description: We show that Renormalization Group extensions of the Einstein-Hilbert action for large scale physics are not, in general, a particular case of standard Scalar-Tensor (ST) gravity. We present a new class of ST actions, in which the potential is not necessarily fixed at the action level, and show that this extended ST theory formally contains the Renormalization Group case. We also propose here a Renormalization Group scale setting identification that is explicitly covariant and valid for arbitrary relativistic fluids.

description: Physiological effects of cellular hypoxia are sensed by prolyl hydroxylase (PHD) enzymes which regulate HIFs. Genetic interventions on HIF/PHD pathways reveal multiple phenotypes that extend the known biology of hypoxia. Recent studies unexpectedly implicate HIF in aspects of multiple immune and inflammatory pathways. However such studies are often limited by systemic lethal effects and/or use tissue-specific recombination systems, which are inherently irreversible, un-physiologically restricted and difficult to time. To study these processes better we developed recombinant mice which express tetracycline-regulated shRNAs broadly targeting the main components of the HIF/PHD pathway, permitting timed bi-directional intervention. We have shown that stabilization of HIF levels in adult mice through PHD2 enzyme silencing by RNA interference, or inducible recombination of floxed alleles, results in multi-lineage leukocytosis and features of autoimmunity. This phenotype was rapidly normalized on re-establishment of the hypoxia-sensing machinery when shRNA expression was discontinued. In both situations these effects were mediated principally through the Hif2a isoform. Assessment of cells bearing regulatory T cell markers from these mice revealed defective function and pro-inflammatory effects in vivo. We believe our findings have shown a new role for the PHD2/Hif2a couple in the reversible regulation of T cell and immune activity.
Study towards the detection of virulence factor genes in diarrhoeagenic Escherichia coli

description: Diarrhea remains one of the main sources of mortality and morbidity in today's world and a significant causal agent is diarrheagenic Escherichia coli. These bacteria are a particular problem in developing countries although traveler's diarrhea and hemorrhagic colitis are also a problem in developed countries (Nataro et al, 1998). In the Northern Territory (NT) of Australia, Aboriginal children are greatly exposed to: bacterial pathogens in contaminated food and water; overcrowded living conditions with high rates of faecal-oral transmission; frequent intestinal infections;and small bowel bacterial contamination which result in more frequent diarrheal episodes (Brewster et al, 2002). This study was developed to provide new information about the prevalence of diarrheagenic E. coli virulence factors, specially EAggEC and EIEC which have been suspected in sporadic infections of diarrheal and non-diarrheal Aboriginal children(<6 years old) admitted to the Royal Darwin Hospital. The importance of virulence factors in diarrheagenic E. coli as a possible cause of acute and chronic diarrhea in Aboriginal children was investigated. From 128 bacterial samples collected from 72 Aboriginal children admitted to hospital, 64 with diarrhea and 8 healthy controls, broth cultures were prepared and processed for DNA extractions and used in polymerase chain reactions (PCR). PCR made possible thedetection of (aafl, aaj3, EAggEC, DAEC, EJEC, hlyA, eaeA, bfpA, stxl and stx2)virulence factor genes used to identify specific diarrheagenic E. coli types. Positive PCR bacterial samples of all identified diarrheagenic E. coli were then statistically analysed to see the prevalence of their virulence factors. Also, positive PCR samples of EJEC and EAggEC were then tested by using the restriction fragment length of polymorphism (RFLP) and randomly amplified polymorphic DNA (RAPD)analysis. From this study, it was found that both EAggEC and EPEC were the most prevalent potential bacteria found in Aboriginal children with diarrhea and as well in healthy controls. Prevalence of EJEC bacteria suspected to cause infection in Aboriginal children was not significantly found in our study. Also, RFLP and RAPD results revealed that diarrhea cases in Aboriginal children could possibly be associated with potentially EAggEC carrying multiple virulence factors or harboured by different AA mobile plasmid. Information in this study will play an important role in the future epidemiological study of diarrhoea in Aboriginal children. And subsequently be used as a helpful source of information in understanding what etiological agents are prevalent in the Aboriginal community children admitted to the hospital.

