Published: May 2020

AbstractIn situ high-frequency measured turbidity can potentially be used as a surrogate for riverine phosphorus (P) concentrations to better justify the effectiveness of nutrient loss mitigation measures at agricultural sites. We explore the possibilities of using turbidity as a surrogate for total phosphorus (TP) and particulate phosphorus (PP) in four snowmelt-driven rivers draining agricultural clayey catchments. Our results suggest slightly stronger relationship between in situ measured turbidity andPPthan between turbidity andTP. Overall, linearTPandPPregressions showed better error statistics in the larger catchments compared with their sub-catchments. Local calibration of the in situ sensors was sensitive to the number of high P concentration discrete water samples. Two optional calibration curves, one with and one without influential data, resulted in a 17% difference in the estimated meanTPconcentrations of a snowmelt storm contributing 18% of the annual discharge volume. Accordingly, the error related to monthly meanTPestimates was the largest in spring months at all sites. The addition of total dissolved phosphorus (TDP) improved the model performance, especially for sites where theTDP/TPratio is large and highly variable over time. We demonstrate how long-term discrete samples beyond sensor deployment can be utilized in the evaluation of the applicability range of the local calibration. We recommend analysing the validity of P concentration estimates, especially during high discharge episodes that contribute substantially to annual riverine nutrient fluxes, since the use of surrogates may introduce large differences into the P concentration estimates based on selected local calibration curves.
A Loophole of All ‘Loophole-Free’ Bell-Type Theorems
Authors: Czachor Marek 
Published: May 2020

AbstractBell’s theorem cannot be proved if complementary measurements have to be represented by random variables which cannot be added or multiplied. One such case occurs if their domains are not identical. The case more directly related to the Einstein–Rosen–Podolsky argument occurs if there exists an ‘element of reality’ but nevertheless addition of complementary results is impossible because they are represented by elements from different arithmetics. A naive mixing of arithmetics leads to contradictions at a much more elementary level than the Clauser–Horne–Shimony–Holt inequality.
Perching birds or scattered streams: a study of how trust affects civic engagement among university students in contemporary China
Authors: Liu Ye , Shen Wenqin 
Published: May 2020

AbstractThis article explores how trust affects the nature and characteristics of civic engagement among university students in contemporary China. We draw upon empirical evidence from in-depth individual interviews involving 68 students born between 1993 and 1999. Four different types of civic activities, including associational membership with the Chinese Communist Party as well as self-organised town-fellowship associations, volunteering and digital activism, are analysed in relation to bridging, bonding and/or obligatory relationships. Generalised trust amongst university students seems to be low, but they do exhibit unquestioned trust in the State. The organisations with which they associate either are top-down through the Communist Party, which is ideologically narrow and socially distant among the members, or promote geographical origin-based bonding rather than bridging relationships. Our findings add new depth to our understanding of the relationships between the dominant modalities of trust and the typical form of civic participation in Chinese universities. We also highlight the effects of increasing meritocratic competition and stress on performativity on the civic attitudes and behaviour of students. We argue that the hybrid of neoliberal individualism and Confucianism seems to be a perfect match to reconcile the absence of civic traditions and to validate civic consciousness among university youth.

Published: May 2020

AbstractAn increasing threat to local, native freshwater mussels (Unionida)—an ecologically important but globally alarmingly declining group—is the invasion by exotic bivalves. The Enemy Release Hypothesis predicts that introduced species should benefit from enemy-mediated competition because they are less likely to be harmed by natural enemies, such as parasites, than their native competitors. We investigated within-site differences in parasitism between sympatric native (tot. five spp.) and invasive (tot. three spp.) bivalves in eight northern European waterbodies, which harboured totally 15 parasite taxa. In paired comparisons using within-site averages, the mean number of parasite species in the native bivalves was 2.3 times higher, and the sum of parasite prevalences 2.4 times higher, than in the invasive bivalves. This may lead to enemy-mediated competitive release of invaders and contribute to the success of invasive freshwater bivalves, in general. However, while the invasive clam Corbicula fluminea was completely free from parasites, parasite parameters of the other invader, Sinanodonta woodiana, were relatively high, indicating that the role of parasites can be invader-specific and urges further research. Understanding the factors affecting success of freshwater bivalve invasions, such as parasitism, can aid invasion control and conservation of local, native (endangered) bivalves.
Silent Voices: Exploring Narratives of Women's Experiences of Health Care Professional Responses to Domestic Violence and Abuse
Authors: McGarry Julie , Hinsliff-Smith Kathryn 
Published: May 2020

