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.

  • DRC Diaspora Programme, DEMAC and GIZ, As Well As Consultations with Diaspora Communities in Europe for Possible Modalities of Diaspora Engagement
    DRC DIASPORA PROGRAMME, DEMAC & GIZ’ Recommendations on behalf of diasporas to the Global Compact on Refugees’ Programme of Action Key considerations and recommendations to UNHCR and United Nations’ Member States 1 This paper sets forth joint recommendations of Danish Refugee Council Diaspora Programme, DEMAC (Diaspora Emergency Action and Coordination) and Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH (Sector Project Forced Displacement, on behalf of the German Federal Ministry for Economic Cooperation and Development, BMZ) for the Global Compact on Refugees’ Programme of Action, bringing together perspectives from a humanitarian and a development point of view. It is based on the experiences of DRC Diaspora Programme, DEMAC and GIZ, as well as consultations with diaspora communities in Europe for possible modalities of diaspora engagement. The objective of this paper is to ensure that the voices and perspectives of diaspora organisations will be reflected in the Global Compact on Refugee’s Programme of Action. Diasporas are dispersed collectives residing outside their country of origin who “maintain regular or occasional contacts with what they regard as their homeland and with individuals and groups of the same background residing in other host countries” (Sheffer: 2003, 9-10). Diasporas include first generation emigrants and their descendants, former refugees and asylum seekers. “Diaspora and refugee overlap significantly and are neither linear, nor static categories. The terms “refugee” and “diaspora” are situational identities that overlap and shift over time and depending on context. There is no bright line demarcation”. (Research paper No.278: 2016, UNHCR, 4) DRC, DEMAC and GIZ are focusing in this paper on diaspora organisations which are formally constituted entities comprising diaspora members that operate in their countries of settlement and countries of origin, and may also work in neighbouring (third) countries.

  • Hard-Coded Censorship in Open Source Mastodon Clients — How Free Is Open Source?
    Proceedings of the Conference on Technology Ethics 2020 - Tethics 2020 Hard-coded censorship in Open Source Mastodon clients — How Free is Open Source? Long paper Juhani Naskali 0000-0002-7559-2595 Information Systems Science, Turku School of Economics, University of Turku Turku, Finland juhani.naskali@utu.fi Abstract. This article analyses hard-coded domain blocking in open source soft- ware, using the GPL3-licensed Mastodon client Tusky as a case example. First, the question of whether such action is censorship is analysed. Second, the licensing compliance of such action is examined using the applicable open-source software and distribution licenses. Domain blocking is found to be censorship in the literal definition of the word, as well as possibly against some the used Google distribu- tion licenses — though some ambiguity remains, which calls for clarifications in the agreement terms. GPL allows for functionalities that limit the use of the software, as long as end-users are free to edit the source code and use a version of the appli- cation without such limitations. Such software is still open source, but no longer free (as in freedom). A multi-disciplinary ethical examination of domain blocking will be needed to ascertain whether such censorship is ethical, as all censorship is not necessarily wrong. Keywords: open source, FOSS, censorship, domain blocking, licensing terms 1 Introduction New technologies constantly create new challenges. Old laws and policies cannot al- ways predict future possibilities, and sometimes need to be re-examined. Open source software is a licensing method to freely distribute software code, but also an ideology of openness and inclusiveness, especially when it comes to FOSS (Free and Open-source software).

During the event, students repeated their de- mands for changes to the Department of Public Safety (DPS) to Mangelsdorf directly. This move follows last semester’s overnight occu- pation of the DPS parking lot where URAC protes- tors voiced their demands to University President Sarah Manglesdorf and DPS chief Mark Fischer, who promised further discussion. “[President Manglesdorf] had promised us that night [...] that she would be starting to actually have progress with this mental health task force to institute Daniel’s [Law] on campus, and ensure that cops [...] and campus police do not respond to mental health calls on this campus,” URAC orga- nizer and senior Antoinette Nguyen said. “Howev- er, there’s been no update regarding that.” The protest began at the steps of Rush Rhees Li- brary, where many of their actions have started in the past. At around 4:30 p.m., organizers went over the plans to the group of roughly 30 people around the steps.

  • Functional Breakdown of Decentralised Social Networks
    University of Amsterdam Master System and Network Engineering Research Project 2 Functional breakdown of decentralised social networks Student: Supervisor: Wouter Miltenburg Michiel Leenaars [email protected] [email protected] July 6, 2015 Abstract Current centralised social networks are used by a huge number of users for a variety of reasons. With Facebook, Google+, LinkedIn, or Twitter, users are not in control of their own data and access control is centralised and proprietary. Decentralised social networks could be a solution to these problems and gives the control of the data back to users. This research is focused on the question which of the decentralised social networks is currently most suited to be provided as a service by hosting providers. This paper will therefore provide information about the current implementations, the protocols used by the various implementations, and will give a functional breakdown of the various decentralised social networks. Various implementations have been analysed, namely diaspora*, Friendica, GNU social, pump.io, and RedMatrix. The paper also describes the set of standards and protocols used by the various implementations. As most implementations use their own protocol, or implement the standards slightly differently, there is no interoperability without the use of extra plugins or enabling certain features. While there are a lot of standards for facilitating the message exchange, there are however standards missing that would make interoperability possible, which is described in this paper as well. RedMatrix is currently most suited to be provided as an alternative to the current centralised social networks and that can be provided as a service by hosting providers.

Of these 800 million users, 41% are aged between 16 and 24 years. This social network, widely known for its entertainment videos, is increasingly becoming a place for political discussion and therefore a unique opportunity for political actors to (re) connect with young people. Acknowledging that the political uses of TikTok are still understudied, this paper aims to explore whether and how Spanish political parties are includingTikTok as part of their communication strategy. Through an affordance-centered content analysis of all the posts published by the five most important Spanish political parties (PP, PSOE, Ciudadanos, Podemos, and Vox), the current results show that, although all Spanish political parties have adopted this platform, their usage is unequal.
