Advances in Carbon Fiber Reinforced Polyamide-Based Composite Materials
Authors: Kausar A.
Published: January 2020

Carbon fiber has been used to reinforce both aliphatic and aromatic polyamides. Aliphatic polyamide is known as nylon and aromatic polyamide is often referred to as aramid. Among aliphatic polyamides, polyamide 6, polyamide 6,6, polyamide 11, polyamide 12, and polyamide 1010 have been used as matrices for carbon fiber. Factors affecting the properties of polyamide/carbon fiber composites are: fiber amount, fiber length, fiber orientation, matrix viscosity, matrix-fiber interactions, matrix-fiber adhesion, and conditions encountered during manufacturing processes. This article presents a state-of-the-art review on polyamide/carbon fiber composites. Polyamide/carbon fiber composites are lightweight and exhibit high strength, modulus, fatigue resistance, wear resistance, corrosion resistance, gear, electrical conductivity, thermal conductivity, chemical inertness, and thermal stability. Incorporation of oxidized or modified carbon fiber and nanoparticle modified carbon fiber into polyamide matrices have been found to further enhance their physical properties. Applications of polyamide/carbon fiber composites in aerospace, automobile, construction, and other industries have been stated in this review. To fully exploit potential of polyamide/carbon fiber composites, concentrated future attempts are needed in this field.
In Vitro Pro-Glycative Effects of Resveratrol and Caffeic Acid
Authors: Kurin E. , Mučaji P. , Nagy M.
Published: January 2020

Resveratrol and caffeic acid belong to plant polyphenols and are known for their antioxidant effects. The aim of our research was to study their impact on Maillard reaction. This one occurs when the reducing saccharides react with amino groups of biomolecules including proteins, alter their protein conformation and transform to the variety of advanced glycation end products (AGEs). AGEs exhibit browning and generate fluorescence. There exist expectations that this oxidative protein glycosylation could be prevented by antioxidants. In this study, we incubated bovine serum albumin (BSA) with glucose for 7 days at 37°C and measured characteristic fluorescence and UV absorbance of the formed AGEs. Surprisingly, resveratrol and caffeic acid enhanced transformation of BSA to glycation products, which was confirmed either when cupric Cu(II) or ferric Fe(III) ions in nanomolar concentration were added to the system as pro-oxidant agent.
On J-colorability of certain derived graph classes
Authors: Fornasiero Federico , Naduvath Sudev
Published: January 2020

A vertex v of a given graph G is said to be in a rainbow neighbourhood of G, with respect to a proper coloring C of G, if the closed neighbourhood N[v] of the vertex v consists of at least one vertex from every color class of G with respect to C. A maximal proper coloring of a graph G is a J-coloring of G such that every vertex of G belongs to a rainbow neighbourhood of G. In this paper, we study certain parameters related to J-coloring of certain Mycielski-type graphs.
Development of Mask Design Knowledge Base Based on Sensory Evaluation and Fuzzy Logic
Authors: Hong Yan , Xue Zhebin , Liu Chunyu , Dai Xiaoqun
Published: January 2020

This article focuses on the development of the mask design knowledge base, which is expected to be applied in a personalized mask design system. To realize the proposed knowledge base, a perceptual descriptive space of the mask is first developed for the description of both functional and aesthetic perceptions of a mask. The mask ontology is also developed to form the mask element matrix. Mask design knowledge is expressed as the relationship between the perceptual descriptive space and the mask ontology, which is extracted by a group of experienced designers through a sensory evaluation procedure. This relationship is then simulated by fuzzy logic tools. The proposed knowledge base has been validated that it is reliable. The personalized mask design system can be further developed with the propose mask design knowledge base.

Authors: Benazouzi Y. , Rozale H. , Boukli Hacene M. A. , Khethir M. , Chahed A. , Lucache D.
Published: January 2020

In this paper, we performed a first principle study for new half-Heusler LiSrX(X= N, P, and As) working with WIEN2k code in the frame work of the density functional theory, and the Boltzmann theory. We estimated the exchange-correlation potential by the generalized gradient approximation (GGA). Energetically, the three compounds show a high stability in structure type2, we notice that the lattice constant increased while bulk modulus decreased in replacing the ions of size increasing. Based on our calculations, LiSrN, LiSrP, and LiSrAs compounds are mechanically stable, and show semiconductor nature with indirect band gaps of 1.21, 1.75 for LiSrN and LiSrAs, and direct band gap of 1.94 eV for LiSrP. The thermoelectric properties are calculated for LiSrX (X=N, P, and As) and they found a high power factor for the p-type doping concentration.
Assessing the role of soil microbial communities of natural forest ecosystem
Authors: Matei Gabi-Mirela , Matei Sorin , Mocanu Victoria
Published: January 2020

