Use of Lime Piles as an Alternative Method for Stabilisation of Road Embankments

This is a proceeding paper presented at the 9th South African Young Geotechnical Engineers Conference, 13, 14 & 15 September 2017 – Salt Rock Hotel, Dolphin Coast, Durban, KwaZulu-Natal 695 on Use of Lime Piles as an Alternative Method for Stabilisation of Road EmbankmentsThe durability and performance of an embankment depends on its stability. Several options are available for controlling stability and settlement problems associated with embankment slopes. One of them involves using stabilising agents which are suitable for the existing embankment. This research focused on improving the engineering properties of clay soil insitu by using lime pile technique. The clay soil was obtained from a failed embankment along Kamwenge – Fort portal road, chainage 18 + 900. Preliminary tests were carried out to determine if the soil required stabilisation. It had a high liquid limit of 58.6%, plastic limit 26.5% and plasticity index of 32.1. It was classified as CH using the Unified Soil Classification System. Various tests were carried out, for curing days of 14, 21 and 28, to investigate the effect on the engineering properties of the soil. Results showed an increase in Maximum Dry Density, shear strength and a decrease in Optimum Moisture Content and plasticity index hence improved soil properties for embankment slope stability

Affective Governmentality: Governing Through Disgust in Uganda

This article questions the extent to which calculable numbers are indispensable to the government of conduct. By focusing on the role played by disgust in the government of sexual minorities in Uganda, it provides an account of government by emotion, or affective governmentality. This article draws on the literature on disgust, appropriating elements from the various disciplines and perspectives and bringing them under a Foucauldian umbrella. It explores two techniques through which attempts were made to arouse disgust: the sermon and the tabloid exposé. Although such techniques were performed by agents who operated beyond the state, this article contends that the emergence of the Anti-Homosexuality Act 2014 cannot be accounted for without considering the role played by disgust

Reclaiming the educative power of vocational placements: Experiences from agriculture education practice in Uganda

Amidst the global pressure on education systems to harness youth employability and transition to the world of work, there is increased interest in vocational placements. It is evident that Uganda's tertiary education sector, like others in similar context, is struggling to optimise vocational placements for better students’ learning and labour market outcomes. This article explores the “educative” potential of vocational placements offered as a component of study programmes by a public tertiary agricultural training institution in Uganda. It draws on data generated from a qualitative case study that engaged 70 stakeholders namely students, graduates, lecturers, administrators and workplace supervisors. Undertaken between 2016 and 2019, the study reveals the complexities and prospects associated with the design and delivery of vocational placements in stressed education and labour market contexts. From a social constructivist perspective, we make contextual pedagogical propositions for unleashing the educative power of vocational placements in Uganda and similar contexts

New VET theories for new times: the critical capabilities approach to vocational education and training and its potential for theorising a transformed and transformational VET

There is a growing sense that the orthodox set of theories and policies for VET don’t work. This is particularly true in the South where all such Northern theories and policies face the common problem of being constructed for other contexts and then imported. In the light of persistent poverty and inequality; widespread precarious and indecent work; continued concerns about educational access, retention and achievement; and a rising environmental crisis, VET must be transformed to address a new and challenging set of objectives. Here, we offer an exploration of a theoretical approach to VET research that has emerged in the past decade and which offers new insights into how VET can be transformed in order to contribute to the wider transformation agenda around sustainable human development. This is what we term the critical capabilities account of vocational education and training, CCA-VET. We will argue that it is one fertile route towards new thinking about transforming VET in order to support a transformation agenda
