In this paper we introduce two new generalized variational inequalities and we give some existence results of the solutions for these variational inequalities involving operators belonging to a recently introduced class of operators. We show by examples, that our results fail outside of this class. Further, we establish a result that may be viewed as a generalization of Minty’s theorem, that is, we show that under some circumstances the set of solutions of these variational inequalities coincide. We also show, the condition that the operators, involved in these variational inequalities, belong to the above mentioned class, is essential in obtaining this result. As application, we show that Brouwer’s fixed point theorem is an easy consequence of our results.

In this paper, we introduce the concept of tripled fixed point for nonlinear and monotone mappings in partially ordered complete metric spaces and obtain existence as well as existence and uniqueness theorems for contractive type mappings. Our results generalize and extend recent tripled fixed point theorems established by Berinde and Borcut [Berinde, V., Borcut, M., Tripled fixed point theorems for contractive type mappings in partially ordered metric spaces. Nonlinear Anal. 74 (2011) 4889–4897]. Examples to support our new results are given.
Iterates of the multidimensional Cesaro operator

The iterates of the Cesaro operator were studied recently (see Fontes, F. G. and Sol ` ´ıs, F. J., Iterating the Ces´aro operators, Proc. Amer. Math. Soc., 136 (2008), No. 6, 2147–2153) on some subsets of s(C), on (C[0, 1], C) and on C([0, ∞[, C). They proved that under suitable conditions the sequence of iterates converges to a constant function. In [Andras, Sz. and Rus, I. A., ´ Iterates of Ces`aro operators, Fixed Point Theory, 11 (2010), No. 2, 171–178] the authors gave some more general results regarding the convergence of the iterates by proving that the Cesaro operator is a contraction on a ` dense subset of (C[0, 1], B), equipped with a well chosen norm, where B is a Banach space. The convergence of iterates for some general averaging operators involving one variable functions was also investigated by Sz. Andras and I. A. Rus in [ ´ Iterates of Ces`aro operators, Fixed Point Theory, 11 (2010), No. 2, 171–178]. The aim of this paper is to prove similar results involving Cesaro operators and general averaging operators for several ` variable functions. The proofs are suggested by the characterization theorem of weakly Picard operators on an L-space (see Rus, I. A., Picard operators and applications, Sci. Math. Jpn., 58 (2003), 191–219) and the method can be applied also in the study of some singular integral equations.

In the paper [Marichal, J.-L. and Mathonet, P., A description of n-ary semigroups polynomial-derived from integral domains, Semigroup Forum, 83 (2011), No. 2, 241–249] the authors provide a complete classification of the nsemigroups, defined by polynomial functions over infinite commutative integral domains with identity (i.e., the n-semigroup structures polynomial derived from integral domains). We remark that some results from that paper can be extended for the n-semigroups polynomial-derived defined over infinite semidomains with zerosumfree element. Furthermore, in this note we give a description of (n, m)- semiring structures defined by polynomial functions over such semidomains.

Published: May 2021

The research empirically examines effect of Mergers and Acquisitions on Corporate Financial success of Quoted Insurance Companies in Nigeria. It has become expedient in the face of the drastic increase in Mergers and Acquisitions activity in recent decades and the fact that there has been very little empirical evidence of positive wealth effects and particularly the success of M&A in the insurance sector. This has arisen because most studies in Nigeria have rather focused on the banking sector. Data was obtained from Quoted Insurance Companies from 2003 to 2016 and the Regression Techniques were employed in the study. The result indicated that there exists a positive effect of M&A on Corporate Financial Performance of Insurance Companies. It revealed that a unit increase in merger led to about 4% increase in the Corporate Financial Performance of the merged firms. In effect, a unit increase in Earnings after Merger actually led to about 8% increase in the Corporate Financial Performance of the same firms. The study hereby recommend that Insurance Companies should look at issues of Claims settlement, Product Development and Branding while the National Insurance Commission (NAICOM) should look into the education of insurable clients as well as appropriate polices that would drive Insurance penetration in Nigeria.

