From Birdwatch to Community Notes, from Twitter to X: four years of community-based content moderation

Community Notes (formerly known as Birdwatch) is the first large-scale crowdsourced content moderation initiative launched by X (formerly Twitter) in January 2021. As the Community Notes model gains momentum across other social media platforms, there is a growing need to assess its underlying dynamics and effectiveness. This paper provides a descriptive investigation of Community Notes during its first four years, examining its linguistic diversity, sourcing practices, Contributor activity, rating behaviour, and interaction networks. In addition, we release a curated dataset and accompanying source code to support future research, along with a review of prior research on Community Notes. We parsed Notes and ratings data from the first four years of the program and conducted language detection across all Notes. For English-language Notes, we extracted embedded URLs and identified discussion topics in each Note. Additionally, we constructed monthly interaction networks among the Contributors. Together, the descriptive analysis, dataset, code, and literature review provide a foundation for advancing research on Community Notes and community-based content moderation more broadly.

Toward a Full-Stack Framework for Industrial Augmented Reality: Benefits, Risks, and Design Considerations for Dependable Deployment in Manufacturing

Industrial Augmented Reality (AR) has progressed from laboratory demonstrations to operational pilots across design, training, assembly, maintenance and quality assurance, yet broad, dependable deployment in manufacturing remains the exception. We synthesise existing evidence into a full-stack deployment framework structured along six distinct but coupled decision axes: (i) value and benefits, (ii) technical and integration constraints, (iii) human factors and safety, (iv) organisational and economic considerations, (v) data, security and privacy, and (vi) governance, ethics and long-term risk. Within each axis we separate (a)benefits, (b)failure modes and (c)design considerations, and cross-link them through a deployment checklist that engineering managers and vendors can apply when scoping projects. The contribution is conceptual and practice-oriented: a synthesis grounded in the literature and public deployment reports. We mark where the evidence base is mature (e.g. assembly task time, training efficacy), emerging (e.g. cognitive workload trade-offs, cobot safety zones), or speculative (e.g. metaverse-scale governance), and identify open questions whose resolution conditions the transition from demos to dependable infrastructure.

Willingness to Pay for an Electricity Connection: A Choice Experiment Among Rural Households and Enterprises in Nigeria

Rural electrification initiatives worldwide frequently encounter financial planning challenges due to a lack of reliable market insights. This research delves into the preferences and marginal willingness to pay (mWTP) for upfront electricity connections in rural and peri-urban areas of Nigeria. We investigate discrete choice experiment data gathered from 3,599 households and 1,122 Small to Medium-sized Enterprises (SMEs) across three geopolitical zones of Nigeria, collected during the 2021 PeopleSuN project survey phase. Employing conditional logit modeling, we analyze this data to explore preferences and marginal willingness to pay for electricity connection. Our findings show that households prioritize nighttime electricity access, while SMEs place a higher value on daytime electricity. When comparing improvements in electricity capacity to medium or high-capacity, SMEs exhibit a sharp increase in willingness to pay for high-capacity, while households value the two options more evenly. Preferences for the electricity source vary among SMEs, but households display a reluctance towards diesel generators and a preference for the grid or solar solutions. Moreover, households with older heads express greater aversion to connection fees, and male-headed households show a stronger preference for nighttime electricity compared to their female-headed counterparts. The outcomes of this study yield pivotal insights to tailor electrification strategies for rural Nigeria, emphasizing the importance of considering the diverse preferences of households and SMEs.

Electricity supply and use among rural and peri-urban households and small firms in Nigeria

Improving access to energy services among the underserved requires understanding the status quo in energy access and estimating future energy requirements of energy service provision. In this paper, we present a novel survey dataset collected in 2021 within the framework of the PeopleSuN project. Across three Nigerian geopolitical zones, a total of 3,599 households and 1,122 small and medium-sized enterprises were surveyed. The sample is representative of grid-electrified regions of each zone, excluding urban centres. Our surveys collect data on demographic and socioeconomic characteristics, energy access and supply quality, electrical appliance ownership and usage time, cooking solutions, capabilities, and preferences. We encourage academic use of the data presented and suggest three avenues of further research: (1) modelling appliance ownership likelihoods, electricity consumption levels and energy service needs in un-electrified regions; (2) modelling the integration of decentralised renewable and battery storage solutions to address high usage of diesel generators in peri-urban regions; (3) exploring broader issues of multi-dimensional energy access, access to decent living standards and climate vulnerability.

Optimization of the post-crisis recovery plans in scale-free networks

General Motors or a local business, which one is better to be stimulated in post-crisis recessions, where government stimulation is meant to overcome recessions? Due to the budget constraints, it is quite relevant to ask how one can increase the chance of economic recovery. One of the key elements to answer this question is to understand metastable features of the economic networks. Ising model has been suggested for studying such features in the literature. In the homogenous networks one needs at least a minimum activation, forcing an Ising network to switch its local equilibria, where such minimum is independent of the nodes characteristics. In the scale free networks however, when one aims to push the network to switch its vacuum, she faces the question of which nodes are better to be stimulated to minimize the cost. In the paper it has been shown that stimulation of the high degree nodes costs less in general. Despite regular networks, in the scale free networks, the stimulation cost depends on the networks features such as assortativity. Though we have utilized the Ising model to tackle a problem in economics, our analysis shed lights on many other problems concerning stimulations of socio-economic systems.
