How good are my search strings? Reflections on using an existing review as a quasi-gold standard
Authors: Huynh Khanh Vi Tran  , Börstler Jürgen , bin Ali Nauman , Unterkalmsteiner Michael
Published: December 2021

Background: Systematic literature studies (SLS) have become a core research methodology in Evidence-based Software Engineering (EBSE). Search completeness, i.e., finding all relevant papers on the topic of interest, has been recognized as one of the most commonly discussed validity issues of SLSs.

Aim: This study aims at raising awareness on the issues related to search string construction and on search validation using a quasi-gold standard (QGS). Furthermore, we aim at providing guidelines for search string validation.

Method: We use a recently completed tertiary study as a case and complement our findings with the observations from other researchers studying and advancing EBSE.

Results: We found that the issue of assessing QGS quality has not seen much attention in the literature, and the validation of automated searches in SLSs could be improved. Hence, we propose to extend the current search validation approach by the additional analysis step of the automated search validation results and provide recommendations for the QGS construction.

Conclusion: In this paper, we report on new issues which could affect search completeness in SLSs. Furthermore, the proposed guideline and recommendations could help researchers implement a more reliable search strategy in their SLSs.
Unleashing the Potential of Crowd Work: The Need for a Post-Taylorism Crowdsourcing Model
Authors: Lykourentzou Ioanna , Robert Jr. Lionel P. , Barlatier Pierre-Jean
Published: December 2021

Paid crowdsourcing connects task requesters to a globalized, skilled workforce that is available 24/7. In doing so, this new labor model promises not only to complete work faster and more efficiently than any previous approach but also to harness the best of our collective capacities. Nevertheless, for almost a decade now, crowdsourcing has been limited to addressing rather straightforward and simple tasks. Large-scale innovation, creativity, and wicked problem-solving are still largely out of the crowd’s reach. In this opinion paper, we argue that existing crowdsourcing practices bear significant resemblance to the management paradigm of Taylorism. Although criticized and often abandoned by modern organizations, Taylorism principles are prevalent in many crowdsourcing platforms, which employ practices such as the forceful decomposition of all tasks regardless of their knowledge nature and the disallowing of worker interactions, which diminish worker motivation and performance. We argue that a shift toward post-Taylorism is necessary to enable the crowd address at scale the complex problems that form the backbone of today’s knowledge economy. Drawing from recent literature, we highlight four design rules that can help make this shift, namely, endorsing social crowd networks, encouraging teamwork, scaffolding ownership of one’s work within the crowd, and leveraging algorithm-guided worker self-coordination.
X-ray, IR and SEM studies on some Li-Cd ferrites
Authors:   Doodhsakhar Mahavidyalaya, Bidri, Kulkarni Sudhir
Published: December 2021

Lithium-Cadmium ferrites with general formula Li0.5-x/2 Fe2.5-x/2 Cdx O4 (with x = 0,0.1,0.2....,0.7) were prepared by standard ceramic method. X-ray diffraction studies confirms single phase formation and lattice parameters were calculated. The crystal structure is cubic and lattice parameter increases with increasing Cd content. The infrared absorption (IR) spectra of all the samples were recorded in the range 200-800 cm-1 at room temperature in the KBr medium. Lithium ferrite shows four principal bands and some shoulders have been observed. The force constants Kt and Ko were calculated using Waldron's analysis. Scanning electron microscopy studies shows increase in grain size up to x = 0.1 and then the grain size decreases with increase in cadmium content.
Short-Term Creep-Rupture Behaviour of AISI 310S Austenitic Stainless Steel Sheets Manufactured in Salem Steel Plant, a Special Steels Unit of Steel Authority of India Limited, Ministry of Steel, Government of India
Authors:   Professor, School of Freshman Engineering, Vel Tech Rangarajan Dr.Sagunthala R&D Institute of Science & Technology, Chennai, India, Kanni Raj A
Published: December 2021

The creep behavior of AISI 310S stainless steel taken from SAIL’s Salem stainless steel plant has been investigated by constant load tensile creep test at the temperatures of 973, 1023, and 1073 K and loads of 66.6, 74.8, 86.6, and 94.8 MPa. It exhibits steadystate creep behavior in most test conditions. The double logarithm plot of rupture life and applied stress yielded straight lines at all the three test temperatures indicating that power-law creep due to dislocation climb is the operating mechanism of creep deformation. Linear relationship was obtained for plots of logarithm of rupture life against inverse temperature obeying Arrhenius type of temperature dependence with activation energy of 340 kJ/mol. The stress-rupture data yielded a master curve of Larson-Miller parameter. The plot of Monkman-Grant relationship is typical indicating that rupture is controlled by growth of grain boundary cavities. The metallographic examination of crept samples revealed formation of grain boundary voids and cracks leading to intergranular creep fracture. Deformation twins and carbide precipitates were also observed. Creep-rupture properties are compared with that of AISI 600 ironbased superalloy to analyze quantitatively its behavior

