Openness or Prejudice?: Students’ Attitudes to Refugees in Poland
Authors:   University of Bialystok, Faculty of Education, Danilewicz Wioleta
Published: February 2021

This paper aims to present a study into student teachers’ and social workers’ attitudes towards refugees in Poland. Based upon survey data, it explores three categories of respondents’ attitudes towards refugees in Poland: ‘positive,’ ‘ambivalent,’ and ‘negative’. Overall, the ﬁndings of this study reveal a very worrying trend – almost half of the participants (46%) demonstrated a negative position on accepting refugees into the country, indicating that they believe refugees possess a threat for both society as a whole and their own personal security. This paper concludes that teacher preparation and professional development are essential building blocks in developing more positive attitudes not only towards refugees, but also other minority social groups in Poland.

Los documentos recopilados resumen los ensayos de investigación realizados en Galicia que en primer lugar, pueden servir de base para facilitar las futuras investigaciones sobre resinación que se realicen en el noroeste de la Península Ibérica, y en segundo lugar, aportar unos primeros fundamentos que permitan desarrollar una selvicultura que compatibilice la extracción complementaria de resina con el aprovechamiento de la madera en el pino pinaster en Galicia.
Aportacións sobre a tipoloxía e composición florística dos bosques mesófilos de quercíneas do occidente da Cornixa Cantábrica (NW?Ibérico)
Authors: Rodríguez Guitián Manuel Antonio

Realízase unha revisión da tipoloxía fitosociolóxica das formacións arboradas dominadas por especies do xénero Quercus existentes no extremo setentrional de Galicia e o NW de Asturias a partir da revisión da información existente e da aportada nunha mostraxe de 183 novas localidades. Aínda que se mantén a inclusión dos bosques maioritarios deste territorio na asociación Blechno spicant-Quercetum roboris, reinterprétase o número e xerarquía das unidades de rango inferior (subasociacións, variantes, facies, fases) neles identificadas. Ademáis, dase a coñecer a existencia de carballais termófilos galaico-portugueses (as. Rusco aculeati-Quercetum roboris) en diversas localidades da área de estudo situadas entre a desembocadura do Río Eume (A Coruña) e O Valadouro (Lugo), así como a de reboleiras con carballo (as. Lonicero periclymeni-Quercetum pyrenaicae) nas cunca media e alta do río Eo, diversos tributarios pola esquerda do Río Navia e no tramo medio do Río Narcea. Por último, considérase necesario aportar máis datos para clarificar a entidade sintaxonómica dos carballais existentes ao longo das cuncas altas dos ríos Miño, Mandeo e Tambre. A reinterpretación proposta eleva de un a tres (catro?) a variedade de asociacións de bosques de quercíneas mesófilas existentes na área de estudio, o que supón un considerable incremento da diversidade fitocenótica arbórea recoñecida nesta unidade bioxeográfica.

Sororidad como estrategia de prevención de la violencia basada en género
Authors: Magda Alejandra Alonso Rodríguez , Lesly Marilyn Carrillo Quevedo , Yessica Dayanne Martínez Ardila
Published: February 2021

Este trabajo de investigación se realizó con el fin de analizar las relaciones sororales en las narrativas de mujeres que han experimentado la violencia basada en género (VBG) de manera personal, impersonal o colectivamente en la ciudad de Villavicencio; se apoya desde el paradigma interpretativo y de orden cualitativo, tomando como metodología la hermenéutica; como estrategias para la recolección de datos se aplicó de forma colectiva un mapa de red y un grupo focal, posteriormente se realizó una entrevista semiestructurada de manera individual, a un grupo de 4 mujeres con experiencia en violencia basada en género, de manera directa o indirecta. Como resultados se obtuvo 12 subcategorías, 4 (Crianza con ideología Patriarcal, naturalizar, amor propio y dolor emocional) correspondientes a la categoría de VBG y 7 (feminismo, redes sociales, empoderamiento, empatía, estereotipo, reconocimiento del otro y motivaciones) correspondientes a la categoría de sororidad. Para finalizar, a partir de las narrativas de las participantes se concluyó que el rol de la mujer establecido socialmente se rige a partir de las creencias y de la cultura, por lo cual dicha concepción del rol femenino se hereda generacionalmente y constituye un significado único de la mujer que influye y mantiene la violencia basada en género, también se pudo evidenciar que las participantes perciben las prácticas sororas como estrategia importante para la prevención de la VBG, sin embargo, es necesario fortalecer estas prácticas, teniendo en cuenta que muchas mujeres viven en medio de una sociedad ligada a una cultura y pensamientos patriarcales.

