Authors: Ilahin Nur
Published: April 2022

Tiktok social media has recently become a trend for young people, especially for the character of elementary school children. This type of research is qualitative research that we conducted in class V MI Banin Banat Siman Lamongan. The data collection technique in this research is using the descriptive method. Documentation data is the character of students, namely obedient attitudes and behavior in carrying out their religious teachings and actions that show orderly behavior and obey various provisions and regulations. Data analysis uses statistical analysis, namely interpretations and conclusions made based on statistical analysis to find out how much influence the use of social media has on the character of students. The results of the study show that there is a significant influence on the use of tiktok social media on the character of students. From the results of preliminary research conducted by analysts, it is obtained that the use of online media tiktok can affect the character of these students. So that this tiktok application-based media is an external factor that affects the character of students. Many of them use online media too often, which makes them sluggish to learn. In addition, it is very disappointing for students' actual learning outcomes the next day.

Advancement in scientific research depends on the availability and sharing of information and ideas. Many authors proposed many methodologies for isolation preserving data mining for centralized as well as for distributed database. The core intend of this paper work is, to develop efficient methodologies to find privacy preserving association rule mining in centralized as well as in distributed database environment without violating any privacy constraints. The issue of privacy constraints for centralized database environment is entirely different from distributed database environment. So the approaches for privacy preserving association rule mining in centralized are also different from approaches in distributed environment. Achieving privacy preserving goals in both these environments in the process of mining is a challenging task.

Every day we are participants in various marketing advertisements. Wherever we turn at every turn, we can see at least one bit of marketing and try to communicate businesses to their products or services through marketing activities. Tempting sentences at once distract us and intrigue us to continue reading or watching a commercial or marketing view. The purpose of the research is to look at where and in what marketing activities manipulation is hidden and how and how marketing tricks using manipulation tactics influence the change in our attitude of behavior and attitude of buying certain advertised products or services. Research with a method of experiment has assessed aspects of manipulative advertising, their execution, and expected impacts on consumer behaviour in general about any purchase of a product or service worldwide. Analysis of the collected primary data revealed that manipulation in marketing is quite common and occurs at every step and has begun to be one of the main players when creating marketing ventures and actions.
Scientific and technological progress and transformation of society: noonomy and noosociety. Part 1
Authors:   S.Y. Witte Institute for New Industrial Development, Bodrunov S.D.
Published: April 2022

The theory of Noonomy, based on the study of modern trends in technological and socio-economic development, allows us to identify the causes of the contradictions that modern civilization faces – economic, social, environmental, moral contradictions. However, noonomy not only reveals the background of these contradictions, but also shows the maturing objective possibilities of getting out of these contradictions, overcoming civilizational dead ends, choosing a path at civilizational forks. The opportunities created by modern technology create the prospect of a transition from economics to noonomy, which means abandoning economic rationality, leading to an unrestrained pursuit of increasing production and consumption. The place of economic rationality is occupied by rationality based on the criteria of knowledge and culture. However, such a transition from economics to noonomy should be based on a change in the totality of social relations, and noonomy can be strengthened only within the framework of an integral system of the noosociety. The very nature of public relations and public relations of people, the nature of human socialization and socialization of society will orient social development to these new criteria. The ideological orientation of such a reformatting of society can be the ideology of solidarity, which grows out of the emerging opportunities to overcome the discord of socio-economic interests of people based on the struggle for material resources.

Authors: Nam Ga Eun , Huh Youn , Jung Jin-Hyung , Han Kyungdo , Kim Seon Mee ,   on Behalf of the Taskforce Team of the Obesity Fact Sheet of the Korean Society for the Study of Obesity
Published: April 2022