PDHL-EDAS METHOD FOR MULTIPLE ATTRIBUTE GROUP DECISION MAKING AND ITS APPLICATION TO 3D PRINTER SELECTION
Authors: Lei Fan , Wei Guiwu , Shen Weijie , Guo Yanfeng
Published: December 2021

With the rapid development of 3D printing technology, 3D printers are manufactured based on the principle of 3D printing technology are more and more widely used in the manufacturing industry. Choosing high quality 3D printers for industrial production is of great significance to the economic growth of enterprises. In fact, it is difficult to select the most optimal 3D printers under a single and simple standard. Therefore, this paper establishes the probabilistic double hierarchy linguistic EDAS (PDHL-EDAS) method for the multiple attribute group decision making (MAGDM). Then the CRITIC model is introduced to derive objective weight and the cumulative prospect theory is leaded into obtain the cumulative weight of PDHLTS. In addition, what’s more, the PDHL-EDAS method is built and applied to the choice of high-quality 3D printer. Finally, compared with the available MAGDM methods under PDHLTS, the built method is proved to be scientific and effective.

Published: December 2021

Recent infrared interferometric observations revealed sub-parsec scale dust distributions around active galactic nuclei (AGNs). Using images of Clumpy torus models and NGC 1068 as an example, we demonstrate that the near- and mid-infrared nuclear emission of some nearby AGNs will be resolvable in direct imaging with the next generation of 30 m telescopes, potentially breaking degeneracies from previous studies that used integrated spectral energy distributions of unresolved AGN tori. To that effect we model wavelength-dependent point spread functions from the pupil images of various telescopes: James Webb Space Telescope, Keck, Giant Magellan Telescope, Thirty Meter Telescope, and Extremely Large Telescope. We take into account detector pixel scales and noise, and apply deconvolution techniques for image recovery. We also model 2D maps of the 10 μm silicate feature strength, S
10, of NGC 1068 and compare with observations. When the torus is resolved, we find S
10 variations across the image. However, to reproduce the S
10 measurements of an unresolved torus a dusty screen of A

V
> 9 mag is required. We also fit the first resolved image of the K-band emission in NGC 1068 recently published by the GRAVITY Collaboration, deriving likely model parameters of the underlying dust distribution. We find that both (1) an elongated structure suggestive of a highly inclined emission ring, and (2) a geometrically thin but optically thick flared disk where the emission arises from a narrow strip of hot cloud surface layers on the far inner side of the torus funnel, can explain the observations.
Thermal Instabilities and Shattering in the High-redshift WHIM: Convergence Criteria and Implications for Low-metallicity Strong H i Absorbers

Published: December 2021

Using a novel suite of cosmological simulations zooming in on a megaparsec-scale intergalactic sheet (pancake) at z ∼ (3–5), we conduct an in-depth study of the thermal properties and H i content of the warm-hot intergalactic medium (WHIM) at those redshifts. The simulations span nearly three orders of magnitude in gas cell mass, ∼(7.7 × 106–1.5 × 104)M
⊙, one of the highest-resolution simulations of such a large patch of the intergalactic medium (IGM) to date. At z ∼ 5, a strong accretion shock develops around the pancake. Gas in the postshock region proceeds to cool rapidly, triggering thermal instabilities and generating a multiphase medium. We find the mass, morphology, and distribution of H i in the WHIM to all be unconverged, even at our highest resolution. Interestingly, the lack of convergence is more severe for the less-dense, metal-poor intrapancake medium (IPM) in between filaments and far outside galaxies. With increased resolution, the IPM develops a shattered structure with most of the H i in kiloparsec-scale clouds. From our lowest-to-highest resolution, the covering fraction of metal-poor (Z < 10−3
Z
⊙) Lyman-limit systems (N
H I > 1017.2cm−2) in the z ∼ 4 IPM increases from ∼(3–15)%, while that of metal-poor damped Lyα absorbers (N
H I > 1020cm−2) increases from ∼(0.2–0.6)%, with no sign of convergence. We find that a necessary condition for the formation of a multiphase shattered structure is resolving the cooling length, l
cool = c
s
t
cool, at T ∼ 105 K. If this is unresolved, gas “piles up” at T ≲ 105 K and further cooling becomes very inefficient. We conclude that state-of-the-art cosmological simulations are still unable to resolve the multiphase structure of the WHIM, with potentially far-reaching implications.
Fermi-LAT Detection of Extended Gamma-Ray Emission in the Vicinity of SNR G045.7-00.4: Evidence of Escaping Cosmic Rays Interacting with the Surrounding Molecular Clouds
Authors: Zhang Hai-Ming , Liu Ruo-Yu , Su Yang , Zhu Hui , Xi Shao-Qiang , Wang Xiang-Yu
Published: December 2021

