The Mediating Role of Supply Chain Integration in the Relationship Between Supply Chain Strategy and Logistics Performance
Authors: Dağdeviren Ibrahim Ethem , Erturgut Ramazan
Published: November 2024

Businesses may face different challenges in the realization and management of supply chain activities. To cope with these challenges and be successful in supply chain management, companies need supply chain strategies that are suitable for their product structures and objectives and strategic collaborations based on co-operation among supply chain members. In addition, to control and improve the results of the activities and strategies, the performance of logistics activities, which have a large share in the economic development of companies, should be measured and managed correctly. Therefore, supply chain strategies, supply chain integration, and logistics performance measurements have a critical importance in supply chain management, where the competition of companies is experienced and complexity is increasing day by day. In this framework, this study aims to investigate the relationship between the supply chain strategies and logistics performance of an enterprise and whether supply chain integration has a mediating role in this relationship. For this purpose, 417 data samples were collected and analyzed from the top 1000 exporter companies determined by the Turkish Exporters Assembly by a survey method, and the findings are analyzed and discussed. In the literature, there is no study that analyzes the relationship between the variables determined in this research from a mediator variable perspective. Therefore, this study presents original research in this field, and it is expected that the findings of the research will provide important benefits to companies and researchers and offer a new perspective to the literature. As a result of the analysis, it was determined that there is a significant and positive relationship between the supply chain strategies determined by companies and their logistics performance and supply chain integration. There is also a significant and positive relationship between supply chain integration and logistics performance. In addition, it has been concluded that supply chain integration plays a partial mediating role in the relationship between supply chain strategies and logistics performance. These results suggest the importance of supply chain strategies and supply chain integration in improving logistics performance. Therefore, in line with the research results, it is suggested that, to use supply chains for competitive advantage, managers should ensure supply chain integration by determining the right supply chain strategies in accordance with their objectives and product structures, and thus increase their logistics performance.

Published: November 2024

Packaging constitutes the largest end-use market for plastics, accounting for approximately 40% of total consumption by sector. In 2021, the average plastic packaging waste generated per European Union (EU) resident was 35.9 kg, of which 14.2 kg, or around 40%, was recycled. The Directive on Packaging and Packaging Waste (94/62/EC), a pivotal environmental regulation, mandates specific recycling targets: a minimum of 50% of all plastic packaging waste must be recycled by 2025, increasing to at least 55% by 2030. These targets underscore the necessity for further advancements in the plastic and composite packaging waste sector. This review uses a PESTEL analysis to provide a comprehensive overview of six critical factors influencing the recycling of plastic and composite packaging waste. The PESTEL framework encompasses political, economic, socio-cultural (social), technological, environmental, and legal dimensions. This review underscores the key aspects of each factor that influences recycling. Moreover, the discussion outlines the key deficiencies within the recycling system for plastic and composite packaging waste, including factors such as inadequate technological capacity, the underdevelopment of the secondary polymer market, and the establishment of ambitious political targets that are challenging to attain, among others. The questions raised underscore areas that warrant further investigation.

Published: November 2024

The SARS-CoV-2 spike protein is pivotal in the COVID-19 virus’s life cycle, facilitating viral attachment to host cells. It is believed that targeting this viral protein could be key to developing effective COVID-19 prophylactics. Using in silico techniques, this study sought to virtually screen for compounds from the literature that strongly bind and disrupt the stability of the HSPA8–spike protein complex. To evaluate the interactions between the individual proteins and the protein complex attained from protein–protein docking using BioLuminate, molecular docking was performed using the Maestro Schrodinger Suite. The screened small molecules met all bioavailability conditions, Lipinski’s and Veber’s rules, and the required medicinal chemistry properties. Protein–protein docking of the spike protein and HSPA8 identified the optimal pose with a PIPER cluster size of 65, a PIPER pose energy of −748.301 kcal/mol, and a PIPER pose score of −101.189 kcal/mol. Two small molecules, NSC36398 and NSC281245, showed promising docking scores against the spike protein individually and in a complex with HSPA8. NSC36398 had a docking score of −7.934 kcal/mol and a binding free energy of −39.52 kcal/mol with the viral spike protein and a docking score of −8.029 kcal/mol and binding free energy of −38.61 with the viral protein in complex with HSPA8, respectively. Mevastatin had a docking score of −5.099 kcal/mol and a binding free energy of −44.49 kcal/mol with the viral protein and a docking score of −5.285 kcal/mol and binding free energy of −36.65 kcal/mol with the viral protein in complex with HSPA8, respectively. These results, supported by extensive 2D interaction diagrams, suggest that NSC36398 and NSC281245 are potential drug candidates targeting SARS-CoV-2 spike protein.