Background: We investigated whether low high-density lipoprotein cholesterol (HDL-C) and isolated and non-isolated low HDL-C levels are associated with the risk of cardiovascular diseases and all-cause mortality among Korean adults.Methods: We included 8,665,841 individuals aged ≥20 years who had undergone a health examination provided by the Korean National Health Insurance Service (NHIS) in 2009 and were followed up until the end of 2018. The hazard ratios (HRs) and 95% confidence intervals (CIs) for study outcomes were calculated using multivariable Cox proportional hazard regression analysis.Results: During the 8.2 years of mean follow-up, myocardial infarction (MI), stroke, and all-cause mortality occurred in 81,431, 110,996, and 244,309 individuals, respectively. After adjusting for confounding variables (model 3), individuals with low HDL-C and lower HDL quartiles were associated with significantly increased risks of all three outcomes, compared to those with normal HDL-C and highest HDL-C quartile (all P<0.001), respectively. HRs for incident MI (1.28; 95% CI, 1.26 to 1.30), stroke (1.13; 95% CI, 1.11 to 1.15), and all-cause mortality (1.07; 95% CI, 1.05 to 1.08) increased in the non-isolated low HDL-C group compared to the normal HDL-C group. Isolated low HDL-C also showed an increase in the HRs of incident stroke (1.06; 95% CI, 1.04 to 1.08) and all-cause mortality (1.30; 95% CI, 1.28 to 1.32).Conclusion: Low HDL-C and non-isolated low HDL-C were associated with increased risk of MI, stroke, and all-cause mortality, and isolated low HDL-C was associated with incident stroke and all-cause mortality risk.
The Presence of Clonal Hematopoiesis Is Negatively Associated with Diabetic Peripheral Neuropathy in Type 2 Diabetes
Authors: Oh Tae Jung , Song Han , Koh Youngil , Choi Sung Hee
Published: April 2022

Background: Clonal hematopoiesis of indeterminate potential (CHIP) has been reported to be associated with increased cardiovascular disease, aging and insulin resistance. Despite the debate of causal contribution of CHIP on metabolic diseases, we want to explore whether CHIP is related to diabetic peripheral neuropathy (DPN).Methods: This study analyzed the prevalence of CHIP in patients with type 2 diabetes classified according to DPN status. Logistic regression analysis was used to evaluate the association between CHIP and DPN.Results: CHIP was more prevalent in subjects without DPN than those with DPN (19.9% vs. 8.8%, respectively; P=0.013). Individuals having any CHIP, or DNA methyltransferase 3A (DNMT3A) CHIP were less likely to have any abnormality shown in DPN test; the adjusted odds ratio were 0.85 (95% confidence interval [CI], 0.73 to 1.00) and 0.70 (95% CI, 0.56 to 0.89), respectively. Interestingly, DNMT3A CHIP showed the negative association, but Tet methylcytosine dioxygenase 2 (TET2) CHIP showed the positive association with abnormal feet electrochemical skin conductance level.Conclusion: On the contrary to expectations, CHIP was negatively associated with DPN. Functional linking between the mutation in hematopoietic cells and DPN, and the opposite role of DNMT3A and TET2 should be investigated.
REVERSE MORTGAGE AND FINANCIAL SUSTAINABILITY
Authors: Boj Eva , Claramunt M. Mercè , Varea Xavier
Published: April 2022

This paper analyzes the effects that contracting a reverse mortgage has on the finances of families of a country or group whose members who aged 65 or older are the sole owners of the 100% of the property, regardless of the receipt of a retirement pension. For this purpose, an economic-financial model based on the life cycle model is defined, which considers a double source of randomness: mortality and dependence of family members. Long-term effects are measured using probabilistic, temporal and monetary indicators. For each country, the model must be adapted according to the legal framework for retirement and long-term care benefits and for the actuarial mortality and long-term care tables. As an illustration, this model was applied on Spanish families using data from the Spanish Survey of Household Finances 2017. The results obtained indicate that a family in Spain that meets the conditions for contracting a reverse mortgage sees, on average, an increase in its initial income and a decrease in both its probability of having liquidity problems in the future and the value of this lack of liquidity. It is also concluded that family composition influences the magnitude of these positive effects.

Published: April 2022

Based on analysis of high-precision photometry from the Transiting Exoplanet Survey Satellite combining with spectroscopy from the medium-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope, we investigated five double-lined spectroscopic eclipsing binaries (TIC 0165626871, TIC 0159105847, TIC 0122446076, TIC 0349294422, and TIC 0155968973). With the help of Wilson–Devinney program, we accurately derived their absolute stellar parameters. TIC 0165626871, TIC 0159105847, and TIC 0122446076 were identified as detached binaries, while TIC 0349294422 and TIC 0155968973 were recognized as A-subtype and W-subtype W UMa-type systems, respectively. Especially, absolute parameters of four binaries except for TIC 0122446076 were obtained for the first time. TIC 0165626871 also shows light variations of out-of-eclipse phases, which are probably contributed by starspots. The light pulsations of TIC 0122446076 could originate from the primary star that is located in the classical Cepheid instability strip. Evolutionary states of all stars were also discussed.

