Leachate and contact test with Lepidium sativum L. to assess the phytotoxicity of waste
Authors: Bożym M. , Król A. , Mizerna K. 
Published: October 2020

AbstractThe study evaluated the use of Lepidium sativum L. to assess the phytotoxicity of three types of waste such as hazardous waste (slags from zinc to copper smelters) and nonhazardous waste (mineral–organic composite). Previous studies evaluated heavy metal leaching and the environmental impact of the tested waste. The purpose of phytotoxicity studies was to increase knowledge about this waste. Two types of tests were used to assess the phytotoxicity of wastes: germination index and accumulation test. Both tests were carried out for leachate (leachate test) and waste (contact test). The results of both tests were compared to assess the phytotoxic effects of tested waste. Phytotoxicity tests have shown that the mineral–organic composite leachate was stimulated plant growth, copper smelter slag leachate was characterized by no phytotoxicity and zinc slag leachate inhibited the growth of plants. In contrast, contact test showed inhibitory effects from all tested waste. Wherefore, the contact test was indicated as more sensitive in the assessment of phytotoxicity. However, this is not a clear assessment, because the germination index values for both tests were a result of differences of root length for both control samples (deionized water and sand). The study confirmed the usefulness of L. sativum for the assessment of phytotoxicity of various types of waste. Additionally, it was found that L. sativum was resistant to high concentrations of heavy metals in the leachate, without causing any negative physiological effects.

Authors: Niemann Jan-Uwe , Menssen Max , Poehling Hans-Michael 
Published: October 2020

AbstractWhiteflies are major pests on several vegetable and ornamental crops. Landing behaviour is strongly influenced by wavelength (nm) of reflected light from ground and surrounding vegetation. This paper deals with manipulation of whitefly landing behaviour in semi-field greenhouse experiments using background foils, either white foils with high reflection of short wavelength radiation or green foils reducing contrast between target plants and background (soil). The reactions of two different whitefly species were compared to detect possible differences between specialist (Aleyrodes proletella) and generalist (Trialeurodes vaporariorum) species. Dual-choice experiments were performed in a greenhouse using ice-lettuce,Lactuca sativavar. capitata (T. vaporariorum) and broccoli,brassica oleraceravar. Italica P (A. proletella) as model plants. The results show strong impact of the white reflective foil in controlling landing behaviour of both species, whereas the effect of the contrast-minimising foil was much lower. Light influence was stronger on generalist than on specialist species. Mechanisms behind these effects and opportunities for inclusion in an integrated pest management strategy are discussed.

Published: October 2020

AbstractSpent catalysts being considered hazardous wastes exhibit a high metal content in mobile forms. In addition, growing demand for circular economy policy applications requires proper utilization of these wastes. This study aimed at the assessment of vanadium leaching from spent desulfurization catalyst derived from sulfuric acid plant dump located nearby a copper smelter. Chemical and phase composition of the catalyst has been characterized. The extraction has been performed using chemical (0.1-M and 1-M citric acid) and biological (biotic solution with Acidithiobacillus thiooxidans) methods, using different experimental parameters (pulp density, particle size, leaching time) to observe V leaching behavior and kinetics. The results revealed that both citric acid and bacteria carried out the extraction process well. The optimal parameters for acid leaching were < 0.2-mm particle size and 2% pulp density, which allowed to leach out 95% of V from spent catalyst within 48 h. The bacterially mediated extraction resulted in 93% V leached out within 21 days with 2% pulp density. The experiments showed that V present in the catalyst is susceptible to bioleaching and organic acid leaching with the latter being a quicker process.
Demonstrating the effectiveness of a residential education programme for disengaged young people: a preliminary report
Authors: Mastronardi Paul , Ainsworth Frank , Huefner Jonathan C. 
Published: October 2020

AbstractThis article reports on the early results of using behavioural and educational data to evaluate a residential education programme. The programme serves male and female students between 12 and 16 years of age who have been suspended or expelled from school due to behavioural issues or who refused to attend school. Using measures of behavioural and educational progress during care and reporting these changes over time provided empirical evidence that the programme was achieving its primary aims of ‘behaviour change and educational gains.’ Collecting and reporting this data has empowered the programme to increase programme effectiveness through both data-informed decision-making and ongoing programme evaluation.
From industry-wide parameters to aircraft-centric on-flight inference: Improving aeronautics performance prediction with machine learning
Authors: Dewez Florent , Guedj Benjamin , Vandewalle Vincent 
Published: October 2020

