Authors: Marcelino Araújo Júlian , Goldschmidt Rodrigo
Published: July 2022

O objeto deste estudo é a análise do julgamento do STF sobre as ações ADPF nº 324 e RE nº 58.25 nas quais se discutiram a constitucionalidade da terceirização das relações de trabalho. O objetivo geral deste estudo é analisar qual foi a linha de pensamento utilizada pelo STF no julgamento em questão. Os objetivos específicos são o levantamento do contexto histórico jurídico do mundo do trabalho, analisar os votos dos Ministros nos julgamentos da RE nº 958.252 e a ADPF nº 324 e, por fim, estabelecer uma análise crítica sobre o entendimento que preponderou no julgamento das relações de trabalho terceirizadas. O problema de pesquisa é: Qual foi o entendimento preponderante dos Ministros do STF ao julgarem inconstitucional a ilicitude da terceirização na atividade fim? A presente pesquisa concluiu que o resultado do julgamento em tela seguiu uma linha neoliberal, entendendo-se que tal decisão, ao menos na sua linha argumentativa, pretensamente terá impacto na economia, com o intuito de combater o desemprego, de acordo com o novo mundo tecnológico, bem como fomentar a competitividade, todavia podendo receber sérias críticas, já que a Constituição Federal preceitua a valorização do trabalho humano. Em um primeiro momento, o artigo faz uma breve recapitulação histórica, legal e sociológica da terceirização de serviços. Posteriormente o estudo procura descrever os atos que ocorreram nas sessões do STF. Por fim, analisa-se sucintamente a jurisprudência gerada com um olhar para os direitos fundamentais do trabalhador, contrapondo-se discursos e votos em sentido contrário. O presente estudo adotou o método dedutivo, subministrado pela técnica de pesquisa bibliográfica e documental.
EMPRESA CONTEMPORÂNEA E MEIO AMBIENTE DO TRABALHO: O DEVER DE TUTELA PARA ALÉM DA QUESTÃO NACIONAL E MONETARIZANTE
Authors: Matias João Luis Nogueira , Moreira Aline Lorena Mourão
Published: July 2022

Na análise da relação entre empresa e meio ambiente do trabalho aborda-se a necessidade de atuação empresarial em padrões éticos e sociais na contemporaneidade e a atuação das transnacionais, o que requer um viés transconstitucional para a sua melhor compreensão. Parte-se da seguinte pergunta: em um sistema capitalista, intensamente marcado pelo processo globalizante da economia, ainda seria uma questão apenas nacional e monetarizante o dever de tutela efetiva do meio ambiente laboral? Constata-se que as grandes empresas na contemporaneidade não possuem mais nacionalidade, no sentido de que atuam por todo o globo, na busca incessante do lucro, sendo necessário que o Direito se adapte a essa nova forma organizacional. Faz-se uma visão crítica, a partir do Direito Ambiental do Trabalho e da análise do ambiente laboral nas empresas frigoríficas. Destaca-se que o grande desafio que se revela é como compatibilizar o princípio da função social da empresa com os princípios da livre iniciativa e o da lucratividade, aplicando-se o paradigma protetivo emergente de tutela do meio ambiente laboral. Conclui-se que se impõe garantir a efetiva tutela jurídica preventiva, priorizando-se o meio ambiente laboral como um direito universal, garantindo-se a equidade na proteção ambiental a todos os trabalhadores, independentemente de sua nacionalidade, ao se tratar de empresas que atuam por todo o globo. Trata-se de pesquisa transdisciplinar. Utiliza-se o método dedutivo, com pesquisa bibliográfica e jurisprudencial.

