Authors: Madugba Joseph U. , Ben-Caleb E. , Lawal Adedoyin I. , Agburuga Uche T.
Published: May 2020

In this paper has been investigated tax savings behaviour of firms in Nigeria with the objective of finding out how it affects firm size. The ex-post facto research design was employed, and secondary data obtained from the annual reports of firms listed on the Nigeria Stock Exchange was used. Descriptive statistics and panel data regression tests were conducted. The data were further subjected to unit root test to establish the stationarity of the data. The result revealed that interest tax savings behaviour and depreciation savings behaviour have negative but significant relationship with firm size while effective tax rate has negative and insignificant relationship with firm size. The study concluded that the lower the firm size the higher the tax savings behaviour and vice versa of quoted companies in Nigeria. The paper recommended that tax regulatory authorities should focus their searchlight on tax aggressiveness of small sized companies as a strategy to reduce tax evasion while encouraging appropriate tax savings strategies to ensure tax compliance.
Albanian Aorist and Time Reference Points
Authors: Reçica Muhamet , Pajaziti Naser
Published: May 2020

Topics related to the structure of the temporal system of Albanian language always give opportunities for new discussions to deal with certain aspects related to various forms of this system, and one of them is the aorist, as a tense containing many semantic, temporal, aspectual, stylistic values, etc. The relationships that exist between the verbal tenses in this system within the absolute time-relative time dimension, which relate to the independent or dependent use of temporal forms against one another in different discoursing contexts, make up an interpretation-based approach to interest. Hence, the essential objective of this paper will be specifically the relations of the Albanian aorist to the other verbal forms, always observed with a time reference point, to illuminate the character of these purely temporal relations against each other under all circumstances of the actions that take place and are displayed by verbal forms in different contexts, relying on the corpus of examined materials.
Dynamics of Resilience on Women as Intimate Partner Violence Survivors
Authors: Nasution Sri Mulyani , Sutatminingsih Raras , Marhamah Marhamah
Published: May 2020

Women become weak and hopeless when suffering as a victim of Intimate Partner Violence. They experience multiple adversities and conduct searches and struggles to be able to survive and escape from these adversities. Previous research has focused more on efforts to find things that involve domestic violence; however, this research focuses more on finding solutions for women as victims of Intimate Partner Violence. Research has been conducted with qualitative methods that aim to explore the dynamic of resilience on a woman who survives from Intimate Partner Violence. Research’s questions are being compiled based on the understandings about the personal construct and the process of resilience that involved the violence she suffered, thinking style, seven factors of abilities on resiliency, social support, and how the participant’s current life is decided as the main theme of the research (Theme Category) which will be divided into several detailed themes. General results of the research are as follows: (1) Participants experience three types of violence (2) Victims' rejection of violence based on their thinking style which means violence should not be tolerated. (3) Social support greatly influences the victim's ability to survive (4) Initially, participants did not get adequate social support which caused the victim's inability to rise again. When participants begin to receive social support, they continue to try to get out of violence. (5) Several active strategies to control or stop violence can be found in the results of the analysis of research data. (6) Inner strength comes from the behavior of faith in God and identity as a mother. (7) Positive results obtained in this life. Ultimately, these themes will contribute to the resilience model of Intimate Partner Violence. Research conclusions will be discussed based on relevant theory.

Authors: Rochmiyati Siti , Ghozali Imam , Tiasari Luky
Published: May 2020

The purpose of this study was to identify the folklores carrying character values as teaching materials in English acquisition in Indonesia. This exploratory study was conducted in Central Java and Yogyakarta provinces, Indonesia by inviting 139 participants of Junior high school teachers, students, and experts. The data was collected through interview, documentation and observation, and analyzed descriptively using the  Miles, Huberman, & Saldaña' scheme, namely data collection, data condensation, data presentation and conclusion (2014). The result obtained 208 folklores categorized as fairytale, legend, and myth. By applying the Processability Theory (Pienemann, 2005), the researchers proposed some ideas in using the folklores which carry character values for supporting the English acquisition among junior high school students in Indonesia. Through an English integrated teaching and learning process, the students not only learnt the moral values from the folklores but also studied and acquired English as their foreign language. The students, who have been familiar with folklores from their hometown, possessed confidence in understanding the main idea of the story though it was written or told in English. They mostly learnt as well as acquired phrasal and lexical morphology of English.

