Abstract: Charitable crowdfunding is an important source of funds for charitable organizations. The offer of tokens or rewards is often used to entice potential donors to donate to a cause. This study investigates when it is beneficial to offer rewards in a charitable crowdfunding campaign. Three design principles are developed from the current literature which aim to help in the creation of a successful crowdfunding campaign. Important factors identified were types of donations a charitable organization usually receives, the groups of donors associated with that organization and the need for one time considerably large donations.

Sharing Knowledge about Open Source Licenses at DLR

Title: Sharing Knowledge about Open Source Licenses at DLR

Authors: Andreas Schreiber:German Aerospace Center; Carina Haupt:German Aerospace Center

Abstract: In science, more and more software is published as Open Source software or uses Open Source projects. Therefore, scientists must be aware of requirements, restrictions and compatibility issues of Open Source licenses. We describe our strategy at the German Aerospace Center (DLR) to awake the awareness among our domain scientists and to enable and support them in publishing Open Source software, which is free of license issues. We provide hands-on material, offer training courses, and foster knowledge sharing between peer scientists. Findings and feedback prove the usefulness and effectiveness.

Stick or Twist: Balancing Blockchain Decentralisation and Miner Pooling

Title: Stick or Twist: Balancing Blockchain Decentralisation and Miner Pooling

Authors: David Sheehan:University College Cork; Rob Gleasure:University College Cork;
Joe Feller:University College Cork; Shanping Li:Zheijiang University; Jerry Cristiforo:State Street

Abstract: The Emerging Blockchain technologies have earned substantial attention in the area of Financial Technology in recent years. Its decentralized environment allows for the mining of Bitcoins by miners either independently or in groups. The community of miners have faith in the integrity of each other to sustain the network, through mining pools remaining at a reasonable level of mining power. Blockchain’s decentralized system is one of its main selling points and is a source of great attraction for users. However, when these mining pools start to grow and increase their mining power to dangerous levels it can result in a shift towards a centralized environment. This push goes against foundational principles of Bitcoin, leading to ongoing debate among various stakeholders.

Abstract: Crowdfunding is a rapidly growing phenomenon and is becoming a viable alternative to traditional financial institutions for small business fund seekers. Crowdfunding involves harnessing small individual investments from a large number of investors. This paper explores four key risks associated with crowdfunding: Money Laundering, IP Theft, Fraud, and “Failure by Success.” The paper then outlines key research questions for the next stage of the research, which will empirically investigate how crowdfunding platforms self-govern against these risks.

Open Peer Review CMS Support

Title: Open Peer Review CMS Support

Authors: Oliver Zendel:Austrian Institute of Technology; Matthias Schorghuber:Austrian Institute of Technology; Michela Vignoli:Austrian Institute of Technology

Abstract: Peer reviewing is a crucial step for quality assurance at scientific publishing. The task is time consuming and error-prone due to conflicts of interest, subjective opinions, and different education backgrounds. Open Peer Review (OPR) can solve many of said problems and is already applied to the journal publishing workflow. The poster visualizes the efforts done in the EU project OpenUP to evaluate the usefulness of OPR for conference submissions. Two conference venues will try out specific versions of OPR. The conference management software (CMS) needed to facilitate this process is summarized. The CMS solution HotCRP was chosen among the evaluated options for the pilots. The poster introduces the individual processes of open peer review at the two venues and how this is supported in HotCRP. This shall give conference organizers an insight into what is possible and allow for discussions with the OpenUP team about the selected approaches.

How is Value Created within an Inner Source Environment?

Title: How is Value Created within an Inner Source Environment?

Author: Noel Carroll:University of Limerick

Abstract: Awareness and indeed adoption of open source practices inside corporate entities, something termed Inner Source, has become quite popular in recent years. However, the majority of research efforts focus on industry-driven Inner Source adoption with little or no conceptual accounts of how value is created and sustained within Inner Source environments. This research-in-progress explains how an Inner Source Capability Maturity Model (IS-CMM) can offer a structure to guide Inner Source strategies and sustaining value co-creation.

An Author Network to Classify Open Online Discussions

Title: An Author Network to Classify Open Online Discussions

Authors: Mattias Mano:i3-Centre de Recherches en Gestion, Ecole Polytechnique;
Jean-Michel Dalle:University Pierre et Marie Curie;
Joanna Tomasik:Centrale Supelec

Abstract: Among other modalities, online coordination can notably rely on discussions and forums. However, and notwithstanding increasing research efforts, direct approaches that would help communities and moderators distinguish between gossip and serious debates are still largely missing. We present an innovative methodology to detect the different structures of online discussions in the sub-Reddit Change My View. Applying a clustering algorithm to the author networks, we highlight three distinct classes characterized by alternative behaviors. To better understand the underlying social dynamics, we implement a relational event model that provides evidence for three effects whose influence can affect the structure of online discussions.

Current and alternate approaches to personalization in online learning

Title: Current and alternate approaches to personalization in online learning

Authors: Debora Jeske:University College Cork; Mammed Bagher:Edinburgh Napier University; Nadia Pantidi:University College Cork

Abstract: In the context of distance (online) learning programs, the current paper focuses on two specific goals. First, we outline how personalization based on learning analytics has been implemented in online programs offered by traditional universities, but also providers of MOOCs and virtual institutions. However, this established approach is not without its limitations. Second, we introduce two alternate concepts that may support personalization based on work around readability indices and job crafting. These approaches may also help to address some of the limitations of learning analytics. The emphasis is on how personalization may support the development of individual learning paths that would provide means for both self-pacing and co-construction of the experience. The paper concludes with a review of facilitating and challenging factors for program leaders, online technical staff and designers working in open educational contexts.

Supporting Awareness of Content-related Controversies in a Wiki-based Learning Environment

Title: Supporting Awareness of Content-related Controversies in a Wiki-based Learning Environment

Authors: Sven Heimbuch (University of Duisburg-Essen), Daniel Bodemer (University of Duisburg-Essen)

Abstract: User generated content in Wikis is mainly distributed on the article view and its corresponding talk page. Potentials of analysing and supporting discussants’ knowledge construction processes on the level of talk pages have still been rarely researched. The presented experimental study addresses this issue by providing external representations of content-related controversies which were led by contradictory evidence between discussants to foster awareness on socio-cognitive conflicts which can be beneficial for learning. Its aim is to investigate how increased salience of controversies can guide participants’ (N = 81) navigation and learning processes. Three conditions differing in their degree of awareness support were implemented in this study. Results indicate that the implementation of awareness representations helped students to focus on meaningful discussion threads. Findings suggest that Wiki talk page users can benefit from additional structuring aids.

Geographic and Linguistic Normalization: Towards a Better Understanding of the Geo-linguistic Dynamics of Knowledge

Title: Geographic and Linguistic Normalization: Towards a Better Understanding of the Geo-linguistic Dynamics of Knowledge

Authors: Han-Teng Liao, Thomas Petzold

Abstract: This paper proposes a method of geo-linguistic normalization to advance the existing comparative analysis of open collaborative communities, with multilingual Wikipedia projects as the example. Such normalization requires data regarding the potential users and/or resources of a geolinguistic unit.
