Abstract

Abstract: As social computing systems persist over time, many elements such as user experience, perceptions, attitudes and interactions may change. Facebook and Twitter are two social computing systems that have become increasingly popular among universit y students. This research replicated previous studies by Lampe, Ellison and Steinfield (2008), and Johnston, Tanner, Lalla and Kawalski (2013) to assess how Facebook and Twitter use, perception and attitude have changed among university students. Beca use online social networks, social networking sites and micro‑blogging sites are relatively new as areas of academic research, there is limited research into the impacts of these social networking and micro‑blogging sites. A sample of 486 students from th e University of Cape Town (UCT), South Africa completed a survey. The results were then compared to research data from previous studies by Lampe et al. (2008) and Johnston et al. (2013). The results showed that the percentage of students using Face book increased to 95%, Facebook daily usage and the number of Facebook friends doubled from previous surveys. This results also found that the South African students are more dependent on using Facebook, in comparison to using Twitter; that their percep tion of Facebook privacy has led to a decrease in personal information shared on Facebook as well as a change in audience perception. The data also shows that UCT students perceive friends and total strangers to be their main audiences on Twitter; the att itude of UCT students towards Facebook remained positive, on the other hand, a less positive attitude was experienced from the students using Twitter; and Facebook is a more popular method for communication between students. The results clearly highlight the changes in usage, attitude and perception of Facebook over time, and provide a starting point for assessing how usage and attitude to Twitter may change. The results also suggest that should therefore make use of social networking software such as Fac ebook and Twitter both in their personal lives, and in

Abstract

Cost‑effective inventory management includes balancing the cost of inventory with its profit. Most business owners fail to recognize the value of the cost of carrying inventory, which include not only the direct cost of storage, insurance and taxes but also the cost of money tied up in inventory. Running inventory using paper‑based systems, Excel files and traditional enterprise software is a costly and resource‑intensive approach that may not even address the appropriate issues for most businesses. It is with this in mind that this research proposes taking advantage of the Internet of Things (IoT) technology i.e. Radio Frequency Identification (RFID) and Web 2.0 tools in the management of inventory. RFID promotes the communication of things/object through sensors. On the other hand Web 2.0 tools promote the communication of people through their phones or desktop computers. The collaboration of these two technologies could improve inventory management. A comprehensive literature survey is conducted on inventory management functionalities. RFID and Web 2.0 technologies are then mapped to the identified inventory management functionalities. As a result the research proposes inventory management architecture. The paper looks at the architecture of a system that fully integrates the technical advantages of RFID and Web 2.0 tools, such as Twitter for loss prevention and as an enabler for locating misplaced stock, anti‑counterfeiting of stock, and notifications on stock level on the shelve, amongst other applications. The system focuses on enterprises in developing regions in Africa, and South Africa in particular.