ABSTRACT

The elderly are prone to experience increased cholesterol levels due to consumption of foods that are high in saturated fat, lack of exercise / activity, and aging. The purpose of this study was to analyze the differences in the effectiveness of Falun dafa cultivation practice (LKFD) and consumption of ginger (KWJ) in reducing cholesterol levels in the elderly. The research design is a comparative study. The population is all elderly in the Ngagel Rejo and Pacarkeling communities, Surabaya. The sample was selected by nonprobability sampling, a large sample of 35 people divided into 2 groups. The independent variable is LKFD and KWJ while the dependent variable is the total cholesterol level. The instrument consisted of a cholesterol meter and an observation sheet. Data analysis using Independent T Test (α <0.05). There was a significant decrease in total cholesterol levels between the LKFD and KWJ groups (t = 5.643; p = 0.000). LKFD can reduce total cholesterol more than KWJ. There was a significant difference in the reduction in total cholesterol levels between LKFD and KWJ interventions. In the elderly in the community, LKFD has proven to be more effective in reducing total cholesterol levels compared to KWJ.

Thesis is the final project that must be done by students to get a bachelor's degree. Timeliness of completing a thesis is important for undergraduate nursing students because after getting a bachelor's degree, they must proceed to professional education to get a professional nurses degree. The factors that support students completing their thesis on time are family support and self motivation. The purpose of this study was to determine the relationship of family support with motivation and timeliness of completing a thesis. The research design used is a correlation study with a retrospective approach. The population was all final-year students of the Nursing Study Program at Stikes Karya Husada Kediri with 96 people with a total population sampling technique. Data were collected through a questionnaire and then analyzed using the Spearman Rho test to determine the relationship of family support with student motivation and the Kendall Tau-b test to determine the relationship of family support with the timeliness of completing a thesis. Spearman Rho statistical test results showed p = 0.015 which showed a relationship of family support to motivation to complete student thesis with a correlation coefficient r = 0.249 indicating a positive relationship with the level of influence is not too large. While the Kendall Tau-b test results showed a value of p = 0.138 which means there is no relationship between family support with the timeliness of completing the thesis. Family support can increase student motivation in doing thesis, but apparently family support factors are not proven to significantly affect the timeliness of completing a thesis, this is because there are several other factors that can affect student motivation and timeliness of completing a thesis such as support from friends, facilities and infrastructure that support and factors from the supervisor.

Global system: situation, contemporary tendencies and possible perspectives of the power potential distribution
Authors: Hampl Martin
Published: May 2020

This contribution deals with the set-up of global power differentiation and its contemporary and prospective changes. Primary attention is paid to construction of representative aggregate indicators of power potential on the level of states and of sub-global systems. Into account is taken their territorial, population and economic size and that in a differentiated way (different weights attributed to partial size characteristics). The results confirm the anticipated asymmetry in the distribution of power potential and its shifting among superpowers. Especially emphasized is not only the current distribution of power among states, but above all among supranational systems – including the distinct potential in possibilities of further expansion and integration of sub-global systems.
Are research, development and innovations key processes of uneven regional development?
Authors: Žížalová Pavla , Csank Pavel
Published: May 2020

Research, development and innovations (R&D&I) are widely considered as key factors enhancing economic development of both nations and regions. R&D&I activities are, however, strongly concentrated in few areas. Therefore, one might consider disparities in R&D potential and its exploitation as a crucial source of regional disparities. Nevertheless, analysing spatial patterns of R&D&I activities brings several obstacles. These consist particularly in limited data available for description of processes linked to the translation of R&D&I activities into economic growth. This paper intends to search for suitable data and indicators analysing microdata from statistical survey on R&D and for more accurate usage for them as their most often aggregate use might lead to inaccurate or misleading conclusions.