TESS has proven to be a powerful resource for finding planets, including those that orbit the most prevalent stars in our galaxy: M dwarfs. Identification of stellar companions (both bound and unbound) has become a standard component of the transiting planet confirmation process in order to assess the level of light-curve dilution and the possibility of the target being a false positive. Studies of stellar companions have also enabled investigations into stellar multiplicity in planet-hosting systems, which has wide-ranging implications for both exoplanet detection and characterization, as well as for the formation and evolution of planetary systems. Speckle and AO imaging are some of the most efficient and effective tools for revealing close-in stellar companions; we therefore present observations of 58 M-dwarf TOIs obtained using a suite of speckle imagers at the 3.5 m WIYN telescope, the 4.3 m Lowell Discovery Telescope, and the 8.1 m Gemini North and South telescopes. These observations, as well as near-infrared adaptive optics images obtained for a subset (14) of these TOIs, revealed only two close-in stellar companions. Upon surveying the literature, and cross-matching our sample with Gaia, SUPERWIDE, and the catalog from El-Badry et al., we reveal an additional 15 widely separated common proper motion companions. We also evaluate the potential for undetected close-in companions. Taking into consideration the sensitivity of the observations, our findings suggest that the orbital period distribution of stellar companions to planet-hosting M dwarfs is shifted to longer periods compared to the expected distribution for field M dwarfs.
ALMA Detections of [O iii] and [C ii] Emission Lines From A1689-zD1 at z = 7.13

A1689-zD1 is one of the most distant galaxies, discovered with the aid of gravitational lensing, providing us with an important opportunity to study galaxy formation in the very early universe. In this study, we report the detection of [C ii]158 μm and [O iii]88 μm emission lines of A1689-zD1 in the Atacama Large Millimeter/submillimeter Array (ALMA) Bands 6 and 8. We measure the redshift of this galaxy as z
sys = 7.133 ± 0.005 based on the [C ii] and [O iii] emission lines, consistent with that adopted by Bakx et al. The observed L
[O III]/L
[C II] ratio is 2.09 ± 0.09, higher than that of most of the local galaxies, but consistent with other z ∼ 7 galaxies. The moderate spatial resolution of ALMA data provided us with a precious opportunity to investigate spatial variation of L
[O III]/L
[C II]. In contrast to the average value of 2.09, we find a much higher L
[O III]/L
[C II] of ∼7 at the center of the galaxy. This spatial variation of L
[O III]/L
[C II] was seldom reported for other high-z galaxies. It is also interesting that the peak of the ratio does not overlap with optical peaks. Possible physical reasons include a central active galactic nucleus, shock heating from merging, and a starburst. Our moderate spatial resolution data also reveal that in addition to the observed two clumps shown in previous Hubble Space Telescope images, there is a redshifted segment to the west of the northern optical clump. This structure is consistent with previous claims that A1689-zD1 is a merging galaxy, but with the northern redshifted part being some ejected material, or that the northern redshifted material stems from a third more highly obscured region of the galaxy.

We report on the variation in the single-pulse emission from PSR J1900+4221 (CRAFTS 19C10) observed at frequency centered at 1.25 GHz using the Five-hundred-meter Aperture Spherical radio Telescope. The integrated pulse profile shows two distinct components, referred to here as the leading and trailing components, with the latter component also containing a third weak component. The single-pulse sequence reveals different emissions demonstrating as nulling, regular, and bright pulses, each with a particular abundance and duration distribution. There also exists pulses that follow a log-normal distribution suggesting the possibility of another emission, in which the pulsar is radiating weakly. Changes in the profile shape are seen across different emissions. We examine the emission variations in the leading and trailing components collectively and separately, and find moderate correlation between the two components. The inclination angle is estimated to be about 7° based on pulse-width, and we discuss that nulling in this pulsar does not seem to show correlation with age and rotation period.
Disruption of a Planetary Nitrogen Cycle as Evidence of Extraterrestrial Agriculture
Authors: Haqq-Misra Jacob , Fauchez Thomas J. , Schwieterman Edward W. , Kopparapu Ravi
Published: April 2022

