As transformações do trabalho na produção da cana-de-açúcar: a realidade entre o visível e o invisível
Authors: Barreto Maria Joseli , Thomaz Junior Antonio
Published: October 2020

No contexto de ampliação da tecnificação dos sistemas de colheita e plantio da cana-de-açúcar, procuramos ao longo desse texto, trazer reflexões sobre a organização, as condições e as relações sociais de trabalho diariamente vivenciadas pelos trabalhadores que laboram nos domínios do agrohidronegócio canavieiro, nas Regiões Administrativas de Presidente Pudente e Ribeirão Preto, isto é, buscamos desvendar a aparência do visível e a essência do invisível, nesse “novo” ambiente de trabalho. A partir da pesquisa, foi constatado que, por trás das inovações tecnológicas incorporadas à produção canavieira, existem novas e velhas formas de organização e controle do processo laboral, as quais remetem à superexploração do trabalho e, por conseguinte, aumentam a exposição dos trabalhadores aos riscos e agravos no ambiente de trabalho.

Published: October 2020

Este estudo se propõe mensurar o Índice de Desenvolvimento Rural (IDR) nos municípios cearenses e pernambucanos para o ano de 2010 e relacionar o IDR com o Produto Interno Bruto (PIB) agrícola e a população rural. Para mensurar o IDR, utilizou-se a técnica de análise fatorial e, para relacionar o IDR com o PIB agrícola e a população rural, empregou-se a correlação de Pearson. Os resultados revelaram expressiva heterogeneidade no desenvolvimento rural, em que, dos 330 municípios analisados, 56,36%, obtiveram um IDR baixo ou muito baixo e apenas 4,24% atingiram um IDR classificado como muitíssimo alto. No tocante à correlação, aferiu-se que as variáveis IDR e população rural estão fortemente correlacionadas, enquanto o IDR e PIB agrícola apresentaram moderada relação linear.
Drivers of cloud droplet number variability in the summertime in the southeastern United States

Published: October 2020

Abstract. Here we analyze regional-scale data collected on board the NOAA WP-3D aircraft during the 2013
Southeast Nexus (SENEX) campaign to study the aerosol–cloud droplet link and quantify the
sensitivity of droplet number to aerosol number, chemical composition, and vertical velocity. For
this, the observed aerosol size distributions, chemical composition, and vertical-velocity
distribution are introduced into a state-of-the-art cloud droplet parameterization to show that
cloud maximum supersaturations in the region range from 0.02 % to 0.52 %, with
an average of 0.14±0.05 %. Based on these low values of supersaturation, the
majority of activated droplets correspond to particles with a dry diameter of 90 nm and above.
An important finding is that the standard deviation of the vertical velocity
(σw) exhibits considerable diurnal variability (ranging from
0.16 m s−1 during nighttime to over 1.2 m s−1 during day), and it tends to
covary with total aerosol number (Na). This σw–Na
covariance amplifies the predicted response in cloud droplet number (Nd) to
Na increases by 3 to 5 times compared to expectations based on Na
changes alone. This amplified response is important given that droplet formation is often
velocity-limited and therefore should normally be insensitive to aerosol changes. We also find
that Nd cannot exceed a characteristic concentration that depends solely on
σw. Correct consideration of σw and its covariance with time
and Na is important for fully understanding aerosol–cloud interactions and the
magnitude of the aerosol indirect effect. Given that model assessments of aerosol–cloud–climate
interactions do not routinely evaluate for overall turbulence or its covariance with other
parameters, datasets and analyses such as the one presented here are of the highest priority to
address unresolved sources of hydrometeor variability, bias, and the response of droplet number to
aerosol perturbations.
Statistical moments of power spectrum: a fast tool for the classification of seismic events recorded on volcanoes
Authors: Galluzzo Danilo , Nardone Lucia , La Rocca Mario , Esposito Antonietta M. , Manzo Roberto , Di Maio Rosa
Published: October 2020

Abstract. Spectral analysis has been applied to almost thousand seismic events recorded at Vesuvius volcano (Naples, southern Italy) in 2018 with the aim to test a new tool for a fast event classification. We computed two spectral parameters, central frequency and shape factor, from the spectral moments of order 0, 1, and 2, for each event at seven seismic stations taking the mean among the three components of ground motion. The analyzed events consist of volcano-tectonic earthquakes, low frequency events and unclassified events (landslides, rockfall, thunders, quarry blasts, etc.). Most of them are of low magnitude, and/or low maximum signal amplitude, therefore the signal to noise ratio is very different between the low noise summit stations and the higher noise stations installed at low elevation around the volcano. The results of our analysis show that volcano-tectonic earthquakes and low frequency events are easily distinguishable through the spectral moments values, particularly at seismic stations closer to the epicenter. On the contrary, unclassified events show the spectral parameters values distributed in a broad range which overlap both the volcano-tectonic earthquakes and the low frequency events. Since the computation of spectral parameters is extremely easy and fast for a detected event, it may become an effective tool for event classification in observatory practice.
A 3D map of englacial attenuation rate from radar reflections at
Law Dome, East Antarctica
Authors: Abdul Salam Syed , Roberts Jason L. , McCormack Felicity S. , Coleman Richard , Halpin Jacqueline A.
Published: October 2020

