Published: October 2019

En este trabajo se analizan los procesos de deterioro que ejercen las comunidades de líquenes en las areniscas silíceas de dos monumentos del siglo XIX y XX de la ciudad de Guanajuato: escalinatas de la Universidad de Guanajuato y la Escuela de Música de la Universidad de Guanajuato. Además de contribuir al conocimiento del deterioro, se aportan datos sobre las especies liquénicas encontradas, las causas de su crecimiento y su papel en el desgaste del material pétreo, con la finalidad de implementar medidas de protección y prevención. Se observó la interfase liquen-roca usando técnicas complementarias como microscopía óptica, microscopía electrónica de barrido (MEB), microscopía electrónica de transmisión (MET), método analítico de plasma acoplado por inducción (ICP-MS, por sus siglas en inglés) y espectroscopía por energía dispersiva de rayos X (EDS, por sus siglas en inglés). Se identificaron cinco especies de líquenes: Xanthoparmelia mexicana, Xanthoparmelia tasmanica; Caloplaca aff. brouardii, Caloplaca aff. ludificans y Aspicilia sp. Dichos líquenes penetran de 0.5 µm a 50 µm en el substrato a través de sus rizinas, ocasionando la disgregación de minerales en la superficie rocosa (cuarzo, plagioclasa y feldespato). La disgregación de minerales junto con una disminución en la concentración de SiO2, Al2O3, Zn y K2O y un aumento en CaO, Fe2O3 y MgO demuestra un proceso de deterioro de los líquenes en los monumentos históricos de la ciudad de Guanajuato.

El significado que los adultos mayores otorgan a su dependencia funcional puede impedir el autocuidado para su salud y conducirlo a una dependencia total, situación que es posible evitar a través del desarrollo de intervenciones de enfermería enfocadas a la rehabilitación, educación y reconstrucción de su significado. Con el objetivo de comprender el significado que los adultos mayores otorgan a su propia dependencia funcional y describir los factores que explican la construcción del significado, se realizó un estudio cualitativo con cinco adultos mayores mexicanos que presentaban dependencia funcional según el índice de Barthel y autopercepción de dependencia. Los datos cualitativos se obtuvieron mediante una entrevista a profundidad semiestructurada, el muestreo fue por criterio lógico y el método de análisis se basó en la teoría fundamentada. Se encontró que el significado de dependencia funcional parte de la necesidad de recibir ayuda, la familia es la principal fuente de cuidado. Ser dependiente significa una transformación que involucra dejar de ser o hacer; incluye sufrimiento propio y de la familia y temor a lo desconocido. Los factores involucrados en la construcción del significado son: fuentes de ayuda, sentimientos y pérdidas físicas, sociales y económicas.

Published: October 2019

In this study, the changes in
the quality parameters of hazelnut beverages treated with low (LHT; 72°C for 20
min) and high temperature (HHT; 105°C for 1 min) after high pressure
homogenization process were determined during short (10 days) and long term (120
days) storage periods, respectively. Microbial viability was not detected in
any thermally treated samples. Although pH and titration acidity values of LHT
samples did not show important change during the storage, the pH values of HHT
samples decreased significantly. While protein solubility of LHT samples
increased during storage, it slightly decreased in HHT samples. Rheological
properties and also serume stability of LHT and HHT hazelnut samples changed
during storage. Hydroperoxide index value slightly increased in LHT samples
while it increased more than three times in HHT samples during storage. As a
result, the LHT and HHT hazelnut beverages had different structural and
physicochemical properties during storage.
The genetics and biomechanics of thoracic aortic diseases
Authors: Harky Amer , Fan Ka Siu , Fan Ka Hay
Published: October 2019

Thoracic aortic aneurysms and aortic dissections (TAAD) are highly fatal emergencies within cardiothoracic surgery. With increasing age, thoracic aneurysms become more prevalent and pose an even greater threat when they develop into aortic dissections. Both diseases are multifactorial and are influenced by a multitude of physiological and biomechanical processes. Structural stability of aorta can be disrupted by genes, such as those for extracellular matrix and contractile protein, as well as telomere dysfunction, which leads to senescence of smooth muscle and endothelial cells. Biomechanical changes such as increased luminal pressure imposed by hypertension are also very prevalent and lead to structural instability. Furthermore, ageing is associated with a pro-inflammatory state that exacerbates degeneration of vessel wall, facilitating the development of both aortic aneurysms and aortic dissection. This literature review provides an overview of the aetiology and pathophysiology of both thoracic aneurysms and aortic dissections. With an improved understanding, new therapeutic targets may eventually be identified to facilitate treatment and prevention of these diseases.