Agriculture is one of the oldest forms of technology on Earth. The cultivation of plants requires a terrestrial planet with active hydrological and carbon cycles and depends on the availability of nitrogen in soil. The technological innovation of agriculture is the active management of this nitrogen cycle by applying fertilizer to soil, at first through the production of manure excesses but later by the Haber–Bosch industrial process. The use of such fertilizers has increased the atmospheric abundance of nitrogen-containing species such as NH3 and N2O as agricultural productivity intensifies in many parts of the world. Both NH3 and N2O are effective greenhouse gases, and the combined presence of these gases in the atmosphere of a habitable planet could serve as a remotely detectable spectral signature of technology. Here we use a synthetic spectral generator to assess the detectability of NH3 and N2O that would arise from present-day and future global-scale agriculture. We show that present-day Earth abundances of NH3 and N2O would be difficult to detect, but hypothetical scenarios involving a planet with 30–100 billion people could show a change in transmittance of about 50%–70% compared to preagricultural Earth. These calculations suggest the possibility of considering the simultaneous detection of NH3 and N2O in an atmosphere that also contains H2O, O2, and CO2 as a technosignature for extraterrestrial agriculture. The technology of agriculture is one that could be sustainable across geologic timescales, so the spectral signature of such an “ExoFarm” is worth considering in the search for technosignatures.
On the Phase-mixed Eccentricity and Inclination Distributions of Wide Binaries in the Galaxy
Authors: Hamilton Chris
Published: April 2022

Modern observational surveys allow us to probe the distribution function (DF) of the Keplerian orbital elements of wide binaries in the solar neighborhood. This DF exhibits nontrivial features, in particular a superthermal distribution of eccentricities for semimajor axes a ≳ 103 au. To interpret such features we must first understand how the binary DF is affected by dynamical perturbations, which typically fall into two classes: (i) stochastic kicks from passing stars, molecular clouds, etc. and (ii) secular torques from the Galactic tide. Here we isolate effect (ii) and calculate the time-asymptotic, phase-mixed DF for an ensemble of wide binaries under quadrupole-order tides. For binaries wide enough that the phase-mixing assumption is valid, none of our results depend explicitly on semimajor axes, masses, etc. We show that unless the initial DF is both isotropic in binary orientation and thermal in eccentricity, then the final phase-mixed DF is always both anisotropic and nonthermal. However, the only way to produce a superthermal DF under phase mixing is for the initial DF to itself be superthermal.

The hot intracluster medium (ICM) is thought to be quiescent with low observed velocity dispersions. Surface brightness fluctuations of the ICM also suggest that its turbulence is subsonic with a Kolmogorov scaling relation, indicating that the viscosity is suppressed and the kinetic energy cascades to small scales unscathed. However, recent observations of the cold gas filaments in galaxy clusters find that the scaling relations are steeper than that of the hot plasma, signaling kinetic energy losses and the presence of supersonic flows. In this work we use high-resolution simulations to explore the turbulent velocity structure of the cold filaments at the cores of galaxy clusters. Our results indicate that supersonic turbulent structures can be “frozen” in the cold gas that cools and fragments out of a fast, ∼107 K outflow driven by the central active galactic nucleus (AGN), when the radiative cooling time is shorter than the dynamical sound-crossing time. After the cold gas formation, however, the slope of the velocity structure function (VSF) flattens significantly over short, ∼10 Myr timescales. The lack of flattened VSF in observations of Hα filaments indicates that the Hα-emitting phase is short-lived for the cold gas in galaxy clusters. On the other hand, the ubiquity of supersonic turbulence revealed by observed filaments strongly suggests that supersonic outflows are an integral part of AGN–ICM interaction, and that AGN activity plays a crucial role at driving turbulence in galaxy clusters.

Published: April 2022

BACKGROUND: Pre-eclampsia is characterized by severe inflammatory response and endothelial dysfunction that could lead to myocardial injury and remodeling. Biomarker examination such as soluble Suppression of Tumorigenicity 2 (sST2), which has been used as a marker for myocardial fibrosis and Global Longitudinal Strain (GLS) by echocardiography could be used to predict mortality and detect subclinical myocardial dysfunction. AIM: The purpose of this study was to determine the correlation between serum levels of sST2 and GLS in patients with pre-eclampsia 1 year postpartum. METHODS: This was a cross-sectional study with correlation analysis. GLS examination was done using EchoPAC workstation. Maternal plasma of sST2 was measured using the Presage ST2 Assay. Rank-Spearman correlation analysis was conducted to analyze the correlation between GLS and sST2 at delivery and 1 year postpartum. RESULTS: There were 30 subjects with pre-eclampsia who fulfilled the criteria. Average age was 33 ± 6 years and majority were multipara (76.7%) and early onset pre-eclampsia (76.7%) with sST2 value of 66.1 ± 7.7 ng/mL and GLS of −17 ± 0.4%. One year after delivery, the sST2 value is 22 ± 1.4 ng/mL and an average value GLS is −19.7 ± 0.4%. Analysis showed moderate positive correlation between sST2 and GLS at delivery (r = 0.439, p = 0.015), but there was no correlation between sST2 and GLS 1 year after delivery (r = 0.036, p = 0.961). CONCLUSIONS: This study demonstrates a significant correlation between sST2 and GLS at delivery in patients with pre-eclampsia but not in 1 year after delivery.
The effect of climate on age specific survival and senescence in a Hazel Dormouse (Muscardinus avellanarius) population in Lithuania, across 1997-2021
Authors: Berg Thomas , Colchero Fernando , Jones Owen , Sanderhoff Lene , Juškaitis Rimvydas
Published: April 2022