Authors: Paula Sanzio Teixeira de , Melo Álisson José Maia
Published: July 2022

A crise financeira de 2008 evidenciou que o sistema bancário está fora de controle, propiciando o desenvolvimento de novos serviços financeiros ofertados por empresas que têm como escopo a inovação tecnológica. Após o marco regulatório instituído pela Lei 12.865/2013, o Sistema de Pagamentos Brasileiro (SPB) vem passando por modificações normativas do Banco Central do Brasil (BCB), buscando transformação tecnológica nesse setor. O princípio da interoperabilidade, instituído como norteador do sistema, tem como vertente a inovação como estímulo à competitividade, propiciada por um arcabouço regulatório focado no desenvolvimento ordenado do mercado. Este artigo investiga como e em que medida a inovação impacta no SPB, inclusive no âmbito regulatório, de modo a fomentar a competitividade, atuando como catalisador da concorrência. Quanto à metodologia utilizada, adota-se o método dedutivo, com pesquisas bibliográficas e exame dos normativos do BCB. A pesquisa justifica-se diante da atualidade do tema e da constatação do permanente processo de inovação no sistema financeiro, de modo a ensejar crescente redução da assimetria informacional. Conclui-se que o alcance da inovação através do incremento da interoperabilidade proporciona a competição, a não-discriminação e o desenvolvimento ordenado do mercado, conforme demonstra a essência dos novos vetores instituídos no âmbito regulatório. Todavia, o impacto que tais vetores proporcionarão nos meios de pagamentos ainda é desconhecido face ao seu estágio embrionário, mas o caminho está pavimentado de modo a demonstrar que a inovação como estratégia para fomento da competitividade é um trajeto sem volta.

Published: July 2022

This case study is aimed at exploring the development and role of Bayan traditional library as the source of information, education, and cultural preservation. The data were gathered through observation, interviews, and documentation. The study engaged traditional leaders, library managers, and Pokdarwis (tourism awareness group) as the informants. The study showed that Bayan traditional library was present among indigenous peoples due to the modernization which shifted the younger generation's paradigm to continue preserving culture. The library functions are as a forum to foster public interest in reading, a vehicle for Bayan traditional museum, and facilities for Bayan community to meet the book needs related to formal and informal education. It also provided numerous references for researchers to conduct research, learning facilities for local wisdom, and the arts of the native community. The library services are of course still conventional, as it can be seen from the concept of open library space, and circulation services are not organized technologically. Moreover, the role of the library in preserving culture is carried out by documenting various cultural activities, which are then translated into writings or works to increase the spirit of the younger generation to maintain cultural existence.

Published: July 2022

In 2020, the Simultaneous General Elections were held in many parts of Indonesia even during the Covid-19 outbreak. However, election offenses still occurred and even resulted in a new offense, which was the health protocols offense. The election offense records can be used as an indicator of democracy quality, besides its other roles. This paper will describe the role of archives related to election offenses. The study found that during the simultaneous election, the majority of offenses that occurred were administrative, code of ethics, criminal, and health protocols. The election offenses documents, in the archive context, become an important archive that is part of the election archive and can be grouped into types of election offenses archives, namely: health protocol offense archives, administrative offense archives, code of ethics offense archives, and criminal offenses archives. In addition, the archives can also be useful in the context of compiling infographic materials, comparison data, election policy, and mapping materials for better elections.

Published: July 2022

The field of information is undergoing a very rapid transformation with the use of information technology in every community activity. The use of information technology that is increasingly friendly in the community has facilitated work management to be more effective and efficient so as to accelerate performance. However, the diverse geographical conditions of society have led to a digital divide in technology accessibility in Indonesian society, while the rapid development of technology demands equal distribution of capabilities and mastery of technology throughout the wider community. As an institution that is an information center, the role of libraries is very important in encouraging people to use information technology through digital inclusion. Libraries can carry out the role of digital inclusion through the provision of technology tools, freedom of access by the community. This study examines the role of libraries in digital inclusion with students as part of a community group. The research was carried out with a quantitative approach through the distribution of questionnaires, to determine student responses regarding the availability of information technology devices provided by the library, their accessibility and ability to utilize these facilities. The results of this study found that the information technology facilities provided by the library and the ease of access have helped students to get information sources easily and quickly. The provision of adequate information technology facilities and easy access to libraries has played a role in helping students to become more familiar with digital devices, so that they can adapt quickly to any existing technological developments.

