Social media have been fundamental in the daily lives of millions of people, but they have raised concerns about content moderation policies, the management of personal data, and their commercial exploitation. The acquisition of Twitter (now X) by Elon Musk in 2022 generated concerns among Twitter users regarding changes in the platform’s direction, prompting a migration campaign by some user groups to the federated network Mastodon. This study reviews the onboarding of users to this decentralised platform between 2016 and 2022 and analyses the migration of 19,000 users who identified themselves as supporters of the platform switch. The results show that the migration campaign was a reactive response to Elon Musk’s acquisition of Twitter and was led by a group of highly active academics, scientists, and journalists. However, a complete transition was not realised, as users preferred to straddle their presence on both platforms. Mastodon’s decentralisation made it difficult to exactly replicate Twitter’s communities, resulting in a partial loss of these users’ social capital and greater fragmentation of these user communities, which highlights the intrinsic differences between both platforms.

Employing a critical approach typical of humanities-based research, this article investigates the changing nature of toxic leadership in our digital world. Drawing on the perspective of media ecology, which asserts that the prevailing communication technologies at a given moment create the social conditions that, in turn, condition us, the authors illustrate how the digital logics of publicity, intransigence, impertinence, and impulsivity remake the contours of leadership. Based on a critical case study of Elon Musk’s public management of Twitter, which has subsequently been rebranded as “X”, it is argued that the four digital logics transform toxic leadership into digital authoritarianism, an unabashed form of authoritarian rule. A concluding section of the essay explores the implications of this evolution for traditional categories of leadership; the importance of attending to communication technologies in leadership research; and the individual, institutional, and social harms of digital authoritarianism.

Twitter, one of the most important social media platforms, has been in the headlines regularly since its acquisition by Elon Musk in October 2022. This acquisition has had a strong impact on the employees, functionality, and discourse on Twitter. So far, however, there has been no analysis that examines the perception of the acquisition by the users on the platform itself. For this purpose, in this paper, we use georeferenced Tweets from the US and classify them using a polarity-based sentiment analysis. We find that the number of Tweets about Twitter and Elon Musk has increased significantly, as have negative sentiments on the subject. Using a spatial hot spot analysis, we find distinct centres of discourse, but no clear evidence of their significant change over time. On the West Coast, however, we suspect the first signs of polarisation, which could be an important indication for the future development of discourse on Twitter. Full article

The usage of large private and business jets, from those owned by Elon Musk to Kylie Jenner and Bernard Arnault, has recently attracted considerable attention in many countries. Enabled by open and crowdsourced aircraft tracking systems based on the automatic dependent surveillance–broadcast protocol, the aircraft and their owners have been scrutinized. While the underlying technology is not novel and its privacy issues have been discussed for years, the increased attention has led to the backlash against open tracking data and, consequently, a scramble to find possible solutions to hide private jets from the public eye. In this paper, we analyze two such methods, which have not yet been discussed previously in the literature: blocking requests to web tracking platforms and malicious editing of crowdsourced databases. We draw on data from the OpenSky Network and illustrate the futility of such approaches. Finally, we outline the type of stakeholders and aircraft deploying such methods, as well as demonstrate the level of environmental impact that might have otherwise been missed by the public.

Corporate social responsibility (CSR) has become increasingly important for companies in recent years. On the one hand, regulatory frameworks require the disclosure of measures for sustainable management. On the other hand, for long-term corporate success, stakeholders must be strategically engaged in the dialog on sustainability aspects. Social media and Twitter in particular offer the potential to foster a meaningful stakeholder dialogue on CSR topics. Twitter’s strategic realignment due to Elon Musk’s acquisition in the fall of 2022, provides an opportunity to capture research results on activities and strategies on the platform systematically, and to synthesize information for future comparative longitudinal studies of changes in usage. We conducted a literature review including 42 papers to contribute to the body of evidence on CSR communication strategies on Twitter across industries and countries, by deriving interdisciplinary suggestions for strategic CSR-related stakeholder management. Results cover relevant CSR topics, prioritized stakeholder groups for CSR communication on Twitter, and successful communication strategies for companies to obtain beneficial results, such as generating social media capital. The results contribute to the strategic planning and implementation of CSR stakeholder management on Twitter, and offer starting points for future studies on social-media mining and CSR communication strategies.