description: We prove that the refined approach -- our extension of the Yakovenko et al. formalism -- is universal in the sense that it describes well both household incomes in the European Union and the individual incomes in the United States for social classes of any income. This formalism allowed the study of the impact of the recent world-wide financial crisis on the annual incomes of different social classes. Hence, we indicate the existence of a possible precursor of a market crisis. Besides, we find the most painful impact of the crisis on incomes of all social classes.

description: China has sought to address water pollution in the last decade by introducing a wide range of laws and regulations (Table S1), which led to nationwide water quality improvement. However, recent quantitative assessment of progress toward Sustainable Development Goals (SDGs) in China suggests that some SDGs underpinning goals for water pollution and biodiversity have not been met. Specifically, tests on water quality improvement in lakes have had contradictory results, leading to confusion about water quality improvement in China.

description: It has been pointed out that the null energy condition can be violated stably in some non-canonical scalar-field theories. This allows us to consider the Galilean Genesis scenario in which the universe starts expanding from Minkowski spacetime and hence is free from the initial singularity. We use this scenario to study the early-time completion of inflation, pushing forward the recent idea of Pirtskhalava et al. We present a generic form of the Lagrangian governing the background and perturbation dynamics in the Genesis phase, the subsequent inflationary phase, and the graceful exit from inflation, as opposed to employing the effective field theory approach. Our Lagrangian belongs to a more general class of scalar-tensor theories than the Horndeski theory and Gleyzes-Langlois-Piazza-Vernizzi generalization, but still has the same number of the propagating degrees of freedom, and thus can avoid Ostrogradski instabilities. We investigate the generation and evolution of primordial perturbations in this scenario and show that one can indeed construct a stable model of inflation preceded by (generalized) Galilean Genesis.

description: Estuaries regulate transport of dissolved organic carbon (DOC) from land to ocean. Export of terrestrial DOC from coastal watersheds is exacerbated by increasing major rainfall and storm events and human activities, leading to pulses of DOC that are shunted through rivers downstream to estuaries. Despite an upward trend of extreme events, the fate of the pulsed terrestrial DOC in estuaries remains unclear. We analyzed the effects of seven major tropical cyclones (TC) from 1999 to 2017 on the quantity and fate of DOC in the Neuse River Estuary (NC, USA). Significant TC-induced increases in DOC were observed throughout the estuary; the increase lasting from around 50 d at head-of-tide to over 6 months in lower estuary. Our results suggest that pulsed terrestrial DOC associated with TCs temporarily overwhelms the estuarine filter's abiotic and biotic degradation capacity under such high flow events, enhancing the shunt of terrestrial carbon to the coastal ocean.

description: We investigate the evolutionary aspects of some integrable soliton models whose Lagrangians are derived from the pullback of a volume-form to a two-dimensional target space. These models are known to have infinitely many conserved quantities and support various types of exact analytic solutions with nontrivial topology. In particular, we show that, in spite of the fact that they admit nice smooth solutions, wave propagation about these solutions will always be ill-posed. This is related to the fact that the corresponding Euler-Lagrange equations are not of hyperbolic type.

