MANIFESTATION OF EVIDENTIALITY IN KARACHAY-BALKAR LANGUAGE
Authors: Кошева Астра Шагабановна
Published: November 2020

В статье изложены промежуточные результаты исследования средств выражения эвиденциальности и миративности в одном из тюркских языков Северного Кавказа (в карачаево-балкарском языке). В центре нашего внимания - одна из объемных языковых универсалий и ее воплощение в формах глагольных наклонений. Цель исследования - выявление и описание грамматических средств репрезентации эвиденциальных значений в исследуемом языке. Актуальность обусловлена отсутствием специальных исследований категории эвиденциальности в карачаево-балкарском языке. Категория эвиденциальности в исследуемом языке впервые описывается как языковое явление с использованием современных теоретических подходов. Основными методами являются описательный метод, метод контекстуального анализа и традиционный семасиологический подход «от формы к содержанию». В качестве источников фактического материала были использованы произведения карачаево-балкарской художественной прозы, частично фольклорные тексты и разговорная речь. Анализ практического материала позволил выделить в исследуемом языке несколько разновидностей эвиденциальных высказываний, среди которых наиболее типичными эвиденциальными значениями являются ‘очевидность / неочевидность’, ‘неожиданное обнаружение / изумление’, ‘пересказ / цитирование’. Результаты исследования могут быть использованы для создания функционального синтаксиса исследуемого языка, а также при исследовании эвиденциальности в родственных языках.

The article presents the intermediate results of the study of the means of manifestation of evidentiality and mirativity in one of the Turkic languages of the North Caucasus (in the Karachay-Balkar language). We focus on one of the voluminous linguistic universals and its embodiment in the forms of verbal moods. The purpose of the study is to identify and describe the grammatical means of manifestation of evidential meanings in the studied language. The relevance is due to the lack of special studies of the category of evidentiality in the Karachay-Balkar language. The category of evidentiality in the studied language is described for the first time as a linguistic phenomenon using modern theoretical approaches. The main methods are the descriptive method, the method of contextual analysis and the traditional semasiological approach «from the form to the content». The sources of factual material were the works of Karachay-Balkar fiction, partly folklore texts and colloquial speech. The analysis of the practical material made it possible to single out several types of evidential statements in the studied language, among which the most typical evidential meanings are ‘obvious / non-obvious’, ‘unexpected discovery / amazement’, ’retelling / citation’. The study results can be used to create a functional syntax of the studied language, as well as in the study of evidentiality in related languages.

Published: November 2020

Современная практика подготовки специалистов сферы культуры и искусства характеризуется определенными требованиями к студентам, к их профессиональным компетенциям, одна из которых - способность сохранять и популяризировать культурные ценности, в том числе фольклор и народное художественное творчество. Целью статьи является обоснование основных критериев, определяющих эффективную подготовку будущих руководителей хореографических любительских коллективов к сценической интерпретации чувашского народного танца. Термин «критерии» используется в данной статье для описания признаков, на основании которых можно судить о наличии или отсутствии у студентов знаний, умений и личностных качеств, необходимых для сценической интерпретации чувашского народного танца. Для определения критериев проанализирован чувашский народный танец с позиции его сценичности. Подробно рассматриваются следующие специфические черты: массовая форма исполнения, обусловившая бытование определенной хореографии, ее организационных и композиционных решений; зрелищность, исходящая из коммуникативной природы народного танца; условность языка танца, проявляющаяся в исторически сформированных характерных элементах его лексики; образность, отражающая самобытный характер чувашского народа. Перечисляются знания, умения и навыки, необходимые будущим руководителям хореографических любительских коллективов для сценической интерпретации чувашского народного танца.

