Science,technology and purpose

In a recent book, ‘Machines with a Purpose’, many of the unattractive features of our technology were traced to a view of the world which has predominated in science for nearly four hundred years. This is, that nature, and everything that it contains, operates causally and without purpose. To counter this view, an alternative, purposive view was developed. The paper gives a simple account of this development, of other related work, and of the underlying motivation.     

Web evolution and Web Science

This paper examines the evolution of the World Wide Web as a network of networks and discusses the emergence of Web Science as an interdisciplinary area that can provide us with insights on how the Web developed, and how it has affected and is affected by society. Through its different stages of evolution, the Web has gradually changed from a technological network of documents to a network where documents, data, people and organisations are interlinked in various and often unexpected ways. It has developed from a technological artefact separate from people to an integral part of human activity that is having an increasingly significant impact on the world. This paper outlines the lessons from this retrospective examination of the evolution of the Web, presents the main outcomes of Web Science activities and discusses directions along which future developments could be anticipated.     

Software Science and Cognitive Psychology

Halstead proposed a methodology for studying the process of programming known as software science. This methodology merges theories from cognitive psychology with theories from computer science. There is evidence that some of the assumptions of software science incorrectly apply the results of cognitive psychology studies. HAlstead proposed theories relative to human memory models that appear to be without support from psychologists. Other software scientists, however, report empirical evidence that may support some of those theories. This anomaly places aspects of software science in a precarious position. The three conflicting issues discussed in this paper are 1) limitations of short-term memory and number of sub-routine parameters, 2) searches in human memory and programming effort, and 3) psychological time and programming time.     

Science of Scientific Team Science: A survey

Scientific teamwork collaboration is an integral element of the scientific process that often leads to significant findings. Systematic analysis of scientific teamwork collaboration continues to influence both the advance in science and knowledge production. This paper presents an overview of Science of Scientific Team Science (SSTS). SSTS explores the behaviors and attributes of teamwork and team-based collaboration specific to scientific teams from the perspective of quantitative analysis, which refers to a branch of science that analyzes and discovers scientific collaboration patterns inter- or extra-team. Aiming at assisting scientific team formation, improving collaboration environment, evaluating team performance, and fostering collaborative behaviors, this survey presents an overview in SSTS. Theoretical background of SSTS at different team development stages has been discussed. In addition, three classifications of SSTS, including interdisciplinary, multidisciplinary, and transdisciplinary research approaches have been investigated. Their associated similarities and differences, challenges and benefits, are also examined. This paper also summarizes web-based tools that enhance one’s understanding and opinion of SSTS. Key technologies and open issues are then discussed. The association among scientific collaboration, scientific teamwork, SSTS, and cross-disciplinary research gives rise to critical implications for scholars who wish to employ and invest in those issues.
