Tabus Linguísticos no léxico religioso: um estudo geolinguístico com base no Atlas Linguístico do Brasil
Authors: Costa Geisa Borges
Published: January 2021

O estudo busca descrever e analisar as denominações utilizadas pelos falantes das capitais do Brasil para nomear o item lexical “diabo”. Para isso, utilizaram-se inquéritos do Projeto Atlas Linguístico do Brasil (ALiB), realizados com 200 informantes, distribuídos equitativamente por ambos os sexos, em duas faixas etárias e dois níveis de escolaridade, selecionados de acordo com os critérios da Dialetologia Contemporânea. Pautando-se nos pressupostos teórico-metodológicos da Geolinguística Pluridimensional, analisou-se a primeira questão do Questionário Semântico-Lexical referente à área semântica da religião e das crenças, com o intuito de documentar a riqueza sinonímica para a variante diabo. Os dados foram coletados através da pergunta: “Deus está no céu e no inferno está ...?”. Foram registrados 506 dados lexicais, concretizados através de 39 variantes: anjo do mal, anjo mau, anticristo, besta, besta-fera, belzebu, bicho feio, bicho ruim, cão, capeta, capiroto, chifrudo, coisa, coisa ruim, cramulhano, criatura, cruz- credo, demo, demônio, desgraça, diabo, didi, encardido, enxofre, estrela vermelha, inimigo, lúcifer, maligno, mefítico, príncipe dos céus, rabudo, sapirico, satã, satangoso, satanás, sujo, tibinga, tinhoso, troço. A análise semântico-lexical revelou uma correspondência entre os recursos linguísticos substitutivos do referente diabo e os tabus linguísticos, registrados através de processos metafóricos, eufemísticos e disfemísticos.

Authors: Campos Carolina Fernanda Cunha , Ferreira Mariana Lettieri
Published: January 2021

O presente artigo configura-se, em termos metodológicos, como um estudo qualitativo de caráter exploratório que integra uma experiência de estágio da pesquisadora e estagiária licencianda em língua inglesa, primeira autora deste artigo, realizada em uma escola municipal da cidade de São Paulo sob a supervisão da pesquisadora e professora-formadora, segunda autora deste artigo. A proposta de estágio envolveu-se nos pressupostos teóricos da pedagogia dos multiletramentos, conforme proposta pelo Grupo de Nova Londres em 1996, além de também terem sido encontrados pontos de convergência com a pedagogia da autonomia conforme proposta por Freire (2016). A vivência formativa aqui relatada, uma sequência de quatro aulas, possibilitou a criação de atividades relevantes para os alunos, pautadas na estrutura da sala de aula, com discussões sobre suas necessidades e análise de diferentes cenários. Além disso, a experiência possibilitou às autoras debates sobre a própria pedagogia dos multiletramentos, a pedagogia da autonomia, as demandas do ensino de inglês na escola e os efeitos do estágio na formação de professores.
ANÁLISE DO DISCURSO E SEGUNDA LÍNGUA: PORTAL 2 NO ENSINO DE VOCABULÁRIO
Authors: Rocha Cruz Fabielle
Published: January 2021

Nas aulas de segunda língua, é muito comum que o professor foque no vocabulário a ser aprendido e o aluno, muitas vezes, carece de contexto e de explicações sobre determinadas palavras ou expressões que têm um sentido muito único ou peculiar, que se conectam com a identidade do falante. Assim, utilizar meios que tragam a língua contextualizada, de modo que o aluno possa utilizar recursos da análise do discurso (AD), como o ethos, para melhor entender a escolha das palavras, é um atrativo. Através de uma revisão bibliográfica dos estudos de AD e de ethos, bem como uma pesquisa do tipo exploratória, o presente artigo propõe-se a analisar a possiblidade de utilizar os jogos digitais, mais especificamente o jogo Portal 2, para mostrar a importância das escolhas lexicais. Através de um quadro com frases do jogo escolhido, aponta-se a conexão entre entonação e identidade da personagem escolhida para adequar e contextualizar os recursos. Por fim, apresenta-se os resultados, observando-se a faixa etária e o conteúdo que faz parte do jogo, entendendo-se que o professor não perde seu papel para o jogo, mas torna-se mediador da aprendizagem.
CURRICULOS ESTADUAIS DO NORDESTE E SUAS PERSPECTIVAS SOBRE AS TECNOLOGIAS DIGITAIS
Authors: Silva Herbert Gomes
Published: January 2021