Rasgos genéticos poblacionales aclaran el estatus taxonómico del narciso de Villafuerte y respaldan su conservación
Authors: Medrano Mónica , Robles Jesús , Herrera Carlos M.
Published: February 2021

Correct delimitation of taxonomic entities is essential in conservation biology and methods based on population geneticscan be particularly helpful where other tools fail to provide reliable conclusions. In this paper we use population genetics and AFLP markers to elucidate the taxonomic status of the enigmatic Villafuerte daffodil (Narcissus enemeritoi (Sánchez-Gómez et al.), a taxon known from a single, small population in southeastern Spain whose position within the complex Pseudonarcissus section of the genus Narcissus has proven elusive so far. Compared to populations from other four southeastern Spanish taxa, the Villafuerte daffodil population was genetically indistinguishable from Narcissus nevadensis subsp. longispathus (Degen and Hervier ex Pugsley) Algarra, Blanca, Cueto and Fuentes. Genetic diversity and singularity of its single population were unexpectedly high. Despite losing its taxonomic distinctiveness after being subsumed by the relatively abundant N. n. subsp. longispathus, genetic singularity and diversity of Villafuerte daffodil still justify continuation of current conservation efforts.
Weathering performance of dyed bamboo fiber composites
Authors: Hu Yu'an , He Sheng , He Mei , Semple Kate , Chen Meiling , Dai Chunping
Published: February 2021

Flattened and crushed fiber-bundles of moso bamboo (Phyllostachys pubescens) were dyed with a water or alcohol-based dye at 20 °C, 75 °C or 90 °C for 72 h, followed by drying and coating with PF resin. Hot-pressed bamboo fiber composites (BFC) were manufactured, and the weathering performance of the composites made from dyed and natural bamboo material were tested over 90 days of the Autumn/Winter season in Beijing. Dye was able to penetrate the bamboo tissue to create a rich red color that degraded in color faster than BFC made from un-dyed bamboo. BFC made from un-dyed tissue remained a lighter but more consistent color over the weathering period. Dying the bamboo in ethanol-based dye was effective at pigmenting the product, but made it more susceptible to color degradation as well as greater mass and thickness loss due to the chemical degradation of the lignin caused by ethanol. Higher temperature of water dying treatment (90 °C) gave the greatest resistance to mass and thickness loss during outdoor exposure, and the bamboo may have benefitted from the longer period of ‘heat treatment’ during dyeing. Further work is needed to quantify dye leaching from bamboo tissue and to develop more water-tight and color-fast, weather resistant dyes for bamboo products.

The scope of criminal liability for misappropriation of authorship in EU countries: comparative analysis
Authors: Steponavičiūtė Ramunė
Published: February 2021

Intellectual property legal protection is undoubtedly one of the most important factors and conditions of effective economic, social and cultural development in modern society. According to researchers, absolute majority of countries in the world have set criminal liability for certain crimes against intellectual property rights, including all of the European Union (hereinafter – EU) countries. One of those crimes is misappropriation of authorship. Yet the criminal laws of EU countries criminalise misappropriation of authorship very differently - some protect not only author rights but also related rights, the conditions for criminal liability in the general corpus delicti are of a very different scope as well as the punishments for those crimes differ significantly. This analysis will present the scope of criminal liability in all the EU countries, including the reasons why, as well as will try to find the answer whether ways of coping with these difficulties exist.

By analysing the EU primary, secondary and Lithuanian (national) legislation, as well as the case law of European and Lithuanian judicial authorities, the insights into future challenges for both the EU and Lithuanian law are provided. It is being claimed that the EU is moving towards codification and strengthening of procedural rights, which inevitably influences Lithuanian legal system and the protection of individuals, inter alia legal persons.
Free movement of data in the European Union: opportunity or big challenge in a use of artificial intelligence?
Authors: Breskienė Ineta
Published: February 2021

This article analyses the current situation in the European Union related to the free movement of data, relationship between personal data, non – personal data and their use in artificial intelligence technology. Despite the European Union’s efforts to facilitate the free movement of data, some relevant obstacles are currently being observed. Artificial intelligence technology faces difficulties in using data. Despite the fact that large amounts of data are now increasingly accessible to such technology, its ability to de-anonymize data poses risks of turning simple data into personal data and making its use a challenge for artificial intelligence developers. The issues raised are sensitive and some regulatory changes should be made in the near future in order for the European Union to remain a leader in emerging technologies.
Does the EU have a substitute for a constitution? The rule of law and common identity
Authors: Kolczyńska Magdalena
Published: February 2021

Constitution, like no other legal act, is the manifestation of what a community thinks of itself; what are its aims, values and priorities. But what if this common source of identity is lacking? Can a body politic exist without constitution? If yes – does it come at certain price?Over a decade after the failure of a constitutional project for Europe I would like to ask whether EU has any substitute for the constitution for the following 10 years. I will consider that questions from two different standpoints – the rule of law and common European identity. First, I will ask whether existing legal order of EU needs the constitution to be consistent with the rule of law principle. This question was of great importance in Poland, as this decade started in our country with the EU triggering Article 7 of the Treaty of EU with the charge of breaching by Polish government the principle in question.The recent events however have drastically changed the situation in European Community. The observance of the rule of law does not seem enough for EU to assert its legitimacy in the course of the ongoing turmoil caused by the pandemic. What is needed is unprecedent solidarity among European Citizens – solidarity which transgress the demands of mere justice. I will claim that to maintain solidarity a common identity may be necessary. Thus, I will ask whether the constitution is necessary for the forming of European identity and whether it would be enough to achieve this aim.

