Investigating the role of swear words in abusive language detection tasks
Authors: Pamungkas Endang Wahyu , Basile Valerio , Patti Viviana 
Published: February 2022

AbstractSwearing plays an ubiquitous role in everyday conversations among humans, both in oral and textual communication, and occurs frequently in social media texts, typically featured by informal language and spontaneous writing. Such occurrences can be linked to an abusive context, when they contribute to the expression of hatred and to the abusive effect, causing harm and offense. However, swearing is multifaceted and is often used in casual contexts, also with positive social functions. In this study, we explore the phenomenon of swearing in Twitter conversations, by automatically predicting the abusiveness of a swear word in a tweet as the main investigation perspective. We developed the Twitter English corpus SWAD (Swear Words Abusiveness Dataset), where abusive swearing is manually annotated at the word level. Our collection consists of 2577 instances in total from two phases of manual annotation. We developed models to automatically predict abusive swearing, to provide an intrinsic evaluation of SWAD and confirm the robustness of the resource. We model this prediction task as three different tasks, namely sequence labeling, text classification, and target-based swear word abusiveness prediction. We experimentally found that our intention to model the task similarly to aspect-based sentiment analysis leads to promising results. Subsequently, we employ the classifier to improve the prediction of abusive language in several standard benchmarks. The results of our experiments show that additional abusiveness feature of the swear words is able to improve the performance of abusive language detection models in several benchmark datasets.
Promoting Less Complex and More Honest Price Negotiations in the Online Used Car Market with Authenticated Data

Published: February 2022

AbstractOnline peer-to-peer (P2P) sales of used and or high-value goods are gaining more and more relevance today. However, since potential buyers cannot physically examine the product quality during online sales, information asymmetries and consequently uncertainty and mistrust that already exist in offline sales are exacerbated in online markets. Authenticated data platforms have been proposed to solve these problems by providing authenticated data about the negotiation object, integrating it into text-based channels secured by IT. Yet, we know little about the dynamics of online negotiations today and the impact of the introduction of authenticated data on online negotiation behaviors. We address this research gap based on two experimental studies along with the example of online used car trade. We analyze users’ communicative and strategic actions in current P2P chat-based negotiations and examine how the introduction of authenticated data affects these behaviors using a conceptional model derived from literature. Our results show that authenticated data can promote less complex negotiation processes and more honest communication behavior between buyers and sellers. Further, the results indicate that chats with the availability of authenticated data can positively impact markets with information asymmetries. These insights provide valuable contributions for academics interested in the dynamics of online negotiations and the effects of authenticated data in text-based online negotiations. In addition, providers of trade platforms who aim to advance their P2P sales platforms benefit by achieving a competitive advantage and a higher number of customers.

AbstractIn this note we study the block spin mean-field Potts model, in which the spins are divided into s blocks and can take $$q\ge 2$$

different values (colors). Each block is allowed to contain a different proportion of vertices and behaves itself like a mean-field Ising/Potts model which also interacts with other blocks according to different temperatures. Of particular interest is the behavior of the magnetization, which counts the number of colors appearing in the distinct blocks. We prove central limit theorems for the magnetization in the generalized high-temperature regime and provide a moderate deviation principle for its fluctuations on lower scalings. More precisely, the magnetization concentrates around the uniform vector of all colors with an explicit, but singular, Gaussian distribution. In order to remove the singular component, we will also consider a rotated magnetization, which enables us to compare our results to various related models.

Published: February 2022

AbstractA method for rapid separation of americium from complex matrices by use of two commercially available extraction chromatography resins is reported. TRU resin is capable of purifying americium/lanthanides together from Group 1, Group 2 and transition metals. TRU resin tolerated high loadings of iron, aluminium, calcium sodium and potassium. TEVA resin purified americium/lanthanides by elution with ammonium thiocyanate. Decontamination factors > 20,000 were achieved within one working day. The affinity of TEVA resin for americium, curium and lanthanides as a function of ammonium thiocyanate concentration is reported. The possibility of americium/lanthanide separations on LN resin has been explored.