Este artigo trata da concepção e da relação entre os referenciais curriculares do Ensino Fundamental dos Estados do Nordeste e sua abordagem a respeito da formação na cultura digital, tendo como contexto a suspensão das aulas presenciais, transferindo as relações de ensino e aprendizagem para o uso e mediação das tecnologias digitais. Utiliza como caminho investigativo a triangulação metodológica de Minayo, Assis e Souza, analisando dialogicamente dados quantitativos e qualitativos. Obteve como resultado que, além da falta de acessibilidade aos meios digitais promovidos nos ambientes educacionais, apontados pelas pesquisas quantitativas, os referenciais curriculares, apresentam concepções voltadas para a cultura de usuários acríticos e não contemplam uma formação propícia ao desenvolvimento do pensamento computacional. Condição está que exige políticas públicas de ampliação de condições de acesso e desenvolvimento de currículos e da formação de professores como processos inseparáveis de formação frente aos desafios contemporâneos e para exercício participativo dos estudantes na sociedade.
PRAGMATICS: WHY USE AUDIOVISUAL INPUT IN SECOND AND FOREIGN LANGUAGE LEARNING CONTEXTS?
Authors: Rodríguez Peñarroja Manuel
Published: January 2021

The teaching and acquisition of pragmatics in second and foreign language learning contexts has been traditionally reduced to coursebooks’ decontextualized dialogue samples and static images with almost no effects on learners’ communicative competence. This paper outlines rationale on the teaching of pragmatics since it has become of essential importance as specified in different language proficiency paradigms i.e. the CEFR. Thus, attention is centered on the use of audiovisual materials as a rich input source used for that aim. With this in mind, a review of studies appraising for the validity of language used in audiovisual genres is provided. In addition, an overview of its applicability and effects as a part of the general education curricula and in second and foreign language instruction is presented. Results from the studies reviewed reported overall advantageous outcomes when using this type of input for different instructional aims and more specifically with pragmatics’ acquisition purposes.
O ABANDONO DE TERRAS AGRÍCOLAS NO ESTADO DO RIO DE JANEIRO
Authors: Vidal Mariana Ribeiro , Vicens Raúl Sánchez
Published: January 2021

O Estado do Rio de Janeiro vem passando por uma transição no uso e cobertura do solo, principalmente no que diz respeito às áreas agrícolas, tiveram redução de aproximadamente 72% de sua área plantada em hectares (IBGE, 2017). Este trabalho tem como objetivo identificar padrões espaciais e temporais das áreas plantadas no Estado, estabelecendo mapas de porcentagem de perdas, taxa de crescimento, taxa de aceleração e centro médio da área plantada, além de caracterizar o atual espaço rural fluminense. Verificou-se que há perda em todo o território do Estado, com predomínio de áreas de baixa densidade. Nesse processo, prevaleceu a baixa redução (-50% <x <-5%), que ocorreu em grande parte de forma acelerada e agora mostra desaceleração. Não houve grandes deslocamentos dos centros médios anuais da área plantada. Dessa forma, verifica-se um abandono de terras agrícolas, que pode dar espaço para um novo modelo de desenvolvimento rural, pautado na pluriatividade.

