Drivers of social influence in the Twitter migration to Mastodon.

The migration of Twitter users to Mastodon following Elon Musk's acquisition presents a unique opportunity to study collective behavior and gain insights into the drivers of coordinated behavior in online media. We analyzed the social network and the public conversations of about 75,000 migrated users and observed that the temporal trace of their migrations is compatible with a phenomenon of social influence, as described by a compartmental epidemic model of information diffusion. Drawing from prior research on behavioral change, we delved into the factors that account for variations of the effectiveness of the influence process across different Twitter communities.

Circular Business Model for Digital Health Solutions: Protocol for a Scoping Review.

Background: The circular economy reshapes the linear "take, make, and dispose" approach and evolves around minimizing waste and recapturing resources in a closed-loop system. The health sector accounts for 4.6% of global greenhouse gas emissions and has, over the decades, been built to rely on single-use devices and deal with high volumes of medical waste.

Narrating Digital Access, Trauma, and Disability Through Comics and Image Description in Denmark.

Anthropologists explore sequential art, particularly comics, as an accessible medium to co-produce knowledge about trauma and disability with research collaborators. However, practices of image description developed by blind scholars and artists need to be integrated into these projects to ensure visual studies are accessible. Collaborating with sighted service users of drop-in centers in Denmark, we reflect on the process of creating comics and image descriptions about their experiences with digital access, trauma, and disability.

What are the odds? Poor compliance with UK loot box probability disclosure industry self-regulation.

Loot boxes are purchased in video games to obtain randomised rewards of varying value and are thus psychologically akin to gambling. Disclosing the probabilities of obtaining loot box rewards may reduce overspending, in a similar vein to related disclosure approaches in gambling. Presently, this consumer protection measure has been adopted as law only in the People's Republic of China (PRC).

Loot boxes, gambling-related risk factors, and mental health in Mainland China: A large-scale survey.

Loot boxes can be bought with real-world money to obtain random content inside video games. Loot boxes are viewed by many as gambling-like and are prevalently implemented globally. Previous Western and international studies have consistently found loot box spending to be positively correlated with problem gambling.

Mobile robotics in smart farming: current trends and applications.

In recent years, precision agriculture and smart farming have been deployed by leaps and bounds as arable land has become increasingly scarce. According to the Food and Agriculture Organization (FAO), by the year 2050, farming in the world should grow by about one-third above current levels. Therefore, farmers have intensively used fertilizers to promote crop growth and yields, which has adversely affected the nutritional improvement of foodstuffs.

The Trouble of Stigma in the Age of Datafication: Screening for Mental Health Issues in a Refugee Camp in Jordan.

Drawing on ethnographic fieldwork in a refugee camp in Jordan, this article investigates how datafication through digital screening technologies helps shape mental health issues in the face of widespread uneasiness about the subject, especially among the intended beneficiaries. We argue that the refugees and their health care providers face a dilemma: on the one hand, the desire to make mental health issues visible and clinically actionable through datafication and, on the other hand, the wish to keep mental health issues out of public view to avoid potential stigma.

No evidence that Chinese playtime mandates reduced heavy gaming in one segment of the video games industry.

Governments around the world are considering regulatory measures to reduce young people's time spent on digital devices, particularly video games. This raises the question of whether proposed regulatory measures would be effective. Since the early 2000s, the Chinese government has been enacting regulations to directly restrict young people's playtime.

Characteristics of Users and Nonusers of Symptom Checkers in Germany: Cross-Sectional Survey Study.

Background: Previous studies have revealed that users of symptom checkers (SCs, apps that support self-diagnosis and self-triage) are predominantly female, are younger than average, and have higher levels of formal education. Little data are available for Germany, and no study has so far compared usage patterns with people's awareness of SCs and the perception of usefulness.

Objective: We explored the sociodemographic and individual characteristics that are associated with the awareness, usage, and perceived usefulness of SCs in the German population.

CastNet: a systems-level sequence evolution simulator.

Background: Simulating DNA evolution has been done through coevolution-agnostic probabilistic frameworks for the past 3 decades. The most common implementation is by using the converse of the probabilistic approach used to infer phylogenies which, in the simplest form, simulates a single sequence at a time. However, biological systems are multi-genic, and gene products can affect each other's evolutionary paths through coevolution.

Green politics beyond the state: radicalizing the democratic potentials of climate citizens' assemblies.

In recent years, countries like France, UK, Germany, and Denmark have all carried out climate citizens' assemblies where a group of representatively selected citizens come together to discuss issues around climate politics and provide policy recommendations to decision-makers. The hope is that these deliberative-democratic innovations can circumvent the flaws of representational politics and help break the existing gridlock around climate politics. In this article, relying on the case of the Danish climate citizens' assembly that began its work in 2020, we argue that to truly realize the democratic potentials of climate citizens' assemblies, there is a need to think about how citizens' assemblies might come to multiply and proliferate in political spaces away from, or at least in addition to, those in and around the state, so they can become local drivers of democratic action and community empowerment.