We present an analysis of Fermi Large Area Telescope data of the gamma-ray emission in the vicinity of a radio supernova remnant (SNR), G045.7-00.4. To study the origin of the gamma-ray emission, we also make use of the CO survey data of Milky Way Imaging Scroll Painting to study the massive molecular gas complex that surrounds the SNR. The whole size of the gigaelectronvolt emission is significantly larger than that of the radio morphology. Above 3 GeV, the gigaelectronvolt emission is resolved into two sources: one is spatially consistent with the position of the SNR with a size comparable to that of the radio emission, and the other is located outside of the western boundary of the SNR and spatially coincident with the densest region of the surrounding molecular cloud. We suggest that the gigaelectronvolt emission of the western source may arise from cosmic rays (CRs) that have escaped the SNR and illuminated the surrounding molecular cloud. We find that the gamma-ray spectra of the western source can be consistently explained by this scenario with a total energy of ∼1050 erg in escaping CRs assuming the escape is isotropic.

Published: December 2021

Background and aim of the study: Sclerostin is produced by osteocytes and has been shown to down-regulate the synthesis of many markers of bone formation by osteogenic cells. The aim of this study to investigate the relationship between serum sclerostin levels and bone mineral disorders and vascular calcification in hemodialysis patients (HD).
Methods:This is a cross-sectional study of 70 patients with ESRD on regular HD for at least six months, Theodor Bilharz Research Institute, Giza, Egypt.Twenty-five subjects who matched the ages, genders, and demographics of the study patients were included as a control group.All patients and control groups included in the study underwent a full through history and clinical examination. Serum calcium, phosphorus, alkaline phosphatase and intact PTH (iPTH) levels were measured. Serum sclerostin was measured by an ELISA. Bone Mineral Densitometry Measurements BMD (g/cm2) was determined by dual-energy X-ray absorptiometry (DXA). CT scan was done to detect the presence or absence of vascular calcification and transthoracic echocardiogram to detect the presence or absence of  valvular calcification.
Results:The mean seumscleostin levels was a statistically significant high in the HD patients when compared with the control group (156.8 ±121.4 Vs.29.38±0.84,  p =0.0001 ) and statistically significant high mean ALP in the HD patients when compared with the control group (147.2 ± 94.3      Vs.              38.8 ±23.4, p = 0.0001). The mean BMD  was statistically significant low in the HD patients when compared with the controls (0.839±0.086 g/ m2 Vs.1.306  ±0.153 g/ m2, p = 0.0001).The mean seumscleostin levels was statistically significant high in the HD patients with vascular and valvular  calcification  when compared with HD patients without calcification.Using spearman correlation coefficient analysis, there was  statistically significant negative correlations between serum sclerostin levels and iPTH(r=-0.362,   p =0.0021), ALP (r=-0.301, p =0.0114), and BMD (r=-0.469, p =0.0278 ), and there was a statistically significant positive correlation between serum sclerostin levels and phosphate(r=0.5829,  p =0.0001 ).Independent predictors of BMD in HD patients were determined using multi-variate regression analysis. Sclerostin levels, iPTH, ALP, and age  were found to be independent predictors of BMD.
Conclusion: High sclerostin levels in patients with ESRD on HD were associated with high risk of vascular and valvularcalcification and were independent predictors of low BMD in such population.
Réflexions cliniques et projectives du harcèlement à l’adolescence
Authors: Mazoyer Anne-Valérie , Ballet Véronique
Published: December 2021