Focused cardiac ultrasound in out-of-hospital cardiac arrest: a literature review
Authors: Brown Nick , Quinn Tom
Published: January 2021

Focused cardiac ultrasound (FoCUS) is emerging in emergency medical systems, particularly in the context of prognostication in out-of-hospital cardiac arrest. However, FoCUS has not been formally incorporated into UK guidelines because of a lack of evidence. Furthermore, concerns have been raised that FoCUS can distract people from providing other essential and evidenced elements of care. This broad literature search aims to shed light on the practice of FoCUS in cardiac arrest by reviewing articles related to in-hospital and out-of-hospital practice. The findings are conspicuous by the lack of high-quality studies, particularly regarding prognostication. Association between ultrasound findings and outcome are asserted, as is the feasibility of paramedic use of FoCUS, although the evidence is from small and non-randomised studies and subject to bias.
Should ascorbic acid be a primary therapy for sepsis in prehospital settings?
Authors: Law Adam
Published: January 2021

Background:

Prehospital emergency medical services (EMS) are believed to be responsible for the initial treatment of 68 000 septic patients annually in the UK, 88% of whom have severely low ascorbic acid levels, which can lead to organ dysfunction, increasing the likelihood of mortality.

Objective:

This review aims to determine if early therapeutic use of ascorbic acid (vitamin C) could reduce the deterioration of septic patients and therefore overall mortality.

Method:

A literature review was conducted using the mySearch, PubMed and Cochrane Library databases. Each was systematically searched for human studies that addressed the use of ascorbic acid as a primary method of treatment during varying stages of sepsis and whether it reduced associated mortality. Studies not published in English or that were more the 5 years old at the time were excluded. The quality of evidence in the remaining articles were appraised using the GRADE method and further assessed for quality with an adjusted Downs and Black scoring tool.

Results:

Nineteen articles were found, three of which met the inclusion criteria. All addressed the use of ascorbic acid as a therapy in the treatment of sepsis; none were conducted in a prehospital setting.

Conclusion:

Intravenous ascorbic acid appears to be a safe and effective therapy in treating septic patients, with the potential to reduce mortality rates if given prophylactically. However, a series of clinical trials would need to be conducted to measure the extent of any improvement and therefore clinical value in the prehospital environment.

Published: January 2021

Eczema is usually managed in primary care. Julie Van Onselen provides an overview of the principles of eczema treatment

Eczema is a common skin condition, which for the majority is managed in primary care. Nurse prescribers should be aware of evidence–based guidelines in eczema treatment, on which they need to base prescribing decisions and work with the patient on individual skin care plans. Education and support in managing eczema is essential for patients of all ages (and carers of children and older people). Eczema has a huge impact on quality of life but a good management plan can make a big difference to controlling eczema, which is a chronic condition. This article explains the principles of eczema treatments, in acute, sub-acute and chronic stages of eczema with emollients, topical corticosteroids, antibiotics, antimicrobials and antivirals, topical calcineurin inhibitors and antihistamines.

Published: January 2021

Objectives:Elevation of free fatty acids (FFAs) in serum is an importantrisk factor for metabolic changes.Conversely, the relationship between obesity and metabolic abnormalities, and FFAsis not yet completely understood.Thus,we aimed in this study to explore the relationship and the association between insulin resistance (IR), metabolic markers and the variation inplasmaFFAs among the obese women. Methods:This study included fifty obese women aged 25–35 years and has insulin resistance (IR)in addition to fifty age-matched healthy normal weightwomen served as control group.Blood was withdrawn after twelve hours fasting;fasting blood glucose, lipidsand plasma insulinwere estimated;IR was assessedvia the Homeostasis Model Assessment-Insulin Resistance (HOMA-IR).Fatty acids in plasma were measured by HPLC using UV detector that was set at 200 nm.Indeed, anthropometric measurements was performed . Results:Lipid profile, fasting blood sugar, insulin resistance, oleic acids (OA), linoleic acid (LA), arachidonic acid (AA) and anthropometric measurements were significantly increased in IR women compared to control. Whereas, the mean value levels of alpha-linolenicacid(ALA)was significantly decreased in IR women compare to controls. Conclusion:lower plasma levels of ALA and higher levels of AA, OA, LA were significantly associated with risk of IR and metabolic disorder markers in obese women.These results might explain the positive benefits of foods rich with poly unsaturated fatty acids (PUFA).Obesity and IR may be associated with the alterations in composition of the circulating fatty acid.These findings underscore the potential role of PUFA in the metabolic syndrome pathogenesis.

