Effect of Latex Rubber and Rubber Powder as an Admixture on Bending Strength of Cement Mortars
Authors: Rattanaveeranon Santi , Dumrongsil Sarote , Jiamwattanapong Knavoot
Published: May 2019

This paper reported the effect of latex rubber (LR) and rubber powder (RP) on the bending strength of cement mortars containing fly ash silica (FAS) prepared from sugarcane bagasse. The bending strengths of the cement mortars with the addition of LR and RP were compared. The study was conducted by adding 5-10 wt% of each admixture into cement mortar specimens and left in air atmosphere for 28 days before measuring their bending strength. At 5 wt.%, both LR or RP could significantly reinforce the bending strength of the mortar. The bending strength of cement mortars decreased when the proportion of the LR and RP were higher than 5 wt%. In addition, at 10 wt%, LR provided better bending strength than that of RP, i.e. the bending strength of mortar contained LR was 550 ksc, whereas that contained RP was 85 ksc. The bending strength of mortar with LP was much higher than that of the pure cement mortar (20 wt% FAS : 80 wt% cement) which was about 62 ksc. The low bending strength of the mortar with 10 wt% RP may be due to the decrease of Si-O-Si hybrid compounds which was inhibited by the hydroxyl group during the hydrolyzation process.

The magnetic properties of Ba2FeMoO6 (BFMO) double perovskite are investigated. BFMO samples were prepared by solid state reaction method through compression. Magnetic properties are influenced by electron environments of the Fe3+ and Mo5+ ions within the perovskite structure. BFMO sintered at 800 oC exhibited the largest hysteresis loop at 50 K. In addition, the values of Ms and Mr indicate ferromagnetic behaviour in BFMO ceramics sintered at 800 oC for different times up to 10 hours. Using the Curie-Weiss law fitting to investigate μeff~30μB high spin of Fe and Mo, and negative θ present the antiferromagnetic characteristics of the BFMO sample.
Design and Construction of a Mini Magnetic Levitation Train
Authors: Woothipatanapan Sakhon , Wannakarn Poonsri
Published: May 2019

This article presents the design and construction of a mini magnetic levitation train. The design of the train is based on the theory of 3-phase Linear Induction Motor (LIM). The train consists of two main sections. The first part is the linear induction motor, which is the part that drives the train to move. The second part is the magnetic field winding, which is the part that raises the body of the train to float over the rails. Such train can move forward/backward in the same principle as forward/reverse rotation control of 3-phase induction motors. For that reason, this research controls the forward/backward movement of the train with a magnetic contactor set by using the same circuit as the control of the rotation of the 3-phase induction motor. The designed train can lift 1 mm above the rails and move within a distance of 1.48 m along the length of the rails. The test results showed drive voltage, drive force, average time and drive speed of the train. From the details and results of this article can be used as a guide to create a larger magnetic levitation train, which can be used more effectively.

Authors: Ansari Ahmed , Kalyan Sai , Sae-Ngow Treepob , Yamada Yasuhiro , Tanaka Riki , Kawase Tsukasa , Kato Yoko
Published: May 2019

Avoidance of complications during cerebral aneurysm surgery marks the future outcome in the patient. Various modalities such as adequate opening of the Sylvian fissure, motor-evoked potential, endoscope-assisted microsurgery, indocyanine green dye, and dual image video angiography are available to reduce these complications during surgery, either by prevention of injury to the small perforators or the parent artery. We present our experience at the Fujita Health University Banbuntane Hospital, Japan, of the cerebral aneurysm surgery along with the use of these modalities in our patients from September 2014 to December 2016 along with a brief review of the various techniques for avoidance of complications.
Google Translate in Academic Writing Courses?
Authors: Kol Sara , Schcolnik Miriam , Spector-Cohen Elana
Published: May 2019

The aim of this study was to explore the possible benefits of using Google Translate (GT) at various tertiary English for Academic Purposes (EAP) course levels, i.e., to see if the use of GT affects the quantity and quality of student writing. The study comprised preliminary work and a case study. The former included an awareness task to assess student awareness of GT mistakes, and a correction task to assess their ability to correct the mistakes identified. The awareness and correction tasks showed that intermediate students identified 54% of the mistakes, while advanced students identified 73% and corrected 87% of the mistakes identified. The case study included two writing tasks, one with GT and one without. Results showed that when using GT students wrote significantly more words. They wrote longer sentences with longer words and the vocabulary profile of their writing improved. We believe that GT can be a useful tool for tertiary EAP students provided they are able to critically assess and correct the output.