How do bubble-bubble and bubble-conduit interactions affect gas mass transport in a magmatic conduit?
Creators: name: Roscoe, Matt
Publisher: name: Lancaster University
Year: 2023

description: As magma ascends, the bubbles that develop within it affect eruption style and, thus, understanding the possible configuration of bubbles in volcanic systems ultimately helps in mitigating volcanic hazard. While conduit models exist to describe the development of gas bubbles in basaltic systems, these do not take into consideration the effect of bubbles acting as groups on length scales comparable to multiple bubble diameters, nor do they consider the impact of non-vertical magma conduits. These effects were explored using a series of analogue experiments to identify and begin to quantify bubble grouping behaviour in a viscous liquid and the effect of inclining the constraining walls of a gas bubble-viscous liquid system. The main findings were that 1) bubbles have a tendency to self-organise into groups of greater bubble number density, 2) groups of bubbles act together such that their rise speed is typically 2-5 times greater than the buoyant rise speed of individual bubbles, 3) bubble interactions tend to result in vertical size stratification, and 4) the inclination of a conduit radically alters the spatial distribution across the width of the conduit even at low (

Fracking magma: A field and experimental investigation of hydrofracturing in volcanic systems
Creators: name: Unwin, Holly
Publisher: name: Lancaster University
Year: 2023

description: Rhyolite eruptions typically begin with the explosive ejection of pyroclastic material, with the potential to form widespread ash plumes that can have worldwide impacts. These eruptions then transition to effusive activity, characterised by the gentler emission of lava. Due to the scarcity of rhyolite eruptions, the processes that control the dynamics of these eruptions are poorly understood, despite the potentially significant hazards. Tuffisites — pyroclast-filled fractures that form within and adjacent to silicic volcanic vents at different stages of an eruption — are thought to provide insights into the processes that control the formation and evolution of silicic volcanic vents, and therefore influence the dynamics of a resulting eruption. Tuffisites are more permeable than the surrounding country rock, leading to suggestions that tuffisites may be able to allow significant volumes of gas to escape the conduit, potentially reducing sufficient excess pressure to moderate the explosivity of an eruption and change its hazards. This thesis aims to uncover new details about the formation of tuffisites and constrain whether tuffisite-enabled outgassing might be significant on the timescale of an eruption (Animation 1, Appendix A.1). By extrapolating this knowledge of tuffisite formation to the evolution of silicic vents, this thesis then aims to use tuffisites to gain insights into the processes that control eruption dynamics. This work finds that tuffisites form throughout the evolution of silicic vents, above the level of fragmentation in the conduit. Tuffisites can form by the injection of multiple pulses of pyroclastic material into a fracture, and therefore can be interpreted as records of fluctuations of the fluid pressure within the volcanic conduit during an eruption. By combining particle-size distributions with porosity and permeability measurements, this thesis finds that the opening of the fractures that host tuffisites can allow for the pulsed escape of large volumes of gas from the volcanic conduit, potentially influencing the dynamics of an eruption.

description: Recent cosmological observations are in good agreement with the scalar spectral index $n_s$ with $n_s-1\sim -2/N$, where $N$ is the number of e-foldings. Quadratic chaotic model, Starobinsky model and Higgs inflation or $α$-attractors connecting them are typical examples predicting such a relation. We consider the problem in the opposite: given $n_s$ as a function of $N$, what is the inflaton potential $V(ϕ)$. We find that for $n_s-1=-2/N$, $V(ϕ)$ is either $\tanh^2(γϕ/2)$ ("T-model") or $ϕ^2$ (chaotic inflation) to the leading order in the slow-roll approximation. $γ$ is the ratio of $1/V$ at $N\rightarrow \infty$ to the slope of $1/V$ at a finite $N$ and is related to "$α$" in the $α$-attractors by $γ^2=2/3α$. The tensor-to-scalar ratio $r$ is $r=8/N(γ^2 N +1) $. The implications for the reheating temperature are also discussed. We also derive formulas for $n_s-1=-p/N$. We find that if the potential is bounded from above, only $p>1$ is allowed. Although $r$ depends on a parameter, the running of the spectral index is independent of it, which can be used as a consistency check of the assumed relation of $n_s(N)$.

