The classic classification scheme for active galactic nuclei (AGNs) was recently challenged by the discovery of the so-called changing-state (changing-look) AGNs. The physical mechanism behind this phenomenon is still a matter of open debate and the samples are too small and of serendipitous nature to provide robust answers. In order to tackle this problem, we need to design methods that are able to detect AGNs right in the act of changing state. Here we present an anomaly-detection technique designed to identify AGN light curves with anomalous behaviors in massive data sets. The main aim of this technique is to identify CSAGN at different stages of the transition, but it can also be used for more general purposes, such as cleaning massive data sets for AGN variability analyses. We used light curves from the Zwicky Transient Facility data release 5 (ZTF DR5), containing a sample of 230,451 AGNs of different classes. The ZTF DR5 light curves were modeled with a Variational Recurrent Autoencoder (VRAE) architecture, that allowed us to obtain a set of attributes from the VRAE latent space that describes the general behavior of our sample. These attributes were then used as features for an Isolation Forest (IF) algorithm that is an anomaly detector for a “one class” kind of problem. We used the VRAE reconstruction errors and the IF anomaly score to select a sample of 8809 anomalies. These anomalies are dominated by bogus candidates, but we were able to identify 75 promising CSAGN candidates.

Galactic supernova remnants (SNRs) with angular dimensions greater than a few degrees are relatively rare, as are remnants located more than 10° off the Galactic plane. Here we report a UV and optical investigation of two previously suspected SNRs more than 10° in both angular diameter and Galactic latitude. One is a proposed remnant discovered in 2008 through 1420 MHz polarization maps near Galactic coordinates l = 353°, b = −34°. GALEX far-UV (FUV) and Hα emission mosaics show the object’s radio emission coincident with an 11° × 14° shell of UV filaments that surrounds a diffuse Hα emission ring. Another proposed high-latitude SNR is the 20° × 26° Antlia nebula (G275.5+18.4) discovered in 2002 through low-resolution all-sky Hα and ROSAT soft X-ray emissions. GALEX FUV and Hα mosaics along with optical spectra indicate the presence of shocks throughout the Antlia nebula with estimated shock velocities of 70 to over 100 km s−1. We also present evidence that it has collided with the NE rim of the Gum Nebula. We find both of these large nebulae are bona fide SNRs with ages less than 105 yr despite their unusually large angular dimensions. We also present FUV and optical images along with optical spectra of a new high-latitude SNR (G249.7+24.7) some 4.5° in diameter which has also been independently discovered in X-rays and radio (Becker at al. 2021). We find this remnant’s distance to be ≤400 pc based on the detection of red and blue Na i absorption features in the spectra of two background stars.

Published: October 2021

In this study, we generate He i 1083 nm images from Solar Dynamic Observatory (SDO)/Atmospheric Imaging Assembly (AIA) images using a novel deep learning method (pix2pixHD) based on conditional Generative Adversarial Networks (cGAN). He i 1083 nm images from National Solar Observatory (NSO)/Synoptic Optical Long-term Investigations of the Sun (SOLIS) are used as target data. We make three models: single-input SDO/AIA 19.3 nm image for Model I, single-input 30.4 nm image for Model II, and double-input (19.3 and 30.4 nm) images for Model III. We use data from 2010 October to 2015 July except for June and December for training and the remaining one for test. Major results of our study are as follows. First, the models successfully generate He i 1083 nm images with high correlations. Second, Model III shows better results than those with one input image in terms of metrics such as correlation coefficient (CC) and root mean square error (RMSE). CC and RMSE between real and synthetic ones for model III with 4 by 4 binnings are 0.88 and 9.49, respectively. Third, synthetic images show well observational features such as active regions, filaments, and coronal holes. This work is meaningful in that our model can produce He i 1083 nm images with higher cadence without data gaps, which would be useful for studying the time evolution of the chromosphere and transition region.
Weather on Other Worlds. VI. Optical Spectrophotometry of Luhman 16B Reveals Large-amplitude Variations in the Alkali Lines

