Published: November 2020

Abstractp-Nitroaniline (PNAN) and nitrobenzene (NB) being important raw materials and intermediates for the production of a wide range of chemical products have the potential of constituting water pollutants. Hence, the development of the means of removing these chemicals from water would go a long way to safeguard the health of the environment. The goal of this research was to transform bagasse fly ash (BFA), solid waste from the sugar industry into porous zeolitic adsorbents MgFZBFA and MgMZBFA and examine them for their adsorptive removal of PNAN and NB from aqueous solutions. The syntheses of the sorbents involve alkali fusion technique and microwave hydrothermal treatment for the desired properties. Advanced characterization techniques such as FTIR (Fourier transform infrared spectroscopy), XRF (X-ray fluorescence spectroscopy), XRD (X-ray diffraction spectroscopy), SEM (scanning electron microscopy), Brunauer–Emmett–Teller (BET)/Barrett–Joyner–Halenda (BJH) Method, and TGA (thermogravimetric analysis) were used for the characterization and evaluation of the sorbents’ properties. The adsorptive removal of PNAN and NB from aqueous solutions by MgFZBFA and MgMZBFA were investigated. Various parameters such as pH, adsorbent dosage, initial sorbate concentration were optimized during the adsorption experiment to achieve best performance. Adsorption isotherm, kinetics and dynamics were studied. It was found that Langmuir adsorption isotherm model better represents the adsorption processes and that the processes follow pseudo-second-order kinetics. More so, the sorption processes were most possibly completed by both surface sorption (liquid-film diffusion) and intra-particle diffusion. The maximum sorption capacities observed with MgFZBFA for PNAN and NB are 30.86 mg g−1and 19.92 mg g−1, while with MgMZBFA the values are 12.72 mg g−1and 10.20 mg g−1, respectively. The performances of MgFZBFA and MgMZBFA for the sorption of PNAN and NB were compared with some adsorbents previously studied for the same purpose, and results show that the adsorbents in the present study exhibit better performances. The application as materials of cheap source for the removal of PNAN and NB from contaminated water could be considered.
Design of Cloud Computing and Microservice-Based Urban Rail Transit Integrated Supervisory Control System Plus

Published: November 2020

AbstractIn traditional metro weak current systems, subsystems built by different manufacturers are physically separated, and devices are redundant while data are isolated. This causes low resource use, high maintenance cost, long customization cycles, and high interface complexity. In this paper, based on an analysis of the problems in traditional metro weak current systems, a novel cloud and microservice-based urban rail transit integrated supervisory control system (ISCS) named ISCS Plus is proposed. The integration mode of each subsystem is determined by analyzing safety requirements, real-time performance, and business characteristics. An infrastructure platform is designed to share resources and isolate applications based on cloud computing technology, while traditional subsystems are decomposed as microservices and merged into different applications. Finally, the entire architecture of ISCS Plus is established and its features are discussed. ISCS Plus plays a key role in the systematic, intelligent, and automatic solution for metro weak current systems and supports the development of the world's leading metro weak current systems.
How does crop insurance influence pesticide use? Evidence from French farms
Authors: Enjolras Geoffroy , Aubert Magali 
Published: November 2020

AbstractThe purpose of this paper is to examine how crop insurance influences pesticide use, the two decisions being strategic for risk management at the farm scale. To that aim, the paper implements propensity score matching, difference-in-differences models, and a combination of these two methods in order to compare two similar populations of insured and non-insured farmers. Using data from the Farm Accountancy Data Network (FADN), we consider French farms which cultivate field crops and quality wine-growing, the two main productions that participate the most to crop insurance and that use intensively pesticides. The analysis is performed between 2008 and 2012 given a strategic change in the crop insurance system in 2010 that strongly incites farmers to purchase crop insurance with private companies. At the same time, pesticide use was progressively discouraged through public policies. Estimations show that while pesticide use decreases for all crops, the purchase of crop insurance policies has no impact for field crops and quality wine-growing. Meanwhile, the land allocated to each crop within the farm changes. These results question a possible substitutability, for some productions, between crop insurance and pesticides as risk management tools.
Die unklare Nierenraumforderung: wie weiter?
Authors: Katsios Andreas , Thalmann George N. , Gross Tobias 
Published: November 2020