Published: January 2021

With the increased number of financial-related malware, the security community today has turned their attention to the Android financial malware. However, what constitutes Android financial malware is still ambiguous. A comprehensive understanding of the existing Android financial malware attacks supported by a unified terminology is necessarily required for the deployment of reliable defence mechanisms against these attacks. Thus, in this paper, we address this issue and devise a taxonomy of Android financial malware attacks. By devising the proposed taxonomy, we intend to: give researchers a better understanding of these attacks; explore the Android financial malware characteristics; and provide a foundation for organizing research efforts within this specific field. In order to evaluate the proposed taxonomy, we gathered a large collection of Android financial malware samples representing 32 families, which are selected based on the main characteristics defined in the taxonomy. We discuss the characterization of these families in terms of malware installation, activation and attacks, and derive a set of research question: how does the malware spread to the Android users?, how does the malware activate itself on the phone?, and what happens after the malware has reached the Android system? Evaluation and characterization of this taxonomic model towards Android financial malware implies the possibility for introducing an automatic malware categorization, which can effectively save the time of malware analysts to correlate various symptoms of malicious behavior; this combination provides a systematic overview of malware capabilities, which can help analyst in the malware-triage process for prioritizing which malware to be scrutinized. Also, we identified a number of challenges related to Android financial malware, which can create opportunity for future research.

Information Flow Control with Decentralized Labeling Model in Information Security
Authors: Hakkoymaz Veli , Bakir Cigdem
Published: January 2021

Data security aims to prevent the use, modification, and spread of data by unauthorized people. In this study, our purpose was to provide data privacy and confidentiality with information flow control in distributed databases. In particular, a decentralized label model was developed that maintained confidentiality, including privacy, with data flow control. This model consists of an actor, an object, and a label. The owners of the objects are actors, and they need to share their data objects with others. Actors label the data objects and then send them out. A label contains the policy statements of data security issued by each of the owners. Each owner sets its own security and privacy policy independently of the other owners. The confidentiality of data in unsecured transport channels is ensured for all the actors in the system by means of labels while the data are in flow. Data objects are spread and shared securely among actors within unsecured environments. In addition, with the path compression, the long node chain that is formed while the data objects are passing between the source node and the destination is broken, so that the objects are retrieved fast, and the cost of access is reduced. This result was shown experimentally by modeling the distributed environment.

Monte Carlo method solution of the broadband fluorescent radiative
transfer equation considering fluorescent cascade
Authors: Yalçın Refet Ali , Ertürk Hakan
Published: January 2021

Altering wavelength via fluorescent particles is used in various
applications. The solution of the broadband radiative transfer
equation (RTE) for absorbing and anisotropically scattering a
fluorescent medium is presented in this study considering fluorescent
cascade, along with a Monte-Carlo-method-based solution of the
equation. The path-length-based Monte Carlo method, the dual-stage
method, and its modified version, the multi-stage method, which are
used for solving the RTE in a fluorescent medium for biomedical and
lighting applications, are not capable of accurately solving the
broadband RTE with fluorescent cascade. Therefore, a collision-based
Monte Carlo method is applied to overcome the limitations of these
approaches. An accuracy comparison with the alternative methods is
presented along with the flow chart and codes of the proposed
method.
Aberration optimization in an extreme ultraviolet lithography projector
via a BP neural network and simulated annealing algorithm
Authors: Zhao Rongbo , Dong Lisong , Chen Rui , Wei Yayi
Published: January 2021

Extreme ultraviolet lithography (EUVL) presents promise for
the advanced technology node in the manufacturing of integrated
circuits. The imaging performance of EUVL is significantly affected by
the aberration of projection optics. To obtain one optimum aberration
for different test patterns, an inverse optimization method for
aberration is proposed in this paper. The aberration models of three
types of test patterns are first established by applying the
backpropagation (BP) neural network. Then choosing the common
indicators of the lithography process variation band (PVB) and pattern
shift (PS) as the objective function, an aberration optimization
method based on the algorithm of simulated annealing is proposed.
After applying the optimization method, a set of optimized aberrations
and the corresponding PVBs and PSs are obtained and analyzed. These
results are finally compared with those from rigorous simulations. The
comparison results show that zero aberration is
non-optimal distribution in EUVL image simulation with mask
topography. In addition, the high prediction accuracy and robustness
of aberration optimization is also demonstrated from the results.