Published: October 2021

Using a novel wide-slit, multiobject approach with the GMOS spectrograph on the 8 m Gemini South telescope, we have obtained precise time-series spectrophotometry of the binary brown dwarf Luhman 16 at optical wavelengths over two full nights. The B component of this binary system is known to be variable in the red optical and near-infrared with a period of 5 hr and an amplitude of 5%–20%. Our observations probe its spectrally resolved variability in the 6000–10000 Å range. At wavelengths affected by the extremely strong, broadened spectral lines of the neutral alkali metals (the potassium doublet centered near 7682 Å and the sodium doublet at 5893 Å), we see photometric variations that differ strikingly from those of the 8000–10000 Å “red continuum” that dominates our detected flux. On UT 2014 February 24, these variations are anticorrelated with the red continuum, while on February 25 they have a large relative phase shift. The extent to which the wavelength-dependent photometric behavior diverges from that of the red continuum appears to correlate with the strength of the alkali absorption. We consider but ultimately reject models in which our observations are explained by lightning or auroral activity. A more likely cause is cloud-correlated, altitude-dependent variations in the gas-phase abundances of sodium and potassium, which are in chemical equilibrium with their chlorides in brown dwarf atmospheres. Clouds could influence these chemical equilibria by changing the atmospheric temperature profile and/or through cloud particles acting as chemical catalysts.
Identification of bacterial communities in extreme sites of Pakistan using high throughput barcoded amplicon sequencing

Published: October 2021

Microorganisms thrive nearly everywhere including extreme environments where few other forms of life can exist. Geochemistry of extreme sites plays a major role in shaping these microbial communities and microbes thriving in such harsh conditions are untapped sources of novel biomolecules. To understand the structure and composition of such microbial communities, culture-independent bacterial diversity was characterised for two extreme sites in Pakistan, Khewra salt range and Murtazaabad hot spring. Barcoded amplicon sequencing technique was used to study the microbial communities. Physicochemical analysis of these sites was also conducted to study the dynamics of microbial communities under stressed conditions. Metagenomic sequencing of salt range soil samples yielded of 40,433 16S rRNA sequences, while hot spring sediments produced 76,449 16S rRNA sequence reads. Proteobacteria were predominant in saline soil while Firmicutes were most abundant in hot spring sediment. The taxonomic analysis of saline samples revealed 914 operational taxonomic units (OTUs) while that of hot spring sequences were clustered into 726 distinct OTUs. OTUs from genus Alkalibacillus were most abundant in hot spring sediments, whereas Haloarcula were more prevalent in saline soil. Some unidentified sequences were also present at each taxonomic level. Multivariate analysis indicated that electrical conductivity and pH are the major environmental factors involved in modelling microbial communities. This study revealed a poly-extremophilic microbial community in the Murtazaabad hot spring and characterised the unexplored halophilic microbial diversity of saline soil of Pakistan.

Published: October 2021

Background/Aims: Relatively little data are available on how the response to the coronavirus disease 2019 (COVID-19) pandemic has affected treatment outcomes in patients receiving chemotherapy for lymphoma or multiple myeloma. We aimed to determine the effect of COVID-19 countermeasures on treatment outcomes in this patient population.Methods: We retrospectively analyzed data on patients treated for lymphoma or multiple myeloma in two tertiary hospitals in Seoul. Patients were divided into two groups: group 1 included patients who received chemotherapy between September and December 2019 (the control period), and group 2 included patients who received chemotherapy between September and December 2020 (the study period). Countermeasures to COVID-19 were applied to the patients in group 2. The countermeasures implemented included mask wearing and regular handwashing at home and in hospital; COVID-19 risk assessments on all hospital visitors; and pre-emptive COVID-19 screening for all newly hospitalized patients and their resident guardians.Results: No differences in treatment outcomes, including treatment response, incidence and duration of neutropenia or neutropenic fever, delays in chemotherapy, or number of deaths during chemotherapy, were observed between the g roups. None of the patients in group 2 tested positive for COVID-19, and there were no COVID-19-related deaths during the study period.Conclusions: Countermeasures to COVID-19 did not affect treatment outcomes in patients receiving chemotherapy for lymphoma or multiple myeloma. Data on the effect of countermeasures to COVID-19 on treatment outcomes should continue to be analyzed to ensure that treatment outcomes are not adversely affected.