The current training practice of cultural and an art sphere specialist is characterized by specific requirements for students and their professional competences. The ability to preserve and popularize cultural values, including folklore and folk art, is one of these requirements. The purpose of this article is to substantiate the main criteria of effective training of future amateur choreographic group leaders for stage interpretation of the Chuvash folk dance. In this article, the term «criteria» describes the features by which one can evaluate students’ knowledge, skills and personality traits needed for the stage interpretation of the Chuvash folk dance. These criteria are determined by the analysis of theatrical effectiveness of the Chuvash folk dances. In the course of analysis, the following specific features of theatrical effectiveness are considered in detail: participation of large numbers of people in performance, determining the existence of a certain choreography, organizational and compositional decisions; the visual appeal, emanating from the communicative nature of folk dance; the symbolism of dance manifested in historically formed characteristic elements of its language; the image reflecting distinctive character of the Chuvash people. The article lists the knowledge and skills needed by future leaders of amateur choreographic groups for stage interpretation of the Chuvash folk dance.
Obstructions for Symplectic Lie Algebroids
Authors:   Universit&, Klaasse Ralph L. ,   #233,   libre de Bruxelles, Belgium
Published: November 2020

Several types of generically-nondegenerate Poisson structures can be effectively studied as symplectic structures on naturally associated Lie algebroids. Relevant examples of this phenomenon include log-, elliptic, bk-, scattering and elliptic-log Poisson structures. In this paper we discuss topological obstructions to the existence of such Poisson structures, obtained through the characteristic classes of their associated symplectic Lie algebroids. In particular we obtain the full obstructions for surfaces to carry such Poisson structures.
Limiting Spectral Resolution of a Reflection Grating Made via Electron-beam Lithography
Authors: DeRoo Casey T. , Termini Jared , Grisé Fabien , McEntaffer Randall L. , Donovan Benjamin D. , Eichfeld Chad
Published: November 2020

Gratings enable dispersive spectroscopy from the X-ray to the optical, and feature prominently in proposed flagships and SmallSats alike. The exacting performance requirements of these future missions necessitate assessing whether the present state-of-the-art in grating manufacture will limit spectrometer performance. In this work, we manufacture a 1.5 mm thick, 1000 nm period (1000 gr mm−1) flat grating using electron-beam lithography (EBL), a promising lithographic technique for patterning gratings for future astronomical observatories. We assess the limiting spectral resolution of this grating by interferometrically measuring the diffracted wavefronts produced in ± first order. Our measurements show this grating has a performance of at least R ∼ 14,600, and that our assessment is bounded by the error of our interferometric measurement. The impact of EBL stitching error on grating performance is quantified, and a path to measuring the period error of customized, curved gratings is presented.
Near-infrared Spectroscopy of CK Vulpeculae: Revealing a Remarkably Powerful Blast from the Past

CK Vulpeculae (CK Vul), which erupted in AD 1670–71, was long considered to be a nova outburst; however, recent observations have required that alternative scenarios be considered. Long-slit infrared spectroscopy of a forbidden line of iron reported here has revealed high line-of-sight velocities (∼±900 km s−1) of the ansae at the tips of the bipolar lobes imaged in Hα in 2010. The deprojected velocities of the tips are approximately ±2130 km s−1 assuming the previously derived inclination angle of 65° for the axis of cylindrical symmetry of the bipolar nebula. Such high velocities are in stark contrast to previous reports of much lower expansion velocities in CK Vul. Based on the deprojected velocities of the tips and their angular expansion measured over a 10 yr baseline, we derive a revised estimate, with estimated uncertainties, of

kpc for the distance to CK Vul. This implies that the absolute visual magnitude at the peak of the 1670 explosion was

, indicating that the 1670 event was far more luminous than previous estimates and brighter than any classical nova or any Galactic stellar merger. We propose that CK Vul belongs to the class of intermediate-luminosity optical transients (ILOTs), objects which bridge the luminosity gap between novae and supernovae. While eruptions in lower luminosity ILOTs are attributed to merger events, the origin of the highly luminous ILOT outbursts is currently not known.
Investigating the Hubble Constant Tension: Two Numbers in the Standard Cosmological Model
Authors: Lin Weikang , Mack Katherine J. , Hou Liqiang
Published: November 2020

