Burnout affects productivity in higher education
Elizabeth Nchapi’s study says burnout has adverse results for both employer and employee.

Staff members who are chronically exhausted may develop a cynical attitude towards their work and are likely to underperform, therefore feeling incompetent or experiencing a sense of reduced accomplishment. This is according to a research study by Elizabeth Nchapi, Head: Finances, on the University of the Free State’s Qwaqwa Campus. The study, which formed part of her Master of Arts (Higher Education Studies), also gives a comprehensive view on potential consequences for individuals and the organisation itself.

“The study was informed by my experience as a finance professional working at a higher-education institution where most of the research on burnout has mainly been around academic staff, hence this study focused on administrative staff,” she said.

Work environment stressors for administration staff

“Administrative staff in this sector have a responsibility to provide quality service not only to the academic core business of the institution, but also to the external stakeholders. Their working conditions require extensive multitasking, as they may often be expected to perform external roles or in fields other than their regular functions. Given that they continuously work under these circumstances, members may increasingly suffer from pressure leading to stress and burnout, which is a state of mental and physical exhaustion caused by one’s work environment.”

Work-environment stressors that lead to burnout, according to the study, include work overload, student interaction, team conflict, role ambiguity, job insecurity, lack of organisational support, lack of motivation, and workplace bullying.

Results of burnout

“Some of the potential consequences of burnout that have been identified as serious health problems may include, among others, sleep disturbances, anxiety, depression, and respiratory infections,” said Nchapi.

“Previous studies have shown that burnout does not only impact employees’ physical and psychological well-being. It also has significant consequences for the organisations and the employers. These include absenteeism, alcohol abuse, and poor organisational commitment, which ultimately result in poor performance,” she added.

The study further emphasises that personal and organisational consequences cut across the lines of gender, age, race, and employment levels.

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.