It is well known that survival and the dynamics of wild populations are affected by environmental factors. Recent research has found that, among some species of mammal, differences in environmental conditions between populations of the same species translate into changes in infant and juvenile mortality, but not in the rate of senescence (‘rate of aging’). This has been confirmed among primates and some species of carnivores, but has not been tested on other taxonomic groups, such as rodents. Here, we analyse age-specific survival and mortality on the most extensive capture-mark-recapture data set on Hazel Dormouse available from Lithuania. We used Bayesian survival trajectory analysis (BaSTA) and tested different models of age-specific mortality. Since the Hazel Dormouse population is in decline across its northern distribution, potentially in response to climate change, we divided the data into three periods to assess changes in survival over time. Regional climate data were obtained from the NOAA data service to test the effect of climatic factors on survival during winter and summer respectively. Our results show that, during all three periods, male life expectancies were longer than those of females. We found that the overall level of mortality was high for all three periods, with lowest mortality during the period 1999 - 2004. We found large differences in juvenile mortality and age-independent mortality between the three periods, but not in adult mortality or in the rate of senescence. This is consistent with previous findings on other mammals, supporting the invariant rate of aging hypothesis.
Jakob Emanuel Lange: The man and his mushrooms
Authors: Petersen Ronald H. , Knudsen Henning
Published: April 2022

Jakob Emanuel Lange (1864–1941), Danish mushroom taxonomist and illustrator, was an agricultural educator and economic philosopher. A follower and translator of the American Henry George, Lange was Headmaster of a “Small-holders High-School,” which served as a model for American folk-schools. Lange visited North America on three occasions. The first, in 1927, relied on his professional expertise; the second, in 1931, was purely mycological; and the third, 1939, was a combination of the two. All of this was lived against two World Wars and the Great Depression. This paper summarises the circumstances of Lange’s life against a background of the American mycologists of the day, the ominous events over his adult lifetime and his magnum opus, “Flora Agaricina Danica”, of five volumes illustrating ca. 1200 species on 200 coloured plates.
Le droit est le masque de la lutte
Authors: Ibos Caroline
Published: April 2022

À partir d’une observation menée dans un syndicat grassroots de travailleuses domestiques « salariées du particulier-employeur » (le SNAP/SPE), l’article analyse les usages du droit liés à ce que ces femmes qualifient de « discriminations ». Certaines d’entre elles, s’estimant victimes d’abus particulièrement dégradants, espèrent rétablir leur dignité par l’action contentieuse. Sollicité pour les conseiller et les assister dans leurs démarches, le syndicat cherche à la fois à obtenir réparation pour les plaignantes et à renforcer sa position sur la scène des relations professionnelles : par une utilisation pointilleuse de la convention collective, il cherche à requalifier la violence de race en violation du droit du travail. En mobilisant une approche intersectionnelle, cette contribution explore ainsi les stratégies complexes d’un collectif de femmes subalternes et racisées, pour lutter au croisement des rapports de domination, dans un contexte social qui, prompt à dénoncer le communautarisme, invisibilise la race.
Performance et exclusion

Cet article explore le développement du mouvement social des travailleuses domestiques migrantes au Liban ainsi que ses stratégies pour lutter contre leur exclusion d’une part, et celles des acteurs étatiques pour renforcer cette exclusion d’autre part. S’inspirant des travaux de Judith Butler sur la performance dans l’assemblée politique, ce texte avance l’importance de considérer la place du corps, et en particulier le corps au sein d’un mouvement intersectionnel, pour comprendre la signification politique de l’assemblée dans le cas des travailleuses domestiques migrantes, ainsi que les façons dont l’État tente de supprimer cette assemblée en ciblant le corps dans des actes tels que l’emprisonnement, la déportation et l’appel à la peur.