Abstract. The East Antarctic Ice Sheet (EAIS) is the largest source of potential sea-level rise, containing approximately 52 m of sea-level equivalent. To constrain estimates of sea-level rise into the future requires knowledge of ice-sheet properties and geometry and ice-penetrating radar offers a means to estimate these properties (e.g. ice thickness, englacial temperatures). One of the regions that have been extensively surveyed using ice-penetrating radar from the Investigating the Cryospheric Evolution of the Central Antarctic Plate (ICECAP) project in East Antarctica is Law Dome, a small independent ice cap situated to the west of Totten Ice Shelf. The ice cap is slow-moving, has a low melt-rate at the surface and moderate wind speeds, making it a useful study site for estimating the radar attenuation. A new method is proposed for the estimation of attenuation rate from radar data which is mathematically modelled as a constrained regularised l2 minimisation problem. In the proposed method, only radar data is required and the englacial reflectors are automatically detected from the radar data itself. To validate our methodology, attenuation differences at flight crossover points are calculated and statistical analyses performed to assess the accuracy of the results. For spatial analyses, the errors are of the order 22.6 %, 15.2 %, and 32.8 % for mean absolute error, median absolute error, and root mean square error respectively. Also, for the depth analyses, up to the depth of 800 m, the errors are under 29.9 %, 24.2 %, and 38.8 % for mean absolute error, median absolute error, and root mean square error respectively. A final product of 3D attenuation rates and uncertainty estimates is provided. The generated dataset is publicly available at https://doi.org/10.25959/5e6851e266f4a (Abdul Salam, 2020).
Simulating human impacts on global water resources using VIC-5
Authors: Droppers Bram , Franssen Wietse H. P. , van Vliet Michelle T. H. , Nijssen Bart , Ludwig Fulco
Published: October 2020

Abstract. Questions related to historical and future water resources and scarcity have been addressed by several macroscale hydrological models. One of these
models is the Variable Infiltration Capacity (VIC) model. However, further model developments were needed to holistically assess anthropogenic
impacts on global water resources using VIC. Our study developed VIC-WUR, which extends the VIC model using (1) integrated routing, (2) surface and groundwater use for various sectors
(irrigation, domestic, industrial, energy, and livestock), (3) environmental flow requirements for both surface and groundwater systems, and (4) dam
operation. Global gridded datasets on sectoral demands were developed separately and used as an input for the VIC-WUR model. Simulated national water withdrawals were in line with reported
Food and Agriculture Organization (FAO) national annual withdrawals (adjusted R2 > 0.8), both per sector and per source. However, trends in time for domestic and industrial water withdrawal were mixed compared with previous studies. Gravity Recovery and Climate Experiment (GRACE) monthly terrestrial water storage anomalies were well represented (global mean root-mean-squared error, RMSE, values of 1.9 and 3.5 mm for annual and interannual anomalies
respectively), whereas groundwater depletion trends were overestimated. The implemented anthropogenic impact modules increased simulated streamflow
performance for 370 of the 462 anthropogenically impacted Global Runoff Data Centre (GRDC) monitoring stations, mostly due to the effects of reservoir operation. An assessment of
environmental flow requirements indicates that global water withdrawals have to be severely limited (by 39 %) to protect aquatic ecosystems,
especially with respect to groundwater withdrawals. VIC-WUR has potential for studying the impacts of climate change and anthropogenic developments on current and future water resources and sector-specific water scarcity. The additions presented here make the VIC model more suited for fully integrated worldwide water resource assessments.
Improved representation of river runoff in Estimating the
Circulation and Climate of the Ocean Version 4 (ECCOv4)
simulations: implementation, evaluation and impacts to
coastal plume regions
Authors: Feng Yang , Menemenlis Dimitris , Xue Huijie , Zhang Hong , Carroll Dustin , Du Yan , Wu Hui
Published: October 2020

