    Background and aims Wastewater‐based epidemiology is an additional indicator of drug use that is gaining reliability to complement the current established panel of indicators. The aims of this study were to: (i) assess spatial and temporal trends of population‐normalized mass loads of benzoylecgonine, amphetamine, methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA) in raw wastewater over 7 years (2011–17); (ii) address overall drug use by estimating the average number of combined doses consumed per day in each city; and (iii) compare these with existing prevalence and seizure data. Design Analysis of daily raw wastewater composite samples collected over 1 week per year from 2011 to 2017. Setting and Participants Catchment areas of 143 wastewater treatment plants in 120 cities in 37 countries. Measurements Parent substances (amphetamine, methamphetamine and MDMA) and the metabolites of cocaine (benzoylecgonine) and of Δ9‐tetrahydrocannabinol (11‐nor‐9‐carboxy‐Δ9‐tetrahydrocannabinol) were measured in wastewater using liquid chromatography–tandem mass spectrometry. Daily mass loads (mg/day) were normalized to catchment population (mg/1000 people/day) and converted to the number of combined doses consumed per day. Spatial differences were assessed world‐wide, and temporal trends were discerned at European level by comparing 2011–13 drug loads versus 2014–17 loads. Findings Benzoylecgonine was the stimulant metabolite detected at higher loads in southern and western Europe, and amphetamine, MDMA and methamphetamine in East and North–Central Europe. In other continents, methamphetamine showed the highest levels in the United States and Australia and benzoylecgonine in South America. During the reporting period, benzoylecgonine loads increased in general across Europe, amphetamine and methamphetamine levels fluctuated and MDMA underwent an intermittent upsurge. Conclusions The analysis of wastewater to quantify drug loads provides near real‐time drug use estimates that globally correspond to prevalence and seizure data.

    In this study, we examine associations between the quality of teacher-child interactions and infant outcomes during their first months in Portuguese childcare centers. Participants were 90 infants, their mothers and their teachers. A set of multiple regression models were conducted to determine whether classroom quality related to active engagement and non-engagement and to adaptive behavior six months later, controlling for important covariates, namely developmental age, child temperament, mothers’ education, and home quality. Results showed that, in higher quality classrooms, infants spent more time actively engaged, less time non-engaged and six months later were rated as having higher levels of adaptive behaviors. Findings provide further evidence for the need to better support teachers in fostering infant active engagement and unfolding capacities as part of high-quality daily experiences in childcare.

    The Paralympic Games have become a relevant social and communication tool for the enhancement of global awareness and understanding of disability. The increasing visibility of this kind of global sports event, as well as the efforts of public authorities to make their host cities more accessible, evidence a relevant shift to new urban barrier-free experiences and discourses concerning disability. This research is guided by an exploratory case study approach to assess the disability representation and narratives within the context of the 2020 Tokyo Paralympic Games. The examination of some innovative communication strategies fostering the visibility of disability reveals a series of effective practices implemented in Japan. The focus on the personification of para-athletes, the celebration of public events to experience first-hand para-sports disciplines, as well as the engagement of school-children and young people in para-sports initiatives are predominant in the communication efforts of Tokyo 2020 in the pre-games period.

    Delivering Smart Governance in a Future City: The Case of Glasgow

    Publicação

    Outros Autores: Webster, C. William R.
    In 2013, Glasgow City Council received significant funding to develop innovative smart city applications, including the delivery of new electronic public services and the co-production of governance. This case study examines the processes that underpin the ways in which the ‘Future City Glasgow programme’ delivered ‘smart governance’, in the context of a regenerating post-industrial city. We assess the contribution of smart city technologies and data collection and monitoring processes designed to facilitate citizen engagement and sustainable governance practices. The Future City Glasgow programme ran from 2013‒2015, and included the Open Glasgow project, and ‘Demonstrator Projects’ of: Energy Efficiency; Intelligent Street Lighting; Active Travel; and, Integrated Social Transport. Opportunities arose from these demonstrators for developing co-production and legacy initiatives. The case study provides insight into the ways in which citizens and local communities in Glasgow have been engaged in governance processes. This engagement has taken place via traditional and innovative smart city technologies, and in particular in relation to policy formulation, service design and delivery. It finds that the co-creation of governance is shaped by vested interests, that engagement is fragmented and partial, but at the same time new technologies, social media and shared learning opportunities offer innovative new ways for some citizens to influence local governance.

    Remixing News: Appropriation and Authorship in Finnish Counter-Media

    Publicação
    por Seuri, Olli
    Outros Autores: Ramstedt, Kim
    This article outlines a first attempt at analysing counter-media publishing through the lens of remix theory. We concentrate on two key concepts—appropriation and authorship—which have a permanent standing in the remix research literature. To support our theoretical analysis, we investigate the coverage of two cases in the Finnish right-wing counter-media online publication MV-lehti. Our findings enable new readings on the nature of both counter-media work and remix culture. In fact, counter-media publishing leans more in the direction of remix culture—which is based on the act of using pre-existing materials to produce something new—than towards traditional journalistic convention, with its rules and ethical guidelines. MV-lehti’s practice of combining and layering different material is discernibly political, often resembling media activism. Our study provides the argument that counter to the utopian democratising assumptions of remix culture, the proliferation of remix practices has also given antidemocratic actors the means to challenge collectively and institutionally supported ideas of knowledge and justice. Counter-media publishing is perhaps democratising in that it offers the means to participate, but these antagonistic actors also remix news to undermine liberal-democratic ideals and social justice. Evidently, remix practices can be co-opted for a reactionary agenda.

