Anticancer Activity of Amb4269951, a Choline Transporter-Like Protein 1 Inhibitor, in Human Glioma Cells
Authors: Watanabe Saiichiro , Nishijima Nozomi , Hirai Kaho , Shibata Kaoru , Hase Akane , Yamanaka Tsuyoshi , Inazu Masato
Published: May 2020

Choline transporter-like protein 1 (CTL1) is highly expressed in glioma cells, and inhibition of CTL1 function induces apoptotic cell death. Therefore, CTL1 is a potential target molecule for glioma therapy. Here, we investigated the therapeutic mechanism underlying the antitumor effects of Amb4269951, a recently discovered novel CTL1 inhibitor, in the human glioma cell line U251MG, and evaluated its in vivo effects in a mouse xenograft model. Amb4269951 inhibited choline uptake and cell viability and increased caspase-3/7 activity. CTL1-mediated choline uptake is associated with cell viability, and the functional inhibition of CTL1 by Amb4269951 may promote apoptotic cell death via ceramide-induced suppression of the expression of survivin, an apoptotic inhibitory factor. Finally, Amb4269951 demonstrated an antitumor effect in a mice xenograft model by significantly inhibiting tumor growth without any weight loss. Amb4269951 is the lead compound in the treatment of glioma and exhibits a novel therapeutic mechanism. These results may lead to the development of novel anticancer drugs targeting the choline transporter CTL1, which has a different mechanism of action than conventional anticancer drugs against gliomas.
Nostalgia and the ‘New Visibility’ of Religion
Authors: Deacy Christopher
Published: May 2020

This article examines the role that religion plays in a sample of the lives and career journeys of eight academic staff or alumni at a British university. Using the ‘Nostalgia Interviews with Chris Deacy’ podcast as source material, the aim is to look at the intersection between traditional and implicit conceptualisations of religion, that arise in the course of interviews that the author has undertaken, with a view to shedding light on what this says about the role that religion plays when people reminisce about their past, how this relates to contemporary religious experience for them, and whether this might be identified as an example of the ‘new visibility’ of religion. It will conclude that the way we understand the location and parameters of religion in the contemporary world needs to be re-orientated and re-framed, in the light of the presence of those less formal and structured forms of religion, which often overlap with formal religious practices, but are often articulated without reference to it.
Residual Energy Analysis in Cognitive Radios with Energy Harvesting UAV under Reliability and Secrecy Constraints
Authors: Khalid Waqas , Yu Heejung , Noh Song
Published: May 2020

The integration of unmanned aerial vehicles (UAVs) with a cognitive radio (CR) technology can improve the spectrum utilization. However, UAV network services demand reliable and secure communications, along with energy efficiency to prolong battery life. We consider an energy harvesting UAV (e.g., surveillance drone) flying periodically in a circular track around a ground-mounted primary transmitter. The UAV, with limited-energy budget, harvests radio frequency energy and uses the primary spectrum band opportunistically. To obtain intuitive insight into the performance of energy-harvesting, and reliable and secure communications, the closed-form expressions of the residual energy, connection outage probability, and secrecy outage probability, respectively, are analytically derived. We construct the optimization problems of residual energy with reliable and secure communications, under scenarios without and with an eavesdropper, respectively, and the analytical solutions are obtained with the approximation of perfect sensing. The numerical simulations verify the analytical results and identify the requirements of length of sensing phase and transmit power for the maximum residual energy in both reliable and secure communication scenarios. Additionally, it is shown that the residual energy in secure communication is lower than that in reliable communication.
Remote Monitoring of Human Vital Signs Based on 77-GHz mm-Wave FMCW Radar
Authors: Wang Yong , Wang Wen , Zhou Mu , Ren Aihu , Tian Zengshan
Published: May 2020