Published: November 2024

Flood disasters often result in significant losses of life and property, making them among the most devastating natural hazards. Therefore, reliable and accurate water level forecasting is critically important. Rainfall-runoff modeling, which is a complex and nonlinear time series process, plays a key role in this endeavor. Numerous studies have demonstrated that data-driven methods, particularly deep learning approaches such as convolutional neural networks (CNNs), long short-term memory (LSTM) networks, and transformers, have shown promising performance in water level prediction tasks. This study introduces the Conformer, a novel deep learning architecture that integrates the strengths of CNNs and transformers for rainfall-runoff modeling. The framework uses self-attention mechanisms combined with convolutional computations to extract essential features—such as water levels, precipitation, and meteorological data—from multiple stations, which are then aggregated to predict subsequent water level series. This study utilized data spanning from 1 April 2006 to 25 July 2021, totaling 5595 days (134,280 h), which were divided into training, validation, and test sets in an 8:1:1 ratio to train the model, adjust parameters, and evaluate performance, respectively. The effectiveness and feasibility of the proposed model are evaluated in the Lanyang River Basin, with a focus on predicting 7-day-ahead water levels. The results obtained from ablation experiments indicate that convolutional computations significantly enhance the ability of the model to capture the local relationships between water levels and other parameters. Additionally, performing convolution computations after executing self-attention operations yields even better results. Compared with other models in simulations, the Conformer model markedly outperforms the CNN, LSTM, and traditional transformer models in terms of the coefficient of determination (R2) and Nash–Sutcliffe efficiency (NSE) indicators. These findings highlight the potential of the Conformer model to replace the commonly used deep learning methods in the field of hydrology.
The Legal Personhood as an Instrumental Tool for Reforming the Governance of the Rhône River
Authors: Vallet Cyrille , Bréthaut Christian , Lussault Michel
Published: November 2024

Legal personhood has been recognized for several ecosystems worldwide, garnering significant attention from the scholarly community. This attention translated with the mobilization of approaches anchored into legal, institutional, or ethnographic perspectives. On-going calls for the recognition of Rhone River’s legal personhood provides us the opportunity to analyze on-going processes in a transboundary river located in the middle of Europe. This paper focuses on how such a concept gets promoted and intends to make its way on the political agenda. Specifically, we examine two current promoters of the legal personhood of the Rhone River: the International Commission for the Protection of Lake Geneva (CIPEL) and ID-Eau. We identify five key lessons: (1) the request for recognition of legal personhood derives from actors’ willingness to change current governance practices and to shift the productivist paradigm towards more decentralized and inclusive governance system; (2) legal personhood is presented as a solution to problems that have not yet been clearly framed nor identified, opening up thinking on how such concept may be instrumentalized; (3) the discussion remains limited to a small number of experts; (4) the legitimacy of this debate requires scrutiny; (5) the legal personhood concept should be reinterpreted to fit within Western ontologies.

Published: November 2024

This paper presents a Compact Integrated Water–Land Survey System (CIWS), which combines a remote sensing camera and a LiDAR module, and proposes an innovative underwater topography retrieval technique based on this system. This technique utilizes high-precision water depth points obtained from LiDAR measurements as control points, and integrating them with the grayscale values from aerial photogrammetry images to construct a bathymetry retrieval model. This model can achieve large-scale bathymetric retrieval in shallow waters. Calibration of the UAV-mounted LiDAR system was conducted using laboratory and Dongjiang Bay marine calibration fields, with the results showing a laser depth measurement accuracy of up to 10 cm. Experimental tests near Miaowan Island demonstrated the generation of high-precision 3D seabed topographic maps for the South China Sea area using LiDAR depth data and remote sensing images. The study validates the feasibility and accuracy of this integrated scanning method for producing detailed 3D seabed topography models.

