Effective anti-corruption as a competitive advantage of a professional enterprise
Authors:   Synergy University, Alaverdov Ashot R. , Alaverdova Tatyana P. ,   Synergy University
Published: December 2021

The subject area of the article is the work of a modern organization to counter the threat of corruption from its officials. Persons Specific forms of implementing corruption threats in the commercial, financial, production, technological and personnel areas of the business entity are specified, their negative impact on market positions is determined. The thesis is argued that the degree of protection from the threat of corruption by its own persons is rightfully considered as an additional competitive advantage of any subject of professional entrepreneurship or, accordingly, its competitive disadvantage. The concept of a “workplace with a corruption component” is disclosed and their list in a modern commercial organization is specified. Personal qualities and other characteristics of a candidate for employment or an employee already in the staff are determined, which exclude the possibility of replacing such workplaces. Recommendations are formulated and argued for the introduction of four groups of HR technologies implemented within various areas of the corporate personnel management system and ensuring effective prevention or prompt identification of relevant threats in order to acquire additional competitive advantages for the subject of professional entrepreneurship. The first group of technologies is used in the process of selecting candidates for replacement of jobs with a corruption component. The purpose of their implementation is to identify individual characteristics, the presence of which calls into question both the overall loyalty of the applicant and its “anti-corruption stability.” The second group of technologies involves the prevention of corruption through the use of special tools for the economic motivation of personnel. The third group of technologies provides the possibility of both prevention and detection of the threats under consideration and involves the use of special control procedures when concluding business contracts and contracts for a large business size of a particular organization. Finally, the fourth group of technologies is used to monitor the activities of employees replacing jobs with a corruption component.
The competitive environment and directions of Russian universities competition
Authors:   Synergy University, Vasilev Artem I.
Published: December 2021

This article is devoted to the description of the competitive environment of the educational system of higher education. The directions and forms of competition of Russian universities are revealed in accordance with the constructive theory of competition. The article describes the classical theoretical directions of competition: product, industry, intersectoral, and inter-product competition. Product competition is the competition between manufacturers of interchangeable goods in the same distribution channels. It is a rivalry between competing product brands for distribution, otherwise known as trademark competition. Industry competition is the competition between producers of goods using homogeneous, interchangeable resources. In fact, this is competition for resources between producers of one sector, while there may be no product competition in distribution and sales. Inter-product competition is the competition between substitutes from different industries, that is, between representatives of different industries - manufacturers of products that satisfy the same need. Cross-industry competition is the competition of corporate brands in marketing, the general competition of all brands to attract the attention of a certain segment of consumers. The article shows that all four directions of competition appears in their forms in the activities of Russian universities. The specific forms of competition between Russian universities are revealed. Competition among universities appears in different forms: for social authority and influence; for statuses, titles, and prestige; for exclusive intellectual property, massive data sets, and computing power; for the talents of students; for the talents of teachers; for budget funding; for grant, competitive financing; for donations and endowment funds. Special attention is paid to the forms of competition within partnerships and cooperation between universities. In this form, the bargaining power is used in the distribution of value between the participants in the partnership.

This article is devoted to competitive competencies in entrepreneurship as the results of training in the programs of entrepreneurial education in the master’s program. This unique area of expertise is critical to success in entrepreneurship, but is still not enough researched and classified. Modern methods of teaching entrepreneurship are based on a competence-based approach to the study of professional entrepreneurial competencies, the purpose of which is to consistently master a certain set of necessary entrepreneurial competencies. The article examines the existing approaches to competition when considering the classification of competitive competencies related to entrepreneurship, and also determines the place of competitive competencies in the composition of entrepreneurial competencies. The author’s classification of professionally significant entrepreneurial competencies for various levels of higher education (bachelor’s and master’s degrees) is given, which should be structured into professional, general professional, universal competencies, as well as other competencies (industry, regional, etc.). The features of teaching entrepreneurial competencies at the master’s level are determined. The unique experience of studying and development of entrepreneurial competencies on the graduate level and appropriate methods to effectively develop competitive competence in two stages is described: first, to develop core competencies, namely: competence in various types, methods and styles of competitive actions; competence in competitive positioning; competence in the management of competitive actions; competence in compliance with antitrust laws; competencies in the selection and management of competitive status, and then specific competencies in the development and implementation of competitive strategy and tactics of competition.