Global deposition of speciated atmospheric mercury to terrestrial surfaces: an overview
Authors: Zhang Lei , Zhou Peisheng , Cao Shuzhen , Zhao Yu
Published: May 2019

Abstract. One of the most important processes in the global mercury biogeochemical cycling is the deposition of atmospheric mercury, including gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM), and particulate-bound mercury (PBM), to terrestrial surfaces. In this paper, methods for the observation of wet, dry, litterfall, throughfall, and cloud/fog deposition and models for mercury dry deposition are reviewed. Surrogate surface methods with cation exchange membranes are widely used for GOM dry deposition measurements, while observation methods for GEM dry deposition are more diverse. The methodology for Hg wet deposition is more mature, but the influence of cloud/fog scavenging is easy to neglect. Dry deposition models for speciated mercury have high uncertainties owing to the presence of sensitive parameters related to GOM chemical forms. Observation networks for mercury wet deposition have been developed worldwide, with the Global Mercury Observation System (GMOS) covering the northern hemisphere, the tropics, and the southern hemisphere. Wet deposition implies the spatial distribution of atmospheric mercury pollution, while GOM dry deposition depends highly on the elevation. Litterfall Hg deposition is crucial to forests. Urban areas have high wet deposition and PBM dry deposition because of high reactive mercury levels. Grasslands and forests have significant GOM and GEM dry deposition, respectively. Evergreen broadleaf forests bear high litterfall Hg deposition. Future research needs have been proposed based on the current knowledge of global mercury deposition to terrestrial surfaces.
Global nighttime atomic oxygen abundances from resampled GOMOS hydroxyl airglow measurements in the mesopause region
Authors: Chen Qiuyu , Kaufmann Martin , Zhu Yajun , Liu Jilin , Koppmann Ralf , Riese Martin
Published: May 2019

Abstract. This paper presents a new dataset of nighttime atomic oxygen density [O], derived from OH(8–4) ro-vibrational band emissions, using a non-local thermal equilibrium model, with the aim of offering new insight into the atomic oxygen abundances in the mesopause region. The dataset is based on the level-1 atmospheric background measurements observed by the GOMOS instrument on board Envisat. Raw data are reprocessed into monthly zonal mean values in 10° latitude bins with a fixed altitude grid of 3 km. The dataset spans from 70° S to 70° N in latitude and from 80 km to 100 km in altitude, covering a time period from May 2002 to December 2011 at local times of from 10 p.m. to 12 p.m. The atomic oxygen density peaks at about 95 km and the highest values are in the range of 3–8 × 1011 atoms cm−3, depending on latitude and season. There is a rapid decrease of [O] below its peak region. The annual oscillation (AO), semiannual oscillation (SAO), and the solar cycle impact are distinguished from the [O] longtime series variations. This new GOMOS [O] dataset conforms to other published datasets and is consistent with the [O] datasets obtained from the SCIAMACHY OH airglow measurements to within about ±20 %.
Understory vegetation relationships with soil element contents in a northern boreal forest ecosystem near a phosphate massif
Authors: Matkala Laura , Salemaa Maija , Bäck Jaana
Published: May 2019

Abstract. We studied the relationship of forest understory vegetation with nutrient contents of soil and tree leaves near Sokli phosphate ore in northern Finland, where the soil contains naturally high variation in phosphorus (P) contents. At most study plots boreal dwarf shrubs, bryophytes and lichen formed a dense mat under a mixture of sparsely growing Pinus sylvestris, Picea abies and Betula pubescens. However, some plots were dominated by B. pubescens and had a higher variety and number of forbs and grasses in the understory. The total P content in the soil humus layer explained the abundance and species composition of the vegetation slightly better than the total nitrogen content. The spatial variation in contents of soil elements was high both between and within plots, emphasizing the heterogeneity of soil. High contents of P in the humus layer (max. 2600 mg kg−1) were measured from the birch-dominated plots. As the P contents of birch leaves and leaf litter were also rather high (2580 mg kg−1 and 1280 mg kg−1, respectively), this may imply that the leaf litter of birch forms an important source of P to the soil.

