العوامل الداخلية الإقليمية الدولية التي أدت إلى انفصال جنوب السودان يوليو 2011م
Authors: النيسي د.إسكندر محمد
Published: June 2023

تهدف هذه الدراسة إلى معرفة وسرد وتشخيص وتحليل كل المنعطفات التاريخية التي رافقت أزمة دولة السودان الكبيرة، التي تتمتع بموقع استراتيجي هام على المستوى الإقليمي والدولي، وامتلاكها للثروات المختلفة، والمساحة الشاسعة التي يأتي ترتيبها (التاسع) عالمياً. وهذه الأزمة كانت مخفية على غالبية من الناس في العالم، ولم تظهر إلى مصاف الأزمات العالمية، ألا عند ما جاءت حكومة الإنقاذ الانقلابية إلى السلطة عام 1989م، وانتهاء الحرب الباردة، وتفكك الاتحاد السوفييتي. شاركت القوى الإقليمية والدولية والمحلية في تأجيج الأزمة، ومن يدفع الثمن، هو الوطن والمواطن السوداني الذي فقد التنمية، وتحولت مشاريعه إلى فتنة وتمزيق بنية الوطنية، ولم تقتصر أثار تلك الأزمة على الشمال والجنوب، وإنما امتدت فجوتها إلى كل الأقاليم السودانية التي أصبحت تتصدر المقدمة في وسائل الإعلام العالمية مثل(دار فور) بعد الجنوب. وتم الإعداد لفصل جنوب السودان من قبل أيادي سودانية قبل أن تكون خارجية. فالنخب السياسية، سلطة أو معارضة  لم تعرف التوحد منذ الاستقلال، من ما افقد التفاوض بين الجانبين من خلال عدة اتفاقيات بداً من اتفاقية المائدة المستديرة بأديس أبابا عام 1965م، إلى اتفاقية نيفاشا عام 2005م التي مهدت للعامل المحلي والإقليمي والدولي نحو الإعداد والتجهيز لتقرير مصير جنوب السودان بقيام دولة جديدة في 9 يوليو2011م.

Authors: الهادي د.بوقلقول , هاجر أ.برحايل
Published: June 2023

تعد العلامات من أكثر مظاهر الأسواق العالمية . لذلك تسعى المؤسسات إلى خلق مكانة مرموقة في البيئة التسويقية والتميز عن المنافسين، ولن يتحقق لها ذلك إلا إذا كانت تملك علامات قوية وفعالة. إذ يمكن القول في هذا السياق أن علامات المؤسسات الجزائرية لا تتمتع بالقوة ذاتها في السوق، لذلك تسعى المؤسسات إلى تقييم فعالية علامتها بهدف تعزيز مكانتها في السوق بالاعتماد على مؤشرين أساسيين: قوام العلامة من جهة وحيويتها من جهة أخرى.
    فهذه الورقة البحثية تتناول عرض دراسة ميدانية تم إجراؤها بإحدى مؤسسات العجائن الغذائية "صابة" ، من خلال استمارة تم توزيعها على عينة من المستهلكين لتقييم صدى العلامة لديهم . وقد توصلت هذه الدراسة إلى مجموعة من النتائج سنستعرضها  في هذه الورقة البحثية مع  التوصية بأهم الإجراءات التي نظن أنها قد تسهم في تعزيز علامة المؤسسات الجزائرية .

Air Corporate Governance and Suspicion of Corruption in Supply Chain Management: The Case of Tunis Air Airlines
Authors: Lakhal Salem Y. , Lakhal Camelia
Published: June 2023

The corporate governance of airlines companies is not a well studied area. As corruption is a criminal act, the issue is sensitive, and the doors are not opened for researchers. This article aims to contribute to the scarce literature surrounding this topic in order to overcome the lack of research. By staying studying this topic at a general lever and analyzing most of the supply chain activities of real airline companies, we can detect which activities within the supply chain present the most potential where corruption could take place. Propositions will be developed about the characteristics that need to be built into the value chain activities to be robust against corruption. These analyses and propositions are grounded in a case study of the Tunisian airline, Tunis Air. Although this company is not among the biggest airlines in the world, it’s governance could be a structural example in this area of study.
Inherent Relationship Between Transport Costing and Organizational Competitiveness: A Case of the Road Freight Sector in Zimbabwe
Authors: Mujakachi Tapiwa Christopher , Tukuta Marian , Tsvere Maria
Published: June 2023