ZusammenfassungRaumforderungen der Niere sind eine heterogene Gruppe von benignen und malignen Tumoren. Eine entscheidende Rolle bei der weitergehenden Differenzierung und auch Überwachung spielt die Bildgebung. In gewissen Fällen kann eine Biopsie sinnvoll sein, insbesondere bei der Abklärung von metastasierten Leiden oder vor ablativen Verfahren zur Gewinnung einer Histologie. Bei T1/T2-Tumoren sollte, wenn immer vertretbar, eine Nierenteilresektion angestrebt werden, die minimal-invasiven Operationen sind zunehmend die Modalität der Wahl, jedoch sollte die minimal-invasive Methode nicht auf Kosten eines Nierenerhalts forciert werden. Bei älteren und komorbiden Patienten mit kleinen Nierentumoren ist die aktive Überwachung eine valide Alternative zur unmittelbaren Chirurgie.
Space Exploration: Approaches to Inhabiting Digital Spaces and Their Influence on Education
Authors: Calder Nigel , Otrel-Cass Kathrin 
Published: November 2020

AbstractWhat happens when we go online, interact and leave our digital footprints? What is the nature of the online spaces that teachers and their students inhabit and the implications of being in these spaces? In this article we have explored these questions by following the theoretical inspirations by James Paul Gee about affinity spaces and Martin Heidegger’s notions on dwelling. The article interweaves its argument with examples from several research projects to argue that online environments allow for opportunities to play and personalize, to be creative, and that these forms of expressions are an interplay of social and technical elements. While the control within digital spaces is not transparent, we contend that there are opportunities for the user to exert influence on and within digital spaces, and to transform them in varying ways and scope. Sometimes those spaces facilitate autonomy and self-selection, which in turn initiates or confirms transformation. With the growth and increased sophistication of virtual realities and artificial intelligence, we need to understand the nature of the educational engagement within these spaces. We also need to understand this mutually influencial engagement between the user and these digital spaces, and be vigilant as to who might be exerting the most influential control.
The educational outcomes of children in care – a scoping review
Authors: Lund Stephan , Stokes Cathy 
Published: November 2020

AbstractThis article presents a brief scoping review of the literature on the educational outcomes of care experienced children and young people in Australia published since 2010. The review also examines key educational issues and the impact of being in care on the educational experience of children and young people. Twenty-five papers were selected for review, key information extracted and recurrent themes noted. Themes include stigma and low expectations, school disruption and absenteeism, issues within the care and education systems and the importance of good relationships with supportive adults. The review found that young people in care often experience much worse educational outcomes than their peers. Conclusions and recommendations include reforming the care and education systems, focussing workers on building strong supportive relationships with young people, helping them to build resilience and prioritising education. Further targeted research is also recommended.
Do simple syntactic heuristics to verb meaning hold up? Testing the structure mapping account over spontaneous speech to Spanish-learning children
Authors: Audisio Cynthia Pamela , Migdalek Maia Julieta 
Published: November 2020

AbstractExperimental research has shown that English-learning children as young as 19 months, as well as children learning other languages (e.g., Mandarin), infer some aspects of verb meanings by mapping the nominal elements in the utterance onto participants in the event expressed by the verb. The present study assessed this structure or analogical mapping mechanism (SAMM) on naturalistic speech in the linguistic environment of 20 Spanish-learning infants from Argentina (average age 19 months). This study showed that the SAMM performs poorly – at chance level – especially when only noun phrases (NPs) included in experimental studies of the SAMM were parsed. If agreement morphology is considered, the performance is slightly above chance but still very poor. In addition, it was found that the SAMM performs better on intransitive and transitive verbs, compared to ditransitives. Agreement morphology has a beneficial effect only on transitive and ditransitive verbs. On the whole, concerns are raised about the role of the SAMM in infants’ interpretation of verb meaning in natural exchanges.
Childhood exposure to interpersonal violence is associated with greater transdiagnostic integration of psychiatric symptoms