In-situ measurements of the ice flow motion at Eqip Sermia Glacier using a remotely controlled UAV
Authors: Jouvet Guillaume , van Dongen Eef , Lüthi Martin P. , Vieli Andreas
Published: May 2019

Abstract. Measuring the ice flow motion accurately is essential to better understand the time evolution of glaciers and ice sheets, and therefore to better anticipate the future consequence of climate change in terms of sea-level rise. Although there exist a variety of remote sensing methods to fill this task, in-situ measurements are always needed for validation or to capture high temporal resolution movements. Yet glaciers are in general hostile environments where the installation of instruments might be tedious and risky when not impossible. Here we report the first-ever in-situ measurements of ice flow motion using a remotely controlled Unmanned Aerial Vehicle (UAV). We used a multicopter UAV to land on a highly crevassed area of Eqip Sermia Glacier, West Greenland, to measure the displacement of the glacial surface with the aid of an on-board differential GNSS receiver. Despite the unfortunate loss of the UAV, we measured approximately 70 cm of displacement over 4.36 hours without setting foot onto the glacier – a result validated by applying UAV photogrammetry and template matching techniques. Our study demonstrates that UAVs are promising instruments for in-situ monitoring, and have a great potential for capturing short-term ice flow variations in inaccessible glaciers – a task that remote sensing techniques can hardly achieve.
Non-Communicable Chronic Diseases Among Residents of a Remote Settlement in the Transbaikal Region of the Russian Federation
Authors: Gaisenok Oleg
Published: May 2019

Introduction: Over a quarter of the population of the Russian Federation resides in rural communities. However, the data on chronic disease rates in these communities are limited, which makes screening for chronic diseases extremely important. The aim of this study was to measure the prevalence of chronic noncommunicable diseases among residents of a remote settlement in the Transbaikal region, Russian Federation.Methods: A sample of residents from the Transbaikal region settlement was screened in August 2017. The screening included a survey to determine the frequency of self-reported chronic diseases as well as sociodemographic and behavioral risk factors. Additionally, vascular stiffness was measured by volumetric sphygmography using the VaSera-1500 device. Descriptive statistics have been used for data analysis.Results: 126 residents were screened for this study. The prevalence of chronic non-communicable diseases and their risk factors were: hypertension (56.3%), gastrointestinal diseases (33.3%), chronic obstructive pulmonary disease (13.5%), smoking (35.7%), obesity (19.1%), and diabetes mellitus (6.3%). Pathological vascular changes typical of atherosclerosis were found by volumetric sphygmography in 17.5% of cases, with 5.5% of those cases corresponding to significant forms of severe peripheral atherosclerosis (ABI<0.9). An analysis of mortality causes for this settlement for 2016-2017 found that cardiovascular diseases accounted for over 50% of the total number of deaths.Conclusion: This study showed a high prevalence of detectable chronic non-communicable diseases and their associated risk factors. Cardiovascular diseases were the main cause of mortality. Active prevention programs and screenings are required to reduce the burden of chronic diseases in this region.
Exploring and analyzing the dark Web: A new alchemy
Authors: Faizan Mohd , Khan Raees Ahmad
Published: May 2019

The Tor network is an encrypted network that allows anonymous access to the Internet for its users. The Tor network also hosts hidden services which constitute the infamous dark Web. These hidden services are used to carry out activities that are otherwise illegal and unethical on the surface Web. These activities include distribution of child pornography, access to illegal drugs, and the sale of weapons. While Tor hidden services provide a platform for uncensored ventures and a free expression of thoughts, they are outnumbered by grey activities taking place. In this paper, we have collected the addresses of about 25,742 hidden services and analyze the data for 6,227 available services with the help of custom-made crawler in Python. We analyzed the dataset and manually classify the data into 31 different categories to identify the nature of content available on the dark Web. The results indicate that a large share of hidden services provide illegal content along with a large number of scam sites. Non-English content was also studied and categorized. Russian was the leading language of the dark Web after English and hidden services having forums and blogs were predominantly present over other content.
Ethics of identity in the time of big data
Authors: Brusseau James
Published: May 2019

Compartmentalizing our distinct personal identities is increasingly difficult in big data reality. Pictures of the person we were on past vacations resurface in employers’ Google searches; LinkedIn which exhibits our income level is increasingly used as a dating web site. Whether on vacation, at work, or seeking romance, our digital selves stream together. One result is that a perennial ethical question about personal identity has spilled out of philosophy departments and into the real world. Ought we possess one, unified identity that coherently integrates the various aspects of our lives, or, incarnate deeply distinct selves suited to different occasions and contexts? At bottom, are we one, or many? The question is not only palpable today, but also urgent because if a decision is not made by us, the forces of big data and surveillance capitalism will make it for us by compelling unity. Speaking in favor of the big data tendency, Facebook’s Mark Zuckerberg promotes the ethics of an integrated identity, a single version of selfhood maintained across diverse contexts and human relationships. This essay goes in the other direction by sketching two ethical frameworks arranged to defend our compartmentalized identities, which amounts to promoting the dis-integration of our selves. One framework connects with natural law, the other with language, and both aim to create a sense of selfhood that breaks away from its own past, and from the unifying powers of big data technology.
Revisiting controlled digital lending post-ReDigi