Cet article propose une analyse des répercussions psychiques du harcèlement scolaire illustrée par la rencontre d’une adolescente. Nous posons l’hypothèse selon laquelle le traumatisme du harcèlement et le processus pubertaire réactivent le traumatisme primaire rendant ainsi l’adolescente plus vulnérable au harcèlement. À partir des projections fantasmatiques, sollicitées par un entretien clinique et l’épreuve projective du Rorschach, nous tentons d’analyser les assises narcissiques, les modes de relations objectales, la problématique œdipienne ainsi que la dépression liée à la perte d’objet et un défaut de symbolisation. Grâce à une réflexion praxéologique qui nous permet de discuter les aspects transféro-contre-transférentiels dans la clinique traumatique, nous proposons une perspective d’accompagnement par des entretiens cliniques et une médiation artistique.
Intégration des usagers et usagères et extractivisme des savoirs expérientiels : une critique ancrée dans le modèle écologique des savoirs dans le champ de la santé mentale
Authors: Godrie Baptiste
Published: December 2021

Cet article critique le modèle intégrationniste de participation des usagers et usagères dans les institutions sociosanitaires au Québec et en France, caractérisé par un rapport extractiviste aux savoirs issus du vécu de ces personnes ainsi que par une vision individualiste, dépolitisée et non conflictuelle de la participation. L’exemple des groupes d’entendeurs et entendeuses de voix suggère un autre rapport aux savoirs expérientiels, que le modèle de l’écologie des savoirs proposé par Boaventura de Sousa Santos permet de mieux comprendre. L’article s’appuie la littérature scientifique ainsi que sur des données empiriques issues des recherches réalisées par l’auteur depuis 2009 dans le champ de la santé mentale.
Decreased CSF1R Signaling and the Accumulation of Reticular Pseudo-Drusen?
Authors: Harford Deirdre A. , Delaney Conor , O'Callaghan Jeffrey , Hudson Natalie , Connolly Ruairi , Doyle Sarah , Farrell Michael , Doherty Colin P. , Cahill Mark , Campbell Matthew
Published: December 2021

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is caused by dominant-acting mutations in the gene colony-stimulating factor 1 receptor (
CSF1R
). It is an ultra-rare leukoencephalopathy that involves demyelination of white matter and early-onset dementia. It has been well validated that mutations in the kinase region of the gene cause decreased signaling of the receptor via its two cognate ligands interleukin-34 (IL-34) and colony-stimulating factor-1 (CSF-1). In this article, we report a thorough analysis of retinal integrity in a 48-year-old genetically diagnosed ALSP patient. We show that although the optic nerve, optic chiasm, and optic tracts are relatively preserved, the patient has visual field deficits likely due to optic radiation and/or cortical atrophy. Intriguingly, we report the appearance of inner retinal vascular leakage and the appearance of reticular pseudo-drusen (RPD)-like deposits. We propose that the early stages of RPD accumulation may be associated with an attenuated CSF-1 receptor signaling axis.

Bi-shifting semantic auto-encoder for zero-shot learning
Authors: Wang Yu
Published: December 2021

Zero-shot learning aims to transfer the model of labeled seen classes in the source domain to the disjoint unseen classes without annotations in the target domain. Most existing approaches generally consider directly adopting the visual-semantic projection function learned in the source domain to the target domain without adaptation. However, due to the distribution discrepancy between the two domains, it remains challenging in dealing with the projection domain shift problem. In this work, we formulate a novel bi-shifting semantic auto-encoder to learn the semantic representations of the target instances and reinforce the generalization ability of the projection function. The encoder aims at mapping the visual features into the semantic space by leveraging the visual features of target instances and is guided by the semantic prototypes of seen classes. While two decoders manage to respectively reconstruct the original visual features in the source and target domains. Thus, our model can capture the generalized semantic characteristics related with the seen and unseen classes to alleviate the projection function problem. Furthermore, we develop an efficient algorithm by the advantage of the linear projection functions. Extensive experiments on the five benchmark datasets demonstrate the competitive performance of our proposed model.
Development of compressive testing device for glass fiber based single face corrugated structure sheet, and estimation of buckling strength of straight panel of that structure sheet

This work aims to reveal the in-plane-compressive characteristics of Glass Fibre based single face corrugated Structure Sheet (GFSS) by developing a loading holder of the both ends of the panel of GFSS in the direction of the cross machine direction. A grooved end-support device was developed and exmined. In order to set stably and quickly a straight panel of GFSS on the compressive-testing apparatus, the width and the depth of the holder's groove were varied against the geometrical size of the panel, and the stability and reproducibility of compressive deformation of the panel was experimentally investigated. When changing the height of the panel and reinforcing the both ends of the panel by dipping instant adhesives, the deformation behavior and the buckling strength was characterized in three modes: a short height crushing without lateral deflection, a small lateral deflection mode as the intermediate state, and a triangle-like folding as a long height crushing.
Bifurcation analysis and optimal control of SEIR epidemic model with saturated treatment function on the network
Authors: Xie Boli ,   School of Science, North University of China, Taiyuan 030051, China, Liu Maoxing , Zhang Lei
Published: December 2021

