Abstract
Smartphone ads compete for the user's attention, which is initially intended to focus on other areas of the small
screen of the device. Despite this competition, smartphone advertisements aim to produce as much cognitive reward as possible in
exchange for the mental effort expended in their processing, that is, they aim at the audience's relevance, as claimed by
relevance theory (Sperber and Wilson 1995), a theory in which cyberpragmatics (Yus 2011) is rooted. This paper addresses several key qualities of effective smartphone
advertising from a cyberpragmatics perspective that focuses on possible sources of relevance of online communication, and now
applied to smartphone ads. Furthermore, it is claimed that today's smartphone-based advertising cannot be accounted for
pragmatically without the incorporation of key terms such as contextual constraint and non-propositional
effect, which add to more traditional pragmatic accounts of online communication (Yus 2017a, 2021a).

In 2015, most censorship takes place online: South Korea has the highest broadband Internet penetration in the world. The KCSC employs an army of energetic censors across a number of bureaux, each assigned a different branch of the media or cyberspace, to manage what its people can view--always a moving target. Borowiec explores South Korea's new law that embeds surveillance tool on teenagers' smartphones. Adapted from the source document.

Filter questions are used to administer follow-up questions to eligible respondents while allowing respondents who are not eligible to skip those questions. Filter questions can be asked in either the interleafed or the grouped formats. In the interleafed format, the follow-ups are asked immediately after the filter question; in the grouped format, follow-ups are asked after the filter question block. Underreporting can occur in the interleafed format due to respondents' desire to reduce the burden of the survey. This phenomenon is called motivated misreporting. Because smartphone surveys are more burdensome than web surveys completed on a computer or laptop, due to the smaller screen size, longer page loading times, and more distraction, we expect that motivated misreporting is more pronounced on smartphones. Furthermore, we expect that misreporting occurs not only in the filter questions themselves but also extends to data quality in the follow-up questions. We randomly assigned 3,517 respondents of a German online access panel to either the PC or the smartphone. Our results show that while both PC and smartphone respondents trigger fewer filter questions in the interleafed format than the grouped format, we did not find differences between PC and smartphone respondents regarding the number of triggered filter questions. However, smartphone respondents provide lower data quality in the follow-up questions, especially in the grouped format. We conclude with recommendations for web survey designers who intend to incorporate smartphone respondents in their surveys.

"This paper shows that computer users and smartphone users taking part in a web survey optimized for smartphones give responses of almost the same quality. Combining a design of one question in each page and innovative page navigation methods, we can get high quality data by both computer and smartphone users. The two groups of users are also compared with regard to their precisely measured item response times. The analysis shows that using a smartphone instead of a computer increases about 20% the geometric mean of item response times. The data analyzed in this paper were collected by a smartphone-friendly web survey. All question texts are short and the response buttons are large and easy to use. As a result, there are no significant interactions between smartphone use and either the length of the question or the age of the respondent. Thus, the longer response times among smartphone users should be explored in other causes, such as the likelihood of smartphone users being distracted by their environment." (author's abstract)

This paper focuses on the blurring boundary between the "human self" and the smartphone, using interviews with 60 heavy smartphone users. The interview responses reveal three types of self-extension via the smartphone— functional extension, anthropomorphic extension, and ontological extension. Smartphone users assert that their phone has become an indispensable part of their self and thus influences their identity and sense of being in both positive and negative ways.