Tweets seem to impact diverse assets, especially during stressful periods. However, their interrelations during stressful events may change. Cryptos are apparently more sensitive to the sentiment spread by tweets. Therefore, a construct could be formed to study such complex interrelation during stressful events. This study found an interesting outcome while investigating three major asset classes (namely, Equity, Gold and Bond) alongside negative sentiment (derived from tweets of Elon Musk) and Dogecoin (an emerging asset class) from 1 June 2015 to 20 February 2022. Negative sentiment emerged as the significant risk transmitter, while Gold emerged as the significant net recipient of shocks (risk). Interestingly, Dogecoin was found to be less impacted and not impactful (not transmitting shock and receiving tiny shocks) at the same time. In fact, the interconnectedness between negative sentiment (percolated through Twitter) and Dogecoin prices was found to be rather feeble. Further, the study showed that the COVID-19 breakout and Brexit referendum in 2016 were less stressful events compared to the Greek debt crisis back in 2015. Full article

Green hydrogen has been known in the UK since Robert Boyle described flammable air in 1671. This paper describes how green hydrogen has become a new priority for the UK in 2021, beginning to replace fossil hydrogen production exceeding 1 Mte in 2021 when the British Government started to inject significant funding into green hydrogen sources, though much less than the USA, Germany, Japan and China. Recent progress in the UK was initiated in 2008 when the first UK green hydrogen station opened in Birmingham University, refuelling 5 hydrogen fuel cell battery electric vehicles (HFCBEVs) for the 50 PhD chemical engineering students that arrived in 2009. Only 10 kg/day were required, in contrast to the first large, green ITM power station delivering almost 600 kg/day of green hydrogen that opened in the UK, in Tyseley, in July 2021. The first question asked in this paper is: ‘What do you mean, Green?’. Then, the Clean Air Zone (CAZ) in Birmingham is described, with the key innovations defined. Progress in UK green hydrogen and fuel cell introduction is then recounted. The remarks of Elon Musk about this ‘Fool Cell; Mind bogglingly stupid’ technology are analysed to show that he is incorrect. The immediate deployment of green hydrogen stations around the UK has been planned. Another century may be needed to make green hydrogen dominant across the country, yet we will be on the correct path, once a profitable supply chain is established in 2022. Full article

The future is not what it used to be. A new strain of futurism has taken over the stage of global science-fiction: one whose understanding of the future cannot be distinguished from its understanding of the present. Gone are the days when extraterrestrials in shiny, extravagant outfits mastered fascinating technologies that flirted with magic. Characters in Charlie Brooker’s Black Mirror (2015–2020) dress like us, and the dystopian technology they put up with is, for the most part, a technology that has existed for years. Armando Iannucci’s imagining of a space cruise for rich people in Avenue 5 (2020) overlaps with Elon Musk’s actual plans of sending wealthy tourists to the moon, while Albert Robida’s visionary téléphonoscope (1879) amounts to a sad reminder of our everyday Zoom call. Is not the current COVID-19 crisis the blueprint to the ultimate post-apocalyptic script? Spanish filmmaker Juan Antonio Bayona noted in a recent interview that Steve Soderbergh’s Contagion (2011), originally labeled as a sci-fi movie by IMDB, is now a drama according to the same internet portal. Science is not fiction anymore, which means at least two different things: that science has lost the power to convey the kind of awe that may be later turned into fiction, and that fiction seems to be unable to inspire a narrative of scientific or—broadly speaking—human progress. How can we retrieve the emancipatory value of progress in good old futuristic sci-fi when the future coincides with the present? What should cultural production look like to help us imagine an alternative to financial capitalism in the face of the impossibility of utopia? The answer, I will claim, resides in Franco Berardi’s concept of “futurability”. This paper explores the limits of this concept by reading side by side Javier Olivares’ and Pablo Olivares’ The Ministry of Time (2015) and Oriol Paulo’s Mirage (2018). Full article

