Framing the environmental humanities
\"The concept of framing has long intrigued and troubled scholars in fields including philosophy, rhetoric, media studies and literary criticism. But framing also has rich implications for the environmental debate, urging us to reconsider how we understand the relationship between humans and their ecological environment, culture and nature.The contributors to this wide-ranging volume use the concept of framing to engage with key questions in environmental literature, history, politics, film, tv, and pedagogy. In so doing, they show that framing can serve as a valuable analytical tool connecting different academic discourses within the emergent interdisciplinary field of environmental humanities. No less importantly, they demonstrate how increased awareness of framing strategies and framing effects can help us move society in a more sustainable direction\"-- Provided by publisher.

Electrified methane reforming
Electrification of conventionally fired chemical reactors has the potential to reduce CO₂ emissions and provide flexible and compact heat generation. Here, we describe a disruptive approach to a fundamental process by integrating an electrically heated catalytic structure directly into a steam-methane–reforming (SMR) reactor for hydrogen production. Intimate contact between the electric heat source and the reaction site drives the reaction close to thermal equilibrium, increases catalyst utilization, and limits unwanted byproduct formation.The integrated design with small characteristic length scales allows compact reactor designs, potentially 100 times smaller than current reformer platforms. Electrification of SMR offers a strong platform for new reactor design, scale, and implementation opportunities. Implemented on a global scale, this could correspond to a reduction of nearly 1% of all CO₂ emissions.

The Incumbency Bonus Revisited: Causes and Consequences of Media Dominance
The literature on political actors’ media appearances has repeatedly documented the so-called incumbency bonus (that parties and politicians in government have more media coverage than those in the opposition). This bias is normally attributed to news criteria that reflect political power, such as relevance and the elite status of actors. Supplementing existing perspectives, this study puts forward a new explanation of the incumbency bonus. The article argues that variations in the media dominance of incumbents are the result of the interplay between journalistic norms and political context. Outside election campaigns, political news is driven by the ‘watch dog’ norm. Thus the media focus on societal problems, which produces a critical emphasis on incumbent actors. But when party competition intensifies, either during campaigns or when issues become salient, the norm of objective and impartial journalism results in a more balanced coverage where challengers increase their presence. The argument receives support through multivariate models of incumbent and challenger appearances in Danish radio news broadcasts over a twenty-year period. Finally, in terms of democratic implications, the importance of the watchdog norm challenges the assumption that the incumbency bonus constitutes an electoral asset. Since media dominance is closely related to government responsibility for all kinds of problems, incumbent support is found to dwindle with increased media appearances.

Monitoring of noble, signal and narrow-clawed crayfish using environmental DNA from freshwater samples
For several hundred years freshwater crayfish (Crustacea-Decapoda-Astacidea) have played an important ecological, cultural and culinary role in Scandinavia. However, many native populations of noble crayfish Astacus astacus have faced major declines during the last century, largely resulting from human assisted expansion of non-indigenous signal crayfish Pacifastacus leniusculus that carry and transmit the crayfish plague pathogen. In Denmark, also the non-indigenous narrow-clawed crayfish Astacus leptodactylus has expanded due to anthropogenic activities. Knowledge about crayfish distribution and early detection of non-indigenous and invasive species are crucial elements in successful conservation of indigenous crayfish. The use of environmental DNA (eDNA) extracted from water samples is a promising new tool for early and non-invasive detection of species in aquatic environments. In the present study, we have developed and tested quantitative PCR (qPCR) assays for species-specific detection and quantification of the three above mentioned crayfish species on the basis of mitochondrial cytochrome oxidase 1 (mtDNA-CO1), including separate assays for two clades of A. leptodactylus. The limit of detection (LOD) was experimentally established as 5 copies/PCR with two different approaches, and the limit of quantification (LOQ) were determined to 5 and 10 copies/PCR, respectively, depending on chosen approach. The assays detected crayfish in natural freshwater ecosystems with known populations of all three species, and show promising potentials for future monitoring of A. astacus, P. leniusculus and A. leptodactylus. However, the assays need further validation with data 1) comparing traditional and eDNA based estimates of abundance, and 2) representing a broader geographical range for the involved crayfish species.