Authors: Zhdanova A.N. , Solotchina E.P. , Krivonogov S.K. , Solotchin P.A.
Published: October 2019

—We present results of research into the mineral composition of the Holocene sediments of Lake Malye Chany of the Chany lake system located in the Baraba steppe and comprising three lakes: Bol’shie Chany, Malye Chany, and Yarkul’, connected by channels. The sediments were studied by XRD, IR and Raman spectroscopy, laser granulometry, analysis of stable 18O and 13C isotopes, elemental analysis (XRF), etc. Mineral analysis has revealed predominant quartz, feldspars, and carbonates and subordinate gypsum, bassanite, pyrite, mica, chlorite, and kaolinite. Mathematical modeling of the XRD spectra of carbonates, using Pearson VII function, made it possible to identify the carbonate phases and determine their quantitative proportions. The obtained high-resolution carbonate record providing information about the stratigraphic distribution of carbonates in the dated section was compared with the available lithological, geochemical, and isotope data. Based on these data, we have reconstructed five stages of the Holocene evolution of the Malye Chany basin. It is shown that the proportions of minerals in the section vary in accordance with the lake level fluctuations in the alternating periods of the Holocene regional arid and humid climate. We compared the mineral compositions of the bottom sediments of Lake Malye Chany and Yarkovsky Pool of Lake Bol’shie Chany. The revealed mineral assemblages reflect the local specifics of the lake system and the influence of natural and climatic factors on the inland sedimentation processes.
Is R. Rorty’s Moral Philosophy Possible? Antifoundationalism and Kant’s Criticism
Authors: Alijauskaitė Agnė
Published: October 2019

This article aims to answer the main question raised – is Rorty’s moral philosophy possible? To what extent is it possible to treat it as an authentic theory? Rorty’s criticism of Kant and the Kantians, as one of the key points of contemporary moral philosophy, determines the posture in the moral domain and provides a certain place in discourse. The article states that, despite the fact that Rorty’s moral philosophy is not based on a particular theoretical concept, it can be considered as a fragmented whole consisting of several parts, one of which is the agent’s openness to the choice of moral identity. At the same time, we will critically question the position of Rorty himself – while maintaining the suspicion towards the sources of moral knowledge, he maintains an insufficient distance with one of his own sources of moral knowledge, namely historical progress.

A mechanism enhancing the radiation power of a gas-discharge lamp based on a mixture of neon, nitrogen, and a mercury dichloride vapor in the blue-green spectral interval as compared with that for a lamp based on a mixture of only neon and a mercury dichloride vapor has been determined. The optical characteristics and the plasma parameters, as well as the value of the reduced electric field, at which the specific discharge power introduced into the excitation of exciplex molecules of mercury monochloride is maximum, are found. The research results can be used to create a more efficient exciplex lamp that emits radiation bands in the blue-green spectral interval.
A Pool Model of the Mediator Exocytosis into the Synapse
Authors: Vasilev A. N. , Khvyl O. M.
Published: October 2019

A model describing the mediator release into a synaptic cleft and making allowance for the pool structure of the presynaptic region has been proposed. Namely, the presynaptic region is assumed to contain two pools with vesicles that accumulate the mediator. A nerve impulse stimulates the injection of mediator from the first pool into the synaptic cleft. Simultaneously, the mediator from the second pool diffuses into the first one. The replenishment of the second pool occurs by absorbing the mediator from the synaptic cleft. Various operational modes of this model are considered. In particular, specific features of the single-impulse transmission through the system are studied. The functioning of the system with a feedback (the output signal is supplied to the input of the system) is analyzed, and it is shown that, in this case, a parameter determining the feedback intensity has a critical character: at the parameter values not exceeding the critical value, the presence of feedback does not govern the functioning of the system at the qualitative level.