Le temps accompli. Note sur le tragique chez Walter Benjamin
Authors: Manfreda Luigi A. , La Rocca Fabio
Published: April 2022

Ce texte propose quelques considérations sur l’idée de tragédie chez Walter Benjamin. Dans l’ Ursprung des deutschen Trauerspiel et dans quelques courts écrits précédant l’ouvrage de 1928, Benjamin s’attarde sur l’idée de tragédie dans le but principal de mettre en évidence celle de Trauerspiel. Néanmoins, ses pages sur la tragédie antique sont très pénétrantes et mettent en évidence certains de ses motifs essentiels. Le héros tragique pour Benjamin vit dans un temps accompli, tout compris dans l’horizon du mythe. Son attitude, qui ne connaît aucune médiation, finit par le faire entrer en collision avec l’ethos consolidé de la polis , et le condamne ainsi au silence. Pour l’auteur de l’essai, ce silence inaugure néanmoins un nouveau dialogue dans les profondeurs de l’individualité du héros.
L’immersion du visionnaire. Intérieur/extérieur chez Walter Benjamin
Authors: Mons Alain
Published: April 2022

Walter Benjamin a été un visionnaire spécial se situant dans l’immersion du monde, et non pas dans une pureté transcendantale. Il a particulièrement pointé la compénétration subtile des choses entre elles, en pensant leur inséparation secrète. Ainsi en est-il de sa sensibilité extrême à la ville comme espace imaginaire du labyrinthe accompli à travers les passages, les glissements incessants entre les intérieurs et les extérieurs, matériels et mentaux. Les miroirs de la grande ville comme Paris ouvrent au phénomène des apparitions et des disparitions se succédant dans la potentialité de la multiplicité des regards et des sensations, et des espèces d’errance. Benjamin est à la fois un phénoménologue et un métaphysicien, il s’agit pour lui de percevoir et comprendre la transmorphose des situations urbaines, artistiques, amoureuses, corporelles, politiques, poétiques.
Le Printemps adorable a perdu son odeur. Benjamin, Simmel et l’expérience de la modernité : réflexions sociologiques
Authors: Cerulo Massimo
Published: April 2022

L’objectif de cet article est de réfléchir sur une série de ressemblances entre la théorie sociale de Walter Benjamin et celle de Georg Simmel relativement aux caractéristiques de la modernité. Dans la première partie, les formes principales assumées par l’expérience de la modernité seront approfondies selon l’analyse produite par Benjamin. Dans la deuxième partie, on examine les modalités à travers lesquelles la modernité influence la vie quotidienne des sujets dans les métropoles, selon la théorie de Simmel qui souligne en particulier le phénomène de l’intensification de la vie nerveuse. En même temps, une comparaison entre les deux auteurs sera proposée, en montrant la validité de leurs théories pour ce qui concerne la pratique de l’expérience émotionnelle dans la société postmoderne.
Retour sur une lecture de jeunesse des thèses sur la philosophie de l’histoire
Authors: Strohl Hélène
Published: April 2022

En 1971 paraît en France le premier recueil de textes de Walter Benjamin. L’auteure de cet article, alors très jeune étudiante en histoire et proche des idées de l’ultra-gauche allemande commente les « Thèses sur la philosophie de l’histoire » dans une longue introduction à une traduction d’un militant ultra-gauche allemand, Otto Rühle (1924). À l’époque, elle lit cet essai comme un hymne nostalgique célébrant les vaincus de l’histoire, les conseillistes allemands, les anarchistes espagnols. Mais n’est-ce pas la notion même de révolution, de prise de pouvoir qui génère la tristesse ? celle qui empêcha Walter Benjamin de repartir à l’assaut de la frontière espagnole pour un nouvel exil ?
Un imaginaire « dialogique » d’Umberto Eco dans La structure absente : le crépuscule de la raison
Authors: Portanova Barros Eduardo , Lopes Alves Fábio , Barcelos de Moura Abreu Claudia
Published: April 2022

Cet article traite de l’imaginaire du biais « dialogique » comme principe à la fois complémentaire et antagoniste de La structure absente d’Umberto Eco. Pour Eco, une épistémologie de la différence vise à montrer les diverses manières de caractériser la structure dont la nature n’est pas, à son avis, un facteur unique. Et, comme nous le verrons, c’est pour penser le caractère épistémique du terme « structure » qu’Eco y ajouta le mot « absent ». Mais pas comme un déni : comme un doute, une ouverture et une possibilité sur ce que nous appellerons, pour l’instant, un crépuscule de la Raison, le tragique.
Digitally topological groups
Authors: Han Sang-Eon
Published: April 2022

