An overview of sedimentary volcanism on Mars
Authors: Brož Petr , Oehler Dorothy , Mazzini Adriano , Hauber Ernst , Komatsu Goro , Etiope Giuseppe , Cuřín Vojtěch
Published: January 2023

Abstract. Extensive fields of sub-kilometre-to kilometre-scale mounds, cones, domes, shields, and flow-like edifices cover large parts of the martian lowlands. These features have been compared to structures on Earth produced by sedimentary volcanism – a process that involves subsurface sediment/fluid mobilization and commonly releases methane to the atmosphere. It was proposed that such process might help to explain the presence of methane in martian atmosphere and also may have additionally produced habitable, subsurface settings of potential astrobiological relevance. However, it remains unclear whether sedimentary volcanism on Earth and Mars share genetic similarities; hence whether methane, or other gases were released on Mars during this process. The aim of this review is to summarize the current knowledge about mud-volcano-like structures on Mars, address the critical aspects of this process, identify key open questions, and point to areas where further research is needed to understand this phenomenon and its importance for the red planet’s geological evolution. We show here that after several decades of exploration, the amount of evidence supporting a martian sedimentary volcanism scenario has increased significantly, but as critical ground truth is still lacking, alternative explanations cannot always be ruled out. We also highlight that the lower gravity and temperatures on Mars compared to Earth control the dynamics of clastic eruptions as well as surface emplacement and resulting morphologies of erupted material. This implies that shapes and triggering mechanisms of mud-volcano-like structures may be different from those observed on Earth. Therefore comparative studies should be done with caution. To provide a better understanding of the significance of these abundant features on Mars, we argue for follow-up studies targeting putative sedimentary volcanic features identified on the planet’s surface and, if possible, for in situ investigations by landed missions such as that currently in progress by the Zhurong rover.
Floods and droughts: a multivariate perspective on hazard estimation
Authors: Brunner Manuela Irene
Published: January 2023

Abstract. Multivariate hydrological extreme events such as successive floods, large-scale droughts, or consecutive drought-to-flood events challenge water management and can be particularly impactful. Still, the multivariate nature of floods and droughts is often ignored by studying them from a univariate perspective, which can lead to risk under- or overestimation. Studying multivariate extremes is challenging because of variable dependencies and because they are even less abundant in observational records than univariate extremes. In this review, I discuss different types of multivariate hydrological extremes and their dependencies including regional extremes affecting multiple locations such as spatially connected flood events, consecutive extremes occurring in close temporal succession such as successive droughts, extremes characterized by multiple characteristics such as floods with jointly high peak discharge and flood volume, and transitions between different types of extremes such as drought-to-flood transitions. I present different strategies to describe and model multivariate extremes, and to assess their hazard potential including multivariate distributions and return periods as well as stochastic and large-ensemble simulation approaches. The strategies discussed enable a multivariate perspective in hydrological hazard assessments, which allows us to derive more comprehensive risk estimates than the classical univariate perspective commonly applied.
Cloud-radiative impact on the dynamics and predictability of an idealized extratropical cyclone
Authors: Keshtgar Behrooz , Voigt Aiko , Hoose Corinna , Riemer Michael , Mayer Bernhard
Published: January 2023

Abstract. Extratropical cyclones drive midlatitude weather, including extreme events, and determine midlatitude climate. Their dynamics and predictability are strongly shaped by cloud diabatic processes. While the cloud impact due to latent heating is much studied, little is known about the impact of cloud radiative heating (CRH) on the dynamics and predictability of extratropical cyclones. Here, we address this question by means of baroclinic life cycle simulations performed at a convection-permitting resolution of 2.5 km with the ICON model. The simulations use a newly implemented channel setup with periodic boundary conditions in the zonal direction. Moreover, the simulations apply a new modeling technique for which only CRH interacts with the cyclone, which circumvents changes in the mean state due to clear-sky radiative cooling that has complicated the interpretation of previous work. We find that CRH increases the kinetic energy of the cyclone system. The impact is most prominent at upper levels. To understand the CRH impact on the upper-tropospheric circulation, we diagnose the evolution of differences in potential vorticity between a simulation with and without CRH, and we quantify through which processes these differences grow over the course of the cyclone's life cycle. According to this diagnostic, CRH affects the cyclone mostly via the intensification of latent heating from cloud microphysical processes. Near the tropopause, direct diabatic modification of potential vorticity by intensified latent heat release precedes further changes in the tropopause by the upper-tropospheric divergent flow, which represents an indirect impact of latent heat release. Subsequently, differences in the tropopause structure amplify with the rotational flow during the highly nonlinear stage of the baroclinic wave. Our results show that although CRH is comparably small in magnitude, it can affect extratropical cyclones by changing cloud microphysical heating and subsequently the large-scale flow. The CRH impact follows a previously identified mechanism of multi-stage upscale error growth. At the same time, simulations in which CRH is disabled after certain days show that the CRH impact operates throughout the entire intensification phase of the cyclone. This means that CRH does not merely provide an arbitrary initial perturbation to the cyclone, from which differences grow in a generic way. Instead, our results suggest that uncertainties associated with the representation of CRH in numerical models have a more systematic impact and may more fundamentally influence model predictions of extratropical cyclones.
A Soul-searching assembly: Vignette
Authors: Marjanovic-Shane Ana
Published: January 2023