In forests, edaphic microbial communities are involved in litter decomposition and soil forming processes, with major contribution to humification, especially bacteria and fungi being responsible for the main ecosystem services fulfilled by the soil. Research has been carried out aiming to characterize the structure and diversity of microbial communities in the Rendzic Leptosols (WRB) under natural deciduous forest from Visterna, Babadag Plateau and to assess their contribution to ecosystem services provided by soil. The paper presents the results of quantitative estimations and taxonomic composition of soil and litter communities of heterotrophic bacteria and fungi, identification of cellulolytic species, as well as the microbial biomass and global physiological activities expressed as soil respiration potential. More than a half of bacterial species were common in litter and soil (SI=57.14%) and were represented by dominant species of fluorescent or non-fluorescent pseudomonads andBacillus subtilisbut no similarity was found between the two fungal communities. Fungal populations included cosmopolitan species, such as antagonists and strong cellulolytic representatives of generaPenicillium,Trichoderma, Mortierella, Chaetomium, Epicoccum, Aspergillus. Microbial density and microbial biomass presented the highest values in the litter (684 mg C x kg-1d.s.) and in surface horizon Am1 of soil profile than in the bottom layers. The highest diversity was found in Am1 horizon (0-5 cm) H’=1.983 bits and ε=0.869 for cellulolytic community. Soil respiration reflected the intense physiological activity of microbiome, with high values associated to numerous effectives of bacteria and fungi especially in surface horizon. Microorganisms identified contribute to formation of soil by recycling of nutrients, cellulose decomposition, the synthesis of stable organic matter (humic acids), aggregation of soil particles, biological control of pathogens by antagonistic activity. They improve plant uptake of water and nutrients by forming symbioses (ectomycorrhizae), thus modelling the structure of vegetation.

Published: January 2020

Yarrow essential oil is used in complementary and alternative therapy for several diseases. Biological effects of essential oils span various cells and microorganisms. The aim of this study was to investigate the effects of different concentrations of the essential oil obtained from the yarrow plant (Achillea millefolium) on HeLa (CCL-2) cells. The components of the essential oil were studied by means of GC-MS analysis. Out of 10 determined compounds in the essential oil; 1,8-Cineole, Camphor, Beta-eudesmol and Camphene were found to be higher than others; and their biological effects were depicted with Ingeniuty Pathway Analysis (IPA) analysis. Moreover, cell cycle and proliferation tests were conducted on HeLa cells where yarrow plant’s essential oil was used. When extracted yarrow oil applied on HeLA Cells, apoptotic effects had been determined, furthermore proliferation of these cells decreased. In addition, activation of cell cycle control points was observed . Essential oil components could arrest the development of HeLa cells due to induction of cellular damage control mechanisms. In conclusion, we propose that the essential oil had a more repressive effect on HeLa cells, decreases their proliferation and prevented the increase in the number of cells.
The role of C-terminal amidation in the mechanism of action of the antimicrobial peptide aurein 1.2
Authors: Shahmiri Mahdi , Mechler Adam
Published: January 2020

C-terminal amidation is a common feature of wild type membrane disrupting antimicrobial peptides (AMPs). Empirical evidence suggests that this modification increases antimicrobial efficacy. However, the actual role of C-terminal amidation in the molecular mechanism of action of AMPs is not fully understood. Amidation alters two key properties simultaneously: the net charge and helicity of the peptide, both of which are implicated in the mechanism of action. However, the differences between the physicochemical properties of the carboxyl and amide moieties have been disregarded in former studies. In this study we assessed whether the difference in activity is only caused by changes in the helicity and overall charge of a peptide, i.e. whether the chemistry of the terminus is otherwise irrelevant. To do so, the membrane disrupting activity of a modified aurein 1.2 peptide was studied in which a secondary amide was formed with a terminal methyl group, instead of the primary amide as in the wild type peptide. Results of quartz crystal microbalance, dye leakage and circular dichroism experiments show that the activity of the modified peptide is substantially reduced compared to the wild type peptide, in particular that the modified peptide exhibited a much-reduced ability to bind to the membrane. Thus, the primary amide at the C-terminus is required to bind to the membrane, and a secondary amide cannot serve the same purpose. We hypothesize that this difference is related to the hydration state of the terminus. The lack of membrane binding ability of the modified peptide identifies the primary amide moiety at the C terminus as a specific membrane binding motif.
Effects of zinc and molybdenum on European Bluestar (Amsonia orientalis): An in vitro study
Authors: Acemi Arda , Duman Yonca Avcı , Karakuş Yonca Yüzügüllü , Özen Fazıl
Published: January 2020

