Virtual reality has the potential to enhance a variety of real-world training and entertainment applications by creating the illusion that a user of virtual reality is physically present inside the digitally created environment. However, the use of tactile feedback to convey information about this environment is often lacking in VR applications. New methods for inducing a degree of tactile feedback in users are described, which induced the illusion of a tactile experience, referred to as pseudo-tactile feedback. These methods utilised shared properties between audio and tactile feedback that can be crossmodally mapped between the two modalities in the design of a virtual reality prototype for a qualitative usability study in order to test the effectiveness and underlying causes of such feedback in the total absence of any real-world tactile feedback. Results show that participants required believable audio stimuli that they could conceive as real-world textures as well a sense of hand-ownership to suspend disbelief and construct an internally consistent mental model of the virtual environment. This allowed them to conceive believable tactile sensations that result from interaction with virtual objects inside this environment. [ABSTRACT FROM AUTHOR]

For the past twenty years phrases such as "stable information needs", "unstable information needs" or "information needs changing over time" are found in many contributions to information science. At first view these concepts seem to be easy and clearly understandable. However, after some considerations different questions arise: For which types of information need do we see that these needs are changing over time -- for all types, or only for certain types? How do information needs relate to changes in the world, or to changes in the human understanding of the world? We will show that "information need changing over time" is a very complex concept and only understandable if we distinguish between changes in the world, situation/context, user, types of information need and interpretation of data. Clarity of writing is essential in scientific writing and authors using the concept "information needs changing over time" or similar phrases should clearly define what they mean by the phrases to ensure that no ambiguity exists when readers interpret their writings.

Library leaders may not be fully equipped to deal with the demands and rigours of the digital age and its consumers. The advent of the internet, search engines and social media require a paradigm shift in the development of these leaders. Whilst much has been written about the required competencies, there seems to be no clear guiding principle on how the development should take place. The authors propose that the development of library leaders is a process, best illustrated through movement through Drotter's Leadership Pipeline. The importance of thinking preferences, based on Herrmann's Whole Brain Model, is highlighted and it is shown how these often clog development through this Pipeline. Utilising data from the Herrmann Brain Dominance Instrument (HBDI) assessments of the 120 participants in six of the Centre for African Library Leadership (CALL) development programmes, the authors show how the thinking preferences of these library leaders could enable or detract from their readiness to develop the appropriate competencies in the digital age. Recommendations are made on how best to overcome this to prepare library leaders to deal with the requirements of the digital age consumer. [ABSTRACT FROM AUTHOR]

The University of Pretoria introduced a compulsory Information Literacy module to address the need for delivering motivated knowledgeable employees that embrace information and have the skills to find, select and use relevant information accurately, efficiently and effectively in an explosive information age. Low class attendance, an indication of unmotivated students, as well as the limited scholarly application of information literacy skills in consecutive academic years of study have been identified as possible barriers to the application of the desired skills. A collaborative action research project based on Whole Brain principles was introduced to motivate learners through innovative learning material in the module. A deeper understanding of the role of thinking preferences and thinking avoidances is essential in selecting a team that is responsible for the planning, design, development and delivery of learning opportunities and material. This article discusses the Whole Brain Model® as a mental model that underpins the successful collaboration of multidisciplinary teams and enhances innovative curriculum design that addresses alternative approaches to the teaching of Information Literacy.

During 2000–2004 a project was undertaken to create a comprehensive and informative inventory of South African public and community libraries, the Public and Community libraries Inventory of South Africa (PaCLISA). The project was executed in two phases, initially under the guidance of the Libraries Working Group of the Print Industries Cluster Council (PICC). Phase 1 was carried out during 2000–2001 and funded by The Carnegie Corporation of New York and the Foundation for library and Information Service Development (FLISD), through the National Library of South Africa. The Centre for Geo-Information Science of the University of Pretoria was contracted to carry out the project. In light of the response to Phase 1, a consultative process was followed to redesign the inventory questionnaire, after which Phase 2 was carried out during 2003–2004 as a project of the Department of Information Science and the Centre for Geo-Information Science of the University of Pretoria. Although the project was not an unqualified success, it was a valuable learning experience. The article provides an overview of the project with special emphasis on the lessons that have been learned and what these imply for future efforts to inventorise South Africa's public libraries.