The current Hubble constant tension is usually presented by comparing constraints on H
0 only. However, the postrecombination background cosmic evolution is determined by two parameters in the standard ΛCDM model, the Hubble constant (H
0) and today’s matter energy fraction (Ωm). If we therefore compare all constraints individually in the H
0–Ωm plane, (1) various constraints can be treated as independently as possible, (2) single-sided constraints are easier to consider, (3) compatibility among different constraints can be viewed in a more robust way, (4) the model dependence of each constraint is clear, and (5) whether or not a nonstandard model is able to reconcile all constraints in tension can be seen more effectively. We perform a systematic comparison of different constraints in the H
0–Ωm space based on a flat ΛCDM model, treating them as separately as possible. Constraints along different degeneracy directions consistently overlap in one region of the space, with the local measurement from Cepheid variable–calibrated supernovae being the most outlying, followed by the time-delay strong-lensing result. Considering the possibility that some nonstandard physics may reconcile the constraints, we provide a general discussion of nonstandard models with modifications at high, mid, or low redshifts and the effect of local environmental factors. Due to the different responses of individual constraints to a modified model, it is not easy for nonstandard models to reconcile all constraints if none of them have unaccounted-for systematic effects.
Natural reward drives the advancement of life
Authors: Gilbert Owen M.
Published: November 2020

Throughout the history of life on earth, rare and complex innovations have periodically increased the efficiency with which abiotic free energy and biotic resources are converted to biomass and organismal diversity. Such macroevolutionary expansions have increased the total amount of abiotic free energy utilized by life and shaped the earth’s ecosystems. Meanwhile, Darwin’s theory of natural selection assumes a historical, worldwide state of effective resource limitation, which could not possibly be true if life evolved from one or a few original ancestors. In this paper, I analyze the self-contradiction in Darwin’s theory that comes from viewing the world and universe as effectively resource limited. I then extend evolutionary theory to include a second deterministic evolutionary force,natural reward. Natural reward operates on complex inventions produced by natural selection and is analogous to the reward for innovation in human economic systems. I hypothesize that natural reward, when combined with climate change and extinction, leads to the increased innovativeness, or what I call theadvancement, of life with time. I then discuss applications of the theory of natural reward to the evolution of evolvability, the apparent sudden appearance of new forms in the fossil record, and human economic evolution. I conclude that the theory of natural reward holds promise as an explanation for the historical advancement of life on earth.
Enraciner les jeunes d’Algérie
Authors: Lang Alexander , Simon Claire
Published: November 2020

Cet article retrace l’adaptation des Chantiers de la jeunesse du régime de Vichy au contexte algérien. Confrontés à une série de tensions sociales, les responsables de Vichy espéraient resserrer le contrôle sur les jeunes Algériens musulmans grâce à la mise en place des Chantiers. En croissant les sources, l’article vise à restituer à la fois les priorités des concepteurs des camps et les expériences des jeunes pour décrire ce projet central aux réformes de Vichy dans les trois départements algériens, reposant sur l’inculcation d’un Islam dépolitisé censé assurer la loyauté des jeunes algériens éduqués tout en enseignant des techniques agricoles aux jeunes paysans afin de ralentir l’exode rural. Si l’expérience tourna court, interrompue par l’invasion des Alliés fin 1942, l’examen des Chantiers en Algérie révèle la spécificité des approches conservatrices du projet colonial.
Surveiller les mobilisations, se mobiliser sous surveillance
Authors: Bollenot Vincent
Published: November 2020

Dans Colonial Suspects (2018), Kathleen Keller étudie la mise en place d’un appareil de surveillance en Afrique-Occidentale française (AOF) entre les années 1910 et les années 1930. Mais à trop considérer que ceci relève de la paranoïa des colonisateurs, elle néglige l’étude des mobilisations anti-impérialistes globales, dont l’histoire est en plein renouveau. Inversement, ce domaine, représenté par les livres dirigés en 2013 et 2016 par Holger Weiss, néglige la critique des sources issues du renseignement politique colonial. À partir de ces exemples, l’article plaide pour une articulation de l’histoire de l’action publique et des mobilisations collectives.
Elzéar, le recrutement au service de la croissance des champions cachés
Authors: de Prémare Thibaud , Jullié Franck
Published: November 2020

Créé en 2006, Elzéar est un cabinet de recrutement par approche directe, spécialisé dans les champions cachés, ces PME ou ETI industrielles très performantes, mais peu connues du grand public. Les jeunes ingénieurs, commerciaux ou financiers ne pensent généralement pas à adresser leurs CV à ces entreprises, car il s’agit souvent de groupes provinciaux, B to B , spécialistes de niches. Elzéar déploie des “ruses de Sioux” pour détecter des talents rares et les convaincre d’aller travailler dans l’entreprise qui a besoin d’eux.

