Abstract. Pair programming is one of the more controversial aspects of several Agile system development methods, in particular eXtreme Programming (XP). Various studies have assessed factors that either drive the success or suggest advantages (and disadvantages) of pair programming. In this exploratory study the literature on pair programming is examined and factors distilled. These factors are then compared and contrasted with those discovered in our recent Delphi study of pair programming. Gallis et al. (2003) have proposed an initial framework aimed at providing a comprehensive identification of the major factors impacting team programming situations including pair programming. However, this study demonstrates that the framework should be extended to include an additional category of factors that relate to organizational matters. These factors will be further refined, and used to develop and empirically evaluate a conceptual model of pair programming (success).

The importance of RFID technology is increasing as a means of enhancing productivity and efficiency, and reducing costs. The purpose of this research paper is to study the influence of technological, organizational, environmental, and innovation factors on the adoption of RFID technology by construction companies in Australia. With the growth of Australia's economy, in particular, the construction sector, the logistics departments in construction companies should pay attention to the adoption of more efficient technologies to provide better services for their customers. This paper provides a consolidated framework of RFID technology adoption based on studies on RFID technology adoption in particular from an IS perspective. The paper combines an integrated model of the Technology-Organization-Environment framework, the Diffusion of Innovation theory, and Actor-Network Theory to establish a more comprehensive innovation adoption framework for RFID technology. The data gathered to study the factors affecting the adoption of RFID technology are analysed from the results of a survey of construction companies in Australia, in which 297 Information Technology (IT) staff were participants in this research. The research results show that the factors which had a statistically significant and positive impact on the adoption of RFID services in construction companies were: relative advantage, compatibility, cost, expected benefits, top management support, external support and organization size. The findings from this research study have the potential to provide insights to firms seeking to make investment decisions on the adoption of RFID technology.

In the era of the fourth industrial revolution (Industry 4.0), many Management Information Systems (MIS) integrate real-time data collection and use technologies such as big data, machine learning, and cloud computing, to foster a wide range of creative innovations, business improvements, and new business models and processes. However, the integration of blockchain with MIS offers the blockchain trilemma of security, decentralisation and scalability. MIS are usually Web 2.0 clientserver applications that include the front end web systems and back end databases; while blockchain systems are Web 3.0 decentralised applications. MIS are usually private systems that a single party controls and manages; while blockchain systems are usually public, and any party can join and participate. This paper clarifies the key concepts and illustrates with figures, the implementation of public, private and consortium blockchains on the Ethereum platform. Ultimately, the paper presents a framework for building a private blockchain system on the public Ethereum blockchain. Then, integrating the Web 2.0 client-server applications that are commonly used in MIS with Web 3.0 decentralised blockchain applications.