The main aim of road freight transport is transporting of goods by road. It is the most developed area of transport. The advantage of road transport is the direct transport from the sender to the recipient, faster, easier transportation resulting from technology, availability and operability. The disadvantages of this type of transport are traffic intensity dependence on the state network of road infrastructure and negative impact on the environment. The significance of calculation in transport is so important. It helps carriers to inform on the efficiency and profitability of the services provided, also in allocation of pricing services for budgetary purposes, but also for reducing of cost. This study interrogated the inherent relationship between transport costing and organizational competitiveness in the Zimbabwe Road Freight Sector. The study was prompted by an observation that most road freight companies collapsed before even they reach the five-year mark of trading. Literature is awash with transport costing models and there seemed to be a disparity in the conceptualization and application of these to real business scenarios. That led to the use of somewhat firefighting costing strategies with no meaning results. This was a quantitative study of road freight transport sector across Zimbabwe with a population of 1256 registered companies and a randomly picked sample size of 384. A total of 384 questionnaires were distributed and 291 were retrieved giving a response rate of 75.6%. study found out that the idea of transport costing was alien in the minds of many operators and managers as they used borrowed rates from competitors to price their own services without looking at the cost build up to the rate. This led to unprofitable operations. The study findings established that transport costing has a positive effect on organizational competitiveness. The study recommends training and development into transport costing and inclusion of this concept as a stand-alone module in Zimbabwean Education curriculum.

DIMENSIONS OF MEASURES, DEGREES, AND FOLDING ENTROPY IN DYNAMICS
Authors:   Institute of Mathematics of the Romanian Academy, MIHAILESCU EUGEN
Published: June 2023

In this survey, we present some methods in the dynamics and dimension theory for invariant measures of hyperbolic endomorphisms (smooth non-invertible maps), and for conformal iterated function systems with overlaps. For endomorphisms, we recall the notion of asymptotic degree of an equilibrium measure, which is shown to be related to the folding entropy; this degree is then applied to dimension estimates. For finite iterated function systems, we present the notion of overlap number of a measure, which is related to the folding entropy of a lift transformation, and also give some examples when it can be computed or estimated. We apply overlap numbers to prove the exact dimensionality of invariant measures, and to obtain a geometric formula for their dimension. Then, for countable conformal iterated function systems with overlaps, the projections of ergodic measures are shown to be exact dimensional, and we give a dimension formula. Relations with ergodic number theory, continued fractions, and random dynamical systems are also presented.

Published: June 2023

We obtain asymptotic estimates of the dimension of cohomology on possibly non-compact complex manifolds for line bundles endowed with Hermitian metrics with algebraic singularities. We give a unified approach to establishing singular holomorphic Morse inequalities for hyperconcave manifolds, pseudoconvex domains, q-convex manifolds and q-concave manifolds, and we generalize related estimates of Berndtsson. We also consider the case of metrics with more general than algebraic singularities.
ON THE EMBEDDING OF LEVI-FLAT HYPERSURFACES IN THE COMPLEX PROJECTIVE PLANE (AND AN APPENDIX WITH L´ASZL´O LEMPERT)
Authors:   Sorbonne Universit´e Institut de Math´ematiques de Jussieu-Paris Rive Gauche, IORDAN ANDREI
Published: June 2023

Let L be a hypothetical smooth Levi flat hypersurface in CP2 and r the signed distance to L by means of the Fubini-Study metric g. Denote Lru = cru the second order elliptic equation for the infinitesimal Levi-flat deformations of L, where cr = dbJbr + br ∧ Jbr, br = ιXrdγr, Xr = gradgr/ ∥gradgr∥2 g, γr is the restriction of dcr to L and db is the differentiation along the leafs of the Levi foliation. Then −cr ≥ H as leaf-wise (1, 1)-forms, where H is the holomorphic bisectional curvature of CP2. We give also an example of a Levi-flat manifold L of dimension 3 verifying that there exists a (1, 0)-form α on L such that ∂α is a K¨ahler form on every leaf of the Levi foliation, but L is not embeddable in CP2.