Évaluation multidimensionnelle bi-phasique et reconnaissance des besoins spécifiques des enfants migrants
Authors: Goguikian Ratcliff Betty , Kameri Liridona
Published: November 2020

L’article traite des effets de la mondialisation sur le développement de l’enfant migrant, en particulier ceux au statut légal précaire, réfugiés et sans papiers. Il décrit une triade d’expériences délétères, exposition à des événements potentiellement traumatiques, séparations familiales précoces et carences éducatives, caractéristique du vécu de ces enfants. Il montre comment de telles expériences, et leur cumul, portent atteinte aux besoins fondamentaux de l’enfant et surchargent ses capacités d’adaptation et de réinsertion scolaire post-migratoire. A travers un cas clinique, il illustre une méthode d’évaluation multidimensionnelle bi-phasique permettant de mieux comprendre la nature des difficultés présentées par un enfant migrant, en vue de proposer des interventions plus ciblées et efficaces.
Une ONG en analyse
Authors: Gratton Emmanuel , Bansard Nolhan
Published: November 2020

Une organisation non gouvernementale africaine menant des actions en direction des enfants des rues accueille régulièrement des stagiaires occidentaux, notamment en psychologie, qui participent à son activité aux côtés d’éducateurs salariés locaux. Cela pose la question de l’acculturation et des relations interculturelles à l’œuvre. Une demande d’analyse de la pratique a été réalisée par la direction de cette ONG. Une analyse psychosociologique et clinique de l’ONG a été réalisée à partir des observations des stagiaires et ex-stagiaires et des discours des participants à cette analyse de la pratique. Le modèle théorique principal choisi est celui de l’emboitement des sept instances qu’Eugène Enriquez présente dans L’organisation en analyse (2003). Par ailleurs, la prise en compte de la dimension interculturelle entre un pays anciennement colonisé et un pays anciennement colonisateur permet de mettre en exergue certains dysfonctionnements organisationnels et des dynamiques intergroupes.
Edible arachnids and myriapods worldwide – updated list, nutritional profile and food hygiene implications
Authors: Costa-Neto E.M. , Grabowski N.T.
Published: November 2020

Like insects, arachnids (spiders, scorpions, mites and ticks) and myriapods (millipedes and centipedes) also have a history of traditional consumption, either as foodstuff or medicine. In this review, an updated list of edible arachnids and myriapods is presented, showing that these animals are consumed worldwide. They are collected from the wild, and typical processing includes heating, defanging and, in certain cases, drying and grinding. The scarce data show a marked variation in nutrient composition that depends on the taxon and even sex, possibly also instar and feeding. Evaluating these traditions in terms of food safety, tick consumption must be discouraged, and heating steps are mandatory to eliminate pathogens, venoms, and urticating setae. For the future, more research will be necessary to assess chemical risks in wild-caught animals in terms of consumer safety and to get productive arachnid and myriapod farming for foodstuffs and industrial uses (pharmaceutical substances and silks) started.

On a linearized Mullins-Sekerka/Stokes system for two-phase flows
Authors: Abels Helmut , Marquardt Andreas
Published: November 2020

We study a linearized Mullins-Sekerka/Stokes system in a bounded domain with various boundary conditions. This system plays an important role to prove the convergence of a Stokes/Cahn-Hilliard system to its sharp interface limit, which is a Stokes/Mullins-Sekerka system, and to prove solvability of the latter system locally in time. We prove solvability of the linearized system in suitable \begin{document}$ L^2 $\end{document}-Sobolev spaces with the aid of a maximal regularity result for non-autonomous abstract linear evolution equations.
Stochastic delay differential equations of three-species prey-predator system with cooperation among prey species
Authors: Rihan Fathalla A. , Alsakaji Hebatallah J.
Published: November 2020

