Networked knowledge: challenges for teacher education [Editorial]

Since 1990, the World Wide Web has caused an inversion in the information economy of education. Where a traditional view of education characterized teachers as dispensers of knowledge, the second half of the twentieth century witnessed a shift towards an alternative paradigm in which knowledge is viewed as constructed by the learner from personal and shared experience. In an information-rich environment, education is likely to be less about accumulating information and more about transforming it in ways that make it more useful. Although the evolution of a networked knowledge economy may eventually require responses in many aspects of education, at least three areas are already evident. These are questions of knowledge as property attaching to concepts such as copyright and plagiarism, development of processes and skills for effective collaboration, and the problem of assessment of student learning if it is accepted that knowledge may exist in the network rather than the individual

There is no finite-variable equational axiomatization of representable relation algebras over weakly representable relation algebras

We prove that any equational basis that defines RRA over wRRA must contain infinitely many variables. The proof uses a construction of arbitrarily large finite weakly representable but not representable relation algebras whose "small" subalgebras are representable.Comment: To appear in Review of Symbolic Logi

The Influence of Resonant Leadership Styles on Employee Engagement Within a Financial Services Organization

Researchers suggest that job dissatisfaction in the United States is escalating rapidly. This is due in part to current economic issues but also to a growing disconnect between managers and employees. A recent study found that less than half of all employees are happy at work--the lowest satisfaction ratings in 22 years (Neal, 2010). This action research project focuses on one business line within a large international financial services organization and examines the relationship between resonant leadership styles and employee engagement. Internal surveys and interviews were conducted to establish a baseline understanding of organizational concepts including: Emotional intelligence, Resonant Leadership, Employee Engagement and Executive Coaching. I argue that a leader\u27s ability to create and sustain emotional connections with employees, while at the same time demonstrating mindfulness, hope and compassion may result in: higher job satisfaction, increased levels of trust, a heightened sense of optimism, and greater overall team member engagement

Publishing data evidence to support educational technology claims [Editorial]

As is evident by this issue, JTATE publishes works that include rich data evidence, regardless of the method used in the research design. Detailed and careful research analyses, as well as purposeful design and construction of the write-up are critical to building a strong foundation of educational technology literature. Researchers in educational technology and technology and teacher education more specifically, who decide to follow a platinum standard for research publication, are strengthening and broadening the credibility of a relatively young field. The JTATE editors promote this line of thinking, encouraging editorial board members, reviewers, and authors to assist with this important goal
