Interactive tools supporting agriculture in the wine industry

Claassen, Hester January 2012 (has links)
Thesis (MTech(Design))--Cape Peninsula University of Technology, 2012 / To design from a human perspective rather than from existing technological opportunities, and involving multiple stakeholders with their different perspectives, is an important aspect of participatory design and user-centered design. This thesis project was an explorative study done on a wine estate, in the Western Cape, South Africa, to find novel ICT solutions, for supporting co-operation and planning between multiple and individual work tasks in the work practice. This research explored potentials to manage multiple stakeholders and use their different perspectives to inform design research. The thesis project shows the ethnographic research gathered through video shadowing, workshop results involving the users to contribute to the development of the design by acting with a projection, leading up to a design opening and further focused on the concept development with the stakeholders.The thesis proposes a simulated concept namely the Visual Calculator (VC). This system is designed to involve several participators within a work practice. It supports calculation activities for spraying and buying chemicals. It saves the user time by incorporating standard calculations to output needed information faster. It supports planning, management and record keeping aspects of the farm manager’s work practice in the vineyard spraying process. Although the concept was more fully developed for the farm manager, the VC involves two other work roles including the owner and foreman. The concept focuses on a human centered perspective, instead of making the system fully automated, giving users control and not controlling the users. For this to be successful work should be divided and have equal responsibilities, each stakeholder can contribute and value their part of the work, knowing where it fits in, why it is important and how it influences other aspects of the work practice. The research outcome involves, envisioning the future potentials of the design (VC), design for participation, a way to identify design openings, problem solving and conceptualizing by utilizing user’s strengths.

Principals' influences on teacher professional development for the integration of information and communication technologies in schools

Van Niekerk, Molly Patricia 02 May 2009 (has links)
The effective and sustainable use of ICTs (Information and Communication Technologies) in education has become commonplace as it is necessary to keep up with demands of the 21st century. ICT in education has become a tool for the empowerment of both teachers and learners for better teaching and learning. Although various ICT strategies and initiatives are implemented across South Africa, no system-wide effective and sustainable ICT integration in schools has yet come about. The pace of integration is slow and teachers avoid using ICT in their teaching and learning practices due to insufficient training. The aim of teacher professional development (TPD) is to improve teachers’ ICT application skills and knowledge, as well as to enable teachers to integrate ICT effectively in their classroom practices. Principals play a vital role in leading school reform, implementing innovations and bringing about change. The widespread assumption that high-quality leadership is an essential dimension of successful school management, leads to the question of how principals can influence teachers’ effective and sustainable integration of ICT into classrooms through TPD activities. Therefore, the purpose of this research was to determine the influence that principals have on teachers’ ICT integration through TPD. As school leadership is frequently cited as an essential for the successful integration of ICT into education, the very position of the principal is associated with authority, accountability and power. My initial research is based on Stoner’s (1999) Adapted Life Cycle Model of Learning Technology Integration. I used this model to illustrate the principals’ influence on teachers’ integration of ICT into education. From this review subsidiary questions emerged. Qualitative research through in-depth interviews formed the basis of an interpretative perspective, allowing principals to reflect on ICT integration, as well as their influence on teachers’ use of ICT. This study followed a basic grounded theory approach where I assumed an inductive stance and strived to derive meaning from the data in order to develop new theory. Pre-defined theoretical criteria determined the selection of the respondents to ensure validity of the data. The seven principals represented secondary schools across cultural and socio-economic levels. The perceptions and experiences of the principals were analysed, compared, and patterns of influence were identified. This study indicated that principals do not only influence the integration of ICT in classrooms through their leadership and management styles, but also through their attitude toward ICT integration, knowledge on related ICT and TPD issues, as well as their strategic thinking on ICT integration. Emerging findings on the role of the principal lead to new insights on the empowerment of teachers. The study resulted in a proposed theoretical framework that indicates the interrelatedness of the emerging patterns that influence the principals’ role through TPD. / Thesis (PhD)--University of Pretoria, 2009. / Curriculum Studies / unrestricted

An investigation of information security policies and practices in Mauritius

Sookdawoor, Oumeshsingh 30 November 2005 (has links)
With the advent of globalisation and ever changing technologies, the need for increased attention to information security is becoming more and more vital. Organisations are facing all sorts of risks and threats these days. It therefore becomes important for all business stakeholders to take the appropriate proactive measures in securing their assets for business survival and growth. Information is today regarded as one of the most valuable assets of an organisation. Without a proper information security framework, policies, procedures and practices, the existence of an organisation is threatened in this world of fierce competition. Information security policies stand as one of the key enablers to safeguarding an organisation from risks and threats. However, writing a set of information security policies and procedures is not enough. If one really aims to have an effective security framework in place, there is a need to develop and implement information security policies that adhere to established standards such as BS 7799 and the like. Furthermore, one should ensure that all stakeholders comply with established standards, policies and best practices systematically to reap full benefits of security measures. These challenges are not only being faced in the international arena but also in countries like Mauritius. International researches have shown that information security policy is still a problematic area when it comes to its implementation and compliance. Findings have shown that several major developed countries are still facing difficulties in this area. There was a general perception that conditions in Mauritius were similar. With the local government's objective to turn Mauritius into a "cyber-island" that could act as an Information Communication & Technology (ICT) hub for the region, there was a need to ensure the adoption and application of best practices specially in areas of information security. This dissertation therefore aims at conducting a research project in Mauritius and assessing whether large Mauritian private companies, that are heavily dependent on IT, have proper and reliable security policies in place which comply with international norms and standards such as British Standard Organisation (BSO) 7799/ ISO 17799/ ISO 27001. The study will help assess the state of, and risks associated with, present implementation of information security policies and practices in the local context. Similarities and differences between the local security practices and international ones have also been measured and compared to identify any specific characteristics in local information security practices. The findings of the study will help to enlighten the security community, local management and stakeholders, on the realities facing corporations in the area of information security policies and practices in Mauritius. Appropriate recommendations have been formulated in light of the findings to improve the present state of information security issues while contributing to the development of the security community / Computing / M.Sc.