This study aimed to investigate the effects of possible zinc (Zn) and molybdenum (Mo) contaminations on the critically endangered European Bluestar (Amsonia orientalis). The effects of Zn and Mo were tested in a dose-dependent manner on in vitro cultures. Zn at 0.1 mM in the medium inhibited root development whereas Mo showed the same effect only at ≥2.5 mM concentration. Gradual inhibition of shoot development was observed after treatment with both metals. Protein contents were also negatively affected by increasing metal concentrations, while proline levels increased gradually. Successive increases in metal concentrations resulted in higher hydrogen peroxide (H2O2) and malondialdehyde (MDA) concentrations. The activity of the antioxidant enzymes, peroxidase (POD) and catalase (CAT), were found to be enhanced in response to increasing metal concentrations. Superoxide dismutase (SOD) activity decreased after Zn treatment but increased after Mo treatment. A marked increase in POD and CAT in response to metal stress suggests that these enzymes might have a significant cooperative role in regulating H2O2 production, although CAT, in response to drought and salt stress, has been reported to only play a supplementary role in A. orientalis. These results indicated that A. orientalis is susceptible to long-term Zn stress but can tolerate up to 2.5 mM Mo in the long-term. Deficiency of Mo is more common than high toxic concentrations in the environment. Therefore Zn contamination should be considered as one of the major threats for A. orientalis in its native habitat.
Compared salt tolerance of five local wheat (Triticum aestivum L.) cultivars of Albania based on morphology, pigment synthesis and glutathione content
Authors: Bacu Ariola , Ibro Vjollca , Nushi Magdalena
Published: January 2020

Stressful saline concentrations in soils affect photosynthesis by damaging pigments, photosystems, components of electron transport system, and enzymes involved in the process. Plants respond through very complex stress adaptation mechanisms including proteome modulation, alterations in pigment content, cell osmotic adjustment and control of ion and water homeostasis mechanisms, which stabilize cytosolic glutathione redox potential, etc. The level of plant sensitivity depends on salt toxicity levels, growth stage, physiological and genetic factors. With aim the investigation of the salinity tolerant cultivars, and for the elucidation of mechanisms underlying this complex biological process, here we analyze the impact of four NaCl concentrations (0-50-100-200mM) in growth parameters (root, shoot and leaves length), pigment content (chla, chlb, carotenoids), and GSH content, during seedling of five bread wheat (Triticum aestivum L.) cultivars in modified Hoagland solutions. Based on biometric parameters, pigment synthesis and GSH content cultivar Nogal is salt-sensitive (growth and pigments reduced); cultivar Viktoria is medium-tolerant (growth partially impaired, pigments constant), cultivar Toborzo and cultivar Suba are medium-tolerant (growth partially impaired, pigments increased), cultivar Dajti salt-tolerant (growth partially impaired/ leaves developed, pigments increased). Quantity of GSH in response to different levels of salinity is cultivar specific, and time of exposure to salinity is in negative correlation to GSH content for all investigated cultivars.

Digital Village Transformation: A Model for Relativizing Regional Disparities in the Republic of Serbia
Authors: Manasijević Aleksandar , Milojković Marko , Mastilo Dejan
Published: January 2020

The regional reality of the Republic of Serbia is characterized by strong regional disparities and adverse demographic trends. This situation is the result not only of inadequate actions of makers of macroeconomic policy and implementation of inefficient models of regional development in modern conditions, but of a long-term process of inheritance and deepening of regional disparities. The consequences of uneven regional development are numerous, and despite the economic ones, it is very important to emphasize the importance of non-economic consequences of uneven regional development. This primarily refers to the unfavorable demographic flows caused by the bipolarization of the state to the developed north and undeveloped south. Migratory trends in the Republic of Serbia can be observed in three different, however, interrelated processes. The first relates to migration from villages to cities, the second to migration from south to north and the third to migration directed beyond the borders of our country. These processes led to the extinction of the Serbian village and to the demographic emptying of the periphery of the Republic of Serbia. This is best supported by the fact that every fourth village is in the process of demographic disappearance, while every fourth agricultural resident of the Republic of Serbia is at risk of poverty. However, in the Zajecar district, the municipality of Sokobanja, one can notice the digital transformation of Vrmdža village, similar to the digital transformation of villages in developed countries. This transformation has attracted a large number of young families from this village doing business activities through the internet and modern digital technologies. The aim of this paper is to investigate the digital transformation of the village of Vrmdža by presenting a specific model of village transformation that can significantly contribute to the relativization of regional disparities in the Republic of Serbia.
Can Sleep Duration Help Explain Differences in the Happiness Index Across Nations?
Authors: Kamal Azza Mohamed
Published: January 2020