Films and Audiovisual Potentiality in Tourism Destination Promotion: A European Perspective
Authors: Di Cesare Francesco , La Salandra Anthony A. , Craparotta Elena
Published: May 2020

The audiovisual medium represents a tool that is able to influence the perception and the decision-making process of a large potential tourist demand. This can be commonly observed but is also confirmed, year by year, by a wide variety of empirical research studies worldwide. In some
of them it emerged that the mere portrayal of a destination in an audiovisual production is not enough to reap the benefits of film-induced tourism. Tourism destinations need to work proactively to orient this phenomenon and to promote their territory and resources, among a whole and articulated
destination strategy. In recent years, several tourism organizations worldwide recognized the opportunities associated with film tourism, but the lack of a clear strategy allowing the destination to benefit from such opportunities has often resulted in missing good chances. It is still unclear
how much tourism development managers believe in the potential of audiovisual productions as a tool to be included in their destination management and marketing strategy. Furthermore, it is not clear whether such destination managers consider audiovisual and film productions among their tourism
promotion tools at all. This article's aim is to shed light on this situation. In order to understand what is, or is not, happening, a significant and heterogeneous panel of 30 European tourism destinations has been surveyed with a quantitative research approach through a questionnaire-based
web survey. It emerged that, as indicated by 100% of the respondents, European destination managers are aware of the relationship between film and tourism and mostly keen to work on it. But it is also possible to notice—among the results—that it seems movie-induced tourism is used
just through sporadic attempts and therefore not approached in a strategic way. The survey explores both existing attitudes towards the phenomenon, and the commitment to develop it, using film in tourism communication strategies. The results of this article provide a new foundation for further
research, as well as operative suggestions for worldwide tourism professionals committed to tourism development.

Published: May 2020

Let $K$ be any finite field. For any prime $p$, the $p$-adic valuation map is given
by $\psi_{p}:K/\{0\} \to \R^+\bigcup\{0\}$ is given by $\psi_{p}(r) = n$ where $r =
p^n \frac{a}{b}$, where $p,a,b$ are relatively prime. The field $K$ together with a
valuation is called valued field. Also, any field $K$ has the trivial valuation
determined by $\psi{(K)} = \{0,1\}$. Through out the paper K represents $\Z_q$. In this paper, we construct the graph
corresponding to the valuation map called the valued field graph, denoted by
$VFG_{p}(\Z_{q})$ whose vertex set is $\{v_0,v_1,v_2,\ldots, v_{q-1}\}$ where two
vertices $v_i$ and $v_j$ are adjacent if $\psi_{p}(i) = j$ or $\psi_{p}(j) = i$.
Here, we tried to characterize the valued field graph in $\Z_q$. Also we analyse various graph theoretical parameters such as diameter, independence number etc.
Sodan ja jälleenrakennuksen muistitieto vammaisten ihmisten elämäntarinoissa
Authors: Tarvainen Merja
Published: May 2020

