This research seeks to determine the impact of the use of e-mail between lecturers and students at the NMMU. New students at universities, and especially first year undergraduates, can sometimes have difficulties in addressing their concerns, questions and ideas about their courses and are faced with the difficulty of adapting to a new lifestyle and the university environment. Interactivity and feedback are key contributors to providing an effective learning environment for such students. Lecturers provide the main source for university students to discover what is expected of them to identify the key learning goals related to a course, from a lecturer (Braxton, Milem & Sullivan, 2000:569). The increase in student numbers in Higher Education over the last decade has been dramatic, placing greater pressures on academic staff in terms of contacting students. As computer technology becomes both more prevalent and more intrusive, its use and misuse are increasingly falling under the critical scrutiny of academic researchers. If traditional educational methods are supported, such support must be flexible enough to accommodate technology, but as a means, not an end. The research of e-mail impact between students and lecturers is still very new and is open for additional study (Braxton, et al. 2000:590).

The purpose of this project is to design, build and implement a secure, payment-based email delivery system that provides privacy and reduces spam.

Although electronic messaging systems (EMS) are an attractive business communication medium several studies on the usage and impact of EMS have shown that despite the benefits, they have been generally used for routine and informal communication activities. Theoretically, EMS have yet to find their niche in organizational communications. Technically, EMS designs are not flexible to support communication activities of managers, are not maintainable to permit easy integration with other office applications and access to information from data/knowledge bases, and are not easily extendible beyond the scope of their initial design. Behaviorally, end users are not directly involved in the development of EMS. This dissertation attempts to bridge the transition of EMS technology from message processing systems to communication support systems. First, the dissertation provides an analysis for a knowledge-based messaging system (KMS) through a framework. The framework provides a theoretical basis to link management theory to EMS technology. It suggests that the communication needs of the managers vary depending on the activity level, implying related variations in EMS functionality. Second, the dissertation provides a design for the KMS through an architecture which incorporates the design and implementation issues such as, flexibility, maintainability, and extendibility. The superimposition of the KMS on an existing EMS provides flexibility, the loose coupling between the KMS-interface components and the KMS-functions increases its maintainability, and the strong functional decomposition and cohesion enhances the extendibility of the system beyond the scope of its initial design. Finally, the dissertation provides a implementation through the development of a prototype KMS which involves users into the design process through a validation study conducted at University of Arizona. The prototype used GDSS tools in eliciting message attributes for the personal knowledge base. This method proved effective in reducing the bottleneck observed in the acquisition of knowledge from multiple experts, simultaneously. Similarly, the combination of observation with interviews proved effective in eliciting the organizational knowledge base. The validation method measured the system's accuracy (which was very accurate) in prioritizing messages for the users.

Thesis (MScIng)--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: Keywords: digital signal processing, OSI layer, network protocols, embedded systems, satellite technology This thesis describes the design and implementation of a rural e-mail system for the Sumbandila satellite. The rural e-mail system was developed during a project sponsored by the Department of Communications of the South African government. The complete Open Systems Interconnect (OSI) layer structure of the protocol architecture used on the satellite hardware and software is described. The equivalent implementation of the OSI layer on the ground station hardware is given. This includes the adaptation of the soundmodem Open Source Software modem to work for the e-mail system’s OSI layer. The design of the Application Layer e-mail system is described and the implementation of this design using the Python, Korn Shell and C programming environments is also given. The procedures used to test the system for reliability and the use of a database to create detailed logs of the e-mail system is shown to have generated a reliable system that is easily maintained. A critical evaluation of the system is provided in the last chapter. / AFRIKAANSE OPSOMMING: Sleutelwoorde: Syferseinverwerking, OSI-lae, netwerkprotokolle, toegewyde stelsels, satelliettegnologie Hierdie tesis beskryf die ontwerp en implementering van ’n plattelandse e-posstelsel vir die Sumbandila satelliet. Die plattelandse e-posstelsel is ontwikkel in opdrag van die Departement van Kommunikasie van die Suid-Afrikaanse regering. Die volledige Open Systems Interconnect (OSI) laagstruktuur van die protokol-argitektuur wat in die satelliet se apparatuur en programmatuur gebruik is, word beskryf. Die ekwivalente implementering van die OSI-laag op die grondstasie-apparatuur word gegee, insluitende die aanpassing van soundmodem, ’n oopbronkode sagteware-modem. Hierdie sagteware-modem word gebruik in die e-posstelsel se fisiese laag. Die ontwerp van die toepassingslaag van die e-posstelsel word beskryf, asook die implementering van hierdie ontwerp met behulp van Python, die Korninterpreteerder en C. Die prosedures waarvolgens stelselbetroubaarheid getoets is, en die gebruik van ’n databasis om noukeurige joernale van e-postransaksies te hou, demonstreer dat ’n betroubare, onderhoubare stelsel gemplementeer is. In die laaste hoofstuk word die stelsel krities geevalueer.