In recent years, non-contact radar detection technology has been able to achieve long-term and long-range detection for the breathing and heartbeat signals. Compared with contact-based detection methods, it brings a more comfortable and a faster experience to the human body, and it has gradually received attention in the field of radar sensing. Therefore, this paper extends the application of millimeter-wave radar to the field of health care. The millimeter-wave radar first transmits the frequency-modulated continuous wave (FMCW) and collects the echo signals of the human body. Then, the phase information of the intermediate frequency (IF) signals including the breathing and heartbeat signals are extracted, and the Direct Current (DC) offset of the phase information is corrected using the circle center dynamic tracking algorithm. The extended differential and cross-multiply (DACM) is further applied for phase unwrapping. We propose two algorithms, namely the compressive sensing based on orthogonal matching pursuit (CS-OMP) algorithm and rigrsure adaptive soft threshold noise reduction based on discrete wavelet transform (RA-DWT) algorithm, to separate and reconstruct the breathing and heartbeat signals. Then, a frequency-domain fast Fourier transform and a time-domain autocorrelation estimation algorithm are proposed to calculate the respiratory and heartbeat rates. The proposed algorithms are compared with the contact-based detection ones. The results demonstrate that the proposed algorithms effectively suppress the noise and harmonic interference, and the accuracies of the proposed algorithms for both respiratory rate and heartbeat rate reach about 93%.
Selfishness in Vehicular Delay-Tolerant Networks: A Review
Authors: Rehman Ghani-Ur , Ghani Anwar , Muhammad Shad , Singh Madhusudan , Singh Dhananjay
Published: May 2020

Various operational communication models are using Delay-Tolerant Network as a communication tool in recent times. In such a communication paradigm, sometimes there are disconnections and interferences as well as high delays like vehicle Ad hoc networks (VANETs). A new research mechanism, namely, the vehicle Delay-tolerant network (VDTN), is introduced due to several similar characteristics. The store-carry-forward mechanism in VDTNs is beneficial in forwarding the messages to the destination without end-to-end connectivity. To accomplish this task, the cooperation of nodes is needed to forward messages to the destination. However, we cannot be sure that all the nodes in the network will cooperate and contribute their computing resources for message forwarding without any reward. Furthermore, there are some selfish nodes in the network which may not cooperate to forward the messages, and are inclined to increase their own resources. This is one of the major challenges in VDTNs and incentive mechanisms are used as a major solution. This paper presents a detailed study of the recently proposed incentive schemes for VDTNs. This paper also gives some open challenges and future directions for interested researchers in the future.

Authors: Silva Nuno P. , Bottiglieri Anna , Conceição Raquel C. , O’Halloran Martin , Farina Laura
Published: May 2020

Electromagnetic-based hyperthermic therapies induce a controlled increase of temperature in a specific tissue target in order to increase the tissue perfusion or metabolism, or even to induce cell necrosis. These therapies require accurate knowledge of dielectric and thermal properties to optimise treatment plans. While dielectric properties have been well investigated, only a few studies have been conducted with the aim of understanding the changes of thermal properties as a function of temperature; i.e., thermal conductivity, volumetric heat capacity and thermal diffusivity. In this study, we experimentally investigate the thermal properties of ex vivo ovine liver in the hyperthermic temperature range, from 25 °C to 97 °C. A significant increase in thermal properties is observed only above 90 °C. An analytical model is developed to model the thermal properties as a function of temperature. Thermal properties are also investigated during the natural cooling of the heated tissue. A reversible phenomenon of the thermal properties is observed; during the cooling, thermal properties followed the same behaviour observed in the heating process. Additionally, tissue density and water content are evaluated at different temperatures. Density does not change with temperature; mass and volume losses change proportionally due to water vaporisation. A 30% water loss was observed above 90 °C.