Inadequate sleep is an important public health problem that can affect one in every three adults; however, it received little attention in the economics of happiness research. The objective of this article is to examine whether sleep adequacy contributes to the explanation of variation in happiness index levels across countries. Analysis was undertaken using ordinary least squares regression method. The dependent variable is the self-reported happiness index developed by the Gallup poll and published in the World Happiness Report. Two alternative model specifications were used. The first included average sleep minutes per country, GDP per capita(purchasing power parity), unemployment rate, and environmental performance index. The second model specification included average sleep minutes per country, GDP (purchasing power parity), and economic freedom index. Both model specifications met several robustness checks, and showed overall significance and significant coefficients. Results showed that an increase in average sleep duration by 10 minutes is associated with an improvement in the happiness score by 0.1 and 0.15 points in the first and second model specifications respectively, noting an average happiness score of 6.2 in the country sample. The conclusion that sleep duration contributes to explaining variation in happiness levels across countries is a call for policy makers to consider policies targeting improvement in sleep adequacy as priority, and to direct more resources to further research in the area of sleep economics. Previous studies in the area of happiness economics did not consider sleep in explaining differences in happiness among countries, and previous studies in the area of economics of sleep did not consider the happiness index at a global level.

Developing a Tool for Quality and Accreditation of a New Generation University in the Digitalized Society: The Case of a Thematic-Technical University
Authors: Toprak Metin , Bayraktar Yüksel , Erdoğan Armağan , Kolat Deniz , Şengül Mehmet
Published: January 2020

In Turkey, digitalization of curricula, teachers, course materials, and educational technologies is relatively slower when compared with the ones in economic sectors and state services in general. In this study, we proposed a model for a new generation university in a digitalized society. The Council of Higher Education classifies universities in three categories (mission) to respond to technological and economic developments in the societal life: research, regional-development oriented and thematic universities. At national level, a digital transformation office acts as a coordination and orchestration body among governmental institutions in order to carry and transform public services into digital environment. The private sector naturally has to be digitalized by national and international severe competition.

The tool developed in this study based on the model developed by Toprak et al. (2019). That model aims to compensate for coordination gaps in the traditional university hierarchical structure, which is designed as department, faculty board, university board and senate, from administration to governance. Five innovations can be mentioned in terms of organizational and functional configuration of a university model proposed there: (i) profile of graduate and mission of the new generation university in the fields of education, research and community services, (ii) policy development and implementation offices, (iii) university ecosystem consultation and steering committee and other committees and boards, (iv) concept courses and branded courses, (v) coop education and solution partnerships. The Rector’s Office acts as an executive committee to prevent coordination gap in the proposed model.

A checklist has been developed for the processing of that model and hence it is made possible to measure the performance of an applied university and degree of compatibility with the model. Thus, the framework and content of the mechanism and tools traditionally used in quality assurance and accreditation will need to be updated in line with this model.
Business-Government Interaction: A Thematic Analysis
Authors: Roy Oleg
Published: January 2020

The article analyzes the interaction between business and government, the purpose of which is to identify the leading thematic blocks, where the most significant issues underlying this interaction are concentrated. Highlighting two meanings in the practice of interaction between business and the state, in one of which the state merges with business, and in the other - disagrees with it on key issues, the author proposes to use the theory of stakeholders of I. M. Jawahar and G. L. McLaughlin. The use of this theory allows to identify several types of interaction, including six main functions: facilitating, stimulating, control, sanctions, arbitration and regulatory. The content of these functions is concentrated in the list of basic activities of authorities in the field of regulation of business processes. For the purpose of complex and systematic consideration of these functions, the article proposes a 3D model of interaction between government and business. On the basis of this model the author carries out the content analysis of materials of the leading among businessmen of the Omsk region newspaper “Commercial news” on the basis of which the leading thematic blocks of interaction of the power and business updated by various types of lighting are allocated (analytical article, interview, reportage, a note). The important role of the media in assessing and structuring the relationship between public authorities and business structures determines the usefulness content analysis and the choice of the object of the study. The study highlighted a number of leading thematic blocks of interaction, updated on the pages of the weekly in the period from 2018 to mid-2019. Based on the study, the author identified and ranked thematic blocks considered in the context of his proposed 3D- model, formulated the most characteristic problems of interaction between business and government at the present stage.
Effects of Digital Transformation and Network Externalities in the Telecommunication Markets
Authors: Radukić Snežana , Mastilo Zoran , Kostić Zorana
Published: January 2020

