Voiceless Screams: Pictorialism as Narrative Strategy in Horror Silent Cinema
Authors: Enyedi Delia 
Published: April 2021

Abstract
As a complementary condition to narrative, the notion of pictorialism in film is rooted in the first decades of the medium. In their quest to demonstrate the capturing and restoring of images with various devices, early filmmakers selected views with pictorial qualities in the long-standing tradition of painting, transferring them on film in the form of non-narrative shots. The evolution of fictional narratives in silent cinema displaced the source of inspiration in theatre, assimilating its nineteenth-century tradition of pictorialism. Thus, the film audiences’ appeal for visual pleasure was elevated with balanced elements of composition, framing and acting that resulted in pictorially represented moments actively engaged in the narrative system. The paper explores the notion of “pictorial spirit” (Valkola 2016) in relation to that of “monstration” (Gaudreault 2009) aiming to describe the narrative mechanism of provoking fear by means of pictorially constructed cinematic images in a selection of short-length horror silent films belonging to the transitional era, consisting in The Haunted House/The Witch House (La Maison ensorcelée/La casa encantada, Segundo de Chomón, 1908), Frankenstein (J. Searle Dawley, 1910) and the surviving fragments of The Portrait (Портрет, Vladislav Starevich, 1915).1
The Tableau Vivant and Social Media Culture
Authors: Männig Maria 
Published: April 2021

Abstract
The article aims to analyse the tableau vivant in social media culture by emphasizing its intermedial relation to technical visual media, particularly digital photography and film. By focusing on the living picture’s specific mimetic qualities, the study traces back the tableau vivant’s history in a media archaeological perspective primarily regarding photography. It explores the current revival of the tableau vivant within social media. The article examines living pictures and the aspect of self-staging, relevant to contemporary digital culture. The tableau vivant develops between two polarities: a primarily analytical approach that allows a profound exploration of a particular artwork and the performative aspects of self-staging.

Authors: Baishya Kanak Kanti , Chowdhury Partha Roy 
Published: April 2021

Abstract
The object of the present paper is to study generalized weakly symmetric and generalized weakly Ricci symmetric Kenmotsu manifolds whose metric tensor is η-Ricci soliton. The paper also aims to bring out curvature conditions for which η-Ricci solitons in Kenmotsu manifolds are sometimes shrinking or expanding and some other time remain steady. The existence of each generalized weakly symmetric and generalized weakly Ricci symmetric Kenmotsu manifold is ensured by an example.
Body fatness in sedentary and active students with different body mass index

Published: April 2021

AbstractStudy aim: Numerous data have indicated that body fat stores undergo complicated regulation by genetic and environmental factors, including physical activity. However, the majority of studies did not take into account this aspect of lifestyle in proposed body fat limits. In this context it seems that a more precise and reliable classification of body fat is provided by the American Council on Exercise (ACE), which distinguishes individuals not only with respect to sex but also activity level.Material and methods: A total of 793 students (312 sedentary and 481 active) volunteered to participate in the study. Among sedentary participants 147 were male and 165 female. Among active subjects 206 were male and 275 were female. Active subjects were engaged in different modes of physical activity according to the study program. In all participants body mass index (BMI) was calculated. In participants with BMI 18.5–24.9 and BMI ≥ 25 body fat was determined using four skinfold measurements. Thereafter participants were classified according to the percentage of body fat using ranges for males and females provided by the American Council on Exercise (ACE) (essential fat, athletes, fitness, average and obese fatness).Results: None of the sedentary and active males with BMI 18.5–24.9 had high (obese) fat. In contrast, in sedentary males with BMI ≥ 25 16.4% were obese vs. 1.8% of obese active ones. In sedentary females BMI from 18.5 to 24.9 did not exclude obesity, which was found in 16.9% of participants. In sedentary females with BMI ≥ 25 most of the subjects (97.1%) were obese. In contrast, in active females with BMI ≥ 25 a similar percentage of participants had average and obese fat (53.3% and 46.7, respectively).Discussion: Our study clearly demonstrated that BMI as a simple measure of body composition provides false information concerning true adiposity in physically active male and female students. A similar BMI did not exclude marked differences in the percentage of body fat in sedentary and active students.
Effect of environmental gradients on diversity and plant community distribution in remnant dry Afromontane forest of Mount Duro, Nagelle Arsi, Ethiopia
Authors: Teshome Mengistu , Asfaw Zebene , Dalle Gemedo 
Published: April 2021