Artikkeli käsittelee toisen maailmansodan (1939–1945) ja sen jälkeisten vuosien muistelukerrontaa elämäntarinan säikeenä tutkimalla, millaista on sota- ja jälleenrakennusajan muistelukerronta Vammaisena Suomessa 2013–2014 -elämäkertakokoelmassa. Tutkimuksen metodologinen perusta on tarinallisen kiertokulun malli, jonka ytimiä ovat sisäinen ja kerrottu tarina sekä kulttuurinen tarinavaranto. Vammaisten ihmisten yhteys tarinalliseen kiertokulkuun on usein esteellistä, mutta esteisyys rakentuu suhteessa kerrottavaan aiheeseen. Sota-aika määrittyi elämäntarinan aineellisena ja kerronnallisena olosuhteena, jonka vaikutukset saattoivat ulottua myös myöhempään elämänkulkuun. Jälleenrakennusajan muistelukerronta kiteytyy ristiriitaisten tunteiden kerronnallistumiseen aineellisten kiinnekohtien ja ruumiillisen työn kautta. Raskaita muistoja sanallistettiin esineiden ja paikkojen avulla, jotka välittävät menneisyyden tunnemaailmoja. Yhteys kulttuuriseen tarinavarantoon rakentuu suhteessa kerrottuun teemaan ja saavutettavissa oleviin resursseihin, ja yhteys erilaisiin kulttuurisiin tarinaresursseihin vahvistaa kertovaa toimijuutta ja elämäntarinan rakentamista. Mitä moninaisemmin ihmisellä on mahdollisuus käyttää tarinallisia resursseja elämäntarinansa rakentamiseen, sitä vahvemmaksi hänen narratiivinen toimijuutensa rakentuu. Tämä vahvistaa myös (narratiivista) osallisuutta.

Strengthening the visions of students as proficient L2 speakers: A teaching proposal for the EFL classroom
Authors: García Pinar Aranzazu
Published: May 2020

Over the past ten years, research on second language motivation has been dominated by Dörnyei’s influential motivational paradigm, the L2 Motivational Self System. This theoretical construct is comprised of the ideal L2 self, the ought-to L2 self and the L2 learning experience. Students’ imagined visualisations are central components in this theory, as this holds that students who have an explicit ideal self-image with an L2 component are more likely to be motivated to learn a language than other students that have not established a desired future state goal for themselves. To enhance students’ future-self-images, L2 lecturers can create adequate L2 learning experiences, where methodologies and materials fit in with the students’ needs, and where their visions as proficient users of the L2 are regularly sustained and strengthened by productive and realistic tasks. This article offers a teaching proposal that uses multimodal TED conferences as classroom artefacts to embolden students in the foreign language classroom to speak in public. These students might, if able to visualise their desired language selves portrayed in TED speakers, be motivated to spread their ideas worth spreading.

Financial statement is one of the essential thing in managing finance in an organization. Both profit oriented organizations and non profit oriented organizations requires relevant, reliable, comparable and understandable information in financial statements presented. Moreover, the non profit organizations, which the largest source of funding is donated from donors, the possibility of fraud becomes bigger. It is usually done by several parties, even by the management itself. Therefore, the diclosure of relevant, reliable, comparable, and understandable financial statements, are necessary done by the non profit organizations. The disclosure of financial statement needs a healthy organization management, good strategic management, finance report based on the accounting standards (PSAK 45) and good technology utilization. The technology utilization by web based financial statement are expected to be faster in presenting the non profit organization financial statement. With the stages of process that are undertaken, hopefully it will increase transparency of accountability for the donors.

Does vision extract absolute distance from vergence?
Authors: Linton Paul
Published: May 2020

Since Kepler (1604) and Descartes (1637), ‘vergence’ (the angular rotation of the eyes) has been thought of as one of our most important absolute distance cues. But vergence has never been tested as an absolute distance cue divorced from obvious confounding cues such as binocular disparity. In this article, we control for these confounding cues for the first time by gradually manipulating vergence and find that observers fail to accurately judge distance from vergence. We consider several different interpretations of these results and argue that the most principled response to these results is to question the general effectiveness of vergence as an absolute distance cue. Given that other absolute distance cues (such as motion parallax and vertical disparities) are limited in application, this poses a real challenge to our contemporary understanding of visual scale.
DYNAMIC SIGNALS FILTRATION IN HIGH LEVEL NOISE CONDITION
Authors: Hvozdzeu Matsvei , Karpovich Maksim
Published: May 2020

