Modeling flexible generator operating regions via chance-constrained stochastic unit commitment
Authors: Singh Bismark , Knueven Bernard , Watson Jean-Paul 
Published: July 2020

AbstractWe introduce a novel chance-constrained stochastic unit commitment model to address uncertainty in renewables’ production in operations of power systems. For most thermal generators, underlying technical constraints that are universally treated as “hard” by deterministic unit commitment models are in fact based on engineering judgments, such that system operators can periodically request operation outside these limits in non-nominal situations, e.g., to ensure reliability. We incorporate this practical consideration into a chance-constrained stochastic unit commitment model, specifically by infrequently allowing minor deviations from the minimum and maximum thermal generator power output levels. We demonstrate that an extensive form of our model is computationally tractable for medium-sized power systems given modest numbers of scenarios for renewables’ production. We show that the model is able to potentially save significant annual production costs by allowing infrequent and controlled violation of the traditionally hard bounds imposed on thermal generator production limits. Finally, we conduct a sensitivity analysis of optimal solutions to our model under two restricted regimes and observe similar qualitative results.
Corpus Linguistics Methods in the Study of (Meta)Argumentation
Authors: Hinton Martin 
Published: July 2020

AbstractAs more and more sophisticated software is created to allow the mining of arguments from natural language texts, this paper sets out to examine the suitability of the well-established and readily available methods of corpus linguistics to the study of argumentation. After brief introductions to corpus linguistics and the concept of meta-argument, I describe three pilot-studies into the use of the terms Straw man, Ad hominem, and Slippery slope, made using the open access News on the Web corpus. The presence of each of these phrases on internet news sites was investigated and assessed for correspondence to the norms of use by argumentation theorists. All three pilot-studies revealed interesting facts about the usage of the terms by non-specialists, and led to numerous examples of the types of arguments mentioned. This suggests such corpora may be of use in two different ways: firstly, the wider project of improving public debate and educating the populace in the skills of critical thinking can only be helped by a better understanding of the current state of knowledge of the technical terms and concepts of argumentation. Secondly, theorists could obtain a more accurate picture of how arguments are used, by whom, and to what reception, allowing claims on such matters to be evidence, rather than intuition, based.

Published: July 2020

AbstractGeogenic arsenic contamination in groundwaters poses a severe health risk to hundreds of millions of people globally. Notwithstanding the particular risks to exposed populations in the Indian sub-continent, at the time of writing, there was a paucity of geostatistically based models of the spatial distribution of groundwater hazard in India. In this study, we used logistic regression models of secondary groundwater arsenic data with research-informed secondary soil, climate and topographic variables as principal predictors generate hazard and risk maps of groundwater arsenic at a resolution of 1 km across Gujarat State. By combining models based on different arsenic concentrations, we have generated a pseudo-contour map of groundwater arsenic concentrations, which indicates greater arsenic hazard (> 10 μg/L) in the northwest, northeast and south-east parts of Kachchh District as well as northwest and southwest Banas Kantha District. The total number of people living in areas in Gujarat with groundwater arsenic concentration exceeding 10 μg/L is estimated to be around 122,000, of which we estimate approximately 49,000 people consume groundwater exceeding 10 µg/L. Using simple previously published dose–response relationships, this is estimated to have given rise to 700 (prevalence) cases of skin cancer and around 10 cases of premature avoidable mortality/annum from internal (lung, liver, bladder) cancers—that latter value is on the order of just 0.001% of internal cancers in Gujarat, reflecting the relative low groundwater arsenic hazard in Gujarat State.
Examining how technology is presented and understood in technology education: a pilot study in a preschool class
Authors: Johansson Annie-Maj 
Published: July 2020