Laser scanning dark-field coherent anti-Stokes Raman scattering (DF-CARS): a numerical study
Authors: Heuke Sandro , Rigneault Hervé
Published: January 2021

We present and model a dark-field illumination scheme for coherent anti-Stokes Raman scattering (DF-CARS) that highlights the interfaces of an object with chemical sensitivity. The proposed DF-CARS scheme uses dedicated arrangements of the pump kp1, Stokes k
S
and probe kp2 beams’ k-wave-vectors to address the sample’s interfaces along the x, y or z axis. The arrangements of the incident k-wave-vectors are derived from the Ewald sphere representation of the outgoing anti-Stokes radiation and the effective CARS excitation wave-vector keff = kp1 + kp2 − k
S
under the intention to avoid probing the object frequency K(0,0,0), i.e., the contribution of a homogeneous sample (dark-field configuration). We suggest a possible experimental realization using simple masks placed in the back pupil of the excitation microscope objective lens. Applying a full vectorial model, the proposed experimental implementation is numerically investigated on grounds of the Debye-Wolff integral and dynadic Green function to confirm the predicted chemical interface contrast.
Time varied illumination laser speckle contrast imaging

Published: January 2021

Laser speckle contrast imaging is a technique to determine blood flow rate with a limitation of low dynamic range. In this Letter, we introduce a varied illumination speckle contrast imaging method. It utilizes varying illumination during exposure to customize the correlation time (flow rate) to speckle contrast relation. The method can cover an order of magnitude larger range flow rate in a single exposure compared to constant illumination methods. The proposed method enables high dynamic range flow rate imaging, which is advantageous in studying larger vessels and small arteries. We demonstrate the theory by simulations and ex vivo and in vivo measurements.

VBA program fejlesztése feladatsorok dokumentumainak generálására
Authors: Fabulya Zoltán
Published: January 2021

Az online oktatás során a távoli számonkérés megkövetelte, hogy olyan új technikákatalkalmazzunk, mellyel minimálisra csökkenthetők az ellenőrzés korlátozottságából adódó visszaélési lehetőségek. Eltérő feladatsorokkal megoldhatjuk, hogy az egyszerre vizsgázók a megoldásaikat egymással megosztva ne tudjanak érdemtelenül több ponthoz jutni. Viszont nagyszámú vizsgázó esetén manuálisan elkészíteni egyedi feladatsorokat nem lehetséges. Olyan VBA programra nyílt igény, mely egy feladattárból állítja össze a kívánt mennyiségben Word dokumentumként a megoldandó feladatsort. Ehhez fel kellett mérni, hogy a feladattár legalább hány feladatot tartalmazzon, milyen szerkezetű legyen. A dokumentumokat generáló programmal elérhető, hogy minden vizsgázó egyedi feladatsort kapjon, melyek bár tartalmazhatnak közös feladatokat, de ezek száma kellően alacsony szinten tartható a feladattár méretétől függően.

Published: January 2021

Over the past two centuries, Altai krai, located in the southeastern part of Western Siberia, has undergone significant transformation as a result of the virgin lands development. The vast even territories of the krai, formerly occupied by steppes dominated by the feather grass, are now almost completely plowed up. Many types of steppe communities, as well as plant species associated with them, have become rare. This paper presents the results of the taxonomic revision of the genus Stipa. The genus has a high conservation value and seven of twelve feather grass species growing in the studied area are listed in the “Red Book of Altai Krai”. Based on the revision of the herbarium collections stored in ALTB, LE, NS, NSK, TK and the authors’ collections, a checklist of the genus Stipa in Altai krai and an illustrated identification key were compiled. The synopsis for each species contains a nomenclature name, a brief description, a note on taxonomy, flowering period and typical habitats. In addition, it presents the distribution of species in the territory of the krai in the form of an administrative districts list and point maps. A new record of S. sareptana species, new for Altai krai and Western Siberia, was found while the presence of S. baicalensis was not confirmed. Additionally, lectotype of S. praecapillata is also here designated.
On taxonomic status of two species of orchids (Orchidaceae) from Turkmenistan
Authors: Fateryga Alexander V. , Pavlenko Alexander V. , Fateryga Valentina V.
Published: January 2021