In order to study the impact of limited medical resources and population heterogeneity on disease transmission, a SEIR model based on a complex network with saturation processing function is proposed. This paper first proved that a backward bifurcation occurs under certain conditions, which means that $ R_{0} < 1 $ is not enough to eradicate this disease from the population. However, if the direction is positive, we find that within a certain parameter range, there may be multiple equilibrium points near $ R_{0} = 1 $. Secondly, the influence of population heterogeneity on virus transmission is analyzed, and the optimal control theory is used to further study the time-varying control of the disease. Finally, numerical simulations verify the stability of the system and the effectiveness of the optimal control strategy.

Deux fragments d’une plaque de marbre, restés inédits, appartiennent à un album gravé en 192 par une association de bateliers d’Ostie. Le document présentait l’ordo corporatorum lenunculariorum pleromariorum auxiliariorum Ostiensium et incite donc à examiner l’emploi que les associations de métier faisaient de la notion d’ordo. Elle s’appliquait le plus souvent à l’ensemble de la communauté et non à son élite dirigeante. Un ordo collegii ne correspondait tout à fait ni au collège lui-même, ni à l’assemblée du collège, mais à la synthèse des deux : le collège solennellement réuni, selon son organisation formelle et hiérarchique, de manière à pouvoir prendre des décisions légitimes.

In questo contributo si rende nota l’iscrizione, proponendo un’integrazione delle lacune del testo e inquadrando il documento epigrafico nel più ampio contesto della storia della famiglia tra la fine del I e i primi decenni del II sec. d. C.
Silla a Ostia
Authors: Coarelli Filippo
Published: December 2021

Nel santuario di via della Foce a Ostia sono state scoperte tre basi iscritte relative a statue di scultori greci. Molto probabilmente facevano parte del bottino di un generale romano. La statua di Platone, autore della «Commedia Antica», opera di Lysikles e quella del filosofo Antistenes, opera di Phyromachos, provengono probabilmente da Atene, mentre quella della Pizia Charite, opera di Phradmon di Argo, proviene da Delfi. Date le provenienze e la datazione delle basi (i primi decenni del I secolo a.C.), non c’è dubbio che le statue siano state dedicate da Silla, unico possibile autore del saccheggio sia di Atene che di Delfi. Altri due oggetti provenienti dal santuario di Ostia portano alla stessa conclusione. In primo luogo, una lastra, parte di un grande basamento che potrebbe aver sostenuto la statua del dittatore, dove sono rappresentate in rilievo le figure di Teseo e Demetra, anch’esse allusive ad Atene. In secondo luogo, il rilievo dell’aruspice C. Fuluius Saluis, che raffigura la consultazione delle sortes nel santuario di Ercole a Ostia prima di partire per la guerra, forse le guerre di Silla in Oriente. In questo caso Silla sarebbe stato rappresentato nella parte sinistra del rilievo, ora mancante, al momento del sacrificio di ringraziamento al dio.
Il Tempio Rotondo a Ostia
Authors: Pensabene Patrizio
Published: December 2021

In questo articolo consideriamo il Tempio Rotondo sotto due aspetti che evidenzierebbero il suo carattere ibrido. Il primo aspetto è quello di luogo di culto imperiale della nuova dinastia severiana che è messa in relazione con i predecessori; il secondo, che presentiamo in via ipotetica, è quello di luogo di culto delle divinità orientali Sol e Magna Mater. In particolare, la grande corte rettangolare antistante alla cella richiama tradizioni architettoniche orientali. La cupola visibile parzialmente al di sopra del pronao supera il modello e le suggestioni derivate dal Pantheon. Essa richiama altre rotonde, quali l’Asklepieion di Pergamo o il «Tempio di Venere» a Baalbek, dove già osserviamo la completa autonomia della pianta centrale. Il tempio a nostro parere rifletterebbe una tendenza eclettica che segna il regno di Eliogabalo, che ne ha iniziato la costruzione. Vediamo una manifestazione di tale tendenza anche nel Tempio del Sole sul Palatino. In questo edificio l’imperatore aveva fatto radunare non solo la pietra nera di Emesa, ma anche quella di Cibele del tempio palatino della Magna Mater, e altri importanti segni legati alle origini di Roma. Riteniamo possibile che anche nel Tempio Rotondo la colonia ostiense abbia riposto importanti significati e messaggi.
Le iscrizioni delle Terme di porta Marina rinvenute da Gavin Hamilton
Authors: Turci Marcello
Published: December 2021