Published: November 2024

A pesar de la alta demanda de ajonjolí (Sesamum indicum L.), tanto para el consumo nacional como para exportación, durante más de dos décadas no se han liberado nuevas variedades debido a que durante ese tiempo, en México no se han realizado trabajos de mejoramiento genético. Con el propósito de explorar la diversidad fenotípica y comportamiento del germoplasma de ajonjolí disponible en bancos, algunas variedades mejoradas y otros materiales introducidos en dos sitios que comprenden cuatro ambientes del estado de Guerrero, México fueron evaluados 50 genotipos, en los ciclos PV-2021 y PV-2022 con base en 24 descriptores morfológicos, siendo 11 cuantitativos y 13 cualitativos. Se realizaron análisis de componentes principales, de correspondencia y de conglomerados. Las variables cuantitativas que mostraron mayor relevancia para distinguir los genotipos fueron longitud y anchura del limbo, días a inicio de floración, altura de planta, número de nudos hasta la primera flor y días a inicio de madurez de cápsulas, mientras que las variables cualitativas de mayor importancia fueron grado de lobulado del limbo, relación longitud/anchura del limbo, número de ramas por planta, desarrollo de nectario extra floral y número de flores por axila foliar. El análisis de conglomerado condujo a la formción de dos grupos con base en caracteres de similitud dentro de grupos y disimilitud entre grupos. En similitud, 39 genotipos (78 %) se aglomeraron en el Grupo I, y 11 genotipos (22 %) en el Grupo II, mientras que en disimilitud, el Grupo I presentó 0.25 de distancia fenotípica y 0.38 para el Grupo II. Si bien hay un alto porcentaje de similitud fenotípica en el germoplasma evaluado, existen al menos dos grupos genéticos de variabilidad que pueden proporcionar, mediante cruzamientos y recombinación, nueva diversidad aprovechable por los programas de mejoramiento genético del ajonjolí.

Published: November 2024

This paper demonstrates the miniaturization of microstrip patch antenna through the induction of fractal geometry. By using the space filling properties of fractals, a unique patch antenna operating at 2.20 GHz is achieved as compared to conventional antenna which is operating at 2.46 GHz frequency, this is due to the increase of electrical length which is inversely proportional to operating frequency. The design starts with an insert-fed patch antenna which is subjected to fractal iteration using a new version of Sierpinski fractal up to the 3rd iteration. Experimental results show size reduction of 31%, 32% and 33% for 1st, 2nd and 3rd iterations respectively. Not only size is reduced but also the antenna maintains performance characteristics such as reflection loss, impedance matching, antenna gain. Additionally, the propose design achieves an increase bandwidth of over 3%, which illustrates the performance get better while maintaining the frequency. The results are evidence that proposed design provides superior size reduction and improved the bandwidth to previous design.
An Energy Efficient Tree-Based Routing Protocol for Wireless Multimedia Sensor Networks
Authors: Rashid Sharmin , Khan Md. Ridgewan
Published: November 2024

The recent technological advances in micro electromechanical systems have promoted the development of a powerful class of sensor-based distributed intelligent systems capable of retrieving multimedia information, namely Wireless Multimedia Sensor Networks (WMSNs). WMSNs are gaining more popularity day by day as they are envisioned to support a large number of both non-real time and real-time multimedia applications. Routing in WMSN is very challenging task. Multipath establishes several path for data transmission rather than single path. In this paper we proposed An Energy Efficient Tree Based Multipath Routing for WMSN’s (EETMRP) technique that will intend to provide a reliable transmission of data for data synchronization at the destination node with low energy consumption. This is done by efficiently utilizing the energy availability and the received signal strength of the nodes to identify multiple routes to the destination. EETMRP discusses that all of the packets of audio, image and scalar data are spread over the nodes lying on different possible paths between the source and the sink, in proportion to their residual energy and received signal strength. The objective of EETMRP is to assign more loads to highest energetic paths and fewer loads to lower energetic paths so that uniform resource utilization of all available paths can be ensured. It uses multiple paths between source and the sink which is intended to provide a reliable transmission environment with low energy consumption, by efficiently utilizing the energy availability of the nodes to identify multiple routes to the destination and efficiently balanced the loads of all sensor nodes. We also focused on node failure and it recovery process during packet transmission and during the start of packet transmission. Finally we proposed an algorithm based on our proposal to simulate and analysis our proposed routing protocol.

