Dr Millard Arnold, UFS Council Member and Senior Consultant at Bowman Gilfillan.

Dr Millard Arnold, Council Member of the University of the Free State (UFS) and Senior Consultant at Bowman Gilfillan, recently contributed to a noteworthy book on leadership and a book on responsive universities. His experience as a journalist and later as a seasoned leader and keynote speaker positioned him well to participate in the book: The Book Every Upcoming, New, and Seasoned Leader Needs to Read – Lessons From Leading Business Minds and Thought Leaders. 

From surviving to thriving

Incorporating collective leadership wisdom for both the leaders of tomorrow and the leaders of today, the book is full of lessons, insights, pep talks, advice, and direction for building your own style and approach to great leadership, and not to shy away from the ecstasy (and sometimes agony) of becoming a significant leader. Packed with the contributions of 48 authors, the book is the antidote to the lack of mentorship in the field. Authors include Brand Pretorius, Edwin Cameron, Marnus Broodryk, Nyimpini Mabunda, and Roze Phillips – to name a few. 

Giving problems to solutions

Dr Arnold’s contribution focuses on fishing out the valuable leadership principles from the sea of leaderships that we are drowning in. “I have found myself in positions of leadership and have had to develop a number of thoughts on leadership which have helped guide me in determining how best to lead,” he writes. This guided him to discover the true essence of leadership, which is problem solving. He asserts that “if there are no difficulties to overcome, no problems to resolve, the leadership is unnecessary”. Leadership has its genesis in problems, he believes. 

Effective leaders make things happen

Among the profound insights that Dr Arnold shares, he highlights the notion that great leaders must understand the problem and have the vision to see the solution. Inevitably, this necessitates the leader to take some risks and to persuade others to get on board. This is only possible if the leader has integrity and ultimately deliver on the promise made. He advises leaders to “ask good questions, listen to the answers, assess the reality, be empathic, and spend a great deal of time on self-reflection”.

Universities must remain relevant 

Dr Arnold also contributed a chapter titled, Poverty, Inequity and Decolonisation: Are Business Schools Responsive to the Challenge? in a book by Chris Brink, The Responsive University and the Crisis in South Africa. The book brings together contributions on the issue of responsiveness from several international university leaders. Dr Arnold’s chapter presents an overview of the impact of colonialism and capitalism on the African mind set and stresses how different South African business schools have responded to the task of being responsive to the challenges confronting the country. It argues that, if carefully managed, business schools can, and should be, vehicles to promote and facilitate positive and constructive change.

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.