The purpose of the paper is to study digital topological versions of typical topological groups. In relation to this work, given a digital image $ (X, k), X \subset {\mathbb Z}^n $, we are strongly required to establish the most suitable adjacency relation in a digital product $ X \times X $, say $ G_{k^\ast} $, that supports both $ G_{k^\ast} $-connectedness of $ X \times X $ and $ (G_{k^\ast}, k) $-continuity of the multiplication $ \alpha: (X \times X, G_{k^\ast}) \to (X, k) $ for formulating a digitally topological $ k $-group (or $ DT $-$ k $-group for brevity). Thus the present paper studies two kinds of adjacency relations in a digital product such as a $ C_{k^\ast} $- and $ G_{k^\ast} $-adjacency. In particular, the $ G_{k^\ast} $-adjacency relation is a new adjacency relation in $ X \times X\subset {\mathbb Z}^{2n} $ derived from $ (X, k) $. Next, the paper initially develops two types of continuities related to the above multiplication $ \alpha $, e.g., the $ (C_{k^\ast}, k) $- and $ (G_{k^\ast}, k) $-continuity. Besides, we prove that while the $ (C_{k^\ast}, k) $-continuity implies the $ (G_{k^\ast}, k) $-continuity, the converse does not hold. Taking this approach, we define a $ DT $-$ k $-group and prove that the pair $ (SC_k^{n, l}, \ast) $ is a $ DT $-$ k $-group with a certain group operation $ \ast $, where $ SC_k^{n, l} $ is a simple closed $ k $-curve with $ l $ elements in $ {\mathbb Z}^{n} $. Also, the $ n $-dimensional digital space $ ({\mathbb Z}^n, 2n, +) $ with the usual group operation "$ + $" on $ {\mathbb Z}^n $ is a $ DT $-$ 2n $-group. Finally, the paper corrects some errors related to the earlier works in the literature.

Published: April 2022

This paper studies a semilinear fractional stochastic differential equation with multiple constant point delays in control. We transform the controllability problem into a fixed point problem. We obtain sufficient condition for the controllability by using Schauder's fixed point theorem. In addition, we discuss the optimal controllability of the problem. Some examples are given to illustrate the main result.
On the Waring–Goldbach problem for two squares and four cubes
Authors: Zhang Min , Xue Fei , Li Jinjiang
Published: April 2022

Let $ \mathcal{P}_r $ denote an almost–prime with at most $ r $ prime factors, counted according to multiplicity. In this paper, it is proved that for every sufficiently large even integer $ N $, the following equation

   \begin{document}$ \begin{equation*} N = p_1^2+p_2^2+x^3+p_3^3+p_4^3+p_5^3 \end{equation*} $\end{document}

is solvable with $ x $ being an almost–prime $ \mathcal{P}_7 $ and the other variables primes. This result constitutes a deepening upon that of previous results.

Published: April 2022

A new generalized $ (p, q) $-integral identity is derived. Using this new identity as an auxiliary result, we derive new parametric generalizations of certain integral inequalities using the class of $ s $-preinvex functions. We discuss several new and known special cases of the obtained results. This shows that our results are quite unifying. To demonstrate the significance of the main results, we also present some interesting applications.
High prevalence of blaVEB, blaGES and blaPER genes in beta-lactam resistant clinical isolates of Pseudomonas aeruginosa
Authors: Haghighi Saboura , Reza Goli Hamid
Published: April 2022

The increased prevalence of β-lactamase is one of the main factors in resistance to β-lactams in Pseudomonas aeruginosa. This study aimed to investigate the prevalence of blaVEB, blaPER, and blaGES genes in β-lactam-resistant P. aeruginosa. We collected 100 non-duplicated clinical isolates of P. aeruginosa and identified them by standard tests. Using disk agar diffusion test, we detected the β-lactam-resistant isolates and extracted the DNAs of the isolates by alkaline lysis method. Then, the prevalence of blaVEB, blaPER and blaGES genes were detected by PCR method. The results were assessed by SPSS 21 software and Chi-square test. Out of 100 isolates, 43% were detected as resistant against at least one of the beta-lactams tested. Piperacillin-tazobactam was the most effective antibiotic, while 39% and 37% of the isolates were resistant to aztreonam and meropenem, respectively. A significant relationship was observed between the resistance to tested antibiotics and the presence of blaVEB, blaGES, and blaPER genes. Among 43 isolates that were resistant to at least one of the tested β-lactams, 93.02%, 83.72%, and 81.39% of them carried blaVEB, blaGES, and blaPER genes, respectively. According to this study and due to high prevalence of β-lactam resistance genes, it is better to check the level of antibiotic resistance and resistance genes for better management of patients with infection caused by this bacterium. Also, high prevalence of class A β-lactamases indicates the significant role of these enzymes in emerging resistance to beta-lactams.
La muralla romana de Tortosa. Un proyecto defensivo de la Antigüedad Tardía
Authors: Ferré Anguix Ramon , Diloli Fons Jordi
Published: April 2022

