Emissions from aviation will continue to increase in the future, in contradiction of global climate policy objectives. Yet, airlines and airline organisations suggest that aviation will become climatically sustainable. This paper investigates this paradox by reviewing fuel-efficiency gains since the 1960s in comparison to aviation growth, and by linking these results to technology discourses, based on a two-tiered approach tracing technology-focused discourses over 20 years (1994-2013). Findings indicate that a wide range of solutions to growing emissions from aviation have been presented by industry, hyped in global media, and subsequently vanished to be replaced by new technology discourses. Redundant discourses often linger in the public domain, where they continue to be associated with industry aspirations of 'sustainable aviation' and 'zero-emission flight'. The paper highlights and discusses a number of technology discourses that constitute 'technology myths', and the role these 'myths' may be playing in the enduring but flawed promise of sustainable aviation. We conclude that technology myths require policy-makers to interpret and take into account technical uncertainty, which may result in inaction that continues to delay much needed progress in climate policy for aviation.

This overview paper examines three areas crucial to understanding why, despite clear scientific evidence for the growing environmental impacts of tourism transport, there is large-scale inertia in structural transitions and a lack of political will to enact meaningful sustainable mobility policies. These include the importance of addressing socio-technical factors, barriers posed by “technology myths” and the need to overcome “transport taboos” in policy-making. The paper seeks pathways to sustainable mobility by bridging the science–policy gap between academic research and researchers, and policy-makers and practitioners. It introduces key papers presented at the Freiburg 2014 workshop, covering the case for researcher engagement using advocacy and participatory approaches, the role of universities in creating their own social mobility policies, the power of social mechanisms encouraging long-haul travel, issues in consumer responsibility development, industry self-regulation and the operation of realpolitik decision-making and implementation inside formal and informal destination-based mobility partnerships. Overall, the paper argues that governments and the tourism and transport industries must take a more cautious approach to the technological optimism that fosters policy inertia, and that policy-makers must take a more open approach to implementing sustainable transport policies. A research agenda for desirable transport futures is suggested.

De implementatie van blended learning – waarbij fysiek leren wordt gecombineerd met online leren – staat bij veel onderwijsinstellingen hoog op de agenda, om activeren, intensiveren, flexibiliseren, differentiëren en/of personaliseren mogelijk te maken (Bos, 2022). Als gevolg hiervan krijgt de online leeromgeving binnen onderwijsinstellingen een steeds nadrukkelijkere rol. Om te komen tot betekenisvol leren in deze online leeromgeving (vaak in de vorm van een leermanagementsysteem, ook wel LMS genoemd), is het belangrijk dat studenten hierin actief aan de slag gaan met de aangeboden onderwijsinhoud en geïnteresseerd en gemotiveerd zijn om dit te (gaan) doen (Michael, 2006; Alhazmi & Rahman, 2012; Derboven et al., 2017; Grant-Smith et al., 2019). Echter, in de praktijk blijkt dat lang niet altijd sprake is van deze gewenste student engagement. Bijlage 1: Dit artikel geeft de resultaten weer van een onderzoek naar mogelijkheden om student engagement in het LMS te vergroten. Deze resultaten zijn tevens samengevat in twee overzichtelijke infographics. Bijlage 2: Infographic 1 omvat het gehele overzicht van de (mogelijk) te implementeren ontwerpprincipes. Bijlage 3: Infographic 2 bevat een stappenplan voor docenten om hun LMS te analyseren en te optimaliseren (laaghangend fruit).

There is increasing evidence that humans are not living sustainably. There are three major drivers of the unsustainable approach: population, consumption and the growth economy. There is widespread denial about these issues, but they clearly need to be addressed if we are to achieve any of the possible sustainable futures. The first and second versions of the ‘World Scientists Warning to Humanity’ both highlight the problem of increasing human population, as do the IPCC and IPBES reports. However, all have been largely ignored. The size of an ecologically sustainable global population is considered, taking into account the implications of increasing per capita consumption. The paper then discusses the reasons why society and academia largely ignore overpopulation. The claim that discussing overpopulation is ‘anti-human’ is refuted. Causal Layered Analysis is used to examine why society ignores data that do not fit with its myths and metaphors, and how such denial is leading society towards collapse. Non-coercive solutions are then considered to reach an ecologically-sustainable human population. LinkedIn: https://www.linkedin.com/in/helenkopnina/