Asymmetric Effect in the Relationship between Oil Prices and Activity: An Estimate of the VECM Model for Eight Emerging Countries
Authors: Djelassi Mouldi , Omrani Mdalla
Published: May 2019

In this study, we attempt to study the impact of oil shocks on the economic activity of eight emerging countries with different importing and exporting profiles, targeting and non-targeting inflation and thus verify the hypothesis of non-linearity. To do this, we used the VECM methodology. In addition to oil prices (the linear variation and its volatility, positive and negative movements in prices), we introduced the interest rate and industrial production as a proxy variable of the activity. The result shows that the economies of these countries are generally more sensitive to net increases in oil prices than to their volatility. Thus, the asymmetrical impact is clearly proven in the results especially in the long run. If the rise in oil prices negatively affects production, the decline does not favor its reshuffle. Indeed, if increases in oil prices reduce economic growth, their declines have no expansionary effect. In addition, the distinction between exporting and importing countries is not obvious. Furthermore, the addition of interest rates indicates that the first prefigurations indicate a tightening of interest rates by the central banks of the target and non-target countries selected in our study.

Published: May 2019

A indústria da construção civil consome vultosos montantes de recursos naturais e gera quantidades significativas de resíduos. Assim, o emprego de materiais alternativos mais sustentáveis é uma condição premente e indispensável. As cinzas processadas, originadas pela combustão de biomassa para geração de energia, são fonte potencial de insumos. Portanto, o objetivo é identificar o nível de progresso das pesquisas científicas sobre o tema, além do método e frequência com que este é abordado. A metodologia consistiu no emprego de técnicas bibliométricas para relacionar publicações enquadradas. Palavras chave específicas fundamentaram o início da busca e filtros foram utilizados para refina-la. Elencou-se, então, informações relativas ao título, autores e resumo das publicações para categoriza-las em função dos métodos de pesquisa. A classificação tipológica dividiu a amostra em dois grupos. O primeiro, que abrange pesquisas com metodologia quantitativa e finalidade experimental, formado por 42 trabalhos e, o segundo, cuja natureza e finalidade dos elementos são, respectivamente, qualitativa e básica, com 9. Os resultados demonstraram haver uma integração da comunidade científica por meio do intercâmbio de informações para avançar na produção de conhecimento. Ademais, constatou-se aumento do número de publicações durante o período analisado, o que indica incremento contínuo na relevância do tema.
ANÁLISE DA RESISTÊNCIA DE SOLO ARENOSO ATRAVÉS DO ENSAIO DE PLACA APÓS A APLICAÇÃO DA TÉCNICA DE BIOCIMENTAÇÃO – MICROBIALLY INDUCED CALCITE PRECIPITATION

Published: May 2019

Devido ao avanço econômico e infraestrutural o aproveitamento de áreas e materiais sustentáveis é necessária, considerando os materiais que possuam propriedades físico-mecânicas necessárias a respectiva empregabilidade em obras de Engenharia. Correlacionando a área da Engenharia Geotécnica, a técnica de melhoramento do solo através da adição de cimento, torna-se inadequada em relação a emissão de CO_2 na atmosfera durante o processo de fabricação do cimento. Assim, outras técnicas de melhoramento de solo são objetivos de estudos, tais quais a MICP (Microbially Induced Calcite Precipitation), na qual realiza um estímulo bacteriano, principalmente das bactérias do tipo Bacillus Pasteurii através da injeção de alimento aos microrganismos presentes no solo, formando assim carbonato de cálcio e por consequência provendo ao solo um aumento da capacidade de carga, através do fenômeno de formação de calcita. Tem-se por objetivo avaliar o comportamento do solo arenoso, formado pela areia de Osório em relação à aplicação da técnica MICP. Mensura-se então tal tratamento através de ensaios de capacidade de carga, no caso em questão utiliza-se o Ensaio de Placa, para obtenção da deformação e ganho de resistência do solo em estudo.
AVALIAÇÃO DO POTENCIAL DE QUARTZO INCOLOR PARA PRASIOLITA DO DISTRITO MINEIRO DE AMETISTA DO SUL
Authors: De Menezes Mauricio Thadeu Fenilli , Duarte Lauren Da Cunha , Juchem Pedro Luiz , Tononi Larissa Lanes
Published: May 2019

