- Description: The worldwide popularity of social networking sites (SNSs) and the technical features they offer users have created many opportunities for malicious individuals to exploit the behavioral tendencies of their users via social engineering tactics. The self-representation and social interactions on SNSs encourage users to reveal their personalities in a way which characterises their behaviour. Frequent engagement on SNSs may also reinforce the performance of certain activities, such as sharing and clicking on links, at a “habitual” level on these sites. Subsequently, this may also influence users to overlook phishing posts and messages on SNSs and thus not apply sufficient cognitive effort in their decision-making. As users do not expect phishing threats on these sites, they may become accustomed to behaving in this manner which may consequently put them at risk of such attacks. Using an online survey, primary data was collected from 215 final-year undergraduate students. Employing structural equation modelling techniques, the associations between the Big Five personality traits, habits and information processing were examined with the aim to identify users susceptible to phishing on SNSs. Moreover, other behavioural factors such as social norms, computer self-efficacy and perceived risk were examined in terms of their influence on phishing susceptibility. The results of the analysis revealed the following key findings: 1) users with the personality traits of extraversion, agreeableness and neuroticism are more likely to perform habitual behaviour, while conscientious users are least likely; 2) users who perform certain behaviours out of habit are directly susceptible to phishing attacks; 3) users who behave out of habit are likely to apply a heuristic mode of processing and are therefore more susceptible to phishing attacks on SNSs than those who apply systematic processing; 4) users with higher computer self-efficacy are less susceptible to phishing; and 5) users who are influenced by social norms are at greater risk of phishing. This study makes a contribution to scholarship and to practice, as it is the first empirical study to investigate, in one comprehensive model, the relationship between personality traits, habit and their effect on information processing which may influence susceptibility to phishing on SNSs. The findings of this study may assist organisations in the customisation of an individual anti-phishing training programme to target specific dispositional factors in vulnerable users. By using a similar instrument to the one used in this study, pre-assessments could determine and classify certain risk profiles that make users vulnerable to phishing attacks. , Thesis (PhD) -- Faculty of Commerce, Information Systems, 2021

- Description: This study examined the use of Social Media/Web 2.0 for research support and it is guided by three objectives namely: a) to ascertain the uses of social media in academic institutions; b) to identify the challenges associated with social media use for research purposes and c) to provide experiences of social media application in selected African academic institutions. The study makes use of literature analysis in combination with personal and professional work experiences on the use of social media from librarians in four different countries. Institutional experiences of the four librarians showed that it is only Rhodes University Library that uses social media in its library, which is as a result of a formal social media strategy. For the other three universities, University of Education, Winneba Library in Ghana, Makerere University Library in Uganda and the University of Nigeria Library, the use of social media is not encouraging. They use it mostly for communication and interaction with colleagues. It was also discovered that there is no social media strategy available in these university libraries. Based on these findings, the study recommended the implementation of a social media strategy, appointment of social media librarians in these libraries, and continuing professional development of librarians to keep abreast with current trends. Web 2.0/Social Media is a new technology offering new options for African academic librarians in their research support role

Self-efficacy and social support of academy cricketers

- Description: Self-efficacy is considered to be a significant variable for enhancing all aspects of human performance (Druckman, 2004). Social support may influence self-efficacy through each of the four channels of self-efficacy information which consist of performance accomplishments, vicarious experience, verbal persuasion and physiological responses (Bandura, 1997). The primary aim of this study was to explore and describe the nature of change that occurred in selfefficacy and received social support of university-age academy cricketers over the duration of an academy programme. The secondary aim was to explore and describe the relationship between the two constructs, self-efficacy and social support. Sixty-five male, university-age (18-25 years) provincial academy cricketers completed a social support measure and a self-efficacy measure specifically designed for the purposes of this study. These measures were based on Rees and Freeman’s (2007) items and Cox, Martens and Russell’s (2003) revised Competitive State Anxiety Inventory-2 (CSAI-2 - Martens, Burton, Vealey, Bump & Smith, 1990) respectively. The perceived pre- and post-academy personal ratings of self-efficacy and social support, obtained prior to the start of the South African Interprovincial Academy Cricket week, referred to participants’ perceptions before and after attending their respective provincial academies. An inferential pre-experimental post-pretest design was used. The results included significant changes found in self-efficacy, esteem social support, informational social support and tangible social support over the academy season. There were no differences attributed to the length of time a cricketer had spent at the academy or to the cricketer’s highest level of achievement in cricket. The only significant correlation that existed between self-efficacy and social support was the correlation between self-efficacy and x informational social support. This study provided an initial insight into the role of self-efficacy and social support in talented cricketers, especially in a South African context.