Authors: Ider Merve , Maden Mehmet
Published: July 2022

OBJECTIVE

To investigate the clinical value of selected biomarkers for evaluation of systemic inflammatory response and pulmonary inflammation and damage pattern in calves with different pneumonia forms.

ANIMALS

16 calves with fibrinous pneumonia (FP group; infected with Mannheimia haemolytica or Pasteurella multocida), 12 calves with caseonecrotic pneumonia (CNP group; infected with Mycoplasma bovis), and 10 healthy calves (C group) based on results of bronchoalveolar lavage fluid (BALF) examination.

PROCEDURES

Blood and BALF samples were collected. Annexin-A2 (Anx-A2), endothelin-1 (ET-1), calgranulin B (S100A9), transforming growth factor-β1 (TGF-β1), tumor necrosis factor-α (TNF-α), interleukin-17A (IL-17A), haptoglobin (Hp), lipopolysaccharide-binding protein (LBP), and albumin (Alb) concentrations and lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) activities were measured and compared across groups.

RESULTS

Serum concentrations of Anx-A2, S100A9, TGF-β1, TNF-α, IL-17A, Hp, and LBP and activities of LDH and ALP were higher and Alb concentrations were lower for the pneumonia groups versus C group. BALF concentration ratios of S100A9:Alb, LBP:Alb, LDH:Alb, and ALP:Alb were higher for the pneumonia groups versus C group (P < .05). BALF concentration ratios of Anx-A2:Alb, TGF-β1:Alb, and IL-17A:Alb were higher for the FP group versus other groups (P < .05).

CLINICAL RELEVANCE

Results indicated that serum Anx-A2, S100A9, TGF-β1, TNF-α, IL-17A, Hp, LBP, and Alb concentrations were useful in determining the systemic inflammatory response and that BALF concentration ratios of S100A9:Alb, TGF-β1:Alb, LBP:Alb, and ALP:Alb were useful biomarkers in determining pulmonary inflammation and damage. Measurements of BALF concentration ratios of Anx-A2:Alb, TGF-β1:Alb, and IL-17A:Alb could be beneficial to defining fibrinous characterization of pulmonary inflammation.

Quadrant-based contour features for accelerated shape retrieval system
Authors: Yildirim Mustafa Eren
Published: July 2022

Shape representation and retrieval are essential research topics of computer vision. This paper proposes a novel feature set to be used in content-based image retrieval systems. The proposed method is an extended version of our previous study which uses contour information of shapes. The previous study calculated the center of mass (CoM) of the shape. By taking the CoM as origin, we created imaginary vectors in every angular direction. From each vector, we extracted three features which are the number of intersections between vector and contour, average distance of intersection points to CoM, and standard deviation of these points. In this method, we extract novel features and decrease the size of the feature set to decrease the computation time. We divide the shape into quadrants and represent each quadrant by nine features. Each shape image is represented by a 4x9 feature vector. We tested the proposed method on MPEG-7 and ETH-80 datasets and compared it with the state-of-art. According to the results, our method decreased the computation time dramatically while giving a state-of-art level retrieval accuracy.
An efficient approach for sub-carrier allocation in MIMO MC-CDMA systems
Authors: Seyman Muhammet Nuri , Demiral Bircan
Published: July 2022

Sub-carrier allocation is an important process that directly affects users data and bit error rates for multi-user multi-carrier systems. The most important feature of the allocation process is to assign the sub-carriers to the active users in proportion to their needs to provide high-speed data transmission and reduce the bit error rates. In this study, an efficient subcarrier allocation algorithm has been proposed based on both capacity and fairness criteria for a MIMO MC-CDMA system, which is preferred as the multiplexing scheme in high data rate communication systems. The proposed algorithm achieves not only better error rate performance but also increases the total data rate compared to other algorithms