Authors: Vogt Dominik Walter , Jones Angus Harvey , Leonhardt Rainer
Published: May 2020

The terahertz spectrum provides tremendous opportunities for broadband gas-phase spectroscopy, as numerous molecules exhibit strong fundamental resonances in the THz frequency range. However, cutting-edge THz gas-phase spectrometer require cumbersome multi-pass gas cells to reach sufficient sensitivity for trace level gas detection. Here, we report on the first demonstration of a THz gas-phase spectrometer using a sub-wavelength thick ultrahigh-Q THz disc microresonator. Leveraging the microresonator’s ultrahigh quality factor in excess of 120,000 as well as the intrinsically large evanescent field, allows for the implementation of a very compact spectrometer without the need for complex multi-pass gas cells. Water vapour concentrations as low as 4 parts per million at atmospheric conditions have been readily detected in proof-of-concept experiments.
A Comparison of Different Counting Methods for a Holographic Particle Counter: Designs, Validations and Results
Authors: Brunnhofer Georg , Hinterleitner Isabella , Bergmann Alexander , Kraft Martin
Published: May 2020

Digital Inline Holography (DIH) is used in many fields of Three-Dimensional (3D) imaging to locate micro or nano-particles in a volume and determine their size, shape or trajectories. A variety of different wavefront reconstruction approaches have been developed for 3D profiling and tracking to study particles’ morphology or visualize flow fields. The novel application of Holographic Particle Counters (HPCs) requires observing particle densities in a given sampling volume which does not strictly necessitate the reconstruction of particles. Such typically spherical objects yield circular intereference patterns—also referred to as fringe patterns—at the hologram plane which can be detected by simpler Two-Dimensional (2D) image processing means. The determination of particle number concentrations (number of particles/unit volume [#/cm 3 ]) may therefore be based on the counting of fringe patterns at the hologram plane. In this work, we explain the nature of fringe patterns and extract the most relevant features provided at the hologram plane. The features aid the identification and selection of suitable pattern recognition techniques and its parameterization. We then present three different techniques which are customized for the detection and counting of fringe patterns and compare them in terms of detection performance and computational speed.

Trends of Research on Supply Chain Resilience: A Systematic Review Using Network Analysis
Authors: Rha Jin Sung
Published: May 2020

Researchers have defined resilient supply chain management in various ways and have analyzed and explained it using many managerial theories. Thus, identifying trends in existing studies could serve as a foundation for future supply chain resilience studies. However, despite the accumulation of a wide body of literature on resilient supply chains, few studies have analyzed the research trends systematically. Therefore, the present study aimed to synthesize and summarize research trends in the supply chain resilience domain using network analysis. The Scopus database and Google Scholar were used to search for research articles on supply chain resilience. We conducted an analysis by visually representing coauthorship, cocitation, PageRank, and keyword networks for 825 research articles and 1725 authors. This study identified the main topics, key articles, and major author groups of supply chain resilience research. The findings are expected to help expand the scope of research to a wide range of subfields in supply chain resilience research in the future.

Authors: Tinoco-Giraldo Harold , Torrecilla Sánchez Eva María , García-Peñalvo Francisco José
Published: May 2020

Mentoring in higher education helps learners acclimate to a new academic topic, increases the likelihood of academic success, and reduces attrition. Learners rely on the expertise and experience of mentors to help them graduate in a timely manner and advance on to their career. As online and distance education becomes more pervasive, computer-mediated mentoring allows learners to connect with their mentors in new ways. Research about mentoring in higher education includes investigations into the efficacy of virtual or e-mentoring. We conducted a literature review of research from 2009 to 2019 to identify relevant elements for implementing e-mentoring programs in higher education. Our research revealed that there is a consistent interest in the subject matter within educational research; however, there is a gap on virtual mentoring in higher education for students conducting offsite internships. Our research reviews e-mentoring programs, identifies how these programs are evaluated, identifies factors of successful programs, and establishes a research agenda in areas of e-mentoring programs for students in offsite internships and how they can be structured to achieve the same level of success.
Assessing the Impacts of Urban Expansion on Habitat Quality by Combining the Concepts of Land Use, Landscape, and Habitat in Two Urban Agglomerations in China
Authors: Wang Huina , Tang Lina , Qiu Quanyi , Chen Huaxiang
Published: May 2020

