24 February 2021 | Story Compiled by the Teaching and Learning Division of the UFS Library and Information Services


Writing a good research report does not come naturally to most of us, and it can often be a daunting task if you have never done it before – which is often the reality that most students find themselves faced with only later on in their academic journey. Realising this gap, the UFS Library and Information Services (UFS LIS) adopted the Best Assignment project as one of its flagship projects in collaboration with faculties from all three campuses. The project is meant to inspire and motivate students to make an extra effort in producing high-quality assignments and harness their research skills at undergraduate level. This is also in line with the university’s research-focus strategy. 

Students prepare, write, and present their assignments.  When the project was first launched, only two assignments were received. In 2020, this number tripled when a total of 13 assignments were received. Among the 13 assignments, 12 were individual assignments and one was a group assignment. Two faculties participated in the project, namely the Humanities and Natural and Agricultural Sciences. Below is a summary and extracts from the students’ work.

Seeqela Ntsibiseng: Temperature and light effect on moth activity/numbers

In this article, students investigated the effect of temperature and light on moth activity or numbers. There is scientific proof that moths are mostly active in warmer temperatures and in medium light pollution. The study was conducted at sites in the Free State, Gauteng, and KwaZulu-Natal. 

 
Mollo Retshedisitswe: The effects of ambient light and temperature on moth behaviour in different South African locations

Insects, the smallest, most diverse animals in the world, can be great biological indicators. Moths are one of the few insects that need to be conserved in order to inform us about the environment. This study investigates how moths are affected by ambient light and temperature in three locations in South Africa. The data was collected by observing the number of moths present at a light source – in this case a streetlight – at three hourly intervals for several days in April and May. 

 
Faculty of the Humanities
Lecturer: Prof Nyasha Mboti
Department: Health and Development Communication 
Modiehi Koti: Alcoholism/Alcohol Abuse: Sejake Square in Bloemfontein
“I chose to focus on this selected health issue because it is a big and serious issue in my community. Too many people have given up their lives. They live for alcohol, they drink every day, and neglect their families. My father was an alcoholic – growing up in a household where there is an alcoholic is not nice. He passed away of a liver problem because of alcohol. I do not want other families to go through what I went through, seeing a loved one destroy their lives because of drinking alcohol every single day. I do not want to see households break because of alcohol abuse.”

Mpusheng Isaac Manasoe: Femicide in South Africa: South African Communities
“Nothing much is being done to address issues of gender-based violence or femicide. Women have marched and protested as if this is a problem they need to fix, although they are the victims and men being the perpetrators here. This isn’t an issue that women can or must fix. Men are the problem here, not the other way around. We live in a society ruled and governed by laws and systems that embed beliefs such as men are ‘superior’ to women. Men need to start realising that their toxic behaviours aren’t normal just because their beliefs are enabled by laws and systems, as well as unstable psychological issues.”
 

Dimakatso Macu: Drug addiction, specifically nyaope, among lower income groups in the township surroundings – Tembisa

“I have chosen to focus on this selected health issue because it is one of the biggest problems in our country, South Africa. It affects so many young people and families who never actually know how to deal with that situation. Nyaope kills in so many ways – it does not only affect the person using it, but even the community at large. Criminal activities such as housebreaking, robbery, and rape are on the increase. The younger generation in the community may even be influenced to consume the drug. So, choosing this health issue meant more awareness on nyaope, which means that communities will know how to deal with this problem.”


Lilita Majokweni: Drug and Alcohol Abuse: Soweto, Gauteng
“I have chosen to focus on this selected health issue because of the effects it has on a person physically, mentally, and emotionally and how it affects the families of such people. Alcohol and drug abuse are a serious problem in South Africa, especially in Soweto, as Soweto has one of the highest violence and crime rates in South Africa related to alcohol and drug abuse. It is also affecting the youth, as they turn to drinking and drugs at an early age due to social peer pressure or due to family problems.”  

Mathapelo Api: Violent crime: Johannesburg, Alexandra
“I have chosen to focus on this selected health issue because violent crime in South Africa keeps increasing. Each day there is a new report on peoples’ deaths due to violent crime. Women and children are becoming the greatest victims. Also, the scarcity of jobs in South Africa is the reason I chose this issue, because an idle mind is the devil’s workshop. If people from Alexandra had jobs, they could afford to move out of their slums to find places with proper sanitation for them and their children. Poverty and economic stress are the most common daily problems that people of Alexandra have to deal with, which are the key reasons for crime.”

Nkosingiphile Mkhwanazi: Substance abuse: Western Cape, Cape Town
“I have chosen to focus on substance abuse as a health issue because the consumption of alcohol and medications has numerous adverse health effects. Firstly, the behavioural issues whereby people suffer from social problems, depression, suicidal thoughts, which sometimes leads to violence. Secondly, because it has killed many dreams for South African youths who abuse drugs. Thirdly, because I want this issue to be addressed in any possible way to avoid teenagers from dropping out of school. The last reason why I have chosen this is because I have been a victim of substance abuse at an early age; fortunately, I found help and I was able to proceed with my dreams.”

Jana de Kluiver: The Political Economy of Nigeria as an Emerging Power

This essay attempted to establish whether Nigeria’s political economy is of such a nature that the country can be considered an emerging power in the global community. The research methodology used in this essay consists of a literature review that includes the use of internet articles, books, reports, and academic articles. Firstly, a conceptual clarification with relation to political economy was provided. Afterwards, Nigeria’s political economic history was discussed in an attempt to provide the analysis with context. Thirdly, a study was done on the strengths and weaknesses in Nigeria’s political economy, followed by a critical analysis of Nigeria’s current political economic prospects, taking into account the effects of COVID-19 and how it has influenced Nigeria’s standing in the international political economy.'

Lumanyano Ngcayisa: A critical discussion of the phenomena of rentier states: The case of Qatar
The topic, ‘A critical discussion of the phenomena of rentier states: The case of Qatar,’ provides a guide to the study of rentierism as a theoretical concept while focusing on one case in the Middle East. In an ever-changing global economy, rentier states are challenged with diversification (adapt or die), which raises the question of their sustainability. The article investigated the economic implications of the rentier states after noting both contributions and limitations of rentierism. The article provided insight into the phenomenon of rentier states while providing a critical discussion of the functionality, highlighting economic implications on these economies and their citizenry, particularly Qatar's case.


Department: Language Practice
Lecturer: Dr Marlie van Rooyen
Calista Lambrechts: Discuss the contributions of scholars that have included non-western practices in the theoretical realm of translation and interpreting studies. 

“Translation and interpreting have been around since the beginning of human history, but Western theories and Eurocentric stereotyping seemed to have become the dominant view in this practice. This Western perspective has spread, “permeat[ing] the world” and seeping into countless cultures (Tymoczko, 2006: 13). By following these Western theories and examples of translation and interpreting that have been dominating the ideas, concepts and perceptions related to Translation1 for so long, our view is limited, and the study of translation theory is greatly restricted, keeping us from exploring and looking at all the other nooks and crannies of the world. We have been so used to this Western way of things, that many of our own studies and examples shows us just how powerful a hold these theories of the West have had.”

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
