In January 2004, the United States Congress passed and put into effect the Controlling the Assault of Non-Solicited Pornography and Marketing Act (CAN SPAM). The Act was set forth to regulate bulk commercial email (spam) and set the limits for what was acceptable. Various sources have since investigated and speculated on the efficacy of the CAN SPAM Act, few of which report a desirable outcome for users of electronic mail. Despite the apparent consensus of anti-spam firms and the community of email users that the Act was less than effective, there is little to no research on the efficacy of the Act that utilizes any significant statistical rigor or accepted scientific practices. The present study seeks to determine what, if any, impact the CAN SPAM act had on spam messages, to identify areas of improvement to help fight spam that is both fraudulent and dangerous. The data consisted of 2,071,965 spam emails sent between February 1, 1998 and December 31, 2008. The data were aggregated by month and an interrupted time series design was chosen to assess the impact the CAN SPAM Act had on spam. Analyses revealed that the CAN SPAM Act had no observable impact on the amount of spam sent and received; no impact on two of three CAN SPAM laws complied with among spam emails, the remaining law of which there was a significant decrease in compliance after the Act; and no impact on the number of spam emails sent from within the United States. Implications of these findings and suggestions for policy are discussed.

This study examines the conditions for successful online mentoring in order to develop writing skills in English in a workplace setting. Chapter 1 gives the background and context of the study. Problems to be addressed in the study and the aims, objectives, hypotheses and their rationale are presented. This is followed by testing procedures, research design, sources of data and research procedures. In Chapter 2, the literature review supports the hypotheses on the need for collaboration in materials development and delivery, mentoring relationships, motivation and computer and Internet efficacy. Chapter 3 presents the findings from the case study bringing into focus problems that would jeopardise a mentoring programme if training providers do not pay attention to the hypotheses. The findings are collated and the hypotheses are confirmed. Conditions for successful online mentoring are spelt out in Chapter 4. The study concludes that online mentoring works once the conditions are properly followed. / English Studies / M.A. (TESOL)

Thesis (LLM)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: The monitoring of electronic communication is likely to face all employers sooner or later. The rapid advancement in technology aimed at helping to monitor electronic communication, makes it easier than ever before for employers to monitor the electronic communications of their employees. There are important questions to consider when dealing with the topic of monitoring electronic communication. Examples include "mayan employer legally monitor electronic communications?" and "how does monitoring affect the employee's right to privacy?" This thesis is an attempt to answer these and other related questions by analysing, inter alia, South African legislation, the Constitution and case law, as well as comparing the law as it applies in the United Kingdom and the United States of America. The analysis and conclusion offered in this thesis aim to provide theoretical consideration to academics and practical application for employers that are faced with the reality of monitoring electronic communications. / AFRIKAANSE OPSOMMING: Alle werkgewers sal waarskynlik die een of ander tyd met die monitering van elektroniese kommunikasie gekonfronteer word. Die snelle voortuitgang in tegnologie wat daarop gemik is om te help met die monitering van elektroniese kommunikasie, maak dit vir werkgewers makliker as ooit tevore om sodanige kommunikasies van hulle werknemers te monitor. Daar is egter belangrike vrae wat oorweeg moet word wanneer die onderwerp van monitering van elektroniese kommunikasie ter sprake kom. Voorbeelde hiervan is "mag 'n werknemer regtens elektroniese kommunikasies monitor?" en "hoe raak monitering die werknemer se reg tot privaatheid?" Hierdie tesis is 'n poging om hierdie en ander verwante vrae te beantwoord deur die ontleding van, onder andere, Suid-Afrikaanse wetgewing, die Grondwet en die reg soos deur hofuitsprake ontwikkel, sowel as vergelyking van die reg soos wat dit van toepassing is in die Verenigde Koninkryk en die Verenigde State van Amerika. Die ontleding en gevolgtrekking wat in hierdie tesis aangebied word, is gemik op die verskaffing van teoretiese oorweging aan akademici en praktiese toepassing vir werkgewers wat met die realiteit van die monitering van elektroniese kommunikasies gekonfronteer word.

Internal marketing and internal communication are essential tools to align em-ployees’ mindsets with the necessary tasks which bring about employee satis-faction and organisational prosperity. Electronic newsletters serve as an internal marketing communication medium which can convey the necessary information to employees regarding the organisation’s goals and objectives. They also act as a medium to build relationships with employees and encourage improved service delivery and customer-oriented employee mindsets. Employees’ willingness to make use of electronic newsletters for the purpose of disseminating organisational information is an indication of employees’ acceptance of the organisational information and use thereof in performing organisational tasks successfully as the organisation intends. The purpose of the current study was to determine employees’ acceptance of electronic newsletters, as an internal marketing communication medium, in order to disseminate organisational information which contributes to the attainment of organisational goals, objectives and success. An empirical study was conducted to determine employees’ acceptance of elec-tronic newsletters by means of an adapted technology acceptance model, self-administered, e-mail survey disseminated to employees of a higher education institution. The study followed a quantitative research approach, utilising re-gression in the analysis of the data. Based on the research results, employees do accept the electronic newsletter for the dissemination of organisational information, albeit with suggestions on how it can be better utilised in future. / Business Management / M.

The motivation of this work is to understand E-shape analysis and how it can be applied to various classification tasks. It has a powerful feature to not only look at what information is contained, but rather how that information looks. This new technique gives E-shape analysis the ability to be language independent and to some extent size independent. In this thesis, I present a new mechanism to characterize an email without using content or context called E-shape analysis for email. I explore the applications of the email shape by carrying out a case study; botnet detection and two possible applications: spam filtering and social-context based finger printing. The second part of this thesis takes what I apply E-shape analysis to activity recognition of humans. Using the Android platform and a T-Mobile G1 phone I collect data from the triaxial accelerometer and use it to classify the motion behavior of a subject.

The aim of this research is to shed more light on an aspect identified as a gap in knowledge in the literature; the use of a social networking service as knowledge sharing platform. More specifically, this research sets out to establish if the social networking service Twitter could be used as knowledge-sharing platform in small South African businesses in the Western Cape. A mixed method research design is used. This includes gathering data through questionnaires as well as conducting semi-structured interviews for case study participants. The sample comprises 122 questionnaire participants together with 14 semi-structured interview participants across three small businesses located in the Western Cape Province. Although it is apparent from the study conducted that small businesses are not yet willing to forego traditional platforms such as Email to use Twitter exclusively as a knowledge sharing tool, the researcher proposes a case for using Twitter, which he believes, could take the most advantage of the functions Twitter brings to a small business operation. / School of Computing / M.

This study aims to explore politeness shown by lecturers during tuition and student support conversations with the objective of promoting polite interactions between IsiZulu mother tongue and non-mother tongue speakers in higher education in South Africa. In particular, the study investigates the way in which politeness in email communication influences learning outcomes within an ODL environment, using quantitative and qualitative research methodologies, a questionnaire as well as interviews to collect data from a cross-section of students from an Open Distance Learning (ODL) institution. All the results drawn from the data sources, namely the questionnaires and interviews, were enumerated according to the data collection tools used. Version 12 of SPSS and Nvivo were used to analyse the quantitative data. The analysis is also based on the politeness strategies of Brown and Levinson (1978) as well as a conceptual framework that links all the variables. Based on the results, the research hypotheses are accepted, thus indicating that politeness in email communication influences learning outcomes within an ODL environment. In particular, the results show that, overall, lecturers who employ politeness contribute positively to student compliance. Accordingly, the study recommends that ODL should recognise both the role of language in communication as well as the power and influence of politeness in communication. / African Languages / D.
