Description: There is a rising trend in the use of Information Communication Technology (ICT) by academics to work after regular working hours. The dual nature of ICTs enhances work flexibility and also encourages academics to use ICTs to engage in supplemental work practices. The objective of this study was to investigate the effect of family relationships on technology assisted supplemental work and Work-Life Conflict (WLC) experienced by academics in a higher education institution in South Africa. Specifically, the moderating roles of marital status and children were taken into consideration in investigating the relationship between TASW and WLC. A quantitative research approach was adopted and an online survey was used collect data. The WLC scale and the TASW scale were as well used. The sample consisted of academics from a higher education in South Africa (n = 216). The results of the research revealed a significant relationship between TASW and WLC. TASW is a significant predictor of WLC. Furthermore, the results revealed that marital status and children significantly moderated the relationship between TASW and WLC. This study contributes further knowledge to the emerging field of research relating to TASW in a South African context. This study also emphasises the implications of using ICTs and their potential to encourage academics to extend their working hours. In particular, this study outlines the important role of marital status and children in influencing the relationship between TASW and WLC.

Description: Experiments are performed to investigate the single-phase flow and flow-boiling heat transfer augmentation in 3D internally finned and micro-finned helical tubes. The tests for single-phase flow heat transfer augmentation are carried out in helical tubes with a curvature of 0.0663 and a length of 1.15 m, and the examined range of the Reynolds number varies from 1000 to 8500. Within the applied range of Reynolds number, compared with the smooth helical tube, the average heat transfer augmentation ratio for the two finned tubes is 71% and 103%, but associated with a flow resistance increase of 90% and 140%, respectively. A higher fin height gives a higher heat transfer rate and a larger friction flow resistance. The tests for flow-boiling heat transfer are carried out in 3D internally micro-finned helical tube with a curvature of 0.0605 and a length of 0.668 m. Compared with that in the smooth helical tube, the boiling heat transfer coefficient in the 3D internally micro-finned helical tube is increased by 40–120% under varied mass flow rate and wall heat flux conditions, meanwhile, the flow resistance is increased by 18–119%, respectively.

Description: There is growing recognition globally that the current organisational change management methodologies and practices are ineffective. This admission is based on the fact that change efforts implemented in organisations do not produce the desired results in terms of set change objectives. This assertion is evidenced by the dismal success rate in the implementation of organisational change initiatives. Empirical studies conducted previously by authors such as Hattingh (2004), Balogun and Hope Hailey (2004), Bregman (2009), Lotich (2011), and Choi and Ruona (2011) have confirmed that there is indeed a high failure rate in the implementation of organisational change efforts. The high failure rate that organisations record is attributed to managers’ neglect of the elements and dynamics of change, which constitute the human dimension of change. People’s perceptions of change form part of the dynamics of change which need to be seriously addressed if success in the implementation of organisational change efforts is to be attained. Empirical studies that seek to validate the claim that perceptions play a critical role in shaping people’s attitudes towards change and consequently their responses to change in terms of their reactions and resistance to change, have somehow been very limited. This is what this study sought to do – to investigate, establish, explore and understand the role that perceptions play in influencing people’s attitudes towards change, thereby influencing the status of change in terms of success or failure. The undertaking of the study on perceptions was to ensure that managers understand the influence that perceptions have on people’s attitudes towards change. The researcher conducted a literature study in order to contextualise the role of perceptions in influencing people’s attitudes within the offender correctional environment in the Department of Correctional Services of South Africa. Two survey questionnaires, one for correctional officials and the other for offenders, were utilised for purposes of collecting data. The results of the study revealed that perceptions play a significant role in shaping people’s attitudes towards change and consequently their reactions to and experiences of change.

Reflexive grappling with theory and methods of text analysis : race and racism represented in history textbooks

Description: Theoretical and methodological matters pertaining to school textbook analysis are an under-researched and under-documented area of specialisation. In this article I attempt to contribute to this field by reflecting on my own experience of grappling with these issues as relevant to the study of a number of South African school history textbooks. The topic of investigation is that of race and racism. I use this as a vehicle for operationalising the theoretical and methodological issues at hand. A key issue is whether historians and other ‘scientists’ make the methods of their disciplinary discoveries explicit or not, and the implications this could have for developing historical understanding. In the second part of the article I explain the theoretical position I assume towards the object of my study. It is a hermeneutic realist stance; a stance that attempts to use the researcher’s (own) particular historically and culturally conditioned mindset in the interpretive process. In some cases this led to an interpretation of the messages communicated in the textbook as flat and sterile, reinforcing stereotypes, while in others the reader is drawn into a discourse that tends to appeal to his or her humanity rather than judgement.

The raising of the flag in ‘Volkstaat’ Orania : perspectives on a school ceremony

Description: In this paper we present an analysis of a social practice that was observed during a two month ethnographic field study in a school in the Afrikaans community of Orania. It is a flag ceremony that is carried out at the end of each week. We use two different framework positions from which to discuss the ceremony - Turner’s (2009) interpretive framework with which to analyse social action as ritual and Reckwitz’s (2003) “theories of practice” approach to see how it could be understood as forming part of everyday life. From the view of the former, rituals are mostly associated with power relations and initiation, and have rigid time and content structures. From the view of the latter, a type of “praxeological” approach, the observed ceremony could be interpreted as an integral part of everyday school life that is embedded and is an embodied routine, without rational, reflective practice. The aim of this article is to juxtapose and discuss these two alternative approaches as they apply to the observed ceremony. For this we turn to the work of Erving Goffman, who combines ritual theory with an everyday routine focus. The conclusions point to the need to examine the underlying logic of practices instead of only describing their evolving dynamics.