The Bureaucracy and the Policy Agenda
The public administration literature has been dominated by questions about how politicians can control the bureaucracy’s application and implementation of laws at the back end of the policy process. Much less scholarly attention is devoted to the influence of the bureaucracy on the content and composition of the policy agenda at the front end of the process. Agenda setting is a fundamental aspect of politics, and this article examines the influence of the bureaucracy on the policy agenda and the conditions for this influence. The core proposition is that the policy agenda is larger and more diverse in political systems in which administrative professionals take up a larger share of the bureaucracy. This effect is expected to be mitigated by the involvement of elected representatives in the policymaking process. The empirical analysis supports these expectations. The findings are based on a time-series cross-section dataset from 98 Danish municipalities over 7 years containing a detailed coding of local council agendas and rich register data.

Implementation of neck/shoulder exercises for pain relief among industrial workers: A randomized controlled trial
Background
Although leisure-time physical activity is important for health, adherence to regular exercise is challenging for many adults. The workplace may provide an optimal setting to reach a large proportion of the adult population needing regular physical exercise. This study evaluates the effect of implementing strength training at the workplace on non-specific neck and shoulder pain among industrial workers.
Methods
Cluster-randomized controlled trial involving 537 adults from occupations with high prevalence of neck and shoulder pain (industrial production units). Participants were randomized to 20 weeks of high-intensity strength training for the neck and shoulders three times a week (n = 282) or a control group receiving advice to stay physically active (n = 255). The strength training program followed principles of progressive overload and periodization. The primary outcome was changes in self-reported neck and shoulder pain intensity (scale 0-9).
Results
85% of the participants followed the strength training program on a weekly basis. In the training group compared with the control group, neck pain intensity decreased significantly (-0.6, 95% CI -1.0 to -0.1) and shoulder pain intensity tended to decrease (-0.2, 95% CI -0.5 to 0.1, P = 0.07). For pain-cases at baseline (pain intensity > = 3) the odds ratio - in the training group compared with the control group - for being a non-case at follow-up (pain intensity < 3) was 2.0 (95% CI 1.0 to 4.2) for the neck and 3.9 (95% CI 1.7 to 9.4) for the shoulders.
Conclusion
High-intensity strength training relying on principles of progressive overload can be successfully implemented at industrial workplaces, and results in significant reductions of neck and shoulder pain.

Coping with the unforeseen: bounded rationality and bureaucratic responses to the COVID-19 crisis
The outbreak of COVID-19 unleashed a severe crisis in society. The suddenness and speed with which the disease spread into a global pandemic makes it an outstanding case for showing how bureaucracy acts in response to a crisis marked by uncertainty and urgency. This article focuses on the role played by the central government bureaucracy in preparing and enacting the Danish government’s response to the COVID-19 crisis. It is based on full access to internal government files related to crisis management during the winter and spring of 2020. These files include memos, e-mails, decision notes, and draft decisions from key civil servants. The article demonstrates the strength of the theory of bounded rationality when it comes to analyzing the interaction between top civil servants and political executives. Moreover, it shows how administrative and political executives can mold a governmental organization to overcome the inertia inherent in bureaucratic organization and procedures.

Public sector reform and blame avoidance effects
Blame avoidance has often been claimed to be an important rationale behind changes in the organisation of the public sector, but very few studies have examined whether and how public attribution of responsibility is actually affected by such reforms. For instance, how do changes in the formal allocation of authority affect public attribution of blame when things go wrong? Is the effect immediate or delayed? To advance our understanding of such questions, this paper presents an analysis of blame and credit attribution in more than 1,200 newspaper articles about health-care-related issues in Norway before and after the major Norwegian hospital reform from 2002. The central empirical finding of the article is that central state-level authorities in Norway were attributed less blame in media coverage of health-care problems after the reform than before the reform. The shift is delayed, but substantial and robust to various modifications in model estimations.