The orchid genera Epipactis Zinn and Ophrys L. are well-known by their complicated taxonomy and extensive debates over species richness within them. These genera are represented in Turkmenistan by two species each. Two of them, namely E. turcomanica K. P. Popov et Neshat. and O. kopetdagensis K. P. Popov et Neshat., were hitherto accepted as species endemic to Turkmenistan. In the present paper, these taxa are synonymized with broadly distributed E. persica (Soó) Hausskn. ex Nannf. and O. oestrifera M. Bieb., respectively. Thus, the genus Epipactis is represented in Turkmenistan by E. persica and E. veratrifolia Boiss. et Hohen., and the genus Ophrys is represented by O. mammosa Desf. and O. oestrifera. There are no species of orchids endemic to Turkmenistan.
New data on distribution of Cruciferae (Brassicaceae) in Mongolia

Published: January 2021

At the end of the 20th century the flora of Mongolia was considered very well examined. At that time V. I. Grubov (1982) had summarized its study. However, later it became clear that the flora can be thoroughly supplemented (Gubanov, 1996). In the 21st century, it became apparent that many areas of Mongolia require new, more thorough research, not only for clarifying their species diversity, but also for more specifically defining the boundaries of botanic-geographical districts. The first major attempts to combine all floristic publications were the “Conspectus of the vascular plants of Mongolia” (2014) and the first volumes of “Flora of Mongolia” (2015) prepared by the Mongolian botanists. But even these works show that Mongolia remains an endless region for the search and study of botanical novelties. One of the results of such critical search and studies of herbarium collections and field studies in 2019 is presented in this publication, which expands our knowledge on the distribution of 14 cruciferous species (Alyssum desertorum, Cardamine hirsuta, C. macrophylla, C. dentata, Chorispora tenella, Erysimum sisymbrioides, Meniocus linifolius, Neslia paniculata, Sinapis arvensis, Sisymbrium volgense, S. brassiciforme, S. loeselii, Thellungiella mollissima, Turritis borealis) and taxonomic position of Alyssum desertorum and Thellungiella mollissima.
Integrált kockázatmenedzsment a gyakorlatban
Authors: Fekete István
Published: January 2021

A kockázatmenedzsment-szakirodalomban sok módszer található, amely alkalmas lehet a kockázatok becslésére. Ám ezek közül több csak akkor használható, ha megfelelő mennyiségű és minőségű múltbeli adat áll rendelkezésre. Azonban a legtöbb kockázat értékeléséhez sokszor nem érhető el ilyen naprakész adatbázis. Természetesen e kockázatok bekövetkezési valószínűségét és hatását is megbízható módon kell becsülni/értékelni. A kérdés csak az, hogy mi módon tegyük is ezt? A kérdés megválaszolására a szerző kidolgozott egy módszert, amit máig már több mint ötven projekt esetében alkalmazott sikeresen. Az alkalmazások során szerzett tapasztalatokat felhasználva a módszert továbbfejlesztette. Ez a cikk a továbbfejlesztett módszer újdonságait foglalja össze. A cikkben található egy esettanulmány is annak szemléltetésére, hogyan lehet az általa kidolgozott megközelítéssel a kockázatokat felmérni és kezelni.
A szerencsejátékok társadalmi és gazdasági hatásai, valamint a játékszenvedély prevenciójára alkalmazott nemzetközi gyakorlatok
Authors: Tessényi Judit
Published: January 2021