Abstract
For forest ecosystem management to be effective, explicit understanding of the species diversity-environmental relationship along elevation gradient is crucial. This study aimed at identifying and describing plant communities and also documenting their species diversity. Evaluation of relationships between selected environmental variables and species diversity was another objective of this study. Systematic sampling techniques were used to collect vegetation data in a total of forty two sample plots (size=20×20 m). Within main plots, four sub-plots of 5×5 m were established at four corners and – one sub-plot of the same size in the center. These plots were used for shrub and herb diversity assessment. Within each sample plot, all plant species were documented and their scientific names were identified. Environmental variables, such as: elevation, aspect and slope, were also recorded for each main plot. Species diversity was determined using Shannon-Wiener diversity index and evenness in R statistical software. Agglomerative hierarchical clustering method was used for plant community classification. The total of 44 plant species belonging to 30 families was documented. Four plant community types were identified with different diversity, evenness and species richness. These plant communities were: Afrocurpus falcatus-Ficus sur, Maesa lanceolata-Bersama abyssinica, Vernonia myriantha-Urera hypselodendron and Croton machrostachus-Tecleanobilis occurring at average elevation of 2521, 2429, 2329, and 2364 m asl, respectively. Maesa lanceolata-Bersama abyssinica community type exhibited the highest species diversity and evenness followed by Croton machrostachus-Teclea nobilis community type showing the fact that median elevation ranges were rich in species. Elevation and slope gradient explained significant variation in species richness in the studied forest. For effective conservation of biodiversity and sustainable management of the forest ecosystem, further research on the impacts of anthropogenic disturbances and soil properties is recommended as a result of this study.
A Vessel of the Funnel Beaker Culture at Salgótarján-Pécs-Kő
Authors: Horváth Tünde , Kreiter Attila , Viktorik Orsolya 
Published: April 2021

Abstract
This study describes and discusses an old find from a wholly new perspective. The non-local fragment or fragments represent imports or imitations that can be linked to the Funnel Beaker culture and not to Kostolác, Coţofeni, Livezile or Bošáca as originally suggested by József Korek. The hallmarks distinctive to the culture are the ornamented rim exterior and rim interior, the zigzag motif under the rim and the ladder motif on the belly. However, the channelling on the belly is a typical Baden trait, which has not been noted on Funnel Beaker vessels to date. The best and closest analogies can be cited from the Baden settlement at Oldalfala/Stránska–Mogyorós, where they were erroneously identified as Coţofeni/Livezile imports. The occurrence of Funnel Beaker pottery on several sites on the southern fringes of the Western Carpathians suggests a more complex situation; however, their stratigraphic contexts on these multi-period, stratified sites remain unclear due to the field techniques employed during the old excavations. The determination of the exact place of origin is rather difficult within the culture’s vast distribution, although they can most likely be assigned to the Funnel Beaker eastern group, Wiórek phase (IIIB – IIIB-C in the current terminology), whose absolute dates fall between 3700/3600 and 3200 BC. The petrographic analyses revealed that the clay and the tempering agents are of local volcanic origin, providing conclusive evidence that Funnel Beaker vessels had been made locally. In this sense, the pottery fragment discussed here can be best described as a local hybrid product.
Pottery of Pikutkowo Type in the Funnel Beaker Culture: Characteristics, Dispersion and Context
Authors: Kośko Aleksander , Szmyt Marzena 
Published: April 2021

Abstract
The article discusses the current state of knowledge concerning the set of specific pottery characteristics of the Funnel Beaker culture that constitutes the so-called Pikutkowo stylistics. It is especially strongly represented in Kujawy, where the changes in the Pikutkowo set of characteristics define Phases IIIB and IIIB-C dated to 3700-3200 BC. Already in 3700/3650-3500 BC, Pikutkowo pottery appears not only on the Polish Lowland (including Wielkopolska and central Poland as well as the Chełmno Land and Gostynin Lake District), but also on the old Uplands in the upper Vistula basin. The latest data indicate that at the same time Pikutkowo characteristics are also present in Funnel Beaker assemblages from the Subcarpathian foothills and upper Dniester area. It is argued that this wide distribution delimits the Pikutkowo stylistics space, which was a zone of active circulation of cultural patterns within the Funnel Beaker culture. The culture-forming potential of this zone is best seen in the increased transfer of one of the key technological innovations of the Eneolithic, i.e. copper (including arsenic copper) use and processing.
The Deepest Strand. Isiah Berlin and the Intellectual History of Russia
Authors: Ackroyd John 
Published: April 2021

Abstract
Isaiah Berlin’s essays on the nineteenth-century Russian intelligentsia throw light not only on their subject – the role of that group in preparing the ideational ground for the coming revolutions – but more broadly on Berlin’s central philosophical preoccupations and historiographical and hermeneutical assumptions and method. I try to show this – the centrality to his overall project of Berlin’s work on the Russians – by contextualising that work within the broader framework of his philosophical and historical thought.
The influence of civil society on Ukrainian anti-corruption policy after the Maidan
Authors: Blatt Felix , Schlaufer Caroline 
Published: April 2021