Machiavellian Sebagai Variabel Moderasi Pada Pengaruh Audit Fee Terhadap Disfungsional Auditor
Authors: Suprapto Fitria Magdalena
Published: December 2021

Penelitian ini bertujuan untuk menguji pengaruh machiavellian sebagai variabel moderasi pada audit fee terhadap disfungsional auditor. Metode penelitian yang digunakan adalah kuantitatif dengan sumber data primer melalui pengumpulan data kuesioner yang disebarkan dengan mempertimbangkan beberapa kriteria tertentu atau purposive sampling. Dari 100 responden yang disebar, sebanyak 66 yang memenuhi kriteria sebagai sampel dan dapat diolah menggunakan regresi linear dan moderated regression analysis. Hasil penelitian menunjukkan bahwa variabel audit fee berpengaruh negatif terhadap disfungsional auditor karena fee atas pekerjaan audit yang dinilai terlalu rendah menyebabkan auditor menyelesaikan pekerjaan yang terlalu cepat. Tekanan yang dialami auditor dari manajemen tingkat atas ke bawah ini akan mendorong perilaku tereduksinya kualitas audit atau perilaku disfungsional auditor, sementara machiavellian tidak mampu memoderasi audit fee terhadap disfungsional auditor karena tidak adanya komitmen dalam menjaga integritas akan menaikkan perilaku disfungsional auditor. Penelitian ini berkontribusi pada perusahaan dan regulator karena atas audit fee yang dikeluarkan akan menentukan tindakan disfungsional yang dilakukan oleh auditor, sehingga regulator dapat mempertimbangkan regulasi yang adil atas penentuan batasan audit fee.

The Distribution of Europium over the Surface of 21 Com
Authors: Monier Richard
Published: December 2021

Comparison of optical high resolution high signal-to-noise ELODIE spectra of 21 Com taken in 2004 April and separated by about half of the 2 days rotational period, reveals variations of the Eu ii resonance and low excitation lines between rotational phases 0.94 and 0.48. All Eu ii lines are consistently stronger at phase 0.94. The synthesis of these Eu ii lines yields disk-averaged estimates of the abundances of europium: about 50 times solar at phase 0.94 and 25 times solar at phase 0.48.
A New Classification Model for the ZTF Catalog of Periodic Variable Stars
Authors: Cheung Siu-Hei , Villar V. Ashley , Chan Ho-Sang , Ho Shirley
Published: December 2021

Using the second data release from the Zwicky Transient Facility (ZTF), Chen et al. created a ZTF Catalog of Periodic Variable Stars (ZTF CPVS) of 781,602 periodic variables stars (PVSs) with 11 class labels. Here, we provide a new classification model of PVSs in the ZTF CPVS using a convolutional variational autoencoder and hierarchical random forest. We cross-match the sky-coordinate of PVSs in the ZTF CPVS with those presented in the SIMBAD catalog. We identify non-stellar objects that are not previously classified, including extragalactic objects such as Quasi-Stellar Objects, Active Galactic Nuclei, supernovae and planetary nebulae. We then create a new labeled training set with 13 classes in two levels. We obtain a reasonable level of completeness (≳90%) for certain classes of PVSs, although we have poorer completeness in other classes (∼40% in some cases). Our new labels for the ZTF CPVS are available via Zenodo.
The Infrared Complex Refractive Index of Amorphous Ammonia Ice at 40 K (1.43–22.73 μm) and Its Relevance to Outer Solar System Bodies
Authors: Roser Joseph E. , Ricca Alessandra , Cartwright Richard J. , Dalle Ore Cristina , Cruikshank Dale P.
Published: December 2021