Understanding the spatiotemporal variability of habitat quality as a function of land-use changes is important for expanding scientific knowledge of ecological conservation. In this study, the impacts of land-use change on habitat quality were assessed in two urban agglomerations in China at different stages of development, namely (1) the Yangtze River Delta Urban Agglomeration (YRDUA), which has reached the middle and late stage of urbanization, and (2) the Golden Triangle of Southern Fujian (GTSF), which has reached the middle and early stage. The Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) habitat quality model was applied to determine the habitat quality and the degree of habitat degradation in these two agglomerations. Overall, the habitat quality in the YRDUA was found to be clearly inferior to that in the GTSF. In the GTSF, more than 65% of the habitat was of good or excellent quality, whereas in the YRDUA, less than 45% of the habitat reached this quality. By combining the concepts of land use, landscape, and habitat, the boundary of degradation and the general increase in habitat quality from 2000 to 2015 were found to be mainly related to the landform, the dominant landscape, and the concentration of non-habitat areas. Additionally, the type, distribution, and fragmentation of the dominant habitat were shown to play important roles in habitat quality. Moreover, changes in industrial composition over time were demonstrated to be critical drivers of changes in areas of construction land.
Significance of Black Hole Visualization and Its Implication for Science Education Focusing on the Event Horizon Telescope Project
Authors: Yoon Hye-Gyoung , Park Jeongwoo , Lee Insun
Published: May 2020

In recent years, substantial progress has been made in black hole visualization. However, there is a lack of essential up-to-date information regarding black holes in current school curricula, in spite of students’ substantial interest in black holes. In this study, we examined the implications of the Event Horizon Telescope project, a recent achievement of the scientific community, for science education. An analysis of the black hole visualization research process, based on Giere’s scientific reasoning model, revealed that there are two categories of the black hole visualization processes: visualization through prediction based on a theory and visualization through real-world observation data. Black hole images are not merely scientific outputs that students must memorize; rather, they can be a useful resource for learning the nature of science and the characteristics of scientific reasoning.

Published: May 2020

In this short communication, the erosion process of the fine, cohesive sediment collected from the upper River Taw in South West England was studied in a rotating annular flume located in the National Water Research Institute in Burlington, Ontario, Canada. This study is part of a research project that is underway to model the transport of fine sediment and the associated nutrients in that river system. The erosion experimental data show that the critical shear stress for erosion of the upper River Taw sediment is about 0.09 Pa and it did not depend on the age of sediment deposit. The eroded sediment was transported in a flocculated form and the agent of flocculation for the upper River Taw sediment may be due to the presence of fibrils from microorganisms and organic material in the system. The experimental data were analysed using a curve fitting approach of Krone and a mathematical model of cohesive sediment transport in rotating circular flumes developed by Krishnappan. The modelled and measured data were in good agreement. An evaluation of the physical significance of Krone’s fitting coefficients is presented. Variability of the fitting coefficients as a function of bed shear stress and age of sediment deposit indicate the key role these two factors play in the erosion process of fluvial cohesive sediment.

Published: May 2020

This paper explores the stories of student entrepreneurs in order to understand 1) their motivation for pursuing student entrepreneurship, 2) their entrepreneurial engagements, and 3) their entrepreneurial challenges including how they balance entrepreneurship and academic work. The study uses a qualitative research design involving a total of twenty graduates of visual arts academic programs in Ghana; respondents were sampled using a purposive and snowball approach. Data collection was carried out with the help of a semi-structured interview guide and data analysis was conducted using a thematic analysis approach. Findings show that most respondents chose to pursue entrepreneurship while studying as early as senior high school level as an avenue for addressing personal financial constraints. Results indicated a preference for entrepreneurial activities in multiple art related industries for most respondents with sectors such as graphic communication design and t-shirt printing dominating. Further, responses show that respondents faced financial, operational, marketing, and managerial challenges in their entrepreneurial pursuits. It is concluded that students in our sample capitalize on the skills they acquire as part of their education to pursue predominantly craft entrepreneurship as a survival strategy. Their entrepreneurial engagements mostly focus on opportunities in their field of specialization with general and context specific challenges confronting them. It is recommended that policy makers in academia, industry, and government work together towards positioning student entrepreneurs to be growth oriented even when choosing the craft route to entrepreneurship.