Background/Aims: Cigarette smoking is an important modifiable risk factor in kidney disease progression. However, the underlying mechanisms for this are lacking. This study aimed to assess whether nicotine (NIC), a major toxic component of cigarette smoking, would exacerbates tacrolimus (TAC)-induced renal injury.Methods: Sprague-Dawley rats were treated daily with NIC, TAC, or both drugs for 4 weeks. The influence of NIC on TAC-caused renal injury was examined via renal function, histopathology, oxidative stress, mitochondria, endoplasmic reticulum (ER) stress, and programmed cell death (apoptosis and autophagy).Results: Both NIC and TAC significantly impaired renal function and histopathology, while combined NIC and TAC treatment aggravated these parameters beyond the effects of either alone. Increased oxidative stress, ER stress, mitochondrial dysfunction, proinf lammatory and profibrotic cytokine expressions, and programmed cell death from either NIC or TAC were also aggravated by the two combined.Conclusions: Our observations suggest that NIC exacerbates chronic TAC nephrotoxicity, implying that smoking cessation may be beneficial for transplant smokers taking TAC.
L’impact social : benign neglect ou face cachée de la finance entrepreneuriale ?
Authors: Benomar Julien , Chabaud Didier
Published: October 2021

Si le financement de l’aide internationale dépasse les 150 milliards de dollars annuellement, l’impact de celui-ci auprès des populations bénéficiaires reste incertain. En ce sens, l’étude de l’aide apportée à des institutions de microfinance suggère que la mise à disposition de subventions ne favorise pas nécessairement l’obtention d’une bonne performance. Cette étude de cas témoigne, à ce propos, que les évaluations de projets de développement apprécient principalement la réalisation opérationnelle et financière des activités programmées, sans prendre en compte l’impact de ces activités auprès des populations vulnérables. Si les préconisations de la Social Performance Task Force insistent sur la qualité de la gouvernance et sur la responsabilité sociale des Institutions de microfinance, elles ne conduisent pas à intégrer l’impact économique et social auprès des bénéficiaires, qui constitue ainsi la face cachée du financement de l’aide internationale.
Impact investing : la face cachée d’un discours “hybride” ?
Authors: Caseau Cornelia
Published: October 2021

Impact investing est un moyen de financement fondé sur trois objectifs : l’impact social, l’impact environnemental et le retour financier. Se pose dès lors la question : quel discours les impact investors avec leur business modèle hybride peuvent-ils adopter pour répondre à ces trois objectifs ? Cette étude s’intéressera spécifiquement au discours “hybride” mis en place sur les sites web, adressé (a priori) à un public d’investisseurs non-professionnels qui souhaiteraient placer des capitaux dans des organisations d’ impact investing , et cherchera à déterminer si ce discours, partagé entre engagements éthiques et financiers, entre contraintes de standardisation et réussite commerciale pourrait révéler une face cachée.
Dynamiques de proximité et politiques publiques territoriales : quels effets de la proximité d’opportunité ?
Authors: Arnaud Charlène , Anberrée Alice
Published: October 2021

Cette recherche vise, à partir de l’étude du cas d’un consortium de diffusion de la culture scientifique en Pays de la Loire, à déterminer si et comment l’activation intentionnelle d’une proximité d’opportunité, dans le cadre d’une politique publique territoriale, permet l’activation des autres formes de proximité géographiques et socio-économiques. En résulte un modèle théorique intégrateur des formes de proximités et des facteurs d’activation constitutifs d’une proximité territoriale impulsée par une proximité d’opportunité. Les résultats mettent ainsi en exergue a) les faiblesses du dispositif institutionnel étudié en ce qu’il permet uniquement une activation des proximités les plus formelles, b) que les facteurs d’activation restent des impensés de la politique publique et c) qu’une concurrence entre échelles de proximité nuit au projet territorial.
Anaphore associative et absence d’antécédent ou lorsqu’un conducteur roule en anaphore associative sans son véhicule
Authors: Salles Mathilde
Published: October 2021