Asset Management of Existing Concrete Bridges Using Digital Twins and BIM: a State-of-the-Art Literature Review
Authors: Saback Vanessa , Popescu Cosmin , Blanksvärd Thomas , Täljsten Björn
Published: July 2022

The need to optimize investments in bridge maintenance has created a demand for improved bridge management systems (BMS). Outdated practices in bridge inspection and constant advances in information technology have also contributed to this demand. The use of Digital Twins (DT), although well established in other industries, is still incipient for asset management and structural analysis of bridges. There is a great deal of research on Building Information Modelling (BIM) for bridge inspection, but its post-construction potential is still under-explored. This study presents a state-of-the-art review of the literature on asset management for bridges using digital models such as BIM and digital twins. The review was conducting using a systematic approach. Despite the rapid increase in research on DT and the amount of existing research on BIM, several gaps remain to be addressed, such as the lack of consensus about the definition of digital twins, which has led to wrongful categorisation of digital models as DT. The complex data flow and software compatibility required to develop a functional DT have hindered the exploitation of their full potential so far. The integration of BIM post-construction to BMS and existing automation technologies can also significantly improve current practices of bridge management.
Board Structure and Bank Performance: The Mediating Role of Intellectual Capital
Authors: Nikolić Jelena , Nielsen Jelena Erić , Peković Jelena
Published: July 2022

Intellectual capital in the knowledge era is a strategic advantage of board structure, which leads to the improvement of a company’s work and the achievement of its goals. The aim of this study is to develop a structural model that connects the corporate governance, intellectual capital and financial performance of the banking sector. Corporate governance is conceptualised by the board of directors as the main internal mechanism of corporate governance, which is measured by the size of the board of directors, the number of independent board members and the female board members. Intellectual capital represents a mediator in this model and its efficiency is calculated through the Value Added Intellectual Coefficient (VAIC) model, while the financial performance of banks is measured through return on assets (ROA) and return on equity (ROE). The results of the study conducted in 22 Serbian banks between 2015 to 2019 show that the size of the board of directors and the number of independent board members have a statistically significant impact on intelectual capital (IC), but there is no impact on total assets (ROA). The number of women in the board of directors does not have a statistically significant effect on either ROA or ROE. The findings also indicate that intellectual capital (HCE, SCE, CEE) has a significant mediating role in the relationship between board structure and bank performance. The results of this study will provide a significant contribution to further investment in intellectual capital as the strongest link in achieving positive effects on bank performance.

Authors: Jordan Sandra , Zabukovšek Simona Sternad , Klančnik Irena Šišovska
Published: July 2022

One of the key activities of any company is the management of documents, which are created on a daily basis. Classic document management cannot follow the needs of the market for companies with a desire to be agile and modern. Therefore, companies need to offer employees a solution that allows them to carefully store and archive documentation, while at the same time giving them enough time to perform their main daily tasks. Electronic management of documents not only influences companies’ workflows, savings and adaptions to market needs but also influences their digital transformation. It is also necessary to consider the influences on the environment. The influence of the production and use of paper in daily business has burdened the environment a lot in the past and it is about time that this matter is addressed. Implementation of a document management system (DMS) is now almost a must-have for companies wanting to be competitive in the market and with a desire to digitalise its processes, and is also surely a good step in the right direction for the environment. The aim of this paper is to define the advantages of disadvantages of a DMS as part of companies’ digital transformation as well as to provide an overview of the process of implementation and to analyse future trends and predictions in this field. For better understanding, the authors also included some examples of the implementation of a DMS in Slovenian companies.