AbstractWe have developed a simple method to prepare nano-(ZrC0.93, ZrO2-polymorphs)@carbon composites with graphite/amorphous carbon content and adjustable Zr/C ratio based on using a multistep tube furnace and plasma-assisted heat treatment of zirconium-loaded sulfonated styrene–divinylbenzene (STY-DVB) copolymers. Pre-pyrolysis of zirconium-loaded sulfonated STY-DVB ion exchangers with 2 and 8 mass % DVB at temperatures between 1000 and 1400 °C for 2 h produced nano-ZrO2@C intermediates with particle sizes of ~ 30–60 nm with no ZrC formation. Plasma processing of nano-ZrO2@C resulted in nano-(ZrC0.93, ZrO2)@C composites with 11% (under a He atmosphere) (C/Zr = 73) or 13% (under a H2 atmosphere) (C/Zr = 58) ZrC0.93 content. Three polymorphs of the zirconium dioxide (tetragonal, monoclinic and cubic, between 18 and 27 nm) were found in the products. The amounts of tetragonal and monoclinic ones are comparable to that of ZrC0.93. The average particle size of ZrC0.93 prepared in this way was found to be 21–23 nm. The BET surface area of the nano-(ZrC0.93, ZrO2)@C(graphite) composites prepared in He and H2 was over 250 and 300 m2/g, respectively. We developed a reproducible and easy method to prepare nano-(ZrC, ZrO2)@C products by setting the DVB content, sulfonation degree, Zr loading and the thermal treatment conditions, which have an influence on the ZrC and graphite/amorphous carbon content of nano-ZrO2@C intermediates. The zirconium-loaded sulfonated styrene–divinylbenzene (STY-DVB) copolymers (2 and 8 mass% DVB) or their thermal decomposition was characterized with vibrational spectroscopy, thermal analysis and DSC or powder XRD, BET, XPS and HRTEM methods, respectively.
Paradoxes in the Management of Timebanks in the UK’s Voluntary Sector: Discursive Bricolage and its Limits

Published: February 2022

AbstractThis paper contributes to our understanding of volunteer management by charting some important challenges associated with the governance of one of the UK’s largest timebanking networks. While timebanking is often treated as a form of volunteering, many timebank advocates are keen to distinguish it sharply from traditional volunteering. We suggest that this tension generates a fundamental ‘performance paradox’ in the management of timebanks in the voluntary sector. We draw on political discourse theory to characterise and evaluate associated challenges, suggesting that, when viewed against a host of context-specific organisational and policy pressures, the progressive potential of timebanking cannot be realised as a distinct community economy without adequate support. Instead of taking up a position alongside more traditional forms of volunteering, timebanking is more likely to be subsumed by them.

AbstractParkinson’s disease (PD) is neurodegenerative disorder with the pathological hallmarks of progressive degeneration of midbrain dopaminergic neurons from the substantia nigra (SN), and accumulation and spread of inclusions of aggregated α-synuclein (α-Syn). Since current PD therapies do not prevent neurodegeneration, there is a need to identify therapeutic targets that can prevent α-Syn-induced reductions in neuronal survival and neurite growth. We hypothesised that genes that are normally co-expressed with the α-Syn gene (SNCA), and whose co-expression pattern is lost in PD, may be important for protecting against α-Syn-induced dopaminergic degeneration, since broken correlations can be used as an index of functional misregulation. Gene co-expression analysis of the human SN showed that nuclear zinc finger HIT-type containing 1 (ZNHIT1) is co-expressed with SNCA and that this co-expression pattern is lost in PD. Overexpression of ZNHIT1 was found to increase deposition of the H2A.Z histone variant in SH-SY5Y cells, to promote neurite growth and to prevent α-Syn-induced reductions in neurite growth and cell viability. Analysis of ZNHIT1 co-expressed genes showed significant enrichment in genes associated with mitochondrial function. In agreement, bioenergetic state analysis of mitochondrial function revealed that ZNHIT1 increased cellular ATP synthesis. Furthermore, α-Syn-induced impairments in basal respiration, maximal respiration and spare respiratory capacity were not seen in ZNHIT1-overexpressing cells. These data show that ZNHIT1 can protect against α-Syn-induced degeneration and mitochondrial dysfunction, which rationalises further investigation of ZNHIT1 as a therapeutic target for PD.