Cet article est consacré à des anaphores associatives singulières, construites sans antécédent textuel explicite. Certaines d’entre elles manifestent encore un lien avec le contexte antécédent, alors que d’autres en sont totalement indépendantes. Ces dernières, plus contraintes que les premières, paraissent limitées à deux types d’anaphores associatives parmi les différents types identifiés par Kleiber : les anaphores associatives méronymiques (exemple : une voiture… les freins ) et les anaphores associatives fonctionnelles (exemple : une voiture… le conducteur ), qui ont pour caractéristique commune d’être construites avec un nom relationnel. L’étude de ces anaphores nous permettra de préciser certaines propriétés de l’anaphore associative en général, de souligner certaines différences entre les méronymes, les noms fonctionnels et les autres noms relationnels et de distinguer différents types d’emplois d’un nom comme conducteur .
Complexité sémantique et scénarios discursifs du repentir
Authors: Sorba Julie , Novakova Iva
Published: October 2021

Cet article en linguistique de corpus propose une étude de la complexité sémantique de quatre lexies d’affect ( repentir, repentance, se repentir, repenti ) dans un corpus journalistique. L’objectif de notre étude est double : d’une part, analyser la complexité sémantique des lexies du champ du repentir et étudier l’impact discursif de cette complexité sur leur environnement textuel et, d’autre part, distinguer en discours les substantifs repentir et repentance , que les outils lexicographiques présentent comme synonymes. Pour ce faire, nous adoptons une approche corpus-based qui nous permet d’élaborer, pour chaque lexie, son profil discursif à partir de nos observations et d’aborder le sens dans une dynamique discursive allant du syntagme à la phrase, de la phrase au paragraphe puis au texte.
La réalisation de l’excuse en moyen français : une recherche en pragmatique historique
Authors: Denoyelle Corinne
Published: October 2021

L’acte de langage de l’excuse semble moins fréquent au Moyen Âge qu’à notre époque. Le changement des réalisations de l’excuse ainsi que le changement des conditions pragmatiques de sa production témoignent d’une évolution d’une politesse positive à une politesse plus négative, et vers une société moins hiérarchisée, dans laquelle l’excuse peut désormais être réciproque et ne s’exerce plus uniquement de l’inférieur vers le supérieur. Trois réseaux lexicaux structurent la demande de pardon, à divers degrés d’intensité. Ils permettent de réaliser des actes de langage destinés à rétablir l’harmonie entre offenseur et offensé et leur récurrence signale leur dimension rituelle : (1) autour du verbe desplaire , c’est-à-dire « ne vous desplaise », ou plus rarement, chaloir, ennuyer ou courroucer , employés sous forme négative, qui visent à apaiser l’offensé ; (2) autour du verbe excuser relativement peu employé sous forme performative, mais qui entre dans des constructions formulaires du type « tenez moi ou ayez moi pour excusé » ; (3) autour du verbe pardonner , qui renvoie explicitement à une demande de pardon chrétienne. Ces verbes sont utilisés un peu différemment selon une gradation qui va de l’excuse la plus faible et la plus conventionnelle – verbe déplaire –  à l’excuse la plus forte, autour du verbe pardonner .
Sion et les diverses figures d’eschatologie
Authors: Krisel William , Krisel William
Published: October 2021

Le mot « Sion » est souvent traité comme synonyme de Jérusalem. Cependant, l’usage des deux vocables dans la Bible suggère qu’une distinction subtile devrait être faite entre les deux. Alors que Jérusalem est clairement un toponyme géographique, Sion se situe plutôt au croisement des axes espace-temps. La notion biblique de Sion est à la fois un moment dans le temps et un lieu dans l’espace. Cet article abordera en trois parties Sion et les diverses figures d’eschatologie que l’expression condense. Tout d’abord, les références bibliques à Sion seront brièvement examinées. Ensuite, la place de Sion dans le messianisme juif sera explorée. Troisièmement, nous présenterons la position des Églises protestantes qui épousent une théologie « sioniste chrétienne ». La conclusion portera sur les défis et les possibilités que la notion biblique de Sion offre pour l’approfondissement du dialogue œcuménique entre les Églises.
L’œuvre d’art et l’objet naturel. La problématique extension du concept d’objet esthétique chez Mikel Dufrenne
Authors: Bobant Charles
Published: October 2021

