This issue is our third Students, Transitions, Achievement, Retention and Success (STARS) Conference special issue held in July this year in Adelaide, Australia.   As is customary, this issue of the journal publishes the top research papers selected via a peer review process and the top Emerging Initiatives selected by the Conference Committee.    We are delighted to feature in this special  issue —Reflections on Student Persistence—prepared by Advisory Board member Professor Vincent Tinto, Distinguished University Professor Emeritus at Syracuse University, USA.  Vincent is a long-time friend and supporter of STARS and its predecessor FYHE Conferences and Journal.   In his article, Vincent explores the case for motivation to be considered as a significant aspect of the tertiary student psyche by drawing on theoretical frameworks, research and practical experiences related to the issue.


For a long time, ELT (‘English language teaching’) scholars and practitioners have used terms like ‘ESL’ (‘English as a second language’) and ‘EFL’ (‘English as a foreign language’) unquestioningly to describe the English used by people outside the so-called ENL (‘English as a native language’) circle. For example, ELT practitioners may conveniently refer to students from places like China, Vietnam and Thailand as EFL students. Interestingly, we find counterparts of such terms in ‘World Englishes’ studies; Braj Kachru’s ‘Inner Circle English’, ‘Outer Circle English’ and ‘Expanding Circle English’ essentially refer to ENL ESL and EFL respectively. Despite the popularity of such terms in scholarly circles, the problems associated with their use have not often been explored in depth. Nevertheless, some authors have described such problems. For example, commenting on the distinction between ESL and EFL, Nayar (1997, p. 10) states, “a great deal of referential fuzziness within the two and denotative overlap between the two are making the terminological distinctions unclear, impractical, and ineffective or, worse still, in some cases inauspicious and irrelevant.” This special issue aims to further examine the use and relevance of these terms.

Abstract Recent years have witnessed an expanding body of scholarship indicating the importance of slave trade and slavery in different parts of the Indian Ocean and Indonesian archipelago worlds. This work has not only challenged the dominant focus of slavery scholarship on the Atlantic context but has also encouraged scholars to reassess wider perspectives on Asian and global social histories. This special issue brings together contributions that explore these new horizons. Together, they take up the issue of slavery and mobility in different parts of the Indian Ocean and Indonesian archipelago worlds from a comparative perspective, dealing not only with the existence and patterns of slave trade itself but also with its social and sociopolitical implications. These articles require us to rethink some of the dominant perspectives in a historiography that for a long time has emphasized the unique and local character of “Asian” slaveries, positing dichotomies between slavery in the Atlantic and elsewhere, as well as between Western and non-Western slaveries. The contributions to this special issue challenge several of these existing dichotomies and provide new contributions to the understanding of the role and importance of slavery from a global perspective, as well as to the history of the Indian Ocean and Indonesian archipelago worlds. This introduction reflects on this collective contribution and aims to provide an outline for a relevant research agenda.

This article showcases an interview conducted with Dr. Joe Freidhoff, Executive Director of the Michigan Virtual Learning Research Institute, specifically for this special issue of the OLC Online Learning Journal. The perspectives provided by Dr. Freidhoff on the ever-changing field of K-12 online learning served two purposes: to introduce long-time profession-based journal readership to the field of K-12 online learning and to provide K-12 online learning scholars with perspective and direction for meeting the current and future needs of K-12 stakeholders.

For a long time, the tight junction (TJ) was known to form and regulate the paracellular barrier between epithelia and endothelial cell sheets. Starting shortly after the discovery of the proteins forming the TJ—mainly, the two families of claudins and TAMPs—several other functions have been discovered, a striking one being the surprising finding that some claudins form paracellular channels for small ions and/or water. This Special Issue covers numerous dedicated topics including pathogens affecting the TJ barrier, TJ regulation via immune cells, the TJ as a therapeutic target, TJ and cell polarity, the function of and regulation by proteins of the tricellular TJ, the TJ as a regulator of cellular processes, organ- and tissue-specific functions, TJs as sensors and reactors to environmental conditions, and last, but not least, TJ proteins and cancer. It is not surprising that due to this diversity of topics and functions, the still-young field of TJ research is growing fast. This Editorial gives an introduction to all 43 papers of the Special Issue in a structured topical order.