AbstractThe impact of domestic violence and abuse (DVA) is far reaching not least in terms of both the immediate and longer term physical and mental wellbeing of those who have experienced abuse. DVA also exerts a considerable detrimental impact on the wider family including children. While professional perspectives of working with DVA survivors is increasingly well documented, there remains a paucity of accounts of encounters with healthcare services and/or healthcare professionals from survivors of DVA themselves. A central aim of this study was the exploration of women’s experiences of healthcare encounters told purely as personal narrative rather than framed in more traditional research terms. The focus of this paper therefore is unedited personal stories of encounters with healthcare professionals. The position of narrative as research method and the presentation of narratives in this particular instance are also considered.

AbstractAimsThis study tests whether different spectral regions of sunlight affect the microbial decomposer assemblage in surface leaf litter in a beech understorey over the first 6 months following leaf senescence.MethodsWe performed a litterbag experiment employing filters attenuating combinations of UV-B, UV-A, blue, and green light as well as the whole spectrum of sunlight. We measured changes in microbial biomass and community structure, litter mass loss and litter chemistry during the first 6 months of decomposition.ResultsFungal and total microbial biomass were highest in the treatment excluding UV radiation, blue and green light. Exclusion of UV-B radiation decreased the fungal:bacterial biomass ratio and litter nitrogen content. Bacterial biomass was lower in the dark treatment compared to treatments receiving at least part of the solar spectrum. Our filter treatments affected microbial functional structure from the beginning of the experiment, whereas mass loss was only significantly affected after 6 months of decomposition and no effect was found on litter carbon content.ConclusionsThis study proves that sunlight, in a spectrally dependent manner, affects both microbial functional structure and biomass in temperate deciduous forests early in the decomposition process, with bacteria tending to dominate in sunlight and fungi in dark conditions. We found sunlight to be important in the decomposition in temperate forest understoreys despite the low irradiance characterizing these environments. However, long-term studies are required to estimate the relative contribution of sunlight among factors affecting the eventual incorporation of decomposing leaf litter into forest soils.
Bringing the doctoral thesis by published papers to the Social Sciences and the Humanities: A quantitative easing? A small study of doctoral thesis submission rules and practice in two disciplines in the UK
Authors: Rigby John , Jones Barbara 
Published: May 2020

AbstractThis paper examines how an alternative to the traditional monograph form of the doctoral thesis is emerging that reflects a new approach to the valuation and designation of scientific outputs. This new approach, based on co-citation as underpinning principle for the measurement of knowledge structures, values knowledge and knowledge producers in increasinglyquantitativeterms. Such a change aligns with wider institutional market-based approaches that have been transforming higher education sectors world-wide. Under these influences, which prioritize quantification and tangibility of output, with quality equated with citation, the thesis, a keyinstitutionof the university, is now subject to pressures to transform and be constituted by a series of publishable papers, referred to by a variety of terms, the most common being ‘Thesis by Published Papers’, although ‘Journal Format Thesis’, ‘Alternative Format Thesis’, and ‘Integrated Thesis’ are also used. While the scientific disciplines have traditionally been closer to this paper-based model, albeit with significant national variations, Social Sciences and Humanities subjects are now being affected. We present evidence from a small study of the UK higher education sector of organisational regulations in 54 departments concerning doctoral degree submission formats in two disciplines in the Humanities and Social Sciences (History and Sociology). We investigate the prevalence of this new practice, investigate some of its key aspects, and identify a number of questions for future research on this emerging and important topic.
State of the art in the analysis of brominated flame retardants in biota and sediment: insights from the characterisation of two new certified reference materials
Authors: Ricci Marina , Shegunova Penka , Vorkamp Katrin 
Published: May 2020

