  • The Effects of Content Likeability, Content Credibility
    Journal of Theoretical and Applied Electronic Commerce Research This paper is available online at ISSN 0718–1876 Electronic Version www.jtaer.com VOL 15 / ISSUE 3 / SEPTEMBER 2020 / 1-19 DOI: 10.4067/S0718-18762020000300102 © 2020 Universidad de Talca - Chile The Effects of Content Likeability, Content Credibility, and Social Media Engagement on Users’ Acceptance of Product Placement in Mobile Social Networks Ivan Ka Wai Lai 1 and Yide Liu 2 1 City University of Macau, Faculty of International Tourism and Management, Taipa, Macau, [email protected] 2 Macau University of Science and Technology, School of Business, Taipa, Macau, [email protected] Received 29 August 2018; received in revised form 11 June 2019; accepted 1 October 2019 Abstract Nowadays, product placements are commonly presented on mobile social media but related studies are rare. The main purpose of the study is to investigate the effects of content likeability, content credibility, and social media engagement on users’ acceptance of product placement in mobile social networks. The results of the online survey indicate that content likeability is an antecedent of social media engagement and content credibility; social media engagement has an influence on content credibility; and content likeability, content credibility, and social media engagement both directly affect user acceptance of product placement in mobile social networks. Furthermore, social media engagement has an interaction effect with content likeability on the content credibility of mobile social networks. The results of the multi-group analysis indicate that young adults show differences with middle-aged adults in the direct effect of content likeability on social media engagement and in the interaction effect of content credibility and social media engagement on the acceptance of product placement in mobile social networks.

Juni 2018 Berlin 2018 iii A Bill of Rights for Users of the Social Web Authored by Joseph Smarr, Marc Canter, Robert Scoble, and Michael Arrington1 September 4, 2007 Preamble: There are already many who support the ideas laid out in this Bill of Rights, but we are actively seeking to grow the roster of those publicly backing the principles and approaches it outlines. That said, this Bill of Rights is not a document “carved in stone” (or written on paper). It is a blog post, and it is intended to spur conversation and debate, which will naturally lead to tweaks of the language. So, let’s get the dialogue going and get as many of the major stakeholders on board as we can! A Bill of Rights for Users of the Social Web We publicly assert that all users of the social web are entitled to certain fundamental rights, specifically: Ownership of their own personal information, including: • their own profile data • the list of people they are connected to • the activity stream of content they create; • Control of whether and how such personal information is shared with others; and • Freedom to grant persistent access to their personal information to trusted external sites.

  • Subscribing Via Google Reader to RSS Feeds & Classroom Blogs
    Subscribing Via Google Reader to RSS Feeds & Classroom Blogs All of our classrooms at MJGDS have their own blog. Several grade levels are piloting individual student portfolios based on a blogging platform. • How do you keep up with all this information? • How do you filter and organize it? • How can you avoid having to go back to blogs to check if the owner has updated with a new post? The RSS feed comes to the rescue! According to Wikipedia RSS is defined as: “RSS (most commonly expanded as Really Simple Syndication) is a family of web feed formats used to publish frequently updated works—such as blog entries, news headlines, audio, and video—in a standardized format. An RSS document (which is called a "feed", "web feed", or "channel") includes full or summarized text, plus metadata such as publishing dates and authorship. Web feeds benefit publishers by letting them syndicate content automatically. They benefit readers who want to subscribe to timely updates from favored websites or to aggregate feeds from many sites into one place. RSS feeds can be read using software called an "RSS reader", "feed reader", or "aggregator", which can be web-based, desktop-based, or mobile-device-based.” Licensed under Creative Commons Subscribe via RSS Google Reader to Classroom Blogs. Silvia Rosenthal Tolisano~ Langwitches Blog~ Globally Connected Learning Consultant Subscribing Via Google Reader to RSS Feeds & Classroom Blogs Start scanning websites you frequent for different variations of this RSS feed icon. Some will have the icon listed in a prominent place on the website, others will just have a text link in the sidebar of footer of the page or some will have NO sign that there is an RSS feed available.