To examine the opportunity of measuring bulk solids consumption the experimental setup was developed. The main problem was the presence of a non-harmonic signal at the output. Almost always there are some difficulties to build measuring circuits using non-harmonic signals. It is necessary to use one of the approximation methods to receive a wanted signal without noise. For this purpose, the local approximation method was chosen. The developed technique confirmed its positive aspects and allowed to solve the questions that were posed before the experimental setup.
SURFACE WAVE SCATTERING BY AN ELASTIC PLATE SUBMERGED IN WATER WITH UNEVEN BOTTOM
Authors: Kundu Souvik , Gayen Rupanwita
Published: May 2020

Wave interaction with a vertical elastic plate in presence of undulating bottom topography
is considered, assuming linear theory and utilizing simple perturbation analysis. First order correction to the
velocity potential corresponding to the problem of scattering by a vertical elastic plate submerged in a fluid
with a uniform bottom is obtained by invoking the Green’s integral theorem in a suitable manner. With sinusoidal
undulation at the bottom, the first-order transmission coefficient (T1) vanishes identically. Behaviour of the
first order reflection coefficient (R1) depending on the plate length, ripple number, ripple amplitude and flexural
rigidity of the plate is depicted graphically. Also, the resonant nature of the first order reflection is observed
at a particular value of the ratio of surface wavelength to that of the bottom undulations. The net reflection
coefficient due to the joint effect of the plate and the bottom undulation is also presented for different flexural
rigidity of the plate. When the rigidity parameter is made sufficiently large, the results for R1 reduce to the known
results for a surface piercing rigid plate in water with bottom undulation.
NEW GENERAL DECAY RATES OF SOLUTIONS FOR TWO VISCOELASTIC WAVE EQUATIONS WITH INFINITE MEMORY
Authors: Guesmia Aissa
Published: May 2020

We consider in this paper the problem of asymptotic behavior of solutions for two viscoelastic wave equations with infinite memory. We show that the stability of the system holds for a much larger class of kernels and get better decay rate than the ones known in the literature. More precisely, we consider infinite memory kernels satisfying, where and are given functions. Under this very general assumption on the behavior of g at infinity and for each viscoelastic wave equation, we provide a relation between the decay rate of the solutions and the growth of g at infinity, which improves the decay rates obtained in [15, 16, 17, 19, 40]. Moreover, we drop the boundedness assumptions on the history data considered in [15, 16, 17, 40].

Published: May 2020

We monitored the z = 0.158 quasar 3C 273 between 2015 and 2019 in the optical (BVrz) and near-infrared (JHK) with the aim to perform dust reverberation mapping. Accounting for host galaxy and accretion disk contributions, we obtained pure dust light curves in JHK. Cross correlations between the V band and the dust light curves yield an average rest-frame delay for the hot dust of τ
cent ∼ 410 days. This is a factor of two shorter than that expected from the the dust ring radius R

x
 ∼ 900 lt-day reported from interferometric studies. The dust covering factor (CF) is about 8%, much smaller than that predicted from the half covering angle of 45° found for active galactic nuclei (AGNs). We analyze the asymmetric shape of the correlation functions and explore whether an inclined biconical bowl-shaped dust torus geometry could bring these findings (τ
cent, R

x
and CF) into a consistent picture. The hot varying dust emission originates from the edge of the bowl rim with a small covering angle 40° < θ < 45°, and we see only the near side of the biconus. Such a dust gloriole with R

x
 = 900 ± 200 lt-day and an inclination 12° matches the data remarkably well. Comparing the results of 3C 273 with literature for less luminous AGN, we find a lag–luminosity relation τ ∝ L

α
with α = 0.33–0.40, flatter than the widely adopted relation with α ∼ 0.5. We address several explanations for the new lag–luminosity relation.
Data-driven Detection of Multimessenger Transients
Authors: Sadeh Iftach
Published: May 2020