Published: July 2022

This paper studies the effects of the sintering temperature on crystal structure, critical temperature (Tc) and excess conductivity of Bi-Pb-Sr-Ca-Cu-O (BPSCCO) system. Bulk BPSCCO samples were fabricated by the solid-state reaction method. Four different temperatures of 835 °C, 840 °C, 845 °C, and 850 °C were applied to sinter four different samples. The crystal structure of the samples was investigated through X-ray diffraction measurements (XRD) and scanning electron microscopy (SEM). Superconductivity of the samples was analyzed by the temperature-dependent resistivity measurement. The experimental results showed the existence of both Bi-2223 and Bi-2212 phases in all samples. Quantitatively, the volume fraction of the Bi-2223 phase was found to increase from 53.56% to 75.97%, and the average grain size of Bi-2223 phase was observed to enlarge from 57.95 nm to 86.50 nm as the sintering temperature increased from 835 °C to 850 °C. In addition, the excess conductivity analyses based on the theory of Aslamazov - Larkin (AL) and Lawrence - Doniach (LD) showed decreases in the coherence lengths (ξc(0)) from 1.957 Å to 1.565 Å and the effective inter-layering spacing (d) from 79.7 Å to 64.5 Å. Meanwhile, the interlayer coupling strength (J) between two CuO2 planes was estimated to increase from 0.00083 to 0.00137. These results might be evidence to conclude that the increasing of the sintering temperature obviously improves the superconductivity in the BPSCCO system.

Authors: Manh Trung Tran , Tu Nguyen , Quang Nguyen Van , Trung Do Quang , Huy Pham Thanh
Published: July 2022

In this study, red-emitting AlPO4:Cr3+ phosphors have been successfully synthesized by a facile sol-gel method. The Tanabe–Sugano diagram demonstrates that the surrounding sites of Cr3+ ions has a high crystal field with Dq/B=2.47. The sharp 694-nm peak on the PL of AlPO4:Cr3+ phosphor could be attributed to the 2E→4A2 electron transition of Cr3+ ions. The AlPO4:0.3%Cr3+ phosphor presents the highest PL intensity, then a purple LED prototype is obtained by coating the optimum powder on a UV LED chip. The color coordinates (0.2412, 0.1330) of the purple LED prototype implies that AlPO4:Cr3+ phosphors are promosing to be used as deep red phosphor powder for horticulture LED lighting.

Published: July 2022

This paper presents the steady-state analysis results of the OECD/NEA and U.S. NRC PWR MOX/UO2 (MOX: Mixed Oxide) Core Transient Benchmark with the modern MCNP6 Monte Carlo code based on the ENDF/B-VII.1 evaluated nuclear data library. The purpose was to verify an MCNP6 model proposed for calculations of a heterogeneous MOX/UO2 fuelled PWR core, which has different neutronic characteristics from the popular homogeneous ones loaded with the UO2 fuel due to its partial loading of the MOX fuel. The effective neutron multiplication factors, assembly power distributions, and control rod worths calculated using MCNP6 showed a reasonable agreement within 390 pcm, 6%, and 175 pcm, respectively, with the available benchmark data. The discrepancies between the MCNP6 results and the benchmark data were also discussed. Consequently, these results obtained with MCNP6 and ENDF/B-VII.1 can be considered as a new full-core heterogeneous transport solution to supplement for the available benchmark solutions at the steady-state conditions.

Authors: Quang Huy Tran , Thi Thu Ha Pham , Binh Duong Tran , Quang Vinh Nguyen , Thi Hoang Yen Nguyen , Duc Tan Tran
Published: July 2022

Shear wave imaging (SWI) is a rapid and convenient method of collecting images of tissues in the region of interest. SWI is based on the mechanical properties of soft tissues named the complex shear modulus (CSM). The complex shear modulus consisting of the elasticity and the viscosity, is useful for diagnosing pathological tissue conditions. Previous studies have not fully exploited the estimation of CSM in the medium containing Gaussian noise and the shear wave's reflection phenomenon. In this study, we focused on the model of shear wave propagation in the 2D environment by the time domain finite difference method (FDTD), taking into account the effect of Gaussian noise and reflected shear wave. We then reduced the noise of the measured particle velocity using a designed least mean square filter. Finally, for direct estimation of CSM, Helmholtz algebraic inverse transformation algorithm was used. Reflected waves significantly affect the estimation of CSM, especially the tissue's viscosity, which is demonstrated by numerical simulation results.