Abstract. In this study, we improve the representation of global river runoff in the Estimating the Circulation and Climate of the Ocean (ECCO) framework, allowing for a more realistic treatment of coastal plume dynamics. We use a suite of experiments to explore the sensitivity of coastal plume regions to runoff forcing, model grid resolution, and grid type. The results show that simulated Sea-Surface Salinity (SSS) is reduced as the model grid resolution increases. Compared to Soil Moisture Active Passive (SMAP) observations, simulated SSS is closest to SMAP when using Daily, Point-source Runoff (DPR) and the intermediate resolution LLC270 grid. The Wilmott skill score, which quantifies agreement between models and observations, yields up to 0.92 for large rivers such as the Amazon. There was no major difference in SSS for tropical and temperate coastal rivers when the model grid type was changed from cube-sphere to latitude-longitude-polar-cap. We also found that using DPR forcing and increasing model resolution from the coarse resolution LLC90 grid to the intermediate resolution LLC270 grid elevates the river plume area, volume, and freshwater transport, along with stabilizing stratification and generally shoaling the mixed layer depth (MLD). Additionally, we find that the impacts of increasing model resolution from intermediate resolution LLC270 grid to high resolution LLC540 grid are regionally dependent. The Mississippi River Plume is more sensitive than others regions, possibly because the wider and shallower Texas-Louisiana shelf drives a stronger baroclinic effect, as well as relatively weak sub-grid vertical mixing and adjustment in this region. The results indicate that due to the complex bathymetry and dynamic behaviour of coastal environments, it may be challenging for spatially-unified resolution models to capture process-rich fidelity and obtain computational efficiency for coastal interfaces on a global scale. Our results offer a benchmark for representing Land-Ocean-Aquatic-Continuum (LOAC) processes in global models and data assimilation products and will help advance predictions of land-ocean-atmospheric feedbacks seamlessly in the next generation of earth system models.
Changes in detrital sediment supply to the central Yellow Sea since the last deglaciation
Authors: Koo Hyo Jin , Cho Hyen Goo
Published: October 2020

Abstract. The sediment supply to the central Yellow Sea since the
last deglaciation was uncovered through clay mineralogy and geochemical
analysis of core 11YS-PCL14 in the Central Yellow Sea Mud (CYSM). The core
can be divided into four units based on the various proxies, such as grain
size, clay mineralogy, geochemistry, and Sr and Nd isotopes: Unit 4 (700–520 cm; 15.5–14.8 ka), Unit 3 (520–310 cm; 14.8–12.8 ka), Unit 2 (310–130 cm;
12.8–8.8 ka), and Unit 1 (130–0 cm; <8.8 ka). Unit 2 is subdivided
into two subunits, Unit 2-2 (310–210 cm; 12.8–10.5 ka) and Unit 2-1 (210–130 cm; 10.5–8.8 ka), according to smectite content. Comparison of the clay
mineral compositions, rare earth elements, and εNd indicate
distinct provenance shifts in core 11YS-PCL14. Moreover, the integration of
clay mineralogical and geochemical indices show different origins according
to particle size. During the late last deglaciation (Units 3 and 4,
15.5–12.8 ka), Unit 4 sediments originated from all potential provenance
rivers, such as the Huanghe, Changjiang, and western Korean rivers, while the
source of coarse sediments changed to the Huanghe beginning with Unit 3.
Fine-grained sediment was still supplied from all rivers during the deposition
of Unit 3. Early Holocene (Unit 2) sediments were characterized by
oscillating grain size, clay minerals, and moderate εNd values.
In this period, the dominant fine-sediment provenance changed from the
Huanghe to the Changjiang, whereas coarse sediments most likely originated
from western Korean rivers. The Unit 1 CYSM sediments were sourced primarily
from the Changjiang, along with minor contributions from the western Korean
rivers. Possible transport mechanisms concerning such changes in the
sediment provenance include paleo-river pathways, tidal stress evolution,
and the development of the Yellow Sea Warm Current and coastal circulation
systems, depending on the sea level fluctuations.
Transversely Isotropic Lower Crust of Variscan Central Europe
imaged by Ambient Noise Tomography of the Bohemian Massif

