This contradicts the common belief in prevalent economies of scale for such e-businesses. We, however, rely on a comprehensive analysis of a dataset where we have collected and combined publicly available and audited financial data, mostly coming from Netflix's 10-K reports. In our analysis we employ several user-cost models, namely a baseline linear model, a power law model, an exponential model, and a logarithmic model. Such models often appear (in different variations) in economics literature, but are almost inexistent in the rhetoric around SVOD business models. Corroborating the applications of all these mathematical models on the financial data of Netflix identifies a super-linear increase in costs with expanding user basis, indicating the rising per-user costs that defines diseconomies of scale. These findings provide critical insights into SVOD service scalability, challenging prevailing assumptions and informing expectations about cost dynamics in this industry.</p>
Notebook with simulation model for sufficiency policy futures paper
No full text<p>Abstract of the paper:<br><br> To ensure a positive environmental impact of information and communication technologies (ICT), it is imperative to address their negative consequences. While efforts to enhance efficiency and ensure consistency in ICT production are essential, this study suggests that sufficiency measures are indispensable. This research provides evidence for this claim by developing a simulation model applied to studying the environmental impact of the interaction of a population, a government and a major technology producer, within four environmental policy scenarios. The results demonstrate that sufficiency measures are not only highly effective in mitigating emissions and e-waste but also represent a necessary condition for achieving our climate goals in as little time as possible. The model provided in this research can serve as the basis of future policy studies and could have the potential to become a decision-support mechanism for policymakers.</p>

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Limiting rebound effect in streaming services: A simulation study
Full text linkRebound effects are gaining attention in the sustainability and ICT literature. Although several studies have addressed possible measures for reducing rebound effects, the literature on modelling and simulating the mechanisms of those measures remains scarce, especially in the context of ICT. This study develops a simulation model, based on compartmental methods, that examines two taxation strategies aimed at reducing rebound effects in subscription-based streaming services. In addition to a more conventional environmental impact tax (e.g., carbon tax), a Rebound tax that 'confiscates' part of the efficiency gains is implemented. Results suggest that, compared with the Environmental tax, applying a Rebound tax would be more beneficial for companies. In the two studied scenarios, the final revenues are higher for a similar environmental impact when the tax applied is the Rebound one. Implementing both taxes at the same time offers the greatest benefits in terms of reduction of impact, but it can also result in excessive financial pressure on the company.submittedVersio
Environmental Taxation for Reducing Emissions from Online Advertisement in Music Streaming Services
Full text linkAs usage of music streaming services grows, so does their impact on the environment. Adopting a freemium business model, a model that combines a subscription-based system with an ad-supported limited free version increases that impact. In this paper, we show that a tax on the environmental impact of music streaming services (e.g., a carbon tax) can promote a more environmentally and economically sustainable subscription-only, premium business model. We develop a simulation model using compartmental methods, with an implementation in Python, that represents the competition between a freemium service and a premium service, in two different market stages (young and mature markets). We show that an environmental tax is able to reduce overall environmental impact, promote more sustainable alternatives, and increase benefits due to higher returns from premium subscribers.acceptedVersio