Published: November 2020

AbstractBackgroundChildhood exposure to interpersonal violence (IPV) may be linked to distinct manifestations of mental illness, yet the nature of this change remains poorly understood. Network analysis can provide unique insights by contrasting the interrelatedness of symptoms underlying psychopathology across exposed and non-exposed youth, with potential clinical implications for a treatment-resistant population. We anticipated marked differences in symptom associations among IPV-exposed youth, particularly in terms of ‘hub’ symptoms holding outsized influence over the network, as well as formation and influence of communities of highly interconnected symptoms.MethodsParticipants from a population-representative sample of youth (n= 4433; ages 11–18 years) completed a comprehensive structured clinical interview assessing mental health symptoms, diagnostic status, and history of violence exposure. Network analytic methods were used to model the pattern of associations between symptoms, quantify differences across diagnosed youth with (IPV+) and without (IPV–) IPV exposure, and identify transdiagnostic ‘bridge’ symptoms linking multiple disorders.ResultsSymptoms organized into six ‘disorder’ communities (e.g.Intrusive Thoughts/Sensations, Depression, Anxiety), that exhibited considerably greater interconnectivity in IPV+ youth. Five symptoms emerged in IPV+ youth as highly trafficked ‘bridges’ between symptom communities (11 in IPV– youth).ConclusionIPV exposure may alter mutually reinforcing symptom co-occurrence in youth, thus contributing to greater psychiatric comorbidity and treatment resistance. The presence of a condensed and unique set of bridge symptoms suggests trauma-enriched nodes which could be therapeutically targeted to improve outcomes in violence-exposed youth.
Limits on expectation-based processing: Use of grammatical aspect for co-reference in L2
Authors: Grüter Theres , Rohde Hannah 
Published: November 2020

AbstractThis study examines the use of discourse-level information to create expectations about reference in real-time processing, testing whether patterns previously observed among native speakers of English generalize to nonnative speakers. Findings from a visual-world eye-tracking experiment show that native (L1;N= 53) but not nonnative (L2;N= 52) listeners’ proactive coreference expectations are modulated by grammatical aspect in transfer-of-possession events. Results from an offline judgment task show these L2 participants did not differ from L1 speakers in their interpretation of aspect marking on transfer-of-possession predicates in English, indicating it is not lack of linguistic knowledge but utilization of this knowledge in real-time processing that distinguishes the groups. English proficiency, although varying substantially within the L2 group, did not modulate L2 listeners’ use of grammatical aspect for reference processing. These findings contribute to the broader endeavor of delineating the role of prediction in human language processing in general, and in the processing of discourse-level information among L2 users in particular.

AbstractObjectiveTelemedicine uses information and communication technologies to provide services in the field where the distance is a critical factor. The aim of the present study is to describe the experience of a synchronous telemedicine between two hospitals in Spain and Angola.MethodsThis is a retrospective observational study of all synchronous telemedicine sessions conducted between the Hospital Nossa Senhora da Paz in Angola and the Vall d'Hebron University Hospital in Spain from January 2011 to December 2014.ResultsSeventy-two cases were discussed in the telemedicine sessions. The average age of patients was 18.02 (SD 13.75) years and mostly women (54.38 percent). Reasons to discuss the cases were 46.47 percent doubts in the diagnosis and therapeutic management, 15.47 percent were purely formative cases, and only 8.45 percent treatment doubt. At the time of presentation, 29 percent of the patients were already diagnosed, 95 percent of whom with infectious disease diagnostic, and from the undiagnosed patients 36 percent presented a febrile syndrome.ConclusionThis study shows the viability of synchronous telemedicine between European and African countries without an excessively sophisticated technology.
Not teaching what we practice: undergraduate conservation training at UK universities lacks interdisciplinarity
Authors: Gardner Charlie J 
Published: November 2020

SummaryThe practice and science of conservation have become increasingly interdisciplinary, and it is widely acknowledged that conservation training in higher education institutions should embrace interdisciplinarity in order to prepare students to address real-world conservation problems. However, there is little information on the extent to which conservation education at the undergraduate level meets this objective. I carried out a systematic search of undergraduate conservation degree programmes in the UK and conducted a simple text analysis of module descriptions to quantify the extent to which they provide social science training. I found 47 programmes, of which 29 provided module descriptions. Modules containing social science content ranged from 3.8% to 52.2% of modules across programmes, but only 55.2% of programmes offered a social-focused conservation module, and only one programme offered a module in social science research methods. On average, almost half of the modules offered (46.2%) comprised biology and ecology modules with no conservation focus, and 17.9% comprised skills-based modules (research and vocational skills). Conservation-focused modules comprised a mean of only 22.5% of modules. These results show that undergraduate conservation teaching in the UK is still largely biocentric and is failing to deliver the interdisciplinary education that is widely called for.