The primary challenge in the study of explosive astrophysical transients is their detection and characterization using multiple messengers. For this purpose, we have developed a new data-driven discovery framework, based on deep learning. We demonstrate its use for searches involving neutrinos, optical supernovae, and gamma-rays. We show that we can match or substantially improve upon the performance of state-of-the-art techniques, while significantly minimizing the dependence on modeling and on instrument characterization. Particularly, our approach is intended for near- and real-time analyses, which are essential for effective follow-up of detections. Our algorithm is designed to combine a range of instruments and types of input data, representing different messengers, physical regimes, and temporal scales. The methodology is optimized for agnostic searches of unexpected phenomena, and has the potential to substantially enhance their discovery prospects.
Multiphase Gas and the Fractal Nature of Radiative Turbulent Mixing Layers
Authors: Fielding Drummond B. , Ostriker Eve C. , Bryan Greg L. , Jermyn Adam S.
Published: May 2020

A common situation in galactic and intergalactic gas involves cold dense gas in motion relative to hot diffuse gas. Kelvin–Helmholtz instability creates a turbulent mixing layer and populates the intermediate-temperature phase, which often cools rapidly. The energy lost to cooling is balanced by the advection of hot high enthalpy gas into the mixing layer, resulting in growth and acceleration of the cold phase. This process may play a major role in determining the interstellar medium and circumgalactic medium phase structure, and accelerating cold gas in galactic winds and cosmic filaments. Cooling in these mixing layers occurs in a thin corrugated sheet, which we argue has an area with fractal dimension D = 5/2 and a thickness that adjusts to match the hot phase mixing time to the cooling time. These cooling sheet properties form the basis of a new model for how the cooling rate and hot gas inflow velocity depend on the size L, cooling time of the mixed phase

, relative velocity

, and density contrast

of the system. Entrainment is expected to be enhanced in environments with short

, large

, and large

. Using a large suite of three-dimensional hydrodynamic simulations, we demonstrate that this fractal cooling layer model accurately captures the energetics and evolution of turbulent interfaces and can therefore be used as a foundation for understanding multiphase mixing with strong radiative cooling.

Published: May 2020

Species of the genus Retiboletus in China were investigated based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU) and the translation elongation factor 1-α gene (TEF1-α). Nine species were recovered from China, including two new and seven known species. The new species, namely Retiboletus ater and R. sinogriseus, from southwestern and northeastern China respectively, are documented and illustrated in this paper. Retiboletus ater is morphologically characterized by its black to grayish black pileus, white to grayish hymenophore, black to blackish stipe and white to grayish white context. Retiboletus sinogriseus is morphologically characterized by its brown to grayish-brown pileus, yellow to grayish-yellow hymenophore, pale yellow to brownish stipe and yellow to brownish-yellow context. Descriptions and line drawings of these two novel species and their comparisons with allied taxa are presented.
The first Laboulbeniales (Ascomycota, Laboulbeniomycetes) from an American millipede, discovered through social media

Published: May 2020

Laboulbeniales are highly specialized arthropod-associated fungi. The majority of the almost 2200 known species live on insects, although they also occur on other arthropod hosts. Recently, the number of Laboulbeniales associated with millipedes has increased considerably. Here we describe the first species of a Laboulbeniales fungus, Troglomyces twitterisp. nov., from an American millipede. The new species was initially discovered on a photo of Cambala annulata (Say, 1821) from Ohio, USA, which had been shared on Twitter. A subsequent microscopic study of Cambala millipedes in museum collections in Denmark and France confirmed the discovery.