  • Opportunities and Challenges for Standardization in Mobile Social Networks
    Opportunities and Challenges for Standardization in Mobile Social Networks Laurent-Walter Goix, Telecom Italia [email protected] Bryan Sullivan, AT&T [email protected] Abstract This paper describes the opportunities and challenges related to the standardization of interoperable “Mobile Social Networks”. Challenges addressed include the effect of social networks on resource usage, the need for social network federation, and the needs for a standards context. The concept of Mobile Federated Social Networks as defined in the OMA SNEW specification is introduced as an approach to some of these challenges. Further specific needs and opportunities in standards and developer support for mobile social apps are described, including potentially further work in support of regulatory requirements. Finally, we conclude that a common standard is needed for making mobile social networks interoperable, while addressing privacy concerns from users & institutions as well as the differentiations of service providers. 1 INTRODUCTION Online Social Networks (OSN) are dominated by Walled Gardens that have attracted users by offering new paradigms of communication / content exchange that better fit their modern lifestyle. Issues are emerging related to data ownership, privacy and identity management and some institutions such as the European Commission have started to provide measures for controlling this. The impressive access to OSN from ever smarter mobile devices, as well as the growth of mobile- specific SN services (e.g. WhatsApp) have further stimulated the mobile industry that is already starving for new attractive services (RCS 1). In this context OMA 2 as mobile industry forum has recently promoted the SNEW specifications that can leverage network services such as user identity and native interoperability of mobile networks (the approach promoted by “federated social networks”).

  • Privacy Considerations for Secure Identification in Social Wireless
    Privacy considerations for secure identification in social wireless networks Master’s degree thesis ELENA KOZHEMYAK Academic supervisor: Sonja Buchegger, KTH External supervisor: Christian Gehrmann, SICS Examiner: Johan Håstad, KTH September 2011 iii Abstract This thesis focuses on privacy aspects of identification and key exchange schemes for mobile social networks. In particular, we consider identification schemes that combine wide area mobile communication with short range com- munication such as Bluetooth, WiFi. The goal of the thesis is to identify possi- ble security threats to personal information of users and to define a framework of security and privacy requirements in the context of mobile social networking. The main focus of the work is on security in closed groups and the procedures of secure registration, identification and invitation of users in mobile social net- works. The thesis includes an evaluation of the proposed identification and key exchange schemes and a proposal for a series of modifications that augments its privacy-preserving capabilities. The ultimate design provides secure and ef- fective identity management in the context of, and in respect to, the protection of user identity privacy in mobile social networks. Keywords: mobile social networks, identity privacy, identity management, pseudonyms. iv Sammanfattning Det här examensarbetet handlar om personlig integritet, identifiering och nyckelutbyte i mobila sociala nätverk. Speciellt adresserar vi dessa aspekter för system som kombinerar mobil kommunikation med kort räckviddskommunika- tion som Bluetooth och WiFi. Målet med detta arbete är att identifiera möjliga säkerhetshot mot användarinformation och att ta fram ett ramverk för säkerhet och krav på personlig integritet i mobila sociala nätverk. Tyngdpunkten i ar- betet ligger på säkerhet i slutna grupper och förfaranden för säker registrering, identifiering och inbjudan av användare i mobila sociala nätverk.

    La Fée diverse déploie ses ailes Il n’est pas si fréquent que l’équipe Framalang traduise un article depuis la langue italienne, mais la récapitulation bien documentée de Cagizero était une bonne occasion de faire le point sur l’expansion de la Fediverse, un phénomène dont nous nous réjouissons et que nous souhaitons voir gagner plus d’amplitude encore, tant mieux si l’article ci-dessous est très lacunaire dans un an ! Article original : Mastodon, il Fediverso ed il futuro decentrato delle reti sociali Traduction Framalang : alainmi, Ezelty, goofy, MO Mastodon, la Fediverse et l’avenir des réseaux décentralisés par Cagizero Peu de temps après une première vue d’ensemble de Mastodon il est déjà possible d’ajouter quelques observations nouvelles. Tout d’abord, il faut noter que plusieurs personnes familières de l’usage des principaux médias sociaux commerciaux (Facebook, Twitter, Instagram…) sont d’abord désorientées par les concepts de « décentralisation » et de « réseau fédéré ». En effet, l’idée des médias sociaux qui est répandue et bien ancrée dans les esprits est celle d’un lieu unique, indifférencié, monolithique, avec des règles et des mécanismes strictement identiques pour tous. Essentiellement, le fait même de pouvoir concevoir un univers d’instances séparées et indépendantes représente pour beaucoup de gens un changement de paradigme qui n’est pas immédiatement compréhensible. Dans un article précédent où était décrit le média social Mastodon, le concept d’instance fédérée était comparé à un réseau de clubs ou cercles privés associés entre eux. Certains aspects exposés dans l’article précédent demandent peut-être quelques éclaircissements supplémentaires pour celles et ceux qui abordent tout juste le concept de réseau fédéré.