High-speed capsular vehicles are firstly suggested as an idea by Elon Musk of Tesla Company. Unlike conventional high-speed trains, capsular vehicles are individual vessels carrying passengers and freight with the expected maximum speed of near 1200 [km/h] in a near-vacuum tunnel. More individual vehicle speed, dispatch, and position control in the operational aspect are expected over connected trains. This numerical study and investigation evaluate and analyze inter-distance control and their characteristics for high-speed capsular vehicles and their operational aspects. Among many aspects of operation, the inter-distance of multiple vehicles is critical toward passenger/freight flow rate and infrastructural investment. In this paper, the system’s equation, equation of the motion, and various characteristics of the system are introduced, and in particular control design parameters for inter-distance control and actuation are numerically shown. As a conclusion, (1) Inter-distance between vehicles is a function of error rate and second car start time, the magnitude range is determined by second car start time, (2) Inter-distance fluctuation rate is a function of error rate and second car start time, however; it can be minimized by choosing the correct second car start time, and (3) If the second car start time is chosen an integer number of push-down cycle time at specific velocity error rate, the inter-distance fluctuation can be zero.

Obesity is a key correlate of severe SARS-CoV-2 outcomes while the role of obesity on risk of SARS-CoV-2 infection, symptom phenotype, and immune response remain poorly defined. We examined data from a prospective SARS-CoV-2 cohort study to address these questions. Serostatus, body mass index, demographics, comorbidities, and prior COVID-19 compatible symptoms were assessed at baseline and serostatus and symptoms monthly thereafter. SARS-CoV-2 immunoassays included an IgG ELISA targeting the spike RBD, multiarray Luminex targeting 20 viral antigens, pseudovirus neutralization, and T cell ELISPOT assays. Our results from a large prospective SARS-CoV-2 cohort study indicate symptom phenotype is strongly influenced by obesity among younger but not older age groups; we did not identify evidence to suggest obese individuals are at higher risk of SARS-CoV-2 infection; and remarkably homogenous immune activity across BMI categories suggests immune protection across these groups may be similar.

Recent research in cryptocurrencies has considered the effects of the behavior of individuals on the price of cryptocurrencies through actions such as social media usage. However, some celebrities have gone as far as affixing their celebrity to a specific cryptocurrency, becoming a crypto-tastemaker. One such example occurred in April 2021 when Elon Musk claimed via Twitter that “SpaceX is going to put a literal Dogecoin on the literal moon”. He later called himself the “Dogefather” as he announced that he would be hosting Saturday Night Live (SNL) on 8 May 2021. By performing sentiment analysis on relevant tweets during the time he was hosting SNL, evidence is found that negative perceptions of Musk’s performance led to a decline in the price of Dogecoin, which dropped 23.4% during the time Musk was on air. This shows that cryptocurrencies are affected in real time by the behaviors of crypto-tastemakers. Full article

This paper presents an analysis and interpretation of the current state of play in the global value network of minerals mining, refining and transformation processes in the contemporary battery industry, which will power potentially crucial future industries for manufacture of electric vehicles (EVs) and solar-storage energy systems. The dark influence of the carbon lock-in landscape is gradually being mitigated under the challenge of achieving the “500 mile” battery charge, which would make a transformational difference in the replacement of renewably fuelled vehicles and storage systems, currently still predominantly driven by fossil fuels. The challenge has led to a “war” between manufacturers, miners and refiners, who have realised that the challenge has come alive while most have been vacillating. At an “individualist” rather than an “institutionalist” level, Elon Musk, for all his faults, deserves credit for “moving the market” in these two important industry sectors. This paper anatomises key events and processes stimulating change in this global economic activity through an “abductive” reasoning model and a qualitative “pattern recognition” methodology that proves valuable in achieving rational, probabilistic forecasts. Established incremental innovation characterises first responses in the “war” but research agencies like ARPA are active in funding research that may produce radical battery innovation in future.