Published: October 2019

Amorphous, glass, and glass-ceramic materials practically always include a significant number (more than eight) of crystalline phases, with the contents of the latter ranging from a few wt.% to several hundredths or tenths of wt.%. The study of such materials using the method of X-ray phase analysis faces difficulties, when determining the phase structure. In this work, we will develop a method for the analysis of the diffraction patterns of such materials, when diffraction patterns include X-ray lines, whose intensities are at the noise level. The identification of lines is based on the search for correlations between the experimental and test lines and the verification of the coincidence making use of statistical methods (computer statistics). The method is tested on the specimens of a-quartz, which are often used as standard ones, and applied to analyze lava-like fuel-containing materials from the destroyed Chornobyl NPP Unit 4. It is shown that the developed technique allows X-ray lines to be identified, if the contents of separate phases is not less than 0.1 wt.%. The method also significantly enhances a capability to determine the phase contents quantitatively on the basis of lines with low intensities.

MODELING AND OPTIMIZATION OF MASHING PROCESS IN BEER PRODUCTION WITH RICE ADJUNCT
Authors: Mallawarachchi Samavath , Gunawardena Sanja
Published: October 2019

Adjuncts like rice, wheat and sorghum are used by beer manufacturers worldwide to reduce the cost of production by replacing malt as a starch source. Rice is the most widely used adjunct in Asian countries. Understanding the enzyme kinetics in mashing process is vitally important to maximize sugar yield at a minimum cost. In this research, a semi-empirical model was developed for the mashing process, based on enzyme kinetic equations and experimental results; and this model was used to optimize the operating conditions when enzymes are not added externally. As predicted by the model, when 30% (w/w) of rice was used as an adjunct the maximum sugar yield can be obtained at 56° C and 6.5 pH, and the optimum temperature for mashing process increases with acidity. Since the acidity of solution increases during the mashing process due to the formation of organic acids, use of an increasing temperature profile is recommended to get the maximum output from the mashing process.

Published: October 2019

Despite great achievements in oral health of populations globally, oral health problems remain in many communities all over the world, thus our study aimed to evaluate the antimicrobial activity of Monopterus albus skin mucus against selected oral pathogens. Monopterus albus is Asian swamp eel with elongated body like snakes. Their skin covered with thick layer of mucus. They are usually found as a sluggish in the stagnant waters as it has a weak swimming behavior. Although eels are capable of quick movements, but they tend to be lethargic and they rely on stealth swimming movements to capture their prey such as shrimp, frogs and other small fishes. With regard to this matter, aqueous and methanol extracts were prepared to test antimicrobial activities against selected oral pathogens; Gram-positive bacteria i.e. Enterococcus faecalis, Streptococcus pyogenes, Streptococcus mutans, Gram-negative bacteria which are Klebsiella pneumoniae, Pseudomona aeruginosa and fungus pathogens i.e. Candida albicans. The antimicrobial activities were determined by inhibition percentage. The results showed a dramatic decrease in the oral pathogens treated with eel skin mucus methanol extract higher than the aqueous extract. Enterococcus faecalis showed the highest activity while Candida albicans showed the lowest activity. After in-vitro evaluation for eel skin mucus activities, identification study using liquid chromatography-quadrupole-time-of-flight mass spectrometry (LC-QTOF-MS) was performed to investigate the compound responsible for the anti-oral pathogens activities, the results showed the presence of salvianolic acid G which strongly corelated with the antimicrobial activity against selected oral pathogens. Results were statistically significant with p < 0.001. In conclusion, the present study revealed that eel skin mucus can be considered as promising source for anti-oral pathogens activities.

The aim was the evaluation of meat performance in chickens Ross 308 after the addition of bee pollen and propolis in a combination with probiotic into diet for broiler chicken. A total of 180 Ross 308 broiler chickens of male and female sex were randomly divided into 3 groups (n=60): the control group (C) without additional supplementation, experimental group E1 supplemented with 400 mg bee pollen extract per 1 kg of feed mixture and 3.3 g probiotic (Lactobacillus fermentum) added to drinking water on a daily basis, and experimental group E2 supplemented with 400 mg propolis extract/1 kg feed mixture and 3.3 g probiotic (L. fermentum) added to drinking water on a daily basis. The feed mixtures were produced without any antibiotics and coccidiostatics. The fattening period lasted for 42 days. The findings of the work on the meat performance and carcass characteristics of chickens revealed that bee pollen in combination with probiotic was the most suitable feed supplement. Among the most noteworthy parameters affected positively (P≤0.05) by this supplement in comparison with control may be mentioned the breast part weight. Moreover, it seems likely that there was synergistic effect of bee pollen and probiotic manifested by higher live body and carcass weight (P≤0.05) in comparison with the control. Present results would also seem to suggest that propolis supplementation with probiotic had effects on meat performance and carcass characteristics of Ross 308 broiler chicken.