O Distrito Mineiro de Ametista do Sul no Estado do Rio Grande do Sul é famoso como um importante fornecedor de ametista, citrino e quartzo hialino. A região é responsável pelo abastecimento do mercado mundial em geodos e pedras para lapidação. Uma minoria do quartzo hialino no mundo tem potencial para obtenção da cor verde (prasiolita) após irradiação. Para avaliação do potencial de prasiolita foi calculado o fator ametista (fa) a partir de espectros FTIR obtidos no Centro Nacional de Desenvolvimento da Tecnologia Nuclear (CDTN). Foram obtidos valores de 1.13 a 1.24. indicando positivamente a obtenção da cor verde após doses de radiação maiores que 900 kGy. Os principais picos de absorbância foram identificados nas bandas 3436 cm-1, 3585 cm-1 e 3595 cm-1. O valor da banda 3436 cm-1 encontrado está relacionada às ligações AlsiOH/Na+, FeSi-OH/H+ e Si-OH (também conhecido como silanol) em quartzo e logo às causas de cor nas amostras. Os cristais foram irradiados em doses de 200 e 900 kGy obtendo-se a cor verde para todas as amostras. Não houve diferença na tonalidade de verde entre as doses de irradiação, indicando que o uso de doses maiores que 200 kGy trazem mais custos aos empreendedores e resultado inócuo. A distribuição da cor não foi homogênea em algumas poucas amostras. Não foi identificada proporcionalidade da intensidade de cor com o fator ametista (fa).
Reflexões sobre a relação de crianças surdas com um recurso digital para a apropriação de língua portuguesa escrita em ambiente escolar
Authors: Lins Heloisa Andreia de Matos , Cabello Janaina
Published: May 2019

A partir de pesquisa anterior sobre a criação de um recurso digital para ensino-aprendizagem de língua portuguesa escrita como segunda língua (L2), o presente artigo busca evidenciar a importância de considerarmos as percepções das crianças (particularmente as surdas, neste caso) para a elaboração conjunta desses materiais. São apresentados alguns registros das interações, em sala de aula, de um grupo de crianças surdas – meninas entre 7 e 11 anos de idade – com o artefato digital desenvolvido, em que se destacam as formas de audiência infantil na relação com o docente surdo e a mídia em questão. Tendo como aportes teóricos a Pedagogia da Infância e os estudos no campo da Filosofia da Diferença, conclui-se que o espaço escolar tem se configurado como local em que tanto o desenvolvimento de recursos didáticos na educação bilíngue de crianças surdas como as práticas pedagógicas nesse sentido são ainda amplamente controlados pelos adultos. Nesse sentido, considera-se a necessidade de tensionar práticas tradicionais de ensino de língua portuguesa como L2 para crianças surdas, uma vez que há possibilidades para fazeres pedagógicos menos normativos na educação bilíngue, a partir do envolvimento das crianças neste processo e de um outro olhar dos pesquisadores e produtores de recursos midiático-tecnológicos nesse ínterim.
Associação entre a periodontite apical e o diabetes mellitus: uma revisão da literatura
Authors: Mendes Liliane Nicolini , Teixeira Mariana Seixas , Michelon Carina , Bello Mariana De Carlo
Published: May 2019

Objetivo: O presente trabalho tem por objetivo realizar uma revisão de literatura buscando verificar a relação entre o diabetes mellitus e a periodontite apical (PA). Revisão da Literatura: A PA caracteriza-se por uma perda óssea na região do ápice dental que decorre principalmente da contaminação do sistema de canais radiculares. Embora a PA seja um processo inflamatório local, na região do periápice radicular, sua progressão pode ser influenciada por patologias sistêmicas, como o diabetes. O Diabetes Melittus é uma patologia crônica em que há alteração na produção de insulina ou resistência à ação da mesma, este hormônio auxilia a manter a concentração normal de glicose sanguínea. O quadro de hiperglicemia crônica presente no paciente diabético descompensado ocasiona alterações fisiológicas, que permitem suspeitar de uma relação entre o diabetes e a progressão de lesões periapicais. Considerações finais: A literatura estudada sugere uma associação positiva entre a presença do diabetes e a progressão de lesões periapicais. Porém apesar dos estudos apontarem que existe uma maior prevalência de periodontite apical em diabéticos ainda são poucas as evidências científicas sobre o assunto.

