Dr Anamika Megwalu, an assessment and engineering librarian at San Jose State University in California in the United States (US), addressed a group of staff from the UFS Department of Library and Information Services.

Dr Anamika Megwalu, an assessment and engineering librarian at San Jose State University in California in the United States (US), pointed out that building a lasting and sustainable relationship with departments and upholding quality in the library environment is key. 

She addressed a group of colleagues from our Department of Library and Information Services (LIS) on 25 November 2020.

Tight budgets call for proper assessment

Her presentation, titled Library Collection Development, was aimed at sharing her experience of working in the collection development and liaison sections within the LIS ecosystem. 

“This librarian-cum-computer science lecturer has the benefit of both worlds, having worked in private and public academic libraries such as Stafford University and City University of New York respectively,” says Monde Madiba, Deputy Director: Collection Development and Management of LIS at the University of the Free State.

San Jose, the oldest public university in the western US, is located in the heart of Silicon Valley, serving more than 33 000 students enrolled in 10 colleges and 67 departments.

According to Dr Megwalu, the tight budgets that public academic libraries such as San Jose receive, call for proper assessment of library collections in order to deal with the constraints. She emphasised the need to “uphold quality within the constraints”.

Moving from collecting information to creating information

Some of the ideas that Dr Megwalu shared for conducting assessment and collection development, includes the following:
• Change the library’s image from being a collector of information to being the creator of information.
• Consider the size of the different departments: some may need little or no attention due to size, while others may need close attention due to intensive research by lecturers within the department.
• Identify gaps and focus your attention on filling them with the relevant collection.
• Make sure that you are aware of the accreditation period of different programmes, since the role that academic libraries play in collection development is recognised by such agencies.
• Build a lasting and sustainable relationship with departments. This includes knowing the lecturers’ research interests, assisting the newly established departments, attending free webinars, and participating in student activities.
• Ensure equal distribution of the budget and ensure that everyone has equal access to it.
• Create a timetable where everyone knows when to submit requests for prescribed books. Make it clear that it takes approximately three weeks on average for ordered books to be delivered.
• Develop department-specific collection development policies.
• Be ready to move with the times, e.g. replace DVDs in favour of video-streaming services.
• Shift towards a 100% electronic reference collection.
• Consider having an electronic version for popular but currently in-print collections.
• Develop an indigenous collection based on the contributions of communities around the university.
• Create a portal for open educational resources (OERs) from participating institutions across the globe.

“Dr Megwalu’s presentation was not only informative but a testimony that collection development and assessment are dynamic and driven by passion and love,” says Madiba.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