Las excavaciones arqueológicas realizadas entre 2015 y 2020 frente a la Catedral de Santa María en Tortosa (Tarragona), han generado una gran cantidad de documentación sobre la evolución urbana de la ciudad en época antigua. Entre los restos exhumados destaca la localización de un tramo de 60 m de la muralla romana, construida presumiblemente entre finales del siglo IV y el inicio del siglo V, para proteger la fachada de ribera de Tortosa. Una de las características más destacables de esta fortificación es la utilización de la técnica del opus africanum en un tramo de su fachada exterior. Cabe indicar que el conocimiento sobre la muralla romana de Dertosa era prácticamente nulo hasta esta intervención. La construcción del muro defensivo afectó a una batería de tabernae edificadas en época alto-imperial, cuyas estructuras fueron reconstruidas y adaptadas como espacios aparentemente dependientes de la fortificación.

Published: April 2022

Current technological advancements urge institutions to generate graduates capable of contributing to the industrial world. Information Systems is one of the scientific subjects whose graduates play a significant part in the advancement of modern technology. As a result, lecturers in Information Systems education, particularly at the undergraduate level, must be able to retain and even improve students' interest in studying this field. Gamification is one method that can be used to accomplish this purpose. The goal of this study is to identify factors that determine the successful implementation of gamification for learning, particularly in the context of Information Systems Education at the undergraduate level. This study's methodology is based on a systematic literature review technique from previous studies. Motivation, engagement, perceived utility, game design, and student perspective were identified as elements influencing the effective use of gamification for learning, particularly in the field of Information Systems education.
Identifying Students' Learning Patterns in Online Learning Environments: A Literature Review
Authors: Ali Maryam Abdulsalam , Sahari Ashaari Noraidah , Mat Noor Siti Fadzilah , Zainudin Suhaila
Published: April 2022

Digital learning environments have offered new opportunities to stream educational materials such as courses, educational videos, forums and provide outcomes of the students, grades, engagement details, and learning patterns. These valuable educational data has emerged with the latest technologies and software tools to provide researchers and decision-makers with a better understanding of students' behaviours. These virtual learning environments can professionally aid struggling students by observing, learning, and identifying different learning patterns. Many researchers have discussed that even if there are instructions and helping tools within these environments, some students remain at risk of negative learning behaviours such as boredom, disengagement, and failure. Particularly when approaching complex or new educational content. Previous researchers have observed that the students exhibit high persistence levels when spending too much time on a particular task when they are learning remotely or too many tries to solve a specific task without reaching the success level. Students' persistence is identified as a prominent learning skill contributing to confirmed success while learning new education materials. Many works of literature recognised the value of persistence. They reached a fundamental fact that not all persistence is considered productive, especially when spending more time and effort without moving toward a state of mastery in learning new skills and topics. This scenario may eventually lead to frustration and disengagement; in the worst-case scenarios, the students will finally drop the course or just quit learning. By examining the most relevant literature, this paper discusses the main factors affecting students' digital learning persistence. Different models performed at each learning opportunity are observed to categorise when involvements may be arranged to best aid the learners facing learning struggles.
Influences of Learning Emotion on Learning Outcome in Online Teaching Mode
Authors: Wang Xun
Published: April 2022

Online learning becomes one of the major learning modes and ways of learners due to the comprehensive integration of Internet and artificial intelligence (AI) technology into the education field. Users who adopt online and mobile learning mode present explosive growth. Due to free of time and space limits like traditional classroom teaching and possessing of rich education video resources, online learning is attracting many learners to engage in studies independently. In the future, intelligent and individualized online education development shall pay more attention to influence factors of learners’ learning outcomes, especially learning emotion of learners, except for knowledge teaching and acceptance. In this study, a questionnaire concerning influences of learning emotion of learners on learning outcome was designed based on existing studies. Learning emotion of learners influences learning outcome through four aspects, including learning interest, learning attitude, learning belief and learning motivation. Results demonstrate that learning interest, learning attitude and learning motivations can improve learning outcomes significantly. There are significant differences of learning outcomes among different grades and the latest comprehensive assessment levels. Conclusions can provide important references for universities to make scientific reforms in online teaching mode to increase learning experiences of learners.