Published: May 2020

Background. Periodontitis can lead to progressive destruction of periodontal tissues supporting the tooth. Developing biomaterials for tissue engineering has noticeably improved the existing treatment options. The present study investigated the gelatin-hydroxyapatite nano-fibers as promising scaffolds for guided tissue regeneration (GTR). Methods. The scaffolds were prepared through electrospinning technique, and then the physicochemical properties and the cytotoxic effects on dental-derived mesenchymal stem cells were assessed. Results. The nano-scaffolds were successfully prepared with a mono-dispersed nano-scale diameter (102±0.10 nm), negative surface charge (-20±0.17 mV), and uniform network-shaped morphology. The mesenchymal stem cells derived from the human dental pulp stem cells (hDPSC) with gelatin-hydroxyapatite nano-fibers showed that the prepared scaffolds had a significant proliferative effect. Besides, the applied method can be used to prepare fiber-based structures via other polymeric materials. Conclusion. The incorporation of different materials to decrease the degradation rate of the fibers can match the speed of tissue regeneration. In this case, the prepared nano-fibers can be applied as a membrane biomaterial.

Published: May 2020

Background. The present study aimed to evaluate the osteopromoting ability of human tooth powder and compare it to a bovine xenograft, a synthetic material, and the DFDBA allograft. Methods. In this in vitro study, 30 teeth without caries, inflammation, and infection, which had been extracted for orthodontic reasons, were collected. The crowns were removed, pulpectomy was carried out, and the samples were ground to a powder with particles <500 µm. Osteoblast-like cells of MG-63 were cultured with the tooth powder, Cerabone, DFDBA, and Osteon II. Cell proliferation was assessed by the MTT assay at 24- and 72-hour intervals. The alizarin red test was carried out after three and five days. The alkaline phosphatase level was measured after 24, 48, and 72 hours to assess the osteoblastic activity. The results were analyzed with one-way ANOVA. Results. According to the MTT assay, all the materials exhibited a higher proliferation rate than the control group in 24 hours. In 72 hours, DFDBA had the lowest cell proliferation rate at concentrations of 40 and 80 mg/mL. DFDBA and the positive control group were able to create calcified nodules by the alizarin red test. At the 48- and 72-hour intervals, DFDBA had the lowest alkaline phosphatase activity at a concentration of 40 mg/mL. At the 72-hour interval, bovine xenograft had the highest alkaline phosphatase level, followed by the synthetic material and tooth powder. Conclusion. The tooth powder was able to increase cell proliferation in comparison with the bovine xenograft, the synthetic graft, and the DFDBA. However, its osteopromoting ability was less than that of the osteogenic materials.

Published: May 2020

Background. This study aimed to assess the association of haptoglobin (HP) and natural resistance-associated macrophage protein 1 (NRAMP1) alleles with the presence of heme-consuming periodontal pathogens in a group of Iranian patients with chronic periodontitis and peri-implantitis. Methods. This cross-sectional study evaluated 69 eligible chronic periodontitis and peri-implantitis patients selected from Shahid Beheshti Dental School. The periodontally diseased individuals had at least three teeth with clinical attachment loss of ≥3 mm and a probing pocket depth (PPD) of ≥3 mm in at least two quadrants. Peri-implant PPD of at least one site was ≥5 mm with or without suppuration and bleeding on probing. A plaque index of >20% and a radiographic crestal bone loss was present in at least one site around the implant. The paper point method was used for sampling from the deepest periodontal/peri-implant pocket of each tooth or implant for the DNA checkerboard hybridization technique. Statistical analyses were performed with PASW Statistics 18.0. The variables were presented as absolute and relative frequencies (%). Results. An Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) score of 1–2 was 5.8 times more frequent in HP 2, rs1723540 G, and rs2276631 G alleles. A Porphyromonas gingivalis (P. gingivalis) score of 1–2 was 4.8 times more common in the subjects carrying HP 2, rs1723540 G, and rs2276631 G alleles compared with HP 1, rs1723540 A, and rs2276631 A alleles. Conclusion. Within the limitations of this study, it seems that there was a relationship between HP and NRAMP1 allele frequencies and the presence of heme-consuming periodontal pathogens in the Iranian patients with chronic periodontitis and peri-implantitis evaluated in the present study.