    ProPublica’s Data Journalism: How Multidisciplinary Teams and Hybrid Profiles Create Impactful Data Stories

    Publicação
    por de-Lima-Santos, Mathias-Felipe
    Despite growing interest in the emergence of technologies in journalistic practices, especially from the production perspective, there is still very little research on organizational structures and professional culture in relation to the deployment of these technologies. Drawing on six interviews and observation in staff meetings, this study aims to explore the nuances behind the professional roles of data journalists and how these relate to structural aspects of news organizations. The study focuses on the case of ProPublica, a news organization internationally renowned for its global excellence in data stories. This work considers boundary-making in the context of journalism and focuses on new professional roles in the news industry to produce a hybrid ethnography study based on qualitative data collected immediately before the Covid-19 pandemic hit the United States. The findings reveal the importance of hybrid profiles at ProPublica. While some journalists have had to expand their knowledge to learn more about new areas, such as coding and design, some non-journalistic professionals have had to develop writing skills, and this blurring of traditional boundaries forms an important aspect of ProPublica’s professional culture. The structure of the organization, divided into two teams engaged in cross-sector activities, helps to promote data skills and collaboration with other journalists, which also serves to mitigate any individual lack of experience on certain topics. The article concludes by suggesting that the growing importance of these new professional roles has broader implications for the development of data skills in the newsroom, and also discusses the limitations that can arise from the increasing overlap between journalistic and non-journalistic roles.

    Mobile Journalists as Traceable Data Objects: Surveillance Capitalism and Responsible Innovation in Mobile Journalism

    Publicação
    por Salzmann, Anja
    Outros Autores: Guribye, Frode; Gynnild, Astrid
    This article discusses how Shosana Zuboff’s critical theory of surveillance capitalism may help to understand and underpin responsible practice and innovation in mobile journalism. Zuboff conceptualizes surveillance capitalism as a new economic logic made possible by ICT and its architecture for extracting and trading data products of user behavior and preferences. Surveillance is, through these new technologies, built into the fabric of our economic system and, according to Zuboff, appears as deeply anti-democratic and a threat to human sovereignty, dignity, and autonomy. In Europe, the framework of responsible research and innovation is promoted as an approach and a meta-concept that should inform practice and policy for research and innovation to align with societal values and democratic principles. Within this approach, ICT is framed as a risk technology. As innovation in mobile journalism is inextricably tied to the technologies and infrastructure of smartphones and social media platforms, the apparent question would be how we can envision responsible innovation in this area. Zuboff provides a critical perspective to study how this architecture of surveillance impedes the practice of mobile journalism. While the wide adoption of smartphones as a key tool for both producing and consuming news has great potential for innovation, it can also feed behavioral data into the supply chain of surveillance capitalism. We discuss how potentially harmful implications can be met on an individual and organizational level to contribute to a more responsible adoption of mobile technologies in journalism.

    A Graph-Learning Approach for Detecting Moral Conflict in Movie Scripts

    Publicação

    Outros Autores: Fisher, Jacob Taylor; Weber, René
    Moral conflict is central to appealing narratives, but no methodology exists for computationally extracting moral conflict from narratives at scale. In this article, we present an approach combining tools from social network analysis and natural language processing with recent theoretical advancements in the Model of Intuitive Morality and Exemplars. This approach considers narratives in terms of a network of dynamically evolving relationships between characters. We apply this method in order to analyze 894 movie scripts encompassing 82,195 scenes, showing that scenes containing moral conflict between central characters can be identified using changes in connectivity patterns between network modules. Furthermore, we derive computational models for standardizing moral conflict measurements. Our results suggest that this method can accurately extract moral conflict from a diverse collection of movie scripts. We provide a theoretical integration of our method into the larger milieu of storytelling and entertainment research, illuminating future research trajectories at the intersection of computational communication research and media psychology.

    Advancing Research into Dark Participation

    Publicação
    por Westlund, Oscar
    Dark participation is and should be an essential concept for scholars, students and beyond, considering how widespread disinformation, online harassment, hate speech, media manipulation etc. has become in contemporary society. This commentary engages with the contributions to this timely thematic issue, which advance scholarship into dark participation associated with news and misinformation as well as hate in a worthwhile way. The commentary closes with a call for further research into four main areas: 1) the motivations that drive dark participation behaviors by individuals and coordinated groups; 2) how these individuals and groups exploit platforms and technologies for diverse forms of dark participation; 3) how news publishers, journalists, fact-checkers, platform companies and authorities are dealing with dark participation; and 4) how the public can advance their media literacy for digital media in order to better deal with dark participation. Authorities must advance and broaden their approaches focused on schools and libraries, and may also use emerging technologies in doing so.

    Obesity, and particularly childhood obesity, is considered an epidemic by the WHO because of the health problems it causes and its impact on the lives and environment of those who suffer from it. In this article, the term “obesogenic features” refers to the set of supposedly aggravating risk factors that could intensify the proven effect on minors of exposure to food-related media content. The article explores the characteristics of food-related content in YouTube videos aimed at children, with the objective of identifying videos that pose a high risk due to the presence of obesogenic arguments, as well as videos with innovative media trends. It presents an exploratory study of 293 videos (22 hr 41 min) aimed at children and containing food and/or food brands, posted from May 2020 to April 2021 on 28 YouTube channels of food brands and child YouTubers with the largest numbers of subscribers. Child YouTubers often appear to explicitly promote calorie intake as a diet alternative and to disseminate content in which the presence of low-nutrition foods undermines childhood obesity prevention policies. The sensitivity of this target audience and the highly emotional nature of the formats in which messages with obesogenic features appear, such as “challenges,” point to an urgent need to adopt ethical standards and legal measures to regulate such content.