The article presents the scientific achievements of researchers of the Institute of Animal Biology NAAS in reproductive biotechnology in sheep breeding. The Ukrainian-Polish experiment on improving the in vitro method of sheep fertilization, which ended with the birth of the first lamb in Ukraine, is covered in detail. The scientific achievements of the staff of the institute were the basis for the introduction of an improved method of laparoscopic insemination of sheep in Ukrainian farms. Laparoscopic insemination of local breeds of sheep of Lviv, Zakarpattia, Kherson and Dnipropetrovsk regions with sperm of sheep of specialized fat breeds was carried out and fertilization of more than 80% was obtained. Also, scientific and practical work was carried out to improve and implement methods of stimulating superovulation in ewes of the Texel breed, non-surgical washing of embryos and their transplantation to bright recipients of the Ukrainian Carpathian breed.

The article presents the data of the effect of different doses of pyridoxine hydrochloride on the activity of humoral immunity in the blood serum of calves of the dairy growing period. The lowest activity of the indicators of humoral immunity was found in the serum of calves for the first day of life in all research groups. Exogenous administration of pyridoxine hydrochloride to colostrum and milk led to changes in the studied parameters. It was found that the bactericidal activity of serum increases on the 21st day of calf life and slightly decreases on the 90th day. The addition of pyridoxine hydrochloride at different doses to the milk leads to a probable increase in bactericidal activity of the serum only at doses of 4.0 mg/kg body weight at 60 and 90 days (P<0.05) and 5.0 mg/kg body weight from 21 90 days (P<0.05). Serum lysozyme activity increases during ontogeny and under the action of exogenous pyridoxine hydrochloride. A significant difference between the lysozyme activity indices of the control and experimental groups was established in calves of II, III, IV and V groups on the 60th and 90th day (P<0.05, P<0.01). Complementary activity of serum increases during ontogenesis, and additional introduction of pyridoxine hydrochloride has led to its decrease. A significant decrease in the complementary activity of serum was detected in calves at doses of 4 mg/kg body weight on the 90th day (P<0.05) and 5 mg/kg body weight from 21st to 90th day (P<0.05, P<0.01).

Si-CN films exhibit high mechanical and optoelectronic properties such as photoconductivity, photoluminescence, variable energy gap in the range of 1.37-5.2 eV, high mechanical and thermal strength, low thermal expansion, which allows them to be used in semiconductor devices. and in microelectronic mechanical systems. They are obtained by chemical deposition methods, and to activate the reaction using thermal heating, plasma or ultraviolet radiation, and by physical methods of deposition at relatively low temperatures by magnetron sputtering. The structure of the films can vary from microcrystalline to amorphous, the main influence being the deposition temperature. Chemical bonding in films is carried out mainly due to the interaction of Si-N, Si-C, C-C, C-N. Despite a significant amount of experimental work to study the properties of Si-C-N films, there are virtually no studies of films deposited by plasma chemical methods using hexamethyldisilazane as the main precursor. The review analyzes the influence of the main parameters of plasma chemical deposition, such as substrate temperature, reagent flow rate, high-frequency discharge power and displacement on the substrate on the physical properties of the films. It is shown that the main mechanism of transport of charge carriers in the investigated films is the space charge limited current. Based on electrical measurements, a number of band parameters as well as parameters of deep traps in a-SiCN films were estimated for the first time.
INFLUENCE OF LOCAL MECHANICAL STRESSES ON THE SILICON SPUTTERING YIELD BY ION BEAM

A review of scientific publications and modeling of the effect of mechanical stresses on the sputtering yield of silicon by an ion beam is carried out. It is shown that the flux of atoms (from the depth to the surface) through interstitial or vacancy mechanisms due to the stress gradient caused by the limiting bending of the plate is insufficient to explain the increase in the sputtering coefficient. Calculations show that even the limiting elastic deformations do not significantly change the energy of atom detachment from the site, and an increase in the drift velocity of atoms due to the enrichment of the near-surface region with vacancies is insufficient to increase the sputtering rate. Consequently, it is necessary that the elastic deformation is transformed into plastic with the formation of mobile weakly bound atoms. The calculated stress distribution in a loaded silicon wafer using the COMSOL Multiphysics software package showed that the key driving force behind the increase in the silicon sputtering coefficient is the concentration of compressive and tensile stresses in the vicinity of the simulated crater during sputtering. The created crater is a stress concentrator, the gradients of which significantly exceed the values obtained by bending a plate without a crater. It is demonstrated that the generated stresses exceed the ultimate strength of the material in the vicinity of the crater, which begins to relax due to the expulsion of "excess" atoms in the tension region. The appearance of additional deformation-stimulated fluxes of weakly bound surface atoms at the bottom and walls of the crater provides an increase in the concentration of knocked-out atoms in the process of ion sputtering. Simulations predict an increase in sputtering yield of up to 40%. It is also shown that closely spaced craters, due to elastic interaction with each other, compensate each other's elastic fields, which has an effect on the value of the sputtering coefficient.