The main purpose of the paper is to address the effects of digital transformation in the telecommunications markets which are characterized by network externalities. By acknowledging disruptive effects of digital transformation age, the paper highlights challenges which were created by advancement of technological capabilities. The specific aim of the paper is to present a methodological framework for measuring the information society. The research will be based on an analysis of the number of subscribers by types of telecommunication services, in developed and developing countries, in the last two decades. In this regard, increasing the number of subscribers leads to higher value of the selected network. We expect confirmation of both hypotheses respectively (H1: Digital transformation affects the simultaneously continuous growth of the number of subscribers and the continuous decline in prices of telecommunication services; H2: There are similar trends in developed and developing countries, which are related to the number of the telecommunication services subscribers). Therefore, digital transformation and the effect of network externalities contribute to increasing the number of subscribers, reducing the number of networks (distortion of the market competition) and reducing the prices of telecommunication services.
The Eu Enlargement. How to be Like the Irish and not the Greek?
Authors: Mahmutefendic Tahir
Published: January 2020

Apart from the former EFTA members (Iceland, Lichtenstein, Norway and Switzerland) and a few former republics of the Soviet Union (Bjelorussia, Moldova and Ukraina) the countries of the Western Balkans are the only European states outside of the European Union. They are very keen to join the Union. The Balkans have always been the poorest part of Europe. The appeal of the wealthy European Union is apparent. Access to the largest market in the world, investment, modern technologies and generous regional funds give a hope that by joining the EU the Western Balkans countries will join the rich club. At the moment performance of the Western Balkan countries does not guarantee that they will become rich by joining the European Union. Their current production and trade structure makes it likely that the Western Balkan countries will be locked in inter-industry trade in which they will export products of low and medium technological and developmental level and import products of high technological and developmental level. This might lead to divergence rather than convergence between them and the European Union. In other to overcome this problem the Western Balkan countries need to conduct radical reforms in the public sector, fiscal policy, industrial trade and investment policy. They also need to tackle corruption, simplify administrative procedure, strenghten property rights and the lawful state. All this with the aim to change economic structure and shift from achievements of the second and third to fourth technological revolution. Only if these reforms are successfuly implemented the Western Balkan countries can hope to avoid the Greek scenario and possibly experience the Irish scenario.

Published: January 2020

This paper presents the application of the multiple regression analysis model in macroeconomic research using the model of Bosnia and Herzegovina in the period from 2005 to 2018. The objective of the research is to evaluate the effects of macroeconomic factors (independent variables) to gross domestic product (dependent variable), and based on theoretical and methodological research. Applying the Enter method, out of six independent variables, they are all included in the regression model, whereas the sequence of inclusion in the model is the following: foreign direct investments, Import, Export, Growth rate, unemployment and inflation. Numerous research indicate positive connection between gross domestic product as the dependent variable and foreign direct investments, Import, Export, Growth rate, unemployment and inflation, as independent variables. Other factors negligibly explain the most important indicator of economic activities of a country. Our assignment is to either confirm or reject the abovementioned statement.

Published: January 2020

Digital technology technologies and business practices are expected to radically transform the competitive landscape and society. Central to changing business practices is how digital technologies are transforming the practice of marketing which in turn is transforming the nature of markets globally. This paper, guided by the literature concerning the wave of digital disruption brought about by new technology, changes in consumer demand and new forms of business competition discusses industry level and macroeconomic impact of the digital transformation of marketing. The drivers of the digital transformation in marketing, the critical role of understanding the consumer value chain relative to marketing practice and the impact of changing business practices on the larger economy. A new model developed by (Teixeira, 2019) to assess consumer demand is described as a marketing practice innovation that can be used to gain new insights for innovation and marketing. These innovations in gaining market insights and in marketing strategies are discussed regarding implications for industry and macroeconomic policy. The authors call for calls for further research using this methodology to better understand how digital disruption is likely to impact firm competitiveness and the nature of larger global economy.
Application of the T-Test in Health Insurance Cost Analysis: Large Data Sets
Authors: Kresojević Bojan , Gajić Milica
Published: January 2020

