The aim of the study was to determine the relative effectiveness of a motivational-targeted (MT) message intervention designed to increase physical activity (PA) in cardiac patients beginning a long-term maintenance cardiac rehabilitation (CR) program to enable them to meet recommended PA levels. Methods: Fifty two individuals (34 males, 18 females) volunteered for the study and were randomly assigned to either the Usual Care Group (UC), or the Motivational Message Group (MM). Participants in the MM group received, in addition to the usual long-term maintenance CR program, 12 –standard, MT newsletters at the beginning of each week during the intervention period. Thirty-three individuals (mean age: 61.4 ± 11.4 years) completed the study with viable data. PA was assessed for 12 weeks with the use of a Lifecorder PLUS accelerometer. Baseline and post measures of weight, body mass index (BMI), body fat percentage, resting heart rate and blood pressure measures, and fasting blood measures were completed on all subjects. Subjects also completed an exercise self-efficacy questionnaire and a stage of change of physical activity readiness questionnaire at these timeframes. Results: Independent sample t-tests indicated there were no significant differences between baseline characteristics between the UC group and MM group. Results indicated slight increases in the MM group in steps/day, and moderate-vigorous minutes/day, with slight decreases in resting heart rate, blood pressure, and blood lipid values compared to the UC group. Two-way repeated measures ANOVA tests determined there was a significant main effect for time for resting heart rate, however, there were no other significant differences between the two groups or within either group, showing no time by group interaction for any variables measured. Conclusions: MT messages may have the ability to increase PA levels and adherence in CR patients, however, more research is needed to determine the significant value of motivational-targeted messages for these individuals. / School of Physical Education, Sport, and Exercise Science

The research is based on a case study of an internal newsletter, Platform. The objective was to obtain more information about Transnet Freight Rail employees‘ thoughts on its effectiveness and the effectiveness of internal newsletters by using Platform as an example. The treatise explored the perceptions of employees and Transnet in terms of the effectiveness of the internal newsletter as a communication tool as well as their attitudes towards the newsletter as an information disseminating medium. A mixed methods approach was used for analysis in this study. The first methodological paradigm took an interpretivist approach, focusing primarily on analysing the content of the newsletter. The second methodological design was based on the positivistic theory approach and utilised a survey by questionnaire. One hundred and twenty (120) questionnaires were issued to Transnet Freight Rail employees representing the three regions: Central Region, Eastern Region & Western Region and the Head Office of which 120 (100 percent) were received back by the deadline. Of these respondents 56 (46,66 percent) said that they find Platform very relevant as an internal newsletter. A further finding was that 68,33 percent of the respondents said Platform should stay as it is. About 58,33 percent of the respondents took 30 minutes to an hour to read the newsletter with ratings of 72,5 percent interested in communication from management, 65 percent in financial performance, 60 percent in news about people and 59,16 percent in departmental information. The main types of information required are about updates on business performance and safety news. The content of six editions of the newsletter was analysed. The newsletter editions used were from the latest one published counting backwards. The content of the newsletter varies in each edition and depends on the theme. There are similar themes that come up with every edition such as safety. The style of writing used is simple to ensure maximum understanding.

The research addresses three research questions in this study: (1) What kinds of information are included in employee newsletters?; (2) What are the sender’s purposes?; (3) Is there a relationship between employee newsletter content and the sender’s purposes? An analysis of relevant literature will help in the development of our knowledge of employee newsletters. The review of literature that follows in Chapter 2 also will identify factors that have led to the popularity of the newsletter as a means of internal communication