A near-IR absorption band at 2.2 μm linked to ammonia-containing ice has been detected on icy bodies throughout the solar system and appears in the extensive volume of data for Pluto and Charon returned by New Horizons. This band is an important clue for understanding the abundance of ammonia and ammoniated compounds on the surface of outer solar system bodies and requires new laboratory data for its full analysis. To satisfy this data need, the complex refractive index of amorphous ammonia ice was calculated from experimental infrared transmission spectra with ice deposition and measurements conducted at 40 K, a characteristic surface temperature for outer solar system bodies. The measured imaginary part of the complex refractive index and associated band strength calculations are generally larger than prior published values for amorphous ammonia ice at 30 K. The complex refractive index for amorphous ammonia at 40 K computed in the mid-infrared region (2.5–22.73 μm) will also be valuable for interpreting observations of both solar system and astrophysical sources anticipated with the Near InfraRed Spectrograph and Mid-Infrared Instrument on the James Webb Space Telescope.

The impacts of COVID -19 pandemic have been quite significant on healthcare providers. I was particularly challenging for those in Low and Middle-Income Countries including Sudan . Unfortunately, the pandemic has hit Sudan on extremely difficult time for the country and its people. The country was coming out of long-brutal and devastating dictatorship and transitioning to new democracy with civilian leadership. In addition to the pandemic related issues, trying to rebuild the health system during socioeconomic crisis, healthcare providers  in the country were challenged personally and professionally. These challenges include the stress of working in under-resourced settings with limited access to personal-protection equipment and testing kits raised the fear of contracting the virus and spreading it to their families. The professional, social, and personal life of healthcare providers have been dramatically changed by the ongoing pandemic, however, they are heroically accepting this change in a hope that, this will save the life of many more people. Nevertheless, their fights and sacrifices should at least be rewarded by governments and communities altogether strictly enforce the implementation of other preventive measures including vaccination, face masking, and social distancing and get all protected. We should all understand that, unless we are all protected no one is protected, so all must adapt to the new norm of life and collaborate not only on ending this pandemic but to prevent similar ones in the future.

Novel coronavirus infections 2019 (COVID-19) associated hyperinflammatory syndromes are well-defined clinical conditions and have a potential risk for severe infection. Hemophagocytic lymphohistiocytosis (HLH), a rare type of acute progressive hyperinflammatory syndrome, has been reported in a limited number of COVID-19 cases. In this article, we aimed to present a patient with HLH secondary to COVID-19 diagnosed by bone marrow biopsy, and to summarize and review HLH cases associated with COVID-19 in the literature.

A 47-year-old male patient presented with complaints of fever, cough, abdominal discomfort, and nausea-vomiting. He had recovered from COVID-19 a month ago and was readmitted to the hospital due to the re-appearance of clinical symptoms after a two-week interval. The patient was diagnosed with HLH secondary to COVID-19 on sixth day of admission and fully recovered with systemic pulse steroid, intravenous immunoglobulin, and plasma exchange therapy. Analysis of literature searches revealed that 22 cases were definitely diagnosed with COVID-19-associated HLH, 16 of them were male. They had been treated with different anti-cytokine drugs, of which nine had died. The increasing number of HLH cases, which have high mortality rates, shows the importance of hyperinflammatory syndromes in COVID-19 patients. Some patients may experience hemophagocytosis in the late period of COVID-19, even while in recovery. Increased awareness and early treatment for HLH triggered by COVID-19 can be a life-saving effort for reducing mortality in severe COVID-19 cases.
Acceptance and barriers of COVID-19 vaccination among people with chronic diseases in Saudi Arabia

Published: December 2021

Introduction: Coronavirus Disease 2019 is a life-threatening disease, especially for people suffering from chronic diseases. As the vaccine is considered an essential tool to confront pandemics, many international medical institutions have developed vaccines. Countries around the world started immunizing their citizens. This study aims to assess the acceptance and barriers of COVID-19 vaccine uptake among Saudi Arabian people who suffer from chronic diseases.

Methodology: In February-March 2021, a cross-sectional study of Saudi Arabian people who have chronic diseases was undertaken. It was based on an Arabic self-administered online questionnaire and used a convenience sampling technique. 310 people were invited. The response rate was 97%.