In this article, I develop a dialogic analysis of a democratic school’s General Assembly meeting in the form of a vignette. As a qualitative method, a vignette is a suitable way of preparing evidence and constructing data for further analyses. It is also an ideal medium for a full-fledged dialogic analysis of the described events and dialogues that took place among the participants. I grounded this vignette on a transcript of an audio recording of a General Assembly meeting held in the first Norwegian democratic high school – the Experimental Gymnasium of Oslo (EGO) on November 2nd, 1967, shortly after it started to work in 1967. Using the students’ voices raised in this meeting, I aimed to recreate the meeting’s dramatic atmosphere. My approach follows the art of dialogic analysis (Matusov, Marjanovic-Shane, & Gradovski, 2019; Matusov, Marjanovic-Shane, Kullenberg, & Curtis, 2019), as I attempt to dialogically join the students, adding my reactions and interpretations of the meeting’s unfolding debates and dialogues. I also add my dialogic replies to the students and insert other comments judging their positions dialogically in an attempt to also create rich data for further conceptual analysis, which is published in another article in this special issue, “Paradigmatic dialogue-disagreement in a democratic school: A conceptual analysis” (see Marjanovic-Shane, 2023b).
A paradigmatic dialogue-disagreement in a democratic school: A conceptual analysis of a soul-searching assembly meeting
Authors: Marjanovic-Shane Ana
Published: January 2023

In this article, I attempt to conceptually analyze points of disagreement among the students of the first democratic high school in Norway, The Experimental Gymnasium of Oslo (EGO). The clashes and disagreements among the students started heating up immediately after the school was opened in the fall of 1967. As they were learning how to run their school, the students discovered profound differences in their views of education and its purposes. Their deep disagreements about the meaning of education and conflicts about their school practices almost broke up their school right at the very start of its existence.
Their different understandings of education erupted in a passionate and dramatic general assembly meeting, which they later referred to as the Soul-Searching Assembly. This four-and-a-half hour-long meeting was recorded and its transcript was published (Hem & Remlov, 1969). In this article, I analyze the dialogues from the assembly, looking for the students’ diverse ideological and conceptual positions, views, desires, and underlying values. The tensions and clashes the students voiced echo the profound paradigmatic differences in conceptualizing education throughout the modern history of education, from the Enlightenment until now, a few decades into the 21st century. The purpose of my analysis is to examine these paradigmatically different views and the concerns behind them. These radically different paradigmatic, conceptual, and axiological positions have an effect on what we may consider being good, ethical, just, and true for human existence, human relationships, and human rights in general, and especially in education. The EGO students’ intensive and urgent ontological need to explain their very different positions to each other allowed me to take a closer look into the tensions and conflicts still existing in the larger cultural-historical public sphere of discourse on education.

The Effect of Managerial Ability on relationship between Risk Taking Ability of a Firm and its Financial Performance in Pakistan
Authors: Ahmed Waqar , Shah Ansar Abbas , Iqbal Mazhar , Arshad Arooj
Published: January 2023

The purpose of this research was to address this vacuum in the literature by examining the moderating effect of management competence on business performance and managerial efficiency. The aim of this research is to examine whether the level of managerial skill in a company affects the correlation between the willingness to take risks and the company's financial success. Method: a sample of 100 businesses listed on the KSE 100 Index in Pakistan from 2014-2020 have been considered to examine the influence of managerial skill in light of the fact that risk management is essential to improving company performance. Stata was used to do data envelopment analysis, and then the findings were analysed using random effect panel regression to determine a company's efficiency. The results indicate that there is a positive correlation between managers' risk-taking abilities and the success of their companies, as those with greater abilities are better equipped to exploit opportunities while keeping their organizations' risks to a minimum. This study fills in a lot of blanks in the literature by explaining how a company may be affected by the skills of its managers. Furthermore, this research tackles the existing inconsistent literature and bridges the previous literature gap between risk-taking behaviour and firm performance by including management competence as a component in developing successful risk mitigation plan.