Abstract
This article examines the influence of civil society on Ukrainian anti-corruption policy after the Maidan in 2014. Drawing on the Advocacy Coalition Framework (ACF), we hypothesise that the Maidan events led to a redistribution of formal legal authority in the anti-corruption policy subsystem, opened access to policy venues for civil society actors, and increased leverage of international organisations to push for strict reforms. We test these expectations with a systematic content analysis of primary documents and semi-structured interviews. Findings show that changes in the formal legal authority to make policy decisions led to anti-corruption policy change. The newly adopted policies were largely influenced by civil society actors who had increased venue access after the Maidan. In addition, civil society advocated for strict anti-corruption reforms through international organisation.
Using Pathological Elements in Analog Circuit Analysis and Simulation
Authors: Grib Alexandru , Erdei Zoltan , Turcu Mihaela Cristina , Constantin Alina , Iordache Mihai 
Published: April 2021

AbstractThis paper is focused on some kind of mystery circuit nullator, nullor, current mirror, and voltage mirror, all of them known as pathological elements. These pathological elements can be used to perform circuit modelling, symbolic circuit analysis, circuit synthesis, circuit design and to develop applications that involve modern active devices. It is described a new modeling of nullor-based active devices from the circuit abstraction level. In this paper it is presented the way all types of equations which describe the circuit containing nullors can be directly formulated from the diagrams of these circuits if we took into account that a nullator is an over-determined two-port circuit element (zero voltage, zero current) and the norator is an undetermined two-port circuit element (any voltage and any current). To simulate the nullors with ideal voltage controlled voltage sources, ec = Ac_c uc, with the control gate an ideal independent current source, jC = 0.0 A and with the amplification (transfer) factor Ac_C very big (theoretically ∞), the analog circuits with nullors can be analyzed by using any of the existing simulation software. By this way, it was possible the elaboration of efficient algorithms for an automatic formulation of Kirchhoff’s equations, of loop equations, of modified nodal equations and of state equations for circuits with pathological elements. These procedures can be easily implemented in dedicated programs for the simulations of the complex analog circuits with pathological elements. The example presented in this paper validates the presented models for nullors.
Species distribution model for Buxbaumia viridis, identifying new areas of presumed distribution in the Czech Republic.
Authors: Číhal Lukáš , Fialová Lucie , Plášek Vítězslav 
Published: April 2021

Abstract
There is a large number of organisms in nature that are hard to find in the field, and one of these is also a rare bryophyte species, Buxbaumia viridis, which can also only be found in a certain part of the year in the production of sporophytes. Using distribution models, however, it is possible to predict the locations which this species is likely to be present at and to focus the field research directly on such sites. Thanks to the presented model, we have succeeded in identifying areas within the Czech Republic with an increased likelihood of its occurrence, even in some areas where no collection of B. viridis has so far been recorded. With the help of the maps created these locations can be identified with the accuracy of approximately 1 km2, making it easier for terrain research and resulting time and often financial expenses. We have also focused on the study of ecological factors that influence the occurrence of the species, and by testing variables from different categories we have come to some agreement with previously published studies. Whilst we have managed to exclude that air pollution has a major role to its occurrence, which has not yet been the subject of any study.

Forecasting the Yield Curve for Poland
Authors: Kostyra Tomasz Piotr , Rubaszek Michał 
Published: April 2021

Abstract
This paper evaluates the accuracy of forecasts for Polish interest rates of various maturities. We apply the traditional autoregressive Diebold-Li framework as well as its extension, in which the dynamics of latent factors are explained with machine learning techniques. Our findings are fourfold. Firstly, they show that all methods have failed to predict the declining trend of interest rates. Secondly, they suggest that the dynamic affine models have not been able to systematically outperform standard univariate time series models. Thirdly, they indicate that the relative performance of the analyzed models has depended on yield maturity and forecast horizon. Finally, they demonstrate that, in comparison to the traditional time series models, machine learning techniques have not systematically improved the accuracy of forecasts.
From the Ottoman Empire to pre-Islamic Central Asia: Theatre as an Ideological Tool
Authors: Baş Elif 
Published: April 2021