Results: 51.95% of the participants agreed to take the COVID-19 vaccine, 33.5% were unsure about being vaccinated, and 14.5% refused. The most frequent concerns between participants and receiving the vaccine were about the side effects and the perceived misconception that following preventative measures is enough to protect against the virus. Significant associations between age, education, and occupation with acceptance rate were found (p < 0.05).

Conclusions: Although a higher acceptance for the targeted group was expected, the participants showed a moderate acceptance of the COVID-19 vaccine. Addressing the barriers in the current study regarding vaccine uptake and focusing on building trust in the safety and efficacy of the vaccine will aid in hesitancy and resistance toward the vaccine, specifically if these measures were undertaken by an authority such as the Saudi Ministry of Health.

Published: December 2021

Antihyperglycemic activity of Ipomoea batatas (L.) leaves has been studied for years. As many naturally found varieties of such plant species have been used as herbal medicines, there is a need to establish a fingerprint biomarker standardization method. Our research combined TLC fingerprints and chemometric analysis to determine biomarkers in leaf ethanol extract of Ipomoea batatas (L.) (EIBL). We predicted the main constituents of anthocyanin glycosides and their acylated derivates in the leaf ethanol extract of such plants using ESI-MS. The EIBL that contained identified biomarkers has succeeded in providing an antihyperglycemic effect in experimental using STZ-induced rats. This study also found a linear correlation between doses of flavonoid derivates as antioxidant agents with their antihyperglycemic activities. Therefore, this biomarker information can be used as a model to predict the dose-responses of the antihyperglycemic activities produced by other leaf ethanol extracts of I. batatas.
Comparison of efficacies of full and abbreviated cascade impactors in aerosol characterization of nebulized salbutamol sulfate produced by a jet nebulizer
Authors: Nimmano Nattika , Mohari Safura Binti Mohd
Published: December 2021

The properties of aerosols generated from salbutamol sulfate solution (1 mg/mL) using an air-jet nebulizer were evaluated using Next Generation Impactor (NGI), a full cascade impactor, and Fast Screening Impactor (FSI), an abbreviated impactor measurement (AIM). Both impactors were operated under the same experimental conditions. The samples were recovered and assayed using validated high performance liquid chromatography (HPLC). The study investigated AIM-Human Respiratory Tract (HRT) concept by comparing key parameters of aerosolization i.e. fine particle dose (FPD) and fine particle fraction (FPF) measured using FSI, with NGI as baseline. The results showed that FSI yielded different but comparable values for FPD and FPF, indicating that it is alternative impactor to NGI. Despite the fact that FSI could not replace NGI, it may be used as an alternative impactor for simple and rapid aerosol characterization of formulations in some pharmaceutical development and quality control processes.
Comment les Romains se représentaient leur Empire. L’apport des cursus sénatoriaux (époques républicaine et julio-claudienne)
Authors: Hurlet Frédéric
Published: December 2021

Étudié la plupart du temps dans une perspective chronologique et prosopographique, le contenu des cursus sénatoriaux d’époque républicaine et julio-claudienne peut également aider à mieux comprendre le phénomène de territorialisation de l’Empire romain. L’usage épigraphique en vertu duquel le nom de la province gouvernée n’est pas indiqué dans les inscriptions datées de l’époque républicaine signifie que l’élément déterminant était non pas le nom de la province, mais le statut sur lequel se fondait l’intervention de tel dignitaire dans la province en question. On en déduira que l’ imperium était alors perçu prioritairement comme un pouvoir, et non comme un espace. Un changement se fit jour à l’époque augustéenne, quand une nouvelle pratique épigraphique, consistant à dénommer les provinces gouvernées, coexista avec l’ancienne. Il faut y voir un effet de la réforme de janvier 27 av. J.-C., qui contribua à faire de l’Empire un espace bien délimité en créant des provinces fixes et en les hiérarchisant. La territorialisation de l’Empire romain fut toutefois un processus de longue durée qui s’étendit tout au long de la première moitié du i er  siècle apr. J.-C. Le terme de cette période de transition est le Principat de Claude, à l’issue duquel les noms des provinces furent systématiquement mentionnés dans les cursus sénatoriaux provenant de Rome et d’Italie.

