Opinion-based Homogeneity on YouTube : Combining Sentiment and Social Network Analysis

The growing complexity of political communication online goes along with increasing methodological challenges to process communication data properly in order to investigate public concerns such as the existence of echo chambers. To cover the full range of political diversity in online communication, we argue that it is necessary to focus on specific political issues. This study proposes an innovative combination of computational methods, including natural language processing and social network analysis, that serves as a model for future research on the evolution of opinion climates in online networks. Data were gathered on YouTube, enabling the assessment of users’ expressed opinions on two political issues. Results provided very limited evidence for the existence of opinion-based homogeneity on YouTube. This was true even when the whole network was divided into sub-networks. Findings are discussed in light of current computational communication research and the vigorous debate on echo chambers in online networks

Using ODL and ICT to develop the skills of the unreached: a contribution to the ADEA triennial of the Working Group on Distance Education and Open Learning

Innovation in technology is occurring at rapid pace thus shrinking the distances and making information and knowledge more than ever accessible to everyone irrespective of where the person resides. This paper consists of four main articles. The first one deals with technological trends. The second one focuses on the deployment and use of open and distance education mode in rural areas by documenting initiatives that embrace information and communication technologies (ICTs). Due to challenges faced in rural areas only a few success stories/cases currently exist and some of these are cited in this article. The challenges faced in the deployment of ICT enhanced ODL have been highlighted as well as the potential of developing and delivering effective and relevant ODL programmes in rural areas in order to ensure that issues of educational equity and social exclusion rural communities are adequately addressed. ICTs in ODL are perhaps the greatest tool to date for self-education and value addition to any community’s development efforts, yet poor rural communities particularly in Africa do not have the necessary awareness, skills or facilities to enable themselves to develop using ICTs. Inadequate ICT infrastructures in rural areas remain a major source for the digital divide in Africa and for under-performance of distance learners. The third one analyses the support provided to ODL learners who often encounter difficulties in completing their studies through the distance education mode due to loneliness, uncertainties and de-motivation. ICT has not been able to sufficiently support distance learners in overcoming those obstacles efficiently. An investigation regarding those learning supports has been conducted in ten distance learning institutions, along with an intensive literature review with the aim of understanding the high percentage of dropout rates of distant learners. The learners’ interactions have been scrutinized through content analysis of their synchronous exchanges, during a completely online course. After taking into account the limited technical and human resources in Africa, a technological virtual environment along with a pedagogical framework has been proposed with the aim of giving adequate educational support to them. The fourth article has explored The Open University (UK) and its efforts to use new technologies to deliver online courses to difficult-to- reach learners in prison environments. The case study analysed here is an international course (called, B201- Business Organisations and their environments) which also touches an African cohort of learners. The implications for designing and delivering online ODL to the complex unreachable environments of prisons anywhere, and particularly in Africa, have been discussed

Friends or Foes: Understanding Communication and Interaction Patterns of Homogeneous and Cross-Cutting Spaces in Online Activism

The understanding of people’s communication structure is crucial to answering the ongoing debates about whether social media is a “filter bubble”. Focusing on this topic, our work investigated people’s preference for homogeneous or cross-cutting communications in an online activism setting, also the difference in language use and hyperlink use in different communications types. We used the tweets with #Silent Sam to classify communication types of user interactions. After the metric generation, significance tests, and subgraph mining, we found that people are 15 times more likely to communicate with like-minded people. However, cross-cutting communications increase simultaneously with homogeneous ones when the activity level rises. Also, homogeneous communications significantly use more words related to perception, while cross-cutting ones have more words about cognition. We also unveiled the dark side of the crosscutting communications as they are generally more toxic and aggressive. The use of outside links in the tweets is rare for both cross-cutting and homogeneous communications. Nonetheless, the cross-cutting tweets embed more URLs while they direct to less diverse domains than the homogeneous ones. Left-leaning media sources with mixed to high factuality are linked as the outside source for mostly homogeneous interactions. Our work made contributions in the ways of providing the new methodology of subgraph mining to research about partisan sharing and rendering new insights to the research in online activism.Master of Science in Information Scienc

The Translocation of Culture: Migration, Community, and the Force of Multiculturalism in History

In his work on a Welsh border village, Ronald Frankenberg showed how cultural performances, from football to carnival, conferred agency on local actors and framed local conflicts. The present article extends these themes. It responds to invocations by politicians and policy makers of ‘community cohesion’ and the failure of communal leadership, following riots by young South Asians in northern British towns. Against the critique of self-segregating isolationism, the article traces the historical process of Pakistani migration and settlement in Britain, to argue that the dislocations and relocations of transnational migration generate two paradoxes of culture. The first is that in order to sink roots in a new country, transnational migrants in the modern world begin by setting themselves culturally and socially apart. They form encapsulated ‘communities’. Second, that within such communities culture can be conceived of as conflictual, open, hybridising and fluid, while nevertheless having a sentimental and morally compelling force. This stems from the fact, I propose, that culture is embodied in ritual and social exchange and performance, conferring agency and empowering different social actors: religious and secular, men, women and youth. Hence, against both defenders and critics of multiculturalism as a political and philosophical theory of social justice, the final part of the article argues for the need to theorise multiculturalism in history. In this view, rather than being fixed by liberal or socialist universal philosophical principles, multicultural citizenship must be grasped as changing and dialogical, inventive and responsive, a negotiated political order. The British Muslim diasporic struggle for recognition in the context of local racism and world international crises exemplifies this process. Classification-

