When a catastrophic accident cuts the first manned mission to Jupiter’s moons short in the Astronaut: The Last Push a 2012 American science fiction film – Michael Forrest, the sole remaining astronaut, must endure the three-year return trip to Earth alone. Similarly, how will the next five-year journey of local governance in South Africa manifest itself? Again, I reckon the responses from citizens will vary widely: from widespread cynicism to hope for a better future and from distrust of a dysfunctional system to the belief that service delivery will improve.

In an all-too-familiar scenario, political party campaigns have been littered with promises of how they best represent and advance voters’ interests. In doing so, two helpful facts about these campaigns emerge. The first is that the ANC, DA, EFF, and FF+ have realised that local contexts differ significantly and have framed their messages accordingly. A cursory glance at the broadcastings of these customised campaigns reveals that they aim to provide a safe psychological outlet for community-level concerns. The second is that, in general, the election messaging and adverts of the ANC ranged from apologies to bold statements about who wields power to change the face of local governance. Opposition parties focused on improving the local government system notoriously known for the disregard of citizens’ needs and providing an active voice for the voiceless.

And guess what?

Political parties and candidates may mobilise constituencies as much as they can. However, the next five years of local governance require a significant departure from its status of dysfunctionality to a competent, legitimate political institution that produces satisfactory political outcomes. This legislative and moral mandate depends entirely on local participation in elections.

The three dimensions of increasing voter participation

Better and more meaningful political participation in elections remains a concern in South Africa. In a report for the Ford Foundation, Hahrie Han, a political science professor at the University of California, proposes a framework that details increasing participation and making it more meaningful.

Firstly, people must be able to participate. Declaring election day as a public holiday, President Cyril Ramaphosa removed an important barrier to participation. While some may believe that election day will be just another public holiday, for others – particularly those who are working – there is no need to weigh up whether to take leave for a cause that will not significantly change their lives. Furthermore, the Independent Electoral Commission (IEC) has demonstrated a sense of moral urgency by drawing unprecedented public attention to their voting processes and procedures to protect voters and election officials from spreading the virus at the polling stations.

Secondly, people must want to participate. Here, political parties and election candidates should not take voting as a taken-for-granted part of the repertoire of residents’ political activities. Election campaigns – both online (internet) and offline (door-to-door engagements, posters, and billboards) remain a powerful medium to improve visibility and deliver messages to solicit interest from citizens. But once these campaigns conclude, still, it remains an individual’s choice to want to participate in the elections. While it is difficult to assess the level of voter engagement with the election campaigns under COVID-19 restrictions, the general political climate in South Africa seems to be conducive for free and fair elections. Yet political assassinations continue to cast a dark shadow over the local government elections. This cruel feature of political life in the country serves as an ultimate intimidation tactic. It denies candidates the right to stand for election and citizens to choose their preferred public representatives.

Thirdly, Hahn argues that for people to want to participate in the political process, their participation must matter. Therefore, aside from building a sense of agency and encouraging greater participation in elections, people still need to be convinced that their vote counts and influences decisions at the local level, where voters have the chance to participate directly in the election of local councillors.

Disrupting the balance of power in local councils 

Regardless of the challenges it faces, the ANC remains in pole position to retain most of the local councils it leads. I believe there is much to be discontented about, but opposition parties – including civic forums – have yet to build the power to break the stranglehold the ANC has on elections – and that is no small task.

Interestingly, in contrast to the DA, the ANC has paradoxically avoided announcing their mayoral candidates in direct response to prevent the electoral backlash it received in the metros during the 2016 local government elections. Yet, except for a few local councils in several provinces, the metros are precisely where the most significant disruption to the balance of power will occur. 

Whether political parties will deal with the standoffs of coalition politics in hung councils, while broaching complex issues, remains a concern for South Africans. But elections remain an excellent opportunity for citizens to participate and influence local political decision-making.

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass
segmentation identification

Breast cancer is the leading cause of female mortality in developing countries. According to the World Health Organization (WHO), the low survival rates in developing countries are mainly due to the lack of early detection and adequate diagnosis programs.

Seeing the picture more clearly

Susan Acho from the University of the Free State’s Department of Medical Physics, breast cancer research focuses on using mathematical methods to delineate and classify breast masses. Advancements in medical research have led to remarkable progress in breast cancer detection, however, according to Acho, the methods of diagnosis currently available commercially, lack a detailed finesse in accurately identifying the boundaries of breast mass lesions.

Inspiration drawn from pioneer

Drawing inspiration from the Mammography Computer Aided Diagnosis Development and Implementation (CAADI) project, which was the brainchild Prof William Rae, Head of the department of Medical Physics, Acho’s MMedSc thesis titled ‘Segmentation and Quantitative Characterisation of Breast Masses Imaged using Digital Mammography’ investigates classical segmentation algorithms, texture features and classification of breast masses in mammography. It is a rare research topic in South Africa.

 Characterisation of breast masses, involves delineating and analysing the breast mass region on a mammogram in order to determine its shape, margin and texture composition. Computer-aided diagnosis (CAD) program detects the outline of the mass lesion, and uses this information together with its texture features to determine the clinical traits of the mass. CAD programs mark suspicious areas for second look or areas on a mammogram that the radiologist might have overlooked. It can act as an independent double reader of a mammogram in institutions where there is a shortage of trained mammogram readers. 

Light at the end of the tunnel

Breast cancer is one of the most common malignancies among females in South Africa. “The challenge is being able to apply these mathematical methods in the medical field to help find solutions to specific medical problems, and that’s what I hope my research will do,” she says.

By using mathematics, physics and digital imaging to understand breast masses on mammograms, her research bridges the gap between these fields to provide algorithms which are applicable in medical image interpretation.