Environmental factors and random variation have strong effects on the dynamics of biological and ecological systems. In this paper, we propose a stochastic delay differential model of two-prey, one-predator system with cooperation among prey species against predator. The model has a global positive solution. Sufficient conditions of existence and uniqueness of an ergodic stationary distribution of the positive solution are provided, by constructing suitable Lyapunov functionals. Sufficient conditions for possible extinction of the predator populations are also obtained. The conditions are expressed in terms of a threshold parameter \begin{document}$ {\mathcal R}_0^s $\end{document} that relies on the environmental noise. Illustrative examples and numerical simulations, using Milstein's scheme, are carried out to illustrate the theoretical results. A small scale of noise can promote survival of the species. While relative large noises can lead to possible extinction of the species in such an environment.
On projective threefolds of general type with small positive geometric genus
Authors: Chen Meng , Hu Yong , Penegini Matteo
Published: November 2020

In this paper we study the pluricanonical maps of minimal projective 3-folds of general type with geometric genus $ 1 $, $ 2 $ and $ 3 $. We go in the direction pioneered by Enriques and Bombieri, and other authors, pinning down, for low projective genus, a finite list of exceptions to the birationality of some pluricanonical map. In particular, apart from a finite list of weighted baskets, we prove the birationality of $ \varphi_{16} $, $ \varphi_{6} $ and $ \varphi_{5} $ respectively.
Traveling wave solution for a diffusion SEIR epidemic model with self-protection and treatment
Authors: Huo Hai-Feng , Hu Shi-Ke , Xiang Hong
Published: November 2020

A reaction-diffusion SEIR model, including the self-protection for susceptible individuals, treatments for infectious individuals and constant recruitment, is introduced. The existence of traveling wave solution, which is determined by the basic reproduction number $ R_0 $ and wave speed $ c, $ is firstly proved as $ R_0>1 $ and $ c\geq c^* $ via the Schauder fixed point theorem, where $ c^* $ is minimal wave speed. Asymptotic behavior of traveling wave solution at infinity is also proved by applying the Lyapunov functional. Furthermore, when $ R_0\leq1 $ or $ R_0>1 $ with $ c\in(0,\ c^*), $ we derive the non-existence of traveling wave solution with utilizing two-sides Laplace transform. We take advantage of numerical simulations to indicate the existence of traveling wave, and show that self-protection and treatment can reduce the spread speed at last.
Stochastic maximum principle for problems with delay with dependence on the past through general measures
Authors: Guatteri Giuseppina , Masiero Federica
Published: November 2020

We prove a stochastic maximum principle for a control problem where the state equation is delayed both in the state and in the control, and both the running and the final cost functionals may depend on the past trajectories. The adjoint equation turns out to be a new form of linear anticipated backward stochastic differential equations (ABSDEs in the following), and we prove a direct formula to solve these equations.
New species of Eirenidae (Hydrozoa: Leptothecata) from the Amazonian coast (northern Brazil)

Two new Eirenidae medusae species were collected on the Amazonian coast, Eutima marajoara n. sp. and Helgicirrha angelicae n. sp. The former differs from other species of the genus by the gonads extending along almost the entire length of the subumbrellar portion of the radial canals but not connected to the ring canal, up to 40 marginal tentacles with conical bulbs and 48 marginal warts, lateral cirri and adaxial papillae on some marginal warts and tentacular bulbs. Helgicirrha angelicae n. sp. differs from other species of the genus by the gonads on the middle portion of the radial canals with medusa buds, the short gastric peduncle, up to 20 marginal tentacles, some with adaxial papillae, up to three marginal warts and two statocysts between successive tentacles, and lateral cirri both on tentacle bulbs and marginal warts.
The benthos: the ocean’s last boundary?
Authors: Gili Josep-Maria , Vendrell-Simón Begoña , Arntz Wolf , Sabater Francesc , Ros Joandomènec
Published: November 2020

Benthic communities depend on receiving much of their food from the water column. While sinking, particles are transformed in a discontinuous process and are temporally retained in transitional physical structures, which act as boundaries and contribute to their further transformation. Motile organisms are well-acquainted with boundaries. The number, width and placement of boundaries are related to the degree of particle degradation or transformation. Progressively deepening within each boundary, particles are degraded according to their residence time in the discontinuity and the activity of the organisms temporarily inhabiting that boundary. Finally, particles reach the seafloor and represent the main food source for benthic organisms; the quality and quantity of this food have a strong impact on the development of benthic communities. However, benthic communities not only play the role of a sink of matter: they act as an active boundary comparable to other oceanic boundaries, in accordance with the boundary concept proposed by the ecologist Ramon Margalef.
The publications of Ramon Margalef in Investigación Pesquera and Scientia Marina: The beginnings of marine ecology in the CSIC
Authors: Estrada Marta , Alcaraz Miquel
Published: November 2020