Published: June 2023

El estudio tuvo como finalidad determinar las fuentes de financiamiento y capacidad de endeudamiento de los productores de maíz del cantón Mocache, provincia de Los Ríos, Ecuador. Se seleccionaron 76 productores: 43 pequeños (PP), 27 medianos (MP) y 6 grandes (GP) a quienes se aplicó una encuesta. Los resultados indican el 40% de los productores tienen entre 11 y 30 años de experiencia, la extensión de terreno dedicado a maíz va de 1 a 46 ha. Un 76% de los productores utilizan semilla certificada siendo INIAP 551 la más utilizada (69.7%), seguida por Dekalb-5005 y Vencedor R-8330 (19.7% y 18.4% respectivamente), mientras que el 22.2 % de productores utilizan semilla reciclada. El promedio de producción de maíz del cantón Mocache es 5.6 t.ha-1. Los PP acceden a prestamistas informales (agiotistas, comerciantes). Los MP y GP acuden a formales e informales (bancos, comerciantes y fomentadores). Las condiciones que establecen los financistas formales son varias pero, a excepción del Banco Nacional de Fomento (BNF), ningún banco ofrece un producto financiero específico para agricultura. La oferta financiera va de 100 a 20 000 USD por parte del BNF y de 2000 a 20000 de la banca privada, mientras que las empresas fomentadoras solo entregan el crédito en insumos. La rentabilidad obtenida fue de 27.10; 63.22 y 74.00 % para aquellos productores que tienen menos de 5 ha, de 5 a 20 ha y más de 25 hectáreas de maíz, respectivamente. Solo los grandes y medianos productores tienen capacidad de endeudamiento.

Ժողովրդագրական փոփոխությունների պատճառներն Արևմտյան Հայաստանի Դիարբեքիրի նահանգում (XIX դ. վերջ – XX դ. սկիզբ)
Authors: Բաբլումյան Արփինե Ռ․
Published: June 2023

Неотъемлемой частью политики Османской империи было изменение демографической картины Западной Армении в пользу турецко-курдских элементов. К основным причинам, повлиявшим на изменения демографической картины провинции Диарбекир, относятся перемещения армян внутри страны, когда население мигрировало из сельских районов в более крупные районы, заселенные в основном армянами, эмиграция (в этот период в основном в США), а также исламизация, которая была актуальна в XIX веке и особенно в годы гамидовских истреблений. Во многих населенных пунктах провинции Диарбекир основными причинами миграции были социальная, налоговая и религиозная политика империи в отношении к армянам, экономическое положение армянских крестьян, отсутствие собственности, насилие и массовые истребления с 1890-х годов.
An integral part of the Ottoman Empire's policy of persecuting the Armenians was to change the demographic profile of Western Armenia in favor of Turkish-Kurdish elements. The movements of the Armenian population of Diarbekir province, including migration within the country, emigration (mainly to the USA at that time), as well as Islamization, which was also actual during the XIX century and especially during the years of the Hamidian massacres, were the main causes that affected the demographic profile of the area. In other settlements of Western Armenia as well as in many settlements of Diarbekır province, the main reasons for emigration were the social, tax and religious discriminatory policies applied to the Armenian population, the economic situation of the Armenian peasants, the lack of ownership, violence, and the massacres that had been implemented in the 1890s.
The logics of and strategies to enhance generalization of mixed methods research findings
Authors: Younas Ahtisham , Durante Angela
Published: June 2023

Generalization of research findings is a cognizant action entailing careful examination and interpretation of findings drawn from specific samples and extrapolation of those findings to other diverse populations and settings. Approaches to generalization in qualitative and quantitative research have been discussed in the literature. However, there is limited discussion about the nature of generalization and strategies for achieving plausible generalization in mixed methods research. The purpose of this paper is to explore the logics of generalization in mixed methods and offer strategies to enhance generalization in mixed methods research. Three strategies namely, multilevel integration, comprehensive description of mixed methods and findings, and generating strong and plausible inferences and metainferences can enhance the extent to which findings of mixed methods studies can be translated outside of their own original context. These strategies may allow researchers to effectively combine qualitative and quantitative methodologies and generate findings for use in diverse contexts and settings.
Velhice e longevidade nos cotidianos da educação: rastreando (im)possibilidades nas (micro)políticas de currículo
Authors: Nunes Beatriz Bloise Pereira , Pocahy Fernando Altair
Published: June 2023