The model of optimal enterprise maturity management in the conditions of noisy source data
Authors: Dorrer M.G.
Published: May 2020

The purpose of this work is to propose a mathematical model of the optimal process for managing the organization›s maturity levels in the presence of interference in the source data. Changes in the organizational maturity of a company are described in terms of linear dynamic management systems. The proposed methodology for optimal management of the organization’s maturity level is demonstrated by the example of evaluating and forecasting the maturity level of one of the departments of a technical university. Baseline data is collected by assessing organizational maturity over several years. The paper uses the Kalman-Letov method of analytical design of optimal controllers, as well as a Kalman recursive filter that estimates the state vector of a dynamic system based on a number of incomplete and noisy data. The constructed model demonstrates plausible behavior in predicting the process of managing organizational maturity. The effect of accelerated growth of controlled indicators, identified as priority ones in the model, is reproduced. Using the Kalman filter allows you to create a control effect on the dynamics of organizational maturity indicators in such a way that the target values of maturity levels are achieved even in conditions significantly distorted when measuring the source data.

Published: May 2020

The COVID-19 pandemic has caused unprecedented damage to the educational system worldwide. Besides the measurable economic impacts in the short-term and long-term, there is intangible destruction within educational institutions. In particular, teachers – the most critical intellectual resources of any schools – have to face various types of financial, physical, and mental struggles due to COVID-19. To capture the current context of more than one million Vietnamese teachers during COVID-19, we distributed an e-survey to more than 2,500 randomly selected teachers from two major teacher communities on Facebook from 6th to 11th April 2020. From over 373 responses, we excluded the observations which violated our cross-check questions and retained 294 observations for further analysis. This dataset includes: (i) Demographics of participants; (ii) Teachers' perspectives regarding the operation of teaching activities during the pandemic; (iii) Teachers' received support from their schools, government bodies, other stakeholders such as teacher unions, and parents' associations; and (iv) teachers' evaluation of school readiness toward digital transformation. Further, the dataset was supplemented with an additional question on the teachers' primary source of professional development activities during the pandemic.
Pandemic Awareness Survey in Learning Respiratory System for Junior High School Students for Students' Preparedness in Facing Outbreaks in the Respiratory System
Authors: Husnanda Arsy
Published: May 2020

Science learning requires students to understand the state of their environment and be aware of the dangers that might threaten them such as epidemics in the respiratory system. The plague that attacks the respiratory system is covid-19 with a high mortality and spread rate. The outbreak threatens the lives of people including students as children or adolescents who are more susceptible to the disease. This study aims to determine the pandemic awareness of junior high school students who have studied the respiratory system for covid-19 outbreaks.
Marka: reporter. O widoczności medialnej Mariusza Szczygła
Authors: Żyrek-Horodyska Edyta
Published: May 2020

Niniejszy artykuł poświęcony jest omówieniu strategii kreowania mar­ki osobistej przez reportera Mariusza Szyczygła. Zauważyć można, iż wraz ze wzrastającą popularnością twórczości non-fiction ulega zmia­nie status jej autorów, którzy – wydając kolejne tomy reportażowe – aktywnie angażują się w ich promocję. Jak pokazuje przykład Szczy­gła, wykreowaniu pożądanego przez reportera wizerunku sprzyja jego aktywność w mediach społecznościowych, angażowanie się w liczne działania wykraczające poza działalność stricte dziennikarską, jak też autobiografizowanie dyskursu reportażowego. Strategie te pozwalają istotnie zwiększyć medialną widoczność autora, przekładającą się na jego szerszą rozpoznawalność wśród odbiorców.
Biblical Inspirations in Nikifor’s Paintings
Authors: Wałczyk Krzysztof
Published: May 2020