Abstract
Aircraft performance models play a key role in airline operations, especially in planning a fuel-efficient flight. In practice, manufacturers provide guidelines which are slightly modified throughout the aircraft life cycle via the tuning of a single factor, enabling better fuel predictions. However, this has limitations, in particular, they do not reflect the evolution of each feature impacting the aircraft performance. Our goal here is to overcome this limitation. The key contribution of the present article is to foster the use of machine learning to leverage the massive amounts of data continuously recorded during flights performed by an aircraft and provide models reflecting its actual and individual performance. We illustrate our approach by focusing on the estimation of the drag and lift coefficients from recorded flight data. As these coefficients are not directly recorded, we resort to aerodynamics approximations. As a safety check, we provide bounds to assess the accuracy of both the aerodynamics approximation and the statistical performance of our approach. We provide numerical results on a collection of machine learning algorithms. We report excellent accuracy on real-life data and exhibit empirical evidence to support our modeling, in coherence with aerodynamics principles.
Law and Society Studies in Context: Suggestions for a Cross-Country Comparison of Socio-Legal Research and Teaching
Authors: Herklotz Tanja 
Published: October 2020

AbstractCultures of legal and socio-legal scholarship, like legal cultures themselves, are shaped by their respective historical, cultural, economic, and socio-political context. Socio-legal—or law and society—studies are thus pursued and taught differently in different parts of the world. This Article suggests making socio-legal studies the object of comparative research, so as to understand and explain commonalities, differences, and context dependencies in socio-legal scholarship and teaching in different countries. Such comparative endeavors help to translate between different academic languages and to critically reflect upon one’s own research methods and system of legal education. They prove useful for scholars planning research in other parts of the world or engaging in cross-country collaborative research projects, and for research institutions and policymakers involved in reforming research funding and legal education. But how do we go about comparing socio-legal studies? More specifically, why, what, and how do we compare, and what are the challenges that we may face when pursuing such comparative endeavors? This Article gives an overview of potential research questions that a comparison between socio-legal studies may address, the sources that comparativists may draw on, the methods such a comparative endeavor may use to collect and analyze data, and the challenges researchers may face when attempting to compare socio-legal studies in different parts of the world.
The Comparative Sociology of Legal Doctrine: Thoughts on a Research Program
Authors: Boulanger Christian 
Published: October 2020

AbstractIn the context of the encounter of UK and German socio-legal studies in this issue, this Article develops preliminary thoughts on a research agenda for the comparative interdisciplinary empirical study of legal doctrine. Based on a working definition of doctrine as an institutionally legitimized practice of making statements on the law, it presents an overview of sociological and comparative theorizing about doctrine in Germany, and of the data and methods being used to study it, in order to identify similar or diverging trends in the UK and elsewhere. This Article aims to show that legal doctrine, which is often regarded by non-lawyers as arcane and/or tedious, is an interesting and important subject for comparative socio-legal research.
Researching Urban Law
Authors: Layard Antonia 
Published: October 2020

AbstractThis Article considers the development of urban law. It suggests that urban law is socio-legal in its exploration of law’s role in the production of the city and urban life, enabling the study of the city as a distinctive legal entity. Addressing the question “why urban law?,” this Article considers similar debates in geography and urban policy before developing three arguments for studying urban law: (i) urbanism is a vibrant field of scholarly research; (ii) socio-legal research can take an explicitly normative focus in pursuit of improving urban quality; and (iii) at a city scale we can investigate governance concepts of territory, sovereignty and jurisdiction. One of the difficulties with urban law is finding the right level of analysis, covering sufficient legal and empirical detail whilst also making the city legible at an urban scale. Although this tension produces imperfect compromises, accepting the limitations means that we can begin the shared task of developing an intellectual infrastructure, a grammar, for the study of urban law.

AbstractBackgroundThere is evidence that environmental and genetic risk factors for schizophrenia spectrum disorders are transdiagnostic and mediated in part through a generic pathway of affective dysregulation.MethodsWe analysed to what degree the impact of schizophrenia polygenic risk (PRS-SZ) and childhood adversity (CA) on psychosis outcomes was contingent on co-presence of affective dysregulation, defined as significant depressive symptoms, in (i) NEMESIS-2 (n = 6646), a representative general population sample, interviewed four times over nine years and (ii) EUGEI (n = 4068) a sample of patients with schizophrenia spectrum disorder, the siblings of these patients and controls.ResultsThe impact of PRS-SZ on psychosis showed significant dependence on co-presence of affective dysregulation in NEMESIS-2 [relative excess risk due to interaction (RERI): 1.01, p = 0.037] and in EUGEI (RERI = 3.39, p = 0.048). This was particularly evident for delusional ideation (NEMESIS-2: RERI = 1.74, p = 0.003; EUGEI: RERI = 4.16, p = 0.019) and not for hallucinatory experiences (NEMESIS-2: RERI = 0.65, p = 0.284; EUGEI: −0.37, p = 0.547). A similar and stronger pattern of results was evident for CA (RERI delusions and hallucinations: NEMESIS-2: 3.02, p < 0.001; EUGEI: 6.44, p < 0.001; RERI delusional ideation: NEMESIS-2: 3.79, p < 0.001; EUGEI: 5.43, p = 0.001; RERI hallucinatory experiences: NEMESIS-2: 2.46, p < 0.001; EUGEI: 0.54, p = 0.465).ConclusionsThe results, and internal replication, suggest that the effects of known genetic and non-genetic risk factors for psychosis are mediated in part through an affective pathway, from which early states of delusional meaning may arise.
Good intentions and bad consequences: The general assistance mandate of the Trust Fund for Victims of the ICC
Authors: Rauxloh Regina E. 
Published: October 2020

