Show moreWhile the scholarship on computer-mediated communication (CMC) can be described as a diverse field of study, with a variety of niche areas and transdisciplinary domains, one of the main recurring research practices within the field involves analytic examinations of digital discourse (Vásquez, 2022). These examinations generally include qualitative and quantitative measures of digital text which is produced, used and re-used in a fast-evolving communicative landscape. Because of the rapid succession of devices, programs and applications that are used for mediation, the methods for analysis sometimes lag behind (as discussed by Herring, 2019). This has raised the question among scholars on how to effectively study and visualise digital discourse, taking into account all affordances and contextual factors that digital resources provide (Car, 2020; Lin, 2015). This paper presents a number of key issues and challenges in the field, bringing together findings from Computer Assisted Language Learning and Learning Analytics studies to provide some new perspectives on CMC text analytics for education.

Show moreScience communication practitioners are always looking for better ways to engage their public. Thisis the case for astronomy communicators, a community of practice that is interested in engaging with thosewho are traditionally out of the science radar, including the less privileged ones. One of the majorchallenges astronomy communicators face when addressing the public is related to knowing what theirinterests are, whether they have and which are their misconceptions and ideas about astronomy, if any.Building strategies to know one’s audience may be decisive for the success of an astronomy communicationpractice, both in formal and informal settings. In this article, we present some of the challenges practitionersmay face when communicating astronomy to today´s audiences and suggest approaches to address them. Show less

Show moreThe growing interest in using zebrafish for genetic and functional dissection of malignancy and infection was highlighted by the second international workshop on Zebrafish Models of Cancer and the Immune Response in Spoleto, Italy ( July 20–22, 2009). The overarching theme of the state-of-the-art reports featured the unique suitability of zebrafish for in vivo monitoring of fundamental biologic and pathologic processes. For example, in vivo imaging was employed for the first demonstration of direct development of hematopoietic stem cells from hemogenic epithelium and for visualization of T-cell homing and interaction with thymic epithelial cells. In addition, in vivo monitoring was instrumental for developing disease models of solid tumors, leukemia, and of inflammatory conditions, and for assessing the efficacy of small molecule drugs under physiologic and pathologic conditions. The success of zebrafish small molecule screens was underscored by the identification of prostaglandin E2 (PGE2) as an efficient inducer of stem cell expansion that led to the initiation of the first human trial on the efficacy of PGE2 in bone marrow transplantation. Further, zebrafish models of infectious diseases such as tuberculosis have been established that are now amenable to high-throughput in vivo drug screens, a much-needed development in the fight against drug-resistant microorganisms. The success of this workshop and the rapidly growing field of cancer and the immune response in zebrafish have spawned follow-up meetings in Boston ( June 2010) and Edinburgh (2011). Show less

Show moreIn many implementations of DNA computing, reliable detection of hybridization is of prime importance. We have applied several well-established DNA mutation scanning methods to this problem. Since they have been developed for speed and accuracy, these technologies are very promising for DNA computing. We have benchmarked a heteroduplex migration assay and enzymatic detection of mismatches on a 4 variable instance of 3SAT, using a previously described blocking algorithm. The first method is promising, but yielded ambiguous results. On the other hand, we were able to distinguish all perfect from imperfect duplexes by means of a CEL I mismatch endonuclease assay.