Published: October 2020

Abstract. Recent development of ambient noise tomography, in combination with increasing number of permanent seismic stations and dense networks of temporary stations operated during passive seismic experiments, provides a unique opportunity to build the first high-resolution 3-D shear wave velocity (vS) model of the crust of the Bohemian Massif (BM). The velocity model with a cell size of 22 km is built by conventional two-step inversion approach from Rayleigh wave group velocity dispersion curves measured at more than 400 stations. The shear velocities within the upper crust of the BM are ~0.2 km s−1 higher than those in its surroundings. The highest crustal velocities appear in its southern part, the Moldanubian unit. The model provides compelling evidence for a regional-scale of velocity distribution. The Cadomian part of the region has a thinner crust, while the crust assembled, or tectonically transformed in the Variscan period, is thicker. The sharp Moho discontinuity preserves traces of its dynamic development expressed in remnants of Variscan subductions imprinted in bands of crustal thickenings. A significant feature of the presented model is the velocity drop interface (VDI) modelled in the lower part of the crust. We explain this feature by anisotropic fabric of the lower crust, which is characterized as vertical transverse isotropy with the low velocity being the symmetry axis. The VDI is often interrupted around the boundaries of the crustal units, usually above locally increased velocities in the lowermost crust. Due to the NW SE shortening of the crust and the late Variscan strike slip movements along the NE SW oriented sutures preserved in the BM lithosphere, the anisotropic fabric of the lower crust was partly or fully erased along the boundaries of original microplates. These weakened zones accompanied by a velocity increase above the Moho, which indicate an extrusion of mantle rocks into the lower crust, can represent channels through which portions of subducted and later molten rocks have percolated upwards providing magma to subsequently form granitoid plutons.
Change-point detection in wind turbine SCADA data for robust condition monitoring with normal behaviour models
Authors: Letzgus Simon
Published: October 2020

Abstract. Analysis of data from wind turbine supervisory control and data acquisition (SCADA) systems has attracted considerable research interest in recent years. Its predominant application is to monitor turbine condition without the need for additional sensing equipment. Most approaches apply semi-supervised anomaly detection methods, also called normal behaviour models, that require clean training data sets to establish healthy component baseline models. In practice, however, the presence of change points induced by malfunctions or maintenance actions poses a major challenge. Even though this problem is well described in literature, this contribution is the first to systematically evaluate and address the issue. A total of 600 signals from 33 turbines are analysed over an operational period of more than 2 years. During this time one-third of the signals were affected by change points, which highlights the necessity of an automated detection method. Kernel-based change-point detection methods have shown promising results in similar settings. We, therefore, introduce an appropriate SCADA data preprocessing procedure to ensure their feasibility and conduct comprehensive comparisons across several hyperparameter choices. The results show that the combination of Laplace kernels with a newly introduced bandwidth and regularisation-penalty selection heuristic robustly outperforms existing methods. More than 90 % of the signals were classified correctly regarding the presence or absence of change points, resulting in an F1 score of 0.86. For an automated change-point-free sequence selection, the most severe 60 % of all change points (CPs) could be automatically removed with a precision of more than 0.96 and therefore without any significant loss of training data. These results indicate that the algorithm can be a meaningful step towards automated SCADA data preprocessing, which is key for data-driven methods to reach their full potential. The algorithm is open source and its implementation in Python is publicly available.

El presente trabajo se propone analizar el debate entre Žižek y Butler a propósito de la cuestión de la diferencia sexual. Para ello, en primer lugar, trataremos de definir, a través de una reconstrucción del marco teórico, las tradiciones de pensamiento feminista de las que son herederos. En segundo lugar, se tratará de señalar los puntos de divergencia y convergencia entre ambas posiciones, la una ontológica y la otra constructivista, para finalmente mostrar el campo problemático común a ambos que permite articular una perspectiva feminista, alejada de los clásicos enfrentamientos entre ontología y biopolítica.
RECONSIDERANDO A TESE DA PENALIDADE NEOLIBERAL: INCLUSÃO SOCIAL E ENCARCERAMENTO EM MASSA NO BRASIL
Authors: Dal Santo Luiz Phelipe
Published: October 2020

Com base na teoria de Loïc Wacquant, o neoliberalismo tem sido a principal categoria explicativa relacionada à expansão do sistema penal e ao endurecimento das penas, notados a partir dos anos 1970, nos Estados Unidos, e da década seguinte, em diversos países na Europa. Embora inicialmente formulada para lidar com as transformações no sistema de justiça criminal estadunidense, a “penalidade neoliberal” é frequentemente incorporada ao discurso criminológico brasileiro na tentativa de compreender o encarceramento em massa no Brasil. No entanto, as transformações político-econômicas e sociais verificadas em um considerável período do século XXI no país sul-americano são aparentemente ignoradas na literatura criminológica nacional contemporânea. Não por outra razão, por meio de análise de dados secundários referentes à variação de indicadores socioeconômicos – como o IDH, o Índice de GINI e a taxa de desemprego – e do investimento público em distintos setores, o presente artigo identifica limitações para a “importação” da teoria da penalidade neoliberal enquanto teoria capaz de explicar integralmente a contínua expansão do sistema penal brasileiro em tempos de inclusão social.
Advanced neoplasia detection using chromoendoscopy and white light colonoscopy for surveillance in patients with inflammatory bowel disease
Authors: Kim Kyeong Ok , Chiorean Michael V.
Published: October 2020