AbstractRecognizing the needs of victims in international criminal justice, the International Criminal Court (ICC or the Court) has introduced an innovative reparation scheme including the establishment of the Trust Fund for Victims. Besides the Fund’s role to implement reparation orders, a second mandate has been developed to provide immediate help to victims independent from a criminal conviction: the general assistance mandate. Surprisingly, this mandate has to date attracted little attention from scholars and remains vastly under-researched. By exploring in detail the work of the general assistance mandate, this article exposes its structural weaknesses as well as the negative impact it has on the procedures of the Court as a whole. It will demonstrate how the general assistance mandate weakens the legitimacy of the ICC as it undermines the presumption of innocence, risks compromising international and national Court proceedings, and masks the weaknesses of the Court. While there is no doubt that humanitarian assistance is urgently needed in situations that are investigated by the ICC, the mechanism chosen, namely the Trust Fund’s general assistance mandate is not an adequate solution. This article argues that general assistance has no place in an international criminal court and should, therefore, be completely separated from the ICC.

Published: October 2020

AbstractEffects of stresses associated with extremely preterm birth may be biologically “recorded” in the genomes of individuals born preterm via changes in DNA methylation (DNAm) patterns. Genome-wide DNAm profiles were examined in buccal epithelial cells from 45 adults born at extremely low birth weight (ELBW; ≤1000 g) in the oldest known cohort of prospectively followed ELBW survivors (Mage = 32.35 years, 17 male), and 47 normal birth weight (NBW; ≥2500 g) control adults (Mage = 32.43 years, 20 male). Sex differences in DNAm profiles were found in both birth weight groups, but they were greatly enhanced in the ELBW group (77,895 loci) versus the NBW group (3,424 loci), suggesting synergistic effects of extreme prenatal adversity and sex on adult DNAm profiles. In men, DNAm profiles differed by birth weight group at 1,354 loci on 694 unique genes. Only two loci on two genes distinguished between ELBW and NBW women. Gene ontology (GO) and network analyses indicated that loci differentiating between ELBW and NBW men were abundant in genes within biological pathways related to neuronal development, synaptic transportation, metabolic regulation, and cellular regulation. Findings suggest increased sensitivity of males to long-term epigenetic effects of extremely preterm birth. Group differences are discussed in relation to particular gene functions.
Generalist genes and specialist environments for adolescent internalizing and externalizing problems: A test of severity and directionality
Authors: Marceau Kristine , Neiderhiser Jenae 
Published: October 2020

AbstractThe generalist genes specialist environment model, when applied to developmental psychopathology, predicts that genetic influences should explain variance that is shared across internalizing and externalizing problems, whereas environmental influences should explain variance that distinguishes the two overarching problem types. The present study is a direct test of this hypothesis, leveraging a sample of 708 twins and siblings (aged 10–18 years, 93% White) from the United States. Measures of severity of symptoms, regardless of type, and of directionality of symptoms – whether the adolescent tended to exhibit more externalizing or internalizing problems – were subjected to genetic (A), shared environmental (C), and nonshared environmental (E) (ACE) variance decompositions. As expected, severity of problems was under substantial genetic influence, but there were also significant shared and nonshared environmental influences. Contrary to the generalist genes specialist environment model, directionality of problem type was also under considerable genetic influence, with modest nonshared environmental influence. Findings corroborate existing evidence from other designs highlighting the role of familial influences (including generalist genes) in comorbidity of adolescent internalizing and externalizing problems, but suggest that the specialist environments hypothesis may not be the key factor in distinguishing problem type.
Frozen (Δ + 1)-colourings of bounded degree graphs
Authors: Bonamy Marthe , Bousquet Nicolas , Perarnau Guillem 
Published: October 2020