description: Trait-based approaches provide a mechanistic framework crossing scales from cellular traits to community dynamics, while ecological stoichiometry applies first principles to understand how the balance of energy and elements shape ecological interactions. However, few studies have explicitly linked both frameworks. In this study, we tested the stoichiometric regulation of a number of carbon (C) based (e.g., extracellular polysaccharides and colony formation) and nitrogen (N) containing traits (i.e., chlorophyll a, phycocyanin, and gas vesicle content) in cyanobacteria in laboratory experiments and in the field. We exposed the cosmopolitan colony forming freshwater cyanobacterium Microcystis sp. in batch experiments to light, N and phosphorus (P) limitation, and enhanced CO2 levels, and assessed the regulation of these traits. Cyanobacterial traits followed stoichiometrically predictable patterns, where N containing traits increased with cellular N content, and decreased with increasing C : N ratios. C-based traits increased with cellular C content and C : N ratios under nutrient, particularly N, limitation. The pattern of colony formation was confirmed with field data from Lake Taihu (China), showing an increase in colony size when N was limiting and N : P ratios were low. These findings demonstrate how an explicit coupling of trait-based approaches to ecological stoichiometry can support our mechanistic understanding of responses of cyanobacteria toward shifts in resource availability.
Effects of Ferrous Iron and Hydrogen Sulfide on Nitrate Reduction in the Sediments of an Estuary Experiencing Hypoxia

Publisher: name: Springer

description: Hypoxia is common feature of eutrophic estuaries and semi-enclosed seas globally. One of the key factors driving hypoxia is nitrogen pollution. To gain more insight into the effects of hypoxia on estuarine nitrogen cycling, we measured potential nitrate reduction rates at different salinities and levels of hypoxia in a eutrophic temperate microtidal estuary, the Neuse River Estuary, North Carolina, USA. We also tested the effect of hydrogen sulfide and ferrous iron additions on the nitrate reduction pathways. Overall, DNRA dominated over denitrification in this periodically hypoxic estuary and there was no correlation between the potential nitrate reduction rates, salinity, or dissolved oxygen. However, when hypoxia lasted several months, denitrification capacity was almost completely lost, and nearly all nitrate added to the sediment was reduced via DNRA. Additions of hydrogen sulfide stimulated DNRA over denitrification. Additions of ferrous iron stimulated nitrate consumption; however, the end product of nitrate consumption was not clear. Interestingly, substantial nitrous oxide formation occurred in sediments that had experienced prolonged hypoxia and were amended with nitrate. Given expanding hypoxia predicted with climate change scenarios and the increasing nitrate loads to coastal systems, coastal sediments may lose their capability to mitigate nitrogen pollution due to DNRA dominating over denitrification during extended hypoxic periods.

description: Light's wave-particle duality is at the heart of quantum mechanics and can be well illustrated by Wheeler's delayed-choice experiment. The choice of inserting or removing the second classical (quantum) beam splitter in a Mach-Zehnder interferometer determines the classical (quantum) wave-particle behaviors of a photon. In this paper, we report our experiment using the classical beam splitter to observe the simultaneous wave-particle behaviors in the wave-packet of a narrowband single photon. This observation suggests that it is necessary to generalize the current quantum wave-particle duality theory. Our experiment demonstrates that the produced wave-particle state can be considered an additional degree of freedom and can be utilized in encoding quantum information.

description: We study the interplay between network topology and complex space-time patterns and introduce a concept to analytically predict complex patterns in networks of Stuart-Landau oscillators with linear symmetric and instantaneous coupling based solely on the network topology. These patterns consist of partial amplitude death and partial synchronization and are found to exist in large variety for all undirected networks of up to 5 nodes. The underlying concept is proved to be robust with respect to frequency mismatch and can also be extended to larger networks. In addition it directly links the stability of complete in-phase synchronization to only a small subset of topological eigenvalues of a network.

description: Drawing on historical and contemporary examples from different European countries, this paper explores the diverse landscape of training and professionalisation in the arts therapies. As such different approaches and pathways of development are outlined alongside considerations of the socio- political conditions of different countries. After a brief historical note regarding the development of the arts therapies, we focus on training within modern European contexts and explore issues of collaboration and integration. Within this context, we discuss the role of professional bodies and reflect on the balance between shared standards and diversity in the arts therapies. This leads to a consideration of professional recognition and of its complexities.