Pour survivre ensemble face aux traumatismes familiaux, frères et sœurs nouent des alliances et des pactes, plus ou moins élaborés, plus ou moins salvateurs, et parfois pathogènes. À travers l’étude d’un roman, de deux contes, et d’un film d’animation, les auteurs tentent d’identifier les défaillances parentales et les mécanismes d’identification en jeu au sein des fratries.
Pourquoi le Stabat Mater de Pergolèse est-il si émouvant ?
Authors: Chomy Lucien
Published: December 2021

Qu’éprouve-t-on à l’écouter ? L’auteur mène sa réflexion en partant de l’émotion, il suit les pistes paradoxales qui s’offrent à sa recherche, sur un mode associatif. Un culte millénaire prend naissance de la silhouette de Marie entraperçue au pied de la croix. La vie bouleversée du moine poète Jacopone da Todi dans son époque et dans son ambiguïté. Des patients qui questionnent les certitudes. La reprise par la musique d’une intuition perdue par la poésie. La fièvre de Pergolèse, ses voix de castrat et son enthousiasme créatif, jusqu’à la mort. L’écoute musicale procure une émotion immédiate, évidente mais elle est pourtant une expérience multiple porteuse d’une pensée complexe à exprimer. L’écoute du psychanalyste peut-elle s’en inspirer ?

Published: December 2021

À partir de l’analyse du cas d’une artiste issue d’une fratrie de 4 filles, cet article met en exergue les retentissements du choix du métier d’artiste dans la dynamique familiale et plus particulièrement dans l’organisation du lien sororal. Via l’analyse d’un entretien de recherche, d’un questionnaire avec des questions ouvertes et celle des œuvres, les rapports entre les objets artistiques et l’objet fraternel sont interrogés. Ceci ouvre sur une discussion concernant le traitement que reçoit le fantasme d’indifférenciation, la rivalité et la relation d’objet dans une fratrie de sœurs. À partir des travaux de R. Kaës, R. Jaïtin, R. Roussillon et d’autres psychanalystes groupalistes, les auteurs proposent une approche des processus de production artistique dans la gestion du complexe fraternel.
Métaphoriser en cothérapie : une voie vers le holding onirique
Authors: Sanahuja Maria de la Almudena , Naimi Marie
Published: December 2021

À partir du constat de dimensions symptomatiques mortifères présentées par la rencontre avec une famille reçue en thérapie, nous souhaitons mettre le projecteur sur les mécanismes psychiques inconscients qui sous-tendent le néo-groupe (Granjon, 1987, as cited in Granjon, 2001). Nous montrerons l’impact sur le cadre thérapeutique des failles narcissiques d’une famille au fonctionnement opératoire et évoquerons la paralysie des thérapeutes dans leur capacité de holding onirique familial. Pour ce faire, nous explorerons les éléments contre et inter-transférentiels et l’évolution du contenant-contenu psychique du néo-groupe face à l’effacement progressif des symptômes familiaux et à l’émergence de la pulsionnalité. Nous aborderons ainsi la création d’un jeu de « co-métaphorisation » entre les thérapeutes, l’image de la « cocotte-minute » en étant une représentation, qui telle une stratégie permettrait la survivance de la capacité de rêverie mise à mal et éviterait l’explosion agressive ou l’effondrement dépressif.

« Unschooling » et Accompagnement des « apprentissages Autonomes » : une pédagogie radicale ou un au-delà de la pédagogie ?
Authors: Nordmann Jean-François
Published: December 2021

