The year 2021 marks the 58th anniversary of the establishment of the Organisation of African Union (OAU) on 25 May 1963. The month of May is therefore celebrated annually as Africa Month. This piece, in essence, is a craving to respond to an often-articulated question: is Africa Month a moment of celebration or introspection? The former would have been preferred had the various freedoms offered by the organisation been more realistic and dealt with the concrete challenges bedevilling the continent’s population. 

At the onset, it ought to be acknowledged that the organisation was not forged with the intent of improving the living conditions of its population but to safeguard the recently won independence and sovereignty of its member states. Against this backdrop, the notion of non-interference in the domestic affairs (Uti Possidetis Juris) of states became its guiding principle, thereby fostering a culture of silence on abuses perpetuate by African rulers against their citizens.  Having said that there were notable illustrations of leaders such as Julius Nyerere, Kenneth Kaunda, and Samora Machel, who individually and collectively ‘invoked the notion of humanitarian intervention’ and waged crusades to relieve Ugandans from the jaws of Idi Amin. 

Indeed, one of the significant achievements of the OAU during this era was the adoption of the African Charter on Human and Peoples’ Rights (Charter) in 1981. The instrument may be seen as a trumpeting of freedom, as it considers the rights and wellbeing of Africans sacrosanct and uncompromising. It is important and perhaps enthralling that all African states are parties to the Charter. While the large-scale ratification could enhance its moral force, it could also be used as a red herring to cover up various atrocities in hostile countries.

Where are we?

In 2002, African rulers meeting in Durban, South Africa, adopted the Constitutive Act, transforming the OAU into the African Union (AU). The new Act perhaps seems to be breathing fresh air into Africa’s rights struggle. In stark contrast to its forerunner, the Constitutive Act authorises the AU to intervene in a situation where citizens are threatened by grave danger perpetrated by their governments or external forces. Remarkably, article 3(k) calls for raising the ‘living standards of African people’. Going by these aspirations, one might speculate that Africans are in for a cheery and jolly ride.

Remarkably, while the Act addresses several aspects of the continent’s socioeconomic issues its operationalisation remains the captive of competing for national interests of AU states. Four key setbacks merit consideration here.

Instability: The landscape of Africa is punctuated by rulers’ embezzlement of public funds, ethnic privilege, and siphoning resources to one’s home village to the detriment of others. This bias tends to incite discontent and hostilities, even as one of the popular rhetoric of the infamous Boko Haram is to addressing Nigeria’s North-South resource disparity. By the same reckoning, hundreds of women and children have been displaced or killed from avoidable hostilities in geographical enclaves such as Cameroon, DR Congo, Mozambique, and Sudan.

Injustice: State security agencies and specifically the police force have evolved to be intimidators rather than the protective machinery they ought to be. More disturbingly, access to justice seems to be a pipe dream, as legal fees and prolonged trials make it burdensome for victims to seek remedies. As a common practice, many judicial systems across Anglophone, Francophone, and Lusophone countries are still modelled on ancient colonial systems, with lawyers and judges using convoluted legal jargon which frustrates rather than assists victims of abuse. 

Poverty: 40% of the continent’s population lives in extreme poverty or on <$1 (approx. R14) per day. Indeed, this figure is sobering. A reader might agree that the New Partnership for Africa’s Development (Nepad) may be seen as the primary document for reversing this trend. The document has, however, been criticised as given superficial treatment to the basic entitlement of vulnerable groups, and without feasible strategies on issues of underdevelopment.  It speaks to enhancing greater access to services, but segregates this aspiration from how the impoverished could access these essentials. Without a commitment to enforceable socioeconomic goods, such as health care, education, food, social security, the document may be seen as placing a stamp on the skewed access to resources already pervasive in local communities.

Covid-19: The onset of the pandemic calls for total marshalling of the continent’s fiscal and human resources. Sadly, the virus has claimed the lives of eminent cadres, teachers, and trade unionists who could have played a key role in this regard. South Africa alone has recorded more than 54,620 deaths, leaving behind hundreds of orphans.   Still, the ramifications are likely to be more significant, altering the structures of society and putting a strain on the financial resources of weak states. 

What ought to be done?

One golden thread running through these challenges is the weakness of the AU to forge effective institutions to restrain the excesses of states, monitor the government’s compliance with human rights obligations, and accountability. If the organisation seeks to improve human rights in Africa, it ought to revive debates towards Pan-Africanism and regional integration. At present, artificial borders erected by colonisers have created states which are simply not viable economic and political units. To this end, continental integration is the effective means of accelerating economic growth, uplifting the least developed countries, and domestically-based transformative development.

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.