This paper reported the impact of pH on the structure, morphology, and the green upconversion (UC) emission of Er/Yb/Mo tri-doped hydroxyapatite (HA) synthesized through hydrothermal method. X-ray diffraction confirmed that the pH of the solution strongly influenced the phase composition of the phosphors, and HA single phase was obtained at a high pH value. Transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) images of the phosphor exhibited rod-like morphology, and their length increased with increased of the pH values. Under laser-diode excitation wavelength of 975 nm, the phosphor showed typical upconversion emission bands of the  ion: strong green emission bands around 510-535/540-560 nm and weak red emission bands around 630-680 nm. The green and red emission intensity as a function of pH reached its maximum value at pH8. Finally, the emission intensity of
Effect of Electron – Phonon Interaction on the Magneto-optical Absorption in Monolayer Phosphorene
Authors: Long Hoang Dinh , Ngoc Hieu Nguyen , Trang Chau Thi Thao , Phuong Le Thi Thu
Published: July 2022

In this work, we investigate the magneto-optical absorption in a phosphorene monolayer subjected to a perpendicular static magnetic field. The magneto-optical absorption power is calculated using the projection operator technique taking account of the effect of electron – optical phonon interaction. Numerical results showed that in the case of absence of any interaction, the higher the resonant frequency, the smaller absorbed power was. If the electron - phonon interaction exists, there appear the cyclotron-phonon resonant peaks which show the electron transitions between Landau levels by absorbing a photon accompanied by absorbing/emitting an optical phonon. The obtained results are important for further studies and applications of the phosphorene based structures in optoelectronic devices.
Electric Field as A Novel Switch to Enhance Optical Absorption Spectra of Defect Blue Phosphorene Thin-films
Authors: Duy Nguyen Vo Anh , Triet Dang Minh , Anh Dinh Van
Published: July 2022

Improvement of the optical absorption coefficient is essential to enhance the light conversion efficiency of thin-film organic solar cells. Here we report the use of an external electric field as a novel switch to improve the optical absorption capacity of two-dimensional defect blue phosphorene (BlueP) systems. Using the density functional theory with van der Waals functionals, we investigate the structural, electronic, magnetic and optical absorption properties of the pristine, single-vacancy (SV) BlueP thin films, and a BlueP system absorbing a Vanadium adatom. We demonstrate that a SV BlueP layer would exhibit half-metallic and its absorption spectrum under an electric field parallel to the material plane is significantly enhanced in the ultra-violet region. More interestingly, when a Vanadium transition metal is absorbed on a pristine BlueP, the applied electric field perpendicular to the BlueP plane not only doubles the optical absorption coefficient, but also switches ON/OFF the magnetic moments of this system. The prominent red shift of the absorption spectra towards the visible light range under selected polarized directions paves a novel way to engineer solar cell devices with BlueP materials.

This research aims to determine the effect of several doses of liquid organic fertilizer of tomatoes on the growth of cocoa nurseries. Cocoa nurseries need nutrients that support the growth of cocoa seedlings. Liquid organic fertilizer of tomatoes contains the nutrients needed for the growth of cocoa seedlings. This research method was carried out experimentally with 6 treatments of POC doses of a mixture of tomato extract, coconut water, and rice water, with 4 replications. he results of the study, it was explained that giving a dose of 25 ml of POC mixed with tomato extract, coconut water and ricE water/ 100 ml of water had a good effect on the growth and development of cocoa seedlings for the character of seedling height, number of leaves and leaf length. Furthermore, for the character of stem diameter, no significant effect was seen on the increased in stem diameter of cocoa seedlings. To overcome this, it is necessary to increased the dose of fertilizer or add other organic materials that can increases the diameter of the cacao seedlings.