Ramon Margalef López (1919-2004) was one of the most prominent scientists of the 20th century in the fields of limnology, oceanography and ecology. His contributions to theoretical ecology, which won him international recognition, were based on a great deal of laboratory and field work and on extensive observations of the natural world, a passion that he acquired at a young age. Some of the early papers of Ramon Margalef appeared in the Publicaciones del Instituto de Biología Aplicada, but as of 1955 many of his marine studies were published in Investigación Pesquera, the journal of the Instituto de Investigaciones Pesqueras of the CSIC in Barcelona. He also wrote several articles for Scientia Marina, the journal that replaced Investigación Pesquera in 1989 after the Instituto de Investigaciones Pesqueras became the Institut de Ciències del Mar. The present article aims to give an overview of Margalef’s contributions to these journals to mark the celebration in 2019 of the 100th anniversary of his birth.
The Concept of Justice in Stakeholder Theory: A Systematic Literature Review
Authors: Pessôa de Melo Victor , Taumaturgo Ítalo , De Oliveira Santos Jhunior Ronaldo , Torres Uchôa Mariana
Published: November 2020

In strategic management, the Stakeholder Theory proclaims that in order to achieve better performance and sustainable competitive advantage, the organization has to treat each of its stakeholders fairly. Hence, the concept of justice becomes relevant in assessing the effectiveness of managerial decisions and is ingrained in the Stakeholder Theory literature. This paper aims to examine how the notion of justice is conceptualized and applied in the Stakeholder Theory literature; and to propose new avenues of research regarding the interconnections between these two subjects. We present a systematic literature review to synthesize the research in the area. A careful screening held in April 2019, resulted in 75 papers published in 35 journals from 1999 to 2019. The results were presented in two phases. First, in the form of a descriptive and bibliometric analysis of the selected papers. Second, by reviewing those papers, we offer a framework of how the notion of justice has been conceptualized and applied in the Stakeholder Theory literature. Finally, we propose an agenda for future research regarding the interconnection between justice and Stakeholder Theory.
Determinantes de Inadimplência e de Recuperação de Crédito em um Banco de Desenvolvimento
Authors: Amaral Gustavo Henrique de Oliveira , Iquiapaza Robert Aldo
Published: November 2020

Considering the latest financial crises and because of the increasingly importance of credit risk management to economic actors and academics, this research aims to identify the conditioning factors of non-performing loans and credit recovery of a development bank portfolio. We analyzed data of 20.241 loans granted to micro and small enterprises between November 2009 and November 2014. To achieve the research goals, non-performing loan and loan recovery models were estimated by logistic regression. The results point out the significant effects on determining non-performing loans and/or credit recovery of (i) individual characteristics, such as firm’s age, (ii) loan characteristics, like the financial product and the installment payment period, and (iii) lending relationship, such as the number of years of relationship with the development bank. Contrary to the arguments of part of the literature, the results do not suggest any reverse relation between non-performing loans and credit recovery explanatory variables, which could enhance the loss from credit risk misspecification.

Human Immunodeficiency Virus (HIV) infection still represents an important public health problem, because it involves clinical, epidemiological, social, economic and political issues. We analyzed the temporal and spatial pattern of the HIV incidence in an area of social inequality in northeast Brazil and its association with socioeconomic indicators. An ecological study was carried out with a focus on all HIV cases reported in Alagoas State, Northeast Brazil from 2007 to 2016 using its 102 municipalities as the units of our analysis. Data from the Brazilian information systems were used. Georeferenced data were analyzed using TerraView 4.2.2 software, QGis 2.18.2 and GeoDa 1.14.0. Time trend analyses were performed by the Joinpoint Regression software and the spatial analyses included the empirical Bayesian model and Moran autocorrelation. Spatial regression was used to determine the influence of space on HIV incidence rate and socioeconomic inequalities. There was an increasing trend of HIV rates, especially in the municipalities of the interior. Significant spatial correlations were observed with the formation of clusters with emphasis on the coast of the state and in tourist regions. Spatial regression explained 46% of the dependent variable. The HIV incidence rate was positively influenced by rate of primary health care units (P=0.00), and negatively by Gini index (P=0.00) and proportion of heads of household without or low education (P=0.02). We conclude that the relationship found between indicators of better socioeconomic conditions and HIV infection suggests unequal access to the diagnosis of infection. Prevention and control strategies can be established according to each epidemiological reality.