Employee/Management Sabotage Effects on Organizational Output
Authors: Umana Etebong Attah , Okafor L. C.
Published: May 2019

This study examines how employee sabotage affects organizational output in First Bank Plc, Calabar. The purpose was to identify the causes of employee sabotage, to examine how employee sabotage destroys the image and reputation of the organization, to examine how employee insubordination thwart the achievement of team work accomplishment and organizational effectiveness, to examine how employee refusal to produce product/service affect organizational output and to determine how employee sabotage reduce the security strength of the organization. The study employed survey design and used questionnaire to gather data from sampled respondents. Data was analyzed using simple percentage method. Based on the findings, it was revealed that sabotage at workplace by employee can damage the property, image and reputation of an organization. It was also revealed that employee insubordination thwart the achievement of team work accomplishment and organizational effectiveness. It was equally shown that employee sabotage reduces the security strength of the organization, thus expose the organization to competitive thread and that sabotage by employee leads to waste of resources in the organization, thus low organizational output. It was thus recommended that organizations should do a thorough background checks to know the type of employee that has been hired. Also, organizations should reinforce codes of conduct which will add weight to disciplinary response (court claim) to regulate employees’ behaviours if the employee abuses the rules.

Preparing students for the profession of a teacher involves internships in kindergartens and schools. Learning from practitioners and through practice can be considered in the light of E. Wenger’s theory of situated learning. The article presents the results of research aimed at identifying the experiences of post-graduate students of early-childhood studies related to the peripheral participation in early-childhood teachers communities of practice. The research project was carried out in accordance with the grounded theory, data were collected on the basis of analysis of documents, i.e. student documentation from continuous internships in kindergarten and school, presented in the form of critical events. On the basis of analysis of students’ statements, the barriers to learning from practitioners were identified - for example: encircling by the routine, superficiality activities, cultivating the teacher-expert worship; closing of teachers on modification of their practice; deprecating trainees and their activities, blocking the attempts of students to act differently. The article presents the characteristics of identified blockades, which are illustrated with examples from the collected empirical material.
Czego można nauczyć się z literatury dla dzieci, prezentującej dzieciństwo naznaczone doświadczaniem uchodźstwa?
Authors: Józefowicz Anna
Published: May 2019

After 2016, in Polish literature for children, there appeared a few significant books presenting childhood marked by the most current trauma, namely the experience of refugees. Reading these novels prompted me to ask important questions that I am trying to answer in this paper: How and for what purpose, should we discuss the subject of war trauma with children? How is refugee childhood presented in the analysed literature? How the analysed literature talks about the hardships of war exile refugee families and the “rebuilding” of the house and the whole world by them? I conducted an analysis and interpretation of books based on the assumptions of the concept of humanistic hermeneutics. Using the assumptions of intercultural education simultaneously, I paid attention to the sensitising potential of the analysed literature (development of empathy in the youngest, awakening of conscience, altruistic attitude, provoking discussion on how much we are attentive to the other person).

Befristete Arbeitsverhältnisse in Deutschland und in Polen
Authors: Dabrowski Konrad
Published: May 2019

This book offers a comparison between German and Polish regulations on fixed-term employment contracts against the background of the so-called “flexicurity” strategy of the EU. Despite the partly inverse political and societal circumstances under which these regulations were developed, the author uncovers many parallels, but also some grave differences.

Since atypical employment relationships are to a large extent determined by regulations, it seems obvious to conclude that there must exist a similar level of flexibility and protection with respect to these relationships in the member states. One might therefore formulate the hypothesis that – at least after a certain transitional period encompassing the transposition period and corrections of national legislation according to the case law of the European Court of Justice – the aims of the regulations determining atypical employment relationships in the various member states can be achieved and thus, the respective national regulations should be comparable, at least with respect to their effects. The present work examines the validity of this hypothesis for the two EU member states Germany and Poland on the example of fixed-term employment contracts.
(Im)Possible Tolerance. A Paradox from within Multicultural Societies
Authors: Trupia Francesco ,   Bulgarian Academy of Sciences
Published: May 2019

This paper deals with the principle of tolerance in our contemporary society in the attempt to highlight limits and paradoxes in the various aspects of minority issues. From this point of view, the first part of the paper discusses Kymlicka’s contribution to multiculturalism with regard to national minorities and immigrant communities, while the second part confronts his Theory of Minority Rights with Antonio Gramsci’s theory of hegemony and circle of humanity. Therefore, this paper aims at shifting the discourse over tolerance-related minority issues from a top-down approach toward an analysis of how tolerance is allowed to be performed. Thus, Gramsci’s philosophy of praxis is employed to disentangle moral and cultural set of values and norms within which both principle of tolerance and performativity of toleration are established and, in parallel, to reflect on reasons why others are not allowed to be performed.
The Limits of Tolerance in Perfectionism
Authors: Ajiboro Aderonke ,   Bulgarian Academy of Sciences
Published: May 2019

The responsibility for the wellbeing of people in a community is a germane question in socio-political discourse. I think this is because the aggregation of people in a community does not amount to the aggregation of the same socio-political interest for each and everyone in the community. The mode of organization that a society follows therefore has an impact on how citizens of a particular State attain their wellbeing or the good life. This paper engages the thought that tolerance is an inevitable part of the society, even in a perfectionist state.

