A History of Cluster Analysis Using the Classification Society's Bibliography Over Four Decades
The Classification Literature Automated Search Service, an annual
bibliography based on citation of one or more of a set of around 80 book or
journal publications, ran from 1972 to 2012. We analyze here the years 1994 to
2011. The Classification Society's Service, as it was termed, has been produced
by the Classification Society. In earlier decades it was distributed as a
diskette or CD with the Journal of Classification. Among our findings are the
following: an enormous increase in scholarly production post approximately
2000; a very major increase in quantity, coupled with work in different
disciplines, from approximately 2004; and a major shift also from cluster
analysis in earlier times having mathematics and psychology as disciplines of
the journals published in, and affiliations of authors, contrasted with, in
more recent times, a "centre of gravity" in management and engineering.Comment: 23 pages, 9 figure
What Drives Students' Loyalty-Formation in Social Media Learning Within a Personal Learning Environment Approach? The Moderating Role of Need for Cognition
Our study analyzes an educational experience based on the integrated use of social media within a higher education course under a personal learning environment approach and investigates the factors that determine students' loyalty to social media learning. We examined the moderating role of need for cognition (NFC) in students' formation of attitudes, satisfaction, and loyalty toward this learning experience. The results indicate that NFC has an influence on these variables, significantly moderating how loyalty toward social media learning is formed. For high-NFC students, satisfaction with the learning experience is the most important variable to explain loyalty; whereas for low-NFC students, attitudes have a stronger effect. Different strategies are suggested, according to the learners' NFC levels, for increasing the use of social media in personal learning environments. Practical implications for improving the integration of such informal resources into formal education are discussed.Junta de AndalucĂa – Programa Andaluz de I + D P12 SEJ 259