An increasing amount of waste concurrently further extends the risk of exposure to hazardous material among waste collectors. In light of the COVID-19 crisis, municipal waste collectors are one of the most at-risk groups of SARS-Cov-2 exposure. Risk assessment included hazard identification, evaluation of existing control level at the workplace, estimation of likelihood and severity of hazard, risk determination, and control measure recommendations. Five waste collection activities were identified and reviewed. High-risk exposure includes collection of garbage, mechanical manipulation of compactor lorries and unloading of garbage at the disposal site. There is poor practice of personal hygiene and unestablished continuous monitoring of personal protective equipment supplies. The preventive measures in the waste collection industry are influenced by several factors. Until the preventive measures are adopted into practice and adapted according to each company's requirements, biological agents continue to be risk factor to the health workers.
The End of Ideology
Authors: Willems Brian
Published: November 2020

The poetry in Cathy Park Hong's Empire Engine (2012) is separated into three timelines: the period of Westward Expansion in the United States, a contemporary story of fine art reproduction in China, and a futurist story of data workers in California. These three sections are united in their interrogation of the role of ideology in creating and sustaining an empire. I argue that the first timeline stages a representation of ideology in the traditional Althusserian sense, that the second timeline shows this representation as inadequate, and most importantly, that the final section suggests a new model for oppression. The key for the new model presented in the third timeline lies in the job the workers have: they work with data. The main argument is that the ruling class no longer maintains its power through the ownership of capital. Instead, as McKenzie Wark maintains in Capital is Dead (2019), this ruling class »owns and controls information« (Wark 5). The owning and controlling of information is no longer capitalism, »but something worse« (29). Following on Wark, I argue that this use and abuse of data changes ideology in a fundamental manner. Rather than having a world from which an individual can feel more or less estranged in an Althusserian sense, the new reign of data suggests that estrangement is the fundamental experience of the world. In other words, there is no world to feel estranged from, thus leading to ideology; rather, the feeling of estrangement is already the fundamental experience of our data-driven reality. While in Hong's book this new model is located in the future, the end of the essay argues that a similar state is brought about not only by our data-driven world, but also pandemics such as that caused by COVID-19, which are part of our time now.
Pain control with ibandronate for bone marrow oedema of the knee
Authors: Küchler Livia , Fehr Thomas , Jeker Raphael

INTRODUCTION
Bone marrow oedema is a disabling disease characterised by severe bone pain (with or without prior trauma), insufficient response to analgesics, and reduction of weight bearing. Several studies showed promising results after using bisphosphonates to inhibit osteoclast activity. The aim of this study was to investigate the association between ibandronate administration and pain relief in patients with bone marrow oedema of the knee, and to precisely describe its presentation in magnetic resonance imaging (MRI).

METHODS
This is a single-centre, retrospective analysis of 18 patients who received intravenous ibandronate due to bone marrow oedema of the knee between April 2012 and February 2016. Information has been extracted from our clinical database and a questionnaire. Furthermore, an experienced radiologist reassessed all MRI diagnoses.

RESULTS
Our results showed a significant reduction of pain from 7.4 to 3.8 points on the visual analogue scale (p = 0.0001; median follow-up 41.5 months). Furthermore, the disability in daily life also significantly decreased (p = 0.008); 55.6% of the participants stated to be pain-free in the follow-up, and the same percentage also did not use alternative therapies after completing therapy with ibandronate (e.g., regular use of analgesics, operation, or local infiltration). However, there was no significant correlation between pain and specific radiologic findings.

