Mobile Payment wird heiß diskutiert, allerdings liegt die Nutzung insbesondere beim Einkauf deutlich hinter den Erwartungen. Anders in China, wo das Thema fest etabliert und durch China UnionPay zentral abgewickelt wird. In Deutschland gibt es zahlreiche Ansätze unterschiedlicher Partner des Mobile Payment Ökosystems, die sich unterschiedlicher technischer Verfahren zum Zahlungsaustausch bedienen. Beim Konsument ist das Thema bereits angekommen, doch Unwissenheit über die Technik, Angst vor Datenmissbrauch und fehlende Informationen dominieren. Grundsätzlich sind Konsumenten nicht abgeneigt, solange die Nutzung ihnen echte Vorteile bringt – und die Sicherheit gewährleistet ist.
Mobile payment is hotly debated, but the use is still below expectations – especially in shopping environment. In China the topic is already well established, not only because it is managed centrally by China UnionPay. In Germany numerous approaches can be found using different technical methods of payment exchange. Consumers are aware of the ability to pay via mobile phone. But ignorance about the technologies, fear of data misuse and lack of information prevent a further spread. But consumers can be encouraged by offering a real benefit and the guarantee of safety.

"This book reviews recent studies into smartphones and the news, and argues that the greatest impact on news of the smartphone as a dominant technological artefact is to shift it away from an authoritative, fixed 'first draft of history' to become a fluid, flexible stream of information from which each individual constructs their own meaning. The news has taken on a new life, fragmented by five billion smartphones, disrupting not just an industry but also the consequence of the news in societies worldwide. This book considers how the smartphone has changed the production of journalism through contributions from the general public, the dominance of visual over textual media, the shift towards brevity, the challenges of verification, and the possibilities offered by the multi-skilled mobile journalist, or MoJo. The book looks at the manner in which news is promoted and distributed via smartphones, specifically its place on social media. Finally, it considers how news-on-smartphones fits into consumers' lives, and how their use of the smartphone to access news is impacting back on its production. This is an insightful research text for journalism students and scholars with an interest in digital journalism, new media, and the intersection between technology and communication"--

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.

Sl Se c'è una cosa che abbiamo sempre, letteralmente, sotto il naso, è lo smartphone. Ed è normale credere, dunque, che sappiamo cosa sia. Ma è davvero così? Per scoprirlo, 11 antropologi hanno trascorso 16 mesi in varie comunità in Africa, Asia, Europa e Sud America per osservare il modo in cui gli anziani utilizzano lo smartphone, e la loro ricerca ha rivelato che si tratta di una tecnologia rivolta a tutti, non solo ai giovani. Lo Smartphone Globale presenta i risultati frutto di questo progetto di ricerca comparativa di respiro globale. Gli smartphone sono diventati tanto un luogo in cui viviamo, quanto un dispositivo di 'opportunismo perpetuo' da cui non ci separiamo mai. Gli autori hanno dimostrato che lo smartphone è molto più di un 'contenitore di app', concentrandosi sulle differenze tra ciò che le persone dicono sugli smartphone e il modo in cui li usano. Nessun dispositivo aveva mai raggiunto un tale livello di 'trasformabilità' – trasformabilità che si concretizza nella capacità di assimilare rapidamente i nostri valori personali. Per poterlo comprendere, dunque, dobbiamo tener presente un'ampia gamma di sfumature nazionali e culturali, quali la comunicazione visiva in Cina e Giappone, i trasferimenti di denaro sotto forma di credito telefonico in Camerun e in Uganda, e l'accesso a informazioni mediche in Cina e Irlanda, oltre alle diverse traiettorie della terza età ad Al Quds, in Brasile e in Italia. Solo allora potremo sapere davvero cos'è uno smartphone e capire appieno l'impatto che ha sulla vita delle persone in tutto il mondo.

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.

Part 3: Mobile Device Forensics ; International audience ; Humans tend to use specific words to express their emotional states in written and oral communications. Scientists in the area of text mining and natural language processing have studied sentiment fingerprints residing in text to extract the emotional polarity of customers for a product or to evaluate the popularity of politicians. Recent research focused on micro-blogging has found notable similarities between Twitter feeds and SMS (short message service) text messages. This paper investigates the common characteristics of both formats for sentiment analysis purposes and verifies the correctness of the similarity assumption. A lexicon-based approach is used to extract and compute the sentiment scores of SMS messages found on smartphones. The data is presented along a timeline that depicts a sender's emotional fingerprint. This form of analysis and visualization can enrich a forensic investigation by conveying potential psychological patterns from text messages.

"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)