description: В книге рассматриваются современные концепции информационного общества как научной системы взглядов, рассматривающей деятельность субъектов рынка с позиций присущих им знаний и процесса обмена информацией, то есть с позиций современной экономики знаний. В результате анализа экономической и институциональной составляющей среды деятельности субъектов рынка выявлена устойчивая тенденция на развитие института саморегулирования как формы институциональных взаимодействий субъектов рынка. Исследуется роль субъектов рынка в принципиальных границах неоинституциональной экономической теории как открытой «живой» системы на основе взаимосвязи трансформационных и трансакционных потоков, строящейся на принципах: связности; асимметрии информации; обучаемости индивидуальности системы знаний субъекта дана классификация взаимодействий субъектов рынка. В книге представлено теоретико-методологическое содержание институциональной матрицы с акцентом на ее трансакционной составляющей, уточнено содержание саморегулирования, обоснованы особенности саморегулирования субъектов рынка. На базе развития нового направления в экономической науке разработана комплексная методика оценки взаимодействия как саморегулируемой организации с заинтересованными группами в ее институциональной матрице, так и собственно между субъектами, в ней участвующими с позиций трансакционной составляющей деятельности.

description: Extra-solar planets direct imaging is now a reality with the deployment and commissioning of the first generation of specialized ground-based instruments (GPI, SPHERE, P1640 and SCExAO). These systems allow of planets $ 10 ^ 7 $ times fainter than their host star. For space-based missions (EXCEDE, EXO-C, EXO-S, WFIRST), various teams have demonstrated laboratory contrasts reaching $ 10 ^ { -10 } $ within a few diffraction limits from the star. However, all of these current and future systems are designed to detect faint planets around a single host star or unresolved multiples, while most non M-dwarf stars such as Alpha Centauri belong to multi-star systems. Direct imaging around binaries/multiple systems at a level of contrast allowing Earth-like planet detection is challenging because the region of interest is contaminated by the hosts star companion as well as the host Generally, the light leakage is caused by both diffraction and aberrations in the system. Moreover, the region of interest usually falls outside the correcting zone of the deformable mirror (DM) for the companion. Until now, it has been thought that removing the light of a companion star is too challenging, leading to the exclusion of binary systems from target lists of direct imaging coronographic missions. In this paper, we will show different new techniques for high-contrast imaging of planets around multi-star systems and detail the Super-Nyquist Wavefront Control (SNWC) method, which allows to control wavefront errors beyond nominal control region of the DM. Using the SNWC we reached contrasts around $ 5 \times 10 ^ { -9 } $ in a 10% bandwidth.

description: Shallow lakes can shift between stable states as a result of anthropogenic or natural drivers. Four common stable states differ in dominant groups of primary producers: submerged, floating, or emergent macrophytes or phytoplankton. Shifts in primary producer dominance affect key supporting, provisioning, regulating, and cultural ecosystem services supplied by lakes. However, links between states and services are often neglected or unknown in lake management, resulting in conflicts and additional costs. Here, we identify major shallow lake ecosystem services and their links to Sustainable Development Goals (SDGs), compare service provisioning among the four ecosystem states and discuss potential trade-offs. We identified 39 ecosystem services potentially provided by shallow lakes. Submerged macrophytes facilitate most of the supporting (86%) and cultural (63%) services, emergent macrophytes facilitate most regulating services (60%), and both emergent and floating macrophytes facilitate most provisioning services (63%). Phytoplankton dominance supports fewer ecosystem services, and contributes most to provisioning services (42%). The shallow lake ecosystem services we identified could be linked to 10 different SDGs, notably zero hunger (SDG 2), clean water and sanitation (SDG 6), sustainable cities and communities (SDG 11), and climate action (SDG13). We highlighted several trade-offs (1) among ecosystem services, (2) within ecosystem services, and (3) between ecosystem services across ecosystems. These trade-offs can have significant ecological and economic consequences that may be prevented by early identification in water quality management. In conclusion, common stable states in shallow lakes provide a different and diverse set of ecosystem services with numerous links to the majority of SDGs. Conserving and restoring ecosystem states should account for potential trade-offs between ecosystem services and preserving the natural value of shallow lakes.