In less than two years, the concept of overtourism has come to prominence as one of the most discussed issues with regards to tourism in popular media and, increasingly, academia. In spite of its popularity, the term is still not clearly delineated and remains open to multiple interpretations. The current paper aims to provide more clarity with regard to what overtourism entails by placing the concept in a historical context and presenting results from a qualitative investigation among 80 stakeholders in 13 European cities. Results highlight that overtourism describes an issue that is multidimensional and complex. Not only are the issues caused by tourism and nontourism stakeholders, but they should also be viewed in the context of wider societal and city developments. The article concludes by arguing that while the debate on overtourism has drawn attention again to the old problem of managing negative tourism impacts, it is not well conceptualized. Seven overtourism myths are identified that may inhibit a well-rounded understanding of the concept. To further a contextualized understanding of overtourism, the paper calls for researchers from other disciplines to engage with the topic to come to new insights.

Social networks and news outlets use recommender systems to distribute information and suggest news to their users. These algorithms are an attractive solution to deal with the massive amount of content on the web [6]. However, some organisations prioritise retention and maximisation of the number of access, which can be incompatible with values like the diversity of content and transparency. In recent years critics have warned of the dangers of algorithmic curation. The term filter bubbles, coined by the internet activist Eli Pariser [1], describes the outcome of pre-selected personalisation, where users are trapped in a bubble of similar contents. Pariser warns that it is not the user but the algorithm that curates and selects interesting topics to watch or read. Still, there is disagreement about the consequences for individuals and society. Research on the existence of filter bubbles is inconclusive. Fletcher in [5], claims that the term filter bubbles is an oversimplification of a much more complex system involving cognitive processes and social and technological interactions. And most of the empirical studies indicate that algorithmic recommendations have not locked large segments of the audience into bubbles [3] [6]. We built an agent-based simulation tool to study the dynamic and complex interplay between individual choices and social and technological interaction. The model includes different recommendation algorithms and a range of cognitive filters that can simulate different social network dynamics. The cognitive filters are based on the triple-filter bubble model [2]. The tool can be used to understand under which circumstances algorithmic filtering and social network dynamics affect users' innate opinions and which interventions on recommender systems can mitigate adverse side effects like the presence of filter bubbles. The resulting tool is an open-source interactive web interface, allowing the simulation with different parameters such as users' characteristics, social networks and recommender system settings (see Fig. 1). The ABM model, implemented in Python Mesa [4], allows users to visualise, compare and analyse the consequence of combining various factors. Experiment results are similar to the ones published in the Triple Filter Bubble paper [2]. The novelty is the option to use a real collaborative-filter recommendation system and a new metric to measure the distance between users' innate and final opinions. We observed that slight modifications in the recommendation system, exposing items within the boundaries of users' latitude of acceptance, could increase content diversity.References 1.

Aim: There is often a gap between the ideal of involving older persons iteratively throughout the design process of digital technology, and actual practice. Until now, the lens of ageism has not been applied to address this gap. The goals of this study were: to voice the perspectives and experiences of older persons who participated in co-designing regarding the design process; their perceived role in co-designing and intergenerational interaction with the designers; and apparent manifestations of ageism that potentially influence the design of digital technology. Methods: Twenty-one older persons participated in three focus groups. Five themes were identified using thematic analysis which combined a critical ageism ‘lens’ deductive approach and an inductive approach. Results: Ageism was experienced by participants in their daily lives and interactions with the designers during the design process. Negative images of ageing were pointed out as a potential influencing factor on design decisions. Nevertheless, positive experiences of inclusive design pointed out the importance of “partnership” in the design process. Participants defined the “ultimate partnership” in co-designing as processes in which they were involved from the beginning, iteratively, in a participatory approach. Such processes were perceived as leading to successful design outcomes, which they would like to use, and reduced intergenerational tension. Conclusions: This study highlights the potential role of ageism as a detrimental factor in how digital technologies are designed. Viewing older persons as partners in co-designing and aspiring to more inclusive design processes may promote designing technologies that are needed, wanted and used.

Nowadays “facts” and thus “truth” seems inescapable: there 's hardly any room for imagination, let alone for myths. However, we must not confuse facts with truth. Newton, for example, would never have come to his deep knowledge if he had not looked past the facts. There are never enough facts, if you look harder there are always other facts. It is argued that modern information and communication technology (ICT) has made the world seemingly transparent, and that 's why especially in this time “fake news” has become such a big theme.