Published: January 2023

Composite is a composite material consisting of two or more materials with different mechanical properties. Composite materials are mixed to obtain new materials that have better micro-mechanical properties. To facilitate the mixing of composite materials and obtain materials that have good quality, in this study, a mixer machine design with heating elements was carried out so that the temperature could be adjusted as needed. Experiments from the results of a mixer machine with a heating element that have been made are comparing the mixing of resin and iron sand using a mixer machine without a heating element and using a heating element. The result of mixing composite materials using a mixer machine without heating elements is that the composite material is homogeneously mixed but when viewed from the micro-photos there are still many white spots so that the quality of the composite material is still not good. then the composite material is mixed and mixed using a mixer machine with a heating element, the composite material is homogeneously mixed and after seeing from the micro-photos there are a few wite spots on the composite.

A New IDS for Detecting DDoS Attacks in Wireless Networks using Spotted Hyena Optimization and Fuzzy Temporal CNN
Authors: C. M. Nalayini C. M. Nalayini , C. M. Nalayini Jeevaa Katiravan
Published: January 2023

Cyber-attacks are rapidly increasing in the internet era due to the growth of information technology. The distributed denial of service (DDoS) attacks are increasing dramatically due to the distributed services in cloud networks. In this paper, a new Intrusion Detection System (IDS) is proposed to improve the performance of the networks by detecting DDoS attacks effectively in wireless networks. In this work, we propose a new feature selection method called Split Filter Feature Selection and Spotted Hyena Optimization Based Feature Optimization Method (SFSH-FOM) to select the most contributed features that are helpful for enhancing the classification accuracy. In this work, a new deep learning algorithm named Fuzzy Temporal Features incorporated Convolutional Neural Network (FT-CNN) is proposed for performing effective classification. Here, a new cross layer feature fusion technique is also proposed by using FT-CNN and LSTM for enhancing the performance. The experiments have been carried out to evaluate the proposed IDS using the standard datasets, namely the KDD’99 dataset, the NSL-KDD dataset, and the DDoS dataset by considering the evaluation metrics such as detection accuracy, recall, precision, and F1-score, and it has also been proved as better than other IDSs in terms of accuracy and false alarm rate.

 
Likinge: Julian of Norwich’s Theology of Pleasure
Authors: Millay Thomas J.
Published: January 2023

This article argues for the centrality of a neglected theme in the writings of Julian of Norwich: pleasure. To argue for the theme’s centrality, the author focuses on Julian’s Short Text, A Vision Showed to a Devout Woman. In the expanded Long Text, there are themes added unto pleasure; however, Julian’s theology of pleasure remains fundamental to the dynamic of the text. Looking at the Short Text enables us to see how the theme is established. When one pays attention to pleasure (or, in Julian’s English, likinge), its importance to the text is remarkable. In fact, the author argues that the transformation of pain into pleasure is a motif that is basic to Julian’s whole visionary experience. Characteristically, she also orchestrates a theology around the theme, connecting pleasure to God’s relation to human beings, the intertrinitarian relations, and how human beings are supposed to relate to themselves. In short: once this theme is highlighted, a rich theology of pleasure reveals itself.

Air pollution: a review of its economic effects and policies to mitigate them
Authors: Hospido Laura , Sanz Carlos , Villanueva Ernesto
Published: January 2023

Air pollution is an increasing cause of concern among the scientific community, policymakers and the general public. This interest has led to a sharp increase in the number of scientific papers on air pollution. This paper provides a summary of the most prominent recent economic literature on the effects of air pollution, the main policy lessons that can be drawn from it, and the areas in which more research would be especially valuable. The literature has found sizable negative effects of air pollution on health and mortality. There is also some evidence that air pollution may have negative non-health effects, reducing labour supply and productivity, although the evidence is more mixed on the latter aspect. The literature also suggests that effects on both health and non-health dimensions may be heterogeneous in a number of dimensions, most prominently age, with more negative effects for the elderly. Finally, more research is needed on which policies to tackle air pollution would be more cost-effective.