According to the oral tradition, four to five degrees of kinship back, at the locality of the village of Batočići, the hamlet of Bare, the municipality of Čajnice – Republic of Srpska in BiH, there was an appearance of a tree with atypical sympodial graft in the spiral or alternating position of annual growth with a different tendency of negative heliotropism. This tree reached a height of up to 20 m and dried at the age of about 170 years. According to the oral tradition, after a longer period, between two and three degrees of kinship backward, the appearance of new single beech trees with the same characteristics in the formation of habit was observed. These new trees appeared successively in a relatively narrow space around the first tree, which for this reason was called the "Mother of Fairy Beech". Morphological characteristics of tree habit in this beech population conform with the variety of "tortuous beech" Fagus sylvatica var. – tortuosa, as well partly conforming to the variety of "weeping beech" Fagus sylvatica var. pendula. In this research, the question of inheritance of irregular sympodial branching with a tendency of negative heliotropism in the population of "Fairy Beech from Čajniče" has been raised, regardless of the characterization of the varieties. Thus, in the population of Fairy Beech from Čajniče, which makes about 40 trees in relatively close surroundings, four trees aged over 30 years have been identified in order to determine whether their tree form is reproduced by vegetative cloning and generatively, by seed. The research was conducted in the period from 2014 to 2016 at the Institute for Genetic Resources of the University of Banja Luka. The results show that the form of habit of all four parent trees are conveyed by branching as well as by seed, which proves that there was a mutation of the first tree, i.e. the mother of Fairy Beech from Čajniče, which is transmitted to the offspring.
Osteopathic Cranial Manipulative Medicine and the Blood-Brain Barrier: A Mechanistic Approach to Alzheimer Prevention
Authors: McAree Michael , Dunn Alexis , Furtado Jared , Timmerman Clinton , Winchell Zachary , Rani Radhika , Farah Jennifer , Crispino Lauren J.
Published: May 2019

Recent studies have demonstrated that blood-brain barrier (BBB) dysfunction may be implicated in the pathogenesis of Alzheimer disease, thus establishing a link between disease manifestation and compromised neurovasculature. The authors identify relationships between Alzheimer disease and BBB breakdown, the response of the BBB to increased cerebral blood flow and shear stress, and the impact of osteopathic cranial manipulative medicine on cerebrovascular hemodynamics. They propose and review a rationale for future research to evaluate osteopathic cranial manipulative medicine as a preventive treatment for patients with illnesses of neurovascular origin.
O założeniach i postulatach lingwistyki kulturowej (na przykładzie definicji PRACY)
Authors: Bartmiński Jerzy
Published: May 2019

Artykuł składa się z czterech części. W pierwszej autor przypomina początki formowania się lingwistyki kulturowej w Polsce, związane z wrocławskim programem badań nad polską kulturą narodową, utworzeniem konwersatorium „Język a kultura” (też serii wydawniczej pod takim tytułem) i lubelskiego rocznika „Etnolingwistyka” w roku 1988. W drugiej podaje przykłady traktowania faktów językowych w perspektywie kulturowej, eksponując rolę słownictwa jako zwierciadła kultury. W trzeciej przedstawia 7-punktowe instrumentarium pojęciowe wypracowane w ramach lubelskiej etnolingwistyki kognitywnej (językowy obraz świata, stereotypy traktowane jako koncepty kulturowe, definicja kognitywna, punkt widzenia i perspektywa interpretacyjna; profilowanie bazowych wyobrażeń; wartości; podmiot doświadczający, konceptualiujący i werbalizujący). Na koniec na przykładzie jednego konceptu PRACA pokazane zostają efekty analizy z zastosowaniem przedstawionego tego instrumentarium pojęciowego.Słowa kluczowe: lingwistyka kulturowa, seria „Język a Kultura”, rocznik „Etnolingwistyka”, lubelska etnolingwistyka kognitywna, językowy obraz świata, koncept kulturowy, praca
Projekt polsko-niemieckiego słownika językowego savoir-vivre'u
Authors: Marcjanik Małgorzata
Published: May 2019