Captive reptiles are routinely identified as reservoirs of pathogenic bacteria and reports of reptile-associated infections relating to some species are well documented (e.g., salmonellosis). Currently, relatively little is known about the epidemiology and bacteria of ball pythons. We carried out a survey of ball python farms in Togo, West Africa to assess the presence of any potentially pathogenic bacterial taxa that have been identified in recent scientific literature relating to this species. The presence of bacteria belonging to the genera Acinetobacter, Bacteroides, Citrobacter, Enterobacter, Lysobacter, Proteus, Pseudomonas, Staphylococcus, and Tsukamurella in oral and cloacal samples taken from five individual ball pythons is of potential concern for horizontal transmission given that pathogenic species belonging to these genera have been previously documented. The presence of bacteria belonging to the genera Clostridium, Escherichia, Moraxella, and Stenotrophomonas in the oral and rectal samples taken from five mice used to feed ball pythons suggests that they represent a potential reservoir of infection for wild caught ball pythons and their progeny. Furthermore, possible sources of environmental contamination include other captive amphibians, birds, reptiles and mammals, as well as free ranging birds and small mammals. Additional surveillance of ball pythons in the wild and in captivity at python farms in West Africa will shed light on whether or not this type of commercial activity is increasing pathogen exposure and lowering barriers to transmission. Meanwhile, as a precautionary measure, it is recommended that python farms should immediately establish biosecurity and disease surveillance practices to minimize potential horizontal and vertical bacterial transfer.

The pathology of the hepatobiliary system significantly affects the state of the organs of the oral cavity. A clinical and index study of the state of periodontal tissues in 122 patients was conducted, which showed the prevalence of periodontal disease in patients with chronic acalculous cholecystitis. The examined patients were divided into groups depending on the treatment method, and the result was evaluated before treatment, directly after treatment and 6 months following treatment. Antidysbiotic hepatoprotector and 2% thiotriazolin ointment were included in the combination therapy. Studies have shown that patients with hepatobiliary pathology have increased likelihood of periodontal diseases, and after treatment, periodontal indicators and the hygiene index are significantly reduced, especially in the group where the proposed scheme was used, and the long-term results were stable for 6 months.
An oral live attenuated vaccine strategy against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2/2019-nCoV)
Authors: Sanal Madhusudana Girija , Dubey Ravi Chandra
Published: May 2020

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2/2019-nCoV) infection has become a pandemic called COVID-19. The virus binds to angiotensin converting enzyme 2 (ACE2) and TMPRSS2 which are abundantly expressed on various human cells including lung epithelial cells and intestinal cells and the virus can infect these cells. Currently no specific treatments or vaccines are available for this disease. A per oral live attenuated vaccine can be a good strategy in SARS-CoV-2 infection because the attenuated virus initially infects the gut, stimulates the mucosa associated immune system sparing the respiratory system during the initial immune response. The live virus can also spread in the community boosting herd immunity.
Une épure de chapiteau corinthien gigantesque gravée sur le parvis du mausolée d’Auguste
Authors: Capelle Jeanne
Published: May 2020

À Rome, sur un dallage devant le mausolée d’Auguste, on connaît un ensemble d’épures, pour certaines déjà attribuées par Lothar Haselberger à la construction du Panthéon, tandis que d’autres doivent concerner les projets d’autres édifices. Cet article s’intéresse à une épure de chapiteau corinthien gigantesque pour laquelle on n’avait pas encore trouvé de monument correspondant. Trois sont proposés, dans lesquels les dimensions des colonnes, de 60 pieds de haut, pourraient concorder avec le chapiteau : le temple de Vénus et de Rome, certes éloigné du Champ de Mars, le temple de Trajan et de Plotine à l’extrémité de la via Lata , la colonne d’Antonin le Pieux sur le Champ de Mars enfin. Le fait que trois monuments majeurs antonins possèdent des colonnes de dimensions très proches, sinon identiques amène à se demander si l’épure n’a pas pu servir de référence commune à des chantiers organisés de façon centralisée.
Il cibo e la dea: il magmentarium di Tellus e il lectisternium di Cerere
Authors: Marcattili Francesco
Published: May 2020