App Store: market boundaries and Apple’s market power
Authors: Pavlova Natalia , Kurdin Alexandr , Polyakov Dmitriy
Published: May 2021

The article is based on the research in mobile applications markets. The distribution of market power in these markets depends on the ability of a digital ecosystem’s owner to control the handling of mobile applications inside the ecosystem. The degree of this control is determined by the substitutability of different application stores as necessary facilities for the access to mobile applications. The authors provide the survey-based empirical estimates of such substitutability for Apple’s mobile application store — App Store. The results of further tests for market boundaries delineation confirm the embeddedness of final users in Apple’s ecosystem in absence of feasible opportunities to change the operating system and, consequently, the application store. The findings explain the degree of Apple’s market power and provide grounds for antitrust intervention.

Modern trends characterized by increasing Russian household debt against the stagnation of real income of the population demonstrate the importance of analytical tools within the regulator. It helps identify the level of debt burden in household sector and to develop an analytical toolkit that makes it possible to reveal debt burden. The paper uses the methods of statistic and graphical analysis as well as comparative and GAP-analysis. The empirical analysis is based on data of the Federal State Statics Service and Bank of Russia over a period of 1.01.2007–1.01.2019. The study develops the methodology to create an indicator for household sector debt burden both on macro- and micro-level. Based on the methodology, we develop a new financial stability index of household sector and its calculation algorithm. We offer the evaluation method of threshold value of this index and determine its quantitative value. The findings concerning debt burden level in Russia’s household sector drawn on the basis of this indicator confirm its suitability for using as an additional diagnostic tool of Russia’s financial stability.
INTERACTION BETWEEN APPARENT AND IMPLIED AUTHORITY IN THE IMPLEMENTATION OF SUSTAINABLE BUSINESS RELATIOHSIPS
Authors: JURKEVIČIUS Vaidas , BUBLIENĖ Raimonda
Published: May 2021

Purpose – to reveal the problems of apparent and implied authority in the context of sustainable business relationships. Research methodology – the research is conducted from a comparative perspective, explaining the problems of apparent and implied authority in selected jurisdictions. Findings – authors conclude that apparent authority is the exclusive remedy available only where a link has been established between the circumstances of the principal and the reasonable belief of the third party. Implied authority cannot be equated with apparent authority, although case law often does not distinguish between these two categories. Research limitations – due to limited scope, this article does not address the ratification of unauthorised agent’s actions and the liability of falsus procurator. Practical implications – the research reveals that implied authority derives from the factual circumstances in which the agent acts and must be regarded as part of the actual authority, which presupposes that, unlike in the case of apparent authority, the implied representation does not qualify as one of the cases of unauthorised agency. Originality/Value – the significance of this study is linked to the development of reasonable rules for the application of apparent and implied authority in order to safeguard the legitimate interests of all persons involved in this complex relationship.
Binning is Sinning (Supernova Version): The Impact of Self-calibration in Cosmological Analyses with Type Ia Supernovae
Authors: Brout Dillon , Hinton Samuel R. , Scolnic Dan
Published: May 2021

Recent cosmological analyses (e.g., JLA, Pantheon) of Type Ia supernovae (SNe Ia) have propagated systematic uncertainties into a covariance matrix and either binned or smoothed the systematic uncertainty vectors in redshift space. We demonstrate that systematic error budgets of these analyses can be improved by a factor of ∼ 1.5 × with the use of unbinned and unsmoothed covariance matrices. To understand this, we employ a separate approach that simultaneously fits for cosmological parameters and additional self-calibrating scale parameters that constrain the size of each systematic. We show that the covariance-matrix approach and scale-parameter approach indeed yield equivalent results, implying that in both cases the data can self-calibrate certain systematic uncertainties, but that this ability is hindered when information is binned or smoothed in redshift space. We review the top systematic uncertainties in current analyses and find that the reduction of systematic uncertainties in the unbinned case depends on whether a systematic is solely degenerate with the cosmological model in redshift space or whether it can be described by additional correlations between supernova properties and luminosity. Furthermore, we show that the power of self-calibration increases with the size of the data set, which presents a tremendous opportunity for upcoming analyses of photometrically classified samples, like those of Legacy Survey of Space and Time (LSST) and the Nancy Grace Roman Telescope (NGRST). However, to take advantage of self-calibration in large, photometrically classified samples, we must first address the issue that binning is required in currently used photometric analysis methods.
Intraday Mid-infrared Variability of PMN J0948+0022 on 2020 April 26
Authors: Mao Lisheng
Published: May 2021