Cocoa is one of the plantation commodities which is a source of state income. Growing media is not only related to seed germination in general, but also relates to the ability of seeds to survive even in a less favorable environment. The purpose of this study was to determine the vigor of cocoa seeds of BL50 variety on several types of germination media. The research was carried out in Nagari Tanjung Lolo, Tanjung Gadang District, Sijunjung Regency from March to April 2022. The tools used consisted of a handsprayer, ruler, caliper, and writing utensil. The materials used in this experiment were BL50 variety cocoa seeds, crushed bricks, humus soil, sand, and insecticide. The experiment was arranged according to the rules of Randomized Block Design (CRD) with 3 treatments and 4 replications, and each replication consisted of 7 samples, with a total of 84 samples of cocoa seeds. The treatments given in this study were various sprout media, namely; A = crushed brick B = humus soil, and C = sand. The data were analyzed for variance, if significantly different, it was continued with the Honestly Significant Difference Test (BNJ). The results showed that humus soil media was a good medium for accelerating germination, while sand media was good for root development which included root length and diameter.

Though the suicide rate is remarkably high among older persons in many countries, seeking external assistance in dealing with suicidality is infrequent. Against this background, the objectives of this paper are twofold: to identify possible depressive signs and suicide warnings exhibited by older people before the act of suicide, and to examine the factors affecting the help-seeking behavior of older people who die by suicide. The study revealed that angry outbursts, sleep disturbance, isolation, reduced speaking, and thoughts of the meaninglessness of life are the significant possible signs of depression. However, only a few older persons directly expressed early warnings such as ‘talking about death or suicide.’ Yet, it seems that family members are unaware of the early warning signs. The study found four significant factors that limit the help-seeking behavior of older people dealing with suicidality: a weak social network, poor understanding of depressive and suicidal signs by family members, negative attitudes relating to old age culture, and a crisis of personal perspectives in help-seeking. We conclude that promoting mental health services to older persons and improving their help-seeking behavior in response to various life stressors would help prevent suicide in the older population.

"Ce recueil devait à l’origine présenter les actes d’une seule École doctorale en histoire des théories linguistiques1, mais ce livre a vite dépassé ce cadre thématique puisque nous publions ici les articles de chercheurs qui ont participé à d’autres écoles doctorales et / ou qui sont venus à l’Université de Lausanne dans le cadre de leurs recherches ou pour enseigner (cours universitaires, séminaires de 3ème cycle, colloques et conférences, projets de recherche, etc.). Les auteurs des articles publiés ci-après viennent de Suisse et de France, d’Estonie et du Brésil, de Russie, d’Italie et des États-Unis… Leur participation n’a pu que contribuer à la diversité thématique des sujets présentés dans ce recueil. Néanmoins, la thématique commune qui réunit toutes ces contributions reste toujours la même: il s’agit de l’histoire des idées linguistiques."
Marxisme et philosophie du langage (1929) de V. Vološinov et sa réception chez R. Šor: deux voies du développement de la science du langage «marxiste» dans les années 1920 en Russie
Authors: Tylkowski Inna
Published: July 2022

"Malgré le succès de Marxisme et philosophie du langage (par la suite MPL) deV. Vološinov, ce texte n’a suscité que trois comptes rendus. Le quatrième est ébau- ché par A. Romm. Resté à l’état de notes, ce compte rendu est bien étudié par les chercheurs contemporains. En revanche, le compte rendu écrit par R. Šor n’a ja- mais été analysé de façon détaillée. Notre article a pour but de combler cette lacune et porte sur le contenu de l’analyse critique de MPL faite par Šor. Son examen révèle que le compte rendu écrit par cette dernière et MPL de Vološinov représen- tent la formulation de principes de base diamétralement opposés de la science du langage «marxiste». Cela se manifeste dans la réception des idées de F. de Saus- sure. Si Šor considère la conception de ce dernier comme fondement de la linguis- tique «théorique» portant sur la langue en tant que système de signes (ou de «signi- fiances» dans les termes de Šor), Vološinov rejette la théorie de Saussure. Il la considère comme «abstraite», d’où le nom «objectivisme abstrait» qu’il donne au saussurisme. En élaborant la philosophie du langage «marxiste», il s’appuie sur la néo-philologie idéaliste (les idées de Vossler et de son École) définie dans MPL comme «subjectivisme individualiste». Vološinov propose d’étudier la «langue» comme fait réel, accessible à l’observation immédiate et non pas comme objet d’étude «théorique». Ce fait constitue une cible de la critique adressée par Šor à Vološinov."
L’histoire de la linguistique dans l’histoire de la littérature: exposé d’une méthodologie pour l’enseignement de l’histoire des idées linguistiques
Authors: Velmezova Ekaterina
Published: July 2022