Appuyé sur une enquête de terrain menée en 2019-2020 dans le cadre du projet ANR « SociogrIEF – Une sociographie inédite de l’instruction en famille » et sur un corpus de plus d’une trentaine d’entretiens approfondis avec des parents «  unschoolers  », l’article cherche à rendre compte du «  unschooling  » (ou accompagnement des «  apprentissages autonomes  » de l’enfant) en montrant qu’il ne rompt pas seulement avec les programmes et les modalités pédagogiques standard de l’École, mais aussi avec toute forme de contrainte éducative, directe (par prescriptions et directives) ou indirecte (par incitations et attentes, recours à la médiation de dispositifs, etc.). À cet égard, le unschooling apparaît comme étant autre chose qu’une variété de pédagogie alternative radicale : on peut y voir un au-delà de la pédagogie, qui vient rompre avec toute entreprise – et même avec toute intention préalable – de mettre l’enfant sur le chemin des apprentissages et a fortiori d’apprentissages pré-définis supposés indispensables à son instruction et à son éducation. Éclairant ce point, on avance l’hypothèse d’un noyau du unschooling consistant, au-delà des modalités singulières d’accompagnement des « apprentissages autonomes », dans l’instauration de relations « proximales » en premier lieu avec l’enfant, mais aussi, au-delà, avec les autres (conjoint·e, amis, voisins, collègues…) ainsi qu’avec soi-même. Le unschooling apparaît dès lors comme le choix d’un mode de vie et non pas seulement d’une façon d’élever son (ou ses) enfant(s). Et ce mode de vie vient mettre en question non seulement nos représentations ordinaires de l’évidence du bien-fondé et du besoin collectif d’École, mais aussi nos conceptions mêmes des finalités de l’éducation, scolaire aussi bien que parentale, avec la visée, sur fond de pessimisme anthropologique, d’une éducation à la contrainte et à l’acceptation rationnelle de la contrainte.

The aim of this paper is to study the existence of stable standing waves for the following nonlinear Schrödinger type equation with mixed power-type and Choquard-type nonlinearities

   \begin{document}$ i\partial_t \psi+\Delta \psi+\lambda | \psi|^q \psi+\frac{1}{|x|^\alpha}\left(\int_{\mathbb{R}^N}\frac{| \psi|^p}{|x-y|^\mu|y|^\alpha}dy\right)| \psi|^{p-2} \psi = 0, $\end{document}

where $ N\geq3 $, $ 0 < \mu < N $, $ \lambda > 0 $, $ \alpha\geq0 $, $ 2\alpha+\mu\leq{N} $, $ 0 < q < \frac{4}{N} $ and $ 2-\frac{2\alpha+\mu}{N} < p < \frac{2N-2\alpha-\mu}{N-2} $. We firstly obtain the best constant of a generalized Gagliardo-Nirenberg inequality, and then we prove the existence and orbital stability of standing waves in the $ L^2 $-subcritical, $ L^2 $-critical and $ L^2 $-supercritical cases by the concentration compactness principle in a systematic way.

Many mathematicians have studied degenerate versions of some special polynomials and numbers that can take into account the surrounding environment or a person's psychological burden in recent years, and they've discovered some interesting results. Furthermore, one of the most important approaches for finding the combinatorial identities for the degenerate version of special numbers and polynomials is the umbral calculus. The Catalan numbers and the Daehee numbers play important role in connecting relationship between special numbers.

In this paper, we first define the degenerate Catalan-Daehee numbers and polynomials and aim to study the relation between well-known special polynomials and degenerate Catalan-Daehee polynomials of order $ r $ as one of the generalizations of the degenerate Catalan-Daehee polynomials by using the degenerate Sheffer sequences. Some of them include the degenerate and other special polynomials and numbers such as the degenerate falling factorials, the degenerate Bernoulli polynomials and numbers of order $ r $, the degenerate Euler polynomials and numbers of order $ r $, the degenerate Daehee polynomials of order $ r $, the degenerate Bell polynomials, and so on.