This paper compares and contrasts three disruptive models of potential and actual new kinds of spatial planning. These include “seasteading”, “smart neighbourhoods” and “renewable spatial systems”. Each is labelled with distinctive discursive titles, respectively: “Attention Capitalism”; “Surveillance Capitalism” and “Sustainable Capitalism” denoting the different lineaments of each, although they all have their origins in the Silicon Valley techno-entrepreneurial milieu. In each case, while the path dependences of trajectories have diverged the progenitors were often erstwhile business partners at the outset. The paper is interested in qualitative methodology and proposes “pattern recognition” as a means to disclose the deep psychological, sociological, political and economic levels that inform the surface appearances and functions of the diverse spatial planning modes and designs that have been advanced or inferred from empirically observable initiator practice. “Dark Triad” analysis is entailed in actualising psychological deep structures. Each of the three models is discussed and the lineaments of their initiators’ ideas are disclosed. Each “school” has a designated mentor(s), respectively: academic B. J. Fogg and venture capitalist Peter Thiel for “Attention Capitalism”, “smart city” planner Dan Doctoroff for “Surveillance Capitalism” and “renewable energineer” and Elon Musk for “Sustainable Capitalism”, the eventual winner of this existential “dark versus light triad” urban planning contest.

What CEO attributes can improve corporate sustainability? In this regard, what do superstar CEOs, e.g., Mark Zuckerberg, Jeff Bezos, Elon Musk, and Bill Gates, have in common? Also, did the personalities of Jeffrey Skilling and Kenneth Lay contribute to the crack in the US Enron Corporation early in this century? Why, as far as presidential elections are concerned, are some countries, more than others, more likely to vote for seemingly narcissistic politicians? In our practice-oriented review article, we aim to contribute to shedding new light on the challenging evidence continuously evolving around CEOs, in general, and around their effect on corporate sustainability, in particular. Two distinctive features represent the main “so-what” value of our work. First, each of the CEO attributes which we sequentially focus on (i.e., power, personality, profiles, and effect) is, at the beginning, not only separately considered but also associated with many recent examples from business life and from the “CEO world” at an international level. Second, from our analysis, we then derive a conceptual framework which, combining all these attributes into a unique body of knowledge, could be used as a potential starting point for future investigations in this challenging research area regarding the CEO/sustainability relationship. In this regard, we believe understanding how all the analysed attributes coevolve will represent a pivotal question to address if we want to enhance the scientific and practical understanding of CEO (sustainable) behaviour.

Residential photovoltaic (PV) battery systems increase households’ electricity self-consumption using rooftop PV systems and thus reduce the electricity bill. High investment costs of battery systems, however, prevent positive financial returns for most present residential battery installations in Germany. Tesla Motors, Inc. (Palo Alto, CA, USA) announced a novel battery system—the Powerwall—for only about 25% of the current German average market price. According to Tesla’s CEO Elon Musk, Germany is one of the key markets for their product. He has, however, not given numbers to support his statement. In this paper, we analyze the economic benefit of the Powerwall for end-users with respect to various influencing parameters: electricity price, aging characteristics of the batteries, topology of battery system coupling, subsidy schemes, and retrofitting of existing PV systems. Simulations show that three key-factors strongly influence economics: the price gap between electricity price and remuneration rate, the battery system’s investment cost, and the usable battery capacity. We reveal under which conditions a positive return on invest can be achieved and outline that the Powerwall could be a worthwhile investment in multiple, but not all, scenarios investigated. Resulting trends are generally transferrable to other home storage products. Full article