In this paper will be analyzed the application of the t-test against the nonparametric Mann - Whitney test in the analysis of health insurance benefit costs in the Republic of Srpska on large samples. This research aims to examine which method produces better results when testing statistical hypotheses. The adequacy of the statistical tests will be tested on primary health insurance cost data for 1,044,690 insureds in 2017. For two samples of size 4,000, the sampling distribution of the difference in two means has a skewness coefficient of 0.05 and a kurtosis coefficient of 3.09. Jarque - Bera test does not reject the hypothesis of normality of distribution with a p-value of 0.135. On the other hand, in the Mann - Whitney test, the real risk of the first species, when there is a difference in skewness between the samples, may be less than 0.001 compared to the nominal risk level of 0.05. Based on the results obtained, it is suggested to use the t-test instead of the Mann - Whitney test if the sample is large enough, which should be verified by the bootstrap method.
Om Postkolonialisme, Migrasjonsprosesser Og Hybride Identiteter. En Lesning Av Eva Scheers Vi Bygger I Sand (1948)
Authors: Brovold Madelen Marie
Published: January 2020

This article examines what one might call migration literary features in the Jewish Norwegian author Eva Scheer’s novel Vi bygger i sand (1948). I will investigate themes and sections that in different ways emphasize the migration experience of the characters within the novel. The focal point of the analysis is the migration experience in itself, what it means to be forced to move from one country to another and having to learn how to live in a different country and community, perceived identity and identity issues, prejudices, anti-Semitism and the fear of persecution. Because of this chosen focal point, I will use postcolonial theory in my reading of the novel, emphasizing Homi K. Bhabha’s concepts of mimicry and hybridity. What does it mean to belong to a nation? Is it possible to become Norwegian while keeping parts of your homeland’s identity? With the altered migration pattern of recent decades, such issues make the novel relevant even today.
Der Fremde Im Königreich Der Dänen. Das Wort, Der Diskurs Und Die Fremdheit in Bronisław Świderskis Roman Słowa Obcego
Authors: de Bończa Bukowski Piotr
Published: January 2020

The prose work of the Polish exile writer Bronisław Świderski, who has been living in Denmark since 1970, explores strangeness – an important topic of modern literature. Świderski addresses strangeness not only as an individual experience, but also as a social problem. In this article, I would like to take a closer look at the analysis of foreignness and the psyche of an immigrant in Świderski’s award-winning novel Słowa obcego (1998). From many problems addressed in the novel, which are directly or indirectly connected with strangeness, I want to take out one aspect. At this point I will be interested in the relationship between language (discourse) and strangeness.
Mellem Det (Post)Koloniale, Det (Post)Nationale Og Det Globale: En Analyse Af Niviaq Korneliussens Homo Sapienne
Authors: Lubowicka Agata
Published: January 2020

The paper presents a close-reading of the Greenlandic author Niviaq Korneliussen’s novel Homo sapienne (2014) with the aim of answering the question, whether it can be defined as a postnational or a migration novel, according to the definitions presented by Elisabeth Oxfeldt and Søren Frank. To this end four different categories: the hybrid, the (post)colonial, the national and the global are applied in the analysis with the primary focus on examining how the dominating narratives of Greenlandicness are confirmed, challenged or rejected in the novel, as well as how the novel’s language, structure and narrative strategies not only contribute to a new understanding of the genre, but of the issues in question in general.
Zwischen Räumen. (Un-)Möglichkeiten Von Fremdheit in Henri Nathansens Roman Af Hugo Davids Liv
Authors: Räthel Clemens
Published: January 2020

Henri Nathansen’s highly successful bildungsroman Af Hugo Davids Liv, first published in 1917, tells the story of its Jewish protagonist from cradle to grave – with obstacles, adventures and challenges. But much more so, Nathansen offers a multi-layered narration of what it could mean to be a “noble” Jew. Providing a multitude of answers to that question, Af Hugo Davids Liv refuses any definition and thus opens a “third space” in which ambiguous and grained narrations of migration can take place, flourish and be understood in their own right. The article focuses on exploring these narrative interstices and spaces of in-betweenness and in doing so also (re-)discovers Nathansen’s unique way of telling migration as socially always imminent.
I Guds Namn. Migration Och Främlingskap I Lennart Hagerfors Längta Hem. Om Ett Missionärsbarn I Kongo
Authors: Rinderle Hanna
Published: January 2020