Quantitative evaluations of the microbial density of soils are important to understand the ecological relationships that occur and to identify factors that influence the microbiological balance. The objective was to quantify soil microorganisms in three different areas and use management. The work was carried out at the Federal Institute of Roraima, in three areas: gliricidia, orange and banana, orange and ipê consortium and forest area. Soil samples were collected at depths of 0-10 and 10-20 cm. The total microbiota was evaluated by the surface plating technique and quantified by colony forming units per gram of soil (CFU g soil-1). Plates were incubated at 28°C for 48 and 96 hours. Ammonifying, cellulolytic and actinobacteria organisms were quantified by soil suspension, using specific culture media. The results showed that the area of the intercropping gliricidia + orange and banana has a higher population of microorganisms, proving to be an alternative for intercropping systems with agricultural crops, providing greater biodiversity, in addition to providing nitrogen for the plants.

LE LINGUE DEI SEGNI NEL “VOLUME COMPLEMENTARE” E L’INSEGNAMENTO DELLA LIS NELLE UNIVERSITÀ ITALIANE
Authors: Cardinaletti Anna , Mantovan Lara
Published: January 2023

La lingua dei segni italiana (LIS) è oggetto di ricerca scientifica da oltre quaranta anni ed è insegnata a pieno titolo nell’Università italiana da più di venti anni. In particolare, all’Università Ca’ Foscari Venezia e all’Università di Catania, la LIS può essere scelta come lingua di specializzazione al pari delle altre lingue offerte. L’insegnamento della LIS si può ora giovare della recente pubblicazione del QCER - Volume Complementare (Consiglio d’Europa, 2020), un manuale innovativo e inclusivo perché, rispetto alla versione del 2001, include le competenze linguistiche nelle lingue dei segni. Tre sono le principali novità: i) l’inserimento di espressioni neutrali rispetto alla modalità comunicativa (es. “il parlante/segnante”), ii) l’equiparazione funzionale delle videoregistrazioni ai testi scritti, e iii) un intero capitolo dedicato ai descrittori specifici per le lingue dei segni (suddivisi in competenze linguistiche, sociolinguistiche e pragmatiche). Questo contributo propone alcune riflessioni sull’applicazione di questi descrittori al caso specifico dell’insegnamento della LIS tracciando precise linee di progettazione didattica ed esempi di interventi formativi. L’impatto del Volume Complementare sui corsi di LIS nelle Università italiane comporterà ricadute positive non soltanto sul fronte dell’insegnamento ma anche, più in generale, sulla formazione dei professionisti sordi e udenti che lavorano con la LIS e con le persone sorde.

 

Sign languages in the  Companion volume and the teaching of LIS in Italian universities

Italian Sign Language (LIS) has been studied by researchers for over forty years and has been taught in its own right in Italian universities for more than twenty years. In particular, at Ca’ Foscari University of Venice and at the University of Catania, LIS can be chosen as a language of specialization on a par with the other languages ​​on offer. LIS teaching can now benefit from the recent publication of the CEFR - Companion Volume (Council of Europe, 2020), an innovative and inclusive handbook as, compared to the 2001 version, it includes the linguistic competence in sign languages. In this regard, there are three main innovations: i) the inclusion of neutral expressions in terms of communication modality (e.g. “the speaker/signer”), ii) the recognition of the functional equivalence between video recordings and written texts, and iii) an entire chapter dedicated to language-specific descriptors of sign languages (organized into linguistic, sociolinguistic, and pragmatic skills). This paper discusses the application of these descriptors to the specific case of LIS teaching by tracing paths in didactic planning and providing examples of training interventions. The impact of the Companion Volume on LIS courses in Italian universities will have positive effects not only on the teaching itself but also, more generally, on the training of deaf and hearing professionals who work with LIS and deaf people.

Il progetto intende costituirsi come punto di riferimento per la raccolta, revisione e disseminazione degli italianismi rintracciati nelle diverse lingue del mondo. L’accurata descrizione e analisi dei risultati del contatto tra italiano e altre lingue (tipologicamente e storicamente diversificato a seconda delle lingue coinvolte) richiede approfondite considerazioni di tipo metodologico, filologico e lessicologico. Alla base del progetto – nella prospettiva di lessicografia digitale – si colloca il database contenente le raccolte di italianismi nelle lingue europee ed extraeuropee. Nel contributo presentato in questa sezione, diviso in due parti, si offre un panorama delle prospettive di ricerca messe a punto per il compito che attende i ricercatori e che caratterizzano attualmente il lavoro.  Nella sezione introduttiva si ricostruisce la storia del progetto, mentre nella successiva si descrive il funzionamento del database, i criteri usati per la raccolta degli italianismi e la presentazione delle entrate lessicografiche; si affrontano inoltre questioni legate alla semantica dei prestiti e si offre infine una panoramica delle prospettive future del progetto OIM.