Background/Aims: Chromoendoscopy (CE) has been shown to be superior to white light endoscopy (WLE) for neoplasia detection in inflammatory bowel disease (IBD). We aimed to compare the yield of CE and WLE for the detection of overall neoplasia and advanced neoplasia in IBD. Methods: Patients who underwent surveillance colonoscopy from 1999 to 2017 were identified from our IBD database. CE procedures were compared with their respective WLE controls in a paired comparison, and frequency of all neoplasia, advanced neoplasia, and serrated neoplasia was assessed for both targeted and random biopsies.Results: A total of 290 procedures performed in 98 individuals were identified with a median follow-up 4 years (median 3 colonoscopies/patient). CE and WLE were performed in 159 and 131 episodes, respectively. CE detected neoplasia in 40.9% of colonoscopies versus 23.7% with WLE (P= 0.002). In addition, CE detected more advanced neoplasia (18.2% vs. 6.1%, P= 0.002) and serrated lesions (14.5% vs. 6.1%, P= 0.022). Significantly fewer samples were obtained per procedure with CE (14.9 ± 9.7 vs. 20.9 ± 11.1, P< 0.001). Cancer was diagnosed in 2 cases.Conclusions: CE has a higher detection rate than WLE for advanced neoplasia and serrated lesions in patients with IBD under surveillance. Further prospective studies evaluating the impact of CE on decreasing the risk of interval cancer and colectomy in IBD patients are warranted.

Aim of study: To validate two existing single nucleotide polymorphism (SNP) panels for parentage assignment in sheep, and develop a cost effective genotyping system to use in some North-Eastern Spanish meat sheep populations for accurate pedigree assignment.Area of study: SpainMaterial and methods: Nine sheep breeds were sampled: Rasa Aragonesa (n=38), Navarra (n=39), Ansotana (n=41), Xisqueta (n=41), Churra Tensina (n=38), Maellana (39), Roya Bilbilitana (n=24), Ojinegra (n=36) and Cartera (n=39), and these animals were genotyped with the Illumina OvineSNP50 BeadChip array. Genotypes were extracted from the sets of 249 SNPs and 163 SNPs for parentage assignment designed in France and North America, respectively. Validation of a selected cost-effective genotyping panel of 158 SNPs from the French panel were performed by Kompetitive allele specific PCR (KASP). Additionally, some functional SNPs (n=15) were also genotyped.Main results: The set of 249 SNPs for parentage assignment showed better diversity, probability of identity, and exclusion probabilities than the set of 163 SNPs. The average minor allele frequency for the set of 249, 163 and 158 SNPs were 0.41 + 0.01, 0.39 + 0.01 and 0.42 + 0.01, respectively. The parentage assignment rate was highly dependent to the percentage of putative sires genotyped.Research highlights: The described method is a cost-effective genotyping system combining the genotyping of SNPs for the parentage assignment with some functional SNPs, which was successfully used in some Spanish meat sheep breeds.

Authors: hilali Wail El , El manouar Abdellah , Janati Idrissi Mohammed Abdou
Published: October 2020

In these challenging times, finding a way to sustain the created value becomes a must. The fierce competition, the risk of disruption, the rise of customer awareness and the scarcity of resources, all these are few of many drivers that push companies to invest in sustainability. This paper is an attempt to enrich the literature about this subject. It mainly explores how to use the AHP method, a well-known multicriteria decision making technique, to decide about the right actions to implement, in order to reach sustainability. The paper is a continuity of a previous work that introduced a new framework that explained how companies could sustain their business models through information systems (IS). This approach was applied on a telecom operator, as a case study, to explain well how companies could choose the right actions to implement, in order to reach sustainability.

Authors: Leshe Sintayehu , Baye Habitamu
Published: October 2020

The use of Acanthus pubescens flower extracts as natural eco-friendly substitutes for synthetic acid - base indicators is experimentally confirmed. In this study, it is indicated that ethanolic and acidified ethanol extracts of Acanthus pubescens flower are good replacements to phenolphthalein, bromothymol blue and methyl red in acid-base titrations involving a strong acid versus strong base and a strong acid versus weak base. They can also be used as effective substitutes to phenolphthalein in a weak acid versus strong base titrations. And also the acidified ethanol extracts can be used in place of phenolphthalein and bromothymol blue while the ethanol extracts can replace methyl red in weak acid versus weak base titrations. It is also concluded that the use of Acanthus pubescens flower extract as an indicator in all types of acid base titrations is beneficial because of its economy, eco-friendly nature, ease of preparation, availability, simplicity, non-carcinogenicity, precision and accuracy of results.