Przedmiotem artykułu jest omówienie powstającego w ramach projektu badawczego polsko-niemieckiego słownika językowego savoir-vivre’u. Przedstawione zostały założenia leksykograficzne tego słownika, źródło materiału oraz struktura hasła. Główny problem badawczy to niemiecka ekwiwalencja funkcjonalna polskich zwrotów grzecznościowych. Metodologia badań oparta jest na założeniach pragmatyki kulturowej. Autorka skupiła się na omówieniu podstawowych różnic przede wszystkim kulturowych i pragmatycznojęzykowych między polską i niemiecką grzecznością językową. Omówione zostały takie problemy, jak: różne w polszczyźnie i w niemczyźnie strategie grzecznościowe, w tym polska strategia podwładnego i strategia męskiej kurtuazji; polski i niemiecki tosowan ejsystem adresatywny; możliwość stopniowania uprzejmości w polskich aktach prośby i częstowania oraz problem niemieckiej ekwiwalencji; wpływ czynników społeczno-politycznych na funkcjonowanie form adresatywnych. Wskazano na taki dodatkowy rezultat powstania słownika, jak możliwość zrekonstruowania na jego podstawie obrazu uprzejmego Polaka i uprzejmego Niemca. Na zakończenie została sformułowana teza, że powstawanie tego typu dwujęzycznych (dwukulturowych) słowników miałoby wpływ na zoptymalizowanie komunikacji międzykulturowej.
„Chleba naszego potrzebnego”. Dyskusja nad nowym szwedzkim tłumaczeniem „Ojcze nasz”
Authors: Plutecka Weronika
Published: May 2019

„Ojcze nasz” to najważniejsza modlitwa chrześcijan. Jako starożytny tekst biblijny od wieków poddawana jest badaniom oraz tłumaczona na nowo wraz z rozwojem języków docelowych. Ze względu na powszechność tej modlitwy i jej wyjątkowy charakter, takie zmiany nie zachodzą niepostrzeżenie – szczególnie w kraju, gdzie odbiorcy tego samego tłumaczenia są członkami różnych społeczności, katolickiej (mniejszościowej) i protestanckiej. Niniejszy artykuł przedstawia specyfikę przekładu tekstów liturgicznych w oparciu o analizę tłumaczeń na język szwedzki. Pokazana zostaje historia szwedzkiego tłumaczenia modlitwy „Ojcze nasz”, aż do opublikowania kontrowersyjnej wersji ekumenicznej w 1996 r. Przeanalizowane zostają wybrane różnice w „starym” i „nowym” tłumaczeniu oraz najważniejsze postulaty w debacie nad przyjęciem wersji ekumenicznej. Artykuł zamyka przytoczenie obecnego stanowiska kościoła katolickiego i protestanckiego wobec nowej wersji oraz dyskusja nad nowoczesnością i tradycją we współczesnych tłumaczeniach Modlitwy Pańskiej. Studium pozwala pokazać w jaki sposób otwartość na zmiany w obszarze przekładu może spowodować poruszenie społeczne i konflikt, jeśli zmiany nie są dostosowane do aktualnych przekonań reprezentantów danej kultury.
O otwartości metafory
Authors: Maliszewski Bartłomiej
Published: May 2019

Artykuł dotyczy otwartości metafory ujmowanej z trzech perspektyw: nadawczej (otwartość metafory jako możliwość kreowania nowych znaczeń i gier semantycznych), odbiorczej (otwartość metafory jako możliwość dokonywania mniej lub bardziej rozległych interpretacji) oraz badawczej (otwartość metafory jako nieostrość granic między znaczeniem dosłownym i przenośnym oraz coraz szerszy sposób ujmowania samego zjawiska metafory).
The k conditional nearest neighbor algorithm for classification and class probability estimation
Authors: Gweon Hyukjun , Schonlau Matthias , Steiner Stefan H.
Published: May 2019

The k nearest neighbor (kNN) approach is a simple and effective nonparametric algorithm for classification. One of the drawbacks of kNN is that the method can only give coarse estimates of class probabilities, particularly for low values of k. To avoid this drawback, we propose a new nonparametric classification method based on nearest neighbors conditional on each class: the proposed approach calculates the distance between a new instance and the kth nearest neighbor from each class, estimates posterior probabilities of class memberships using the distances, and assigns the instance to the class with the largest posterior. We prove that the proposed approach converges to the Bayes classifier as the size of the training data increases. Further, we extend the proposed approach to an ensemble method. Experiments on benchmark data sets show that both the proposed approach and the ensemble version of the proposed approach on average outperform kNN, weighted kNN, probabilistic kNN and two similar algorithms (LMkNN and MLM-kHNN) in terms of the error rate. A simulation shows that kCNN may be useful for estimating posterior probabilities when the class distributions overlap.