AbstractThe Joint Research Centre (JRC) of the European Commission has recently released two new Certified Reference Materials (CRMs) for the analysis of brominated flame retardants (BFRs): the freshwater sediment ERM-CC537a and the fish tissue ERM-CE102. The production of these CRMs responds to the need of expanding the offer of quality assurance/quality control tools for the analysis of BFRs in the fields of environmental analysis and food control, especially for compliance purposes. The sediment ERM-CC537a carries certified values for polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCDD) diastereoisomers in the μg/kg range (dry mass), while the fish tissue ERM-CE102 is certified for PBDEs in the ng/kg range (wet weight). ERM-CC537a is the first reference material ever available with certified values for α-, β- and γ-HBCDD. The assignment of the certified values was performed via an intercomparison of expert laboratories. The evaluation of the data confirms the improving trend, observed in recent years, regarding the comparability of PBDE measurement results. The relative standard deviation (RSD) among laboratories is slightly better for the fish material (8–11%) compared to the sediment (9–15%), despite lower mass fractions in the biota matrix. The RSD of HBCDD data (17%) reveals that they are more challenging analytes. The average measurement uncertainty declared by the participants is about 30%, but an in-depth analysis of their performance reveals that it should be feasible to reduce the uncertainty budget.
Evaluation of the factors limiting biogas production in full-scale processes and increasing the biogas production efficiency
Authors: Kouzi Afamia I. , Puranen Matti , Kontro Merja H. 
Published: May 2020

AbstractBiogas production from sewage sludge volatile solids (VS) by anaerobic digestion slows down towards the end of the process, among inhibitory factors being pH increase upon ammonia accumulation, poorly digestible biomaterials, and high fixed solid (FS) content. The possibility of concentrating the digested sludge VS (41.7–56.6% on a dry weight basis) by surface and bottom layer separation with biogas post-production was studied. Furthermore, the potential to recycle concentrated VS and digested sludge back to the process after adjusting pH 7.0 to optimal for biogas-producing microbes and after acid, alkali, thermal, and sonolytic treatments was examined. In general, pH 7.0 control alone improved biogas production from the recycled digested sludge the most. An equally good improvement in biogas production was achieved by recycling the digested sludge, which had been heated until ammonia had evaporated and the pH dropped to 7.0 (1–2 h, 75 °C), and at the same time, VS was degraded. The biogas production from the sonicated and recycled sludge was almost as good as from the pH-adjusted, or heat-treated recycled sludge. After the acid and base treatments of the digested sludge, the recycled sludge yielded often the lowest biogas volume, as the added chemicals increased the FS concentration, which proved to be a more important inhibitory factor than poorly degradable VS. The high FS content significantly reduced the benefits of the treatments. By separating the surface and bottom layers with biogas post-production, the surface layer of VS was concentrated to 51.6–61.8%, while different compositions of the layers affected the biogas production.
Are the factors recommended by UNEP-SETAC for evaluating biodiversity in LCA achieving their promises: a case study of corrugated boxes produced in the US

Published: May 2020

Abstract
Purpose
We tested the effectiveness of the global and ecoregion-based average characterization factors (CFs) for “Potential Species Loss” recommended by the UNEP-SETAC Life Cycle Initiative to identify hotspots and improvement opportunities compared to using a land competition indicator for a product for which the predominant life cycle use of land is forest management.

Methods
For a case study of average corrugated boxes produced in the US, system boundaries were defined to encompass all life cycle stages from forest management to disposal. Fiber procurement was regionalized to US ecoregions, and (Chaudhary et al. Environ Sci Technol 49:9987–9995, 2015) ecoregion-specific CFs were applied. US-average CFs were applied to other background processes. Hotspots were identified using contribution analyses, and improvement opportunities were evaluated using scenarios. We compared the results with those from applying a land competition indicator, often used as a proxy for biodiversity in LCA.

Results and discussion
Forest management was identified as the activity within the life cycle of corrugated boxes that uses the greatest amount of land, allowing the definition of two potential improvement opportunities: reducing fiber consumption and intensifying forest management. By applying the recommended CFs, fiber procurement was also identified as the main contributor to “Potential Species Loss.” The CFs also allowed to identify ecoregions in which species were potentially the most affected by forest management and related potential improvement opportunities. Tradeoffs between taxonomic groups were discussed. In some cases, the results contradicted those from applying a land competition indicator, and in many cases, we were unable to reconcile the results obtained with existing scientific knowledge on species diversity and forest management.

Conclusions and recommendations
The results obtained by applying the recommended CFs could not always be reconciled with existing scientific knowledge on the effect of forest management on species diversity, significantly impairing the usefulness of these factors for assessing improvement opportunities and increasing the risk of counterproductive decisions. The local effect on species of forest management is likely to be misrepresented by the average number of species in a given ecoregion. Successful consideration of biodiversity response in the context of forest management would require the integration of other approaches, such as site-specific studies. Potential improvements to the proposed method include further spatialization of the CFs, defining a range of forest management practices for which CFs would be defined, considering forest productivity, and defining CFs using a baseline that would encourage better practices even within a given existing management regime.