description: Presented at CSCCE Open Source Tools Trial 1: https://www.cscce.org/2023/08/04/facilitating-community-activities-using-github-cscce-open-source-tools-trial-1/ In the first Tools Trial of this new series exploring open-source tools that support community building in STEM, we’re going to take a look at three use cases for how Github repositories can be used to facilitate community collaborations. Github is one of THE platforms for open-source software developers, a place where they share code, fix errors, and suggest new features. However, you don’t need to be an expert developer to reap some of Github’s benefits as a place to manage distributed collaborations “out in the open.” – and indeed many OS community managers have found ways of using the platform to meet their coordination needs, and meet their members where they’re already working. In this Trial, we’ll start with a short intro to Github in case you’re new to the platform. Then, we’ll hear how three different communities, Data Umbrella, The Turing Way, and rOpenSci, are connecting and collaborating in Github to create a community-sourced blog, organize community events, and plan engaging community calls, respectively. There will be plenty of time for Q&A and discussion, so come prepared to engage with our speakers!

description: A growth accounting analysis of the Korean agricultural sector is carried out using time series data for the period 1970-2010. The results show that the average growth rate of Korean agricultural sector during the period is 2.24%, to which total factor productivity contributes 1.86%p and capital stocks contribute 2.13%p while labor and land contribute -1.41%p and -0.36%p respectively. Additional analyses show that sharp successive drops in the growth rate of agricultural GDP during the 1990s and 2000s are mainly attributed to sharp declines of total factor productivity during the same period. This implies that policies for encouraging agricultural growth should be targeted at raising incentives for investment in R&D and human capital formation, which help enhance agricultural productivity.
Confidence Intervals for the Treatment Effects in Adaptive Enrichment Designs

description: While safety is the primary objective in Phase I designs of pharmacological or novel treatment development clinical trials, the focus shifts to detecting the effectiveness of the experimental treatment in confirmatory seamless Phase II/III designs. The presence of patient heterogeneity in modern medication development is widely acknowledged. The response of patients to the same treatment might vary depending on factors such as their gender, age, lifestyle, or genetic diversity. Therefore, it is necessary to determine which group of the population is more likely to benefit from the experimental treatment in the Phase II/III designs. In order to save time and cost, the adaptive enrichment design was proposed. The adaptive enrichment design concentrates resources on promising subgroups by allowing modifications based on the interim analysis results. However, the adaptive nature of the procedure complicates the estimation of the treatment effects and makes the quantification of uncertainty in treatment effects challenging. In particular, confidence intervals based on the naive maximum likelihood estimate and corresponding Fisher information will tend to have incorrect coverage. Focusing on a two-stage design with two disjoint subgroups, we develop a general method based on devising an appropriate p-value function. We derive the conditional confidence intervals for selected subgroups by inverting their corresponding conditional p-value functions, which are obtained using stage-wise, score, and MLE sample space orderings methods. Comparing the confidence intervals produced from the aforementioned space ordering methods reveals that score ordering treats each stage more evenly. Additionally, we construct the unconditional p-value function for each subgroup and utilize the classic Bonferroni, Bonferroni-Holm, and parameter-dependent weighted Bonferroni multiple testing procedures to create simultaneous confidence intervals at the end of the trial. We demonstrate that BonferroniHolm is most effective at detecting actual treatment effects, but its confidence interval for rejected hypotheses is uninformative when not all hypotheses are rejected. In contrast, the traditional Bonferroni simultaneous confidence intervals provide information regarding the magnitude of the real treatment effect but are less effective at rejecting false null hypotheses. The weighted parameter-dependent Bonferroni method compromises between informativeness and power. The confidence interval construction approach is illustrated through the application of two adaptive enrichment designs. Simulation studies show that our approach constructs confidence intervals with exact asymptotic coverage probabilities. Our method may be extended to k-stage msubgroup adaptive enrichment design with k ≥ 3 and m ≥ 3; although, the computation cost will also increase.