Allelopathic effect of water extracts of crushed sweet sorghum seeds of hybrids ‘Medovyi’ and ‘Dovista’ and variety ‘Sylosne 42’ and their effect on sugar beet (Beta vulgaris L.) seeds germination of hybrid ‘Ukrainian MS 97’ is presented. Water extracts of various concentrations (from 5 to 50 %) were prepared. The results were compared with the control treatment (distilled water). To estimate the growth rate of plants, the number of buds and leaves, plant height and the general condition of plants were examined. In regard to the chemical interaction of crops in mixed cropping, it was found that water extracts from sorghum seeds have a significant amount of allelopathically active substances revealing both phytotoxic and stimulating effects on the germination and germination vigour of sugar beet seeds. The water extracts of ‘Medovyi’ seeds showed the lowest allelopathic effect compared to other cultivars under study. Water extract of ‘Sylosne 42’ appeared relatively tolerant to germination of sugar beet seeds.
The extract of ‘Medovyi’ seeds was filtered and added into the agar medium on which the clones of Beta vulgaris L. were planted. Allelopathically active substances did not affect sugar beet plants on the 7th day after planting. A decrease in the number of buds, leaves and plant height was recorded on the 14th day. On the 21st day, sugar beet plants looked suppressed and eventually died off. Understanding of physical and biochemical mechanisms of plants interaction allows selecting physiologically compatible plants for high-productive phytocoenoses.

Microbial biofertilizers are considered environmentally safe tool for the healthy production of a plant. Massive application of synthetic pesticides and fertilizers in agriculture has resulted detrimental effect on nature and human health. In the current study, we isolated several strains of rhizoshpheric bacteria through screening from the diversed agricultural soil of Daegu, South Korea. The growth promoting ability of the isolated strains was checked on gibberellin-deficient rice dwarf mutant Waito-C, lettuce var. cheongchima and chinese cabbage var. wangmat. The strain having the higher ability to promote the Waito-c growth was selected and further investigation was done. The selected isolate was identified as Pseudomonas koreensis MU2 through 16s rDNA gene sequence analysis. The cultural filtrate analysis revealed that the isolate could produce endogenous phytohormone gibberellic acid (GA1 and GA3) and organic acids, such as citric acid, malic acid, and tartaric acid. Pot experiment revealed that the inoculation of Pseudomonas koreensis MU2 significantly increased shoot length, root length, fresh biomass, and dry biomass of chinese cabbage and lettuce. These results suggest that the Pseudomonas koreensis MU2 might be the possible candidate for bio-fertilizer as a plant growth-promoting rhizobacteria in plant.

For maintaining good health, one needs a proper balance and composition of intestinal microflora which can be achieved by supplementing probiotics. A noteworthy issue in creating helpful and valuable probiotic food items is bacterial survival, amid capacity and ingestion. Several gastrointestinal diseases can be reduced by colonizing Probiotic supplement as the appropriate barrier in the small intestine. Probiotic is characterized as a suitable microorganism with several medical advantages to the consumer when administrated in a satisfactory amount. The poor survival and steadiness of the probiotic microorganisms as revealed from the earlier reports is an essential question to that impact. Diverse natural components like oxygen toxicity, an intolerant condition of acidity and travel through the gastrointestinal tract offers a variety of extreme conditions to the probiotic microorganisms. Therefore, the current review is more emphasized upon the microencapsulation of the probiotics that enhance their viability against different parameters like oxidation, light, moisture, and temperature. Recent advancements in ensuring microorganism survival rate and their colonization in the gut as gut microflora using microencapsulation enhance probiotic supplements for better health. Hence, the present review also emphasis on the methodological systems used for probiotic alive by the encapsulation process advance technologies used to stabilize their viability during storage including the selection of biomaterial and decision for proper innovation.
Prescription Opioid Use in General and Pediatric Emergency Departments
Authors: Menchine Michael , Lam Chun Nok , Arora Sanjay
Published: October 2019

BACKGROUND AND OBJECTIVES:

Recent evidence reveals that exposure to emergency department (ED) opioids is associated with a higher risk of misuse. Pediatric EDs are generally thought to provide the highest-quality care for young persons, but most children are treated in general EDs. We sought to determine if ED opioid administration and prescribing vary between pediatric and general EDs.

