A review of the empirical studies of computer supported human-to-human communication
This paper presents a review of the empirical studies of human-to-human communication which have been carried out over the last three decades. Although this review is primarily concerned with the empirical studies of computer supported human-to-human communication, a number of studies dealing with group work in non-computer-based collaborative environments, which form the basis of many of the empirical studies of the recent years in the area of CSCW, are also discussed. The concept of person and task spaces is introduced and then subsequently used to categorise the large volume of studies reported in this review. This paper also gives a comparative analysis of the findings of these studies, and draws a number of general conclusions to guide the design and evaluation of future CSCW systems
Tarski's influence on computer science
The influence of Alfred Tarski on computer science was indirect but
significant in a number of directions and was in certain respects fundamental.
Here surveyed is the work of Tarski on the decision procedure for algebra and
geometry, the method of elimination of quantifiers, the semantics of formal
languages, modeltheoretic preservation theorems, and algebraic logic; various
connections of each with computer science are taken up
Are you Charlie or Ahmed? Cultural pluralism in Charlie Hebdo response on Twitter
We study the response to the Charlie Hebdo shootings of January 7, 2015 on
Twitter across the globe. We ask whether the stances on the issue of freedom of
speech can be modeled using established sociological theories, including
Huntington's culturalist Clash of Civilizations, and those taking into
consideration social context, including Density and Interdependence theories.
We find support for Huntington's culturalist explanation, in that the
established traditions and norms of one's "civilization" predetermine some of
one's opinion. However, at an individual level, we also find social context to
play a significant role, with non-Arabs living in Arab countries using
#JeSuisAhmed ("I am Ahmed") five times more often when they are embedded in a
mixed Arab/non-Arab (mention) network. Among Arabs living in the West, we find
a great variety of responses, not altogether associated with the size of their
expatriate community, suggesting other variables to be at play.Comment: International AAAI Conference on Web and Social Media (ICWSM), 201