Nikifor Krynicki (Epifaniusz Drowniak, 1895-1968) was one of the most popular non-academic Polish painters worldwide. To show the biblical inspiration in his creative output I chose two categories from various thematic aspects: self-portraits and landscapes with a church. There are plenty of Nikifor’s paintings showing him as a teacher, as a celebrating priest, as a bishop, or even as Christ. A pop­ular way to explain this idea of self-portraits is a psychological one: as a form of auto-therapy. This analysis is aims to show a deeper expla­nation for the biblical anthropology. Nikifor’s self-portraits as a priest celebrating the liturgy are a symbol of creative activity understood as a divine re-creation of the world. Such activity needs divine inspira­tion. Here are two paintings to recall: Potrójny autoportret (The triple self-portrait) and Autoportret w trzech postaciach (Self-portrait in three persons). The proper way to understand the self-identification with Christ needs a reference to biblical anthropology. To achieve our re­al-self we need to identify with Christ, whose death and resurrection bring about our whole humanity. The key impression we may have by showing Nikifor’s landscapes with a church is harmony. The painter used plenty of warm colors. Many of the critics are of the opinion that Nikifor created an imaginary, ideal world in his landscapes, the world he wanted to be there and not the real world. The thesis of this article is that Nikifor created not only the ideal world, but he also showed the source of the harmony – the divine order.
Negative WoM and its Transmission on OSN: The Determining Role of the Seeding Population
Authors: Messarra Nasri , Mione Anne
Published: May 2020

This paper is a contribution to the knowledge of WoM transmis­sion on OSN. We specifically analyze the role of the seeding popula­tion diffusion of negative WoM. The method is based on an experi­ment on the Facebook fan base of an existing company. We manage to control the four elements of a successful WoM communication: the message, the social structure of the network, the characteristics of the individuals in the network, and the seeding population. We de­velop an original method to dissociate a seeding population from the general population and compare the diffusion of a set of negative messages distributed to both the original population and the artifi­cially targeted subset. Results show the impact of the seeding popu­lation’s characteristics on the diffusion of consumers’ negative mes­sages. We specifically show the impact of the carrier on the virality of the message.
The Spruce in the Culture of the Podhale Shepherds
Authors: Geneja-Pietrzak Barbara
Published: May 2020

In this article I tackle the issue of the worship of spruce trees in the culture of the shepherds in Podhale, a region in southern Poland. This is an issue related to the particular significance of the spruce. It has played a great role in the culture of the whole Podhale region, and es-pecially in the pastoral culture of this area. The spruce was elevated to the rank of a symbol of good luck, prosperity and well‑being. All ac-tivities carried out in the work of shepherds were connected with the ceremonial treatment of spruce trees. It should be noted that these ac-tivities were religiously and magically motivated, as spruce twigs were blessed in the church beforehand. However, this does not change the fact that the rituals were magical. An example would be the custom according to which shepherds would pin spruce or fir twigs to their hats, believing that this would keep them and their sheep were safe. Nowadays, shepherding culture enjoys great interest among research-ers, as well as among Polish and even foreign communities, who apply for participation in shepherding courses organized today. The magic associated with pastoral culture was also reflected in Polish litera-ture and dialect poetry. Readers can refer to the works of such poets and writers as: Seweryn Goszczyński, Kazimierz Przerwa‑Tetmajer, Władysław Orkan, and Stanisław Witkiewicz or dialect poets Wanda Szado‑Kudasi kowa and Roman Dzioboń.
REPRESENTATION OF THE FRAME «MOVING IN SPACE»
THROUGH THE VERBS OF MOVEMENT
IN THE GERMAN LANGUAGE
Authors: Glushak Vassiliy , Vereyutin Vladislav
Published: May 2020

This article discusses MOVING IN SPACE frame in German, defines its concepts and slots that find their language expression through the eight most common verbs of the movement such as gehen, laufen, kommen, wandern, treten, fahren, fliegen, schwimmen.

