBFG provided rich and varied types of data, and very positive participant experiences.