METHODS:

We analyzed the National Hospital Ambulatory Medical Care Survey (2006–2015), a representative survey of ED visits, by using multivariate logistic regressions. Outcomes of interest were the proportion of patients ≤25 years of age who (1) were administered an opioid in the ED, (2) were given a prescription for an opioid, or (3) were given a prescription for a nonopioid analgesic. The key predictor variable was ED type. A secondary analysis was conducted on the subpopulation of patients with a diagnosis of fracture or dislocation.

RESULTS:

Of patients ≤25 years of age, 91.1% were treated in general EDs. The odds of being administered an opioid in the ED were similar in pediatric versus general EDs (adjusted odds ratio [OR] 0.88; 95% confidence interval [CI] 0.61–1.27; P = .49). Patients seen in pediatric EDs were less likely to receive an outpatient prescription for opioids (adjusted OR 0.38; 95% CI 0.27–0.52; P < .01) than similar patients in general EDs. This was true for the fracture subset as well (adjusted OR 0.27; 95% CI 0.13–0.54; P < .01).

CONCLUSIONS:

Although children, adolescents, and young adults had similar odds of being administered opioids while in the ED, they were much less likely to receive an opioid prescription from a pediatric ED compared with a general ED.

Los audífonos permiten escuchar detalladamente los sonidos captados o grabados gracias a su capacidad de aislar el oído de ruidos externos. Esto crea un entorno íntimo que facilita la inmersión de la escucha en la experiencia aural. Brindar audífonos inalámbricos a la audiencia de los espectáculos teatrales en Costa Rica podría aumentar la inteligibilidad de los diálogos actorales con el uso de micrófonos, reducir la intrusión de ruidos ajenos a la historia representada en la escena y resaltar, con detalle, los estímulos sonoros del espectáculo. En Costa Rica, no existen registros de espectáculos que hayan utilizado audífonos para entregar su sonido a la audiencia, por lo que resulta difícil valorar su impacto estético. Ante la falta de un referente técnico para lograr un sistema de sonido basado en audífonos, este documento propone un diseño técnico de un sistema que realiza la transmisión de la señal de forma inalámbrica.

Authors: Soto Monge Ivannia Sofía
Published: October 2019

La presente investigación muestra los resultados obtenidos del estudio y análisis del modelo pedagógico de la carrera de Historia del Arte en la Universidad de Costa Rica desde el año 1970 hasta el 2017. Su abordaje metodológico parte de la construcción de un estudio de caso, a través de la utilización de categorías y subcategorías de análisis, desarrolladas a partir del estudio teórico-conceptual sobre el modelo pedagógico, así como la información curricular encontrada en los planes de estudio de la carrera. A partir de los resultados obtenidos, se concluye que existe una ausencia de fundamentos teóricos propios de la educación que sustenten la existencia de un modelo pedagógico en la carrera

Sistem pangan global semakin dituntut untuk memenuhi permintaan ikan seiring meningkatnya tingkat konsumsi ikan di masa depan. Tujuan penulisan makalah ini adalah untuk memberikan gambaran bahwa CBF sebagai solusi cepat dalam meningkatkan produksi ikan termasuk mengoptimalkan produktivitas di suatu perairan sehingga mempersempit kesenjangan antara permintaan akan sumber protein hewani dan pasokan sumberdaya ikan melalui peningkatan produksi. Melalui analisis deskriptif terhadap data statistik perikanan nasional tahun 2002-2017, kajian pustaka terkait dengan CBF dan hasil tangkapan yang didaratkan di Waduk Malahayu tahun 2008-2016, diperoleh gambaran bahwa upaya meningkatkan produksi ikan melalui CBF di Indonesia dengan mengikuti kaidah ilmiah merupakan opsi yang tepat untuk meningkatkan produksi perikanan tangkap. Penerapan CBF memerlukan penguatan kelembagaan, petunjuk teknis yang jelas dan tersosialisasi dengan baik serta penguatan peran lembaga penyedia benih. The global food system is increasingly being demanded to meet demand as the level of fish consumption increases in the future. The purpose of this paper is to provide an overview of CBF as a solution in narrowing the gap between the demand for sources of animal protein and the supply of fish resources through increased the production include maximizing the productivity. Through descriptive analysis of the national fisheries statistical data for 2002-2017, literature review related to CBF and catches landed in Malahayu reservoir in 2008-2016, an illustration is that efforts to increase fish production through CBF in Indonesia by following scientific rules are the right option to increase capture fisheries production respectively. Implementation of CBF requires institutional strengthening, clear technical guidance and well-socialized and strengthening the role of seed provider institutions.