Authors: Chen Weitian , Bai Songyang , Gao Zihan
Published: November 2024

This study investigated the distribution of MBTI personality types among physics undergraduatesat Zhejiang University and analyzed their career aspirations, family income and mental health status.A comprehensive survey of 68 questions, including 52 multiple-choice questions and 16 short-answerquestions, assessed various personality traits and their correlation with academic intent and emotionalstate. The results showed that INTJ and INTP personality types showed the most significant tendencyto pursue academic research. They usually come from middle and above-class backgrounds. Notably,these two personality types accounted for about 41% of the total surveyed population, while NT typescombined accounted for about 58%. This indicates that although NT personality is more suitable foracademic research, students with introverted tendencies are more suitable. Research has further shown that people with ISTJ personalities often exhibit unexpectedly strong academic interests. In addition, individuals who aspire to enter academia generally maintain a stable state of mind, as evidenced by their consistent work efficiency in the face of personal challenges. Interestingly, although some aspiring academics come from financially stable families, most have encountered financial constraints. These results contribute to a deeper understanding of how personality traits and socioeconomic factors influence the academic career paths of physics students

По какой-то причине противоречия продолжали накапливаться, несмотря на договор 1392 года, который не помог избежать эскалации конфликта между Великим Новгородом и Ганзейским союзом. Наряду с известными проблемами в торговле и дипломатии, анализ заключений ганзетагов, купеческой переписки и посланий городов помог выявить уникальные причины пролонгации Нибурова мира в 1417 году и охарактеризовать кризисную ситуацию указанного периода. Автор исследования акцентирует внимание на борьбе условного лидера Ганзейского союза Любека и ливонских городов за главенство на Немецком подворье в Новгороде во время расстройства торговых связей. Подобное положение дел становится определяющим в развитии правовых отношений и договорной практики в рамках русско-ганзейских отношений в XV веке.

The first quarter of the XV century was marked by a crisis in Russian-Hanseatic relations. For some reason, the contradictions continued to accumulate, despite the peace treaty of 1392, which did not help to avoid escalation of the conflict between Veliky Novgorod and the Hanseatic League. Along with well-known problems in trade and diplomacy, an analysis of the conclusions of the Hanseatic League, merchant correspondence and messages from the cities helped to identify the unique reasons for the extension of the Peace of Niebuhr in 1417 and characterize the crisis of this period. The author of the study focuses on the struggle of the conditional leader of the Hanseatic League of Lubeck and Livonian cities for dominance in the German compound in Novgorod during the rupture of trade relations. This situation becomes crucial in the development of legal relations and contractual practice within the framework of Russian-Hanseatic relations in the XV century.

Публикуемые письма известного археографа В.Н. Сторожева расширяют круг корреспондентов выдающегося отечественного историка С.Ф. Платонова. Небольшая подборка сохранившейся корреспонденции позволяет проследить не только взаимные отношения между ними, но и, что важно, определить круг вопросов, интересовавших их. Конкретизируются научные интересы В.Н. Сторожева, становятся известными новые подробности дискуссии, развернувшаяся вокруг третьего тома «Истории России» Д.И. Иловайского. В опубликованной рецензии С.Ф. Платонова В.Н. Сторожев увидел мягкость критики и высказывал своё недоумение. Большая заслуга принадлежит В.Н. Сторожеву в публикации целого пласта актовых материалов, касающихся истории дворянства XVII в. ряда губерний центральной России. Его археографическая и публикаторская деятельность отличалась целеустремлённостью и была плодотворной, однако, не все задуманные планы удалось осуществить. Письменное общение было непродолжительным и прекратилось в начале 1900-х гг.

The published letters of the famous archaeographer V.N. Storozhev expand the circle of correspondents of the outstanding Russian historian S.F. Platonov. A small selection of preserved correspondence allows us to trace not only the mutual relations between them, but also, importantly, to determine the range of issues that interested them. The discussion that unfolded around the third volume of D.I. Ilovaisky's History of Russia is being concretized and filled with new facts. In the published review by S.F. Platonov, V.N. Storozhev saw the mildness of criticism, and expressed his displeasure. Great merit belongs to V.N. Storozhev in the publication of a whole layer of assembly materials concerning the history of the nobility of the XVII century in a number of provinces of central Russia. His archaeographic and publishing activities were characterized by purposefulness and were fruitful, but not all his plans were realized. Written communication was not long-lasting and stopped in the early 1900s.