Este trabalho possui como objetivo refletir sobre a velhice, o envelhecimento e a longevidade no campo da educação. Dentre as questões levantadas, buscamos pensar a partir das seguintes perguntas: essa temática está presente na escola e/ou no currículo? Qual é a expectativa relacionada aos ambientes de ensino ao elaborar os sentidos da velhice e uma certa perspectiva de defesa da longevidade? Assim, nos interessa lançar o olhar sobre a maneira como os processos de escolarização mobilizam o trabalho de produção, marcação e regulação da diferença geracional e da longevidade. A investigação está pautada nos preceitos teórico-metodológicos pós-críticos a partir de uma metodologia que se empenha na descrição, análise e problematização de artefatos discursivos. Mais especificamente, os discursos presentes na BNCC (Base Nacional Comum Curricular) e no Estatuto da Pessoa Idosa, considerando que estes são produzidos de modo a engendrarem domínios e relações de poder, dando sustentação a determinados jogos de verdade, estando associados às produções de documentos oficiais e às políticas públicas relacionadas às pessoas idosas que se articulam com os cotidianos escolares da educação básica. Foi possível analisar como o debate sobre a velhice e o envelhecimento passa a se apresentar como uma “encomenda” na política pública de currículo – a BNCC – que é, atualmente, a principal proposta curricular para as escolas brasileiras. Além disso, buscou-se problematizar e ampliar o tipo de abordagem que a escola pode realizar para pautar as questões do envelhecimento, velhice e longevidade de maneira complexa e plural quando se propõe a refletir acerca de temas com tal relevância.

Published: June 2023

Aproveitando-se a ocorrência de um evento espontâneo de baixas temperaturas (<17 oC) em experimento de campo de arroz irrigado, coincidente com a fase reprodutiva da cultura, foram avaliados a produtividade, a porcentagem de esterilidade de espiguetas e o número de panículas por metro quadrado.  O experimento foi conduzido no sul de Santa Catarina, na safra 2019/2020, em delineamento de blocos ao acaso com três repetições no sistema pré-germinado. Do total de genótipos que compunham o experimento, 13 foram selecionados para comporem a análise principal, de esterilidade. Baseado numa série de estudos anteriores para estresse por baixas e altas temperaturas, a hipótese era de que a linhagem SC 806 se destacaria como resiliente. De fato, a SC 806 apresentou níveis de esterilidade significativamente menores que as testemunhas comerciais SCS116 Satoru, SCS122 Miura e SC 790 (SCS125), ao mesmo tempo que foi competitiva com as mesmas no tocante à produtividade. Assim, a SC 806 foi validada como resiliente a baixas temperaturas, confirmando o bom desempenho verificado em experimentos anteriores, e com isso demonstrando ser promissora como linhagem candidata à lançamento na forma de variedade.

Authors: Pereira Da Silva Bruno , Da Silva Domingos Thiago , Abeldaño Zuñiga Roberto Ariel
Published: June 2023

Existe un riesgo estadísticamente mayor de desarrollar comorbilidades mentales en el período perinatal. Existe un vacío científico en el análisis de la ocurrencia de problemas de salud mental en el período perinatal entre países de ingresos medios y bajos en el contexto de la Atención Primaria de Salud. Así, el objetivo de este estudio fue revisar la ocurrencia de trastornos mentales comunes en el período perinatal en la Atención Primaria de Salud en América Latina. Se identificó una estimación global del 37 % (IC 95 %: 32 %-43 %) de trastornos mentales comunes durante todo el período perinatal. A pesar de las altas frecuencias identificadas para los síntomas de comorbilidad mental, no hubo estudios en otros países de América Latina con excepción de Brasil, lo que impide un análisis sobre la salud mental de las mujeres latinas en el período perinatal.