Se clasificó la cobertura de tres imágenes satelitales Landsat (P030 y R046) de los años 1990 (Sensor TM), 2003 y 2013 (Sensor ETM) con el software SIG Arc Gis 10 (ESRI, 2008)®. Y se generaron mapas temáticos con cuatro clases de cobertura, con una fiabilidad del 75%, el 78% y el 86%, y estimaciones del coeficiente Kappa de 0,61, 0,67 y 0,80, respectivamente. Estos mapas fueron comparados mediante matrices de error, donde se registraron procesos evidentes, como el cambio de cobertura en espacios destinados a actividades agrícolas. La tasa de cambio fue del 0,99% para el bosque templado de coníferas y latifoliadas; el bosque tropical subcaducifolio registró el 1,02%, y las zonas agrícolas, el 1,08%, respecto a la superficie total de la cuenca. Las zonas urbanas no mostraron cambios en el periodo analizado, y se considera que esto se debe a las condiciones topográficas de la cuenca del río Cuale.
La cultura como estrategia de regeneración urbana en Monterrey, México
Authors: Garza-Rodríguez Fabiola R. , Ramírez-Agudelo Nancy Andrea , Roca Bosch Elisabet , Villares Junyent Míriam
Published: October 2020

La cultura se ha utilizado como estrategia de regeneración urbana por su permeabilidad hacia otras áreas del desarrollo. Desde hace más de 30 años, el centro de Monterrey ha experimentado deterioro, pérdida de población y abandono, con lo que la estrategia del sector público ha sido realizar proyectos de regeneración urbana con fuerte implicación cultural. A pesar de la magnitud y la inversión de los proyectos, no se han logrado los objetivos esperados. En cambio, a partir del año 2013 surgen proyectos desde iniciativas bottom-up que están transformando positivamente el lugar. Se analizan los proyectos de regeneración urbana implementados en el centro mediante entrevistas a actores clave. Entre los principales resultados, destacan las iniciativas bottom-up como procesos de regeneración cultural capaces de transformar el territorio y el tejido social. La falta de diálogo entre actores es uno de los principales obstáculos para producir transformaciones más contundentes en el contexto sociourbano.

Authors: Świszczewska Maja , Wójcik Ewa , Kaproń Marian
Published: October 2020

A survey was conducted among users of horses from various parts of Poland to investigate their preferences regarding the basic behavioural characteristics of horses used in recreation and sport and to determine the importance of their main external and internal traits. The majority of respondents were women, and the largest age group was 21-25. The respondents most often chose geldings for use, due to their composure. The preferred age range was 6 to 10 years, with a height at the withers from 151 to 170 cm. The breed and external appearance of horses did not matter to most respondents, although they preferred Malopolski, Wielkopolski, and Polish Half-Bred horses. It was important to the survey participants for the horse to meet specific skill requirements and to have suitable traits for them, with no bad habits or stereotypic behaviours. Over 60% of respondents would like to buy their own horse. As many as 86% were very experienced riders who had been training and taking part in competitions for over 6 years, with 55% of the subjects training jumping and 40% dressage. Sixty-three per cent of respondents ride horses 3-4 days a week or every day.

Comparison of eight Polish translations of the fi nal segment of the Epilogue in William Shakespeare’s
The Tempest reveals an essential diversifi cation in the contents of these translated versions.
The differences appear in the identity of Prospero and in the discursive structure of his monologue.
This article attempts to describe this diversifi cation with the use of the categories of acts and genres
of speech, since it is these that form the ‘construction material’ of utterances, including literary texts,
creating diverse confi gurations in them. These categories of description, enabling insight into compositional
actions done on simple forms of discourse, elevates the analysis of translation practices
and consideration of the issue of equivalence of translation to a higher level of text organisation.
The Bulgarian Reception of Jerzy Liebert: Bringing Him Out of the Shadows
Authors: Grigorova Margreta
Published: October 2020

The article is structured as follows: its fi rst part is a review of the Bulgarian reception of Jerzy
Liebert (until 2018), while the second focuses on new results (2018–2019). Emphasis is placed
on the only translations of two poems by Liebert, which are included in The Modern Polish Poets anthology, published in 1967, – Foxes (Lisy) and Jurgov Pub (Jurgowska karczma). These
were translated by one of Bulgaria’s best poets and translators, Parvan Stefanov. He belongs
to the generation of so called “quiet lyric poetry” in Bulgarian literature, which mounts a lyrical
opposition to the propagandist and ideologised poetry from the time of the communist regime.
The amplifi cation of the reception of Liebert was actually the result of a voluminous Polish issue
of Bulgaria’s leading Literary Newspaper titled “Polish Literature between the Two World Wars”
(34/2018). This issue contains two new translations of poems by Liebert (The Rider/Jeździec, Love
Verse/Wiersz miłosny) and the fi rst translated article on Liebert published in Bulgaria: Jerzy Liebert
– The Ordinary Poet by Anna Marta Szczepan-Wojnarska. The subsequent corrections of the Bulgarian translation receptions of Liebert appear in the second and expanded edition (June 2019)
of the anthology Polish Poetry between the Wars (ed. by Panayot Karagyozov), where a total fi ve
new translations were: the aforementioned The Rider and Love and Verse I Learn from You, Human
(Uczę się Ciebie, człowieku), The Beginning of Autumn (Początek jesieni), Snow (Śnieg). The new
translations are by the author of this article.
Miguel de Unamuno’s Anthropological Theses
– From Tragedy to Transcendence
Authors: Gołębiewska Maria
Published: October 2020