AbstractThe aim of the research is to examine how technology is communicated in technology education in relation to humans, society and nature in preschool class. According to the Swedish curriculum for preschool class, pupils should be given the opportunity to explore, ask questions and discuss technology and how the choices of people affect sustainable development. Teachers make different choices about, for example, content and what they do and do not say. These choices have an impact on how pupils perceive technology as part of the world and are called companion meanings. In terms of data, sound recordings and field notes from four technology lessons in a preschool class were used. The data was analysed, with focus on what types of companion meanings emerge in conversations between teachers and pupils. The analysis of companion meanings was based on two themes: Subject Language and Subject Focus. The results of this study demonstrate that pupils learn companion meanings of various types: for example, technology is something positive and unproblematic. Other types of companion meanings gave the pupils opportunities to reflect on how the technical choices of humans affect nature. Different kinds of companion meanings offer different ways for pupils to relate to the surrounding environment.
An Assessment of the Psychometric Properties of the GHQ-12 in an English Population of Autistic Adults Without Learning Difficulties

Published: July 2020

AbstractValid and reliable tools to measure mental health are a key requirement to developing a robust evidence base on mental health difficulties and autism. There are several reasons why mental health measures developed for the neurotypical population may not be valid and reliable when used with autistic adults. Using data collected from a national evaluation of community-based, specialist autism provision in England, this study assessed the psychometric properties of the General Health Questionnaire (GHQ-12) in a population of autistic adults without learning difficulties. We examined the measure’s acceptability, reliability and internal construct validity. The GHQ-12 was found to have good psychometric properties in this population. This provides first evidence that this measure can be used with autistic adults without LD.
Leibniz, Kant, and Referring in the Quantum Domain
Authors: Friebe Cord 
Published: July 2020

AbstractThe paper addresses the referring problem in quantum mechanics, by spelling out the alternatives with complete or individual concepts (Leibniz; in modern terms: definite descriptive proper names), with directly referential labels (standard formalism of quantum mechanics), and with intuition (Kant). The connection between the way of referring and some metaphysical theses about objects will be explained. Then, the paper intends to make plausible that the Kantian way is the best way for the quantum domain, including quantum field theories.
Artificial Intelligence and Medical Humanities
Authors: Ostherr Kirsten 
Published: July 2020

AbstractThe use of artificial intelligence in healthcare has led to debates about the role of human clinicians in the increasingly technological contexts of medicine. Some researchers have argued that AI will augment the capacities of physicians and increase their availability to provide empathy and other uniquely human forms of care to their patients. The human vulnerabilities experienced in the healthcare context raise the stakes of new technologies such as AI, and the human dimensions of AI in healthcare have particular significance for research in the humanities. This article explains four key areas of concern relating to AI and the role that medical/health humanities research can play in addressing them: definition and regulation of “medical” versus “health” data and apps; social determinants of health; narrative medicine; and technological mediation of care. Issues include data privacy and trust, flawed datasets and algorithmic bias, racial discrimination, and the rhetoric of humanism and disability. Through a discussion of potential humanities contributions to these emerging intersections with AI, this article will suggest future scholarly directions for the field.

Published: July 2020

AbstractPorous gold nanoparticles (PGNs) are very popular due to their high surface/volume ratio, moreover they have stronger plasmonic properties than their solid counterparts. These properties make the porous gold nanoparticles very useful for lots of applications, for instance chemical sensors, cancer therapy applications. For applications, however, it is indispensable that the resonance frequency (RF) of a plasmonic structure to be tuneable. In this work we show that the RF can be set in a wide range as desired by coating the PGNs by mixed oxide layers. By changing the composition of the coating layer, that is the mixture ratio, the RF can be shifted practically continuously in a wide range determined by the refractive index of the used oxides. As a demonstration, PGNs were coated with mixed alumina-titania oxide layers (5–7 nm) using plasma-enhanced atomic layer deposition method. The oxide layer, beside as a tuning tool, also stabilises the structure of the PGNs when are exposed to elevated temperature. This is shown by the influence of the temperature (from $$350\, ^{\circ }\hbox {C}$$

What, when and where of petitions submitted to the UK government during a time of chaos
Authors: Vidgen Bertie , Yasseri Taha 
Published: July 2020