Authors: Н.В. Белошапка
Published: November 2024

Данная статья посвящена изучению наиболее эффективной формы культурной дипломатии второй половины 1960-х – первой половины 1980-х гг. – артистическому обмену. Эффективность артистического обмена оценивалась по двум параметрам: финансовая прибыль и налаживание профессиональных контактов между представителями советской творческой интеллигенции и зарубежными деятелями культуры. Автором представлены сведения, позволяющие суммировать основные принципы, которых придерживалась советская сторона при заключении соглашений об артистическом обмене. В качестве показательных примеров при рассмотрении значимых аспектов заявленной темы использовались факты, зафиксированные в архивных материалах Министерства культуры СССР и Госконцерта СССР. Анализ ряда документов, основными из которых являются протоколы соглашений об артистическом обмене, позволил выделить причины срыва заграничных гастролей, не связанные с изменением международной обстановки в указанный период.

This article is devoted to the study of the most effective form of cultural diplomacy in the second half of the 1960s and the first half of the 1980s – artistic exchange. The effectiveness of artistic exchange has been assessed by two parameters: financial profit and the establishment of professional contacts between individual representatives of the Soviet creative intelligentsia and foreign cultural figures. The author presents information that allows us to summarize the basic principles that the Soviet side adhered to when concluding agreements on artistic exchange. As illustrative examples, when considering certain aspects of the stated topic, the facts recorded in the archival materials of the USSR Ministry of Culture and the USSR State Concert have been used. The analysis of a number of documents, the main of which are the protocols of agreements on artistic exchange, allows us to identify the reasons for the disruption of foreign tours that are not related to the change in the international situation during this period.

Several challenges to climate change and the circular economy feed the current and growing demand for sustainable new materials. In the case of the construction industry, carbon emissions and natural resource depletion are issues of special concern. Waste marble (WM), which is currently produced during the processing of naturally available marble rock worldwide, is a potential risk to contamination of the environment. Therefore, the development of WMs for use in concrete mixes is of great interest. In this study, a WM sample was characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The sample was then tested as additive (with 0 %, 3 %, 7 % and 10 % of WM respect to cement content) in the preparation of concrete mixes. Results showed that WM is mainly composed of calciteand quartz. The particle sizes were typically between 10 µm and 20 µm but submicron particles were also observed. We also found some improvements in the compressive strength of the concrete mixes after 28 days of curing, particularly with both 3 % and 7 % addition of WM. However, an increase in the WM content from 0 % to 10 % did not improve the compressive strength, indicating that there is a limit to the beneficial addition of these WMs to concrete mixes. Further analyses by Fourier transform infrared spectroscopy (FTIR) suggest that small amounts of WM may contribute to the enhancement of the formation of calcium-silicate hydrate (C-S-H).
Elevating Software Defect Prediction with a Hybrid AutoGluon-SMOTE Strategy on the NASA Project Dataset

Published: November 2024

The pervasive incorporation of devices into our everyday lives has increased our dependence on a range of software systems. Any malfunction in essential software can result in substantial repercussions. Over the past decade, numerous software defect prediction models have been proposed, with their effectiveness largely relying on careful hyperparameter tuning to achieve optimal outcomes. Automated Machine Learning (AutoML) has emerged as a solution to streamline this process by automating key tasks like algorithm selection, model combination, and parameter tuning to fit specific datasets. Among several AutoML platforms, including TPOT, H2O, AutoWEKA, auto-sklearn, AutoGluon, and Google AutoML Tables, AutoGluon is widely recognized for its flexibility and performance. However, AutoGluon struggles with imbalanced datasets, a common issue in software defect prediction where defective software instances are outnumbered by non-defective ones. To address this limitation, this study integrates AutoGluon with the Synthetic Minority Oversampling Technique (SMOTE), resulting in an enhanced AutoML framework called AutoGluon SMOTE. This integration not only tackles class distribution imbalances but also eliminates the need for additional hyperparameter adjustments, making the process more efficient. Experimental results indicate that AutoGluon SMOTE significantly outperforms the original AutoGluon, demonstrating improvements in key performance metrics: accuracy, precision, recall, F1 score, and AUC, with respective increases of 33%, 26%, 58%, 60%, and 13%. Additionally, when compared to traditional machine learning models, AutoGluon SMOTE delivers a performance boost ranging from 10% to 25%, further solidifying the effectiveness of this approach. These findings highlight the potential of AutoGluon SMOTE to streamline the machine learning process, making it more accessible to users with limited programming expertise, while reducing reliance on expert data scientists for hyperparameter tuning, preprocessing, and feature engineering.