Published: May 2020

AbstractThe novel coronavirus-2019 (COVID-19) pandemic has become globally widespread with millions of confirmed cases and many countries implementing various levels of quarantine. Therefore, it is important to investigate the psychological consequences of this process, given the unique situation that has been experienced globally. Therefore, the present study examined whether intolerance of uncertainty was related to mental wellbeing and whether this relationship was mediated by rumination and fear of COVID-19. The sample comprised 1772 Turkish individuals (aged between 18 and 73 years) from 79 of 81 cities in Turkey, who completed measures of mental wellbeing, intolerance of uncertainty, rumination, and fear of COVID-19. Results of serial mediation analyses showed that intolerance of uncertainty had a significant direct effect on mental wellbeing. Rumination and fear of COVID-19, in combination, serially mediated the association between intolerance of uncertainty and mental wellbeing. The findings are discussed within the framework of the psychological consequences of the COVID-19 pandemic and related literature.
Redox reactions of iron and manganese oxides in complex systems
Authors: Huang Jianzhi , Zhang Huichun 
Published: May 2020

AbstractConspectus: Redox reactions of Fe- and Mn-oxides play important roles in the fate and transformation of many contaminants in natural environments. Due to experimental and analytical challenges associated with complex environments, there has been a limited understanding of the reaction kinetics and mechanisms in actual environmental systems, and most of the studies so far have only focused on simple model systems. To bridge the gap between simple model systems and complex environmental systems, it is necessary to increase the complexity of model systems and examine both the involved interaction mechanisms and how the interactions affected contaminant transformation. In this Account, we primarily focused on (1) the oxidative reactivity of Mn- and Fe-oxides and (2) the reductive reactivity of Fe(II)/iron oxides in complex model systems toward contaminant degradation. The effects of common metal ions such as Mn2+, Ca2+, Ni2+, Cr3+ and Cu2+, ligands such as small anionic ligands and natural organic matter (NOM), and second metal oxides such as Al, Si and Ti oxides on the redox reactivity of the systems are briefly summarized.
Toxicity-oriented water quality engineering

Published: May 2020

AbstractThe fundamental goal of water quality engineering is to ensure water safety to humans and the environment. Traditional water quality engineering consists of monitoring, evaluation, and control of key water quality parameters. This approach provides some vital insights into water quality, however, most of these parameters do not account for pollutant mixtures - a reality that terminal water users face, nor do most of these parameters have a direct connection with the human health safety of waters. This puts the real health-specific effects of targeted water pollutant monitoring and engineering control in question. To focus our attention to one of the original goals of water quality engineering - human health and environmental protection, we advocate here the toxicity-oriented water quality monitoring and control. This article presents some of our efforts towards such goal. Specifically, complementary to traditional water quality parameters, we evaluated the water toxicity using high sensitivity toxicological endpoints, and subsequently investigated the performance of some of the water treatment strategies in modulating the water toxicity. Moreover, we implemented the toxicity concept into existing water treatment design theory to facilitate toxicity-oriented water quality control designs. Suggestions for the next steps are also discussed. We hope our work will intrigue water quality scientists and engineers to improve and embrace the mixture water pollutant and toxicological evaluation and engineering control.

AbstractEarly division of the dorsal pancreatic artery (DPA) or its branches to the uncinate process during pancreaticoduodenectomy (PD) in addition to early division of the gastroduodenal artery and inferior pancreaticoduodenal artery should be performed to reduce blood loss by completely avoiding venous congestion. However, the significance of early division of DPA or its branches to the uncinate process has not been reported. The aim of this study was to investigate the anatomy of DPA and its branches to the uncinate process using the currently available high-resolution dynamic computed tomography (CT) as the first step to investigate the significance of DPA in the artery-first approach during PD. Preoperative dynamic thin-slice CT data of 160 consecutive patients who underwent hepato–pancreato–biliary surgery were examined focusing on the anatomy of DPA and its branches to the uncinate process. DPA was recognized in 103 patients (64%); it originated from the celiac axis or its branches in 70 patients and from the superior mesenteric artery or its branches in 34 patients. The branches to the uncinate process were visualized in 82 patients (80% of those with DPA), with diameters of 0.5–1.5 mm in approximately 80% of the 82 patients irrespective of DPA origin. DPA branches to the uncinate process were recognized using high-resolution CT in approximately half of the patients.