Dans ce texte, nous nous concentrons sur un article publié en 1955 dans lequel le philosophe Mikel Dufrenne modifie l’extension du concept d’objet d’esthétique afin d’englober à la fois l’œuvre d’art et l’objet naturel. Nous essayons de démontrer que ce changement affecte l’intention du concept d’objet esthétique qui, dans Phénoménologie de l’expérience esthétique (1953), renvoie exclusivement à l’œuvre d’art, en ce sens qu’un objet est « esthétique » quand il exprime l’attitude existentielle ou la qualité affective de l’artiste. Dorénavant, un objet est esthétique car il se donne comme « naturel », c’est-à-dire comme le produit spontané de sa source. À partir du moment où l’objet naturel devient un objet esthétique, la question se pose de savoir si Mikel Dufrenne ne transforme pas la Nature en Nature artiste. Nous tentons de mettre en évidence le fait que, dans son article, Mikel Dufrenne en vient à humaniser la nature, préparant ainsi le sol pour Le Poétique (1963), livre dans lequel il accomplira le geste solidaire, celui de naturaliser l’homme et l’artiste.
L’anthropologie morale comme lieu théologique. Un itinéraire de recherche à l’Institut Catholique de Paris
Authors: Bordeyne Philippe
Published: October 2021

Alors qu’il devient président de l’Institut pontifical de théologie Jean-Paul II pour les sciences du mariage et de la famille à Rome, l’auteur revient sur trente années de recherche à l’Institut Catholique de Paris, où il a exercé les charges de doyen de la Faculté de théologie, puis de recteur. Dans la ligne de sa thèse de doctorat sur l’angoisse dans Gaudium et spes , il montre que la vie concrète des hommes de ce temps est susceptible de nourrir une recherche pluridisciplinaire en théologie. La morale de la vie peut dès lors se fonder sur une théologie fondamentale du mariage et de la famille en relation avec l’amour, la génération et l’éducation, la santé, la maladie et la mort, la vie liturgique et son influence sur la vie morale. À la jonction de l’intime et du social, la famille permet de revisiter l’anthropologie morale et de renouveler l’approche de questions ecclésiologiques.

Les huit années du pontificat du pape François ont été marquées par une série de seuils qui sont repérables dans ses discours, dans sa pratique de gouvernement, dans son action pastorale. Le pape s’appuie sur la méthode du « voir-juger-agir » et sur la réception de la notion de pastoralité de la doctrine qui est essentielle à Vatican II. Dix enseignants-chercheurs du Theologicum rendent compte, du point de vue de leur spécialité, de certains aspects de ce pontificat, en soulignant l’importance de l’Écriture, la dynamique synodale à tous les niveaux de la vie de l’Église, ainsi que la recherche de la fraternité universelle, qui reconnaît l’histoire et la dignité de chacun. Pour l’enseignement de la théologie et pour la recherche, il convient alors de procéder par le dialogue et l’écoute, en réseau et de manière transdisciplinaire (cf. le préambule de Veritatis gaudium , n° 4).