L’applicazione del metodo combinatorio (ricerca sui manoscritti di G. Marini e di E.Q. Visconti, rilievo fotogrammetrico delle epigrafi, analisi tecnica dell’impianto termale, revisione dei vecchi scavi e dell’ampia bibliografia sull’argomento) offre nuovi dati per la contestualizzazione di CIL XIV, 98 e CIL XIV, 137. Lo studio delle fasi architettoniche dell’edificio e dei manoscritti di Visconti conservato alla Bibliothèque Nationale de France ha consentito di ricondurre CIL XIV, 98 alla fase di impianto delle Terme di Porta Marina (iniziate da Adriano e terminate da Antonino Pio nel 139 d.C.). Per quanto riguarda la seconda epigrafe, conservata presso i Musei Capitolini, l’individuazione di due frammenti inediti conservati nei depositi del Parco Archeologico di Ostia, ha permesso di completarne il testo e di proporne l’attribuzione alla grande piscina absidata del frigidarium del terme.

Fêtes de commémoration annuelle et rituels funéraires à Philippes, colonie romaine en Macédoine orientale
Authors: Rizakis Athanasios D.
Published: December 2021

Philippes est la seule colonie romaine dans l’Orient à offrir un nombre appréciable de textes attestant les Parentalia et les Rosalia, fêtes romaines pour la commémoration des défunts. Cependant, le rituel suivi à Philippes, en particulier pour les Rosalia (décoration des tombes avec des roses, sacrifices de petits animaux, banquets à côté de la tombe) suit des traditions locales ou inspirées par l’Asie Mineure. Ce qui est très intéressant est que ces fêtes romaines furent adoptées par des Thraces au statut pérégrin (incolae), et non par des Grecs ou des Romains. L’appropriation de ces fêtes peut être expliquée à la fois par la « romanisation » de ces tribus thraces et par leur forte et ancienne relation avec Dionysos ou Héros cavalier et le culte des morts. Philippes apparaît ainsi comme ayant été un extraordinaire laboratoire ou des éléments hétérogènes de l’Orient et de l’Occident se sont mariés au point de se fondre complètement ensemble et de compliquer nos efforts pour chercher, à l’issue d’un long processus, les modèles initiaux ou les modalités de cette évolution.

Ritrovamenti scultorei dall’area sacra del Tempio di Ercole
Authors: Valeri Claudia
Published: December 2021

Il ritrovamento del tempio di Ercole fu la prima grande novità degli scavi condotti da Guido Calza in vista dell’Esposizione Universale del 1942. Ripercorrendo le indagini di quegli anni, e successivi, che interessarono tutta l’area sacra con i limitrofi edifici, sono presi in esame i materiali scultorei lì ritrovati tentando di definire meglio le possibili originarie collocazioni. In particolare si presenta il rilievo c.d. di Teseo e Arianna che, ritrovato nei pressi delle gradinate del tempio di Ercole, non ha finora avuto una vera edizione. In questa sede si propone una nuova interpretazione della scena raffigurata che rimanderebbe all’impresa di Ercole disceso negli Inferi per liberare Teseo e Piritoo.
La culla in una tomba
Authors: Settis Salvatore
Published: December 2021

I numerosi sarcofagi romani reimpiegati nel medioevo possono valere come una sorta di fossile-guida rivelatore sia del rapporto fra la cultura medievale e l’antichità classica, sia delle strategie di ricerca moderne e contemporanee sul ruolo della tradizione classica nella cultura medioevale. Pisa emerge per il numero, la qualità e la documentazione dei reimpieghi dei sarcofagi, ed è a partire da Pisa che si può ricostruire una storia comprensiva del tema, anche in un suo risvolto importante: l’influsso della scultura romana, attraverso i sarcofagi riusati, su artisti come Nicola Pisano. Questo testo esplora la natura intertestuale delle presenze di arte classica nei contesti medioevali; la diffusione e la natura del reimpiego anche per imperatori e pontefici (da Aquisgrana a Roma a Palermo); le modalità di repêchage di formule di pathos nei sarcofagi da parte di artisti medievali; i processi di riattivazione delle antiche formule attraverso il linguaggio gestuale; infine, il rapporto bi-univoco, testuale e figurativo, fra le Pathosformeln di Aby Warburg e i topoi della retorica antica rilanciati da Ernst Robert Curtius.
Jesus Christ, Heavenly Bodies, and Catholic Imaginations
Authors: Brown Elizabeth A.R.
Published: December 2021

