Social networking and Web 2.0 in information literacy

This paper discusses free online and Internet tools that can be adapted by librarians for use with library instruction and information literacy training, with a focus on social media and Web 2.0 technologies, including social networking websites Facebook and Twitter, blogs, RSS, wikis, and video sharing. Many students already use these technologies and are readily engaged with the library when the technologies are incorporated into library websites and classes. There are challenges in using these technologies, especially in countries with oppressive governments. This paper is based, in part, on a presentation the authors gave at the UNESCO Training the Trainers in Information Literacy Workshop at the Bibliotheca Alexandrina in Alexandria, Egypt in November 2008.

Renewed roles for librarians in problem-based learning in the medical curriculum

Problem-based learning (PBL) is a teaching-learning process or method of instruction that is widely used in medical education curricula. Librarians play important roles as facilitators for PBL as well as guides for information resources. Involvement in PBL activities presents unique opportunities to incorporate library resources and instruction into the medical curriculum. This article reviews the problem-based learning method within the conceptual framework of the learning theory of constructivism. It describes how a medical librarian at a U.S. medical school used emerging technologies to facilitate PBL small group case discussions, guide students to quality information resources, and enhance the learning environment for the PBL process.

Training for the Unthinkable: Examining Message Characteristics on Motivations to Engage in an Active-Shooter Response Video

Campus safety is becoming an increasing concern for academic institutions due to numerous recent tragedies. To prepare students, staff, and faculty for these events, schools are beginning to use active shooter response training videos such as Run, Hide, Fight—a 5-minute video created by the U.S. Department of Homeland Security. Framed in protection motivation theory, this study employs a 3 x 2 factorial design to test the influence of message medium (email, text, or tweet) and frame (direct or fear-based message) on students' completion of the safety training video. The findings suggest that the combination of message frame and message medium influence training completion. Additionally, the video itself led to a significant increase in participants’ self-efficacy, safety knowledge, and campus safety salience.     

Examining the application of Web 2.0 in medical-related organisations

Objectives: This study surveyed Web 2.0 application in three types of selected health or medical‐related organisations such as university medical libraries, hospitals and non‐profit medical‐related organisations. Methods: Thirty organisations participated in an online survey on the perceived purposes, benefits and difficulties in using Web 2.0. A phone interview was further conducted with eight organisations (26.7%) to collect information on the use of Web 2.0. Data were analysed using both quantitative and qualitative approaches. Results: Results showed that knowledge and information sharing and the provision of a better communication platform were rated as the main purposes of using Web 2.0. Time constraints and low staff engagement were the most highly rated difficulties. In addition, most participants found Web 2.0 to be beneficial to their organisations. Conclusions: Medical‐related organisations that adopted Web 2.0 technologies have found them useful, with benefits outweighing the difficulties in the long run. The implications of this study are discussed to help medical‐related organisations make decisions regarding the use of Web 2.0 technologies.

Devising Video Distribution Strategies via the Internet: Focusing on Economic Properties of Video Products

This article tries to link economic properties of video products to strategies that can be used by Internet-based video distributors. First, this study suggests 4 economic properties of video products: video as an experience good, returns to scale, video as a public good, and interdependency of willingness to pay. Second, based on economic attributes, this study synthesizes several strategies. Finally, this article uses a case study to compare theoretical strategies to actual strategies used by 2 Internet-based movie distributors. As a result of this study, we found that there are several possible strategies that are not yet being used in practice. It is expected that as the market becomes more mature through the development of technologies (e.g., digital rights management), more strategies will be adopted by online video distributors.     

The digital library of Iberoamerica and the Caribbean: humanizing technological resources

In the last two decades, the University of Colima has worked out a very interesting project for information technologies development through its Coordination for Information Technologies (CIT) program. This has provided years of experience in the application of technologies for the academic community. After its designation as a UNESCO Regional Center, our university developed a very ambitious education and research plan that was submitted to one of UNESCO's educational programs. This project was approved as the “UNESCO Chair on New Information Technologies,” and it started working successfully with the “Diploma Course on Digital Libraries” 2 years ago.

The Diploma Course is part of the action taken toward the creation of a Great Iberoamerican and the Caribbean Digital Library. Today 144 trainers from 36 national libraries in Latin America and the Caribbean state members are receiving training courses based on the UNESCO methodology, which is comprised of the registration of digital objects, adherence to standards for audio and video digitization, and development of an international open-source software for information management.     

Yesterday,Today, Tomorrow

The rapid growth of computer technologies to supplement and eventually supplant print as the dominany medium for the provision of government reference information has profound implications for the role of government and the private sector in the creation, enhancement, and dissemination of these products and services. The reluctance of the federal government to provide full and free access to information in electronic formats precludes society's attainment of the concept of equity that is a touchstone of democracy. A way most certain to insure public access would acknowledge a First Amendment penumbra embodying the right to be informed, but this would require a Supreme Court ruling pursuant to a justiciable controversy. Based upon current official policies, the future holds little promise of an equitable diffusion of government information in non-print formats through the depository library system or related statutory mandates.     

Evidence-Based Practice: a new paradigm brings new opportunities for health sciences librarians

It is questionable whether the Evidence-Based Health Care model, whereby end users appraise all potentially pertinent information, is sustainable. A shift to an Evidence-Based Practice model, featuring a new medical knowledge base infrastructure facilitating rapid translation of clinical research into practice should be embraced. This shift would offer new opportunities for health sciences librarians. In this article, the authors: (1) review milestones in the evolution of the health sciences knowledge base; (2) review the evolution of the Evidence- Based Health Care/Practice model of health information utilization; and (3) discuss the significance and implications for health sciences librarians of trends towards an increasingly digital health information environment. The authors suggest new roles for health sciences librarians: partnering to integrate advanced information management technologies into the clinical enterprise and integration into the processes for developing these technologies.

Mediacy: Knowledge and Skills to Navigate the Information Highway

The abilities to explore information space, discover, learn, find, manage, organize, evaluate, create, use, and preserve information are complex and they vary depending upon the type of information and the format or medium in which it is presented. The knowledge and skills for print media are different from those for full motion video. The knowledge includes recognizing different needs for information; understanding and using different measures of value; and understanding ethical issues — all within multicultural and diverse environments, traditions, and contents. Skills include those related to retrieving, managing, organizing, using, preserving, and communicating information. This presentation explores these complex abilities, describing earlier work, and addresses pertinent issues.