L’article analyse la fonction du magmentarium , sacellum appartenant au sanctuaire de Tellus dans le quartier romain des Carinae et, selon Cicéron (Cic., har. resp. , 30-32), annexé d’une manière sacrilège au vestibule de la demeure d’Appius Claudius Pulcher, frère de Clodius. Le réexamen du mot magmentum démontre que le magmentarium Telluris abritait le lectisternium célébré le 13 décembre à l’occasion de l’anniversaire du temple ( dies natalis ). Le fait que, en certaines occasions, le rituel du lectisternium ait été célébré à titre privé, semble expliquer l’annexion du magmentarium à la maison d’Appius Claudius ; annexion qui révèle la volonté de la famille des Claudiens de contrôler une partie significative du culte de Tellus. À la fin de notre étude, nous donnons une définition des fana magmentaria mentionnés par Varron ( ling. , 5, 112), avec quelques notes sur la consécration des mensae dans les sanctuaires.
Une nouvelle colonne funéraire en Gaule Narbonnaise (Avignon, Vaucluse)
Authors: Lefebvre Caroline , Toutain Nataëlle , De Michèle Patrick
Published: May 2020

À l’automne 2017, une opération archéologique a été réalisée au sud-est de la ville d’Avignon (Vaucluse), au lieu-dit « Bel Air ». Cette intervention consistait à sonder un vaste terrain d’une superficie d’environ 275 000 m² dans le but d’évaluer le potentiel archéologique du secteur. Dans un des sondages, a été mise au jour une structure antique identifiée comme un possible renforcement d’une portion de voirie, mis en œuvre au moyen d’éléments lapidaires réemployés. Parmi ces derniers, ont été reconnus des stèles anépigraphes et des blocs d’architecture. L’analyse typologique et comparative des pièces architecturales a permis de mettre en évidence, pour certaines d’entre elles, une appartenance à un même monument. Leur mise en parallèle avec d’autres éléments architecturaux découverts à proximité ou dans une zone géographique relativement proche (Mouriès, Saint-Rémy-de-Provence et Beaucaire), nous autorise à proposer ici l’existence d’un nouvel exemplaire de colonne funéraire en Narbonnaise.
La démocratie selon Platon ou de l’ignorance collective érigée en principe politique
Authors: Gavray Marc-Antoine
Published: May 2020

La critique platonicienne de la démocratie est résolument philosophique, contestant le modèle anthropologique et épistémologique sous-jacent au nom des aberrations historiques auxquelles il est condamné. Cet article examine les deux principaux moteurs de l’analyse platonicienne : 1) l’absence d’unité, qui se traduit par une oligarchie de fait et par une dispersion des citoyens, plus soucieux de leur liberté individuelle que de l’intérêt de la cité ; 2) une théorie de la connaissance qui, aussi implicite soit-elle, dissocie savoir et pouvoir. Il en résulte une prise de distance à l’égard d’un modèle où l’homme démocratique serait jugé compétent par nature à exercer des responsabilités.
Habermas : la démocratie au point de vue cosmopolitique
Authors: Pratt Valéry
Published: May 2020

Habermas élabore une théorie radicale de la démocratie qui entend répondre aux défis posés tant par la mondialisation économique que par la tentation de repli des « peuples » qui cherchent à retrouver une souveraineté perdue. Une telle théorie, qui prend une forme délibérative, projette la démocratie dans la constitutionnalisation du droit international, et implique une perspective cosmopolitique. Dans ce cadre, la réflexion sur la politique européenne et ses institutions est centrale, et permet de montrer que la théorie critique n’a rien perdu de sa lucidité quand il s’agit de mettre en garde notamment contre un « fédéralisme postdémocratique de l’exécutif » dans lequel l’Europe risque de se perdre.

Voici une expérience aussi exemplaire que fructueuse. Depuis 1998, le consortium interuniversitaire canadien Érudit ( erudit.org ) soutient et valorise près de 200 revues de Sciences humaines et sociales (SHS). Vingt ans plus tard, en 2018, Érudit, devenu une véritable infrastructure de recherche au service de la science ouverte, a établi un partenariat avec le consortium français Couperin pour favoriser le libre accès. Corédigé par Érudit et Couperin, cet article présente le modèle partenarial et le chemin parcouru pour le déployer en France, ses impacts positifs (économiques notamment) et les défis à venir pour assurer sa pérennité.