AbstractIn times marked by political turbulence and uncertainty, as well as increasing divisiveness and hyperpartisanship, Governments need to use every tool at their disposal to understand and respond to the concerns of their citizens. We study issues raised by the UK public to the Government during 2015–2017 (surrounding the UK EU membership referendum), mining public opinion from a data set of 10,950 petitions, which contain 30.5 million signatures. We extract the main issues with a ground-up natural language processing method, latent Dirichlet allocation topic modelling. We then investigate their temporal dynamics and geographic features. We show that whilst the popularity of some issues is stable across the 2 years, others are highly influenced by external events, such as the referendum in June 2016. We also study the relationship between petitions’ issues and where their signatories are geographically located. We show that some issues receive support from across the whole country, but others are far more local. We then identify six distinct clusters of constituencies based on the issues which constituents sign. Finally, we validate our approach by comparing the petitions’ issues with the top issues reported in Ipsos MORI survey data. These results show the huge power of computationally analysing petitions to understand not only what issues citizens are concerned about but also when and from where.

Abstract
Aims
Root system responses to the limitation of either nitrogen (N) or phosphorus (P) are well documented, but how the early root system responds to (co-) limitation of one (N or P) or both in a stoichiometric framework is not well-known. In addition, how intraspecific competition alters plant responses to N:P stoichiometry is understudied. Therefore, we aimed to investigate the effects of N:P stoichiometry and competition on root system responses and overall plant performance.

Methods
Plants (Hordeum vulgare L.) were grown in rhizoboxes for 24 days in the presence or absence of competition (three vs. one plant per rhizobox), and fertilized with different combinations of N:P (low N + low P, low N + high P, high N + low P, and high N + high P).

Results
Shoot biomass was highest when both N and P were provided in high amounts. In competition, shoot biomass decreased on average by 22%. Total root biomass (per plant) was not affected by N:P stoichiometry and competition but differences were observed in specific root length and root biomass allocation across soil depths. Specific root length depended on the identity of limiting nutrient (N or P) and competition. Plants had higher proportion of root biomass in deeper soil layers under N limitation, while a greater proportion of root biomass was found at the top soil layers under P limitation.

Conclusions
With low N and P availability during early growth, higher investments in root system development can significantly trade off with aboveground productivity, and strong intraspecific competition can further strengthen such effects.
Clinical manifestations and management of fatty acid oxidation disorders
Authors: Merritt J. Lawrence , MacLeod Erin , Jurecka Agnieszka , Hainline Bryan 
Published: July 2020

AbstractFatty acid oxidation disorders (FAOD) are a group of rare, autosomal recessive, metabolic disorders caused by variants of the genes for the enzymes and proteins involved in the transport and metabolism of fatty acids in the mitochondria. Those affected by FAOD are unable to convert fatty acids into tricarboxylic acid cycle intermediates such as acetyl-coenzyme A, resulting in decreased adenosine triphosphate and glucose for use as energy in a variety of high-energy–requiring organ systems. Signs and symptoms may manifest in infants but often also appear in adolescents or adults during times of increased metabolic demand, such as fasting, physiologic stress, and prolonged exercise. Patients with FAOD present with a highly heterogeneous clinical spectrum. The most common clinical presentations include hypoketotic hypoglycemia, liver dysfunction, cardiomyopathy, rhabdomyolysis, and skeletal myopathy, as well as peripheral neuropathy and retinopathy in some subtypes. Despite efforts to detect FAOD through newborn screening and manage patients early, symptom onset can be sudden and serious, even resulting in death. Therefore, it is critical to identify quickly and accurately the key signs and symptoms of patients with FAOD to manage metabolic decompensations and prevent serious comorbidities.
Reflections of Legal Culture in Television Comedy: Social Critique and Schadenfreude in the US Series “Frasier”
Authors: Machura Stefan , Litvinova Olga 
Published: July 2020

AbstractTraces of law can be found in all aspects of life, law is ubiquitous. People relate law to some of their most desperate life situations, and sometimes law serves them well. It is no wonder that law features prominently in popular comedies. There also is a tradition to ridicule authorities and social institutions, and the law, courts and legal professionals are no exemption. In order to be understandable and “funny”, there needs to be at least a fleeting familiarity of the audience with them. Popular tv comedies thus offer a unique window into popular legal culture: they show elements of law and aspects of its workings, of the behaviour of lawyers, which the public relates to. For example, previous media coverage, other lawyer television and movies, or indeed personal experience, may have introduced them and something made this information stick, perhaps a rather objectionable practice. “Law” in this context has to be taken in its widest possible meaning as “living law” (Eugen Ehrlich), which means including those non-statutory rules by which society is organized, by which people live their daily lives. A further dimension which lends itself to good entertainment is rule-breaking behaviour, which often testifies for the validity of laws, only that they are inconvenient in certain situations. Again, a constellation that invites mockery, humour andSchadenfreude. The manuscript will apply a cultural and socio-legal perspective to the depiction of things legal in one of the most outstanding US television comedies, shown to audiences internationally: “Frasier” (1993–2004).