The exhibition Heavenly Bodies: Fashion and the Catholic Imagination was on display at the Metropolitan Museum in New York and the Cloisters from 10 May to 8 October 2018. Some 200 garments and ornaments dating from the nineteenth through the twenty-first century were shown, as were some 40 (from the nineteenth and twentieth centuries) from the Vatican. The material from the Vatican was installed apart in the Met’s Anna Wintour Costume Center. The other items were displayed in the Medieval galleries in the Met and in the Cloisters, many in close proximity to medieval works of art. In this paper I discuss the rationales the curators and administrators of the Met and the Vatican proposed for mounting the exhibition and their descriptions of the purposes it aimed to serve, particularly important given the exhibit’s timing, a moment of grave crisis in the Church, which had commenced long before the show opened but accelerated sharply while it was on view. I then discuss the range of reactions to the exhibit and Gala. Finally, I comment on two broader themes. First, the place of wealth and display in the Catholic Church and particularly the Church’s adoption of material tokens of secular power and magnificence. Second, the relationship between the fashions exhibited in New York, papal and secular, on the one hand, and, on the other, a hypothetical Catholic imagination (or imaginations), as well as the varied motivations that may lead designers and artists to appropriate religious symbols, images, and stories for their own secular purposes.
Os sentidos sobre as mulheres no discurso da revista Claudia ao longo de uma década (2009-2019)
Authors: Bertasso Daiane , Rosa Amanda Regina
Published: December 2021

O objetivo geral da pesquisa é analisar quais sentidos sobre as mulheres são produzidos no discurso jornalístico da revista Claudia ao longo da última década, entre 2009 e 2019. Para isso, são analisadas capas e reportagens de capa de 12 edições publicadas nesse período, buscando-se mapear as marcas discursivas que constituem sentidos sobre as mulheres e identificar se há reprodução de estereótipos sobre o gênero feminino. Por meio da metodologia de Análise do Discurso francesa, foram identificadas sete formações discursivas que envolvem o reforço da beleza, do consumo, do profissionalismo, da capacidade multitarefa, da maternidade, do casamento e do poder enquanto atributos relacionados às mulheres. Em tais núcleos de sentidos, entre 2009 e 2019, foi possível notar uma modificação no discurso da revista, com a diminuição da reprodução de estereótipos e o fortalecimento das mulheres enquanto batalhadoras. Contudo, os sentidos permanecem legitimando determinadas atribuições tradicionalmente associadas ao gênero feminino, reiterando um ideal do que é “ser mulher”.

Identifying Common Student Experiences That Affect Success in a Crisis Context (COVID-19)
Authors: Saavedra Emily , Sanders Leonard
Published: December 2021

Learning experiences and educational opportunities around the world have been disrupted due to the outbreak of COVID-19. This chapter outlines a case study involving foundation-level students enrolled at an urban university in Aotearoa New Zealand. The case study is designed to gain a deeper understanding of student experiences during this time of crisis. Student narratives are analysed to identify common experiences and gain a clearer understanding of the self-reported factors that students identified as affecting their success, allowing academic and support staff to improve the pre-degree experience for foundation students. Affordable access to connectivity, increased pastoral care, and a digitally responsive curriculum were identified as key considerations to addressing inequities present in a crisis context (COVID-19) within the educational context and wider community.
A non-local inverse problem with boundary response
Authors: Ghosh Tuhin
Published: December 2021

The problem of interest in this article is to study the (non-local) inverse problem of recovering a potential based on the boundary measurement associated with the fractional Schrödinger equation. Let

0<a<1

, and let

u

solve

\begin{cases} ((-\Delta)^a + q )u = 0 &\operatorname{in} \Omega,\\ \operatorname{supp}\, u\subseteq \overline{\Omega}\cup \overline{W} ,\\ \overline{W} \cap \overline{\Omega}=\emptyset. \end{cases}

We show that, by making an exterior to boundary measurement as

\big(u|_{W}, \frac{u(x)}{d(x)^a}\big|_{\Sigma}\big)

, it is possible to determine

q

uniquely in

\Omega

, where

\Sigma\subseteq\partial\Omega

is a non-empty open subset and

d(x)=d(x,\partial\Omega)

denotes the boundary distance function.

