Dear Readers,
It is a great pleasure to introduce the fifth and last regular issues
of 2019. With another year of great interest indicated by downloads
and reads as well as good impact numbers, we are looking very positive
in the year 2020. Beginning with the first issue in 2020 we will now
apply our new open content strategy to provide even more value for
authors, readers and the wider research community. All of these
achievements would not be possible without the generous support by the
members of our consortium, our active and decicated editorial board,
the J.UCS team and most importantly the contributions by the
authors. I would therefore like to thank all of you and look forward
to further collaborations in the new year. I would also like to
further extend our editorial board: if you are a tenured Associate
Professor or above with a good publication record, please do apply for
a membership in our editorial board. We are also interested in high
quality proposals of special issues covering emerging topics and new
trends. If you are interested, send your proposal to me at
c.guetl@tugraz.at.
In this regular issue, I am very happy to introduce 5 accepted papers
from 8 different countries.
George-Petru Ciordas-Hertel, Jan Schneider, Stefaan Ternier and
Hendrik Drachsler from Germany report on their structured literature
review and propose an approach towards a trusted and interoperable
learning analytics infrastructure.
In a collaborative research between Spain and Mexico, Pedro G. Espejo,
Eva Gibaja, Víctor H. Menéndez, Alfredo Zapata and Cristóbal Romero
propose an improved approach towards automatically learning object
categorization by taking into consideration information of learning
object usage and considering multiple categories by apply a
multi-label learning approach.
Andreas Hinderks, Dominique Winter, Martin Schrepp and Jörg
Thomaschewski elaborate in their collaborative research between Spain
and Germany the analysis and applicability of user experience and
usability questionnaires.
Further, in a collaborative work between Spain and Italy, J. David
Patón-Romero, Maria Teresa Baldassarre, Moisés Rodríguez and Mario
Piattini develop and assess a governance and management framework for
green IT that may guide to gradually implement, evaluate, and improve
all those aspects and characteristics of governance and management
that constitutes the basis of the processes, practices, and activities
of Green IT.
Estêvão B. Saleme, Celso A. S. Santos, Ricardo A. Falbo, Gheorghita
Ghinea and Frederic Andres propose in their collaborative research
between Brazil, Uk and Japan to establish a common conceptualization
about mulsemedia systems and to support the design process through a
domain reference ontology named MulseOnto which also has been verified
and validated.
Enjoy reading!
Cordially,
