The knowledge continuum as an enabler for growth and sustainability in the South African basic education system / Mariè Steenhuisen.

Steenhuisen, Maria Jacoba January 2012 (has links)
The poor state and failure of the basic education system in South Africa gave rise to this research. The wave of knowledge loss experienced in the last two decades is expected to carry on and will continue to deplete the basic education system’s knowledge base, severely affecting the already poor quality of education as well as the future economic growth and sustainability in South Africa. The main research objective was to establish whether future growth and sustainability in the basic education system in South Africa is achievable; which factors it is influenced by; and how knowledge continuity could impact on future growth and sustainability. A multidisciplinary approach focusing on organisational performance, knowledge management, individual and organisational behaviour and organisational development was followed. The nature of growth and sustainability and knowledge continuity in organisations was explored by following a contextualisation theory-building process. The main objective of the empirical research study was to determine by means of quantitative research the degree to which the influencing factors would enhance or impede growth and sustainability in an organisation. A quantitative survey method was followed. A questionnaire was developed and the survey was performed in 6 primary and secondary schools of the basic education system in South Africa. The questionnaire was found to be reliable with a Cronbach’s alpha of .8060. In the descriptive factor analysis process, principal component factor analysis was conducted, which described the five constructs that would influence growth and sustainability. These constructs’ dimensions produced significant intercorrelations which indicate that the dimensions are for the most part intercorrelated with each other in contributing to growth and sustainability. The multiple regression analysis indicated that knowledge loss would have an exceptionally strong impact on knowledge; and that knowledge, information and performance would significantly predict growth and sustainability. Organisations should change the focus for growth from physical assets to the development of intellectual capital, and knowledge continuity should form part of an organisations’ business strategy and mission. Knowledge continuity will only be successful if a culture conducive of trust and knowledge sharing and transfer exist, and are supported by effective and appropriate human resource practices and incentives. A structural equation model development strategy produced a knowledge continuity model aimed at enabling future growth and sustainability, based on the constructs confirmed in the factor analysis. The model indicated that there is a direct causal relationship between knowledge, information and performance with growth and sustainability. The regression analysis showed that most of the intercorrelations are significant, thus confirming the theory. The newly developed questionnaire and structural equation model should enable organisations to measure the degree to which the enhancing individual and organisational behavioural factors of growth and sustainability are in place and provide the measurement outcomes that would identify the factors that need to be focused on to improve and enable future growth and sustainability in an organisation. / Thesis (MBA)--North-West University, Potchefstroom Campus, 2013.

The analysis of a cell phone record as a source of intelligence in the investigation of copper cable theft

Van Niekerk, Anna-Marie 02 1900 (has links)
Copper cable theft (CCT) has a devastating effect on the South African economy, and essential services such as TELKOM, ESKOM AND TRANSNET have been seriously disrupted, due to CCT. This dissertation focuses on the value of the cell phone record as a source of intelligence during (CCT) investigations. The cell phone industry is growing each year, and millions of people worldwide possess a cell phone. Some of these people are involved in criminal activities – which mean that cell phones, with their advanced capabilities, hold evidence which relates to crime. The activation of cell phone activity is contained on a cell phone record, and, when analysed, such information becomes intelligence which has a positive impact on CCT investigations. The purpose of this study is to assist and give guidance to investigators, in order to analyse the cell phone record(s) of CCT thieves. / Criminology and Security Science / M. Tech.

Correlación entre conocimientos sobre consecuencias de la obesidad y grado de actividad física en universitarios

Ocampo Mascaró, Javier, Silva Salazar, Vera Jimena, da Costa Bullón, Abilio 03 February 2015 (has links)
Introducción. El objetivo del presente estudio es determinar si existe correlación entre los conocimientos sobre las consecuencias de la obesidad y el grado de actividad física de las personas. Métodos. Se realizó un estudio transversal analítico durante los años 2013 y 2014. Participaron 215 alumnos de pregrado seleccionados por conveniencia no relacionados a carreras del campo de la salud en una universidad de Lima, Perú. Se evaluó el grado de actividad física utilizando el International Physical Activity Questionnaire (IPAQ) y el nivel de conocimientos sobre consecuencias de la obesidad utilizando la escala Obesity Risk Knowledge-10 (ORK-10). También, se consignó las fuentes de información de donde obtuvieron el conocimiento para responder dicho cuestionario. Resultados. La mediana de edad fue 20 (rango intercuartílico=4) y 63% eran mujeres. De acuerdo al IPAQ, 53,9% realizaban actividad física alta, 35,4%, moderada y 10,7%, leve. Se encontró una correlación muy baja (rs=0,06) entre el puntaje del ORK-10 y la cantidad de equivalentes metabólicos/minuto consumidos por semana, pero no era significativa (p=0,38). Las personas informadas por medios de comunicación y por personal de salud obtuvieron mayores puntajes en el ORK- 10 que quienes se informaron por otras vías (p<0,05). Conclusiones. La correlación entre los conocimientos sobre consecuencias de la obesidad y el grado de actividad física es muy baja. Es necesario utilizar enfoques multidisciplinarios que incluyan todos los determinantes de la realización de actividad física para poder lograr cambios en la conducta de la población.