In this article I analyze the autobiographical novel Längta hem. Om ett missionärsbarn i Kongo (2003) by Lennart Hagerfors in order to understand how otherness is presented and how it is linked to the status of migration and being Swedish. I argue that the novel shows two distinct forms of otherness. The first is on the personal and individual level of the protagonist that is caused by his migration from Sweden to Congo. The other is on a cultural and national level, which situates Sweden in between the Congolese and French culture. While the first personal form of strangeness is viewed as problematic and must be overcome, the second form can be read as an expression of the positive Swedish self-image that situates Sweden outside of Europe’s colonial history and therefore posits Sweden as a type of humanitarian Great Power or global conscience.
Å Reise Nordover Eller Å Utfordre Det Norske: Ailo Gaups Trommereisen Og Helene Uris Rydde Ut
Authors: Sibińska Maria
Published: January 2020

The article elucidates the presence of the Sami undercurrent in Norwegian literature. Proceeding from Elisabeth Oxfeldt’s theoretical work on the post-national and on the Bhabhanian concept third space, two novels are being discussed: Ailo Gaup’s Trommereisen (1988) and Helene Uri’s Rydde ut (2013). Gaup’s works constitute the first samic voice in Norwegian literature, which explicitly verbalizes the despair emanating from the loss of continuity as regards to the self-image and the self-identity of many samic individuals. Uri’s auto-fictional text combines family research with editing and correcting the nation’s biography. Emphasizing the novels employment of the travel north as a driving force behind the plot and as a metaphorical device, the author of the article interprets the novels as an expression of hope to transgress the social reality and re-establish the lost coherence of personal and national history either by means of shamanic knowledge and practice (Trommereisen) or by means of discursive practice (Rydde ut) that liberates the individual from rigid preconceptions regarding identity and cultural belonging.
Musik I Migrationslitteratur Analyse Af Eksplicitte Referencer Til Musik I Alen Meškovićs Romaner
Authors: Slouková Radka
Published: January 2020

This article analyses explicit references to music in the novels of the Danish-Bosnian writer Alen MeškovićUkulele-jam(2011) andEnmandstelt(2016). Mešković is a traditional representative of migration literature because he experienced migration himself and reflects his experiences in his work. Music plays a crucial role in both his novels and appears primarily in the form of explicit references to various Yugoslavian and English singers and songs on the text level. These references work in various ways: they emphasize the difference between East and West, characterize the protagonist, illustrate the atmosphere of the situation, enable the reader to identify with the characters and, last but not least, support the authentic tone of the text, which is a typical feature of migration literature.
Jødeforfølgelse Med Socialistisk Fortegn. Janina Katz’ Forfatterskab Mellem Polen Og Danmark Med Særligt Henblik På Romanen Putska
Authors: Wolgast Karin
Published: January 2020

Introducing life and work of Janina Katz, the article undertakes an analysis and interpretation of her second novel, the autofictional Putska. Born on the second of March 1939, Katz belonged to a renowned Jewish family with numerous members, of whom, however, only her mother and she survived the Second World War. Their extraordinary family history may be traced in practically all of Katz’ writings, as can her Jewish cultural heritage. The novel Putska is no exception. Its composition, characters and the image it gives of life in Cracow are examined in order to make understandable the protagonist’s decision to exile herself from Poland and migrate to Denmark, much like the author herself. 1969, having fled from that revival of anti-Semite harassment which was launched by the political leadership of socialist Poland, Katz was granted asylum in Denmark, where she soon learned the language to a perfection which enabled her to unfold a widely acknowledged literary work which does not cease to speak of her unique life experience. Central perspectives on her life and work include migration, autobiography, Jewishness and social and cultural history of Poland.
Indirekta Anaforer I Inlärarsvenska: Analys Av Korta Texter Skrivna Av Svenskstuderande I Polen
Authors: Kołaczek Natalia
Published: January 2020