The OIM project (Osservatorio degli Italianismi nel Mondo)

The Osservatorio degli Italianismi nel Mondo (OIM), an observatory of Italian loanwords in languages throughout the world, is among the strategic projects of the National Academy of the Italian language, Accademia della Crusca. The project is carried out by a vast international group of researchers and is intended to be a point of reference for the collection, review and dissemination of Italianisms found in many different languages worldwide. The accurate description and analysis of the results of multi-faceted and historically diverse language contact situations involving Italian as a donor language requires both methodological and in-depth lexical-philological considerations. The digital lexicographic tool which the project rests upon has at its core a database containing collections of Italianisms in both European and extra-European language varieties. This paper, divided into two main sections, provides an overview of the research perspectives that have eventually brought forth the OIM endeavor and characterize its current lines of work. In the introductory part the history of the project is recounted while the following parts address the set-up of the database, the criteria for collecting data on Italianisms, the lexicographical entries as well as semantic questions regarding loanwords and finally offer an outlook on future work within the OIM.

Synthesis of Plasma-Polymerized Toluene Coatings by Microwave Discharge
Authors: Elhamali Suleiman Musa
Published: January 2023

Plasma- polymerized coatings were successfully applied on aluminum alloy, AA2024, surface for corrosion protection. The plasma polymerization process was carried out by low pressure microwave plasma at room temperature. The effect of microwave plasma power on the corrosion resistance of polymer coatings was investigated using the potentiodynamic polarization technique. As the microwave plasma power increased, the relative protective efficiency increased. Polymer coatings on alloy surfaces suppressed both anodic and cathodic reactions. The increment in protective efficiency was due to a higher degree of cross-linking in the coating. These findings suggest that the toluene polymer coatings provide a considerable protection barrier for aluminum alloys.

Correlations Between Expressing Feelings, Conveying Thoughts, and Gaining Confidence when Writing Personal Narratives in One’s First and Second Language
Authors: Saaty Ahdab Abdalelah
Published: January 2023

This article aims to identify if writing personal narratives in one’s first and second language help in expressing feelings, conveying thoughts, and gaining confidence in writing. This study reflects a meaningful literacy approach focused on the individual language learner at the center of the learning process to facilitate writing development. Data came from current and former English majors who have taken creative writing courses. Participants were from private and public universities and a professional group on Facebook (N = 34). Data were collected through an online survey. Research questions were tested with statistical measures of correlations. Data were analyzed using SPSS. Descriptive statistics were used to check whether the data were normally distributed. Then, the Spearman rho test was used to check for correlations and covariance because the data were not normally distributed. Results revealed a correlation between expressing feelings, conveying thoughts, and gaining confidence when writing personal narratives in one’s first and second language. The findings can be applied in writing classrooms by integrating writing personal narratives to help students express feelings, convey thoughts, and gain confidence in writing. It is important for educators to understand how personal narrative writing supports students’ learning process in writing classes and beyond.

As leishmanioses são consideradas doenças negligenciadas devido às altas incidências, ampla distribuição geográfica e dificuldade no tratamento sendo incluídas na relação de doenças prioritárias pela Organização Mundial da Saúde. Os tratamentos disponíveis para estas doenças apresentam elevada toxicidade, justificando a busca por fármacos alternativos. Estudos prévios com própolis, resina produzida por abelhas, demonstraram sua atividade antiparasitária e imunomoduladora em diversos modelos experimentais. O objetivo deste trabalho foi avaliar o efeito in vitro do extrato hidroalcoólico de própolis brasileira, coletado na cidade de Botucatu no estado de São Paulo, sobre formas promastigotas de Leishmania amazonensis, bem como analisar seu efeito in vivo sobre a carga parasitária em baço de camundongos susceptíveis à infecção. Assim, formas promastigotas tratadas com extrato hidroalcoólico de própolis brasileira nas concentrações 5, 10, 25, 50 ou 100 µg/mL apresentaram efeito inibitório sobre a proliferação desses parasitos nos tempos de 24, 96 e 168 h. No entanto, as concentrações de 50 e 100 µg/mL mostraram-se mais eficazes quando comparadas ao controle e às demais concentrações em todos os tempos avaliados. Em relação à carga parasitária, após 30 dias de infecção com L. amazonensis, camundongos BALB/c foram tratados diariamente com a própolis (5mg/kg), via oral ou intraperitoneal, durante 60 dias. Posteriormente, o baço destes animais foi coletado para análise da carga parasitária. O tratamento por via oral reduziu 40% da carga parasitária. Desta forma, a amostra de própolis brasileira testada apresentou ação leishmanicida sobre L. amazonensis em cultura e em camundongos infectados com este protozoário.