The aim of the text is to provide a preliminary discussion of the assumptions and anthropological theses in Miguel de Unamuno’s philosophy, mainly because of his best-known book from 1912
Del sentimiento trágico de la vida (Tragic Sense of Life). Unamuno’s extensive deliberations can
be considered in many contexts: ontological, epistemological, ethical and axiological. However,
anthropological theses seem to be dominant in his thoughts. In Unamuno’s anthropological theses,
especially in his affi rmation of human existence, it is easy to see references to religious thought and
theology (Catholic and Protestant). Unamuno infl uenced the further development of philosophy
and his theses can be considered as a presentation of the main philosophical problems of the 20th
century: the identity of the individual, the sense of existence, the individualisation of life goals and
choices, freedom as a task facing the individual, the impermanence of norms and the search for
lasting values, senses and meanings. It is easy to notice that what makes Unamuno’s theses stand
out is the anthropocentrism of his theses, i.e. the belief in the original – in an ontological sense
– essence of humanity. Unamuno, in his anthropological theses, captures the essence and existence
of humanity, but the starting point is always the concrete, individual human being and its existence. In characterising humans, Unamuno describes the human effort and desire for immortality,
adopts the assumptions of historical relativism, referring at the same time to the permanent and
unchanging sphere of transcendence. He assumes an inherently diverse human being, which is
internally contradictory. This internal contradiction results in different anthropologies, but also in
a differentiated identity of the individual. The tragic character of the mundane existence relates to
the irremovable aporias of the spiritual and the material in humans, as well as reason and will,
aspiration and inability. Faith in God is the decisive element in the tragic existence of humans, which
is nevertheless affi rmed by Unamuno. It is this existence in a mundane form that we wish to preserve
through immortality and our way towards transcendence.
Multiparty Call Control at the Network Edge

Published: October 2020

Network programmability is a key feature of fifth generation (5G) system which, in combination with cloud-based services, can support many use cases, including mission critical and healthcare communications. Programmability enables flexibility in customization of service connectivity. Multi-access Edge Computing (MEC) services and applications are enablers for network programmability. In this paper, MEC capabilities for programmability of multiparty multimedia call control at the network edge are studied. Multiparty video calls are one of the key applications of 5G, and are efficient way to exchange ideas, knowledge, expertise, information, and so on. The paper presents an approach to design MEC Application Programming Interfaces (APIs) which enable third party applications to create multiparty multimedia sessions and dynamically manage session participations. The API functionality is described by required information and message flows. The paper specifies the proposed MEC API with data model. Feasibility study includes modelling and formal validation of multiparty session state models supported by the network and mobile edge application. The latency injected by the API is evaluated by emulation.
Novel Composite Approximation for the Gaussian Q-Function

Published: October 2020

This paper, by using Borjesson’s and Benitez’s approximation of Q-function, presents a novel and improved composite approximation of Q-function with wide applicability. The presented approach is very general and can be implemented on any observed interval. Based on the proposed approximation of Q-function, the average bit error rate is assessed by observing the transfer over Nakagami-m fading channel. The simplicity of the proposed approximation form in conjunction with yet another feature - utmost accurateness - appeared to be a better choice than the suggested approximations of similar complexity in terms of analyticity. The paper emphasizes the wide implementation possibilities in numerous tasks of communication theory and functional analysis that include Q-function.
The Politics of Knowledge Organization: Introduction to the Special Issue
Authors: Leazer Gregory H. , Montoya Robert
Published: October 2020