Published: July 2020

AbstractSocial media platforms have conquered almost all fields of human life; their impact as opinion creating tools is undisputable. They not only offer a place for people to exchange experiences, but are also a virtual space where people fight with words in defence of their beliefs. This second function has made social media a rich source for linguistic analysis, providing material for the most current social, political, and economic issues. The main aim of this paper is to contribute to reducing the identified gap in the literature on hate speech and consequential cyberbullying from the linguistic perspective and provide conclusions on elements of hate speech through the analysis of statements relating to the cut-out of the Białowieża National Forest. The examples were excerpted from the Polish social media websites of activists representing two opponent groups. This paper consists of three parts. The first part provides an overview of the literature related to hate speech, cyberbullying, their definitions, roles, and the possibilities of analysis. In this part, the background of the discussed polemic is also highlighted (the geographic location of the Białowieża National Forest, arguments used by both sides of the conflict etc.). The second part of the paper presents and discusses the results of the conducted research. After having examined some of the social media platforms used by the groups representing different attitudes to the described conflict (including Facebook, Twitter etc.), we have identified linguistic patterns within aggressive and vulgar statements expressed both directly and indirectly. Therefore, our analysis concentrates on categorisation of characteristic elements of hate statements. In the third part of the paper, we present conclusions referring to the results of the analysis.
Exploring the Relationship between Social Class and Quality of Life: the Mediating Role of Power and Status

Published: July 2020

AbstractWhy does social class affect Quality of Life? We simultaneously investigated two novel possible explanations: Because a high social class is associated with increased control over resources (i.e., power) or because a high social class is associated with higher respect and esteem in the eyes of others (i.e., status). To test these explanations, we collected data from 384 US-based individuals. We measured their social class, power, status, and four facets of Quality of Life (physical, mental, social, and environmental). For each facet, we calculated the correlation with social class. Next, we tested whether the relationship between social class and the specific facet was mediated by power, status, or both. Social class correlated significantly with all facets of Quality of Life (physical, mental, social, and environmental). Using parallel mediation models, we found that this positive relationship was mediated by status, but not by power. For some facets of Quality of Life (physical, environmental), power even had a negative indirect effect. These results suggest that upper-class individuals indeed have a higher Quality of Life. However, this seems to be mostly due to the increased status of upper-class individuals, whereas power was less important or even had detrimental effects on Quality of Life. Researchers and policymakers aiming to address class-based Quality of Life inequality could thus benefit from focusing on status as an important mediator. Moreover, our work demonstrates the importance of considering power and status as distinct constructs, in order to fully unravel the relationship between social class and Quality of Life.

AbstractTo assess the role of live porcine simulation in robotic surgical skills training. A qualitative and quantitative survey was conducted of participants of a live porcine robotic simulation course undertaken in a regional training centre. Data on participants’ experience, robotic surgical ability, the educational impact and outcomes from the course were collected. Thirty-nine participants from four different countries completed the survey. Clinical experience varied; however, prior robotic surgical experience (median 0 cases, range 0–100) and technical ability were low. The perceived usefulness, effectiveness and realism of the training course were all highly scored. Participants rated the most useful course components as port placement and docking, basic robotic skills training and repair of a bladder injury. Training resulted in significant increases in technical ability (p < 0.0001). Following the course, 49% of participants continued to either train or perform robotic surgery. This survey demonstrates that live porcine simulation for robotic surgery is a highly valued, acceptable and feasible form of training. The majority of participants were relatively inexperienced but nonetheless significant improvements in technical ability were reported. The results of this survey support the use of live porcine training for robotic surgery.