Definiteness appears to be one of the most difficult categories for learners of Swedish. Particularly difficult are the so-called indirect anaphors, definite noun phrases without any explicit antecedent in text. The choice of a definite noun phrase in such contexts requires language skills on a higher level and even some general knowledge about the world. Such phrases make a very nuanced category, yet they are marginalised in textbooks for learning Swedish. This paper presents the results of a study conducted among a group of Polish students of Swedish at the Adam Mickiewicz University in Poznań. The analysis considers noun phrases used in contexts for indirect and direct anaphors excerpted from short texts written by the students based on a picture story. The results reveal that the students’ use of indirect anaphors is not stable. It can be assumed that indirect anaphors concerning body parts are easier to acquire for the learners. Another important factor is the relation of possession between anaphors and triggers. Students often omit the suffixed definite article in context for both indirect and direct anaphors. The study is included in my doctoral thesis written on this topic.
Setninger I Norsk Og Polsk – Definisjoner Og Inndelinger
Authors: Janik Marta Olga , Szymańska Oliwia , Łukaszewicz Barbara
Published: January 2020

In this article we give a brief summary of how Norwegian and Polish sentences are classified in the widely acknowledged grammar books. Therefore, we review the definitions of sentences in both languages, and compare the various classifications applied in Norwegian and Polish. Additionally, much focus is given to classification of sub clauses, which happen to be differently characterized in the respective languages. We would claim that there is a significant bias regarding features that determine classification of sub clauses in Norwegian and Polish. While in Norwegian a lot of emphasis is put on structural features, focusing on how particular units are organized within a sentence, the Polish classifications seem more semantic-oriented. As far as grammatical terms are concerned, Norwegian is featured by far more notions that might yield intransparency for a Polish learner or grammarian. On the other hand, the Norwegian classifications seem far more transparent. Due to a lack of 1-1 relation between terms used in Norwegian and Polish, we cater for this need by providing terms applicable for both languages. We believe that this may come into useful for all who try to systematize their knowledge about sentences in both languages.
“It's Not the Whole Truth”. The Notions of Truth and Falsehood as Persuasive Devices in Polish and Swedish Parliamentary Talk
Authors: Domeradzka Magdalena
Published: January 2020

The article analyses references made to the notion of truth and falsehood in Swedish and Polish parliamentary talk. The results show that despite the mainstreaming of post-structuralism in contemporary society, the notion of truth – the central question of Western philosophy – is still present the parliamentary talk and in the ways in which MPs deliberate and engage in arguments. As the article argues, the MPs deploy discursive strategies exploiting mostly the classical or early modern objective theories of truth. Seeing truth as the ultimate value makes it expedient as a persuasive device and part of epideictic oratory. Apart from the similarities found in the Swedish and Polish parliamentary talk, the article shows differences mainly in how directly an accusation of lying can be voiced in the two parliaments.
“Talking” Containers. Visual Heterotopias in the Picture-Books Illustrated by Svein Nyhus
Authors: Dymel-Trzebiatowska Hanna
Published: January 2020

The article discusses picturebooks illustrated by a Norwegian artist, Svein Nyhus, to show his specific symbolic manner of depicting the child’s environment. It is argued that the illustrator employs characteristic recurrent elements of home representations and elaborates an interesting interplay of outer and inner spaces, consistently focusing the child’s perspective. This is demonstrated by an analysis of four picturebooks by the Norwegian artist: Pappa! (1998, Daddy!), Snill (2002, Nice), Sinna mann (2003, Angry Man) and Håret till mamma (2007, Mum’s Hair). The books have been regarded as ambitious literature for children, addressing difficult issues or even sometimes breaking a taboo. To show Nyhus’ visual method of thematising childhood’s traumas in relation to a home space is also one of the aims of the paper. The analysis of visual content is carried out with references to the textual narratives, drawing on ideas about heterotopia by Michel Foucault (1984), self-effacement by Karen Horney (1997) and the poetics of space by Gaston Bachelard (1969).
The Appearance of Truth – The Truth of Appearance Steen Steensen Blicher: Præsten I Vejlby
Authors: Gergye László
Published: January 2020

The paper discusses a piece by one of the most outstanding Danish short story writers of the 19th century, structured around the convential elements of detective stories. Relying on Jean Baudrillard’s simulacra theory, it attempts to demonstrate the process of how the intriguer Morten Bruus, by a successful use of make-believe, manages to incriminate a pastor, Søren Qvist, in a murder although he is innocent. Bruus’s manipulative strategy prevails in the end: he succeeds at deceiving both his environment and the judge presiding in the case, and the accused is executed. The truth is revealed only twenty years later when Niels Bruus, long thought to be dead, returns. Drawing on Derrida’s legal philosophy, the analysis seeks to expose the problematic nature of justice on earth, and it shows by revisiting certain ideas of Kierkegaard that even in the shadow of death, steadfast faith in divine justice can get us over our fears and the eternal uncertainty deriving from the essence of human existence.