ZusammenfassungIm Rahmen einer Studie zum schriftlichen mathematischen Argumentieren wurde untersucht, wie Schülerinnen und Schüler der Jahrgangsstufen 4–6 (N = 866) beim Lösen von zwei Aufgaben aus unterschiedlichen Inhaltsbereichen – Arithmetik und Geometrie – argumentieren. Dazu wurden zwei Aufgaben entlang verschiedener theoretisch hergeleiteter Teilkompetenzen mathematischen Argumentierens entwickelt und in Teilaufgaben strukturiert. Zudem wurde geprüft, ob sich Unterschiede zwischen den drei Jahrgangsgruppen nachweisen lassen. Um die Bearbeitung der Begründungsaufgaben bezüglich zentraler inhaltlicher Merkmale beschreiben zu können, wurde entlang theoretischer Grundlagen ein Kategoriensystem entwickelt, das sowohl verschiedene Teilkompetenzen mathematischen Argumentierens in den Blick nimmt als auch die von den Schülerinnen und Schülern genutzten inhaltlichen Ideen erfasst und diese Bearbeitungsmerkmale jeweils bezüglich ihrer Ausführungsqualität einschätzt. Bei der Anwendung des Kategoriensystems ergab sich eine zufriedenstellende bis gute Interraterreliabilität. Vorgestellt werden Ergebnisse zu gezeigten Teilkompetenzen mathematischen Argumentierens sowie einbezogenen inhaltlichen Ideen für das Lösen der beiden Aufgaben. Die Befunde legen nahe, dass der Inhaltsbereich für die Bearbeitung in verschiedener Hinsicht eine Rolle spielt und dass sich die drei Jahrgangsstufen bezüglich verschiedener Merkmale der Bearbeitung voneinander unterscheiden.
“Good” choices vs “what really works”: a comparison of evidence-based practice in medicine and education
Authors: McKnight Lucinda , Morgan Andy 
Published: February 2022

AbstractEvidence-based practice, in a form which draws predominantly on quantitative research and privileges randomised controlled trials as research methods, has been translated from medicine into education. It follows that combining understanding of both disciplines may contribute to insights into the costs and benefits of this project. This article shares findings from a small study initiated by a medical doctor and teacher educator to compare versions of practice and professionalism offered by two texts from our respective disciplines. These texts advocate evidence-based practice for patients and students with disability and/or special needs. We describe our methodology and methods for interdisciplinary comparative textual analysis and share how this comparison contributes to understanding ways evidence-based practice is performed in education. In particular, we compare the versions of professionalism imagined in these cases and ask questions for policy and practice about motivations for the choices made in the apparently neutral process of “translation”.
A Building Classification System for Multi-hazard Risk Assessment

Published: February 2022

AbstractA uniform and comprehensive classification system, often referred to as taxonomy, is fundamental for the characterization of building portfolios for natural hazard risk assessment. A building taxonomy characterizes assets according to attributes that can influence the likelihood of damage due to the effects of natural hazards. Within the scope of the Global Earthquake Model (GEM) initiative, a building taxonomy (GEM Building Taxonomy V2.0) was developed with the goal of classifying buildings according to their seismic vulnerability. This taxonomy contained 13 building attributes, including the main material of construction, lateral load-resisting system, date of construction and number of stories. Since its release in 2012, the taxonomy has been used by hundreds of experts working on exposure and risk modeling efforts. These applications allowed the identification of several limitations, which led to the improvement and expansion of this taxonomy into a new classification system compatible with multi-hazard risk assessment. This expanded taxonomy (named GED4ALL) includes more attributes and several details relevant for buildings exposed to natural hazards beyond earthquakes. GED4ALL has been applied in several international initiatives, enabling the identification of the most common building classes in the world, and facilitating compatibility between exposure models and databases of vulnerability and damage databases.
Telemedicine monitoring in the follow-up of kidney transplant recipients: consensus indications from an Italian panel of surgeons and nephrologists after the COVID-19 experience

AbstractThe quality of follow-up has clearly emerged as a key factor for long-term kidney graft survival. Currently, many clinics are facing difficulties in delivering optimal surveillance because of the increased number and complexity of kidney transplant recipients, and because of the COVID-19 pandemic. Additional ways of performing follow-up visits are needed and telemedicine has emerged as a tool to strengthen patient care intensity. Six Italian transplant surgeons and nephrologists convened via teleconference to develop a consensual model of video visits for the follow-up of kidney transplant recipients. Issues discussed were: profile of eligible patients; assessments that can be carried out; video visit organization and medical professionals involved; supporting tools and implementation. The video visit was consensually recognized as the most relevant for the follow-up of kidney transplant recipients. Eligible patients should have basic electronic devices and the skills to correctly use them and be in clinically stable condition. With the exception of physical and instrumental examination, and kidney biopsy, all other assessments are feasible during a video visit and can be implemented by specific training and use of supporting tools. The video visit model is simple and adaptable to most transplant patients. It is not intended to replace face-to-face examinations, but is an additional tool for improving the intensity of follow-up of kidney transplant recipients, which can be integrated into current monitoring protocols.