Abstract
After Mustafa Kemal Atatürk founded the new Turkish Republic in 1923, the country went through a swift and radical transformation. The ruling elite made use of all possible tools to impose the ideals of the new Republic. Their main objective was to break the bonds with the Islamic Ottoman past to establish a new secular national identity. The essence of the new Turkish nation was found in pre-Islamic Central Asia. This view was supported with the help of the Turkish History Thesis, which asserted that the Turks are a supreme race, and their origins are from Central Asia. The state tried to propagate this thesis by various means. The most effective tool that could reach the illiterate people during that period was the theatre. Accordingly, the aim of this article is to explore how the state disseminated the Turkish History Thesis and the values of the new Republic through theatre. The emergence of this new narrative coincided with the tenth anniversary of the Turkish Republic. The plays, written in 1933, especially for this occasion, will be analyzed to determine how they support the Turkish History Thesis and the values of the new nation. Two plays, Akın (The Raid) and its sequel Özyurt (Homeland), will be explored in detail to give an elaborate account of the ideology behind such plays written during that period.
The Adhesive Response of Regolith to Low-Energy Disturbances in Microgravity
Authors: Jarmak Stephanie , Colwell Joshua , Dove Adrienne , Brisset Julie 
Published: April 2021

Abstract
Small, airless bodies are covered by a layer of regolith composed of particles ranging from μm-size dust to cm-size pebbles that evolve under conditions very different than those on Earth. Flight-based microgravity experiments investigating low-velocity collisions of cm-size projectiles into regolith have revealed that certain impact events result in a mass transfer from the target regolith onto the surface of the projectile. The key parameters that produce these events need to be characterized to understand the mechanical behavior of granular media, which is composed of the surfaces of small bodies. We carried out flight and ground-based research campaigns designed to investigate these mass transfer events. The goals of our experimental campaigns were (1) to identify projectile energy thresholds that influence mass transfer outcomes in low-energy collision events between cm-size projectiles and μm-size regolith, (2) to determine whether these mass transfer events required a microgravity environment to be observed, and (3) to determine whether the rebound portion of these collision events could be replicated in a laboratory drop tower environment. We found that (1) mass transfer events occurred for projectile rebound accelerations <7.8 m/s2 and we were unable to identify a corresponding impact velocity threshold, (2) mass transfer events require a microgravity environment, and (3) ourdrop tower experiments were able to produce mass transfer events. However, drop tower experiments do not exactly reproduce the free-particle impacts and rebound of the long-duration microgravity experiments and yielded systematically lower amounts of the overall mass transferred.
Shared Metabolic Remodeling Processes Characterize the Transcriptome of Arabidopsis thaliana within Various Suborbital Flight Environments
Authors: Califar Brandon , Zupanska Agata , Callaham Jordan A. , Bamsey Matthew T. , Graham Thomas , Paul Anna-Lisa , Ferl Robert J. 
Published: April 2021

Abstract
The increasing availability of flights on suborbital rockets creates new avenues for the study of spaceflight effects on biological systems, particularly of the transitions between hypergravity and microgravity. This paper presents an initial comparison of the responses of Arabidopsis thaliana to suborbital and atmospheric parabolic flights as an important step toward characterizing these emerging suborbital platforms and their effects on biology. Transcriptomic profiling of the response of the Arabidopsis ecotype Wassilewskija (WS) to the aggregate suborbital spaceflight experiences in Blue Origin New Shepard and Virgin Galactic SpaceShipTwo revealed that the transcriptomic load induced by flight differed between the two flights, yet was biologically related to traditional parabolic flight responses. The sku5 skewing mutant and 14-3-3κ:GFP regulatory protein overexpression lines, flown in the Blue Origin and parabolic flights, respectively, each showed altered intra-platform responses compared to WS. An additional parabolic flight using the F-104 Starfighter showed that the response of 14-3-3κ:GFP to flight was modulated in a similar manner to the WS line. Despite the differing genotypes, experimental workflows, flight profiles, and platforms, differential gene expression linked to remodeling of central metabolic processes was commonly observed in the flight responses. However, the timing and directionality of differentially expressed genes involved in the conserved processes differed among the platforms. The processes included carbon and nitrogen metabolism, branched-chain amino acid degradation, and hypoxic responses. The data presented herein highlight the potential for various suborbital platforms to contribute insights into biological responses to spaceflight, and further suggest that in-flight fixation during suborbital experiments will enhance insights into responses during each phase of flight.

Shoot-out right
Authors: Janáč Viliam 
Published: April 2021

Summary
The article provides a basic analysis of the shoot-out right, in particular as regards the mechanism of its functioning. The shoot-out right is an instrument for handling of conflict situations in a company, where the exercise of this right is usually connected with exit of one of the shareholders and domination of the company by the remaining shareholder. At first sight, the shoot-out right is an elegant and fair solution for overcoming a shareholder conflict, which could threaten the very existence of the company. However, this right, and in particular its exercise, brings some risks.