AbstractLet G be a graph on n vertices and with maximum degree Δ, and let k be an integer. The k-recolouring graph of G is the graph whose vertices are k-colourings of G and where two k-colourings are adjacent if they differ at exactly one vertex. It is well known that the k-recolouring graph is connected for
$k\geq \Delta+2$
. Feghali, Johnson and Paulusma (J. Graph Theory83 (2016) 340–358) showed that the (Δ + 1)-recolouring graph is composed by a unique connected component of size at least 2 and (possibly many) isolated vertices.In this paper, we study the proportion of isolated vertices (also called frozen colourings) in the (Δ + 1)-recolouring graph. Our first contribution is to show that if G is connected, the proportion of frozen colourings of G is exponentially smaller in n than the total number of colourings. This motivates the use of the Glauber dynamics to approximate the number of (Δ + 1)-colourings of a graph. In contrast to the conjectured mixing time of O(nlog n) for
$k\geq \Delta+2$
colours, we show that the mixing time of the Glauber dynamics for (Δ + 1)-colourings restricted to non-frozen colourings can be Ω(n2). Finally, we prove some results about the existence of graphs with large girth and frozen colourings, and study frozen colourings in random regular graphs.
Maximal versus sub-maximal effort during cardiopulmonary exercise testing in adults with congenital heart disease: outcome analysis of short-term cardiac-related events

Published: October 2020

AbstractPeak respiratory exchange ratio is an objective marker of patient effort during cardiopulmonary exercise testing. We evaluated exercise variables in 175 adult congenital heart disease patients and the impact of respiratory exchange ratio on the prognostic value of exercise variables for short-term cardiac-related events. Of 175 patients, 110 completed the exercise test with a peak respiratory exchange ratio of ≥1.10 and the remaining 65 had a peak respiratory exchange ratio of <1.10. Peak oxygen consumption, the percentage of oxygen consumption at the ventilatory threshold, peak heart rate, percentage predicted peak heart rate, double product, oxygen uptake efficiency slope, and the number of patients with exercise oscillatory ventilation were reduced significantly in patients with a respiratory exchange ratio of <1.10 compared to those with a respiratory exchange ratio of ≥1.10. After a median follow-up of 21 months, total cardiac-related events occurred in 37 (21%) patients. Multivariate Cox proportional hazard analysis showed that the percentage predicted peak oxygen consumption, and oxygen uptake efficiency slope were independent predictors of cardiac-related events only in patients with a peak respiratory exchange ratio of ≥1.10. Sub-maximal exercise performance can be preserved in adult congenital heart disease patients. The percentage predicted oxygen consumption and the oxygen uptake efficiency slope are two independent predictors for short-term cardiac-related events in adult congenital heart disease patients.

AbstractObjective:To determine the association between food insecurity and HIV infection with depression and anxiety among new tuberculosis (TB) patients.Design:Our cross-sectional study assessed depression, anxiety and food insecurity with Patient Health Questionnaire (PHQ-9), Zung Anxiety Self-Assessment Scale (ZUNG) and Household Food Insecurity Access Scale, respectively. Poisson regression models with robust variance were used to examine correlates of depression (PHQ-9 ≥ 10) and anxiety (ZUNG ≥ 36).Setting:Gaborone, Botswana.Participants:Patients who were newly diagnosed with TB.Results:Between January and December 2019, we enrolled 180 TB patients from primary health clinics in Botswana. Overall, 99 (55·0 %) were HIV positive, 47 (26·1 %), 85 (47·2 %) and 69 (38·5 %) indicated depression, anxiety and moderate to severe food insecurity, respectively. After adjusting for potential confounders, food insecurity was associated with a higher prevalence of depression (adjusted prevalence ratio (aPR) = 2·30; 95 % CI 1·40, 3·78) and anxiety (aPR = 1·41; 95 % CI 1·05, 1·91). Prevalence of depression and anxiety was similar between HIV-infected and HIV-uninfected participants. Estimates remained comparable when restricted to HIV-infected participants.Conclusions:Mental disorders may be affected by food insecurity among new TB patients, regardless of HIV status.
Low Melting Temperature of Anhydrous Mantle Materials at the Core‐Mantle Boundary

Published: October 2020

AbstractOne of the central challenges in accurately estimating the mantle melting temperature is the sensitivity of the probe for detecting a small amount of melt at the solidus. To address this, we used a multichannel collimator to enhance the diffuse X‐ray scattering from a small amount of melt and probed an eutectic pyrolitic composition to increase the amount of melt at the solidus. Our in situ detection of diffuse scattering from the pyrolitic melt determined an anhydrous melting temperature of 3,302 ± 100 K at 119 ± 6 GPa and 3,430 ± 130 K at the core‐mantle boundary (CMB) conditions, as the upper bound temperature. Our CMB temperature is approximately 700 K lower than the previous estimates, implying much faster secular cooling and higher concentrations of S, C, O, and/or H in the region, and nonlinear, advocating the basal magma ocean hypothesis.