The BCR::ABL1 translocation and the accompanying Philadelphia chromosome represents the first mutation which defined a disease, chronic myeloid leukemia. It also represents the first druggable target for which a specific compound was developed and accepted in current clinic practice, imatinib. Despite these, there are still areas in which the diagnosis and the best treatment sequence still needs investigation. One such context is the diagnosis and management of BCR::ABL1 positive myeloid neoplasms with ≥20% blasts, more specifically the differentiation between myeloid blast phase chronic myeloid leukemia and BCR::ABL1 positive acute myeloid leukemia. In this paper we present our recent experience with a BCR::ABL1 positive myeloid neoplasms with ≥20% blasts.
flexCAT: Computerized Adaptive Test Development Platform
Authors: Tu Dongbo , Luo Fen , Wang Daxun
Published: June 2023

Computerized Adaptive Testing (CAT) is a new testing mode that utilizes the adaptive measurement concept of "tailored to fit." Compared with traditional paper-and-pencil testing, CAT has the advantages of improving measurement accuracy, reducing test length, and ensuring test security. Therefore, it is highly regarded by researchers and practitioners both domestically and internationally. However, the platform construction of CAT involves complex statistical measurement theory and tedious numerical calculations, which hinder the application and promotion of CAT in practice.

Purpose: Schools in Japan were closed nationwide from March to May 2020 because of the coronavirus disease 2019 (COVID-19) pandemic. Many suspect that this school closure affected children’s mental and physical health. We investigated changes in school-age children’s physiques to determine the effects of the COVID-19 lockdown and restrictions on their health.Methods: Data were extracted from a database of school physical examinations in Osaka elementary and junior high schools for 4 consecutive years from 2018 to 2021. The following characteristics were analyzed: short stature, tall stature, underweight, mild obesity, middle grade obesity, and severe obesity. The paired Student t-test was used to compare school examination data in the prepandemic period (2018–2019), pandemic lockdown (2019–2020), and post-lockdown period (2020–2021).Results: Obesity rates in elementary school students aged 6–12 years, particularly in boys, were significantly higher during the lockdown than they were in 2019. After the pandemic, the tall stature rate continued to rise, while rates of short stature and underweight decreased in both sexes in 2020. In junior high school students aged 12–15 years, rates of obesity and underweight tended to decrease in 2020. However, these rates rebounded and rose in 2021 when the lockdown was lifted.Conclusion: During the COVID-19 pandemic lockdown, elementary school students gained weight, while junior high school students lost weight. The lockdown that was implemented during the COVID-19 pandemic had an unfavorable effect on weight gain, particularly in young school-age children.

Worldwide, colon cancer has become the fourth cause of death in terms of cancer. A high fiber and antioxidants diet help promote a healthy diet and prevent colon cancer. Black rice bran has high content both in fiber and phenolic. The aim of this research was to observe the potential of fermented black rice bran in improving colon conditions profiles of azoxymethane (AOM)-induced mice, comprising lactic acid bacteria (LAB) colony count, short-chain fatty acids (SCFAs) concentration, and malondialdehyde (MDA). Rhizopus oligosporus was used for fermenting the black rice bran. Five weeks old male Balb/c mice were divided into four groups (n=6) based on their diets. AOM was injected intraperitoneally and Dextran Sodium Sulphate was added to their drinking water, thus initiating inflammation in the colon. The number of LAB in faeces at the end of intervention in the groups of fermented rice bran group (FRB) (9.04±0.04 log CFU) and non-fermented rice bran group (NRB) (8.99±0.04 log CFU) were higher than that of the positive control group (8.33±0.06 log CFU/g) but fewer as compared to the negative control (9.63±0.05 log CFU). The concentrations of SCFAs (acetic acid, propionic acid and butyric acid) of the cecum content in the NRB group (11.92±0.00, 2.31±0.01 and 3.41±0.01 mM) were higher in the positive control group (8.90±1.30, 1.60±0.16 and 2.27±0.31 mM). As compared to the positive control group, the concentration of propionic acid of cecum content in the FRB group was higher (2.09±0.32 mM), but the concentrations of acetic acid and butyric acid were indifferent. The MDA level of the FRB group (1.41±0.03 µmol) was lower thanthat of the NRB group (1.88±0.05 µmol), and the MDA level of NRB was lower than that of the positive control group (2.03±0.09 µmol). The results showed that both FRB and NRB had a positive role in increasing the number of LAB, ALRP concentrations, and decreasing MDA levels in AOM-induced mice colons.