Textile and clothing industry (T&C) is the second largest industry in the manufacturing sector. Currently, the industry operates on a linear model. Its value-chain is associated with several problems such as environment pollution (solid wastes, effluent discharges, air pollution, and emission of greenhouse gases), and resources extraction and depletion (raw materials, water, energy). These problems present the challenges that are addressed in this paper. These problems are further exacerbated by the rapid growth in population and attendant need for economic growth. There is therefore need to begin to address how to make the industry more sustainable. This will entail reviewing the entire T&C value chain from raw material extraction to post-consumption of its products. Nigeria, an emerging economy is used as a proxy for the study. The management of textile/clothing wastes in Nigeria does not follow best practices, as the wastes are generally, disposed at dumpsites. Even though Nigeria is rich in natural resources to produce textiles, the country largely depends on importation of finished T&C goods. This paper uses three models namely: new business model, efficient waste management system, and regenerative production processes and materials to demonstrate how the industry can become more sustainable. This effort will focus on reuse and recycling of textile and clothing products. Emphasis is built on eco-design to encourage proper waste management system to support recovery, reprocessing, reuse, and recycling of textile and clothing products.

A new kind of Bi-variate $ \lambda $ -Bernstein-Kantorovich type operator with shifted knots and its associated GBS form
Authors: Agrawal Purshottam Narain , Baxhaku Behar , Shukla Rahul
Published: October 2021

In this paper, we introduce a bi-variate case of a new kind of \begin{document}$ \lambda $\end{document}-Bernstein-Kantorovich type operator with shifted knots defined by Rahman et al. [31]. The rate of convergence of the bi-variate operators is obtained in terms of the complete and partial moduli of continuity. Next, we give an error estimate in the approximation of a function in the Lipschitz class and establish a Voronovskaja type theorem. Also, we define the associated GBS(Generalized Boolean Sum) operators and study the degree of approximation of Bögel continuous and Bögel differentiable functions by these operators with the aid of the mixed modulus of smoothness. Finally, we show the rate of convergence of the bi-variate operators and their GBS case for certain functions by illustrative graphics and tables using MATLAB algorithms.
Convergence of modified Szász-Mirakyan-Durrmeyer operators depending on certain parameters

Motivated by certain generalizations, in this paper we consider a new analogue of modified Szá sz-Mirakyan-Durrmeyer operators whose construction depends on a continuously differentiable, increasing and unbounded function \begin{document}$ \tau $\end{document} with extra parameters \begin{document}$ \mu $\end{document} and \begin{document}$ \lambda $\end{document}. Depending on the selection of \begin{document}$ \mu $\end{document} and \begin{document}$ \lambda $\end{document}, these operators are more flexible than the modified Szá sz-Mirakyan-Durrmeyer operators while retaining their approximation properties. For these operators we give weighted approximation, Voronovskaya type theorem and quantitative estimates for the local approximation.
The History of a Genuine Fake Philosophical Treatise (Ḥatatā Zar’a Yā‘eqob and Ḥatatā Walda Ḥeywat). Episode 1: The Time of Discovery. From Being Part of a Collection to Becoming a Scholarly Publication (1852-1904)
Authors: Wion Anaïs
Published: October 2021

In the middle of the nineteenth century, in the Ethiopian highlands, a Catholic missionary named Giusto d’Urbino chose to put an end to his evangelizing activities and resolved to devote himself fully to studying Ge’ez, Amharic, and Ethiopia’s Orthodox civilization. His mentor, Antoine d’Abbadie, was well-known at the time for his scholarly writings on Ethiopia. D’Urbino sent him the results of his work, in particular two copies of a very rare philosophical text, allegedly authored by an Ethiopian thinker in the seventeenth century. The present article is the first in a series devoted to the history and status of the Ḥatatā Zar’a Yā‘eqob and its appendix, the Ḥatatā Walda Ḥeywat. In order to show how these texts fit into Giusto d’Urbino’s oeuvre, this article draws on the manuscripts he sent to Antoine d’Abbadie, and analyzes the hitherto unpublished correspondence between the two men. As a linguist and translator, Giusto d’Urbino wanted to make a contribution to Ethiopian studies. His letters also suggest that he was an anxious and ambitious thinker, intent on producing a philosophical work. Might the two Ḥatatā have been a response to this twofold ambition?
Réinvestir dans les réseaux ferrés d’Île-de-France pour surmonter leurs défaillances : de l’échec technique à l’impensé politique
Authors: Baron Nacima , Khelladi Yassine
Published: October 2021