CONCLUSIONS
Participants with bone marrow oedema of the knee showed a significant pain reduction after an administration of ibandronate, independently of the severity showed in MRI. If the first administration leads to an insufficient control of pain, the administration of a second dose may be helpful. As bone marrow oedema syndrome is a self-limiting disease, prospective studies with a comparison group are needed to distinguish between the natural course of the disease and the beneficial effects of bisphosphonates.
Narcyzm – autentyczność – atopia. Cyfrowe twarze „nowego człowieka”
Authors: Burszta Wojciech Józef , Rydlewski Michał
Published: November 2020

Narcissism –authenticity –atopy. Digital faces of the “New Man” Narcissism, as mentioned by many authors, is one of the defining characteristics of modern culture. Substantial technological changes, especially in communication and media changed our own experience of aloof narrative of ourselves into a narrative “from ourselves”, by means of democratization and fetishization of the self-narrative. It would not be possible to such extent if not for the unprecedented expansion of multimedia and the complete time consumption which they offer. It can be said that the digital culture and its typical logorrhea of word-pictures are the very core of XXI century narcissism in all its appearances and allow us to think that a completely new man is created who finally can exercise his/her own individuality without boundaries and can be “authentic”. One of the most insightful observers of that oecumenical illusion is Byung-Chul Han – a German culture expert and philosopher whose reflections we fill with empirical matter.
For Now We See through an AI Darkly; but Then Face-to-Face: A Brief Survey of Emotion Recognition in Biometric Art
Authors: Schiller Devon
Published: November 2020

Our knowledge about the facial expression of emotion may well be entering an age of scientific revolution. Conceptual models for facial behavior and emotion phenomena appear to be undergoing a paradigm shift brought on at least in part by advances made in facial recognition technology and automated facial expression analysis. And the use of technological labor by corporate, government, and institutional agents for extracting data capital from both the static morphology of the face and dynamic movement of the emotions is accelerating. Through a brief survey, the author seeks to introduce what he terms biometric art, a form of new media art on the cutting-edge between this advanced science and technology about the human face. In the last ten years, an increasing number of media artists in countries across the globe have been creating such biometric artworks. And today, awards, exhibitions, and festivals are starting to be dedicated to this new art form. The author explores the making of this biometric art as a critical practice in which artists investigate the roles played by science and technology in society, experimenting, for example, with Basic Emotions Theory, emotion artificial intelligence, and the Facial Action Coding System. Taking a comprehensive view of art, science, and technology, the author surveys the history of design for biometric art that uses facial recognition and emotion recognition, the individuals who create such art and the institutions that support it, as well as how this biometric art is made and what it is about. By so doing, the author contributes to the history, practice, and theory for the facial expression of emotion, sketching an interdisciplinary area of inquiry for further and future research, with relevance to academicians and creatives alike who question how we think about what we feel.
Christianity as the Basis of Wincenty Lutosławski’s “Polish Yoga”
Authors: Świerzowska Agata
Published: November 2020

The article is an attempt to show the importance of Christianity in the reinterpretation of the Indian yoga tradition, in order to include it in a new (Polish) cultural context. Christianity allowed transformation of this culturally alien concept in such a way that it ceased to be seen as something foreign and exotic, and started to be treated as a Polish discipline –in a way specifically addressing the needs and conditions of the Polish nation. The article focusses on the approach to yoga proposed by Wincenty Lutosławski, the author of the first “Polish yoga”handbook, although other interpretations are also referred to, in order to demonstrate the widest possible approach to this discipline.
Activities of the Theosophical Society and the Order of the Star in the East in the Czech Lands until 1939
Authors: Szymeczek Józef
Published: November 2020

The study shows the penetration of the Theosophical movement into Austro-Hungarian territory, highlighting this process in the Czech lands from the end of the 19th century. It also examines the development of the Theosophical movement in the territory of Czechoslovakia during the interwar period, and analyses the conflict that occurred in the Theosophical circles as the result of accepting or rejecting the teachings of Jiddu Krishnamurti, recognised as the manifestation of Majtreja, but also as the expected Messiah. The analysis also considers the activities of the Star Order in the East, which was founded for the purpose of spreading the teachings of Krishnamurti.