Soft set has limitation for the consideration of disjoint attribute-valued sets corresponding to distinct attributes whereas hypersoft set, an extension of soft set, fully addresses this scarcity by replacing the approximate function of soft sets with multi-argument approximate function. Some structures (i.e., possibility fuzzy soft set, possibility intuitionistic fuzzy soft set) exist in literature in which a possibility of each element in the universe is attached with the parameterization of fuzzy sets and intuitionistic fuzzy sets while defining fuzzy soft set and intuitionistic fuzzy soft set respectively. This study aims to generalize the existing structure (i.e., possibility intuitionistic fuzzy soft set) and to make it adequate for multi-argument approximate function. Therefore, firstly, the elementary notion of possibility intuitionistic fuzzy hypersoft set is developed and some of its elementary properties i.e., subset, null set, absolute set and complement, are discussed with numerical examples. Secondly, its set-theoretic operations i.e., union, intersection, AND, OR and relevant laws are investigated with the help of numerical examples, matrix and graphical representations. Moreover, algorithms based on AND/OR operations are proposed and are elaborated with illustrative examples. Lastly, similarity measure between two possibility intuitionistic fuzzy hypersoft sets is characterized with the help of example. This concept of similarity measure is successfully applied in decision making to judge the eligibility of a candidate for an appropriate job. The proposed similarity formulation is compared with the relevant existing models and validity of the generalization of the proposed structure is discussed.

In this paper a preliminary mathematical model is proposed, by means of a system of ordinary differential equations, for the growth of a species. In this case, the species does not interact with another species and is divided into two stages, those that have or have not reached reproductive maturity, with natural and control mortality for both stages. When performing a qualitative analysis to determine conditions in the parameters that allow the extinction or preservation of the species, a modification is made to the model when only control is assumed for each of the stages if the number of species in that stage is above a critical value. These studies are carried out by bifurcation analysis with respect to two parameters: control for each stage and their critical values. It is concluded that for certain conditions in their parameters, the dynamics in each of the controlled stages converge to their critical values.

A mathematical model of tumor-immune system interactions with an oncolytic virus therapy for which the immune system plays a twofold role against cancer cells is derived. The immune cells can kill cancer cells but can also eliminate viruses from the therapy. In addition, immune cells can either be stimulated to proliferate or be impaired to reduce their growth by tumor cells. It is shown that if the tumor killing rate by immune cells is above a critical value, the tumor can be eradicated for all sizes, where the critical killing rate depends on whether the immune system is immunosuppressive or proliferative. For a reduced tumor killing rate with an immunosuppressive immune system, that bistability exists in a large parameter space follows from our numerical bifurcation study. Depending on the tumor size, the tumor can either be eradicated or be reduced to a size less than its carrying capacity. However, reducing the viral killing rate by immune cells always increases the effectiveness of the viral therapy. This reduction may be achieved by manipulating certain genes of viruses via genetic engineering or by chemical modification of viral coat proteins to avoid detection by the immune cells.
Etnificación, desahucio por impago de alquileres y desplazamiento residencial en una ciudad turística insular (Las Palmas de Gran Canaria - España)

Las Palmas de Gran Canaria (Canarias) es una capital insular que, dada su especialización urbano-turística, atrae visitantes, turistas y migrantes extranjeros. En el cambio de siglo, durante el periodo de expansión económica, se incrementaron los flujos de inmigración laboral y afectaron, especialmente, al espacio central de la ciudad y al entorno de su área litoral de ocio. Sin embargo, a partir de la crisis económica del año 2008 y posteriores, estos espacios centrales, que habían constituido las áreas preferentes de residencia de la población extranjera, vieron multiplicarse los desahucios por el impago de rentas. Con el proceso de recuperación económica, desde 2014, esta tendencia se ha mantenido. Este trabajo pretende, en primer lugar, analizar la relación espacial que parece existir entre la presencia de población nacida en el extranjero y los procesos de desahucio por impago de alquileres entre 2008 y 2017. En segundo lugar, estudiar el desplazamiento residencial de este colectivo, que se produce en paralelo al incremento de los precios y lanzamientos de las viviendas en alquiler y, por último, indagar en el proceso de sustitución residencial por origen que parece acompañarlo. La combinación de datos que proporcionan las Estadísticas del Padrón Continuo, sobre población nacida en el extranjero, y el Registro del Servicio Común de Notificaciones y Embargos de Las Palmas de Gran Canaria, sobre desahucios, nos ha permitido realizar un análisis cartográfico y estadístico con estos propósitos.
Regret Averse Opinion Aggregation
Authors: Elkin Lee
Published: December 2021