To analyze or to throw away? On the stability of excitation-emission matrices for different water systems.

Fluorescence spectroscopy has numerous applications to characterize natural and human-influenced water bodies regarding dissolved organic matter (DOM) and contamination. Analyzing samples in a timely manner is crucial to gaining valid and reproducible excitation-emission matrices (EEM) but often difficult, specifically in transnational projects with long transport distances. In this study, eight samples of different water sources (tap water, differently polluted rivers, and wastewater treatment plant (WWTP) effluents) were stored under standardized conditions for 59 days and analyzed regularly.

Beneath the label: unsatisfactory compliance with ESRB, PEGI and IARC industry self-regulation requiring loot box presence warning labels by video game companies.

Loot boxes in video games are a form of in-game transactions with randomized elements. Concerns have been raised about loot boxes' similarities with gambling and their potential harms (e.g.

Debate: Academics should collaborate with the technology industry, but not in lieu of noncollaborative research.

Academic research collaborations with the technology industry should be complementary to and, importantly, must not replace noncollaborative research that is independent from the industry (and, in particular, 'adversarial research' whose negative findings will likely operate against industry interests). Reflecting on the author's own research projects concerning companies' compliance with video game loot box regulation, he agrees with Livingstone et al.'s proposition (Child and Adolescent Mental Health, 2022, 28, 150) that research seeking to identify problems (and thereby work against the industry's interests) should be conducted independently (p.

Quantifying ideological polarization on a network using generalized Euclidean distance.

An intensely debated topic is whether political polarization on social media is on the rise. We can investigate this question only if we can quantify polarization, by taking into account how extreme the opinions of the people are, how much they organize into echo chambers, and how these echo chambers organize in the network. Current polarization estimates are insensitive to at least one of these factors: They cannot conclusively clarify the opening question.

Selection of and Response to Physical Activity-Based Social Comparisons in a Digital Environment: Series of Daily Assessment Studies.

Background: Innovative approaches are needed to understand barriers to and facilitators of physical activity among insufficiently active adults. Although social comparison processes (ie, self-evaluations relative to others) are often used to motivate physical activity in digital environments, user preferences and responses to comparison information are poorly understood.

Objective: We used an iterative approach to better understand users' selection of comparison targets, how they interacted with their selected targets, and how they responded to these targets.

Patients' and healthcare professionals' perceived facilitators and barriers for shared decision-making for frail and elderly patients in perioperative care: a scoping review.

Background: Shared decision-making (SDM) in perioperative care, is an organizational approach to instituting sharing of information and decision-making around surgery. It aims at enabling patient autonomy and patient-centered care. Frail and elderly patients suffering from multiple health conditions and increased surgical vulnerability might particularly benefit from SDM.

[The maturity model for the public health service-a tool for assessing and improving the digital maturity level of German public health agencies].

The COVID 19 crisis has highlighted the key role of the public health service (PHS), with its approximately 375 municipal health offices involved in the pandemic response. Here, in addition to a lack of human resources, the insufficient digital maturity of many public health departments posed a hurdle to effective and scalable infection reporting and contact tracing. In this article, we present the maturity model (MM) for the digitization of health offices, the development of which took place between January 2021 and February 2022 and was funded by the German Federal Ministry of Health.

Memory-aware curriculum federated learning for breast cancer classification.

Background And Objective: For early breast cancer detection, regular screening with mammography imaging is recommended. Routine examinations result in datasets with a predominant amount of negative samples. The limited representativeness of positive cases can be problematic for learning Computer-Aided Diagnosis (CAD) systems.

Representative Participation in a Large-Scale Health IT Project.

User involvement is widely recognized as best practice in the development of information technology (IT) systems. In large-scale IT projects, the involvement of users and other stakeholder groups is typically in the form of representatives, as opposed to the direct (in-person) participation characteristic for smaller projects. The potential new sharing of power that representative participation entails vis-à-vis direct stakeholder involvement, and the implications of such a shift, are an important discussion in the context of participatory design.

Multidimensional tie strength and economic development.

The strength of social relations has been shown to affect an individual's access to opportunities. To date, however, the correspondence between tie strength and population's economic prospects has not been quantified, largely because of the inability to operationalise strength based on Granovetter's classic theory. Our work departed from the premise that tie strength is a unidimensional construct (typically operationalized with frequency or volume of contact), and used instead a validated model of ten fundamental dimensions of social relationships grounded in the literature of social psychology.