We report a new period mid-infrared variability of PMN J0948+0022 on 2020 April 26, observed by the Wide-field Infrared Survey Explore (WISE). This source faded consistently over a period of one day. The amplitude of variability is about 0.21 and 0.18 mag in the W1 (3.4 μm) and W2 (4.6 μm) bands, respectively. The intraday variability constrains the size of the mid-infrared emission region to about 5 × 10−4 pc, which is rather smaller than that of the dust torus but consistent with the base of a jet. The mid-infrared color showed a significant bluer-when-brighter trend, similar to γ-ray emitting blazars. These characteristics suggest that the mid-infrared emission was dominated by the synchrotron emission of relativistic electrons in the jet.
Looking for Astrometric Signals below 20 m s−1: A Candidate Exo-Jupiter in δ Pav
Authors: Makarov Valeri V. , Zacharias Norbert , Finch Charles T.
Published: May 2021

We use a combination of Hipparcos space mission data with the USNO dedicated ground-based astrometric program URAT-Bright designed to complement and verify Gaia results for the brightest stars in the south to estimate the small perturbations of observed proper motions caused by exoplanets. One of the 1423 bright stars in the program, δ Pav, stands out with a small proper motion difference between our long-term estimate and Gaia EDR3 value, which corresponds to a projected velocity of (−17, +13) m s−1. This difference is significant at a 0.994 confidence in the R.A. component, owing to the proximity of the star and the impressive precision of proper motions. The effect is confirmed by a comparison of long-term EDR3-Hipparcos and short-term Gaia EDR3 proper motions at a smaller velocity, but with formally absolute confidence. We surmise that the close Solar analog δ Pav harbors a long-period exoplanet similar to Jupiter.
Application of the surgical Apgar score (SAS) to predict postoperative complication(s) in the patients with traumatic brain injury: Study of single center in Indonesia
Authors: Arifin Muhammad Z. , Sendjaja Andi N. , Faried Ahmad
Published: May 2021

BACKGROUND: Traumatic brain injury (TBI) is a major health problem. Surgery in patients with TBI is associated with a high rate of complications and mortality. The surgical Apgar score (SAS) is a simple quantitative and objective intraoperative tool for predicting major post-operative complications including mortality.
AIM: Our study aimed to analyze the use of SAS as a predictor of post-operative complications in patients with TBI.
METHODS: This was a prospective cohort study at our center in RSHS, Bandung, Indonesia, throughout 2017 by assessing SAS based on calculating intraoperative estimated blood loss, lowest mean arterial pressure, and lowest heart rate for each patient with TBI, as well as the incident complications within 30 days post-operative were recorded.
RESULTS: One hundred fifty-six patients with TBI underwent surgery in 2017 with 123 patients met the inclusion criteria. Among those, 63 patients (51.2%) developed major complications with 8 patients (12.7%) experienced death. The mean SAS for patients without complication was 8.20, whereas for patients with complication was 6.11. SAS has an inverse correlation (r = –0.754) and an association (p < 0.005) with post-operative complication (s) within 30 days.
CONCLUSIONS: The SAS has an inverse correlation and an association with incidence of complications thus potentially useful as an intraoperative predictor for incident complications within 30 days post-operative care in patients with TBI.
First record of the cryptic fishes Ptereleotris calliura (Gobiidae) and Liopropoma rubre (Serranidae) from the Veracruz reef system in Mexico
Authors: Rivera-Higueras Mariana , Perez-España Horacio
Published: May 2021

Based on several in situ observations, the species Ptereleotris calliura (family Gobiidae) and Liopropoma rubre (family Serranidae) are added to the taxonomic fish inventory of the Veracruz reef system, Mexico. While P. calliura was found on sandy substratum in the lagoon, L. rubre was detected on the reef slope. With their addition, the checklist of reef fishes in the Veracruz reef system is expanded to 479 species. Given these findings, we predict that additional survey efforts (beyond visual transects) will reveal more previously unrecorded species of cryptic fishes in the Veracruz reef system.
Gauchergasilus euripedesi (Copepoda, Ergasilidae) parasitizing different species of fish from two environments in southern Brazil
Authors: Gallas Moisés , Utz Laura R. P.
Published: May 2021