This research examines the role of electronic messaging in business firms. The study presents a taxonomy of electronic mail uses, develops a theoretical framework for analyzing electronic mail impact, and investigates risks and advantages of electronic messaging. The research focus is intermediate-size firms.

Email connects 85% of the world. This paper explores the pattern of information overload encountered by majority of email users and examine what steps key email providers are taking to combat the problem. Besides fighting spam, popular email providers offer very limited tools to reduce the amount of unwanted incoming email. Rather, there has been a trend to expand storage space and aid the organization of email. Storing email is very costly and harmful to the environment. Additionally, information overload can be detrimental to productivity. We propose a simple solution that results in drastic reduction of unwanted mail, also known as graymail.

This dissertation proposes a model supporting the creation of trustable privacies in public online spaces, with the model demonstrating the potential for supporting trustable data handling in the qualitative domain. Privacy and trust, from the pivotal perspective of the individual were identified as crucial intangibles in the qualitative research and personal trust domains. That both privacy and trust depend heavily upon credible mechanisms for privacy became clear during the literature review and interview processes. Privacy, in its many forms, is a concept requiring greatly varying degrees of anonymity, confidentiality and control (Rotenberg, 2001; Lessig, 1998) and this was position was validated by literature and by qualitative comments by academic interviewees. Facilitation of secondary users including academics, public and private organisations, communities, casual information browsers is a goal of this research. This goal of facilitation is supported by the model proposed, and is discussed in Chapter 6, where future work is discussed. The core requirement to address confidentiality, ethics, privacy, ownership and control of data (Corti, 2000) is satisfied by the model as proposed and discussed. Expected outcomes of this research project are summarised as: • Proposed model for the creation of trustable privacies in public spaces. [Primary outcome] • Promotion of collaboration amongst domains and disciplines through improved universal access to archived data [Secondary outcome] • Identification of application domains outside of the initially identified domain set [Secondary outcome]. Self-Contained ReposItory ProcesSIng Template (SCRIPSIT) describes a model supporting a decentralised, trustable set of structures and mechanisms. SCRIPSIT has its eponymous origin in the Latin word scripsit, meaning "he or she wrote". / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2004.

Voice mail has become a major communications tool. This study examined the opinions of 357 Indiana chief executive officers regarding voice mail systems--based on a random sample of the 4,697 members of the Indiana Chamber of Commerce as of November 18, 1992. A 100 percent response rate was achieved. The CEOs generally did not like calling into systems. The study concluded that 20 percent of Indiana businesses have voice mail. The major advantage--as cited by CEOs--to calling into systems was that they can leave detailed messages at anytime. The major disadvantage was that voice mail is cold and impersonal--CEOs want to speak to a real person. The CEOs who have voice mail gave major advantages and disadvantages of their internal systems as well as a rating. Oanparisons were made between various findings including how not having voice mail affects the rating of calling into other systems. / Department of Journalism