Politics is about the distribution of goods and risks. We can describe the distribution of goods, and we can also characterize those distributions as a kind of inequality. As a baseline definition of “politics of information” we mean the distribution of information goods across different populations. Despite a strong tradition of disciplinary focus in information science, much of the literature is still given over to fairly simple notions of social form and structure. A nascent knowledge organization practice dedicated to social difference is explicitly motivated by justice and nomenclature. Not only is knowledge organization a tool of cultural hegemony, but also it can be read as a product of cultural ordering and bias. Identifying unjust and politically oppressive practice must be part of the path to justice. Understanding the political construction of knowledge organization is essential for the theory of information service in order to build a more just professional practice.
Centering Relationality: A Conceptual Model to Advance Indigenous Knowledge Organization Practices
Authors: Littletree Sandra , and Miranda Belarde-Lewis , Duarte Marisa
Published: October 2020

Scholars and practitioners have exposed the limitations of traditional Euro-American approaches to knowledge organization (KO) when it comes to Indigenous topics. To develop more effective KO practices, there is a need for KO practitioners to understand Indigenous perspectives at an epistemological level. A theoretically-informed model of Indigenous systems of knowledge serves as a pedagogical tool to support the labor of boundary-spanning and code-switching between Euro-American KO practices and Indigenous KO practices.
Sokratische oder sophistische Selbstführung – eine notwendige Unterscheidung
Authors: Dietz Karl-Martin
Published: October 2020

Unter »Selbstführung« werden heute bei näherer Hinsicht zwei verschiedene Dinge verstanden: zum einen so etwas wie »Selbstoptimierung«, d. h. quantitative Leistungssteigerung, deren Ziele undiskutiert dem neoliberalen Denkmuster entnommen werden. Davon zu unterscheiden ist zum anderen eine Art von Selbstführung, bei der der Einzelne auch die Zielrichtung seines Handelns bewusst bestimmt (Selbstorientierung). Der unterschiedliche Charakter dieser beiden Arten der Selbstführung wird als Konsequenz einer Weichenstellung des europäischen Denkens im 5. Jahrhundert v. Chr. zwischen der sokratischen und der sophistischen Denkrichtung erläutert. Vor diesem Hintergrund werden die beiden heute geltenden Auffassungen von »Selbstführung« differenziert und erörtert. Die Mehrzahl der Führungslehren scheint dem sophistischen Muster zu folgen; als Beispiel für das sokratische Denkmuster wird die Dialogische Führung/Dialogische Kultur vorgestellt, wie sie am Hardenberg Institut seit ca. 30 Jahren entwickelt wird.
Ok, Boomer: Generationenkonflikte in Anwaltskanzleien
Authors: Ziercke Emma , Hartung Markus
Published: October 2020

In vielen Veröffentlichungen wird geäußert, dass Generationsunterschiede eine Quelle von Konflikten in Anwaltskanzleien seien. Die Verwendung von Klassifikationen (»Generation Y«) und Stereotypen (»Generation Y ist faul und anmaßend«) führt zu der Wahrnehmung, dass die Generationen unterschiedliche Werte und Arbeitseinstellungen haben und dass diese Unterschiede eine Quelle für zwischenmenschliche Konflikte am Arbeitsplatz seien. Wir meinen hingegen, dass unabhängig davon, ob die Unterschiede zwischen den Generationen real sind oder nicht, die Konflikte nicht auf die Generationsunterschiede an sich zurückzuführen sind, sondern darauf, dass die ältere Generation von Jurist*innen mit »Change« konfrontiert wird. Die von den »Millennial Lawyers« eingeläuteten Veränderungen stellen viele Werte und Überzeugungen in Frage, mit denen ältere Anwält*innen aufgewachsen sind. Diese bilden auch das Fundament der Organisationskultur von Anwaltskanzleien.
Generationenübergreifendes Engagement und die Förderung von Empathie
Authors: Schütt Svenja Christina , Kals Elisabeth
Published: October 2020

In unserer sich stetig wandelnden Gesellschaft stehen Generationenbeziehungen vor großen Herausforderungen wie der Digitalisierung oder der Entfremdung durch zunehmende Mobilität. Freiwilligenprojekte, welche den außer-familiären Austausch von Generationen fördern, etablieren sich in Deutschland, jedoch gibt es in diesem Feld bisher kaum Forschung. Die vorliegende Studie (N = 361) untersucht, inwieweit generationenübergreifende Engagements in Zusammenhang mit Empathie für andere Generationen stehen. Die Befunde zeigen, dass generationenübergreifend Engagierte mehr Empathie für andere Generationen empfinden als die Vergleichsgruppen. Positive Erlebnisse mit anderen Generationen im Engagement, wie erlebte Wertschätzung, positiv erlebte Kontaktqualität sowie generationenübergreifendes Lernen, nehmen Einfluss auf das empathische Erleben. Dagegen erweist sich das Problembewusstsein für gesellschaftliche Generationenbeziehungen oder der Generationenkontakt innerhalb der Familie als nicht bedeutsam für die Erklärung von Empathie für andere Generationen.