description: Climate warming in combination with nutrient enrichment can greatly promote phytoplankton proliferation and blooms in eutrophic waters. Lake Taihu, China, is a large, shallow and eutrophic system. Since 2007, this lake has experienced extensive nutrient input reductions aimed at controlling cyanobacterial blooms. However, intense cyanobacterial blooms have persisted through 2017 with a record-setting bloom occurring in May 2017. Causal analysis suggested that this bloom was sygenerically driven by high external loading from flooding in 2016 in the Taihu catchment and a notable warmer winter during 2016/2017. High precipitation during 2016 was associated with a strong 2015/2016 El Niño in combination with the joint effects of Atlantic Multi-decadal Oscillation (AMO) and Pacific Decadal Oscillation (PDO), while persistent warmth during 2016/2017 was strongly related to warm phases of AMO and PDO. The 2017 blooms elevated water column pH and led to dissolved oxygen depletion near the sediment, both of which mobilized phosphorus from the sediment to overlying water, further promoting cyanobacterial blooms. Our finding indicates that regional climate anomalies exacerbated eutrophication via a positive feedback mechanism, by intensifying internal nutrient cycling and aggravating cyanobacterial blooms. In light of global expansion of eutrophication and blooms, especially in large, shallow and eutrophic lakes, these regional effects of climate anomalies are nested within larger scale global warming predicted to continue in the foreseeable future.

description: The scientific consensus on climate change is strong, and evidence points
      to the need to take action to drastically reduce emissions of greenhouses
      gases. At the Paris summit in 2015, 195 world leaders set a clear goal to
      limit climate change. Yet the means to achieve this goal remain firmly at
      the level of the nation-state, with each country assuming responsibility
      for its own national plan. Thus national administrations, run by elected
      politicians, have a crucial role to play. It is the role of politicians to
      put in place the strategies, policies and incentives necessary to
      facilitate emissions reductions. How does this commitment at the level of
      the nation-state fit with a politician’s mandate as a democratically
      elected representative? What role do national politicians think they can
      and should play in responding to climate change?

      The study explores these questions empirically, seeking to understand how
      Members of the UK Parliament (MPs) understand climate change and its
      implications for political and social life, and their deliberations about
      whether or how to act on the issue. The work is informed by an
      interdisciplinary literature including science and technology studies,
      sociology, political science and environmental governance. It uses a mixed
      method approach, comprising corpus analysis of political speech, a focus
      group with climate advocates, and two sets of qualitative interviews with
      MPs.

      The study finds that, whilst politicians understand, to varying degrees,
      the need for action on climate change, it is not straightforward for them
      to make a case for action. There are three main reasons for this. First,
      the literal and metaphorical scale of climate change in comparison to the
      procedures and preoccupations of daily politics. Second, politicians
      consider the climate issue in the context of their professional identity
      and the cultural norms of their workplace, and report that climate action
      does not ‘fit’ with these norms. Third, UK politicians feel very little
      pressure from their electors to act on climate change, and have to work to
      build a democratic case for climate action.

      The study offers recommendations for both research and practice. In terms
      of research, there is a need for a more fine-grained, contextual
      understanding of the interplay between global goals and national political
      systems. In terms of practice, politicians, working with other
      stakeholders, need support in order to articulate the scale and
      significance of the climate challenge, and craft responses which build
      democratic support for further action.