The parasitic copepodGauchergasilus euripedesi(Montú, 1980) Montú & Boxshall, 2002 was described from plankton samples and specimens found in four fish species from the estuarine area of Patos Lagoon, state of Rio Grande do Sul (RS), Brazil. Later, one different fish species was reported parasitized withG. euripedesiin the same locality. Species ofAstyanaxBaird & Girard, 1854 (Astyanax henseliMelo & Buckup, 2006 andAstyanax lacustris(Lütken, 1875)) andPsalidodonEigenmann, 1911 (Psalidodon eigenmanniorum(Cope, 1894) and Psalidodon aff. fasciatus (Cuvier, 1819)) were collected in two environments (Pintada Island, municipality of Porto Alegre and Itapeva Lagoon, municipality of Terra de Areia, RS) to investigate their parasites. The copepods found in the gill arches were counted, processed, mounted in permanent slides, and photographed using light microscopy, or processed for observation in scanning electron microscopy. Specimens ofP. eigenmanniorumfrom Pintada Island,A. lacustrisand P. aff. fasciatus from Itapeva Lagoon, were parasitized byG. euripedesi, with prevalences of 29.03% (A. lacustris), 10.34% (P. eigenmanniorum), and 9.68% (P. aff. fasciatus). Measurements obtained for specimens ofG. euripedesiwere similar to those found in the literature, except for egg sacs which were larger in the specimens examined in the present study. In addition to being the first report ofG. euripedesiparasitizing species of fish (A. lacustris,P. eigenmanniorum, and P. aff. fasciatus), the results presented here also extend the known geographic distribution of the copepod species.
La cité introuvable. Saint Thomas d’Aquin et les deux cités
Authors: Lanavère Jean-Rémi
Published: May 2021

L’interprétation reçue de la pensée politique de Thomas d’Aquin la situe dans une prise de distance à l’égard de l’héritage augustinien, et en particulier vis-à-vis d’un usage politique du thème de la cité de Dieu. Afin de vérifier la pertinence d’un tel jugement, rien ne valait un examen attentif, d’une part, de tous les usages que Thomas d’Aquin fait du thème des deux cités tel qu’il se trouve présent dans la Cité de Dieu , et d’autre part de toutes les références à la Cité de Dieu qui ont une portée politique pour Thomas d’Aquin. Le résultat de ce repérage textuel est formel : une cité de Dieu à usage politique est effectivement introuvable chez Thomas d’Aquin, et la référence à la Cité de Dieu est un moyen pour Thomas d’Aquin de puiser à la source antique en matière politique, aux antipodes, donc, de toute forme d’« augustinisme politique ».
Les politiques publiques de logement en Jordanie (1965-2019)
Authors: Ababsa Myriam
Published: May 2021

Bien que la Jordanie ait été dotée très tôt d’une stratégie du logement, en 1989, ses politiques publiques de logement n’ont pas permis de produire suffisamment de logement abordable pour une population en plein essor démographique. Le locatif social est inexistant. En 2008, le gouvernement a débuté un ambitieux programme de construction de 100 000 logements en cinq ans. Mais la crise économique et le printemps arabe ont suspendu le projet, les citoyens ne parvenant pas à obtenir de prêts immobiliers. Des partenariats publics-privés sont encouragés dans les années 2000 pour produire des logements pour la classe moyenne. 18  % du stock immobilier est vide, tandis que 10  % des logements sont surpeuplés. Le tiers de la production immobilière est informelle.
Le lent et incomplet processus de territorialisation dans la Ville Nouvelle d’Ali Mendjeli : d’habitants relégués dans un agrégat de logements sociaux à l’émergence de citadins
Authors: Ahcène Lakehal , Mouhieddine Kherouatou
Published: May 2021

Il s’agit ici de retracer la genèse et l’évolution de la Ville Nouvelle d’Ali Mendjeli (à Constantine), une ville créée ex nihilo , dont la réalisation a été freinée par des blocages multiples et des difficultés – en particulier financières – récurrentes, et pour laquelle la mixité sociale n’a jamais fait partie des objectifs à atteindre. L’article tente de vérifier comment, malgré ces conditions initiales plutôt répulsives, la fabrique d’une ville et l’émergence d’une société urbaine ont été rendues possibles. Comment, en une vingtaine d’années, une ville artificielle, en chantier permanent, qui s’est construite à partir de fragments épars, témoignant d’une ségrégation voulue dès l’origine, a progressivement « pris vie » et s’est animée au point que ses habitants ont commencé à constituer une « nouvelle » société urbaine. Comment le temps long a permis l’établissement d’un rapport (en termes de pratiques et de représentations sociales), tantôt ordinaire, tantôt spécifique, entre la société et l’espace dans la ville nouvelle.