Cet article porte un regard critique sur un récit d’échec en s’appuyant sur plus d’une vingtaine de témoignages de professionnels engagés dans la gestion d’une des lignes les plus défaillantes de la région parisienne. Trois cadres d’analyse des politiques publiques (policy failure, policy learning, network governance) sont convoqués. Ils éclairent successivement : (1) l’incapacité des parties prenantes de s’accorder sur un type d’exploitation satisfaisant de cette ligne ; (2) la défiance constante entre parties prenantes et la course à l’expertise qu’elle entraîne ; (3) le refus d’arbitrer politiquement des choix de réallocation des moyens sur différentes sections de la ligne, donc différents territoires franciliens. En mettant à jour les désajustements entre information, expertise et procédures décisionnelles, les auteurs interprètent le blocage du processus de gouvernance partagée de la ligne comme le résultat d’un insurmontable statu quo. L’un des résultats de cette recherche est de démontrer que les partenaires savent et peuvent régénérer une infrastructure, mais qu’ils ne parviennent pas à en faire un projet territorial, c’est-à-dire à mettre en œuvre une vision politique de long terme dégagée des intérêts locaux.
Self-as-Subject for Doctoral Research
Authors: Throne Robin
Published: October 2021

This chapter presents reflections on the use of self-as-subject research within doctoral education as a pathway to explore meaning of study phenomena to uncover new knowledge from the individual of the self. Knowledge is contextual and discoverable from within this rich internal experience of the researcher-participant and extant and contemporary perspectives are presented to illustrate the importance and appropriateness of the selection of self-as-subject research methods including autoethnography and heuristic inquiry for doctoral-level research. The importance of the relational aspects of the doctoral researcher and doctoral research supervisor is briefly considered as well as contextual and institutional aspects necessary to inform doctoral researchers who may choose these methods of inquiry.
Integration in Mixed Methods Research Designs by Graduate Students at the University of Science and Technology
Authors: Pasipamire Notice
Published: October 2021

This chapter reports on a study that investigated how graduate students in the Faculty of Communication and Information Science at NUST were approaching integration in their mixed-methods research dissertations. There has been a concern that lack of expertise of what mixed-methods research is restricts the integrative capacity. Using a research synthesis method, the study investigated three graduate programmes, namely Master's degrees in Library and Information Science, Records and Archives Management, and Journalism and Media Studies from 2016 up to 2018. A total of 95 dissertations were reviewed, and 40 employed mixed-methods research design. It was discovered that integration was commonly done at methods and interpretation levels. Integration of qualitative and quantitative data sets resulted in confirmation (83), expanding understanding (27), and discordance (31). Graduate students dealt with discordant findings by either ignoring the discordance (20), seek corroboration with existing literature (7), or give priority to the quantitative strand (4).

In recent years, our society has experienced a major renaissance regarding cultural and personal beliefs, which has affected the overall environment and traditions within our current school settings, thus the need for integrating multicultural theoretical practices to ensure success for diverse populations within Pre-K-12 and postsecondary education. According to Guo and Jamal, there is a need for learning environments to embrace diversity and engage in the personification of respect for the views, beliefs, and values of students. This body of work is focused on the identification of barriers surrounding academic achievement for diverse learners in the Pre-K-12 and postsecondary settings and provides useful tools and strategies that educators may use to further support diverse learners.
Race for Social Justice in Higher Education
Authors: Patterson Bryan Q.
Published: October 2021

In the last decade, there has been a greater focus on social justice concerns in United States. These concerns include addressing situations of racism, microaggressions, and racial injustices. As a result of these concerns, the need for social justice has become more apparent for institutions of higher education to adjust and rethink how they become more inclusive and provide more equitable opportunities for all stakeholders. Institutions of higher education are being pushed into unfamiliar territory, and the role of academics and high education institutions will need to be redefined in a new model of true systematic change and policy overhaul. How do institutions of higher education (colleges and universities) become more accountable in reshaping their purpose and mission statements through the lens of social justice and inclusivity? This chapter will generate insights and illuminate ongoing institutional conversations regarding the successful adoption of social justice frameworks and practices in the foundations of higher education.
Structural Power, Systemic Poverty, and Entrenchment Among African American Males
Authors: Granderson Kevin
Published: October 2021