AbstractImpairment in reciprocal social behavior (RSB), an essential component of early social competence, clinically defines autism spectrum disorder (ASD). However, the behavioral and genetic architecture of RSB in toddlerhood, when ASD first emerges, has not been fully characterized. We analyzed data from a quantitative video-referenced rating of RSB (vrRSB) in two toddler samples: a community-based volunteer research registry (n = 1,563) and an ethnically diverse, longitudinal twin sample ascertained from two state birth registries (n = 714). Variation in RSB was continuously distributed, temporally stable, significantly associated with ASD risk at age 18 months, and only modestly explained by sociodemographic and medical factors (r2 = 9.4%). Five latent RSB factors were identified and corresponded to aspects of social communication or restricted repetitive behaviors, the two core ASD symptom domains. Quantitative genetic analyses indicated substantial heritability for all factors at age 24 months (h2 ≥ .61). Genetic influences strongly overlapped across all factors, with a social motivation factor showing evidence of newly-emerging genetic influences between the ages of 18 and 24 months. RSB constitutes a heritable, trait-like competency whose factorial and genetic structure is generalized across diverse populations, demonstrating its role as an early, enduring dimension of inherited variation in human social behavior. Substantially overlapping RSB domains, measurable when core ASD features arise and consolidate, may serve as markers of specific pathways to autism and anchors to inform determinants of autism's heterogeneity.
Functional brain abnormalities associated with comorbid anxiety in autism spectrum disorder
Authors: Bartolotti James , Sweeney John A. , Mosconi Matthew W. 
Published: November 2020

AbstractAnxiety disorders are common in autism spectrum disorder (ASD) and associated with social–communication impairment and repetitive behavior symptoms. The neurobiology of anxiety in ASD is unknown, but amygdala dysfunction has been implicated in both ASD and anxiety disorders. Using resting-state functional magnetic resonance imaging, we compared amygdala–prefrontal and amygdala–striatal connections across three demographically matched groups studied in the Autism Brain Imaging Data Exchange (ABIDE): ASD with a comorbid anxiety disorder (N= 25; ASD + Anxiety), ASD without a comorbid disorder (N= 68; ASD-NoAnx), and typically developing controls (N= 139; TD). Relative to ASD-NoAnx and TD controls, ASD + Anxiety individuals had decreased connectivity between the amygdala and dorsal/rostral anterior cingulate cortex (dACC/rACC). The functional connectivity of these connections was not affected in ASD-NoAnx, and amygdala connectivity with ventral ACC/medial prefrontal cortex (mPFC) circuits was not different in ASD + Anxiety or ASD-NoAnx relative to TD. Decreased amygdala–dorsomedial prefrontal cortex (dmPFC)/rACC connectivity was associated with more severe social impairment in ASD + Anxiety; amygdala–striatal connectivity was associated with restricted, repetitive behavior (RRB) symptom severity in ASD-NoAnx individuals. These findings suggest comorbid anxiety in ASD is associated with disrupted emotion-monitoring processes supported by amygdala–dACC/mPFC pathways, whereas emotion regulation systems involving amygdala–ventromedial prefrontal cortex (vmPFC) are relatively spared. Our results highlight the importance of accounting for comorbid anxiety for parsing ASD neurobiological heterogeneity.

Published: November 2020

AbstractProspective longitudinal studies of idiopathic autism spectrum disorder (ASD) have provided insights into early symptoms and predictors of ASD during infancy, well before ASD can be diagnosed at age 2–3 years. However, research on the emergence of ASD in disorders with a known genetic etiology, contextualized in a developmental framework, is currently lacking. Using a biobehavioral multimethod approach, we (a) determined the rate of ASD in N = 51 preschoolers with fragile X syndrome (FXS) using a clinical best estimate (CBE) procedure with differential diagnoses of comorbid psychiatric disorders and (b) investigated trajectories of ASD symptoms and physiological arousal across infancy as predictors of ASD in preschoolers with FXS. ASD was not diagnosed if intellectual ability or psychiatric disorders better accounted for the symptoms. Our results determined that 60.7% of preschoolers with FXS met the Diagnostic and Statistical Manual of Mental Disorders (fifth edition) (DSM-5) criteria for ASD using the CBE procedure. In addition, 92% of these preschoolers presented with developmental delay and 45.4% also met criteria for psychiatric disorders, either anxiety, ADHD, or both. ASD diagnoses in preschoolers with FXS were predicted by elevated scores on traditional ASD screeners in addition to elevated autonomic arousal and avoidant eye contact from infancy.