We also discuss a local characterization of large

a

-harmonic functions in a ball or in the half space and its applications, which include boundary unique continuation and a local density result.
Leisure Cycling Entrepreneurialism in Johannesburg, South Africa
Authors: McKay Tracey , Coumbias Manoli , Kotze Nico
Published: December 2021

It is estimated that by 2050 as many as five billion bicycles could be in use globally. Reasons for this growth vary, with utility cycling strong in Europe and Asia; while in the United States of America, Canada, the United Kingdom, Australia and New Zealand cycling is a sport and leisure activity, with cycling deemed the ‘new golf’. Within this context, there is a rise in community or local bike shops (or LBS) which sell bicycles, related equipment and services. This qualitative study explored LBSs in greater Johannesburg, focusing on who the entrepreneurs are, how they service their clients, and what links the sector has to serious leisure. It was found that the owners demonstrated high levels of serious leisure cycling engagement and passion for the sport. A sense of being part of a bigger cycling community strongly influenced their entrepreneurial practices. This included how they ran their businesses, the employees they hired, as well as how they viewed cycling in general. The research also yielded insights into operational and sectoral realities, trends and challenges. Generally, it was found that the local bike shops in greater Johannesburg are key players in the supply, growth and development of sport and leisure cycling, thereby making a positive contribution to the cycling community. This is important in the light of the COVID-19 challenges experienced by the sport and leisure sector, as a loss of these shops will likely have a negative impact on cycling in Johannesburg.
Guest Houses, Drought and Water Management Strategies in the Cape Winelands, South Africa
Authors: Visser Gustav , Cloete Jamie
Published: December 2021

Tourism is a dynamic system essentially connected to all aspects of human and natural environments. Among these tourism systems and products, providers of tourist accommodation stand out. Within this context, water provision is crucial for tourist accommodation. Unfortunately, climate variability, and therefore, water availability, can and does impact tourism systems and tourism products, perhaps disproportionately so. In South Africa generally, and in an established tourism destination region such as the Cape Winelands in particular, guest houses are key role-players in the tourist industry. Nonetheless, from 2015 to 2018, this destination region experienced a crippling long-lasting drought, leading to fears of an imminent “Day Zero” – a point at which taps run dry. This would have been calamitous for tourism. To avert this, various water management strategies were implemented by Stellenbosch guest houses – the focal point of the Cape Winelands tourism region – to cope with and adapt to the drought. This study sought to examine the water management strategies manifested in the study region. It is concluded that various strategies were followed, and some appear to be permanent, rather than once-off responses. While these strategies might lead to more responsible water management strategies in tourist accommodation going forward, it appears that adopting sustainable water use practices was only done under duress and serious resistance from some guests resulted. It may be that water supply augmentation is the only way to preserve the tourism industry.

Published: December 2021

Modeling is the core of food processing supported by many approaches and governed by heat, mass, and momentum transfer equations. The objective of this paper is to mainly discuss and introduce mathematical modeling of some food processes. Food processing is unique from other material processing, as it includes complex multiphase transport and change in material properties during processing. It poses a great challenge in food process engineering. Now a day’s, consumers are taking more precautions before eating something. The way of food processing effectively impacts food quality. Most of the conventional industries use thermal processes like pasteurization, sterilization, and freezing. In recent years the main aim has been to improve these conventional processing technologies. Characterization of temperature distribution is done by mathematical modeling during processing, so this review paper aims to introduce mathematical modeling as a potential tool for the food processing industry. The mathematical models discussed in this article captures the essential features of a complex object or process based on a theoretical understanding of the phenomena and available measurements.

Industrial sector is a backbone of the economy throughout the world. Despite that there are a lot of benefits; such as development of urbanization, major contributor in economy’s growth is sign of industrial development. There are a lot of adverse effects on environment including depletion and damage of our natural and precious resources. Textile, cement, paper and pulp, sugarcane, food, pharmaceuticals, chemical, paint and other industries are largest consumers of the freshwater; for meeting the requirements of industrial production requirement for the industrial sector for their production. As a result the discharged huge amount of water in form of highly polluted water, this is a great threat to our ecosystem. The unplanned industrialization is a prime responsible for degradation of environment. If industrial wastewater is not properly treated instantly, it may create foulest and septic conditions in adjacent parts of the industrial areas. The discharges acute poisonous wastewater by different industries is responsible for reduction of penetration in crops, and severely affects aquatic life. There are many treatment techniques such as coagulation, adsorption, membrane, biological etc. by different research studies disclosed that coagulation with different chemicals alum, ferric chloride, lime, PACl, PVA and ferrous sulphate are very effective for remove of pollution. The industrial wastewater creates several problems such as health problems, aquatic life including water pollution. In this paper reviews the chemical coagulation treatment technologies for industrial wastewater.