The use of bacterial probiotic metabolite-based active-packaging and coatings is an innovative approach that has gained widespread attention worldwide. Additionally, its utilization can lead to improvements in qualities and properties of food products. This study was aimed to develop a food spoilage prevention system using active food packaging and coating material in preventing food spoilage while increasing its shelflife. The materials used were bacterial cellulose (BC) based bioplastics fortified with fermented soymilk extracts (FSME) using Lactobacillus acidophilus as the producer of the antimicrobial and antioxidant agents. Moreover, the applications of FSME containing probiotic bacterial metabolites are discussed to highlight their efficacy in enhancing the quality and shelf life of food products.The antimicrobial test showed that the FSME could inhibit the growth of pathogenic microbial cultures at minimum inhibitory concentration (MIC) of 10% (v/v) as shown by clear zones, around colonies of E. coli (14.33±0.58 mm), S. aureus (18.33±6.03 mm), S. Typhimurium (11.67±1.15 mm), L. monocytogenes (11.33±2.31 mm), and B. cereus (13.33±3.06 mm). Meanwhile the results of IC50 for antioxidant activity test (µg/mL) indicated that the FSME showed radical scavenging activity against DPPH at approximately 75.27±2.552 (2.5%, v/v), 55.00±0.791 (5.0%, v/v), 43.17±1.603 (7.5%, v/v) and 15.05±0.346 (10%, v/v), respectively. The shelflife of strawberries coated with the active food coating using the bioplastic fortified with FSME showed an increase in shelf life of 14 days at 4°C. The overall results indicated that the use of BC based bioplastics fortified with FSME can play an important role in preventing premature spoilage and increasing the shelf life of food products.
De la propriété absolue aux communs : perspectives juridiques en droit civil québécois à la lumière des enseignements italiens
Authors: Warnier Stella
Published: June 2023

Le concept des communs prend une place de plus en plus importante dans la sphère juridique depuis une trentaine d’années. Les expériences italiennes concernant lesbeni comunisont sans doute parmi les initiatives les plus abouties de théorisation du concept. La gestion desbeni comunien Italie revêt des formes diverses, modelées par l’action des citoyen.ne.s et mobilisant le droit civil selon les besoins spécifiques en l’espèce. Il s’agit là du point de départ d’une réflexion plus large sur la forme que peuvent prendre les communs, ainsi que sur leur place dans le cadre juridique québécois.
Mais vous êtes donc communiste? Complément d’enquête sur les communs
Authors: Abraham Yves-Marie , Fourrier Ambre
Published: June 2023

Selon David Bollier, l’un des spécialistes les plus réputés du phénomène : « […] un commun, c’est : une ressource + une communauté + un ensemble de règles sociales » (Bollier, 2014, p. 27). En inscrivant notre démarche de recherche dans une perspective essentiellement sociologique, nous tentons d’abord dans cet article de préciser le contenu des « règles sociales » évoquées par Bollier. Ceci nous conduit à proposer un idéal-type du commun, à l’aide duquel nous explorons ensuite plusieurs organismes montréalais, dans le but de mieux cerner ce que nous proposons de nommer le processus de communalisation. Dans un second temps, nous discutons des apports et des limites de ce processus dans la perspective d’une stratégie interstitielle de sortie du capitalisme (Olin Wright, 2017), notamment par rapport à deux formes sociales voisines de celle des communs : les coopératives et les communautés intentionnelles. Nous considérons l’autoproduction comme l’une des caractéristiques importantes de la communalisation, que négligent bien souvent les principaux théoriciens des communs.