A szerencsejátékok társadalmi és gazdasági hatásait és a játékfüggőség kérdéseit elemzi az írás. Mind a hazai, mind a külföldi tanulmányokban találkozni lehet egy ellentétes irányú törekvéssel: egyrészt a szerencsejáték mint az állami bevételek növelésének lehetősége, másrészt mint az állami kiadások, a szerencsejáték-függőséggel kapcsolatos negatív események felszámolására tett erőfeszítések. A szerző dolgozatában a téma iránt érdeklődő kutatóknak olyan közgazdasági irányultságú nemzetközi módszertant mutat be, mely a szerencsejáték és annak különböző fajtáit vizsgálva segít azok gazdasági és társadalmi vonatkozásaiban eligazodni és a különböző – pozitív és negatív – hatásokat számba venni.
A fogyasztói érték és az élmény kontextusa a turisztikai szakirodalomban (The context of consumer value an experience in tourism literature)
Authors: Kulcsár Noémi
Published: January 2021

Tanulmányában a szerző a szakirodalomban fellelhető főbb fogyasztóiérték- és élménymegközelítéseket és kapcsolatokat mutatja be. A turizmus területére fókuszálva kitér az egyes érték és a hozzá szorosan kapcsolódó élménymegközelítéseken belül található nézetkülönbségekre és azonosságokra. A szerző célja, hogy bemutassa a turizmusszektorban tapasztalt fogyasztóiérték-megközelítések sokféleségét, alátámassza a fogalom tudományos szempontú tisztázatlanságát, valamint korábbi empirikus kutatások alapján összesítse a fogyasztói érték lehetséges dimenzióit a turizmusban. ____ In this paper, the author presents consumer value and experience approaches and connections found in literature. Focusing on the area of tourism she introduces value – experience connections, the differences and accordance among approaches of the experts, and the changes of the content of interpretations from time to time. The author set several targets with her work: introducing the diversity of consumer value approaches in tourism; proving the lack of the precisely and scientifically composed concept of consumer value; and based on former empirical researches summarizing the potential consumer value dimensions in tourism.
Domináns vállalat versenyképességének hatása az ellátási láncban (Effects of competitiveness of the dominant company in the supply chain)
Authors: Brányi Tamás , Józsa László , Seres-Huszárik Erika
Published: January 2021

Beszállító, gyártó és vevő vállalatok alkotnak egy ellátási láncot. Optimális esetben a vállalatok integrált rendszerben működnek, az együttműködés bizal mi alapon nyugszik, így a közös stratégiai döntések révén versenyképes lesz a lánc. Az ellátási láncban lehet egy kulcsfontosságú vállalat, amelyik domináns hatalmi pozícióval rendelkezik. A kutatás célja, hogy feltárja a hatalommal rendelkező vállalat szerepét a partnercégek és az ellátási lánc versenyképességének alakulásában. A szakirodalom alapján a hipotézis feltételezi, hogy van kapcsolat a versenyképesség és a domináns vállalat szerepvállalása között. A szerzők elemzése primer kutatáson alapul, a kérdőív válaszait SPSS statisztikai kiértékeléssel végezték. Az eredmények azt mutatták, hogy a domináns vállalat versenyképességétől valóban függ a partnercégek versenyképessége. Szignifikáns kapcsolat megléte bizonyítja a hipotézist. A vizsgálatok kiemelik, hogy a verseny már egy szinttel feljebb, az ellátási lánc szintjén értelmezhető: globális ellátási láncok versenyeznek egymással. _____ Supplier, producer and buyer companies make up a supply chain. In an optimal case the companies are integrated, partnership rests on trust which results in common strategic decisions leading to competitiveness. Each supply chain has a key company with dominant power position. The objective of the research is to analyse how the company with power affects competitiveness of partner firms and the supply chain as a whole. Based on theories hypothesis assumes a link between competitiveness and power position and its influence. Methodology of the analysis is based on primary research; the authors used SPSS statistical analysis to evaluate the answers of questionnaire. Findings include that partner firms’ competitiveness rely on competitiveness of the company with dominant power position. Significant connections prove that the hypothesis is true. Results show that competitiveness is being moved up to supply chain level. Global supply chains compete with each other.