Cross-Partisan Discussions on YouTube: Conservatives Talk to Liberals but Liberals Don't Talk to Conservatives

We present the first large-scale measurement study of cross-partisan discussions between liberals and conservatives on YouTube, based on a dataset of 274,241 political videos from 973 channels of US partisan media and 134M comments from 9.3M users over eight months in 2020. Contrary to a simple narrative of echo chambers, we find a surprising amount of cross-talk: most users with at least 10 comments posted at least once on both left-leaning and right-leaning YouTube channels. Cross-talk, however, was not symmetric. Based on the user leaning predicted by a hierarchical attention model, we find that conservatives were much more likely to comment on left-leaning videos than liberals on right-leaning videos. Secondly, YouTube's comment sorting algorithm made cross-partisan comments modestly less visible; for example, comments from conservatives made up 26.3% of all comments on left-leaning videos but just over 20% of the comments were in the top 20 positions. Lastly, using Perspective API's toxicity score as a measure of quality, we find that conservatives were not significantly more toxic than liberals when users directly commented on the content of videos. However, when users replied to comments from other users, we find that cross-partisan replies were more toxic than co-partisan replies on both left-leaning and right-leaning videos, with cross-partisan replies being especially toxic on the replier's home turf.Comment: Accepted into ICWSM 2021, the code and datasets are publicly available at https://github.com/avalanchesiqi/youtube-crosstal

Deliberative democracy and inequality: Two cheers for enclave deliberation among the disempowered

Deliberative democracy grounds its legitimacy largely in the ability of speakers to participate on equal terms. Yet theorists and practitioners have struggled with how to establish deliberative equality in the face of stark differences of power in liberal democracies. Designers of innovative civic forums for deliberation often aim to neutralize inequities among participants through proportional inclusion of disempowered speakers and discourses. In contrast, others argue that democratic equality is best achieved when disempowered groups deliberate in their own enclaves (interest groups, parties, and movements) before entering the broader public sphere. Borrowing from each perspective, the authors argue that there are strong reasons to incorporate enclave deliberation among the disempowered within civic forums. They support this claim by presenting case study evidence showing that participants in such forums can gain some of the same benefits of deliberation found in more heterogeneous groups (e.g., political knowledge, efficacy and trust), can consider a diversity of viewpoints rather than falling into groupthink and polarization, and can persuade external stakeholders of the legitimacy of the group’s deliberations

Adherence to Misinformation on Social Media Through Socio-Cognitive and Group-Based Processes

Previous work suggests that people's preference for different kinds of information depends on more than just accuracy. This could happen because the messages contained within different pieces of information may either be well-liked or repulsive. Whereas factual information must often convey uncomfortable truths, misinformation can have little regard for veracity and leverage psychological processes which increase its attractiveness and proliferation on social media. In this review, we argue that when misinformation proliferates, this happens because the social media environment enables adherence to misinformation by reducing, rather than increasing, the psychological cost of doing so. We cover how attention may often be shifted away from accuracy and towards other goals, how social and individual cognition is affected by misinformation and the cases under which debunking it is most effective, and how the formation of online groups affects information consumption patterns, often leading to more polarization and radicalization. Throughout, we make the case that polarization and misinformation adherence are closely tied. We identify ways in which the psychological cost of adhering to misinformation can be increased when designing anti-misinformation interventions or resilient affordances, and we outline open research questions that the CSCW community can take up in further understanding this cost

Characterizing Disagreement in Online Political Talk: Examining Incivility and Opinion Expression on News Websites and Facebook in Brazil

This paper examines the ways people engage in political conversation triggered by exposure to political news in two different informal platforms in Brazil: Facebook and news websites. We analyze the extent to which disagreement is associated to discursive traits that are commonly associated with deliberative behavior, such as directly engaging with others, and trying to justify one’s views, and negative traits, such as incivility. The contributions of this paper can be summarized as follows. First, this paper emphasizes the importance of looking beyond a single platform and a single topic to understand political discussion online. Second, we demonstrate that online disagreement is positively associated with both deliberative traits, such as justified opinion expression, and non-deliberative traits, such as incivility, and argue that the latter is not enough to dismiss the value of political talk. We also demonstrate that the topic of a news story is relevant both to drive political conversation and to spark political disagreement: controversies involving celebrities and stories covering international affairs are more likely to drive heterogeneous conversations than more conventional political topics (e.g. government, policy), even though these are the topics that tend to attract more political talk. Finally, this study contributes to fill an important gap in the literature, looking beyond the US and Western European contexts by examining political talk in Brazil, the fourth largest digital market in the world