When the dispute goes in favor and the discourse represents the against: historical-philosophical concepts and their epochal transfer.
Resumen: Tras los conceptos se esconden tantas verdades como realidades y para elucidarlas extraemos, como si de un fluido se tratara, su destilada verdad. Plegado a su sentido etimológico original el verbo disputare implica una selección extractiva de aquello que se quiere orientar orgánica y adecuadamente. Por este motivo, el presente trabajo trata sobre los conceptos y su función generadora de disputas. Aprovechando la reciente publicación del volumen colectivo editado por Maximiliano Hernández y Héctor del Estal: Conceptos en disputa, disputas sobre conceptos (Dykinson 2022) se lleva a cabo un recorrido por las trece contribuciones que lo componen, cuya conexión es la de mostrar la pluralidad de perspectivas contenidas en un concepto, así como su transferencia histórica, política y epistemológica.
Abstract: Behind the concepts are hidden as many truths as realities and to elucidate them we extract, as if it were a fluid, their distilled truth. Folded to its original etymological sense, the verb disputare implies an extractive selection of what one wants to orient organically and adequately. For this reason, this paper deals with the concepts and their role as a generator of disputes. Taking advantage of the recent publication of the collective volume edited by Maximiliano Hernández and Héctor del Estal: Conceptos en disputa, disputas sobre conceptos (Dykinson 2022), a tour of the thirteen contributions that compose it is carried out, whose connection is to show plurality of perspectives contained in a concept, as well as its historical, political and epistemological transfer.
Evaluation of Pedestrian Level of Service at Signalised Intersections from the Elderly Perspective
Authors: Zhang Huiling , Zhang Dekai , Wang Ruihao
Published: June 2023

The crossing decisions and behaviour of elderly pedestrians are affected by the pedestrian level of service (PLOS). In this paper, an evaluation model was established to analyse the relationship between the traffic environment and the perceived evaluation of elderly pedestrians. Firstly, the characteristic parameters of the selected intersections and the perceived evaluation data of elderly pedestrians at the synchronisation scenery were extracted using manual recording and questionnaire-based truncation methods. The correlation between the perceived evaluation data of elderly pedestrians and the traffic parameters were tested with respect to the dimensions of safety, convenience and efficiency. Then, the significant parameters affecting PLOS were recognised. Based on the traffic characteristic parameters, the PLOS evaluation model from the elderly perspective was established using the fuzzy linear regression method. PLOS classification thresholds were obtained using the fuzzy C-means clustering algorithm. The data from two intersections were used to validate the model. The results show that the difference between the actual and the predicted PLOS values of the two crosswalks were 0.2 and 0.1, respectively. Thus, the proposed PLOS evaluation model in this paper can be used to accurately predict the PLOS from the elderly perspective using the traffic data of signalised intersections.

Authors: Stepanović Nemanja , Tubić Vladan , Zdravković Stefan
Published: June 2023

Current analytical free-flow speed models consider all rural two-lane highways as the same road type despite their different functional significance in the network. The aim of this paper is to develop a prediction model for free-flow speed as a function of speed limit and road geometric characteristics for different classes of rural two-lane highways. The research was conducted on 50 representative sections of the two rural classes of two-lane highways equipped with automatic traffic counters in Serbia. In order to develop the appropriate models, it was necessary to determine the threshold values of vehicle time headway in the free-flow for both classes of rural two-lane highways, based on the total number of 191,720 vehicles. The obtained results show that there are differences in the threshold values of free-flow time headway for different road classes. Namely, it was determined that the values of free-flow time headway for Class I amounted to 6.3 s, and for Class II to 8.4 s. The free-flow speed prediction model for different road classes showed that speed limit had the highest impact on free-flow speed for Class I and II highways, followed by horizontal curve radius and shoulder width.
The Impact of Migration of Road Freight Transport Services on Economic Indicators in Selected EU Countries
Authors: Zanne Marina , Twrdy Elen , Muha Robert , Batista Milan
Published: June 2023

Transport is an industry that generates a significant portion of national income and directly or indirectly employs a large number of workers, while supporting the existence and development of all other sectors of the economy. Despite the long-standing goal of decoupling economic and transport growth in the European Union (EU), freight transport volumes, especially road freight transport, continue to increase. This leads to a deterioration of the quality of life and the environment, but on the other hand also creates business opportunities. The question is which country’s haulers will benefit the most. Using a shift-share analysis, the authors provide an overview of the dynamics of the EU road freight market and select countries for closer examination. They then examine the extent to which the road freight sector contributes to national income in these countries. Using a regression analysis, they estimate transport prices and changes in turnover and gross value added (GVA) for selected countries due to market structure change. The results show that the sector’s turnover increased by 4% due to market changes, sectoral GVA deviated only slightly, and there was a loss of at least 8 billion EUR in GVA due to the shortage of truck drivers.