Poverty and structural power are immensely broad phenomena shaping economic and social architectures of societies globally. However, among the depth of complex mechanisms covertly functioning to perpetuate poverty, this chapter identifies structural power as one of the critical social constructs influencing systemic poverty. To explore structural power as a social force influencing systemic poverty, as a conceptual framework, and as means to support the overtone of social injustice, throughout this chapter an adaptation of the adverse childhood experiences (ACE) model is used. Through a more narrowed approach, the researcher uses the ACE model to explore structural power and systemic poverty through four experiential factors: educational, social, physical, and psychological. The experiences are motived by structural power and defined within the context of systemic poverty to explore the influence of those experiences on entrenchment of African American males later in adulthood.

An Emoji Is Worth a Thousand Words
Authors: Huang Yidan , Ma Jun , Wu Chia-Huei , Yang Shu
Published: October 2021

Face emojis are regularly used in reviews on online shopping sites to add richness and/or levity to the text. However, few researchers have investigated the use of face emojis in consumer reviews. This paper examined the effects of the number of face emojis (none, one, and three) in user-generated reviews (UGRs) on trustworthiness and purchase intention. They found that the number of face emojis in UGRs has a profound impact on consumers. A greater number of face emojis correlates with a greater degree of review trustworthiness. However, the effect of emojis on purchase intention changes depending on the situation. Additionally, when there is a profile picture, consumers pay more attention to it, and the positive effect due to face emojis disappears. Moreover, the gift giver-recipient relationship moderates the effect of face emojis on user decisions. The findings of our work have theoretical and managerial implications with respect to providing a new means of understanding consumer perceptions of products, from which business can benefit by improving sales and policies.
2D vs 3D morphological analysis of dorsal root ganglia in health and painful neuropathy
Authors: Carozzi Valentina Alda , Salio Chiara , Rodriguez-Menendez Virginia , Ciglieri Elisa , Ferrini Francesco
Published: October 2021

Dorsal root ganglia (DRGs) are clusters of sensory neurons that transmit the sensory information from the periphery to the central nervous system, and satellite glial cells (SGCs), their supporting trophic cells. Sensory neurons are pseudounipolar neurons with a heterogeneous neurochemistry reflecting their functional features. DRGs, not protected by the blood brain barrier, are vulnerable to stress and damage of different origin (i.e., toxic, mechanical, metabolic, genetic) that can involve sensory neurons, SGCs or, considering their intimate intercommunication, both cell populations. DRG damage, primary or secondary to nerve damage, produces a sensory peripheral neuropathy, characterized by neurophysiological abnormalities, numbness, paraesthesia and dysesthesia, tingling and burning sensations and neuropathic pain. DRG stress can be morphologically detected by light and electron microscope analysis with alterations in cell size (swelling/atrophy) and in different sub-cellular compartments (i.e., mitochondria, endoplasmic reticulum, and nucleus) of neurons and/or SGCs. In addition, neurochemical changes can be used to portray abnormalities of neurons and SGC. Conventional immunostaining, i.e., immunohistochemical detection of specific molecules in tissue slices can be employed to detect, localize and quantify particular markers of damage in neurons (i.e., nuclear expression ATF3) or SGCs (i.e., increased expression of GFAP), markers of apoptosis (i.e., caspases), markers of mitochondrial suffering and oxidative stress (i.e., 8-OHdG), markers of tissue inflammation (i.e., CD68 for macrophage infiltration), etc. However classical (2D) methods of immunostaining disrupt the overall organization of the DRG, thus resulting in the loss of some crucial information. Whole-mount (3D) methods have been recently developed to investigate DRG morphology and neurochemistry without tissue slicing, giving the opportunity to study the intimate relationship between SGCs and sensory neurons in health and disease. Here, we aim to compare classical (2D) vs whole-mount (3D) approaches to highlight “pros” and “cons” of the two methodologies when analysing neuropathy-induced alterations in DRGs.