"En enseignant l’histoire des idées linguistiques, l’une des techniques (qui permet à l’enseignant de captiver l’attention des étudiants durant une bonne partie de l’année académique, ainsi que d’aller à l’encontre de la division stricte des étudiants en«linguistes» et «littéraires») pourrait consister à s’appuyer sur la littérature. Dans cet article, nous distinguerons plusieurs procédés du travail correspondant avec les étudiants – comme la recherche de citations «linguistiques» cachées dans les textes littéraires, l’identification des prototypes des personnages-linguistes, l’analyse des théories linguistiques dominantes qui sont présentées dans les textes littéraires, la «correction» des «erreurs» linguistiques des écrivains, etc. À part les avantages purement pédagogiques que présente le travail lié à la découverte et à l’analyse des courants linguistiques dans la littérature, elle a un intérêt en tant que tel: même si les écrivains ne transposent que très rarement la linguistique dans leurs œuvres, on pourrait y distinguer quelques régularités qui se répètent d’un livre à l’autre. Cela permet de parler d’un texte de la linguistique dans la littérature (texte, dans le sens de cette notion introduit par les sémioticiens de l’École de Moscou-Tartu)."

"Habent sua fata libelli. Les livres ont leurs destinées – leurs auteurs aussi. Le livre de Christina Strantchevska-Andrieu (1967-2010) La découverte de la langue bulgare par les linguistes russes au XIXe siècle est la publication de sa thèse de doctorat soutenue avec beaucoup de succès à l’Université de Toulouse – le Mirail le 27 novembre 2009 devant le jury composé de son directeur de recherches, le professeur Roger Comtet (Université de Tou- louse – le Mirail), du professeur Jack Feuillet (INALCO, Paris), du profes- seur Michel Billières (Université de Toulouse – le Mirail) et de moi- même1. Cette thèse, consacrée aux études bulgares en Russie et rédigée en français, reflétait non seulement les intérêts scientifiques de la chercheuse, mais aussi, en partie, sa biographie où les côtés bulgare, russe et français étaient liés de façon très étroite."
Construction des connaissances dans un contexte d’apprentissage bilingue au niveau tertiaire : les réseaux conceptuels
Authors: Grobet Anne , Müller Gabriele
Published: July 2022

La question de la construction et de la transmission des connaissances dans le cadre d’un enseignement bi- ou plurilingue suscite actuellement de nombreuses recherches (Coste 2003, Gajo 2006, 2007, Moore 2006, Näf et al. 2009, etc.), mais elle ne semble avoir été que peu traitée au niveau tertiaire. Les corpus étudiés témoignent toutefois de l’intérêt particulier que revêt la construction des connaissances dans un tel cadre, où les savoirs ne sont, en principe, pas uniquement transmis, mais aussi problématisés. L’observation des données fait ainsi apparaitre l’existence d’un type particulier de séquence illustrant une telle problématisation : il s’agit d’une négociation orientée autour d’une « mise en réseau » de concepts proches d’un point de vue disciplinaire, aboutissant à la constitution de paradigmes conceptuels (Müller & Pantet 2008). Ces séquences sont étroitement liées à la dimension bi- ou exolingue des données, et elles constituent donc un terrain idéal pour observer les modalités de la construction des connaissances dans l’enseignement bilingue.