Published: February 2022

AbstractIn addition to being used as an energy source, coal also has significant potential for other, more sustainable uses including water treatment. In this study, we present a simple approach to treat water that was produced during oil production and contained a total dissolved solids (TDS) content of over 150 g/L using Powder River Basin (PRB) coal. PRB coal used as packing material in a flow-through column effectively removed 60%–80% of the cations and anions simultaneously. Additionally, 71%–92% of the total organic carbon in the produced water was removed as was all of the total suspended solids. The removal mechanisms of both cations and anions were investigated. Cations were removed by ion exchange with protons from oxygen-containing functional groups such as carboxylic and phenolic hydroxyl groups. Anions, mainly Cl−1, appeared to be removed through either the formation of resonance structures as a result of delocalization of electrons within coal molecules or through ion–π interactions. We propose that coal is a “pseudo-amphoteric” exchange material that can remove cations and anions simultaneously by exchanging ions with both ionized and non-ionized acids that are ubiquitous in coal structure or resonance effect.

Architecture Design and Reliability Evaluation of a Novel Software-Defined Train Control System
Authors: Chang Ming , Nan Nan , Ou Dongxiu , Zhang Lei 
Published: February 2022

AbstractCommunication-based train control (CBTC) has been the prevailing technology of the urban transit signaling system. However, CBTC also faces a few issues to extend and maintain because of its complicated structure. This paper presents a novel urban transit signaling system architecture, software-defined train control (SDTC), which is based on cloud and high-speed wireless communication technology. The core functions of the proposed SDTC, including the onboard controller, are implemented in the cloud platform, with only sensors and input–output (IO) units remaining on the trackside and the train. Because of the scalable framework, the system function can be expanded according to the user’s demand, making signaling as a service possible. With warm standby server redundancy, SDTC has better reliability. Compared with the traditional CBTC architecture, the mean time between failures is improved by 39% by calculating typical project parameters by the Markov model based on some assumptions.
Knowledge building process during collaborative research ethics training for researchers: experiences from one university
Authors: Tammeleht Anu , Koort Kairi , Rodríguez-Triana María Jesús , Löfström Erika 
Published: February 2022

AbstractWhile research ethics and developing respective competencies is gaining prominence in higher education institutions, there is limited knowledge about the learning process and scaffolding during such training. The global health crisis has made the need for facilitator-independent training materials with sufficient support even more pronounced. To understand how knowledge building takes place and how computer-supported collaborative learning (CSCL) supports research ethics learning, we analysed: 1) how the participants’ understanding was displayed during the collaborative learning process utilising the developed ethics resource; and 2) whether the scaffolding provided by the resource supported the learning process. Epistemic evidence was collected during design-based research (DBR) involving 36 PhD students and researchers with supervisory experience divided into 11 groups. Data (from written group reports, group discussion recordings and self-reflection questionnaires) was analysed qualitatively utilising the SOLO taxonomy. The results revealed that: 1) participants displayed high levels of understanding and the need for the facilitator support decreased with the use of the online ethics resource; 2) the learners were able to evaluate their learning outcomes with satisfactory accuracy; 3) when used linearly, the online ethics resource helped learners to achieve high levels of understanding even when the scaffolding gradually faded. Based on the lessons learnt, design principles were extracted to develop research ethics competencies in higher education, and also recommendations for research ethics training were outlined.
“Trying as Hard as I Can”– Narratives of Failure and Success in the Experience of Housing Insecurity
Authors: Wolf Hannah 
Published: February 2022

AbstractThe housing crisis represents a liminal experience: a loss of the taken-for-granted and the suspension of ontological security has put individuals in a situation of potentiality in which both conceptions of home and of personal identity are open to transformation. Empirically assessing this liminal transition allows us to understand the refiguration processes of both home and subjectivities. This has both conceptual and political implications: with ongoing individualization of responsibility in virtually all spheres of social life, it is no longer possible to assume that the private sphere of home is an arena in which individuals are free and secured from societal forces, pressures, and compulsions. Instead, we might find ourselves in a transient liminal period in which the very meaning and psycho-social foundation of home are being transformed. To understand these processes is not only an epistemological but also a political endeavor, for only by understanding the psycho-social implications of the housing crisis can we acknowledge its embeddedness in and relation to processes of societal individualization, as well as the potential to open up pathways to the emergence of a liminal communitas.