The basis for constructing the frame is a technique of identifying integral and differential semes. The identified integral semes allowed the authors to define four concepts: the medium of movement; nature of movement; means of

transportation; intensity of movement. Using corpus research based on the COSMAS electronic linguistic corpus,

the study reveals the ability of verbs to express various slots of established concepts. The carried out semantic analysis has made it possible to identify the verbs of movement gradation according to the representation of slots in the frame structure MOVING IN SPACE. The verb with the most extensive semantics is the verb «kommen», since it is able to express the largest number of slots during operation. The dominant concept in the frame structure MOVING IN SPACE is the «medium of movement», since this concept determines the specification of the remaining selected slots. The findings of the analysis are reflected in the cognitive map of the MOVING IN SPACE frame including the set of individual concepts (integral attributes) and slots that implement them (differential semes).
A stressz hatása a szóbeli nyelvi közvetítés minőségére tolmácsvizsgákon
Authors: Besznyák Rita
Published: May 2020

Tolmácsolás közben a nyelvi közvetítés minőségére számos ténye- ző hatással van – a tolmácsnak gyakran változó és kiszámíthatatlan körülmények között kell magas színvonalon teljesítenie, hiszen a kommunikáció sikere múlhat rajta. Mindez komoly stressz-terhelést jelent a tolmácsok számára, ami kétség- telenül rányomja a bélyegét a nyelvi közvetítés minőségére is. Különösen igaz ez a tolmácshallgatók esetében, akiknek a képzésük lezárásaként vizsgán kell számot adniuk az elsajátított ismeretekről és készségekről. Ez a kétszeresen is stresszes helyzet ideális lehetőséget nyújt annak feltérképezésére, hogy a stressznek – az általában vizsgált fiziológiai tüneteken túl – milyen hatása van a nyelvi közvetítés minőségére. Ezt a kutatási célt szem előtt tartva a tanulmány először áttekinti azokat a tényezőket, melyek alapján megítélhető a tolmácsolás minősége, majd számba veszi azokat a külső és belső változókat, melyek hatással lehetnek a tol- mács teljesítményére. Ezen belül is kiemelt hangsúlyt kapnak a tolmácsolandó szöveg nehézségét meghatározó tényezők és a stresszfaktor. A teljesítményszo- rongásból fakadó esetleges minőségromlás konkrét megnyilvánulásainak felderí- téséhez a tanulmány harmadik felében összegzem azokat a szempontokat, ame- lyek a tolmácsteljesítmény értékelésénél megjelennek vizsgahelyzetben. A tanul- mány végén röviden kitérek arra is, hogy az eddigi kutatások fényében milyen lehetséges kutatási irányok körvonalazódnak a jövőre nézve.
Fordítás és tolmácsolás a digitális korban
Authors: Horváth Ildikó
Published: May 2020

A technológiai fejlődés mind a fordítási mind a tolmácsolási piacon érezteti hatását: az új információs és kommunikációs technológiák megjelentek és elterjedtek. A digitális forradalom következtében a hagyományos értelemben vett hivatásos fordítás és tolmácsolás átalakult. A mostani gyorsan változó időkben mélyreható változások tapasztalhatók a piacon a munkakörnyezetben, a munkakö- rülményekben és a folyamatokban, valamint a nyelvi közvetítők tevékenységében, a fordítási folyamatban elvégzendő feladatokban és a nyelvi közvetítők által betöl- tött szerepekben. A jelen tanulmányban a legfontosabb változásokat mutatjuk be, majd a fordítás és tolmácsolás területén tapasztalható fejleményeket vázoljuk fel.
