KovsiesCare - Clean Up Read More
Tsietsi Ngobese, through the Wesolve4x Cleaning My Planet Campaign, motivated citizens to collectively fill over 23 000 refuse bags to date.

The mission: To collectively fill 20 million refuse bags every Saturday with the help of 20 million people who are cleaning their own communities and our planet for an hour. The message: My planet, my responsibility.

The mission and message that the Wesolve4x Cleaning My Planet Campaign wants to convey, is based on a simple premise: Get community members to donate one hour of their time to cleaning duties every Saturday for the next 20 years until 2039. At the same time provide a continuous educational programme about waste management to the general public and to schools in order to empower them to take responsibility.

Address trash blindness


Tsietsi Ngobese, Chief Executive Officer of this initiative and BSc Actuarial Science graduate, says he understands the transformative power of education and the role it plays in transforming diverse communities. Through outreach programmes in our community and schools, we are slowly eliminating generational trash blindness. We also tackle some of the social determinants of health by encouraging healthy living conditions within our communities through good waste management and recycling. 

It is important for Tsietsi to add value to society. He believes that the Wesolve4x Generation will transform the world for the better through education and empowering all citizens.

The campaign – officially endorsed by Miss Earth South Africa, Catherine Constantinides – was launched on the UFS Bloemfontein Campus as well as the Abram Hlope Primary School in Katlehong on 4 May 2019.

“We want to promote the benefits of a clean and healthy environment for future generations,” said Tsietsi. 

Since their inception, the group has collectively filled over 23 000 refuse bags with the help of active citizens. 

Challenge accepted

When former lecturer, Jan Blomerus, once challenged his Actuarial students to protect the environment in order to decrease the mortality rate (from natural disasters because of the effect of climate change), Tsietsi accepted the challenge. “By inspiring excellence and transforming lives, the UFS plays an important role; I started to believe that I can address societal challenges in the communities I am an integral part of,” he said.

When Tsietsi saw trash piling up everywhere and children playing at illegal dumping sites, he became concerned about the health risk to society. He believes the dumping area is contaminating the air and water around the dumping site. 

“I had to be part of the solution to start cleaning up, and most importantly, educating myself and others to continuously take responsibility for our own waste and change our thinking about littering. This is a generational issue and needs a generational approach to unlearn all habits of littering,” Tsietsi pointed out. 

As part of his vision, Tsietsi plans to reduce the waste taken to landfill sites and to increase that which is taken directly from households to recycling plants. He also wants to encourage people to find creative ways of converting what has previously been wasted into something useful. “This action can encourage individuals to generate an income from waste,” he said.

Take action

Tsietsi invites all members of the Mangaung community to get involved in the project. This is your opportunity to make a difference on Mandela Day. You can;
provide sponsorship for educational content on effective waste management, economic opportunities, and health issues to the general public and to schools;
provide refuse bags, plastic gloves or hand-washing soap (used by community members in every clean-up session);
join in a collective effort to clean your community by meeting at designated schools or any designated community assembly point on a Saturday (contact 011 307 2005 or info@wesolve4x.com for more information).

Harvard couple to present lectures on Biostatistics and Mathematics at the UFS
2015-12-07


Professor Donald Rubin

Prof Donald Rubin (John L. Loeb Professor of Statistics at Harvard University) and Elizabeth Zell (MStat - mathematical statistician in the Division of Bacterial Diseases) will visit the University of the Free State (UFS) where they will present lectures on their respective work.

Over his prestigious academic career, Prof Don Rubin’s 400 publications and 13 books have earned him around 180 000 citations at an h-index of 113. He is one of the most cited statisticians/mathematicians/economists/psychologists in the world over the last 10 -15 years. He has supervised 35 PhD candidates as sole-supervisor, 17 more as co-supervisor, with a further eight in the pipeline.

Prof Rubin who will meet with UFS academics in the Department of Mathematics and Actuarial Sciences will also deliver a lecture: Rerandomisation to improve covariate balance in experiments.

Randomised experiments are the “gold standard” for estimating causal effects, yet in practice, chance imbalances often exist in covariate distributions between treatment groups. If covariate data are available before units are exposed to treatments, these chance imbalances can be mitigated by first checking covariate balance before the physical experiment takes place. Provided a precise definition of imbalance has been specified in advance, unbalanced randomisations can be discarded, followed by a rerandomisation. This process can continue until a randomisation yielding balance according to the definition is achieved. By improving covariate balance, rerandomisation provides more precise and trustworthy estimates of treatment effects.

Prof Rubin received an honorary professorship from the Faculty of Natural and Agricultural Sciences at the UFS.


Elizabeth Zell

The lecture will take place on:
Date: Tuesday 8 December 2015
Time: 16:00
Venue: Albert Wessels Auditorium, Bloemfontein Campus

Zell earned her Master’s degree in Statistics at North Carolina State University, and for more than two decades, was an active bio-statistical researcher in various offices of the Centers for Disease Control (CDC). Since 2013, she has been the Principal Statistician and President of Stat-Epi Associates, Inc. Her 150+ publications have earned her 14 500 citations at an h-index of over 50. She is a Fellow of the American Statistical Association, and, in 2010, she received the Statistics Section Government Award for outstanding contributions to statistics and public health by the American Public Health Association. During her career at the CDC, she earned more than 20 CDC research awards and honours.

She will deliver two lectures at the UFS. The first is entitled A Potential Outcomes Approach to Documenting the Public Health Impact of the Introduction of PCV13 for the Prevention of Invasive Pneumococcal Disease. The topic of her second lecture is: Assessing the Effectiveness of Intrapartum Antibiotic Prophylaxis for Prevention of Early-Onset Group B Streptococcus Disease through Propensity Score Design

Elizabeth’s lectures will take place on:
Date: Wednesday 9 December 2015
Time: 10:45 and 13:00
Venue: West Block 111, Bloemfontein Campus