It is often suggested that when opinions differ among individuals in a group, the opinions should be aggregated to form a compromise. This paper compares two approaches to aggregating opinions, linear pooling and what I call opinion agglomeration. In evaluating both strategies, I propose a pragmatic criterion, No Regrets, entailing that an aggregation strategy should prevent groups from buying and selling bets on events at prices regretted by their members. I show that only opinion agglomeration is able to satisfy the demand. I then proceed to give normative and empirical arguments in support of the pragmatic criterion for opinion aggregation, and that ultimately favor opinion agglomeration.
Notas e reflexões sobre percursos epistemológicos nas Ciências da Comunicação
Authors: Maia Lídia Raquel Herculano , Maia Jadson
Published: December 2021

As ciências da comunicação formam um campo de conhecimento relativamente novo e em constante construção. Pensar a constituição desse campo e suas raízes epistemológicas é o objetivo principal do presente texto. Para tanto, parte-se de uma discussão sobre as noções gerais e os principais aspectos envolvidos em estudos de caráter epistemológico; depois, são analisados os trabalhos de autores como Alsina (1989) e Wolf (1995), que se esforçam em traçar uma epistemologia da comunicação, com diferentes enfoques; e, por fim, aponta-se brevemente as contribuições mais recentes de alguns autores brasileiros e latino-americanos para os estudos em comunicação. Concluindo-se que a sofisticação da recepção é uma questão transversal às teorias aqui perfiladas e a sua crescente coparticipação nos processos deve ser levada a cabo no itinerário contemporâneo da pesquisa.
Toward a Paradigm to Distinguish Distinct Functions of FOXP3+ Regulatory T Cells
Authors: Weinberg Samuel E , Singer Benjamin D
Published: December 2021

FOXP3+ regulatory T (Treg) cells are a unique subset of CD4+ T cells that classically function as master regulators of immune homeostasis. Besides this canonical suppressive role, which is required to maintain self-tolerance, a growing body of literature has identified Treg cells as critical orchestrators of tissue protection during acute stress and as effector cells that drive repair following tissue injury. Despite substantial interest in these distinct roles, the field has struggled to disentangle Treg cell suppressive functions from those that promote tissue defense and repair. In this article, we will examine the literature in the context of specific physiologic settings, contrasting the suppressive function of Treg cells with their emerging roles in promoting tissue homeostasis and tissue repair. Further, we will discuss a new paradigm differentiating tissue defense from tissue repair—a paradigm needed to translate Treg cell–based therapies to the clinic.

SAMHD1 is a potent HIV-1 restriction factor that blocks reverse transcription in monocytes, dendritic cells and resting CD4+ T cells by decreasing intracellular dNTP pools. However, SAMHD1 may diminish innate immune sensing and Ag presentation, resulting in a weaker adaptive immune response. To date, the role of SAMHD1 on antiretroviral immunity remains unclear, as mouse SAMHD1 had no impact on murine retrovirus replication in prior in vivo studies. Here, we show that SAMHD1 significantly inhibits acute Friend retrovirus infection in mice. Pretreatment with LPS, a significant driver of inflammation during HIV-1 infection, further unmasked a role for SAMHD1 in influencing immune responses. LPS treatment in vivo doubled the intracellular dNTP levels in immune compartments of SAMHD1 knockout but not wild-type mice. SAMHD1 knockout mice exhibited higher plasma infectious viremia and proviral DNA loads than wild-type mice at 7 d postinfection (dpi), and proviral loads inversely correlated with a stronger CD8+ T cell response. SAMHD1 deficiency was also associated with weaker NK, CD4+ T and CD8+ T cell responses by 14 dpi and weaker neutralizing Ab responses by 28 dpi. Intriguingly, SAMHD1 influenced these cell-mediated immune (14 dpi) and neutralizing Ab (28 dpi) responses in male but not female mice. Our findings formally demonstrate SAMHD1 as an antiretroviral factor in vivo that could promote adaptive immune responses in a sex-dependent manner. The requirement for LPS to unravel the SAMHD1 immunological phenotype suggests that comorbidities associated with a “leaky” gut barrier may influence the antiviral function of SAMHD1 in vivo.