Mangrove forests are tropical coastal vegetation communities, which has the ability to grow in coastal area with tidal and muddy environment. Several functions of mangrove forest such as ecological functions can be used for coastal protection, trapping sediment and strengthen the coastal ecosystems. Coastal waters in Dompu Regency, West Nusa Tenggara have natural mangrove ecosystem with a huge potency and advantages to the region. This study aimed to understand the condition of mangrove ecosystem based on satellite image analysis of Landsat 8 Operational Land Imager (OLI) in 2014 and assess the potency, information related to the utilization by community. Data collection in this study were combined from satellite imagery interpretation with interview and questionnaires. The results showed that the mangrove forest extent in Dompu Regency Coastal Waters were about 90,631 ha with uniformity index 0.68 (medium uniformity). Two mangrove species were found in the region namely Rhizopora stylosa and Rhizopora apiculata and used by the community for several purposes such as firewood, natural coastal protection from tidal, waves and abrasion, also for crabs and fish spawning ground.
The Universalism of Political System Principles Espoused by European States
Authors: Zieliński Eugeniusz
Published: October 2019

A distinctive trend developed in 19th and 20th century Europe, which saw the universalisation of principles of state political systems. This tendency expressed itself in proclaiming in the constitutions of individual states and in the practical application by European democracies of the political principles inspired by the ideas of the Enlightenment. Over a period of over two centuries, the constitutions of many countries developed with a similar catalogue of principles of government, in a similar legal form. These principles express the same ideas and political values and aim at developing an identical model of government structure based on liberal-democratic ideals. It is characteristic that during the last decade of the 20th century there was a sudden increase in this tendency and the spreading of those principles to over twenty countries.
The Unethical (Subliminal) Advertising
Authors: Nierenberg Bogusław
Published: October 2019

The unethical advertising does not necessarily have to be forbidden. Sometimes a thing arousing common objection is not prohibited. The thing forbidden may only be something synonymously codified. The unethical advertisement which affects ones subconsciousness, constitutes an interesting instance. It was and has been of interest not only of scientists but also various impostors. Zigmund Freud was the one who proved that subconsciousness plays an enormous role in human’s life and may govern one’s acting without the consciousness taking part. There is nothing more tempting for advertising specialists, then and as a result, majority of countries forbids this kind of activity. In Poland as well, in “The Law Concerning Combating the Unfair Competition” (1993), such practices were prohibited. In the art. 3, law 1 it is said that by the unfair competition we understand acting against the law or against good custom if it establishes a threat or violates other contractor’s or client’s business. In the art. 16, law 1, point 4, one may read that such a deed in the advertising domain stands for the utterance, which by encouraging to purchase or to make use of particular service makes an impression of a neutral information. In particular, we mean here the so-called hidden advertisement or cryptoadvertisement. For many years the Polish legislator had not perceived it as necessary to refer to the subconscious or unethical (subliminal) advertisement.
Kontynuuj czytanie A Role of Political Face in The Process of Creating a Political Image
Authors: Wnorowska Małgorzata
Published: October 2019

Adopting a new face – a mask – might be one of the conditions for a comeback to the political scene. A political face is not a synonym for identity because it is not shaped by the public, but it consists a sort of mask which is put on a politician by his/her image advisors and next presented to the public. This paper attempts to verify a thesis that a political face is not a synonym but an unstable element of a political image. The political image again is an equivalent for socio-political identity. Most definitions which appear in works on political communication treat the political image as a kind of Ego reflected in a way similar to the concept of Marzena Cichosz, who indicates, that the image consists of a set of features, which in the opinion of the public the subject possesses.
Sacralisation and Purification of the Nation in the Polish and Russian Nationalist Thought?
Authors: Bäcker Roman
Published: October 2019

Both in the Polish and Russian language the term ‘nation’ is understood in a slightly different way than the English word ‘nation’. It is understood not only in cultural but also political terms, and in numerous contexts it is used to denote ‘the people’ or an ‘ethnic nation/ethnos’. Thus, when we use words ‘nation, nationality, narodnost’, sometimes only the context makes it possible to decide whether we mean the nation, nation or ethnos. However, this lack of clear distinction in the colloquial discourse should not make one conclude that there are not fully shaped nations in Poland and Russia. It is just that the colloquial discourse fails to notice these vague distinctions. In the scientific discourse in both countries, these di! erentiations have been precisely defined and used for a long time.
